Hubble Space Telescope(n.)
A large astromical optical telescope placed into orbit around the earth, from which, in the absence of absorption and distortion by the earth's atmosphere, clear high-resolution images of astronomical objects can be obtained in the visible, infrared, and ultraviolet wavelengths. The telescope was launched into orbit on April 24, 1990. Since then the telescope has taken thousands of images, many of them unique, recording never before seen astronomical phenomena. Service missions were performed in 1993 and 1997, during which astronauts upgraded or replaced equipment on the telescope. Link to Hubble Telescope Information.
Hubble Space Telescope
The Hubble Space Telescope is a space telescope that was carried into orbit by a Space Shuttle in 1990 and remains in operation. A 2.4-meter aperture telescope in low Earth orbit, Hubble's four main instruments observe in the near ultraviolet, visible, and near infrared. The telescope is named after the astronomer Edwin Hubble. Hubble's orbit outside the distortion of Earth's atmosphere allows it to take extremely sharp images with almost no background light. Hubble's Deep Field has recorded some of the most detailed visible-light images ever, allowing a deep view into space and time. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe. Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy. The HST was built by the United States space agency NASA, with contributions from the European Space Agency, and is operated by the Space Telescope Science Institute. The HST is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.

Investigation of Synthesized ZnO Nanoparticles
In the present study, undoped ZnO and Mn, Cu and Co doped (5 mol%) ZnO nanoparticles have been synthesized by hydrosis method and structural, optical, magnetic properties of these samples have been performed. Crystal sizes of the undoped and doped ZnO nanoparticles have been determined to be ∼12 nm by XRD analysis. The crystallite size of ZnO nanoparticles have been observed to be decreased by doping process. A single, broad and unresolved EPR signal with additional two resonance peaks, Ia and Ib which are believed to be related with oxygen and zinc damage centers, and have been arised for the undoped ZnO nanoparticles. Six resolved, four resolved and a single unresolved EPR resonance signals were also recorded for the Mn, Cu and Co doped ZnO nanoparticles, respectively. UV irradiation caused some organoleptic changes for undoped and doped ZnO nanoparticles. Also, some new EPR resonance lines have also been arised for UV-irradiated ZnO nanoparticles which were accepted to be originating from the formation of oxygen and/or zinc damage centers during the UVirradiation process. From UV-Vis studies, the absorbance peaks for the synthesized ZnO nanoparticles have been appeared at ∼360 nm and the mean gap energy was calculated to be 3.20-3.32 eV. The band gap enery of undoped ZnO have found to be decreased by doping process.

Two mine scale trials were conducted to asses the reliability of wireless data transmission through rock and the ability to get qualitative subsurface deformation measurements. The System performed successfully fulfilling both objectives of the trials and allowing the installation procedures, data acquisition and management and communication protocols to be tested and validated.
This video, produced by CSIRO, talks about the project that Elexon Mining is working on with its partners.
Elexon Mining has developed Geo4Sight; a wireless subsurface monitoring system for challenging geotechnical environments where the use of cabled monitoring systems is impossible, impractical or unreliable.
Geo4Sight is initially offered as two distinct solutions:


Fing is an app that has a number of different purposes. It can scan for devices that are connected to a specific wifi network, ping devices or sites, find open ports, and perform other functions as well.
In some ways, it’s similar to nmap, though it’s a bit simpler to learn and use. Can you already hear the experts saying, “It’s for noobs”?
Nmap will be covered in a future post. Anyhow, when you scan a network with Fing, it will display all of the internet of things (IoT) devices that it picks up on that particular network:
These may include smartphones, routers, laptops, fitness trackers, etc. Part of why this is useful is that it can help you identify unauthorized devices on your network. From this menu, you can select a specific device and perform several different actions: ping, traceroute, find open ports, or wake on LAN.
Ping, as on the Linux terminal, is intended to determine the reachability of another device from the host device (yours). Hit the “Start” button, and Fing will send data packets to the specified device. Afterward, it will display the round-trip time on a graph:
Traceroute (which can also be performed on the Linux terminal) maps the trip that a data packet takes when going from its source to a destination. For example, moving from your smartphone to a router, or to your smart TV. On Fing, when you perform this command, it will display the IP address of the targeted host, how many hops the data packet took on the route, and the average time it took for it to reach its destination.
Likewise, the “find open ports” option searches for open TCP ports, both to search for available services and to seek vulnerabilities.
As you can see, in this instance, open ports on the specified device are 53 (DNS), 80 (http), 443 (https), and 8080 (http-proxy). A similar test can be performed in Linux using the cat command.
While all of these commands can be used via the Linux terminal as well, Fing combines them into a simple interface which is also easy to learn. Overall, it’s an extremely helpful tool which, as a side benefit, can help you learn computer networking.


Types of CCTV Cameras
A CCTV camera system is the best security measure one can take to protect his family or customers. It doesn’t just record footage, but it can also be used to scare away any potential threats. CCTV camera surveillance systems come in different types. Which kind of cameras one should go for depends on the requirements of an individual. Several CCTV installers in Dubai can serve your needs.
Where some camera systems are for indoor use, others are for outdoors. Indoor cameras need not be weather-proof or sturdy as the cameras which are to be installed outside must be. It also depends on whether the cameras are to be installed at a house or property or a retail store or place of work. Then several features need to be considered such as the viewing angle, focal distance, visibility, etc., of the cameras.
Here are the basics about a few significant types of CCTV cameras that are widely used:
As the name suggests, these types of cameras have a dome like a shape. This shape makes it difficult for people to spot which direction’s footage the camera is capturing. These cameras are clearly visible hence they are good at warning intruders that everything is being caught on camera. Some of them have infrared illuminators which help them record the video even in dim lighting. Dome cameras are used for video surveillance indoors mostly in retail spaces.
High-definition cameras capture footage at a higher resolution that enables the owner to zoom in without compromising the quality of the images. They capture finer details and hence are used in banks and other such places.
These cameras can be used 24/7 as they capture imagery perfectly despite the lighting conditions. They have an extra sensitive imagining chip that enables them to record footage no matter there is direct sunlight or the area is very poorly lit. Due to this reason, they do not need an infrared illuminator and are used outdoors.
The PTZ cameras allow for the lens to be panned, tilted or zoomed. They can either be programmed or controlled manually. Their high-end features give the operator more control over viewing. They are used in sensitive zones where live monitoring is essential.
These cameras have a long, cylindrical and thin design. They are used for long viewing hence these are mostly installed outdoors. Since they are for longitudinal outdoor viewing, they are usually weather-proof, with protective casings. They can capture footage that is at 40ft at a viewing angle of 80 degrees. They have either fixed lens or a varifocal one and capture footage of a fixed area.
These cameras use detachable lenses. They mostly have a varifocal lens whose focal distance and the viewing angle can be fine-tuned. A C-Mount camera with different lenses can be used to suit different needs.
If you are looking for professional installation then one of the best CCTV installers in Dubai is Alayoubi technologies. It provides top-notch quality along with reliability.


Null modem overview
The purpose of a null-modem cable is to permit two RS-232 "DTE" devices to communicate with each other without modems or other communication devices (i.e., "DCE"s) between them.
To achieve this, the most obvious connection is that the TD signal of one device must be connected to the RD input of the other device (and vice versa). Also, however, many DTE devices use other RS-232 pins for out-of-band (i.e., "hardware") flow control. One of the most common schemes is for the DTE (the PC) to assert the RTS signal if it is ready to receive data (yes, it DOES sound backwards, but that's how it works), and for the DCE (the modem) to assert CTS when it is able to accept data. By connecting the RTS pin of one DTE to the CTS pin of the other DTE, we can simulate this handshake.
Also, it is common convention for many DTE devices to assert the DTR signal when they are powered on, and for many DCE devices to assert the DSR signal when they are powered on, and to assert the CD signal when they are connected. By connecting the DTR signal of one DTE to both the CD and DSR inputs of the other DTE (and vice versa), we are able to trick each DTE into thinking that it is connected to a DCE that is powered up and online.
Virtual Null Modem (VNM) is an utility, which purpose is to emulate one or more RS232 serial ports connected via virtual null-modem cable. Otherwise, you can create any number of pure virtual serial ports in your system (COM10, COM11, COM255 etc), that will be connected to each other via virtual null-modem cable.
If you have two applications you want to connect to each other using serial ports you need a null modem. A null modem is bascially a cable to connect two serial ports to each other. Normally you need two computers or two physical ports on one computer to achive this. Using Virtual Null Modem software you can emulate the null modem and run the two applications on the same computer without any additional hardware.
You can create two virtual serial ports: COM10 and COM12 and connect two different applications to them. Everything, that application #1 will send to COM10 will be received by application #2 at COM12, and all that application #2 sends to COM12 will be received by application #1 at COM10.

Lightning Protection Association of India
PUSHING FORWARD MODERN LIGHTNING PROTECTION TECHNIQUES IS L.P.A.I.’S GOAL.
Burj Khalifa , Dubai has its tip protected by an ESE Lightning Protection system
A lightning protection system is designed to protect a structure from damage due to lightning strikes by intercepting such strikes and safely passing their extremely high currents to ground. A lightning protection system includes a network of air terminals, bonding conductors, and ground electrodes designed to provide a low impedance path to ground for potential strikes. Different solutions are currently available to the world. ILPA strongly believes in the most simple, efficient and modern device used to protect people and buildings from lightning strikes : the Early Streamer Emission (ESE) lightning conductor.
EARLY STREAMER EMISSION
If a lightning rod has a mechanism producing ionization near its tip, then its lightning capture area is greatly increased. At first, small quantities of radioactive isotopes were used as sources of ionization between 1930 and 1980, later replaced with various electrical and electronic devices. According to an early patent. Since most lightning protectors’ ground potentials are elevated, the path distance from the source to the elevated ground point will be shorter, creating a stronger field (measured in volts per unit distance) and that structure will be more prone to ionization and breakdown. You can find out more about the specifications of various ESE in our technical papers section.
Today, ESEs are widely used in different parts of the globe (see map below). In 1986, which is the first year of available statistics, number of ESE was 4 088 when in 1996 it was already a cumulated number of 112 412 units. The last 35 years have shown that ESE air-terminals are efficient and that the ESE solution is a reliable solution for lightning protection.

Over the past decades, many post-translational modifications (PTMs), such as ubiquitination, phosphorylation, and acetylation, have been studied for their role in regulating cell signaling events that are key for all cellular physiological functions. Recent advances in mass spectrometry (MS) technologies have enabled measurement of protein levels as well as protein modifications across cancer. Most studies thus far have focused on a single type of modification in a specific tumor type. We seek to understand the joint underlying patterns of PTMs in molecular signaling pathways that are shared across multiple cancer types by studying changes in protein acetylation and phosphorylation. We are part of the NCI’s Clinical Proteomic Tumor Analysis Consortium (CPTAC) efforts in collaboration with Drs. D.R. Mani, Steven Carr, Lewis Cantley, and Li Ding, among others.
We previously developed innovative computational methods called CLUMPS (clustering of mutations in protein structures) that identifies significant spatial clustering of mutations within the protein 3D structure and surface (Kamburov, et al., PNAS 2015). The key advantage of CLUMPS is that it takes into account the 3D distance between amino acids and not just the 1D distance along the linear genome, and the fact that it uses homology modeling to map proteins to 3D structures. We are now applying a similar approach to identify clusters of altered PTM sites.

Every lighting system comprises of the load and the controller. The load is the lighting luminaire that will produce the illuminance while the controller is the device that will adjust the loads to provide output. Controllers must be compatible with the load they are controlling.
Lighting controls are required to be properly designed to save a lot of energy, improve the lighting effects, and extend the life of lamps or ballasts.
Electrical building services engineers are required to consider how they are to be deployed in a project and how they will interact with the lighting luminaires in providing a desirable lighting response.
Types of Lighting Control System
1- Individual Lighting Control System: This is a lighting control system in which the controller is directly connected to the lighting luminaires or group of luminaires in a single space.
2- Network Lighting Control System: This is a lighting control system in which a group of individual controls is linked to a centralized controller. This gives the opportunity of controlling multiple spaces from a single point without interfering with the individual controls.
3- Preset Lighting Control System: This is a lighting control system that allows setting lighting luminaires at a preferred set called Scene. The scenes are saved and reviewed by any form of controller based on a limited number of configurations.
Classification of Lighting Controls Based on Interaction
Lighting controls continue to evolve due to the increasing demand for energy savings, better lighting effects, and extending the life of lamps. They can thus be classified based on their interaction with the building lighting system into:
1- Manual Lighting Control which are wired lighting controllers used in controlling individual or groups of lights by hand.
2- Automatic Lighting Control which is a lighting controller used in controlling individuals or groups of lights automatically mostly by sensors and relays.
Classification of lighting Controls based on the response
As home occupants’ demand for comfort and flexibility keeps increasing, lighting controls can be designed to satisfy occupant needs by the use of efficient lighting controls. The common lighting controls based on their reactions to luminaires can be classified into:
1- Direct Query Lighting Controls are binary lighting controls. They are mostly used to turn the lighting circuit ON/OFF.
2- Dimming Query Lighting Controls are the 4bit lighting controls. These controls do have the ability to adjust and adapt the luminaires lighting levels gradually by either darkening or brightening the fixtures.
Some controls can operate on mains voltage, while others are low-voltage (DC) powered.
Types of Lighting Controls
All lighting controls have their advantages and disadvantages, they also help to save a lot of energy, creating better lighting effects and extending the life of lamps. We are going to look at all the types of lighting controls that are used in the building services industries:
1- Standard on/off switches
4- Timer light switches
5- Sensors (Automatic)
6- Keypads, Touch panels, voice, and mobile devices
Standard On/Off Switches
Standard on/off switches also called the manual switches are forms of a direct query lighting control system. They are cost-effective and also the most common types of the control system in the construction industry with an amperage rating of 5A to 15A.
Standard on/off switches exists in different varieties which include the Bed Switch which is a hanging type of switch used with bed lamps, the Flush Switch which is the most common type and is fixed in walls, or the deprecated tumbler switches common in old homes.
These types of lighting controls can exist as a single unit called A One Gang Switch having a single rocker on them, or as a combined two-unit generally called Two Gang Switch, and a combined three-unit called the Three Gang Switch. The Four Gang Switch is also available but is rarely used because of the ambiguity in identifying each gang designation.
Moreover, when Standard on/off switches is connected to an electrical lighting circuit, they can be connected as a Single-way pattern when they control the luminaire from a point, or as a Two-way pattern when two switches control a single lighting circuit from different points. This pattern is mostly implored in stairways, lobbies, or halls as the luminaire can comfortably control from any of the entry. They can also be connected to a circuit in a Three-way or Intermediate pattern when three switches control a single lighting circuit from a different point.
Dimmer lighting control is a form of Dimming query lighting control system. They are less common compared to the Standard ON/OFF switches but are of greater comfort as illumination from the luminance can be set to a comfortable or mood level. They also provide occupants with the flexibility to instantly change the characteristics of space to make it more comfortable and productive. This thus protects the occupant from the glaring effect even if the project is poorly designed.
Relay lighting controllers are sophisticated low current controllers that can interact and relate to lighting luminaires in different ways. They exist mostly in panels (Lighting Control Module) managing a large group of luminaires and lighting circuits by triggering a number of an event at specific times or under certain load conditions. This thus allows luminaires to be controlled either by adjusting or by direct querying method.
Relays also provide the ability to control lighting luminaires by the use of Infrared Remote control or automatically based on pre-programmed function.
They also make lighting integration easier for automation, other building systems, and green buildings system as only the relay circuit is required to be connected to the network.
Timer Light Switches
Timer light Switches are forms of automatic direct query lighting controllers with a built-in time clock. These switches control luminaires based on preset time or times at preset intervals. These types of switches use either a programmable electronic timer or mechanical strings to operate.
They are mainly useful for routine applications such as the security lighting which are only to be ON during the dawn and to be OFF within a pre-set time of the day.
Sensors are automatic lighting controllers based on presence (Presence sensors) or the environment illumination level (Photosensor).
Presence sensors as the name suggest are automatic lighting controllers based on the presence of a temperate body. They thus send an impulse to their connected lighting circuit(s) a body that comes into their target monitored area. They are also of different types especially based on the technology they use to operate.
The Passive infrared sensors (PIR) is a form of Presence sensor solemnly designed to detect heat-emitting body such as human, animal, cars, etc by measuring the changes in the infrared level emitted by the surrounding object. Ultrasonic sensors emit an inaudible sound pattern that can be disrupted by any moving object. The Dual-technology presence sensors use both the PIR and Ultrasonic technologies to avoid false triggering.
The motion sensor is also a type of presence sensor common in the industry. These sensor types respond to any moving object mostly by a set sensitivity level making them very useful for utility and security lighting.
They are also mostly installed at the wall corner or ceiling spot of the ceiling, and Engineers are required to consider their coverage patterns and width while deciding the best fit for a project.
Photosensors are also known as Light-level sensors because they depend on the presence of light in the space. The most common types are the LDR based sensor that has the ability to changes with the light intensity that falls upon them. This thus gives the ability to use them as switches or for maintaining the desired light level by providing a smooth transition of the luminaire as daylight increases or decreases called daylight dimming.
Keypads, Touch Panels, Voice and Mobile Devices
Keypads, Touch panels, and mobile devices are been implemented as lighting control in modern buildings. Building occupants that do demands flexibility and an intelligent lighting system may decide to deploy them into the home automation system.

From the moment we are born (as well as our genetic baggage!) we have a wide variety of experiences. Every emotional shock in our lives, the accumulation of stress, or traumas create psychic “turbulence” that diverts the normal processing of information by the brain.
The system uses sensors to measure brain activity (eeg), to detect irregular electrical activity or these “turbulences” and informs the brain in return so that it can correct itself.
Music or a correlated sound is emitted throughout the session. As soon as the system detects the onset of turbulence, it briefly interrupts the sound. This micro-cutting, which creates an unexpected and significant effect for the brain to a surprise effect that will trigger a whole series of reactions and in particular the reorganization of the connections between neurons, is also called self-regulation.
The repetition of these brief interruptions helps the brain to function more harmoniously and to optimize its potential, which results in functional improvements, for example on the cognitive, emotional, psychic, behavioral and even motor levels. The brain, thanks to its plasticity and learning mechanism, reorganizes and regulates itself as well as possible. It is therefore the brain itself that does the work of correction and improvement.
In short, the brain, thanks to its plasticity and its learning mechanism, reorganizes and regulates itself as well as possible.


In this photo, a brilliant Iridium flare blazes in the sky high above the henge.
Iridium flares are caused by particular communication satellites that have large, mirror-like antennas that sometimes reflect sunlight directly onto the Earth below. If the angles are just right, the reflected sunlight can be very bright in this case, it was magnitude -8 many times brighter than the brightest stars. The positions of Iridium satellites are precisely known, so it's possible to predict when and where a flare will be seen.
The flare is in between the constellations Draco and Hercules, and the bright star between the flare and the henge is zero magnitude Vega.


µCT stands for micro-computed tomography – or X-Ray imaging in three dimensions. Similar to hospital CT scanners, these devices are suited for preclinical X-Ray imaging with resolution to the sub-micron scale. Unlike clinical CT scanners where the patient remains still while the scanner images around them, the µCT uses a translatable stage to rotate the sample through hundreds of angular views while the computer computes a stack of virtual cross section slices through the object.
The result is a high-resolution 3d stack with resolution down to 0.5µm for sample sizes up to 75mm. The µCT is a fantastic tool for phenotyping mice, imaging ex-vivo tissue such as lung or even imaging through intact bone.
See our ‘Available Instruments’ list (above right) for details about our μCT scanner.

Want to stay warm without cranking up your thermostat? Space heaters can be a great solution. But should you plug them into an extension cord or power strip?
If you’re like most homeowners, the answer is probably yes. Extension cords and power strips give you the flexibility to place heaters exactly where you need them.
However, this common practice is extremely dangerous and can cause electrical fires or electrocution.
In this post, I’ll explain:
- Why you should never use an extension cord or power strip with a space heater
- Safety tips if you have no choice but to use an extension cord
- How to choose the right heavy-duty extension cord or power strip if needed
After reading, you’ll understand why direct wall outlets are so important for space heaters – and how to use them safely if you must rely on extension cords in a pinch.
Reasons You Should Never Use an Extension Cord or Power Strip
1. Incapable of handling high current
One reason why you should never run a space heater on an extension cord is the issue of overheating, which can cause a fire. Generally, most extension cords and power strips are designed to handle lower amounts of current (Amps). They typically have ratings between 10 to 15 Amps.
On average, a space heater draws around 1,500 Watts of power and 12.5 Amps or more. The current will increase when you plug an electric heater into an extension cord that has a lower rating than the heating appliance.
High current can cause the wires of the extension cord or power strip to overheat and melt the insulation. If not addressed immediately, overheating in the wires can lead to a fire. Also, exposed wires present the danger of an electric shock.
2. Extension cords cause efficiency loss
Efficiency is essential when it comes to heating a room in your home. You want to spend less while getting the most heat from your space heater. But when you run a space heater on an extension cord, the efficiency of the heater tends to decrease.
Depending on their gauge, an extension cord or power strip can only deliver power to an appliance at a specific wattage and distance.
An electrical heating appliance relies on a good power source that supplies sufficient energy. The wires on extension cords generate electrical resistance. This reduces the amount of power delivered to the connected appliance.
And thus, it is best to plug a space heater directly into an electrical outlet to reduce power loss.
3. Tripping, fire, and other hazards
The extension cord you’re using to run a space heater could get in someone else’s way. Cords lying across a room are potential trip/slip/fall, fire ignition, and electric shock hazards.
Kids and pets are most likely to trip the cables. Moreover, your space heater could break after getting tipped over.
The impact of a space heater falling over can cause damage as it hits the floor. It might also melt or burn something.
Today’s space heaters do come with some sort of tip-over protection. It is a feature in the device that automatically shuts off the heat after getting tipped over. However, the space heater can still burn something if it hasn’t cooled yet.
Pay special attention if your space heater doesn’t have an automatic shut-off feature. It can leave a dark, burned stain if it accidentally falls over your carpet. Or worse, it could potentially start a fire.
Can You Use a Heavy-Duty Extension Cord With a Space Heater?
Do not use an extension cord or power strip with your space heater. Space heaters are mostly responsible for home heating-related fires. They are the 2nd-leading cause of home fires in the U.S.
However, if you have no other option but to run a space heater on an extension cord, you must get a heavy-duty one. Heavy-duty extension cords should have the same or greater wire gauge than the standard house wiring.
In North America, heavy-duty extension cords typically have a wire gauge of #12. In Asia and Europe, the #14 gauge is considered heavy-duty. It is known to be ideal for the 220-240 volt single-phase wiring used in those regions.
Space Heater Extension Cord/Power Strip Safety Tips
Here are some safety tips when you want to use an extension cord or power strip with your space heater according to the ESFI:
- Make sure to choose a space heater that comes with a label showing that it has been tested and listed by a recognized testing laboratory.
- If you just purchased a space heater, always read the instruction manual and look for warning labels before operating the device.
- Examine your device and look for cracks and loose connections. Do not use the device if you see any frayed, worn, or damaged components.
- Do not leave the device unattended. Always turn it off before leaving the room.
- Remember, space heaters are used only to provide supplemental heat. Never use it for activities other than heating a room such as cooking, drying your clothes, or warming your bed.
- Keep your space heaters 3 feet (1 meter) away from flammable materials such as papers, clothing, rugs, etc.
- To avoid a tripping hazard, do not place space heaters in areas of your home where foot traffic is high.
- Whenever possible, plug your space heater directly into an outlet. Also, make sure no other appliance is plugged into that same outlet.
- Avoid placing space heaters that make them easy to tip or fall over such as furniture, tables, cabinets, carpets, rugs, etc.
- Make sure that the extension cord or power strip you are using has a label with a wattage rating on it.
- The wattage rating of your extension cord or power strip should meet or exceed that of your connected appliance or space heater.
- Never use damaged cords or power strips especially when it feels hot or when the wires are exposed. Overheating can lead to a fire and touching even just a single strand of energized wire can cause an electric shock.
- Purchase extension cords and power strips that are approved by recognized testing organizations such as UL, ETL, or CSA.

WebGIS is a forecasting and warning system for communities at risk that requires the combination of data and forecast tools. Coordination and data sharing, moreover, can significantly increase the amount of information available. Thus, it is crucial to acquire the full range of data and information recorded and produced by different sources encompassing different space-time scales.
The very purpose of the WebGIS platform is to facilitate the joint management of events and operations running in real-time on cartography. This includes also the analysis of geographic information of the observed territory. Each resource inside the system is designed to be analyzed, shared, and reused independently for each new event.
The WebGIS platform is designed for comprehensive disaster and risk management combining information from threats and vulnerabilities. It collects and systematizes recorded data and produces value-added elaborations: forecast models and remote and in situ observations, integrated with vulnerability and exposure data to produce real-time risk scenarios.
The platform currently focused on some of the selected areas, but the database will be enlarged to encompass all Programme Countries.

Definition: MRI stands for magnetic resonance imaging, which is a type of scan that uses radio waves, a powerful magnet, and computers to show what is going on inside your body. The signal types that are produced by normal and abnormal areas are different and help the radiologist tell the difference between normal and abnormal anatomy. This type of scan produces images that are similar to a CT scan but the technology does not use radiation or x-rays. In some places of the body it can be more accurate and precise. Usually it is used for brain, spine and joint imaging. However it is sometimes helpful in the pelvis when looking for details in anatomy that a CT scan or ultrasound may not provide.
The CT scan was not clear so an MRI was ordered to see if muscle and nerves in the pelvis was involved by ovarian cancer.


BT develops sailboat innovation at a rate of knots
11 November 2016
BT is developing ground-breaking technology that could help the Land Rover BAR team land the America’s Cup.
The company has teamed up with software firm Coderus to work on a solution to one of the biggest technology challenges in America’s Cup racing – providing fast and accurate tactical information to crews working at the very limits of their capacity.
The America’s Cup, with its extraordinary physical demands, high speeds and extreme environments, requires an ingenious approach to provide infallible technology to crew members.
BT’s solution combines the gigabytes of data from the hundreds of sensors onboard with sophisticated display techniques, and cutting edge analytics to help the race team make the right decision in a split second, the tiny margin between victory or defeat.
Technology as important as skill
Matt Lawson, head of Applied Technology Centre at BT, said: “We’ve joined forces with Coderus to develop technology that we hope will set the Land Rover BAR team apart from its competitors. The America’s Cup is as much about technology as it is skill. It’s developments like the one we’ve been innovating with Coderus that we believe will truly make a difference.”
BT is the Land Rover BAR team’s official technology in sustainability partner and a member of its Technical Innovation Group.
The company has a long-standing relationship with Coderus which is based at Adastral park in Suffolk.
Extensive testing and development of the solution has taken place at the home of Land Rover BAR in Portsmouth and has already been used during practice at the Louis Vuitton America’s Cup World Series in France.
The America’s Cup is the oldest sports trophy in the world. Its rules prevent full use of tactical aids until the America’s Cup qualifiers begin in Bermuda next May.
Mark Thomas, CEO, Coderus said: “Naturally, we are delighted at having been asked to work on this. The project itself is extremely exciting and we are looking forward to being able to share more about what we’ve been doing in the coming months. It is also a huge honour to play a small part in representing Great Britain at this prestigious event.”


The popularity of mobile phones has led to many other discoveries. Aside from text messaging and videoconferencing, GPS mobile phones are also introduced in the market as an advance tracking feature. GPS stands for Global Positioning System, a technology that helps people track locations. Having this kind of technology is tantamount to having a virtual map through GPS mobile phones. Instead of using GPS as separate device or built-in car accessory, GPS mobile phones help increase mobility and efficiency.
WHAT ARE GPS MOBILE PHONES
The GPS satellite was first developed as part of a military project until it became a more popular technology with the emergence of GPS receivers. These receivers come in different shapes, sizes, and designs. Others are used as a "hand-held" device, while some GPS receivers fuction as a built-in feature, especially in cars. GPS mobile phones receive signals from dozens of satellites around the globe.
But why use a separate GPS receiver if GPS mobile phones can offer you almost the same benefits including portability? GPS mobile phones function as a tracking system that you can use whenever you're lost or need direction in and around the city. GPS mobile phones are best used during emergencies or when you need road assistance. The only downside is that some GPS receivers may offer more advanced features such as voice alerts or better control system. GPS mobile phones, on the other hand, are used based on the control and activation system of the mobile technology provider.
Tracking other mobile phone users may also be limited when using GPS mobile phones. In most cases, mobil phone users need to have the same network provider and GPS-compatible phones.
WHAT ARE THE ADVANTAGES IN USING GPS MOBILE PHONES
PDAs and high-end mobile phones were the first to feature the GPS mobile technology. Aside from advanced messaging functions, these mobile handsets also featured acces to the Internet. These advancements led to the development other cool add-ons such as 3G videos. With these, it may be safe to say that mobile phones are not only used for wireless communication but also have an entertainment value attached to them. With GPS mobile phones, more people get convenient acces to information and quick responses.
Primary benefits of GPS mobile phones include:
- Functionality. Despite changing weather conditions, GPS mobile phones can still offer navigation features.

By leveraging IP geolocation databases, businesses can identify the physical location of an IP address and find the city associated with it. This information can help businesses take actions to improve network performance. In this blog, we will explore the significance of IP geolocation data in network infrastructure and performance management, along with the best IP geolocation databases available in the market for finding the city by IP address.
What is IP Geolocation Data?
IP geolocation data refers to the physical location of an IP address on the internet. It involves mapping an IP address to a physical location, such as a country, state, city, or even a specific street address. This data is gathered using various techniques, including GPS, Wi-Fi triangulation, and cell tower triangulation. IP geolocation data is an essential tool for businesses that rely on the internet for their operations, as it enables them to track and monitor network performance across multiple locations.
Find City By IP Address
One of the most common uses of IP geolocation data is to find the city or region associated with an IP address. This information can be used to track user behavior and target specific locations for marketing purposes. For example, an e-commerce website might use IP geolocation data to display products or services that are relevant to the user’s location. Additionally, IP geolocation data can be used to detect fraudulent activity, such as when a user attempts to make a purchase from a location that does not match their billing address.

There are several IP geolocation databases available in the market, each with its own set of features and benefits. Some of the most popular IP geolocation databases include MaxMind, IP2Location, and GeoIP. These databases offer accurate and reliable data that can be used for a variety of purposes, including network infrastructure and performance management. When selecting an IP geolocation database, it is important to consider factors such as accuracy, reliability, and ease of integration.
Benefits of IP Geolocation Data in Network Infrastructure and Performance Management
Now that we have a basic understanding of IP geolocation data, let’s discuss the benefits of using this data for network infrastructure and performance management.
Network Monitoring and Troubleshooting
IP geolocation data can be used to monitor network traffic across multiple locations, enabling businesses to identify and troubleshoot performance issues quickly. By tracking the physical location of an IP address, network administrators can identify patterns and trends in network traffic, such as peak usage times or locations with the highest traffic volume. This information can be used to optimize network infrastructure and ensure that resources are allocated where they are needed most.
User Experience Optimization
IP geolocation data can also be used to improve the user experience by delivering localized content and services. By identifying the user’s location, businesses can deliver content that is relevant to their interests and preferences. For example, a travel website might use IP geolocation data to display flights and hotels that are available in the user’s location. This not only improves the user experience but also increases the likelihood of conversion.
Fraud Detection and Prevention
IP geolocation data is also an effective tool for detecting and preventing fraudulent activity. By tracking the physical location of an IP address, businesses can identify suspicious activity, such as multiple account logins from different locations or high-value transactions from unexpected locations. This information can be used to flag potential fraudulent activity and take appropriate action to prevent it.
Compliance and Regulatory Requirements
Many businesses are required to comply with regulatory requirements related to data privacy and security. IP geolocation data can be used to ensure compliance with these requirements by tracking the physical location of data and ensuring that it is stored and processed in accordance with applicable laws and regulations.
The role of IP geolocation data in network infrastructure and performance management cannot be overstated. The ability to identify the physical location of network endpoints and find the city associated with it allows businesses to optimize network performance, improve security, and enhance the customer experience.

Have you considered playing a video from your computer or phone on your LCD screen to view your favourite movies? Since the Wi-Fi Alliance launched Miracast a few years ago, it is now possible to do so even without a wire.
A video played on a computer can be seen on another device, TV, or computer via Miracast. “HDMI over Wi-Fi” is another name for it. This article covers Miracast, including how to install Miracast on Windows 10 and how to troubleshoot any issues that may arise.
What Exactly is Mira?
Miracast is a wireless technology standard. It links a computer, laptop, tablet, or smartphone to a television, monitor, or projector. It was first featured in Windows 8.1, and it is now embedded into the majority of devices and systems.
You may use Miracast to mirror the screen of a PC or laptop onto a TV or projector without using any cables. Up to 1080p HD videos and 5.1 surround sound can be delivered in this manner, which is more than enough for in-house use.
How To Determine Whether or Not Your Device Supports Miracast?
Miracast is embedded into a lot of gadgets. You should double-check that your device is compatible. Follow the steps below to do so:
Step 1: Hit Windows key + R to open the Run dialogue box, then type “dxdialog” and press Enter.
Step 2: Choose the “Save all information” option and save the file wherever you choose.
Step 3: Go to the dxdiag.txt file, open it, and look at the Miracast status. “Available” will be written next to it if it supports it.
Miracast On Windows 10: How To Set It Up and Use It
Set up Miracast to use it if your device supports it. Follow the steps below to get started:
Step 1: Switch on your television or other display device. Connect a display adapter to its HDMI port if it doesn’t have built-in Miracast compatibility.
Step 2: Go to the Settings menu on your computer.
Step 3: Select Devices from the Settings menu.
Step 4: Select “Add Bluetooth or other devices” from the Devices section. Then choose your TV (or the adapter if your TV doesn’t have built-in Miracast functionality) from the list of supported devices.
Step 5: Once your Windows PC and TV are connected, configure them by hitting Windows + P and picking one of the choices.
As a result, it uses Miracast to connect your display devices.
In Windows 10, Miracast Isn’t Working
Despite the fact that Windows 10 ideally supports Miracast, you may encounter an error when attempting to utilise it. It’s possible that a “not supported” notice could show, or that the video on the receiving device will be silent.
It could be due to out-of-date drivers or a non-compliant adaptor. In this scenario, try the following options:
1. Update Your Drivers
Because of outdated drivers, the connection may not work. Check if your computer’s display and wireless drivers are up to date by going to Device Manager (Windows + X, then Device Manager). If not, use a driver update utility programme to update them (install them from online).
2. Use a New Adapter
Because many firms make display adapters, not all versions will work with your device or system. Attempt to use a different adaptor. The Microsoft Wireless Display Adapter is the finest solution.


What is a Dynamic & Condenser Microphone?
The most common dynamic microphone is the Shure SM57. This microphone is relatively inexpensive and extremely versatile in application. Nevertheless, we're not here to discuss particular microphones, we're here to examine what a dynamic microphone is in relation to transduction. A dynamic microphone converts sound into an electrical signal through electromagnetism. Dynamic microphones fall into two categories, moving coil and ribbon. The ribbon microphone, on a practical standpoint is viewed as a separate group of microphones even though it falls under the same category because both types use electromagnetism to transduce sound into electrical energy.
"Moving coil microphones are probably easiest to understand, because they are basically built like a loudspeaker: A coil is glued to the rear of a membrane, and there is a strong magnet surrounding this coil. When sound waves hit the microphone, the membrane moves to the rhythm of the sound waves, and the coil on its back moves along with it. The relative movement of the coil within its (stationary) magnetic gap induces a small signal voltage in this coil. There’s your microphone, a device that converts sound into an electrical signal. (a)"
These microphones work on the same principle of electromagnetic induction. Rather than using a membrane and coil they use a narrow strip of thin aluminum foil to transduce sound into an electrical signal. This design allows the microphone to follow the movement of the sound waves more accurately making it a much better replicator of sound. So if you're looking for a more analogous microphone, then ribbons are the way to go! However, ribbon microphones produce a much lower output and thereby contain a step-up transformer to increase the output voltage. Having a lower sensitivity to a sound source, ribbons also require a low noise preamp with lots of gain.
"Ribbon mics are very fragile and must be treated with great care. Another drawback is that the treble response of most ribbon mics is quite limited. Today, ribbon mics are used for special applications, only, where extended top end is not required, e.g. for guitar cabinets, or not wanted, e.g. to tame overly bright brass instruments. (a)"
The use of a stretched conductive membrane suspended above a fixed conductive plate, are two key components that make up the condenser microphone. This particular kind of microphone heeds great results when capturing sound. When variations in air pressure, otherwise known as sound, move the membrane closer or farther from the backplate, also known as the capsule, it varies the voltage and converts it into electrical audio.
"This is the major electromechanical contributor to the sound of the mic, as it is where acoustic energy is converted to electrical energy. This now electrical audio is amplified by an amplifier inside the mic which raises the electrical level of signal high enough and noiselessly enough to be sent to the mic preamplifier, another piece of gear required before it reaches line level and can be mixed or modified with signal processing. It is important to note that all three components — membrane, backplate and electrical amplifier — have a profound effect on the sound of a microphone. (b)"
Every microphone has a specific function, color, and distinct characteristic. Understanding microphones is essential in order to properly record music and speech. In this blog, we've only discussed a very small portion of the subject. For a more in depth look into microphone techniques, function, and design, ask Google. Google knows everything!

AUTOMOTIVE, 125°C OPERATION, 36 V INPUT, 1000 mA VOLTAGE REGULATOR
6. Overcurrent protection circuit
The S-19214 Series has a built-in overcurrent protection circuit to limit the overcurrent of the output transistor.
When the VOUT pin is shorted to the VSS pin, that is, at the time of the output short-circuit, the output current is
limited to 250 mA typ. due to the overcurrent protection circuit operation. The S-19214 Series restarts regulating
when the output transistor is released from the overcurrent status.
This overcurrent protection circuit does not work as for thermal protection. For example, when
the output transistor keeps the overcurrent status long at the time of output short-circuit or
due to other reasons, pay attention to the conditions of the input voltage and the load current
so as not to exceed the power dissipation.
7. Thermal shutdown circuit
The S-19214 Series has a built-in thermal shutdown circuit to limit overheating. When the junction temperature
increases to 170
°C typ., the thermal shutdown circuit becomes the detection status, and the regulating is stopped.
When the junction temperature decreases to 135
°C typ., the thermal shutdown circuit becomes the release status,
and the regulator is restarted.
If the thermal shutdown circuit becomes the detection status due to self-heating, the regulating is stopped and V
decreases. For this reason, the self-heating is limited and the temperature of the IC decreases. The thermal
shutdown circuit becomes release status when the temperature of the IC decreases, and the regulating is restarted
thus the self-heating is generated again. Repeating this procedure makes the waveform of V
into a pulse-like
form. This phenomenon continues unless decreasing either or both of the input voltage and the output current in
order to reduce the internal power consumption, or decreasing the ambient temperature. Note that the product may
suffer physical damage such as deterioration if the above phenomenon occurs continuously.
If a large load current flows during the restart process of regulating after the thermal shutdown
circuit changes to the release status from the detection status, the thermal shutdown circuit
becomes the detection status again due to self-heating, and a problem may happen in the
restart of regulating. A large load current, for example, occurs when charging to the C
capacitance is large.
Perform thorough evaluation including the temperature characteristics with an actual
application to select C

The S-19214 Series has a built-in inrush current limit circuit to limit the inrush current generated at power-on or at
the time when the ON / OFF pin is set to ON. The inrush current is limited to 400 mA typ. immediately after
power-on or for the internally set, predetermined time of 100
μs min. from the time when ON / OFF pin is set to ON.

A follow up to the previous post.
Another idea was proposed in the CIC Discord after I developed the prototype. An ongoing feature of the Wing Commander series are in-cockpit VDUs (Visual Display Units.) Essentially, they are small computer monitors inside your in-game cockpit that are used to give vital information to help you navigate the game and quickly access options while in combat. They might contain a systems damage readout, information on an enemy target, navigational data, or a short animation of your wing man’s communication to you in the form of a talking head.
Obviously such a thing would be a very cool feature for my previously mentioned external cockpit! I knew that the Arduino I used in my previous blog entry was capable of driving a color LCD so I began exploring how to extract such information from the game. The games run in DOSBox, which emulates the VGA graphics standard that was common in MS-DOS games of the era of their release. Though I didn’t have much experience with this exact kind of programming, I knew the basics of how it worked from a high level: by writing pixel color data to a reserved portion of memory, the graphics card would read this exact data back to display to the user’s screen.
Things were a lot simpler back then. The CPU would do all the work of rendering a bitmap and then write it to this reserved memory. Though different graphics cards would offer various features, the basics were the same throughout. I knew that DOSBox must provide a similar buffer of memory for its emulation. After all, the games themselves expect there to be a buffer of memory to write to, so it must be there somewhere!
I began by doing some research on how VGA worked so I could find the data that I needed to do this. I found a wonderful website maintained by David Brackeen called 256-Color VGA Programming in C that explained so many things in a wonderful mix of technical and abstract explanation! I genuinely would not have been able to complete this step of my project without his information.
I utilized DOSBox’s debugger to view the VGA buffer (known to be at the emulated memory address of 0xA000) on an in-game screen that I knew would remain static and not change. I then was able to return to this screen in the more common non-debugger version of DOSBox and use Cheat Engine to locate the binary data in the (non-emulated) memory of DOSBox itself!
The next step was to determine the custom palette that Wing Commander 2 uses. Again, David Brackeen’s site gave me a lot of information on how to program this. Unfortunately, I wasn’t able to easily determine where in memory DOSBox stores this information (although I’m sure it’s there somewhere.. It is a puzzle I am determined to solve!) I did come up with an alternate solution to the problem. I took a screen capture in DOSBox to a PNG file. Because PNG stores its palette information in the file itself, I could easily process this file using some convenient .NET classes to generate a reusable palette.
Armed with the memory address of the VGA frame buffer and the palette the game generated, I could now capture video directly from memory! I spent some time building a GUI in Visual C# to not only display these video captures, but also create a more comfortable user interface for connecting to the Arduino.
Obviously the next step would be to connect a color LCD to the Arduino and see how it works. However I haven’t yet acquired one to test. In theory, it should be able to work, though perhaps a bit slowly. The Arduino communicates with the PC over a serial connection, which is fairly slow compared to more modern technology. After doing some Googling, I was able to find that the Arduino should be capable of at least 1 Mbps, or approxmiately 125 kilobytes of data per second.
Each VDU ranges in size, depending on the ship you’re flying, but are at most 75×75 pixels, or 5.625 kilobytes each. If you have two VDUs, we’re looking at 11.25 kilobytes. The frame rate at 1 Mbps would therefore be around 10 frames per second for a live feed in a perfect world. In my research, I saw claims of up to 2 Mbps for the Arduino, but I’d have to get my hands on some hardware and do some more research to find out the capabilities.
I can’t thank David Brackeen enough for keeping this information available on the internet. MS-DOS programming is a bit of a historical artifact at this point but it’s great knowing that there are people out there keeping it alive for the rest of us.
The current source code for the Memory Reader GUI is available on my Github profile. As of this writing, I haven’t yet added the Arduino functionality to it but it will be a quick add via a commit within a day or two.


Until recently, the SSDs on the aspectra Shared ESX Farm were housed in the same storage as the HDD. The performance advantages of the SSD could therefore only be partially exploited. Thanks to the purchase of an all-flash array from Pure Storage, the IOPS could be significantly improved.
Very high availability and data security are of paramount importance. The storage consists of an active/active cluster with two locally separated arrays, which are redundantly connected to the ESX farm via a Fibre Channel SAN. In this context, redundant means that each array has two controllers, which in turn are connected to two SAN fabric (switches) via two FC connections each. This connection method is known as FC Uniform Storage Connectivity.
The synchronization of the data between the two arrays is done over the replication link. For this purpose, each controller hangs redundantly on an independent synchronization network via Ethernet.
Pure has introduced so-called "Pods" to simplify storage management. A pod is a management object that spans both arrays. It contains the actual volumes as well as the protection groups with the snapshot settings (interval and retention time). It is also possible to define a preferred array so that the VMs address their volumes on the nearest array if possible.
Each pod can be assigned a size that goes even beyond the physical capacity of all discs combined. Pure Storage Management manages the space occupied by the VMs and their snapshots, as well as the RAID configuration. A data reduction with different, combined methods increases the usable capacity. The data reduction factor depends on the application. In our setup in the server virtualization environment, a factor of 2.6 was achieved.
The failover mediator is a third-party system that must be placed in a separate environment. Pure offers the Pure Cloud Mediator as a service. It is also possible to install a mediator as an on-site appliance. The mediator monitors the arrays and decides which of the two arrays continues the service if the synchronization fails. This prevents a "split brain" situation.
The aspectra storage team has tested the various error cases in a laboratory environment. Failures of single controllers or an entire storage array as well as interruptions of FC connections or the synchronization network did not lead to any problems. The virtual systems continued to run without any interruption or data loss.
Only the simulation of a multiple failure was able to put the virtual servers into freeze mode. First the synchronization was disconnected and after a certain time an array (B) was switched off. The VMs were frozen and had to be restarted on array (A) with the data from the time before the synchronization failed.
Hardware failures are detected by the mediator and reported to Pure Support. They will automatically replace the hardware. The Pure-Support also reports to the hosting provider, if the replication link fails, for example. In the Pure Web Client there is a menu item for analysis functions. We have also tapped into the REST interface to monitor the storage in our SNMP-based monitoring environment. This API also uses the available templates for Zabbix, which we use in parallel.
