One of the challenges of analysing interferograms is distinguishing interesting, geophysical signals, such as earthquake or volcano deformation, from each other, and from atmospheric noise. Robust tests for the independence of geophysical signals are also important for establishing causal links between magmatic, hydrothermal and tectonic processes.
Independent Component analysis (ICA) is a computational signal processing method that decomposes a mixed signal into components that maximise signal independence in either space or time. This relies on the idea that as more and more independent signals are mixed together, their sum gets closer to a Gaussian distribution – so the parts of a mixed signal that are ‘interesting’ will be the least Gaussian. Finding these components is useful for analysing the relationship between the different deformation processes. Signals caused by the same process can be identified by searching for ‘clusters’ in the identified components. Real geophysical signals are very much more likely to cluster than atmospheric signals, so this is a useful approach both for distinguishing between true deformation and atmospheric noise and for analysing the relationships between geophysical signals.
I’m interested in the application of such blind source separation methods in volcanology, whether applied to InSAR, GPS, gas measurement etc., and would welcome any chances to collaborate.

Xbox 360 GPU; note the smaller eDRAM die to the left of the main Xenos die
The Xbox 360 is similar in form factor to its predecessor. It is slightly slimmer in every dimension, and the industrial design helps reinforce this impression; the Xbox 360 is white and slightly concave, whereas the original Xbox was black and noticeably convex. The Xbox 360 is also about 350 grams lighter than the original Xbox. Much of this savings in size and weight was achieved by moving the power supply out of the console proper; the power supply by itself displaces 1300 cubic centimeters.
The Xbox 360 hardware features brand new approaches to its design, including an entirely different multi-core central processing unit (CPU) named Xenon and the Xenos GPU with Unified Shader Architecture. Xenon is a custom triple-core PowerPC-based design by IBM as opposed to the Xbox’s Intel Coppermine-128 microprocessor. Each core of the CPU is simultaneous multithreading capable and clocked at 3.2 gigahertz.
In addition, while the first Xbox’s graphics processing unit (GPU) was produced by NVidia, the Xbox 360 uses a chip designed by ATI called “Xenos” (Developed under the name “C1”, sometimes “R500”). Xenos contains 48 unified shader units, which are capable both Vertex and Pixel shading operations in contrast of separate pipelines of current GPU design. The GPU package contains two separate silicon dies: the GPU proper and a eDRAM die for FSAA and post-processing. Heatsinks protect both the GPU and CPU of the console and the CPU heatsink uses heat pipes. The heatsinks are actively cooled by a pair of 60 mm exhaust fans that push the air out of the case.
Xbox 360 Bandwidth Diagram
The console features 512 mebibytes of 700 megahertz GDDR3 RAM, which is shared by the CPU and the GPU via the unified memory architecture. A 21.6 GB/s front side bus (aggregated 10.8 GB/s upstream and downstream) is also featured by the console. For network and peripheral device connectivity, the console has a built-in 100BASE-TX RJ45 ethernet port, suitable for connecting to Xbox Live, and three USB ports.
All games made for the Xbox 360 are required to support at least six channel Dolby Digital surround sound. Additionally, a wide array of standard and HDTV resolutions, up to 1920×1080 in interlaced mode, are supported by the console hardware. The Xbox 360’s optical drive supports a wide variety of DVD-ROM formats in addition to DVD Video, as well as most common CD-based formats. The option to apply a regional lockout to games is available to publishers. DVD region codes are always enforced. A 20 gigabyte detachable hard drive is available for game saves and downloads (included in the non-Core version of the console), as are small, portable memory cards.
Components and accessories
An Xbox 360 Wireless Controller
Up to four controllers are supported by the Xbox 360, in either wired or wireless forms, and there is an optional wireless force feedback racing wheel for racing games that can be purchased separately as well. The Xbox 360 connects to Xbox Live through a optional wireless network adapter on a home network through a wireless router, and the Universal Media Remote can be used to control several functions of the console including the Windows Media Center functions if connected to the network. Various other components for the console exist such as decorative faceplates to change the physical appears of the console, wired or wireless headsets for communication over Xbox Live, and a Xbox 360 branded webcam called Xbox Live Vision Camera. An add-on external HD DVD drive will be released holiday season 2006.
Thats the general knowledge. It was courtesy of Wikipedia.com and is subject to change. As of right now, my review is a 8/10!
Plenty of strong points, including Games, Xbox Live Arcade, HD Graphics, and some pretty good processing power. However, not perfect yet, as the HD-DVD drive which could have been used for games is on sale soon as an optional add-on to play HD-DVDs. It’s getting there, but it is pretty good. Seamless intergration of Xbox Live and Arcade as well as realtime Chat and up to 100 friends ViA live. WiFi is not out-of-the-box. It’s improving but not quite perfect.
8/10 Stars for the Xbox 360, By MICROSOFT


On Saturday, January 19, 2014, I submitted my first mobile app to the windows phone store. This app is a virtual odometer, using the user’s GPS coordinates to track how far they travelled between when they press the start and the stop measuring button. It gets a new GPS location every few seconds and uses the Haversine formula to calculate the distance between the users locations.
This app is for the Windows Phone, but I will soon make a version for Android and iOS. Now that I am done with Warthog Wars, I am going to start making mobile apps from now on.


Big data, no thanks
An alluring, essential talk called Big data, no thanks from James Bridle:
This is the first electronic general-purpose computer, the ENIAC, which was built at the University of Pennsylvania between 1941 and 1946. It was used extensively for Edward Teller’s early work on hydrogen bombs. The size of a couple of rooms, it had thousands of components and millions of hand-soldered connections.
The engineer Harry Reed, who worked on it, recalled that the ENIAC was “strangely, a very personal computer. Now we think of a personal computer as one which you carry around with you. The ENIAC was actually one that you kind of lived inside. So instead of you holding a computer, the computer held you.”


Scientists have discovered that the earth vibrates at a frequency of 7.83 hertz (the Schumann Resonance), which is about half of the lowest note (16.4 hertz) that can be produced on a large pipe organ. This extremely low frequency, along with its overtones, or harmonic frequencies, is created and maintained by lightning that continually strikes all across our planet—millions of times each day or dozens of times each second!
This “Earth’s Heartbeat” can be compared to, from a wave-based perspective, the broadcast or “carrier” frequency of a radio station. For instance, if I dial up a classical music radio station at the bottom of the FM radio dial, my ears will hear music from ONLY that one station—broadcasting in my area at 89.9Mhz. I can’t hear the hip-hop, country or other music coming from the many stations broadcasting above or on either side of it, even though they are there.
If you stretch this analogy a bit and compare our reality to a radio station, then you can conceptually understand how multiple wave-based realities can exist on earth by vibrating at different frequencies. Whether humans have an internal receiver that can detect these multiple realities, such as with mediums who claim to see and hear departed loved ones standing near them, is another discussion topic.

Electric cars have become increasingly popular over the last ten years, with both environmentalists and industries promoting them as a “greener” alternative to traditional cars that use fossil fuels. In fact, there are pros and cons to every invention, and as such some argue that lithium battery-powered cars may not be a solution to our environmental problems. Electric vehicles are a more recent development than lithium batteries themselves which have been around for much longer. Ten years ago, the market size for lithium batteries for power tools, for example, was $743 million US dollars. That same year, there were only about 50,000 electric vehicles sold with a global market share value of only 00.2%. Therefore, lithium mining for batteries has long since existed before extraction and production started for electric vehicles.
Another consideration regarding electric vehicles and the mining of minerals to create lithium batteries is an overall sustainable energy challenge. If all or most cars were to become reliant on the minerals needed for lithium batteries – lithium, cobalt, and zinc – the increased demand for these would likely be impossible to provide for the worldwide number of motorized vehicles. It takes 100 to 300 barrels of oil to manufacture a lithium battery that has the energy equivalent of 1 barrel of oil with a carbon debt rate ranging from 10 tons to 40 tons of CO2; and 500,000 pounds of materials are needed to make a single 1,000-pound battery. Although, battery recycling is sometimes available, lithium-ion batteries are typically built into the devices that they power making them hard to dismantle which is an important part of an efficient recycling process. Additionally, some recycling rules (specifically for the European Union) could have other negative consequences because electric car companies may be compelled to take them out of service early to meet a collection target even though they could still have useful battery life left. Issues such as these will need to be worked out as lithium batteries for vehicles become more prevalent time.
Although there are some negatives with lithium batteries, they are likely still a greener choice overall. Importantly, electric vehicles produce zero tailpipe emissions for the duration of their use, meaning there are no emissions coming directly out of the car which reduces the amount of pollution in that specific area. Research done by the European Energy Agency found that, including the electricity generated for charging an electric vehicle, the carbon emissions of that vehicle are around 17- 30% lower than driving a traditional gas-powered vehicle. Furthermore, electric vehicle manufacturers are using and improving eco-friendly materials to build lighter, more efficient vehicles allowing for increasingly efficient driving and further reductions in vehicles’ carbon footprints. Yet another study by the Union of Concerned Scientists found that regular gas-powered vehicles’ emissions surpass those of electric vehicles well-to-wheel (from mining to driving) emissions in just 6-18 months of operation.
Improving the sustainable production of lithium for everything from cameras to power tools and electric vehicles will be an important step moving forward. As the use of lithium batteries rises with the increasing popularity and availability electric vehicles, more studies and innovations will likely come to fruition including environmental mining protocols, increased battery efficiency/longevity, and improved battery recycling.

Acorn BBC Model B Faulty RAM Repair
About This Machine
The BBC Micro was a Microcomputer made by Acorn Computers; introduced at the end of 1981 as part of the BBC Computer Literacy Project, it was succesful both as home computer and in the educational market, with most schools in the UK using the machine for computing education. During the 1980s and 1990s, using a BBC Micro in primary school was the first experience of a computer for many people - including the author.
The Fault, Testing and Research
This example, despite being in immaculate physical condition, really wasn't happy when turned on; it seemed to put out a very bad video signal. Sometimes it appeared it was trying to work, but the picture would judder wildly.
Testing with an oscilloscope revealed the video signal looked ok, but on closer examination the vertical sync rate was 80Hz, obviously not to the liking of the 50Hz monitor!
A little research and head scratching later I figured out this is symptomatic of a RAM fault, causing the CPU to read garbage values that then get written into the 6845 video controller during boot, resulting in the weird output frequency. Further I came across a trick of moving a jumper on the motherboard (S25) to disable half the RAM, and this indeed worked, the machine operating happily and reporting itself with 16k of memory.
In this case this isolated the issue to the jumpered-out half of the RAM. Each 16k of RAM is made from 8 ICs, and likely not all of these were faulty - a way was needed to test them, ideally in situ as they are soldered to the board.
Fault Finding Hardware
If it was possible to swap the two RAM halfs, this would put the faulty chip into the video memory, where it would not crash the machine during boot.
Swapping the two RAM halfs electronically is possible - jumper S25 actually carries a signal used to select which half of RAM is operating, and inverting this signal as it passes through the jumper will swap the memory banks over.
To achieve this I created a small circuit board with a header that fits in place of the jumper.  The board carries a quad-nor gate used to invert the signal  The jumper header does not carry a +5V power line so a flying crocodile lead was used to reach the +5V rail on one leg of a nearby resistor. The circuit board had to be carefully designed to fit amongst the components surrounding the jumper header; note in the pictures I hung a supply bypass capacitor off the solder side of the board.
With the inverter circuit in place, the machine booted up and repored a full 32k of memory - or tried to, the message on screen was a little garbled due to using the faulty IC for video memory - made worse by booting up in Mode 7.
Changing to a bitmapped graphics mode and typing demonstrated the effect of the bad memory. Typing in one location on screen, multiple parts of the screen were written to - clearly writes to the bad IC were incorrectly happening to multiple locations at once.
Fault Finding Software
With the fault safely confined to video memory and the machine now booting, I worked on writing a BASIC program to run on the machine that could test the RAM by writing and reading it strategically to figure out which IC is faulty.
A listing of the program is given here in case it is of use. See the notes section for an explanation of how it works.
10 MODE 3 : H%=61 : REM - MEMORY SWAPPED H%=61 - NOT SWAPPED H%=53 20 Z% = ABS(RND) : A% = RND(-Z%) 30 FOR A% = 16384 TO 32764 STEP 4 : !A% = RND : NEXT 40 A% = RND(-Z%) 50 FOR A% = 16384 TO 32764 STEP 4 60 R% = !A% : U% = RND : IF R% <> U% GOTO 80 70 NEXT : GOTO 20 80 E% = R% EOR U% 90 FOR X% = 0 TO 30 : IF E% AND 2 ^ X% GOTO 110 ELSE NEXT 100 X% = 7 110 CLS : PRINT "FAULT IN IC"; H% + X% MOD 8 120 FOR A% = 1 TO 12000 : NEXT : RUN
Note the REMark on line 10 - it is not necessary to type in the REM part of the line, but it serves to draw attention to the H% = 61 assignment immediately before it, which must be changed depending on whether the memory is swapped around with the inverter circuit, as this affects which RAM IC will be identified as faulty.
As with most BASIC dialects of that era, it is possible for brevity to type the program into the machine without any spaces; indeed doing so will make it run faster. The code is presented above with spaces to make it easier to read.
The program is short enough to key into the machine fairly quickly (I did it several times without getting bored). When reading it off the screen to verify what's been typed, care must be taken if trying to see through any messed up pixels due to the bad memory.
The program runs and reports IC62 is faulty.
Breif attempts at desoldering the RAM IC made it clear this was not happening, making it necessary to resort to violence. Out came the dremel and I carefully cut all the legs of the IC close to it's body. With the body removed, each individual leg was be desoldered while pulling on it from the component side of the board. This minimised damage to the PCB by reducing the amount of heating required.
With the faulty IC removed and the board cleaned up, fitting a suitable IC socket and populating it with a new chip was the easiest part of the whole project.
After replacing the single IC and returning the jumper to normal, the machine once again ran happily with it's full 32k of memory.
The BBC Model B uses 16 individual DRAM (dynamic RAM) ICs to make up it's 32kB of RAM. Each IC stores a single bit's worth of memory for each of 16k addresses - requiring 8 chips for each 16kB of RAM.
The lower cost Model A left out half of these chips, and used the jumper used here to prevent the machine trying to access the non-fitted ICs.
Various DRAM ICs may be found in the BBC Model B; my example was originally fitted with HM4816AP-11 parts, and the replacement I sucessfully used is a MB8118-10.
Moving the jumper causes the computer to use the 'upper' half of RAM, ignoring the 'lower' half, which in this case was where the fault lay. If the fault appeared in the 'upper' half of RAM, which is used primarily for video data, it would not cause the computer to crash during boot, although it may cause inteference on screen.
The 16k jumper position merely ties the signal to the RAM low. The 32k position allows through a signal from the processor allowing it to chose between the first and second 16k of memory. Inserting a circuit to reverse this signal swaps the two halfs of RAM and moves the fault from the critical lower half to the upper half.
The connections on the S25 jumper header are:
North Output from IC28 (connect to input of the inverter) Center Input to IC45 (selects RAM bank - connect to output of the inverter) South Ground
South is towards the keyboard; north is away from the keyboard.
I used a quad-NOR gate IC as this had the most favourable orientation of input and output pins amongst the ICs I had to hand. Only one of the gates is used, configured as a simple inverter, the remaining gates have their inputs tied to the nearest power rail and their outputs open.
I initially tried to make a simple single transistor inverter, but for whatever reason the circuit was not fast enough. The computer did boot but the screen only displayed colourfully garbled mayhem.
How the program works:
Resident integer variables are used throughout to maximise performance and minimise the amount of typing (these are denoted by a single letter followed by a % symbol).
Line 10 sets video mode 3, which uses 16kB of memory and therefore uses all of the upper half of RAM for the screen. This prevents BASIC from trying to use any of the faulty memory and allows us to write all over it during testing.
Line 20 randomly chooses a seed value (kept in Z%) and then seeds the random number generator with it. The RAM is then filled with radomly generated data (FOR loop on line 30). Since the Beeb uses 32 bit integers, we can actually work through memory four bytes at a time (STEP 4) which makes things faster.
The random number generator is re-seeded (line 40) with the same value chosen on line 20; it will thus reproduce the series of random numbers it has just generated.
Lines 50-70 go back through memory, comparing the values read to the re-generated random sequence that was stored.
When an error is detected, we jump to line 80, where an exclusive-or function is used to detect which bits of the four bytes have been changed. We then loop over each of the bits (line 90), and jump to PRINT the result when we find a changed bit. Thankfully the component numbers used for the RAM ICs are laid out sequentially, making it easy to 'calculate' which IC has the fault.
The final line of the program creates a delay of several seconds so the result can be read, before returning the beginning to repeat the test (if multiple ICs have failed, a different result might occur each time).
While the program is running, the screen is seen filling up with random black and white pixels, followed by a pause while they are read back and compared. If there are no faults, after the pause, no message is displayed and the screen will be written over again with a new random set of data.
The first line of the program sets the variable H%, and must be changed depending on whether or not RAM has been reversed as described in this post. When RAM is not reveresed (the jumper in it's standard position), ICs 53 through 60 are tested - when RAM is reversed (jumper replaced with an inverter), ICs 61 through 68 are the ones being tested.
The location of the fault can be verified by very careful examination of which pixels of each character are impacted by glitching. In this case, a fault in IC62 makes sense as this is the second least signficant bit, and in Mode 3, errors occur in what looks like the second pixel from the right in each character.
I have since come across a similar project where the author experienced an analogous story arc.


Like many other countries in the world, Switzerland faces challenges (e.g., land management, environmental degradation) caused by increasing pressures on its natural resources. These challenges need to be overcome to meet the needs of a growing population. Switzerland is acknowledged as the water reservoir of Europe. While its territory represents four thousandths of the continent's total area, 6% of Europe's freshwater reserves are stored in Switzerland.
Snow is one of the most relevant natural water resources present in nature. It stores water in winter and releases it in spring during the melting season. Monitoring snow cover and its variability is an indicator of climate change and identification of snowmelt processes is essential for effective water-resource management.
Remotely-sensed Earth Observations (EO) data acquired by satellites are helpful to monitor snow conditions through time. Synthetic-Aperture Radar (SAR) images are effective and robust measures to identify meltingsnow, whereas optical data are able to identify snow cover extension.
Earth Observations Data Cubes (EODC) are a new paradigm revolutionizing the way users can interact with increasingly freely and openly available EO data. They minimize the time and scientific knowledge required to access, prepare and analyze large volume of data having consistent and spatially aligned calibrated observations.
Switzerland is the second country in the world to have a national-scale EODC. The Swiss Data Cube (SDC – https://www.swissdatacube.ch) is an initiative supported by the Federal Office for the Environment (FOEN) and developed, implemented and operated by the United Environment Program (UNEP)/GRID-Geneva in partnership with the University of Geneva (UNIGE). The objective of the SDC is to support the Swiss government for environmental monitoring and reporting as well as enable Swiss scientific institutions to fully benefit from EO data for research and innovation. Currently, the SDC contains 33 years of Landsat 5,7,8 (1984-2017) and 2.5 years of Sentinel-2 (2015-2017) optical Analysis Ready Data over Switzerland (total volume: 3TB; 110 billion observations).
Recently, UNIGE has developed a new algorithm using the SDC to map snow cover extension. Preliminary results have shown a clear decrease of snow cover over the Alps in the last 30 years. However, to provide an integrated and effective mechanism to monitor snow cover and its variability, SAR data are missing and impeding identification of snowmelt processes. A valid source is the European Space Agency (ESA) Sentinel-1 high-resolution C-band SAR satellite.
Consequently, the aims of this project are: (1) to develop a methodology for generating and ingesting Sentinel-1 Analysis Ready Data into the SDC; (2) improve the Snow Observations from Space (SOfS) algorithm to identify snow melted and iced areas; (3) generate time-series of 2D composite backscatter products over Switzerland; and (4) explore the potential of SAR/optical data fusion techniques as well as additional SAR data sources.

Preventing a severe disruption of leading scientific research
Weizmann Institute of Science, one of the world’ s leading multidisciplinary research institutions in natural and exact sciences, engaged RodRadar to support its sub-contractor in safely placing a 2m-diameter drainage line across the institute’s entire campus. In addition to detecting all the underground utilities previously mapped by the contractor’s surveyor, the LDR technology also exposed two unmarked utilities, a fiber-optic cable and a live powerline. This prevented potentially severe disruption to the institute’s scientific research, as well as mitigating the clear safety risks.
Lately, we have suffered a lot from electrical, fiber-optic and other infrastructure failures, which has significantly and negatively impacted our scientific activities. With RodRadar’s LDR technology, we discovered that we can safely execute an infrastructure and development project without disrupting our research and educational work.


Viking as a Stand-Alone Energy Solution
The Viking wind turbines are compatible with stand-alone systems (also called off-grid systems), where the turbines deliver the energy production directly to an independent unit and are thereby not connected to the electrical grid.
A stand-alone energy solution means that the wind turbines can be placed in areas, where there is no access to an established electrical grid or at places, where the coupling to an electricity supply meter and any added subscription is economically unsustainable.
Instead of connecting to the electrical grid, the production from the wind turbines is stored directly in battery banks or the turbine runs parallel with a diesel generator. From here the electricity will be converted so the energy can be used for various electrical devices.
Furthermore, the Viking VS wind turbine can do without a battery bank and a diesel generator by adding a UPS (uninterrupted power supply) for the wind turbine. Hereby you can use the electricity directly from the wind turbine while it is being produced. The UPS is used for starting up the wind turbines after a period without any wind.
Wind turbines are hereby very valuable in sparsely populated areas and/or remote areas without electricity supply. This could e.g. be isolated settlements or refugee camps as this solution permits lighting, heating, communication with the outside world, and a lot of other necessities, which are essential to a community in the 21st century.


The prototype of a printed circuit board or prototype of a PCB is a board used to connect electronic components to ensure the proper functioning of PCBs before production in larger quantities. The PCB prototype uses definite traces or electronic signals derived from copper components, which are laminated on incombustible material.
When the PCB prototype is completed, the electronic components are merged to form what is called prototype PCB assembly, and is usually done by soldering. Thereafter, testing is done in various ways to make sure everything works properly.
Prototypes of printed circuit boards have a conformational coating that is usually made of materials such as epoxy, polyurethane and the like. The coating is applied to prevent corrosion or leakage currents and short connections due to condensation.
Since PCBs have become one of the best-used technologies, it is essential to realize a significant cost advantage. Many companies offer the option of cheap PCB prototypes, many of them claim to offer the best deals on the market that offer customers a distinct advantage.
Different stages, including design and production schedules. Usually, the only details that are required are Fab Drawings or Gerber Files except for any additional requirements such as number of layers, type of material used, soldering mask, mask color, silk screen, screen color, plate thickness and the amount of copper needed at surface of the board.

Solar power has gained a lot of interest over the last few years and it has become increasingly popular among consumers due to its eco-friendliness and relative affordability.
Solar power is generated when solar photovoltaic panels, or solar panels as they are more commonly called, convert sunlight into electricity. Solar electricity can, in effect, be considered free electricity once the initial set up cost of installing solar panels has been cleared.
With solar panels, the yearly electricity production graph usually resembles a bell curve. The low end of the curve represents the winter months and the peak is reached in the summer.
Indeed, solar power generation can often be so high that a household generates excess power. Although the excess is exported to the grid for others to use, it is still recommended the household try to take full advantage of the surplus power.
A special solar panel heats fluid using solar radiation, which is then transferred to a solar tank. The solar tank is a special geyser designed specifically for this purpose and is much more robust that a normal electric geyser. The solar geyser has a back-up electric element so that on days with no sun, you will still have hot water.
Electricity is generated by silicone cells in solar panels. The electricity created is direct current (DC), while we use alternating current (AC) in our homes. An inverter is used to convert the electricity into AC. There are different types of systems available, depending on how much you are willing to spend and what your priorities are.
Whether you make your own or purchase a pre-assembled unit, solar ovens are increasingly popular home appliances. Like an electric-powered crockpot, a solar oven is essentially a slow cooker. Using angled reflectors that direct solar energy into a special chamber, a solar oven heats food to relatively low temperatures over the course of many hours.
Outdoor Solar Lights
Outdoor solar lights (such as solar security lights or solar flood lights) use solar cells to convert sunlight into electricity. Outdoor solar lights store this electricity in special batteries. At night, these batteries power the lights.
Both self-contained units, such as solar security lights and flood lights, and separate solar cell panel units need to be placed in sunny locations. Before purchasing a solar lighting system, check to be sure that the manufacturer provides replacement batteries and bulbs. Also, consider your home’s landscaping.
Solar Powered Ventilation Fans
Ventilation fans of any type are a good idea since they help reduce cooling costs by exhausting hot air from attic spaces and other areas. Traditionally, these exhaust fans are wired into household electrical current, which somewhat defeats the energy-saving purpose. Now, however, you can buy self-contained roof vent fans that feature a small panel of photo-electric cells that operate the fan motor with no need for household electrical current at all.
Solar Powered Pumps
For maximum energy-saving impact, you can also run those circulating pumps on solar power through the use of photo-electric panels, which will generate the power to run DC motors on the circulating pumps. While there is, of course, some investment in getting such a system set up, you have now reduced the operating costs of your hot water system to almost nothing.
Like any photo-electric system, the sun’s energy can be stored in batteries so that you can still run the circulating pumps at night or on cloudy days.

The TMF platform supports 2 hardware types for opening a garage door. When the user has an active reservation for a vehicle that is parked behind a garage door, the user will be shown a button in the app to open the door. Pressing this button will send an open command to the garage door. The garage door should close automatically again after a certain time.
Access to the garage door
The TMF server only allows the opening of a garage door for users with an active reservation, or a next reservation, for a vehicle service unit where the home zone has an associated garage door specific for that vehicle service unit. Do note that currently in the app ,the open button is only shown when the user has an active reservation.
This section will be added once garage doors are integrated in control center. TMF support will do the configuration for you until Garage doors are implemented in the Control Center.
WeSmartPark is a garage door opening system that supports sending opening commands via bluetooth and over the internet. Currently TMF only supports sending opening commands over the internet. This means both the hardware and the end-users' phone should have a stable internet connection. Supporting bluetooth for WeSmartPark garage doors is planned.

When it comes to listening to music, some of us prefer the bigger type of headphones and other may prefer the smaller earbuds. Whatever would be your preference is, whether you like the bulky headphones that cover your ears and with headbands more, or prefer the not so noticeable earbuds that can be inserted in your ears, there is only one thing that we always pay attention to.
We want our audio devices to deliver great sound quality. But before we take a look at what are the best Bluetooth wireless earbuds in 2020, let us first discuss what should you be considering in picking your wireless earbuds.
1) Similar with bigger types of headphones, you want your wireless earbuds to deliver the same sound quality as with the bigger headphones. Not just because they are smaller, they should be weaker. Since the technology used is the same, you should experience the same clear, crisp, and solid sound.
2) When it comes to audio devices, the cheaper ones tend to not deliver good and stable audio quality based from my experience. Although some are good in the first weeks of use, but since they are made with cheap materials, the quality deteriorates easily. It is recommended that you invest in audio devices whether it is an earbuds or a wireless home speaker.
3) In this era of technological breakthroughs, you should not just settle for good sound or durable audio device. It is better if your wireless earbuds has at least the must-have basic features such as long battery life. Wouldn’t it be even better if it has a noise-canceling or waterproof or sweat-proof features too? How about fast charging or auto ON/OFF features? Of course as much as possible we want those functions.
4) What is also very important when it comes to wireless earbuds is comfort. You cannot enjoy your music if your ears hurts after a considerable period of use. I like earbuds that matches the shape of your ear, not big or not small, but just fit enough so as not to cause discomfort,
Without further ado, the following is the list of wireless earbuds that are worth considering for if you want to have one.

Maximizing battery life
Lithium Ion batteries cannot be serviced, replacing them is an expensive and difficult task. Therefore it is important to maximize the life the installed battery pack.
Watch this video to learn about batteries:
Heat is the enemy of lithium ion batteries. Heat is generated from rapid charging, discharging and aggressive driving. These conditions reduce the useful life of the battery.
Figure 24: Battery life is affected by temperature (Professor Chang at Fully Charged, Dublin 2012)
It's difficult to state the lifetime of batteries with absolute certainty. However if the batteries are cooled sufficiently and kept mainly between 20 - 80% charge they should be able to outlast the vehicle.
Modern EV's typically come with a 5 year battery warranty, leasing schemes are also available.


Context and challenges

The solution, which helps the diagnosis and patient management of Covid-19 patients with Artificial Intelligence Technology, has started to be implemented in Medistate Hospital for the first time in Turkey, together with several centers around the world.
In this way, in the lung tomography examination, which plays an important role in the evaluation and management of Covid-19 patients, it is aimed to better detect Covid-19 patients with the help of artificial intelligence and to make efficient management in the process from hospitalization to intensive care or discharge.
Our hospital Radiology Clinic Director, who contributed to the development of artificial intelligence software, Assoc. Dr. Kaan Meriç states that “With Lung Tomography examination, Covid-19 patients at the initial stage can detect the disease in cases where the test results cannot be obtained or even if they have false negatives.”
What is the Purpose of Artificial Intelligence?
The overall goal of the first phase was to develop algorithms that have the potential to help physicians perform patient triage (classification) with a faster and more accurate diagnoses.
Artificial intelligence software increases the accuracy of the diagnosis when evaluated together with the clinical and examination findings of the patients in the second stage.
While currently used PCR tests (cotton swabs) give a result about whether the patient is infected at the earliest 4-6 hours (in some cases, days later), the damage to the lungs due to Covid-19 can be seen immediately in the Computed Tomography examination of the patient’s lungs. The artificial intelligence program allows more accurate identification of the affected lung tissue in the CT scan and can be used to score the severity of the patient’s condition.
Benefits for hospitals, doctors, and patients:
It provides better triage (discrimination) in the severity of the infection in Computed Tomography examination.
The AI program helps busy healthcare professionals screen patients and prioritize the most likely patients.
It allows more accurate assessment of ICU beds for the most severely infected patients.
We are also working on the development of the follow-up module in order to follow up the artificial intelligence software of the first installation of the clinical application in Medistate Kavacık Hospital in Turkey, in order to follow up the patients’ lungs due to Covid-19 in the advancing processes, and if there is any.
