One of our projects includes extracting stock market data of different tickers and visualizing them to find trends. Visualization parameters were stock price, market cap, gross profit, and revenue, etc. on different time periods of daily, monthly, quarterly, and yearly. Python was used as the language to pre-process and visualize the data
On basis of changes over specific periods of time, companies were shortlisted and a qualitative analysis on those companies was carried out to see why the stock prices drops or rise i.e. in case of McDonald’s, stock price a highly related with opening and closing of new branches.
This project includes converting voice to text using google API in real-time and applying analytics on the text i.e. words per minute, frequency of top 20 words and repetition of words, etc. A simple web page was designed to visualize the output of python based voice analytics.
This was a research project in which the task was to classify COVID-19, normal, and pneumonia class. Pre-trained CNN models like ResNet-50, NasNetLarge, and VGG-16 were used for classification after fine-tuning. For localization of the affected area, a technique called grad-cam was used. Python was used as the language used for coding.
This was a research project to highlight the previous work done in the health monitoring domain. A literature review was done in the following domains:
This project investigates one application to the analysis of image data for speciï¬Âc nonuniform spatial features. Spatial cross-correlation, spectral cross-correlation and convolution are investigated as possible image processing techniques. Further real-world spatial distances are determined from images from depth maps. These techniques are combined with applying statistical. Find statistical information about moth-eye SEM images. The defect quality and other properties are determined using computer vision algorithms and feature extraction. The ï¬Ânal program gives an output of statistics for the moth-eye SEM image. These three experiments were conducted:
Electrical grid stability has become a major issue with the uprise of renewable energy sources as it is difficult to keep the steady flow in the bi-directional systems. To check the stability of the grid some parameters are suggested on which datasets are formed. One of the Dataset is "Electrical Grid Stability Simulated Data Set" by UCI. It contains different parameters on which the stability of the Grid is determined. On basis of these parameters, features have been identified that have the same data across 90% of the rows. Different Machine Learning approaches i.e. Neural Networks, Random Forest, SVM (State vector Machine), KNN ( KNearest Neighbours ), Decision Trees, etc. have been implemented and compared in this paper and the best model has been chosen to check the stability of the grid.
This was a market project in which we have the data of customers related to a specific business. This was a uni-class classification problem where we grouped our customers who have already bought the services and applying the classifying model to customers who have not bought the services yet. In the end, we got the list of customers who are more likely to buy a specific service from all the customers who have not bought the service yet. Python was used to implement data pre-processing and applying machine learning algorithms.
This was a research project in which a review of biometric recognition systems was done. Biometric recognition has been a very important way of surveillance for a very long time now. There has been a very vast work present in the field of both multi-model and uni-model recognition systems using deep learning along with preprocessing done through Generative Adversarial Networks (GANs). we looked at the latest trends and work present until now. We discussed all the strategies and datasets that are used mostly along with accuracies achieved by those strategies. The project aims to give an overview of the field of biometric recognition through deep learning.
COVID-19 has spread at a very fast rate and it is important to build a system that can detect it in order to help overwhelmed health care system. The strength of deep learning techniques is used in many research studies of chest-related diseases. Although some of these researchers used state-of-the-art techniques and was able to provide promising results, these methods do not provide much benefit if it can only identify one type of disease without identifying the rest. In order to deal with this problem, a novel pipeline was introduced for the detection of COVID-19 along with other chest diseases from X-ray images. This pipeline reduces the burden of classifying a large number of classes on a single network. Lungs and heart are segmented from the whole X-ray image and passed onto the first classifier that checks if the X-ray is normal, COVID-19 affected or belongs to other chest X-ray disease. If the case is neither COVID-19 nor normal then the second classifier comes into action and classifies the image as one of the other 14 diseases. With our new pipeline, we show how our model makes use of the CNN state-of-the-art deep neural networks to achieve COVID-19 classification accuracy with 14 other chest diseases and normal X-ray images that is competitive with present state-of-the-art models.

Unmanned Underwater Vehicle (UUV) drives underwater without requiring any real-time input from a human operator. These robotic vehicles are mostly used to explore the underwater world. These vehicles can be designed to perform underwater specific tasks like the exploration of the underwater world and spying etc. The readily available UUV’s present in the market is of high cost ranging from 2000$ to 3000$. To reduce the production cost of a UUV, many pieces of research are in process worldwide. A lot of physics concepts have to be used while designing such vehicles. Image Processing is an essential feature of UUV based on which it performs underwater tasks. There are many constraints in performing underwater image processing as the turbidity of the water changes when one goes deep in the water. It mostly suffers scattering, limited range, low contrast, and most importantly blur in the images that create problems for UUV to perform its tasks efficiently. We propose a basic software, electrical, and mechanical hardware design for UUV. PVC pipes were used for designing the structure of UUV, Raspberry pi acts as the processor of the UUV, and bilge pumps act as propellers. Our design is much simpler than the readily available UUV’s in the market. It is a low-cost UUV that performs specific tasks like goal post-detection, color detection, and obstacle detection based on template matching. It is developed for under 300$. One can add more features to a UUV to perform underwater photography and observation of marine life. The efficiency of the UUV system and battery life is enhanced for better functionality. A special waterproof container is being developed and attached to the UUV structure for waterproofing of the whole circuitry.
Unmanned Underwater Vehicles (UUV) operated underwater without any human interference. UUVs can be used for many purposes i.e. exploration or spying. They have several designs and each one can be used for a specific purpose. The main problem that limits the functionality of UUV is poor image quality. The reason behind this poor image quality is scattering and wavelength absorption. The purpose of this research was to propose an electrical assembly design of low-cost UUV. In order to carry out this work use of Raspberry Pi is proposed which is a small computer on its own. It can be used to enhance image quality and detect objects along with color detection. For controlling the propellers in accordance with any hindrance, pulse width modulation (PWM) GPIO pins are used. GPIO pins are also used to attach sensors. For enhancement of images python 3 was used and different image enhancement methods were tested on basis of execution time per frame. In the end best model is selected which is more suitable on basis of execution time and image enhancement. In order to transmit the images from UUV to the base computer wi-fi module of Raspberry pi is used.


In keeping with my guitar circuit project, I wanted to delve into what the tone circuit actually does. The results were very surprising to me. I discovered several things about the tone circuit and its implications to the design of my new active circuit.
Voltage Divider and Resistor/Impedance Combination
Let me make sure we're all on the same page with voltage dividers. This is a very basic idea for anyone familiar with electronics, but for those who aren't, it isn't very complicated. Recall the idea of voltage drop, that voltage across a resistor is distributed along its length evenly. If you tap the resistor at a specific point (which is what a pot does), then you will get the voltage at that point. What you're actually doing is dividing the resistor into two resistors in series, which is also known as a voltage divider.
This is your standard voltage divider.
The two resistors can be two halves of a pot, two separate resistors, or theoretical equivalents to several resistors combined according to the following techniques.
Series resistors are connected such that one lead on R1 is connected to one lead on R2 with no other components in between. (such as those in the voltage divider above)
Parallel resistors are connected such that each lead of R1 is connected to exactly 1 lead of R2 with no other components in between. (Take out the voltage source in the voltage divider, and the resistors are in parallel.
Finally, recall that impedance is resistance generalized over all frequencies. Capacitors and inductors have frequency dependant impedance. Resistors have frequency independant impedance with is equal to their resistance (ideally). Impedances combine exactly like resistances (series and parallel, that is)
Here I will simplify the pickup model to just an ideal voltage source and a series resistance (R int). The tone circuit is next in line and is parallel to the volume circuit.
As you can see, only two terminals of the tone pot are connected to the circuit. The third does nothing. This makes the pot a simple variable resistor. I will show the effect of the resistor later.
I have said that the capacitor impedance varies with frequency. The capacitor in my guitar is a 0.22uF. This is the plot of the magnitude of its impedance vs frequency. Strictly speaking, impedance has an imaginary component, so I am always graphing magnitude. But I will just use the term impedance to mean "magnitude of impedance."
The tone circuit requires pickup resistance
One thing that I didn't realize until doing this analysis is that the tone circuit depends heavily on the resistance of the pickup itself. The half power frequency or cutoff frequency of the RC filter is
If you replace the pickup with an opamp, as I have done in the Active Circuit described in a previous post, then R=0, and your filter won't work. The cutoff frequency will be infinity. Ideally, the whole tone circuit will have no effect on the signal at all!
The Response of the Circuit
I pulled out trusty old Matlab and made a simulation of this circuit. My measured values on my guitar were as follows.
Rint = 10.87 KOhms
Ctone = 0.22 uF
Rtone = 0 Ohms - 500 KOhms
Rvol = 0 Ohms - 500 KOhms
The x axis is frequency from 20Hz to 20KHz (the entire audible range). The y axis is gain. A gain of 0 indicates no effect on the circuit. A gain less than zero indicates some attenuation to the volume at that frequency. The different lines represent different settings on the tone pot (i.e. different values of Rtone).
For those familiar with the Bode plot of an RC Filter, the bottom line should look familiar. It rolls off at 20dB per decade from the cutoff frequency of about 66Hz. (Maybe this is why my tone sounds terrible when turned all the way down). As we increase the value of Rtone, the frequency response flattens out until there is no attenuation at all to speak of.
If we were to remove the capacitor all together, then the filter would be a simple voltage divider. So when the capacitor's impedance becomes negligable compared to the impedance of Rtone, then the gain flattens out to approximately what a voltage divider would be. As Rtone increases, the range of effectiveness of Ctone becomes smaller and smaller until it doesn't really affect the signal at all.
Log vs. Linear Tone Pot
I've heard some debate about log vs linear pots on tone circuits. Let me show you the difference. The original plot above is for a log pot. The steps on Rtone are spaced logarithically from 0 to 500K. The next plot is for a linear spacing between 0 and 500K.
Notice that the available responses are all grouped towards the top. There are very few response curves that are not practically flat. There are 50 steps between 0 and 500K in the simulation. Notice the vast difference between 0 ohms and the first step (10K or 1/50th setting on the pot). You will be pretty much unable to get any responses between those two, unless you have very very steady hands.
So I believe this is pretty strong evidence that maximum control over the tone can be had using a logarithmic pot instead of a linear pot.
The Meaty Part: Analyzing the Effect of Rtone
Here's where things get a little more difficult to explain intuitively. I worked and worked to get an analytical solution to this circuit. I probably should not admit that, because it's a very simple circuit. But part of my problem was that I was convinced that my answer was wrong when it was not. Let me explain. The equation for the gain of the circuit is
Obviously, this is a not very intuitive. But how about an equation for the cutoff frequency?
Ok, this is a little bit better, but still not great. I can see that the equation is very similar to the original, except that R is replaced by an uninviting square root. Wait! Notice that under the right circumstances, the quantity under the square root is actually negative. If you're reading this blog, then you probably know that negative square roots will not produce real numbers.
This was the point at which I kept checking and rechecking my work. But then I realized, that this is exactly what we observe in the response plot above. After a certain setting on the tone pot, the response never dips below -3 dB. Just what is this setting? If we set the quantity under the square root greater than 0, then we get...
To verify this result, I altered the simulation to graph only from 0-30KOhms. Here is the graph.
Answer: Pretty dismal. Yes there is a big peak at about 17KOhms, but if you look at the x axis, the majority occurrs between 15Kohms and 17Kohms. Other than that, the response is pretty flat. So we're taking about most of the change in frequency is between 3% and 3.4% of the pot. Not very practical.
By the way, the reason for the descrepancy between 17KOhms as the cutoff and 26KOhms is because I neglected Rvol in my analytical solution.
Apparently, adjusting Rtone is a crappy way to move the cutoff frequency.
Load Presented to the Pickup
I also checked the load impedance to the pickup. As I've shown in a previous post, the values of the pots greatly affect the signal strength and frequency output of the pickups. So it is of interest to us how adjusting the tone pot will affect the load on the pickups. Here is the chart.
If you do the math, the parallel combination of the two pots is 250K. Looking at the plot, the larger Rtone becomes, the more closely the load approaches 250K. The impedance of the capacitor was shown early in this post. So basically, low tone pot settings will cause a double whammy effect on cutting the highs. Since I didn't model the pickup with any inductance, this is not shown in the simulation, but you can combine the earlier article on pot resistances with this one to see that the effect will be heightened. Both the low impedance load and the low pass filter will tend to cut the highs out of the signal.
That was a lot of information about the tone circuit in a guitar. Here's the source code for my simulation...
% tone control simulation % 0.022 uF capacitor Ctone = 0.22e-6; % 500 Kohms Tone Pot Rtone = 500e3; % 500 Kohms Volume Pot Rvol = 500e3; % pickup resistance 10.87 Kohms Rpickup = 10.87e3; %actual guitar value %Rpickup = 10; %opamp output impedance worst case %Rpickup = 100e3; %for more cutoff frequency change % steps on the tone resistor %toneres = logspace(0, log10(Rtone)); %toneres = linspace(0, Rtone, 50); %toneres = logspace(1,log10(30e3)); toneres = linspace(0,30e3,50); % steps in frequency %freq = [ 20:10:20000]; freq = logspace(log10(20), log10(20e3), 100); ZCtone = repmat( (-j./(2*pi*Ctone.*freq)) , size(toneres,2),1); Ztone = repmat(toneres',1,size(ZCtone,2)) + ZCtone; Zeq = Ztone .* (Rvol*ones(size(Ztone))) ./ (Ztone + Rvol*ones(size(Ztone))); gain = abs(Zeq ./ ( Zeq + Rpickup*ones(size(Zeq))))'; fc = 1./(2*pi*Ctone*sqrt(Rpickup^2*ones(size(toneres)) + Rpickup*toneres - toneres.^2)); % look at the capacitor impedance figure(1); semilogx(freq,abs(ZCtone)/1000); xlabel('Frequency (Hz)'); ylabel('Magnitude of Capactior Impedance (KOhms)'); % total magnitude of load presented to pickup figure(2); semilogx(freq,abs(Zeq)/1000); xlabel('Frequency (Hz)'); ylabel('Magnitude of Load Impedance (kOhms)'); % plot gain of circuit figure(3); semilogx(freq,20*log10(gain)); xlabel('Frequency (Hz)'); ylabel('Gain (dB)'); % plot fc of circuit figure(4); plot(toneres/1000,real(fc)); xlabel('Rtone (KOhms)'); ylabel('Cutoff Frequency (Hz)'); I hope that this has been enlightening to you. It certainly was for me. Basically tone control circuits are pretty crappy. I have done some research into better circuits, especially active ones. You can directly adjust the cutoff frequency using Sallen-Key filters by adjusting the two resistors and keeping the capacitors constant. This is a good thing, since variable capacitors are not very practical for guitar circuits. I will post more on this topic when I have come to some more conclusions. As always, thanks for reading.

Life-Changing 3D-Printed Ear Prosthetics from FutureHear and NinjaTek
Application: Ear prosthetics for children
Material used: NinjaFlex® 3D Printer Filament
FutureHear’s goal is to change people’s lives by providing personalized prosthetics. Thanks to 3D printing technology and NinjaFlex 3D filament, this project out of Brisbane, Queensland, Australia, is creating low-cost ear prosthetics for children. Babies born with microtia, a condition where the ear has either not formed at all or is only partially formed, affects 1 in 6,000 kids.
“3D printing allows us to make things personalized,” said Mia Woodruff, an associate professor at Queensland University of Technology. “It’s a technology that everyone’s adopting, and the LulzBot 3D printers are just so reliable and low-cost compared to other manufacturing techniques.”
In phase one, photogrammetry is used to scan the child’s ear with a smartphone, making a three-dimensional file. A reverse mold is then created and printed using a LulzBot 3D printer. Finally, medical-grade silicone is injected into the mold to create an anatomically precise ear matching the other side of the child’s head.
The second phase of the FutureHear project will focus on making tissue-engineered, permanently implanted ears. The third phase will look at creating bionics with functional hearing components that are integrated into the ears.
“FutureHear is about future hearing, and it’s about the future lives of these children to make them have exactly the same opportunities that all the other children have,” Woodruff said.
“In addition to the molds, LulzBot 3D printers are using NinjaFlex to make the internal cartilage structure for FutureHear.”
Regardless of the application, using LulzBot 3D printers in FutureHear projects has had many benefits.
“We were looking out for really, really reliable printers that looked good, that had a good reputation, didn’t break, and that were Open Source [Hardware],” said Woodruff. “The Open Source [Hardware] is the huge plus factor here with the LulzBot 3D printers, so we love how accessible the company is.”
The fact that LulzBot 3D printers are robust and can withstand movement and use is an additional advantage.
“We take them to a lot of showcase events,” Woodruff said. “We’ve taken them to at least five, and they’ve never malfunctioned, they’re easy to level, and the cost is so incredibly competitive. They are the reasons we stick with it, and we just have such nice interactions with the company.”
In order to try to see the work with FutureHear into the new year, a crowdfunding campaign was launched.
As FutureHear works to change the lives of these children, 3D printing remains a vital tool.
“3D printers are amazing,” Woodruff said. “They’re revolutionizing the world; to see how it can be used to have an impact on someone’s health and well-being is quite incredible.”

Getting started with ESP8266 and MicroPython
I like the idea of Internet of Things (IoT) which is becoming so popular. We have everything connected to the Internet: TVs, printers, fridges, cars, even teeth brushes, etc. We already have botnets which consist of IoT devices, and are used for massive DDoS attacks. I personally prefer calling it “Internet of Shit” because sometimes it’s not clear why some devices connect to the Internet. By the way, there is a twitter called “Internet of Shit”. I highly recommend to follow.

Blockchain Business Process as a Cyber Strategy, a Tool for Defensive Social Engineering
April 12 @ 9:45 am - 10:45 am
Blockchain has become a buzzword that everyone has heard about and few fully understand. Technology and innovation teams across every sector are scrambling to develop new use cases for blockchain and pilot technology in this regard. Generally, the pilots developed are not scalable due to cost requirements or business need and the resulting projects are sent to the pilot graveyard – the flashy, client-facing testbed. Despite the many challenges associated with developing blockchain products and services, there is substantial opportunity to use blockchain as a cyber security strategy. In the talk, we will discuss the fundamental enablers of the blockchain and how it can be used as a business process. While the technology behind blockchain is interesting, the methods behind the blockchain can be scaled and generally applicable across industry as a means for defensive social engineering. Defensive social engineering is a toolbox of social and business process strategies we developed to defend against cyberattacks. Blockchain as a process is one strategy in our toolbox. This session will help you understand how blockchain can be used to drive scalable and secure business processes in your organization.

Many people think of data rooms when they think of due diligence, which is the process that aids in the financial and legal negotiation of a deal between two or more parties. However, the advancement in technology of these platforms has meant that they are now also becoming increasingly used for a full range of business transactions such as fundraising, divestitures and even restructuring.
The best virtual data rooms provide a wide range of security and document management options that can be used for all kinds of transactions. Auto indexing and bulk uploads are typical features that allow you to build a robust file system quickly. They also come with the ability to search that integrates several criteria to provide quick and precise results. Some also have a fence‘ feature that blocks out parts of a document to stop unauthorized screenshots or downloads. Most reliable providers offer access security features such as multi-factor authentication, granular permissions for users as well as IP and time restrictions.
Certain vendors provide integration with artificial intelligence or machine learning (AI) tools that could assist during due diligence by reducing the amount of documents to be reviewed. This is particularly beneficial when dealing with lengthy or complex documents.
Other essential technologies that are available in the most trusted rooms include a drag-and-drop interface, multilingual support, OCR, file preview, and smart AI categorization. These capabilities make it simpler to navigate and search huge quantities of data, especially when they are available in multiple languages.


Most monitors sold today use a Twisted Nematic (TN) LCD panel. The advantage of this LCD technology is that it is cheap to produce and that TN panels can change state quickly, giving them the best response time of all available LCD technologies. This makes the panels more appropriate for games that render fast image transitions. Thanks to the combination of low cost and rapid response time, TN displays are by far the most popular today.
How Does a TN LCD Work?
The discovery of the TN effect was a revolution in flat screen technology and for all intents and purposes is it what brought LCD technology into the mainstream. The effect means that the liquid crystals are controlled and restructured into different molecular configurations under the influence of an electrical field. It requires that the liquid crystals can be turned between “on” and “off” states. This is achieved by letting the current pass through layers of film (hence the name Thin Film Transistor, or TFT). Twisting it 90 degrees lets no light through, whereas another state lets though the specific sub-pixel colors red, green or blue (RGB). If the red, green and blue sub-pixels are all fully lit, the pixel turns white.
The virtues of the Twisted Nematic technology include the lowest response times among modern flat screen displays, as well as a low production cost. The downsides–at least in early generations–are poor color rendition and narrow viewing angles.
The different layers of an LCD monitor can be seen on the right: The first is a vertical film that polarizes the incoming light, the second layer is a substrate with electrodes, the shapes of which will determine what shapes that appear on the screen. Layer number three is the one that is made up of Twisted Nematic crystals that control the flow of molecules. The fourth is another glass substrate; unlike the first, which is the vertical polarizing filter, this layer acts as the horizontal filter. The final layer is the surface that absorbs and retransmits the light source, whether it comes from more modern and power-efficient LEDs or compact fluorescents (image credit: Wikimedia Commons).
TN Panel Pros and Cons
As previously mentioned, viewing angles and color reproduction are not areas where TN panels excel compared to other, more expensive displays. Seen from a steep angle, the image discolors quickly; viewed from below the picture can be very dark and looking at it too far from the top, the contrast can reverse itself, allowing light to dark shades and vice versa.
Although TN panels and monitors with this technology has great strides in recent years, the color accuracy is not on par with monitors using In Plane Switching (IPS) and Patterned Vertical Alignment (PVA) panels. On the other hand there are some significant drawbacks with these panels too.
First of all, they are more expensive than TN, and IPS, PVA and other high-end alternatives are less suitable for gamers, as they tend to have higher (=worse) response times. However, for color critical applications such as photography, video editing or web design, monitors with IPS and PVA are still the best choice.
Other weaknesses of TN is the moderate levels of contrast and the ability to produce blacks and whites accurately. However, today’s monitors are considerably better in this respect than they were just a few years ago.

RS232 to TTL level converter
When developing a product that communicates over RS-232 it happens frequently that the product uses TTL levels. The serial (COM) port of a PC uses RS232 levels, so a level converter is required. This RS232 to TTL level converter solves this problem in a convenient way.
The level converter is a standard component, but needs some circuitry to be useable. We use the ICL3221 in a TSOP package.
On the PCB 3 LED's are mounted to indicate power supply, Rx and Tx. This level converter is suited for 3-wire communication only: Rx, Tx and ground. The device needs an external DC 3.0 to 5.0 V power supply.
RS232 to TTL stamp assembly
The circuit is as small as a real stamp and it will fit in most (long type) D-sub hoods. This hood can be ordered separately from us or from Farnell.
You can download more information about the RS-232 to TTL level converter below:
Datasheet of the ICL3221 (865 KB)
Schematic and component layout of the RS-232 to TTL level converter(165 KB)

I bought some extra RAM for my machine (it has 4GB of RAM now). However, the computer would not recognize the extra RAM. So, off I went to my motherboard manufacturer’s site and looked up possible BIOS updates.
And then, the question is…how do you update your bios without a floppy disk. I did not have cd-rw’s at hand, so I had to get it working with a usb flash drive.
After lot of research, I found a

GSK boosted to 90% electronical invoice processing
How GSK grew e-invoice processing volumes with Tungsten Network.
GlaxoSmithKline plc (GSK) is one of the world’s largest pharmaceutical, biological, and healthcare companies.
In 2014, GSK was processing ~60% of its invoices electronically via Tungsten Network. Following a huge internal effort, working in concert with Tungsten, GSK was able to drive up processing volumes while driving down the cost, benefitting from Tungsten’s global coverage and ability to deliver invoices that comply with international tax regulations.
“We recognised that electronic invoicing could be a complementary way of increasing levels of automation. Many of our suppliers were already on the Tungsten Network platform, which helped us validate the technical solution.” – Jens Fischer, Global Process Manager, GlaxoSmithKline


When looking into moving away from a traditional phone system whether you are looking for more features or are forced to because phone system is no longer supported. You will see VoIP, PBX, SIP, and SIP Trunk all thrown around, but what do these actually mean, and what do they provide for you.
Let’s start with PBX or (Private Branch eXchange) this over time has become a generalized term to mean a business telephone system that handles the routing and switching of call between a business location and the PSTN (Public Switched Telephone Network). Which received its name from the phone system beginnings when it was a switchboard operator who would route and connect the calls with the telephone network. You can think of a PBX like a tree you have the (trunk) the main line connecting to the telephone network, then (Branch) the smaller endpoints that connect to it and handle smaller amounts of traffic, then finally the (Leaves) Destination Endpoints such as phones, fax, machines, etc. that receive and originate the traffic. “Private” is the fact that though it can connect to the PSTN it is also separate from it. “Branch” describes the properties of how a PBX fits into a PSTN, and “eXchange” the method by which connections are exchanged through a switching system, by which allowing a larger number of calls to be routed through a limited number of lines. Hosted PBX is simply the transition of moving from a hardware based on-premises system to a virtualized cloud system, thus allowing for greater expandability, redundancy, and reach.
Next is VoIP (Voice over IP) also called IP Telephony, is the group of methods and technologies that allow the delivery of voice communications and multimedia sessions over IP (Internet Protocol) networks such as the public internet. This VoIP technology converts the analog voice signal used in traditional phone calls into a digital signal that is broken up into packets that travel via the Internet rather than analog phone lines. VoIP service also enables a larger variety of calls such as video, conference, webinars, and telephone for both commercial and personal use, at affordable prices. Previously web conferencing, and video conferencing were limited to companies that could justify the expense for dedicated links and specialized hardware. There are also a few cons to VoIP, such as internet outages, power outages, network congestion, and LAG. Also, to be noted is 911 services, make sure you have an e911 registration for all of your locations, because typically non-identified 911 calls to the centralized call center can be charged up to $100 per occurance!
Next is SIP (Session Initiation Protocol) it is simply one method of facilitating voice communications as well as text and video. Commercial and residential users that don’t need to interface to a traditional analog line, and simply want inbound and outbound calling do not need SIP, VoIP alone would be enough. However, for example if your business has an on-premises PBX or phone system, you can transition to VoIP by having a SIP Trunk connecting your system to the internet, removing some of the costs of copper, PRI, T1 or T3 connectivity to the PSTN Network.
For the most part with a quality UCaaS provider such as The Phone NutZ supporting your Hosted PBX, trunking is built into the system. And if you are in transition or fully migrating, we can connect you with SIP Trunking, local phone numbers, long-distance phone numbers, or keep your existing number and have us port it to your new Hosted PBX or SIP Trunk.

Home automation can include the scheduling and automatic operation of water sprinkling, heating and air conditioning, window coverings, security systems, lighting, and food preparation appliances. Home automation may also allow vital home functions to be controlled remotely from anywhere in the world using a computer connected to the Internet. Besides the functions already mentioned, remote control can be extended to telephones and answering machines, fax machines, amateur radios and other communications equipment, and home robot s such as automatic vacuum cleaners.
The fundamental components of a well-designed home automation system include a computer (or computers) with the appropriate programming, the various devices and systems to be controlled, interconnecting cables or wireless links, a high-speed Internet connection, and an emergency backup power source for the computer, its peripherals, and the essential home systems.
THE INTERNET OF THINGS: (IoT) Simply put, this is the concept of basically connecting any device with an on and off switch to the Internet (and/or to each other). This includes everything from cellphones, coffee makers, washing machines, headphones, lamps, wearable devices and almost anything else you can think of.
On a broader scale, the IoT can be applied to things like transportation networks: "smart cities" which can help us reduce waste and improve efficiency for things such as energy use; this helping us understand and improve how we work and live. Take a look at the visual below to see what something like that can look like.
The reality is that the IoT allows for virtually endless opportunities and connections to take place, many of which we can't even think of or fully understand the impact of today. It's not hard to see how and why the IoT is such a hot topic today; it certainly opens the door to a lot of opportunities but also to many challenges. Security is a big issue that is oftentimes brought up. With billions of devices being connected together, what can people do to make sure that their information stays secure? Will someone be able to hack into your toaster and thereby get access to your entire network? The IoT also opens up companies all over the world to more security threats. Then we have the issue of privacy and data sharing. This is a hot-button topic even today, so one can only imagine how the conversation and concerns will escalate when we are talking about many billions of devices being connected in the years to come.

Wearable devices and tattoos are so last year. What we’ve laid our keen eyes on is the wearable tattoo.
Now, in what universe would we need wearable tattoos? Let’s have a look.
Wearable Tattoo #1: Health Tracking
Researchers have created a wearable electronic that “looks and feels like a henna tattoo but can monitor electrical muscle activity and body temperature“ Download Kirai. Made of breathable material called nanomesh, this can be worn without causing any skin irritation. It’s easily applied like a kid’s temporary tattoo. While participants successfully wore these on their arms for 7 days without any adverse skin reactions, the drawback is that these tattoos get washed off with water 파이썬 64비트. So…did they not shower for an entire week?
Still a work-in-progress, guys. For more reading pleasure, check out the paper that was published in July 2017 here.
A little further back in 2016, MIT and Microsoft Research created a “smart tattoo” called DuoSkin that can “turn into a touchpad, remotely control your smartphone, or share data using NFC“ 컴시간 알리미.
MIT has developed temporary tattoos that can control your devices.
Posted by The Verge on 12hb Ogos 2016
While this is undoubtedly impressive, we only have one question: Why Download more than flowers?
Wearable Tattoo #2: Information Bank
Or, your banking information.
US tech design firm Chaotic Moon is experimenting with “conductive paint and electronic components, including LED lights, to build skin-mounted gadgets that could be used to monitor vital signs or hold credit card information.”
When fingerprint sensors on smartphones became a thing, we all wondered about how criminals would bypass that security measure Download ireland. So, we’re wondering the same thing – would we get skinned or de-limbed?
But on a serious note, getting your vitals checked without needing to go to the doctor sounds fab!
Wearable Tattoo #3: Power Generator
Now, this one we can get onboard.
First developed as a fitness tracker, this tattoo detects lactate, which is present in sweat. In general, the more intense the exercise, the more lactate the body produces. Professional athletes monitor their lactate levels during performance testing as a way to evaluate their fitness and training program 윈도우xp 서비스팩3. Currently, lactate testing is inconvenient and intrusive because blood samples must be collected from the person at different times during the exercise regime and then analysed.
In developing a faster, easier, and more comfortable way of measuring lactate, researchers from the University of California, San Diego found that the sensor begun generating a weak electrical current Download Microsoft Office for free. From there, they decided to work on a sweat-powered biobattery. The current produced isn’t very high, but the team is working on enhancing it to power some small electronic devices.
Also from the same institution, a team has also developed a wearable tattoo that can detect glucose levels in your body. A great step forward for patients with diabetes!
Wearable Tattoo #4: Skin-ducation
A familiar name, L’Oréal, first debuted the My UV Patch in 2016 and refreshed it in 2017 for families 자바 무료. Connected to the My UV Patch app available for iOS and Android, the tattoo tracks sun exposure for multiple people and lets you know when it’s time to reapply sun screen.
The wearable tattoo is available for consumers but based on the app reviews, it seems like there’s much to be improved.
Wearable Tattoo #5: Just Because
Are you so sick and tired of having to key in your pin number, have your fingerprint or face scanned to unlock your phone 클래시오브클랜 apk? Motorola has got you covered with their Digital Tattoo, enabling you to unlock your phone without touching the screen.
They have also filed a patent for a neck tattoo, which acts like a sort of microphone by transmitting sound straight from the source into your phone. Super useful when you need to talk on the phone in a crowded and noisy area. Because walking away just takes too much effort.
Our verdict? Moto-no-lah.

Sky Motion: more accurate weather forecasting?November 7, 2013
My son Jason lives approximately 15 minutes east of me. Some time ago, when we were talking on the phone, I said, “It’s hailing here.” A few minutes later, he said, “Now, it’s hailing here.” We decided that if we could set up observation stations starting at the Oregon Coast on the west, we could likely get very accurate short-term weather forecasts.
Sky Motion, just acquired by AccuWeather, uses that concept and makes it even more reliable on the hyper-local level. The Sky Motion app on my iPhone combines analyses of radar images with ground observations from users.
So far, I’ve found it to be incredibly reliable!

You have probably heard the fact before that there is no sound in space, because it is a virtual vacuum. Yes, but technically, no. There may not be the sounds that we could hear, but the sound of the sun exists as electromagnetic vibrations in its coronal loops.
This is the reason why NASA could record these vibrations by specially designed instruments and transfer them into sounds by speeding up its frequency. Now, a research design project called ‘thedotisblack’ presented some audiovisual artworks based on recordings taken from NASA, allowing us to see what the sound of sun ‘looks like’.
David Mrugala, a German architect, designer and educator currently living in Korea, established this long term project in 2014, which explores generative drawings using the programming language Processing. As the project states, it combines “natural science studies, sound analysis, digital visualization and coding”.
It has released a series of audiovisual artwork relevant to planets, stars and space, mainly using data from NASA, ESA and other space research institutes. He carefully analyses the audio files before processing them with coding. Each complicated geometric picture comes with a video to highlight the visual expression and aesthetic reflection.
So far, the project has gained around 200,000 likes and re-blogs online. On its page at Ello alone, the number of viewing has amounted to over 2 million times.

Our daily routine could be a simulation – at least according to Melvin Vopson, Physics academic at the University of Portsmouth in England. As reported by the British newspaper “Daily Mail”, Vopson puts forward several indicators pointing towards a simulated reality and is planning an experiment to test this theory.
Vopson argues that the physical laws governing our universe resemble computer codes, while the elementary particles that make up matter could resemble pixels. Another indication, according to Vopson, is the limits on the speed at which light and sound can travel, which could indicate the speed of a computer processor.
Key indication for the Physics academic: symmetry in everyday life
One of the most convincing indicators, however, is the symmetry observed in everyday life, from butterflies and flowers to snowflakes and starfish. Symmetry is ubiquitous because it demonstrates how machines reproduce the digitally constructed world, Vopson told the “Daily Mail”.
How the scientist plans to prove his theory
To prove his theory, the physicist plans to collide elementary particles and “antiparticles” in a device. If the particles emit a specific light frequency spectrum upon their collision and annihilation, this could indicate that the particles contain information that seeks to escape.
If the particles contain information, according to Vopson, this would suggest that our reality is likely a computer program and we are living in a simulation. “Hello, Matrix!”

Combination of store IoT and cloud-based visual merchandising will provide new real-time visibility and analytic power.
NEW YORK (PRWEB) JANUARY 14, 2019 – Mobile Technologies Inc. (MTI), a global leader in consumer electronics retail security and One Doorâ„¢ Inc., a leading provider of cloud-based visual merchandisingsoftware, today announced a partnership to integrate their offerings. By combining MTI’s real-time store sensing with One Door’s visual merchandising and space planning capabilities, the partnership will give consumer electronics retailers new, real-time, visibility into the state of merchandising in their stores.
As part of this agreement, MTI and One Door will combine data from MTI Connect, an open IoT retail platform that provides real-time store visibility, with data from One Door’s Our platform, a cloud-based application that delivers space planning and visual merchandising capabilities including in-store execution and compliance management.
For retailers looking to make more frequent changes to their stores and localize their product promotions, communicating and confirming merchandising initiatives is becoming more time-consuming and costlier. “The combination of our real-time store data and Our platform’s tailored and guided store plan will provide associates with up-to-the-second information on how they can take action to improve their merchandising results, and maximize sales,” says Matt Haroldson, VP of Global Marketing at MTI.
“Space planners and visual merchandisers using traditional planograms have limited confidence in the quality of merchandising in stores,” said Dan Wittner, COO of One Door. “We look forward to partnering with MTI to incorporate real-time store data into Our platform’s existing compliance measurement capabilities, further improving corporate visibility into the quality of merchandising.”


Smart textiles combine the qualities of textiles with intelligent and innovative technologies that open up new opportunities in safety, comfort, and smart products. This technology can also be integrated into textile belt straps to create “intelligent belt straps” for certain applications.
Smart textiles can:
- register and forward / transmit vital signs
- light up
- heat / cool
- react to temperature fluctuations
- display information about force, pressure, humidity …
- transmit a constant status report to security systems
- vibrate (discreet notification to a driver)
- house integrated switches (pressure, capacitive)
“Intelligent belt straps” can be used for a wide range of applications. To name some examples, they can offer protection against theft and vandalism, or even give off signals in the event of accidental damage. If the belt strap is severed, for example, an alarm is triggered.

Most exoplanets--planets around other stars--that we have discovered have only been detected by measuring the wobble they exert on their star or by detecting a dip in stellar brightness as they pass between Earth of their star. This image is one of a growing number of direct images of exoplanets.
While these three planets have been previously directly imaged by another telescope in 2008, this image is one of the first images released from a new instrument on the Subaru Telescope in Hawaii. This instrument, called a chronograph, blocks out the light of the host star, allowing astronomers to not only observe the orbiting planets, but also dissect their light to detect the elements that make up their atmospheres.
This new chronograph on the Subaru telescope, dubbed CHARIS, is one of several new chronographs now being used to observe exoplanets, yielding more and more insights about planets around distant stars. CHARIS is capable of detecting and analyzing gas giants larger than Jupiter around other stars (no chronographs can yet directly detect Earth-sized exoplanets) and will be open for full scientific use in February 2017.


The Chetak is perhaps one of the most iconic scooters in India. To honour its legacy, in 2019, Bajaj Auto announced that it will be revived with an all-new electric powertrain, simply called as the Bajaj Chetak electric.
After being announced earlier last year, the Chetak electric was unveiled in October where preliminary specifications and the design were showcased, along with features and global availability. The minutiae and the price were left undisclosed for a future event.
After months of wait, the Bajaj Chetak electric will finally launch in India on January 14. The first wave of sales will cover cities such as Pune and Bangalore, before making its way to other cities and then get exported to certain European markets, which is a rare feat for Indian electric two-wheeler makers.
The design is pretty reminiscent of the classic Chetak, but brings angular curves, smooth surfaces and new finishes which make it stand out. New horseshoe-shaped LED headlights with DRLs, touch-sensitive switches and a large digital console.
On the inside, the Bajaj Chetak electric scooter is powered by a 4kW motor and comes with two riding modes-Eco and Sport. An IP67 lithium-ion battery will run the show, with home-charging stations available to customers at an additional cost. The range is estimated to be about 95km on the Eco mode, and 85km on Sport.
Furthermore, the Chetak smartphone app will give a comprehensive overview of the vehicle, diagnostics as well as ride history. This will also bring improved security for users via user authentication.
The price will be announced at this upcoming event, but the Bajaj Chetak electric is expected to be available at upwards of Rs 1,00,000.

Superior Data Solutions has had a long track record of seeking the best solutions to the most difficult problems and bringing them to market. We have extensive experience in virtual desktop infrastructure, solid state disk technology, I/O performance and data virtualization.
SDS was founded in 2005 and brings innovative data center technology and solutions to market. SDS specifically focuses on technologies that recognize a universal problem and solve the root cause of the problem via innovative design.
In 2006 SDS was the exclusive distributor of the Gnutek’s Maracite SSD drive. The world’s first Enterprise class Flash SSD. Gnutek recognized the pitfalls of utilizing NAND chips for solid state drives and brilliantly architected various means to address the write performance and write endurance issues. Gnutek was purchased by STEC in 2007 and renamed the Maracite to Zues IOPs, which continues to be the worlds’ fastest and most reliable flash drive in the market. SDS continues to integrate this technology into the SpeedStor enclosure, which is built and offered by SDS for high-end I/O requirements.
In 2007 SDS partnered with DinamiQs, by offering I/O expertise during the design phase of a project that was seeking to address the scalability issues of large-scale virtual desktop infrastructure (VDI) deployments. DinamiQs created a software agent (later packaged as VitualStorm) that removes the roadblocks while also providing a central management console for fat, thin and virtual endpoints within an enterprise. After several successful deployments of this solution in Europe, SDS became the exclusive North American distributor of VirtualStorm in April of 2009.
VirtualStorm is presently represented and integrated via an elite group of SDS partners. VirtualStorm partners are the experts in large-scale infrastructure design and deployment. All are top VMWare certified partners, storage experts, and VDI veterans.
Prior to SDS founder, Linda LaPorta, spent over 20 years in the Enterprise Storage industry. As a co-founder of Baydel North America, LaPorta helped to introduce the concept of RAID technology to the industry and introduced the world’s first cached RAID 3 technology in 1990. Years ahead of its time, in terms of performance and reliability, the Baydel RAID technology became a standard for many Fortune 500 accounts.
