In my senior year at Iowa State, a partner and I designed and implemented an accelerator for computing Conway's Game of Life that would run on a ZedBoard Zynq SoC. Our accelerator is written in Verilog and synthesizes to the programmable logic portion of the SoC. We then leveraged Xilinx’s AXI-DMA module to stream the game to the accelerator for computation. Our design is parameterized, allowing our accelerator to scale to any available logic size. In addition, computation lanes share game states, enabling the accelerator to have nearly 1 access per unit cell.
yatml is a guide I wrote to help students at an undergraduate level in computer sciences and engineering to learn the fundemental mathematics of modern machine learning - specifically neural networks. In addition, the guide shows several examples of how to then apply these fundementals with TensorFlow and Keras. Click the link (above) to view the github page. You can also view the slides directly here.
This past semester I started working on my senior design project, acting as my group's webmaster. The goal of the project is to design and implement a framework for developing collaboration tools for multi-actor scenarios with Microsoft HoloLens. So far, our groups has dove into the project and learned about coordinate space sharing, HoloLens gestures, manipulating 3D models in Unity and much more. This project will help a wide range of professions to communicate 3-Dimensional ideas to one another, such as in describing a new overpass to be installed on a highway, or building plans.

During my time in Dr. Baskar’s computational mechanics group, I worked on a project aimed towards enabling automated design of micropillar sequences for lab-on-a-chip applications. The project resulted in an open source application allowing users to graphically enter a desired flow pattern and compute a sequence of micropillar obstructions to achieve that pattern. We leveraged genetic algorithm optimization as a method to compute optimal pillar sequences. This work resulted in multiple research papers.
During the Spring 2015 HackISU, I worked with Gabby Ortman, Thomas Moll, and Paul Schlenker on an ambitious project involving machine learning. We discussed how we had accumulated over 8000 images of Gabby's Betta fish, Watson, and decided to build an image classifier using a convolution neural network that we named FishNet. The network was based on LeNet for digit classification, but we trained the model instead to detect if a Betta fish was in the picture. The result was a website that was able to take a photo of a fish tank every 10 minutes, then predict whether the fish was in the photo, and caption the image accordingly. Our team placed 1st in software for HackISU Spring 2015.
Over the last semester I worked on a class project to implement in VHDL a functioning Pipelined MIPS processor. Over the course of several months we designed from the ground up a working 5-stage MIPS processor core. We implemented the entire project in VHDL. The pipeline was tested with hand-assembled code implementing the bubble sort algorithm. We successfully tested our design and were able to sort lists of numbers with our processor.
Just before I started my junior year of classes I decided to get some more hands on experience with parallel computation. I ended up purchasing 5 Raspberry Pi 2s and networking them together in an MPI grid. I used MPICH for the software library. With 5 quad core Arm Cortex-A7 CPUs there is a total of 20 CPU cores available to write code for. I have run several tests and have benchmarked my cluster using MPI. I intend to use this as a learning tool to writing parallel code with MPI. I already have several software projects I plan to port to MPI and test it out on the cluster. I hope to soon build a tutorial website on how to set one up!
During the first semester of my junior year, I worked with 3 friends of mine, Thomas Moll, Kris Burney, and Kyle Fischer. We worked on a semester long project involving the use of a webapp and REST Api backend paired with a frontend mobile app with the purpose of gathering user votes to help drive the systematic design of graphical objects. The idea is that a graphic designer would come up with a product they want to design. They would define, in general terms, how this product should look. The designed would define what attributes are free to be modified and a template would be created and the project would be available to vote on. Users with the Helix mobile app would then vote on their favorite variations of the product, driving the fitness function of a backend genetic algorithm to optimize parameters. The end result is the optimal set of varied parameters presented to the original designed to incorporate to their product so as to maximize customer satisfaction.
The array consists of 512 blue LEDs soldered together from scratch. The fixture was made from LEGO parts and wired together with spare Cat5 ethernet cable. A Raspberry Pi is used to render frames for the array. The frame data is then piped over UART connection at 115200 baud to a PIC18LF45K22 MCU that acts as a display buffer. The PIC reads the frames from the UART asynchronously through interrupts. The incoming data is stored in a back buffer until one whole frame is read. This effectively creates a double buffered system that prevents frame tearing. I wrote a front end API interface for C++ as well as Python allowing users of my API to easily interface with the Display. The API essentially holds its own frame buffer that client applications can write to, then transmits the frames on command. The benefit is that it provides a layer of abstraction that hides the way the frame data is packed into a byte array. This way, applications only need to address LEDs in an (x, y, z) manner. Check out a more detailed description of the cube's construction and design here.
There have many iterations of my personal website over the years, but I finally built something worth mentioning. The website you are viewing now was written with asp.net core 2.0 as a backend, using Markdown compiled into HTML content, and Razer C# as a templating engine. You can see all the source code for my website here.
The Hackulus Rift was envisioned by Thomas Moll. During HackISU, I worked with Tom to develop a hack atop this platform to allow Leap motion integration. The Hackulus Rift is a makeshift VR headset using common materials, 2 lenses, and a Nexus 7 Tablet. Our hack consisted of rigging a server (PC) running a node.js webserver with a Leap Motion attached to it. When the Nexus 7 loaded the page, we used socket.io to pipe leap motion data from the server to the tablet. We combined this information with the accelerometer data on the tablet to render a 3D stereo view of the virtual world where the user's hands could be seen. The setup took 24 hours to put together.
For CprE 186, we picked teams and worked on a semester project. I worked with two great coders on a video game involving the Leap Motion. The main goal of the project was to gain experience in the field of statically and dynamically linked libraries. We divided our project into 3 "engines" - Graphics, Physics, and Leap Motion Input. We each took on one of the three modules, then brought them together with one static library to load them at runtime. The result was a modular design that we used to abstract away low level graphics, physics, and input calls away from the high level game. With that, we were able to make a golf like physics game atop our custom game engine. Our team name was "RDFT" so our engine was appropriately named "The RDFT Engine."
The 5x5x5 LED cube was my first large hardware project. I constructed the cube out of 5mm blue LEDs and wired it together with Cat5 cable. The hardware consisted of a 5v PIC18F45K22 MCU driving Cat4016 constant current LED drivers. The cube was broken up into 5 layers of 25 LEDs, where a single refresh cycle would multiplex the rows and give the eye a persistence of vision effect. The cube can print text, do a wave animation and more. The software was written in embedded C on the PIC MCU. This project served as a basis for the (currently) on-going 8x8x8 Cube I am working on.

Surveillance cameras are a crucial tool for maintaining security in a variety of settings. Notwithstanding, even all that cameras can once in a while produce footage that is challenging to decipher because of low resolution, unfortunate lighting, or different variables. This is where video enhancer programming comes in, permitting clients to enhance and clarify footage that could somehow be futile.
With no time wasted, let’s examine in greater detail how video enhancer software is revolutionizing surveillance footage and altering our approach to security.
What is Video Enhancer Software?
Video enhancement software is a PC program that is intended to enhance video footage, making it more clear and easier to decipher. Low-resolution footage can be enhanced, noise and distortion removed, brightness and contrast adjusted, and more with this kind of software. In the field of surveillance, where footage from security cameras may be the only available evidence in the event of a crime, video enhancer software is especially useful.
The Advantages of Video Enhancer Software for Surveillance Footage
One of the most significant advantages of video enhancer software for surveillance footage is its capacity to make surveillance footage more useful in criminal investigations. Law enforcement personnel are able to identify suspects with greater ease and obtain valuable evidence that might have been missed with unenhanced footage. By allowing security personnel to differentiate between genuine threats and false alarms brought on by poor lighting or other environmental factors, video enhancer software can also assist in the prevention of false alarms.
How Video Enhancer Software Works
Video enhancer software works by looking at video footage and tweaking the image to make it clearer and better. While some software programs use algorithms from artificial intelligence and machine learning to automatically enhance footage, others rely on manual adjustments made by the user. Normal changes made by video enhancer programming incorporate sharpening the image, removing noise and distortion, and adjusting brightness and contrast levels.
Applications of Video Enhancer Software in Various Industries
Although video enhancer software is mostly used in the surveillance industry, it can also be used in a number of other fields. Video enhancer software, for instance, can be used by filmmakers and videographers to enhance their footage and by medical professionals to enhance medical images and videos. Sports analysts and coaches can use video enhancer software to better understand game footage and make more informed decisions.
Limitations of Video Enhancer Software
Despite the fact that it can be a powerful tool, video enhancing software does have some drawbacks. For instance, even the most cutting-edge software is unable to produce detail that is not present from the original footage. Additionally, correcting some distortions, like motion blur, may be difficult or impossible. It’s also important to keep in mind that some people and businesses won’t be able to afford video enhancer software.
Video enhancer software is a powerful tool that is revolutionizing the way we approach surveillance footage. With the capacity to upgrade and explain footage that might otherwise be useless, video enhancer software is helping law enforcement officials, security work force, and different experts pursue more educated choices and get significant proof. While it has its limits, video enhancer software is a game-changing innovation that is probably going to keep developing and working on in the years to come.


Europe to launch the first node, EDRS-A, in the construction of the European Data Relay Satellite (EDRS) network, a data highway using laser-based communications to transmit information regarding natural disasters like earthquakes and floods.
The EDRS-A node will be going up into space from Kazakhstan on-board a Proton rocket, scheduled to launch tonight at 22:20 GMT (4:20 local time).
The node is to orbit the planet at an altitude of around 36,000km and contains a laser which works like a telescope, locking onto moving targets on the ground and relaying the information to users in Europe, Africa and the Atlantic sea as well as other paying customers.
EDRS is a collaboration from the European Space Agency and Airbus Defence and space.
The node is due to go up attached to the Eutelsat 9B satellite which will be used to beam TV images to Europe, such a agreement cuts down the launch costs for both operators of the satellite.
The second satellite named EDRS-C is due to be launched some time in mid-2017, with the view to launch more satellites, probably coupled to commercial craft.

As hardware gets cheaper, more and more of the value comes from software and integration. That is the Apple strategy (keeping the Mac closed) and it is not Microsoft’s strategy with the X/Box. There is no room for open source in these models. The only way for open source to compete is to stay open from top to bottom and build an ecosystem around developers. This is a variant of the Clayton Christiansen thesis. As software and hardware get sufficiently cheap, value comes from integration.
Can open source compete with integrated hardware?

The PlayStation 5 is powered by a custom system on a chip (SoC) designed in tandem by AMD and Sony, integrating a custom 7 nm AMD Zen 2 CPU with eight cores running at a variable frequency capped at 3.5 GHz. The integrated GPU is also a custom unit based on AMD’s rDNA 2 graphics architecture. The GPU has 36 compute units running at a variable frequency capped at 2.23 GHz, making it capable of a peak theoretical performance of 10 teraFLOPS. The GPU supports hardware-accelerated real-time ray tracing, a rendering technique that allows for realistic lighting and reflections.
If you are a gamer, you will be interested in the next generation of video game consoles. According to Sony, the PlayStation 5 will have the capability to run games that support 8K resolution. If you have a 4K display, you can play games at 4K. If you have a computer, you can download games on it for free. However, you won’t be able to play the games in 4K unless you have a 4K TV. The new consoles will also support VR technology. For example, you can wear a headset to play games. These headsets allow you to be immersed in virtual worlds. When you are playing a game, you can move around in it, and you can interact with your surroundings. See more now
PlayStation 5 will offer better graphics quality than the previous consoles. Its custom SoC will be much faster than the previous systems. The graphics processor in the PS5 will be built on a new architecture called AMD’s rDNA 2. The graphics processing unit of the PlayStation 5 will have a graphics core with a 36-compute unit design. This will be accompanied by the world’s first ray-tracing graphics card. It will support hardware-based ray tracing, which allows developers to create photorealistic images without using a program called a ray tracer.
It has been speculated that the PS5 will also allow users to play games without the use of a game controller.
Sony has created the PS5 to make game development easier for developers. The previous generation of consoles required a developer to write a lot of code. The PS5 will enable developers to do just that. Sony has made its own custom-built chip that will make game development easier. The PS5 chip is said to be faster than the chips on the PlayStation 4 and will also be much more powerful. The game console will have a custom GPU and custom-designed CPU to power the system. The PS5 chip will come with two dedicated computing units. It will have eight cores per compute unit, for a total of 16 cores. This will give the PS5 its much-needed performance boost.

The PS5 is expected to be released in 2020. It will have a custom SoC from AMD. This SoC is called the rDNA 2. It will be more powerful than the previous generation PS4. Its GPU will be twice as fast as the GPU in the PS4. This will make it easier for developers to create high-quality graphics. The GPU will also support hardware-based ray tracing. It will be the world’s first gaming console with ray-tracing capabilities. This feature allows developers to render scenes that look real. Developers will be able to achieve this with minimal computing power and memory. There are two types of ray tracing. One is called path tracing.


SSD pricing is slowly dropping to a reasonable price point that i argue everyone should at least have put their OS boot drive as an SSD and use traditional mechanical hard drives for large file and media storage.
My current custom built Mac Pro consist of a Plextor M5S 256GB SATA-III SSD as my main system drive and a few Western Digital Caviar Black 1TB SATA-III 7200RPM drives for storage purposes. However the SATA-III interface have quickly become the bottleneck for newer and faster SSD due to the 600MB/s max interface speed.
This is where PCI-Express(PCIe) come in. PCI Express took over PCI/PCI-X/AGP as the main expansion bus for connecting additional peripherals. Like SATA, PCIe has evolved over time and the current motherboards using new chipsets has PCIe 3.0 slots for expansion. We have been using PCIe x8/x16 (the longest slot on your motherboard) for external graphics cards, like the EVGA GeForce GTX 750 SC i use on my system.
The large amount of bandwidth that PCI-Express offers is exactly what is needed to cater for newer and faster SSDs. Newer motherboards comes with a M.2 slot that connects directly to the PCIe bus. Unfortunately, i’m using a Gigabyte H87-D3H and it does not come with a M.2 slot for native support of M.2 SSDs. It does however have an extra PCIe x4 slot that i could use, after putting the EVGA GTX 750SC on the PCIe x16 slot.
I decided on the getting the Silverstone ECM20 M.2 to PCIe x4 adapter and a Samsung SM951 512GB (AHCI) M.2 80mm PCIe x4 SSD. After my research on Hackintosh forums, the AHCI (vs NVMe version) is required for better compatibility on custom built Macs. PC users can choose the slighter faster Samsung 950 Pro 512GB PCIe NVMe M.2 SSD.
Some quick benchmarks comparing
- Western Digital 1TB Caviar Black
- Plextor M5S 256GB SATA-III SSD
- Samsung SM951 512GB M2 PCIe SSD
As my H87-D3H motherboard only supports PCIe 2.0 x4, my interface limited is about 1,500MB/s. If i upgrade to a PCIe 3.0 or a native M.2 PCIe 3.0 slot, i should be able to hit close to 2,000MB/s on the read speed, since on paper the specifications for the SM951 is “Sequential Read: 2150MB/s & Sequential Write: 1500 MB/s”.
As we can see from the graphs above:
- 256GB Plextor SATA-III SSD vs 1TB Caviar Black = 2.85x performance gain.
- 512GB SM951 PCIe SSD vs 1TB Caviar Black = 9.22x performance gain
- 512GB SM951 PCIe SSD vs 256GB Plextor SATA-III SSD = 3.2x performance gain
Still feel your computer is sluggish? Time to make that upgrade! 🙂

As the performance of personal computers is increasing, so is power consumption and emitted heat. If the very first PCs needed no coolers, the modern ones can't function without multi-watt power supplies and effective heat abstraction. It is hard to imagine a computer without power management. At first, the external power management interface was granted through BIOS interruptions. The next step was APM (Advanced Power Management) specification. It existed for a while.
But as the computers and operating systems are becoming too complex, controlling the machine through BIOS interruptions becomes unpractical, as it decreases the performance. So the obsolete specifications such as Plug and Play, MPS and APM have been replaced by ACPI. ACPI (Advanced Configuration and Power Interface) is an open industry specification co-developed by Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. It defines every aspect of power management, even for 64-bit PC components.
Any modern computer (whether it's a server, workstation or a laptop) most likely fully complies with the ACPI specification. This makes ACPI support crucial for a contemporary operating system.
eComStation supports ACPI 3.0. To get ACPI support, the whole operating system had to undergo certain changes:
- the kernel has been updated and modified;
- device drivers have been updated, too;
- several utilities are now being developed.
The introduction of ACPI support caused dramatic eComStation update
Inside the ACPI driver there's an "ACPI virtual machine", developed by Intel Corporation. Computer configuration data is represented in the object form (devices and methods applied to devices). By executing small programs within the virtual machine, we control the computer (devices as objects, events and response to them).
ACPI Manager utility provides graphical user interface to the ACPI virtual machine.
ACPI Manager lets us see the computer's devices and control them (on/off, state change, status query). For instance, you can switch off the coolers by executing "Off" method for the "Fan" type devices. Or find out the temperature ("Therm" devices).
ACPI driver: Initializes Your Computer
When eComStation with ACPI support boots, the following steps are performed:
- proper initialization of all devices: if a device is in the sleep mode, put it in the active mode; if a device needs an address and IRQ, it gets the resources required.
- multiprocessor systems launch: detecting the number of CPUs, gathering data for SMP-kernel, APIC (Advanced Programmable Interrupt Controller) controllers initialization.
ACPI driver: Multi-core Computers
Multi-core systems are the state of the art these days. With the help of ACPI, eComStation can get the most out of the home/office Intel Core Duo and AMD X2 based machines, not only multiprocessor servers.
ACPI driver: Power Management
Using ACPI and APM together is more flexible and brings more advantages than using APM alone. To use all ACPI functions, drivers and programs will have to call ACPI.PSD and ACPI32.DLL directly.
Main Power Management Functions:
- "Power" button pressing handling;
- power state change support;
- suspend/resume/hibernate support (for laptops as well);
- gathering data about coolers, temperature, laptop battery state;
- coolers noise level decrease;
- power saving policy setup, laptop battery life increase;
- power consumption decrease when machine is idling;
- throttling support: a "Turbo" button reincarnation, when the computer can run idle cycles (but now, the CPU has 8 states instead of 2).
ACPI.PSD can only be used with eComStation 2.0 and higher.

Excellent article! I've downplayed the necessity of ACPI thinking it was only for Laptops! I now recognize the importance of its development and understand why its development was (and still is ) such a "bucket of worms" for the people developing it for eCs.
Thanks for "Keeping up the good work!"

Things to Consider Before You Buy a Wireless Speaker
With people wanting to listen to their music everywhere they are opting to buy the wireless speakers. Even when people are at home, they’re mostly playing their music through the wireless speaker since they can move with the speakers from one room to the other. With the many brands of the wireless speakers in the market today, if you are planning to buy a wireless speaker you should not rush in buying any wireless speaker but instead research and find out the best wireless speaker that will fit your needs. You will end up buying speakers that do not fit your style and the environment when you buy the wireless speaker in a hurry. Before buying the wireless speaker, you should read the following article that has a summary of the tips that you need to consider when choosing the wireless speaker.
The first thing that you need to consider when choosing the wireless speaker is the usage. Mainly the speakers are categorized in the uses of the wireless speaker and this makes the manufacturers spend a lot of their time in designing a wireless speaker that will be used in a different environment. The environment such as being an outdoor person or an indoor person can determine the wireless speaker that you will be buying.
The quality of the speakers should also be a determiner in helping you to choose the wireless speaker. The speaker’s quality can be both the internal and the external side of the speaker. The wireless speaker which are of good quality should have the best sound. The internal things that determine the quality of the sound that is being produced by the wireless speaker are the codec, transducer, and the DSP circuit. Understand this terms before you settle for any wireless speaker. The place that the wireless speaker will be used when the owner will be playing the music will also determine the quality of the sound. Speakers that are designed to be used inside the house will also have a different look as well as sounding different when being played outside.
You need to research on the internal feature of the wireless speaker such as the battery life and the connectivity range of the wireless speaker. The things that will be big determiners of the way that you use your speakers are the connectivity range and the charge the wireless speaker can hold. Buy the speaker that has the best connectivity from the music source. To get a lot of playtime when using the wireless speaker, choose the wireless speaker that has the best battery life. To summarize, those are the factors to consider when choosing a wireless speaker.

On Tuesday, Chinese internet users condemned Elon Musk after Beijing said its space station conducted precautionary actions to prevent clashing with two of his SpaceX satellites, a setback to the tycoon’s credibility in a country that has adopted his Tesla electric automobiles.
According to a document presented to the UN’s space agency this month, China’s Tiangong space station was required to adopt preventive collision avoidance measures during two near contacts with SpaceX’s Starlink satellites in July and October.
The satellites relocated into orbits that triggered space station technicians to change course on both times, according to the document presented to the United Nations Office for Outer Space Affairs.
According to Beijing on the incident, they said
After landing a rover on Mars and sending satellites to the Moon, Tiangong — which means “heavenly palace” is the newest triumph in China’s effort of becoming a major space powerhouse.
The station’s core module was launched into orbit earlier this year, and it is scheduled to be able to run smoothly by 2022.
Chinese social media users slammed Musk and his firms over the event, with one hashtag garnering 87 million views as of Tuesday morning.
How ironic that Chinese people buy Tesla, contributing large sums of money so Musk can launch Starlink, and then he [nearly] crashes into China’s space station
A user commented
Tesla, on the other hand, continues to be highly popular in China, wherein one out of every four of its vehicles is sold. In Shanghai, the company is also establishing a remarkable entirely plant.

Title : Estimation of unidentified cognitive models with physiological data Agency : National Science Foundation Panel : Cognitive Neuroscience Location : University of California, Irvine Start date : 2017-04-01 End date : 2020-03-31 Agency code : 1658303 Project text : Link
Abstract: Estimation of unidentified cognitive models with physiological data
Understanding the role of changes in brain activity over time is extremely difficult. Moreover, relating these changes to the psychology of decision making is even more challenging, but important to understand to predict and explain behavior. In particular, brain activity can vary in relationship to the speed of a behavioral response, but these variations are difficult to measure systematically. The goal of this project is to measure brain electrical activity together with behavioral data in order to develop new methods to statistically model the relationships and to aid in detection of subtle brain changes occurring with behavior. The project will result in a new method for analyzing these complex relationships and allow for better combination of different forms of data generally. This will provide a more accurate view of the effect of experimental manipulations and treatments. All analytic procedures will be extensively documented along with the experimental data and these will be freely available online.
A crucial tool in this project is the new technique of joint modeling of behavioral and physiological data. An advantage of joint modeling that has thus far been underexploited is the capacity to construct genuine neurocognitive models that are informed by both behavioral and neural data. Indeed, joint estimation opens up the possibility to construct new models whose parameters are only estimable given more than one type of information. This project will lead to the development of a multimodal sequential accumulation model that makes predictions about the combination of reaction time, accuracy, and EEG data, and that allows for conclusions not possible from either type of data individually. Specifically, the project involves experimental studies to generate data that will, in combination with the new statistical framework, allow the disentanglement of parameters of a cognitive model that cannot be estimated without the use of both neural and behavioral data. The parametric neurocognitive model will involve specific neural markers that connect behavioral parameters to EEG activity measures. The newly collected data will also provide a direct test of the classical modeling assumption that visual encoding, decision-making, and executing a motor response are sequential processes.

The Higgs boson is the rock star of fundamental particles, catapulting CERN, the laboratory where it was found, into the global spotlight. But what is it, why does it matter, and what exactly is CERN?
In the late 1940s, a handful of visionaries were working to steer Europe towards a more peaceful future through science, and CERN, the European particle physics laboratory, was duly born. James Gillies tells the gripping story of particle physics, from the original atomists of ancient Greece, through the people who made the crucial breakthroughs, to CERN itself, one of the most ambitious scientific undertakings of our time, and its eventual confirmation of the Higgs boson.
Weaving together the scientific and political stories of CERN's development, the book reveals how particle physics has evolved from being the realm of solitary genius to a global field of human endeavour, with CERN's Large Hadron Collider as its frontier research tool.


Time Stretching Algorithms
AbstractThis research describes and implements new techniques for objective analysis and comparison of common time stretching algorithms. A set of test signals and samples is used in conjunction with spectral analysis to generate objective error measurements and subsequent comparisions of the algorithms. The time stretching techniques are treated as black-box processes, and are regarded as members within a general family of analyze-modify-resynthesize algorithms. This black-box approach of output signal analysis provides a basis for objective evaluation of the more general class of algorithms. Six common time stretching algorithms are analyzed: the classic phase vocoder, oscillator bank phase vocoder, peak tracking phase vocoder, phase-locked vocoder, synchronous overlap add technique, and overlap add technique. The six algorithms are then compared within a uniform framework to provide greater insight regarding the behavior of their output signals. Subjective listening evaluations are also performed, then all results contribute to the development of criteria that evaluate and rank the algorithms’ suitability in various signal processing situations.

Analysis ExampleIn total, this research uses six test signals in conjunction with three analysis techniques to evaluate six time stretching algorithms. The techniques and algorithms are described in detail, and 128 different graphs representing the resultant data are interpreted and comparatively discussed. This particular example was selected to briefly illustrate a facet of the research and provide a general idea of what the work is about.
1 — Test Signal
Analysis of the Phase-Locked Vocoder in this example is performed using one of the special test signals shown below. This test signal is designed to be difficult to stretch, and consists of a steady 1000 Hertz sinusoid mixed with a logarithmically swept sinusoid that moves from 50 to 21,000 Hertz.
The input signal is synthesized with a duration of two seconds and an another ideal output signal is synthesized with a duration of four seconds. This allows comparison of the ideal output signal with the stretched output signal when the Phase-Locked Vocoder is configured to stretch its input by two times. The input, ideal, and stretched signals used in this example may be heard below.
2 — Phase-Locked Vocoder
Time stretching of the input signal is performed by the Phase-Locked Vocoder developed by Miller Puckette. This algorithm is similar to the Classic Phase Vocoder, however, it produces higher fidilety results by mitigating phase errors with a technique that locks phases of adjacent bins together before resynthesis. The following formulas show its operation, starting with a Discrete Fourier Transform (DFT) that generates spectral data where X contains the spectra, w is the window function, x is the signal, H is the hop size in samples, S is the stretch factor, N is the window size in samples, and F is the number of frames:
Phase accumulation occurs next, where P contains accumulated phase, over-bar signifies the complex conjugate, and Y[f-1,k] represents the previous output spectrum:
Following phase accumulation, phases are locked together into L, with the notation k-1 and k+1 signifying bin offsets, so that phases of three adjacent bins are combined:
After adjacent phases are combined, the output spectra are calculated as Y:
Finally, the output signal is windowed and overlap-added into y:
3 — Moving Spectral Analysis
Moving Spectral Analysis was developed for this research to provide information about the behavior of a stretched signal over time. This technique affords insight about time domain features like transients or persistent amplitude modulations by comparing them to their counterparts in the ideal signal. In order to create meaningful comparisons, the signals are power-normalized according to the following equations, where x is the audio file, w is the windowing function, A is the start of the signal region, B is the end of the signal region, and R is the Root Mean Square (RMS) power value:
R is then used to perform power-normalization of the stretched file so that it matches the ideal file as shown by the following equation, where xs is the stretched file, Rs is the stretched RMS power value, Ri is the ideal RMS power value, xsr is the power-normalized stretched file, and N is the length of the file in samples:
Following normalization, Fourier analysis is used to compare the signals’ spectra, frame by frame, to create a measure of difference between the ideal and stretched versions. The first step is implemented with a DFT where X represents the output spectrum, N is the number of samples per analysis frame, w is the window function, x is the signal, H is the hop size in samples, and F is the total number of frames:
The next step is the calculation of a set of moving average magnitude values over time, or magnitude curve, according to the following equation, where M contains the magnitude curve:
The windowing function is then normalized out of the magnitude curve, and the magnitude curve is converted to sones as represented by S, shown here by the following equation:
After creating the sones curves in S, the following equation uses these curves to calculate an error curve that shows how the two signals differ. E represents the error curve, Xi is the ideal spectrum, and Xs is the stretched spectrum:
Finally, the average and maximum error values are determined according to the following equations, where Eavg is the average value of the error spectrum, and Emax is the maximum value of the error spectrum:
4 — Analysis Graphs
The following graphs show the ideal swept sinusoid signal in blue, the stretched version in green, and the error, or absolute difference, in red. Error is scaled in sones on the Y axis to more closely match our perception of sound, and the X axis displays the ideal and stretched signals over time, while also providing a more analytical representation of their differences than our ears can perceive. The upper graph is an overview of the entire signals, and the lower graphs show more detailed views of interesting areas within the signals.

You can also run into the USD or the Ethernet cable right from your media converter to that of your computer.
Thirdly, you can run the cables from the wireless router or from that of the hub and then try to connect it with any of the additional workstations with eh aid of the cable. If ever you cannot find for the options input into your workstations, then you can use the media converter then.
Lastly, you can also lead the light amount of the slack right into the table when you are to run them from a certain device right into another. You can also use the ties instead of the tape in coupling those cable together. Then, you can also power every component of the networks. If ever that it is necessary, you can install some of the important software support in order to support that of the performance.
Right before you are to decide on a certain product, it can be better for you to find out the appropriate kind of system to use. This can work well in order to support that of the performance of the network application. Try to check also that all the materials you have are complete and ready for the installation. There are services that can be used in order for you to come up with the best installation of the fiber optic. You just have to make sure that you check the services they have from the previous clients.


Apple Macbook pro is one of the portable computers with high technology and powerful apps. These notebooks are thinner and lighter. The latest model of Macbook 17 inch pro is also experiencing start up problems which has become a major issue nowadays. These problems may arise due to:
Peripheral devices could be the problem. Just check its connectivity and then try starting Macbook pro. If not, then you need to disconnect the peripheral devices and then turn it on to check everything goes well or not. By doing so, you can address the issue.
If the computer beeps more than one time or the lights are blinking, then there must be some hardware failure. Bad RAM is very common issue on newer Mac's. So, to test this case, just remove one RAM at a time and reboot. Repeat this activity again till you find the problem. If any of the culprit arises, then have a look in Mac owner Manual and install RAM.
Just check the battery level of the Macbook. To perform this task, press the battery button or on the side of your computer. Single light blinking may lead you in the condition of dead Macbook. So, you need to charge accordingly whenever necessary.
The operating system may stuck resulting in start up problems. All you need to do is to hold down the control key, command key and the power button together to restart the computer. In this scenario, try booting off an OS CD and run Disk Utility to repair the disk. If this also doesn't work, last option is to use the software like Stellar volume repair or Onyx software to repair.
Hard drive failure
A major issue is of the hard drive. If the hard drive has been corrupted or damaged or makes abnormal noises, first thing you need, is to back up your data safely and replace it immediately.
Resetting SMC is the important feature. The simple SMC reset can resolve number of failures such as battery not charging, USB ports and Bluetooth not working, fans running fast, erratic sleep mode performance, failure to response to power button, sluggish performance etc. So, to reset the SMC, first shut down the Mac, disconnect from MagSafe connecter, remove the battery and hold the power button for 10 seconds. After releasing the power button, reinstall the battery, reconnect the MagSafe connector and turn your Mac on.
Thermal sensors not working
This issue is noticed when the fans run at a higher speed but the computer does not boot. You have to ensure first, that the sensors are plugged in properly. If yes, then replace it. If this doen't fixes the problem, you need to change the logic board.
Faulty MagSafe adapter
To test that the adapter is faulty or not, one needs to check the electrical outlet and the plugs are inserted properly or not. If the outlets works smoothly, then unplug the power adapter for a while and then plug it again. By doing so, if the power adapter's LED does not light up, then definitely MagSafe is damaged.
Therefore, fixing these issue in the appropriate manner will resolve most of the start up problems of the Macbook pro.


Welcome to your pool, a place where water and electricity ALMOST go together. Pool lighting is unique in many ways. Builders try to use the fewest number of light fixtures necessary to achieve full pool luminescence. One pressing reason is that regulations require specific materials and methods for light conduit and housing installation; more materials & labor = more cost and hassle. Pool/spa lighting also requires water-tight fixtures and lenses specifically designed to spread the beam of light so that, instead of a blinding flashlight effect, the light is spread vertically and horizontally as far as possible.
This information plays a big role in LED light design, because most pool lights require large, high-wattage bulbs to achieve the fullest array of light in the pool. Until recently, replacement LED bulb sets were rare and did not achieve the desired effect. The replacements cost roughly 10 times more than incandescent bulbs and were not powerful enough to match the intensity of the 500W bulb they were replacing. Many spa lights were designed to receive halogen bulbs (mini-cam) that cannot accept any sort of LED bulb. In light of these facts, manufacturers began to design new LED fixtures that would meet or exceed the standard pool/spa light specifications while increasing energy efficiency.
Bulb replacement versus whole fixture
So, why can’t they just make something to thread into an existing fixture? Well, as mentioned above, these have been attempted – and Pentair currently makes a retro kit for their pool-size fixtures – but consider these facts. First, in order to install one of these expensive replacement kits, you have to break the water-tight seal and open your existing fixture. This may have already been done several times to replace the incandescent bulb, which increases the risk of the fixture not fully sealing after it is reassembled. Also, that fixture was designed to function with an incandescent bulb, electrically and from the standpoint of the lens and body. Therefore, it would be an expensive ordeal that may result in limited fixture life and unsatisfactory results.
New fixtures are designed specifically to power and enhance LED lighting technology.
- The body design of these fixtures (flatter versus conical and spread wide to the extremes of the diameter) allows for the fullest array of LED diodes, which helps with matching the intensity of their predecessors
- The lenses are uniquely molded to spread the beam of light across the bottom of the pool and as wide horizontally as possible
- Wholesale fixture engineering means the manufacturer can specify the exact amount of energy its fixture uses (versus the potential unknowns of replacement bulbs in high-energy-usage fixtures)
- New LED fixtures increase energy efficiency by 70-85% over standard bulbs, according to manufacturers
- Complete new fixtures offer the choice of pure white or full color LEDs with color shows
Color-changing LED lights
Whether your pool surface is white or richly colored, the water should always be clear. Therefore, at night, a color light show can be dazzling, regardless of what type of pool you have. Manufacturers of these color-changing LED light fixtures have specific solid colors and color-shifting programs built into the lights. The way an LED engine switches from one color scheme to the next is by the introduction and interruption of power to the fixture in specific sequence. So, if you have a standard light switch (on/off) for your pool or spa lights, you would follow the programming guide that comes with your fixtures, switching the lights on and off a certain number of times until you reach the color scheme you prefer. If you have relatively new automation, your system should be able to communicate with the system manufacturer’s version of LED fixture. Some Zodiac systems even communicate with many other manufacturers’ LED color-changing lights. For many control systems with older technology, there are system upgrades that can allow for color-changing lights (and variable speed pumps and other items currently in high demand).
Let’s get to work!
Replacing a fixture requires more time and presents more challenges than simple bulb-and-gasket replacement (in most cases). The fixture wiring runs in a conduit from the back of the pool wall (connected to a stainless or plastic niche) to a junction box where the wires are connected. The technician disconnects the wires from the power supply, connects a fish tape to the light cord, removes the fixture from its niche, and pulls the wire toward the pool body. Once the new fixture cord is connected to the fish tape, the process is reversed.
Sometimes this requires the technician to get in the pool; most often, it can be done from above. The only time draining a pool would be required is if the conduit has a restriction that prevents the cord from pulling freely. This is very rare, and the need would be determine case by case. Oh, and if the water is freezing, some installers would beg you to heat or drain the pool. But not ours. We’ll endure the frigid water to bring you some excellent lighting…but we may ask for some cocoa afterward.

Why Fog Computing Beats Cloud and Grid
You might have heard about Fog Computing by now if you are a Cloud and Grid Computing geek . Though not everybody is familiar with it, Fog Computing is slowly developing from a concept to something more practical — network-level architecture. Simply put, it is: a technology which enables data processing in smart devices.
In recent years, Cloud Computing has emerged as a one-stop solution for companies looking to scale their computational operations without investing in new infrastructure. It has proved to be more resourceful for businesses looking to cut down on their operational costs by offshoring their data centres to third-party cloud services.
Grid Computing, the actual parent of Cloud Computing, is architecture suited mostly to central authorities like system administrators and integrators. These are the authorities who are familiar with the operations running at system-end; they install and upgrade the servers and applications, and do all the required maintenance using specific software.
Both Cloud and Grid Computing have their specific set of limitations. They are related to hidden costs, network latency and — the most important — security and privacy. For instance: Cloud Computing is mostly criticized for its centralised models, where consumers’ data remain affixed to the whims of monopolized organizations. Furthermore, in its core model, all the applications and processing are centered entirely in the cloud.
Why Fog Computing Makes More Sense
Can we meet the growing demand for server farms as the number of connected smart devices continues to go through the roof? The answer is no. The computing technologies would always need to evolve, just like Grid evolved into Cloud.
Fog Computing could then be called the grandson of Grid Computing, the son of Cloud Computing. The reason why Fog Computing is called Fog Computing, metaphorically, is that Fog is evidently closer to the ground than Cloud is. This means that in the case of Fog Computing, all the data processing takes place at the network level, right in the smart devices.
And indeed, Fog Computing allows smart devices to be — you know — smart. So instead of processing some task using the cloud, one can use all the devices that surround us: from personal computers to smartphones, and from coffee makers to refrigerators.
SONM, a project which also places Fog Computing at the centerpiece of its development, presents an interesting case study in the same regard. The project creatively hybridizes Fog with an open-source PaaS technology named Cocaine. The funny-titled tech has a built-in locator service which helps to monitor and search services within a cluster.
“Given: you use a smartphone (4 cores, 2 GHz, 64 GB storage); half of the resources you own are not used,” the lead developer of SONM explains. “SONM container-app Docker estimates the resources which are not used. You can either provide the app with an access to all idle resources you have at any moment or limit the resources for SONM usage.”
“The devices which are close to yours (this is determined by Locator services built in SONM architecture) can use each other’s idle data and this will be a kind of cloud storage while the devices are knit geographically as well.”
With the said experiment, SONM proves that the buyers of computing power enjoy more cost-efficient solutions than any centralized cloud service can offer. The project plans to take the use cases of Fog Computing further by exploring into scientific projects, site hosting, game servers, neural networks, video rendering and computer graphics technology.
The SONM developers plan to utilize Fog Computing in solo mining, stating that miners “will stop burning [their] kilowatts for PoW mining and start serving calculations for everyone in the network.”
This means you will not have to wait too long to see the benefits of Fog Computing. Time to turn into a geek!

About electric guitar
If you are guitarist then you might have wonder about electric guitar and does it works. Playing an electric guitar is almost every guitarist dream. And when you get attaches with an electric guitar there is no coming back. So, the question "what is an electric guitar"?
>> An electric guitar is also a part of guitar family that convert the vibration of its strings into electric signals.
Working of electric guitar
In any electric guitar there is a magnetic pickup installed within its body. When the player strum the strings the vibration of strings transform electric energy into sound energy that amplified by a loudspeaker. As electric guitars makes less audible sound while strumming or plucking it requires an amplifier.
Electric guitar works on the principle of electromagnetism. If you are from science background you most probably know what I'm talking about. Well, basically change in magnetic field generates electricity. When a magnetic field is passed through a moving coil it generates electric potential. This same phenomenon is used in electric guitar.
In electric guitar there is a device installed known as pickups which help to generates electric potential. Pickups consists of magnet which are wrapped around hundreds of coils. These magnets generates a magnetic field around the strings. And when we strum the strings an electric current flows through the coils which are wrapped in the pickups. The pickup takes that vibration through an amplifier and send it to the loudspeaker. And thus we hear the sound of an electric guitar.
Types of electric guitar
There are 4 different types of guitar. They are:-
1) Solid guitar
2) Chambered guitar
4) Full hollow body
1) Solid guitar.
A solid body electric guitar is a type of electric guitar which is the most famous among the players. These guitars are generally made of hardwood such as walnut, ash, maple and even mahogany wood are used. Density of wood is also maintained which helps to increase the stability of pickups and protect from the vibration of body.
There are two brands Gibson and fender that are ruling the market from late 1930s and 1940s, and still they are at the top. But Gibson is quite expensive in the Indian market and Fender comes in the range of affordable rates.
2) Chambered guitar.
Chambered guitar also knows as semi-solid guitar. These guitar have a chambered shape deep within the body, generally comes with f-shape hole. The main purpose of making this guitar is to achieve a semi-acoustic tone. This guitar came in mid 50s and still has a good reputation in market. Ibanez AMF73 Semi-Hollow body Electric Guitar is the best example.
3) Semi-acosutic guitar.
Semi-acoustic guitar is actually an hollow-body electric guitar. This guitar was first design in 1930s. This guitar is just like an typical electric guitar with pickup installed, but it includes a sounding box or open chamber that makes it a bit different from any other electric guitar, this also makes guitar lighter in weight which catches the attention of many players.
And yeah one main thing I need to mention that don't get confused between semi-acoustic guitar and electro acoustic guitar, they both are different. Electro acoustic guitar is just an acoustic guitar which can be amplified by adding pickups in it.
The main purpose of semi-acoustic guitar is to produce a clear and warm tone which makes it more favourable for jazz players. As this guitar can be played unplugged, this made it unpopular among the rock bands or the one who love loud music. But these guitar can give the feeling of electric as well as acoustic.
Now you might have wondering if both chambered guitar and semi-acoustic guitar looks same "what is the difference between them?". Well, here is the answer.
Chambered guitar is made up of single wood which actually made to decrease the weight of guitar. It works exactly same as solid body electric guitar.
But semi-acoustic guitar are made from thin sheet of wood. These guitar can be played as acoustic guitar also at home when it is unplugged.
4) Hollow guitar.
These guitar are some kind of acoustic guitar, but the only difference is that they have have pickups installed. These guitar are introduced in 1920s and still considered as a jazz guitar. The name hollow body says the literal meaning of this guitar "it has nothing inside"(just like acoustic). There is nothing much to say about this guitar. If you like soft and warm type of music and this might be good for you.

With our RVS© portfolio we are the worldwide leading company in the area of rendezvous- and docking operations in space. Our major advantage is that we are able to support the different missions with just one hardware platform.
The beginnings of the Rendezvous- and Docking Sensors (short: RVS) go back to first experiments in the frame of the missions STS-84 and STS-86. In 1997, the prototype version of today‘s RVS had been used for the docking between Space Shuttle Atlantis and the MIR space station.
Since 2010, the RVS – and later on the RVS3000 as well – have established themselves as the standard sensor for autonomous approaches of unmanned space transporters with the International Space Station ISS.
In addition to the past missions ATV and HTV of the European Space Agency ESA and the Japanese Space Agency JAXA, Jena-Optronik‘s RVS 3000(-3D) is flying today on the American Cygnus cargo spacecraft by Northrop Grumman, as well as on Sierra Space’s Dream Chaser in the future. The US start up Axiom Space builds ist commercial space station also with support of the RVS 3000.
With the beginning of this decade, the fields of application of the RVS 3000 has been increased signifcantly with the possibility to approach also non-cooperative targets (like satellites). In the frame of the MEV-1 and MEV-2 conducted by US space company Northrop Grumman, the lifetime of the IS-901 and IS-1002 satellites could be extended for several years – thanks to our sensors and the given possibility to perform a docking with these spacecraft. Along such servicing missions for lifetime extension, the RVS3000-3D will be also used to clean up space debris, e.g. in the frame of Astroscale’s ELSA-m mission.
But also in the area of space exploration, Jena-Optronik‘s RVS portfolio is in great demand. In addition, to catching a probe with Mars material in orbit in the frame of the MSR ERO mission (Mars Sample Return – Earth Return Orbiter), astronauts will be guided by a Jena-Optronik sensor on their way to the moon when they approach and dock with the Lunar Gateway (the planned space station in the moon orbit) or the Human Landing System to go down to the moon’s surface
The possibilities to use the RVS portfolio are manifold and it is planned to extend the RVS capabilities towards a landing application in order to enable a safe landing of spacecraft on other celestial bodies, like Moon and Mars, in the future.
Moreover, we are already working on a miniaturized of our RVS, the so-called µRVS, which shall enable Rendezvous- & Docking operations that are conducted by smaller satellites and spacecraft.
