Registers and RAM: Crash Course Computer Science #6
 
12:17
Take the 2017 PBS Digital Studios Survey: http://surveymonkey.com/r/pbsds2017. Today we’re going to create memory! Using the basic logic gates we discussed in episode 3 we can build a circuit that stores a single bit of information, and then through some clever scaling (and of course many new levels of abstraction) we’ll show you how we can construct the modern random-access memory, or RAM, found in our computers today. RAM is the working memory of a computer. It holds the information that is being executed by the computer and as such is a crucial component for a computer to operate. Next week we’ll use this RAM, and the ALU we made last episode, to help us construct our CPU - the heart of a computer. *CORRECTION* In our 16x16 Latch Matrix graphic, we inadvertently left off the horizontal row access line above the top row of latches. As a result, the highlighted line for the row at address 12 should actually be one line higher.

The Central Processing Unit (CPU): Crash Course Computer Science #7
 
11:38
Take the 2017 PBS Digital Studios Survey: http://surveymonkey.com/r/pbsds2017. Today we’re going to build the ticking heart of every computer - the Central Processing Unit or CPU. The CPU’s job is to execute the programs we know and love - you know like GTA V, Slack... and Power Point. To make our CPU we’ll bring in our ALU and RAM we made in the previous two episodes and then with the help of Carrie Anne’s wonderful dictation (slowly) step through some clock cycles. WARNING: this is probably the most complicated episode in this series, we watched this a few times over ourselves, but don't worry at about .03Hz we think you can keep up.

How Computers Calculate - the ALU: Crash Course Computer Science #5
 
11:10
Take the 2017 PBS Digital Studios Survey: http://surveymonkey.com/r/pbsds2017. Today we're going to talk about a fundamental part of all modern computers. The thing that basically everything else uses - the Arithmetic and Logic Unit (or the ALU). The ALU may not have to most exciting name, but it is the mathematical brain of a computer and is responsible for all the calculations your computer does! And it's actually not that complicated. So today we're going to use the binary and logic gates we learned in previous episodes to build one from scratch, and then we'll use our newly minted ALU when we construct the heart of a computer, the CPU, in episode 7. *CORRECTION* We got our wires crossed with the Intel 4004, which we discuss later. The 74181 was introduced by Texas Instruments in 1970 but appeared in technical manuals around 1969. The design of the 74181, like most of the 74xx/74xxx series, was an open design which was manufactured by many other companies - Fairchild was one such manufacturer. They produced a chip, the Fairchild 9341, which was pin-for-pin compatible with the 74181. Fairchild was the first to prototype an ALU, building the Fairchild 4711 in 1968 - a one-off device not optimized for scale manufacturing. In 1969, Signetics came out with the 8260, which they marketed in a very limited sense (it was attached, AFAICT, to one particular computer, the Data General SUPERNOVA). TI follows afterwards (March 1970) with the 74181, coupled with the 9341 from Fairchild. The 74181 became the standard number for this part, and was available from many manufacturers (back in those days, chip makers cross-licensed designs all over the place in order to provide assurance that their part could be sourced from multiple manufacturers).

How a CPU Works
 
20:42
Uncover the inner workings of the CPU. Author's Website: http://www.buthowdoitknow.com/ See the Book: http://amzn.to/1mOYJvA See the 6502 CPU Simulation: http://visual6502.org/JSSim/index.html For anyone annoyed by the breaths between speaking, try this unlisted version with edited audio: https://www.youtube.com/watch?v=IkdBs21HwF4 Download the PowerPoint file used to make the video: https://docs.google.com/file/d/0BzwHNpicSnW0cGVmX0c3SVZzMFk The CPU design used in the video is copyrighted by John Scott, author of the book But How Do It Know?. There are a few small differences between the CPU in the video and the one used in the book. Those differences are listed below but they should not detract from your understanding of either. CONTROL UNIT - This component is called the Control Section in the book. It is called Control Unit here simply because that is a more common name for it that you might see used elsewhere. LOAD INSTRUCTION - In this video, what's called a LOAD instruction is actually called a DATA instruction in the book. The Scott CPU uses two different instructions to move data from RAM into the CPU. One loads the very next piece of data (called a DATA instruction in the book) and the other uses another register to tell it which address to pull that data from (called a LOAD instruction in the book). The instruction was renamed in the video for two reasons: 1) It might be confusing to hear that the first type of data we encounter in RAM is itself also called DATA. 2) Since the LOAD instruction from the book is a more complex concept, it was easier to use the DATA instruction in the video to introduce the concept of moving data from RAM to the CPU . IN and OUT INSTRUCTIONS - In the Scott CPU, there is more involved in moving data between the CPU and external devices than just an IN or an OUT instruction. That process was simplified in the video to make the introduction of the concept easier. ACCUMULATOR - The register that holds the output of the ALU is called the Accumulator in the book. That is the name typically used for this register, although it was simply called a register in the video. MEMORY ADDRESS REGISTER - The Memory Address Register is a part of RAM in the book, but it is a part of the CPU in the video. It was placed in the CPU in the video as this is generally where this register resides in real CPUs. JUMP INSTRUCTIONS - In the book there are two types of unconditional JUMP instructions. One jumps to the address stored at the next address in RAM (this is the one used in the video) and the other jumps to an address that has already been stored in a register. These are called JMP and JMPR instructions in the book respectively. MISSING COMPONENT - There is an additional component missing from the CPU in the video that is used to add 1 to the number stored in a register. This component is called "bus 1" in the book and it simply overrides the temporary register and sends the number 1 to the ALU as input B instead. REVERSED COMPONENTS - The Instruction Register and the Instruction Address Register are in opposite positions in the diagrams used in the book. They are reversed in the video because the internal wiring of the control unit will be introduced in a subsequent video and keeping these registers in their original positions made that design process more difficult. OP CODE WIRING - The wires used by the control unit to tell the ALU what type of operation to perform appear near the bottom of the ALU in the video, but near the top of the ALU in the book. They were reversed for a similar reason as the one listed above. The wiring of the ALU will be introduced in a subsequent video and keeping these wires at the top of the ALU made the design process more difficult.

What is RFID?  How RFID works?  RFID Explained in Detail
 
10:10
In this video, RFID (Radio Frequency Identification) Technolgy has been explained. So, in this video, what is RFID, what is inside this RFID system, how RFID works, and application of RFID have been explained. What is RFID? RFID is technology which works on radio frequency and it is used for the auto-identification for the different object. The RFID system mainly consists of two parts. 1) RFID Reader or Interrogator 2) RFID Tags In this RFID system, this RFID reader continuously sends radio waves of a particular frequency. If the object, on which this RFID tag is attached is within the range of this radio waves then it sends the feedback back to this RFID reader. And based on this feedback, RFID reader identifies the object. RFID tags: Now, three different kinds of RFID tags are commercially available. 1) Passive tags 2) Active tags 3) Semi-passive tags These passive tags do not have any power supply. They used to get their power from the incoming radio waves from the Readers. While active tags have a power source for their internal circuitries. And for sending the response to the reader also, it uses its own power supply. In the case of semi-passive tags, they have a power supply for internal circuitries, but for sending the response it relies on the radio waves received from the Reader. Operating Frequency: This RFID system is mainly operated in three frequency bands. 1) LF: Low-Frequency band 2) HF: High-Frequency band 3) UHF: Ultra High-Frequency band The exact frequency of operation varies from country to country. Operating Principles: Most of the RFID systems operate on any of this two principles. 1) Load Modulation 2) Backscattered Modulations Applications of RFID: 1. Institutions: Library, Hospitals, Schools, and Colleges 2. Transportation and Logistics 3. Access Control 4. Sports 5. Animal Tracking Timestamps for the different topics in the video is given below: 0:40 What is RFID? 1:56 What is inside this RFID chip? 4:42 Operating Frequencies for the RFID Systems 5:27 Working Principle of RFID Systems This video will be helpful to everyone in understanding the concept of RFID Technology.

9 Proofs You Can Increase Your Brain Power
 
05:28
The human brain is probably the most mysterious organ in our body. Scientists keep learning new facts about its work, but it still hides lots of secrets. There are a few simple ways to boost your intellect and improve your brain power, and they will surely surprise you! TIMESTAMPS Chronic lack of sleep worsens memory 0:40 Prolonged stress destroys the brain 1:07 Love and hate have a lot in common 1:29 The brain is sensitive to dehydration 1:53 Pregnancy changes the brain’s structure 2:13 The abundance of sugar reduces the ability to learn 2:39 Romantic love and maternal feelings are very similar 3:25 Painting improves the work of the brain 3:58 Reading trains the brain 4:33 SUMMARY - During a full night’s sleep, brain cells remove toxic compounds dangerous to our brain. - A decrease in memory, in the ability to learn, in self-control — these are the consequences that chronic stress is fraught with.  - British scientists found out that love and hate originate in similar brain areas.  - Our brain is almost 80% water. - Scientists proved that pregnancy reduces the amount of gray matter in the brain areas responsible for social cognition and the ability to understand other people.  - The abundance of fructose in the diet slows down the brain and reduces its ability to learn, remember information, and concentrate.  - According to brain activity, romantic relationships and maternal feelings are very similar, but there are differences as well. - A study showed that painting and contemplation of works of art improve the interaction between brain areas while slowing its aging. - Oxford scientists proved that the process of reading trains the cognitive abilities of the brain. It also activates areas that aren’t used at other times.

Learning from Bacteria about Social Networks
 
01:04:56
Google Tech Talk (more info below) September 30, 2011 Presented by Eshel Ben-Jacob. ABSTRACT Scientific American placed Professor Eshel Ben-Jacob and Dr. Itay Baruchi's creation of a type of organic memory chip on its list of the year's 50 most significant scientific discoveries in 2007. For the last decade, he has pioneered the field of Systems Neuroscience, focusing first on investigations of living neural networks outside the brain. http://en.wikipedia.org/wiki/Eshel_Ben-Jacob Learning from Bacteria about Information Processing Bacteria, the first and most fundamental of all organisms, lead rich social life in complex hierarchical communities. Collectively, they gather information from the environment, learn from past experience, and make decisions. Bacteria do not store genetically all the information required to respond efficiently to all possible environmental conditions. Instead, to solve new encountered problems (challenges) posed by the environment, they first assess the problem via collective sensing, then recall stored information of past experience and finally execute distributed information processing of the 109-12 bacteria in the colony, thus turning the colony into super-brain. Super-brain, because the billions of bacteria in the colony use sophisticated communication strategies to link the intracellular computation networks of each bacterium (including signaling path ways of billions of molecules) into a network of networks. I will show illuminating movies of swarming intelligence of live bacteria in which they solve optimization problems for collective decision making that are beyond what we, human beings, can solve with our most powerful computers. I will discuss the special nature of bacteria computational principles in comparison to our Turing Algorithm computational principles, showing that we can learn from the bacteria about our brain, in particular about the crucial role of the neglected other side of the brain, distributed information processing of the astrocytes. Eshel Ben-Jacob is Professor of Physics of Complex Systems and holds the Maguy-Glass Chair in Physics at Tel Aviv University. He was an early leader in the study of bacterial colonies as the key to understanding larger biological systems. He maintains that the essence of cognition is rooted in the ability of bacteria to gather, measure, and process information, and to adapt in response. For the last decade, he has pioneered the field of Systems Neuroscience, focusing first on investigations of living neural networks outside the brain and later on analysis of actual brain activity. In 2007, Scientific American selected Ben-Jacob's invention, the first hybrid NeuroMemory Chip, as one of the 50 most important achievements in all fields of science and technology for that year. The NeuroMemory Chip entails imprinting multiple memories, based upon development of a novel, system-level analysis of neural network activity (inspired by concepts from statistical physics and quantum mechanics), ideas about distributed information processing (inspired by his research on collective behaviors of bacteria) and new experimental methods based on nanotechnology (carbon nanotubes). Prof. Ben-Jacob received his PhD in physics (1982) at Tel Aviv University, Israel. He served as Vice President of the Israel Physical Society (1999-2002), then as President of the Israel Physical Society (2002-2005), initiating the online magazine PhysicaPlus, the only Hebrew-English bilingual science magazine. The general principles he has uncovered have been examined in a wide range of disciplines, including their application to amoeboid navigation, bacterial colony competition, cell motility, epilepsy, gene networks, genome sequence of pattern-forming bacteria, network theory analysis of the immune system, neural networks, search, and stock market volatility and collapse. He has examined implications of bacterial collective intelligence for neurocomputing. His scientific findings have prompted studies of their implications for computing: using chemical "tweets" to communicate, millions of bacteria self-organize to form colonies that collaborate to feed and defend themselves, as in a sophisticated social network. This talk was hosted by Boris Debic, and arranged by Zann Gill and the Microbes Mind Forum.

CC Music Player V2
 
02:39
I want to give a thanks to Mariusmivw for helping me out with this project. The reason I made this in 1.2.5 is primarily because I looked briefly at how to send signals in the newer versions of CC to note blocks, and it seemed that I'd need to place a computer next to every note block. If there are any other ways to do this in the newer versions of CC, I'd gladly hear them. If you're interested in making this yourself, you can find the code for the Master computer here: https://github.com/MyNameIsTrez/Tekkit-Classic---Creative-2-World---Computer-Programs/blob/master/2/startup You'll also need the code for the Slave computers: https://github.com/MyNameIsTrez/Tekkit-Classic---Creative-2-World---Computer-Programs/blob/master/3/startup The code for every Slave computers is pretty much identical, you only need to change the string in the first line to the instrument you want it to play. The choices are: 'bass1', 'bass2', 'snare1', 'snare2'. 'hat1', 'hat2', 'bassdrum1', 'bassdrum2', 'harp1' and 'harp2'. Detailed explanation: The subtitles say that the pitch is sent to the Slave computer, which converts it to the correct colored cable color, but it's a simplified and wrong way of explaining a more complex process. The pitch in the song data array is not the actual pitch of the note block, but the amount of times you need to right click a note block. This makes it easier to program the songs, since most note block tutorials on YouTube tell you the amount of times you need to right-click, and not the pitch. A note block that's placed down starts with a pitch of 1, so if the 'right-click' value in the song data array is 14, the actual pitch of the note block will be 15. This 'right-click' value is taken, and is checked for it's value. If it's higher than 15 (so a pitch of 16), the instrument that goes with it will get a '2' after it's name and the 'right-click' value will get 16 subtracted by it and 1 added to it to compensate for the earlier offset of 1. If it's equal to 15 or lower than it will get a '1' after it's name and the 'right-click' value will get 1 added to it to compensate for the earlier offset of 1. The 'right-click' value now corresponds to the pitch, and a colored cable color will be requested based on this pitch. The reason we subtracted the 'right-click' value by 16 if it was greater than 15 is to make sure the final 'right-click' value would always range between 1-16, as there are only so many colors. All the colored cable colors of one instrument type for one message to send are then all combined into a number and stored as the color cable color. This step is necessary to make sure a computer is able to output more than 1 signal at once. The instrument now has a number at the end of it's name and will be sent, and the Slave computer that has it's instrument type equal to the sent instrument will receive the colored cable color value. This value is then divided back into the correct colors by ComputerCraft automatically. Finally, the Slave computer will send (a) redstone signal(s) to the wanted colored cable color(s), which stays on for 0.1 seconds. This is needed to make sure the signal always has the time to reach the note block and power it, at a delay of 0.05 seconds it often doesn't work. Afterwards, it turns off it's redstone signal.

Natural Language Processing: Crash Course Computer Science #36

Today we’re going to talk about how computers understand speech and speak themselves. As computers play an increasing role in our daily lives there has been an growing demand for voice user interfaces, but speech is also terribly complicated. Vocabularies are diverse, sentence structures can often dictate the meaning of certain words, and computers also have to deal with accents, mispronunciations, and many common linguistic faux pas. The field of Natural Language Processing, or NLP, attempts to solve these problems, with a number of techniques we’ll discuss today. And even though our virtual assistants like Siri, Alexa, Google Home, Bixby, and Cortana have come a long way from the first speech processing and synthesis models, there is still much room for improvement.

Information about microprocessor and personal computers ,information and communication technology A microprocessor is a computer processorthat incorporates the functions of a central processing unit on a single integrated circuit(IC),[1] or at most a few integrated circuits.[2]The microprocessor is a multipurpose, clockdriven, register based, digital-integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors operate on numbers and symbols represented in the binary numeral system. The integration of a whole CPU onto a single chip or on a few chips greatly reduced the cost of processing power, increasing efficiency. Integrated circuit processors are produced in large numbers by highly automated processes, resulting in a low per-unit cost. Single-chip processors increase reliability because there are many fewer electrical connections to fail. As microprocessor designs improve, the cost of manufacturing a chip (with smaller components built on a semiconductor chip the same size) generally stays the same. Before microprocessors, small computers had been built using racks of circuit boards with many medium- and small-scale integrated circuits. Microprocessors combined this into one or a few large-scale ICs. Continued increases in microprocessor capacity have since rendered other forms of computers almost completely obsolete (see history of computing hardware), with one or more microprocessors used in everything from the smallest embedded systems and handheld devices to the largest mainframes and supercomputers.

INTROSPECT BIO Resonance Analysis

WWW.INTROSPECT-EU.COM About Oberon Diagnostic The non-lined diagnostic system (NLS) Welcome to "Oberon Diagnostic" Medical equipment place. The non-lined diagnostic system (NLS) It is the first time that advanced information technologies in the field of active homeostasis control are being introduced into the world market. The research workers have made a breakthrough in the development of information preparations for the correction of the disturbed homeostasis balance within the body and the neutralization of environmental and infectious pathological agents. This is the most super active homeostasis control program in the world today. The researchers at the Institute were the first to succeed in producing this most effective equipment that is capable of tuning to the frequency of the master pulses automatically without human intervention, as well as, detecting and correcting defects and pathologies in organs and body cells on its own. This is achieved through a combination of different specifically modulated magnetic oscillations recorded on a matrix. The fundamental concept in the development of this equipment was the hypothesis that the human body has an electromagnetic information framework that is able to respond to external radiation. They then dealt with homeopathy and Chinese acupuncture with its further elaborations by Folle, Morell and Schimmel; the Indian Yaju-Veda and the charkas spin theory; phytotherapy and many other methods of healing. Theoretical and experimental work that has made it possible to produce the OBERON system - a nonlinear quantum generator - which was initiated by Nikola Tesla, a man of genius in electronics at the end of the nineteenth century. The NLS method of analysis developed at the Institute of Practical Psychophysics makes an evaluation of the organ's condition directly due to the resonance amplification of the radiation signal of the organ under investigation using a non-invasive trigger sensor. Every organ and every cell has its own distinctive oscillations which are stored in the computer memory and can be displayed on screen as a graph, which represents the conditions of the information exchange between the organ (tissue) and the environment. Every pathological process also has its own distinctive graph stored in the computer memory with all the progressive stages shown with age, sex and other variations taken into account. After reading the frequency characteristics of the researched biological object, the system compares the degree of their spectral similarity with healthy, and pathologically affected tissue, or infection agents, to obtain the closest pathological process or tendency. In case of combined processes a virtual diagnostics mode can make a different diagnostics for each process. WWW.INTROSPECT-EU.COM

Temporary Data Storage -- Random Access Memory
 
03:26
Temporary Data Storage -- Random Access MemoryRAM chips find their main application as temporary storages for digital information, various code arrays, data tables, and individual digits. RAM stores information and ensures rapid access to such information for further processing, writing into non-volatile memory (ROM, magnetic tapes) or for any other application. If information was written into RAM but it was not further read out, such information makes no sense as it will disappear when power is off.RAM chips differ by the data read/write procedure. They fall under two types:- RAM or random access memory (this is the most flexible scheme);- Serial access memory (more specific type).Parallel or random access memory is the simplest design; generally, it requires no additional components as memory chips are designed exactly for this mode. This mode allows writing information to any RAM address and reading information from any RAM address on a random basis.However, parallel access requires rather complex sequences of all input memory signals. That is, in order to write information, RAM has first to generate the address code for a cell to be written and then send required data along with CS and WR control signals. Similarly, in order to read out written information, it has to send the full address code for a cell to be read out.Serial access memory provides for simpler memory processes. In order to write information, the memory chip has to send the code of data to be written along with the writing strobe. In order to read out information, it sends the reading strobe and access the data.Such an approach has an obvious shortcoming. You can not write or read out cells with random addresses on a random basis.Series access memories come in three main types. They include:- First in- first out memory (FIFO);- Last in - first out (LIFO) pushdown stack memory;- Data array memoryThe first 2 memory types provide for the alternate memory reading/writing procedures. FIFO memory delivers data in the same order as they were written while LIFO memory does the same in the reverse order. Data arrays are stored in memory in bulk. That is, first a large data array is written to memory in whole; then this array is read out in whole. Such a memory may also support either FIFO or LIFO principle.

A look into the microcosmos — invisible to the human eye — begins with a "storm of signals", from which the image must be computed first. The film shows the transformation of the various dimensions of data. At the beginning is the physical interaction between the measuring probe, or the light-beam, and the surface. This information is transformed into an analogue electronic signal, converted into a stream of digital data, and stored in a numerical matrix. The highlight of this process is the three-dimensional representation of the surface: the object seems to be close enough to be touched... On the "flight" back to the macroscopic world, the different representations of the signals change so rapidly that it is almost impossible to distinguish between individual images. The intention is to present the aesthetic structures of the surface (computer chip) and, in addition, the various types of signals, for although they appear to vary greatly, they contain the same information.

China's first mind-controlled car has been developed in Tianjin
 
00:37
China's first mind-controlled car has been developed by researchers in the north-east port city of Tianjin. Chinese researchers have developed what they say is the country's first car that uses nothing but brain power to drive. The research team from Nankai University, in the north-eastern Chinese port city of Tianjin, has spent two years bringing the mind-controlled vehicle to reality. By wearing brain signal-reading equipment a driver can control the car to go forward, backwards, come to a stop, and both lock and unlock the vehicle, all without moving their hands or feet. Researcher Zhang Zhao told Reuters the equipment comprises 16 sensors that capture EEG (electroencephalogram) signals from the driver's brain. They developed a computer programme that selects the relevant signals and translates them, enabling control of the car. "The tester's EEG signals are picked up by this (brain signal-reading) equipment and transmitted wirelessly to the computer. The computer processes the signals to categorise and recognise people's intention, then translates them into control command to the car. The core of the whole flow is to process the EEG signals, which is done on the computer," said Zhang. Associate Professor Duan Feng, from the university's College of Computer and Control Engineering, led the project. He emphasised that the technology is aimed at better serving human beings, and that it might soon be possible to combine brain controlled technology and driverless cars, such as the Google Self Driving Car (SDC).

Scientists Have Managed To Store Light As Sound For The First Time
 
02:00
A team of researchers from the University of Sydney has managed to convert the digital information carried by light waves into sound waves inside a microchip. This is the first time such a feat has been achieved. This technological breakthrough is crucial in the development of photonic integrated circuits, the basis of computers that use light instead of electrons to manage and store data. If successful, these systems would not be subjected to electromagnetic interference, produce too much heat, or consume too much energy. They sound great, so what’s the issue? Well, light is great for telecommunication because it’s fast, but it’s too fast for computers to process. As reported in Nature Communications, the researchers were able to build a chip that slows down light by turning it into sound waves. "The information in our chip in acoustic form travels at a velocity five orders of magnitude slower than in the optical domain," said project supervisor Dr Birgit Stiller in a statement. "It is like the difference between thunder and lightning." Light is already used in telecommunication but when its signals get to our electronic devices the data is passed onto electrons. Many companies are investigating the possibility of moving onto pure photonic microchips. There have been several attempts at this but so far no architecture has been successful in delivering a stable and usable chip. The new design might turn out to be the right approach to bring photonic computers a step closer to reality. "Our system is not limited to a narrow bandwidth. So unlike previous systems this allows us to store and retrieve information at multiple wavelengths simultaneously, vastly increasing the efficiency of the device," explained Stiller. While managing heat might be just a minor nuisance for the everyday user, it is of key importance for anyone with server farms or supercomputers needing to take into account a vast amount of waste heat. Switching to photonic systems would make this a lot more manageable. "This is an important step forward in the field of optical information processing as this concept fulfills all requirements for current and future generation optical communication systems," added co-author Professor Benjamin Eggleton. It looks like the photonic devices will bridge the gap between current models and the quantum computers of the future.

One Button Machine : Automated Feature Engineering
 
02:07
IBM Research - Ireland's Cognitive Data Science team are working on a project called "One Button Machine" for automated feature engineering. A key step in data science projects is the transformation of raw data into features that can be used as inputs for machine learning models. Often the raw data are stored across various tables in a relational database and need to be combined in various ways. This process is called feature engineering. Besides data curation, this is the most tedious and time-consuming data science task. In our One Button Machine project, we build a system which automates the feature engineering process at the “push of a button”. The One Button Machine traverses the graph defined by the entities (tables) and relations (primary/foreign keys) of a relational database. Along the graph traversal, the One Button Machine computes aggregate features that can be used as input for machine learning models. Visit: http://www.research.ibm.com/labs/ireland/

Bytecoin (BCN) intro
 
00:40
FOR FREE TRADING SIGNALS JOIN US ON TELEGRAM http://t.me/cryptopointsignals What is Bytecoin? Bytecoin is a private, decentralized cryptocurrency with open source code that allows everyone to take part in the Bytecoin network development. Privacy and security come naturally from using Bytecoin. The best solution for those who want to keep their financial privacy. Instant private transactions are provided all around the world by the Bytecoin Network, they are totally untraceable, and they don’t require any additional fees. Fiat currencies are assigned to specific territories while Bytecoin is bound to the Internet and therefore is international by default. Bytecoin Specifics Your can participate in the operation of the network by allocating the computing power of your computer. Due to this mechanism, transaction processing is decentralized, which allows a person to be not only a user, but also a participant. The decision entirely your choice, you are able to choose to take part in network maintenance and get a reward for it, or buy BCN directly on exchanges. Bytecoin Transactions Unlike fiat money transactions, where your money is processed through an intermediary, bank, or financial institution, transactions between Bytecoin users are carried out over the Internet which makes the transactions much more reliable. Transaction privacy is protected by secure cryptographic algorithms whereby no one can identify who sent the money, who the receiver was, and what amount of money was transferred. Safety and Reliability The reliability of Bytecoin is defined by the total computational power of all the computers that take part in the processing of transactions. The greater the processing power, the more reliable the network. In so doing all of the money stored in your wallet is already protected during the transaction process and its safety doesn’t depend on the network’s reliability. Your money is always safe. Deflation Bytecoins are gradually getting more expensive over time, since the emission is limited to 184.47 billion BCN. The number of Bytecoin emitted each 120 seconds is slightly decreasing. As a result BCN gains value and the exchange rate increases. While currencies with sharp decreases of reward per block are exposed to intense declines in network power, Bytecoin emissions are decreasing slowly, which protects the currency from economic shocks. Emission The emission of fiat currencies is a closed process where an issuer is engaging in its own capabilities. One can’t take part in the emission process. Bytecoin emission is an open process which employs the computing powers of all network members. Any user can join the Bytecoin network and take part in the emission process (thus, becoming a miner). Mining in the network results in the creation of new money, which serves as a reward for users who employ their computing power in order to process transactions. All transactions are carried out every 120 seconds. The Miners ensure that the transactions are processed correctly and provide cryptographic protection of transactions and personal data. However, miners cannot access users' financial data since Bytecoin protects the identity of the sender and the receiver, and conceals the sum transferred.

Neuron-Spectrum.NET: EEG reviewing and editing
 
11:14
Neuron-Spectrum.NET — software for EEG recording and analysis video guide. Subscribe: http://bit.ly/addneurosoft The "Neuron-Spectrum" software provides the EEG recording on any digital EEG system of Neuron-Spectrum series by 8 -- 32 channels (up to 64 digital derivations). During the recording monopolar, bipolar or mixed montages in "10-20" and "10-10" schemes can be used. Any polygraphic channels (ECG, EMG, EOG, breath (airflow, chest and abdominal movements), breath noise (snoring), body position, limb movement, SpO2*, etc.) can be included in montage. The montage can be switched at any moment: before the recording, during the recording, in the process of EEG review and analysis after the recording. It is possible to set different parameters for the different channels. For example, if you can not delete the trend of EEG isoline in frontal derivations, you can specify the more high values of high pass filter only for these derivations. You can change the parameters of any channel in the process of the recording. In split-screen mode you can observe the process of the recording in one part of the screen and review the recorded EEG in the other one. The software allows performing the functional tests which are standard for EEG checkups (photic stimulation, auditory stimulation, hyperventilation, eyes opening). Besides, you can perform other functional tests of any duration and in any sequence. The flexible possibilities of stimulators programming are available. You can watch the process of EEG recording both from the computer connected to the digital EEG system or computer connected to the same local network. After EEG recording termination, EEG can be reviewed in the "as recorded" mode as if it emulates the paper record. EEG Storage The records are stored in the database which provides the advanced possibilities of structuring and search. The records archives can be stored on CD or DVD. If necessary to review the archive record, the software will inform the user of the required disk to be installed in the disk drive. Besides, the records can be stored not only on the computer connected to the digital EEG system but also on any remote computer (file server). The software operates with standard network database via GDT and HL7 interfaces. EEG Printing EEG with standard grid, derivations names, recording parameters can be printed on any computer printer. In the process of the recording you can mark EEG fragment which will be printed just after the recording termination. EEG Analysis The records can be analyzed with the use of the most modern techniques of mathematical analysis. Any fragment of the record or the whole record (with the division on epochs) can be processed. As far as the digital EEG systems of Neuron-Spectrum series allow EEG recording not only in 35 Hz standard range but also in the wider frequency range, then not only standard ranges (alpha, beta, delta and theta) but also any ranges specified by the user can be analyzed at spectral analysis. Brain Mapping. The software allows mapping of practically any parameter: EEG amplitude and spectrum power in the whole frequency range, EEG amplitude and spectrum power in the specified frequency ranges, rhythm index, etc. Search of spikes and sharp waves is done automatically. In the result of search the software provides the list of the detected phenomena and mapping of these phenomena distribution on scalp. The software provides the possibility of EEG coherent and cross-spectral analyses performing and coherence maps generating. After EEG mathematical analysis the software allows creating the automatically generated EEG description in checkup report. Besides, the doctor can edit the report at her/his discretion, add any pictures and graphs. At that you can use structured comprehensive glossary which can be enlarged.

HOW NLS-Bioscaner works  INTROSPECT
 
03:15
About Oberon Diagnostic The non-lined diagnostic system (NLS) Welcome to "Oberon Diagnostic" Medical equipment place. The non-lined diagnostic system (NLS) It is the first time that advanced information technologies in the field of active homeostasis control are being introduced into the world market. The research workers have made a breakthrough in the development of information preparations for the correction of the disturbed homeostasis balance within the body and the neutralization of environmental and infectious pathological agents. This is the most super active homeostasis control program in the world today. The researchers at the Institute were the first to succeed in producing this most effective equipment that is capable of tuning to the frequency of the master pulses automatically without human intervention, as well as, detecting and correcting defects and pathologies in organs and body cells on its own. This is achieved through a combination of different specifically modulated magnetic oscillations recorded on a matrix. The fundamental concept in the development of this equipment was the hypothesis that the human body has an electromagnetic information framework that is able to respond to external radiation. They then dealt with homeopathy and Chinese acupuncture with its further elaborations by Folle, Morell and Schimmel; the Indian Yaju-Veda and the charkas spin theory; phytotherapy and many other methods of healing. Theoretical and experimental work that has made it possible to produce the OBERON system - a nonlinear quantum generator - which was initiated by Nikola Tesla, a man of genius in electronics at the end of the nineteenth century. The NLS method of analysis developed at the Institute of Practical Psychophysics makes an evaluation of the organ's condition directly due to the resonance amplification of the radiation signal of the organ under investigation using a non-invasive trigger sensor. Every organ and every cell has its own distinctive oscillations which are stored in the computer memory and can be displayed on screen as a graph, which represents the conditions of the information exchange between the organ (tissue) and the environment. Every pathological process also has its own distinctive graph stored in the computer memory with all the progressive stages shown with age, sex and other variations taken into account. After reading the frequency characteristics of the researched biological object, the system compares the degree of their spectral similarity with healthy, and pathologically affected tissue, or infection agents, to obtain the closest pathological process or tendency. In case of combined processes a virtual diagnostics mode can make a different diagnostics for each process. WWW.INTROSPECT-EU.COM

Image Compression . It Image Compression Technology
 
01:13
Image Compression Technology http://www.imagecompression.it/ An image is essentially a 2-D signal processed by the human visual system. The signals representing images are usually in analog form. However, for processing, storage and transmission by computer applications, they are converted from analog to digital form. A digital image is basically a 2- Dimensional array of pixels. Images form the significant part of data, particularly in remote sensing, biomedical and video conferencing applications. The use of and dependence on information and computers continue to grow, so too does our need for efficient ways of storing and transmitting large amounts of data. Image compression addresses the problem of reducing the amount of data required to represent a digital image. It is a process intended to yield a compact representation of an image, thereby reducing the image storage/transmission requirements. Compression is achieved by the removal of one or more of the three basic data redundancies: Coding Redundancy Interpixel Redundancy Psychovisual Redundancy Coding redundancy is present when less than optimal code words are used. Interpixel redundancy results from correlations between the pixels of an image. Psychovisual redundancy is due to data that is ignored by the human visual system (i.e. visually non essential information). Image compression techniques reduce the number of bits required to represent an image by taking advantage of these redundancies. An inverse process called decompression (decoding) is applied to the compressed data to get the reconstructed image. The objective of compression is to reduce the number of bits as much as possible, while keeping the resolution and the visual quality of the reconstructed image as close to the original image as possible.
