Decentralized computing is the allocation of resources, both hardware and software, to each individual workstation, or office location. In contrast, centralized computing exists when the majority of functions are carried out, or obtained from a remote centralized location. Decentralized computing is a trend in modern day business environments. This is the opposite of centralized computing, which was prevalent during the early days of computers. A decentralized computer system has many benefits over a conventional centralized network. Desktop computers have advanced so rapidly, that their potential performance far exceeds the requirements of most business applications. This results in most desktop computers remaining idle (in relation to their full potential). A decentralized system can use the potential of these systems to maximize efficiency. However, it is debatable whether these networks increase overall effectiveness. All computers have to be updated individually with new software, unlike a centralised computer system. Decentralised systems still enable file sharing and all computers can share peripherals such as printers and scanners as well as modems, allowing all the computers in the network to connect to the internet. A collection of decentralized computers systems are components of a larger computer network, held together by local stations of equal importance and capability. These systems are capable of running independently of each other.

India will soon start calling bids to install a 13-kilowatt hour (GWh) grid-scale battery storage system in Ladakh. The plan, advertised as largest global tender for a 13 gigawatt-hours (GWh) grid-scale battery storage system and efforts towards installation of a large green energy capacity of 10 GW in the region.
New and renewable energy minister Raj Kumar Singh said that the electricity generated by the ministry will be supplied to other parts of the country through transmission links. Singh further said that the transmission system that has been set up in that 13000 megawatt-hours (MWh) of storage is added in Ladakh.
A battery capacity of 1 GWh (1,000 MWh) is sufficient to power 1million homes for an hour and around 30,000 electric cars.
As per reports, government has plans to develop Ladakh into a strategic region. The electricity generated by systems that have not yet been built will be used to supply electricity to the residents of Leh and Kargil districts as well as defense facilities.
Further Singh said, “Our strategic intent is entirely the climate, the environment. We are world leaders in climate action. We will cement our position as world leaders in climate action. It will be green energy round the clock from Ladakh.”
The storage and transmission component of the project is expected to cost ₹34,000 crore. Meanwhile, the government also plans to call bids to build a grid-scale battery storage system of 4GWh at local load dispatch center.


Learning through touch
A sense of touch is a vital aspect of this learning process. Just like humans learn better through touch and interaction, robots benefit greatly from it too. Thanks to a haptic device, which simulates the sense of touch for the teacher, robots can now learn and improve their skill by interacting with its environment. Otherwise, it would struggle to perform tasks effectively. When it can interact with its surroundings through touch, it becomes successful in carrying out various actions, like flipping a pancake, demonstrating the power of incorporating touch in the learning process.


With a conventional film-based method, the images are recorded on films and cannot be further manipulated for brightness and magnification. With digital mammography, the images are captured by an advanced state-of-the-art detector and digitally stored on high resolution computers. The data can then be viewed, manipulated for optimal contrast and brightness and magnified.
Our digital mammography has a large digital plate to facilitate more precise imaging of larger breasts, making full use of the large detector of the system. The large size of the detector enables imaging of all breast sizes and there is no need to take additional images in most instances. The study is performed in a painless manner with minimal compression of the breasts.
In younger patients and patients with dense breasts, image analysis has been made more easier. There is a full-field magnification capability for every image. This will curtail the need to bring back patients for magnification.

Rakon clarifies nature of exports
24 August 2005
Comment from No WARP! on today's Rakon media release (below) - while it may be technically correct that "Rakon has not developed any technology specifically for the US military. No technology has been specifically developed by Rakon for use in smart bombs or missiles", their comment that the company is "not privy to the end-use systems, equipment or applications developed by its customers" reveals either a startling level of irresponsibility or of duplicity. A 2003 Investment NZ publication describes them thus: "Rakon manufactures GPS-enabled, temperature-compensated quartz crystal transistors used for ultra-demanding applications such as aircraft navigation, satellite communications and smart munitions." Perhaps Investment NZ knows more about them than they do themselves?
Media release from Rakon
New Zealand technology exporter Rakon says no government grant money it has received has been used to develop products supplied to military or aerospace customers.
Managing Director Brent Robinson said these customers accounted for around one per cent of the company's manufacturing output.
He said that the company respected the commercial confidentiality of its contracts with customers, and was not privy to the end-use systems, equipment or applications developed by its customers.
Media headlines that Rakon was involved in supplying missile systems to the US were incorrect and misleading, said Mr Robinson.
"Rakon has not developed any technology specifically for the US military. No technology has been specifically developed by Rakon for use in smart bombs or missiles."
Rakon manufactures quartz crystals and oscillators that provide a timing reference in a variety of applications, such as cellular phones, GPS systems and other communications equipment.
The company won this year's New Zealand Trade and Enterprise export award. It is a leading New Zealand technology exporter whose customers include North American, European and Korean communications equipment manufacturers.

The security of the Internet of Things is at stake
It has been quite a while since the end of 2018. And that is why in the news you can still see a whole stream of companies that show the figures of the past year. Gemalto Corporation was one of the last to follow this trend. The organization recently published a report in which it confirmed that the use of blockchain technology to protect Internet of Things (IoT) devices doubled in 2018. A recent survey published by the company confirms that usage has increased from 9% in 2017 to 19% in 2018.
The numbers are striking given the fact that the past year was one of the hardest for the industry. The company interviewed 950 experts from the technology and business industry around the world to collect data for its research. In the course of the survey, the corporation found that 23% of people believe that blockchain can be an ideal option for the development of the IoT sphere. Another interesting conclusion is that 91% of companies that have not yet used blockchain in their activities are ready to consider the possibility of its implementation in the future. In addition, 90% of organizations believe that IoT device security is a fundamental feature for the buyer. 79% of respondents also believe that the authorities should develop regulatory measures to enhance the safety of equipment.
How about the security of the Internet of Things?
Jason Hart, CTO for Data Protection at Gemalto, took the opportunity to talk about the state of blockchain regulation during the presentation of the survey results. He confirmed that there was a great need for clarity in the control of the industry. According to him, businessmen are starting to be under pressure because of data protection. He believes that investment in additional security measures is much more important for the market now.
The issue of IoT device security is really acute. For example, in the late December 2018, analysts of Nokia Corporation presented the Cybersecurity Threat Intelligence Report 2019. According to him, in 2018 IoT botnets reached 78% (of all cyber threats) — twice as much as in 2016. Experts assume that in 2019 the figures will only grow. By the way, in November, Bosch released equipment capable of collecting data of Internet of Things devices in real time and selling them on the market of data IOTA, the company said in a press release. The giant telecom China Mobile also distinguished itself with its presentation of the value of blockchain technologies in everyday life. The company introduced the IoT module and chip embedded in the water purifier, which will register and send data to producers and suppliers for which users will receive tokens. However, despite all the positive aspects of the technology, its implementation is still in very early stages. This means that there are many opportunities for growth, but at the same time it implies a lack of regulation.


Koenigsegg has always been at the forefront of supercar innovation, creating some of the most extreme and advanced vehicles in the world. Now, the Swedish company has introduced the Gemera, a four-seat hybrid supercar that combines luxury, practicality, and performance. This big daddy exotic features a unique electric motor with out-of-this-world specs.
Christened Dark Matter, it’s a raxial flux motor that Koenigsegg has developed in-house. It is a new type of electric powerplant that blends axial and radial flux technologies to achieve high torque and power density. The motor also has six-phase winding, which reduces current ripple and increases efficiency.
But what makes the Dark Matter truly remarkable is its construction. The motor uses carbon fiber for both the rotor and the stator, as well as the housing. This makes it extremely light and strong, weighing only 86 pounds but producing 800 hp and 922 lb-ft of torque. Koenigsegg claims this is the world’s first carbon-fiber rotor and stator structure.
The Gemera offers two powertrain options, both of which include the Dark Matter motor. The first option is the LSTT (Light Speed Tourbillon Transmission), a four-wheel drive system with four-wheel torque vectoring that can be powered by either the Dark Matter motor or a twin-turbo TFG engine, or a combination of the two. The TFG engine is a 2.0-liter three-cylinder engine that delivers 1,700 hp and 2,581 lb-ft of torque.
The second option is the HV8, which elevates the Gemera to a new level of performance. It replaces the TFG engine with a 4.0-liter V8 engine that generates 1,500 hp and 1,828 lb-ft of torque. The HV8 option also uses the Dark Matter motor, resulting in a total output of 2,300 hp and 2,750 lb-ft of torque – a new world record for a production car.
The Gemera also has a sophisticated battery pack that uses a special dielectric oil to cool the cells directly. The battery pack has a capacity of 15 kWh and can provide a range of 31 miles in electric mode. The car also has a silicon-carbide inverter named David that can handle 1,300 Amps AC at 850 V DC.
The Gemera is not only a technological marvel but also a luxurious and practical hypercar. It can accommodate four adults comfortably, with ample space for luggage and personal items. It also has a host of features, such as four-wheel steering, adaptive suspension, active aerodynamics, wireless charging, biometric sensors, and an advanced infotainment system.
The Gemera is expected to start deliveries in early 2025, with a price tag of $2.6 million. Only 300 units will be produced, making it a rare and exclusive vehicle. Koenigsegg has once again proven its ability to create groundbreaking and stunning supercars that challenge the limits of engineering and design. The icing on the cake is the high output, low mass
Darth Vadar Dark Matter electric motor. Just think of a smaller version of this motor for an e-bike…

|Title:||Altering the polarity of self-assembled carbon nanotubes stationary phase via covalent functionalization|
|Authors:||Hussain, Chaudhery Mustansar|
|Abstract:||We present for the first time that self assembled carbon nanotubes (CNTs) can be functionalized to alter their polarity and chromatographic behavior. The nanotube phase was synthesized via ethanol chemical vapor deposition (CVD) and functionalized by acid oxidation. Compared to an equivalent CNT column, the functionalized nanotubes (f-CNTs) showed strong retention and enhanced separation for polar organics such as alcohols, where the capacity factor increased by more than 100%, and the number of plates per metre increased by as much as 60%. The f-CNTs phase showed classical chromatographic behavior and good reproducibility. This is an important first step toward the development of diverse functionalized CNT columns.|

- NASA Chief Technologist Douglas Terrier spoke at The Shard
- He believes that AI is the most important development in human history
- Autonomous robots likely to travel further than any human can
- AI will be an integral part of our lives both socially and in business
NASA Chief Technology Officer Douglas Terrier told a packed out WBS London at The Shard that AI is the most important development in human history.
And Dr Terrier, who is NASA’s principal advisor on technology, revealed AI will play a huge role as the US space agency explores deep into our solar system in the coming years, with autonomous robots likely to travel further than any human can.
Dr Terrier, who has been working in partnership with Loizos Heracleous, Professor of Strategy, on NASA’s future strategic direction, said: “AI will pass human intelligence very soon - within decades. Many people have warned about the consequences of this and the likely loss of jobs, but we at NASA see this as a remarkable opportunity.
“Of course it is something we need to pay attention to. History has shown that it is not the largest but the smartest thing on the planet that dominates the food chain, so we should be careful if we are not the smartest on the planet soon.
“But AI will be an integral part of our lives both socially and in business, it will be the most fundamental change in human history. Machine augmentation is ubiquitous in our lives already and our digital transformation team at NASA is looking at how we can get ahead of the curve.
“However, the rate of technology change is so rapid now. In my lifetime technology advances have gone from decades to products being obsolete in a year-and-a-half – some firms are not even taking out patents because they know they will soon be obsolete.”
AI technology was used in NASA’s Mars probe Curiosity and is set to guide its new robotic explorer InSight, which is currently on its way to the red planet and is due to land in November, as it drills into the planet’s crust and looks to detect marsquakes.
Moreover, a new study by NASA’s Jet Propulsion Laboratory predicts autonomous robots will be crucial for exploring the farther reaches of our solar system as spacecraft will often be out of communication of Earth, so they will have to make decisions by themselves and navigate their way back.
And Dr Terrier believes this advanced technology will trickle down to help wider society on earth.
“NASA’s technology and innovations have always benefited humans on earth,” said Dr Terrier. “The technology we use to recycle water, even perspiration, on the International Space Station is now being used in countries with severe water shortages. It will be the same for our AI technology.”
The recent launch of Warwick Business School’s AI Innovation Network will investigate how artificial intelligence can be used to take on some of the world’s biggest challenges.
“This is a smart move,” said Dr Terrier. “All businesses are going to have to get their heads around AI and how it will impact on their sector. Machine intelligence and its ability to extract value from big data will be fundamental to any business being competitive.
“My nine-year-old son’s generation will be the first generation in history to have evidence of life on another planet and work with intelligent machines.
“Half of the jobs for him have not been invented yet, so how does a business compete in that sphere? People talk about strategic agility, but the answer is there is no model that can deal with this rapid change.”
Dr Terrier detailed how NASA’s role is now to encourage the growth of the commercial space sector by contracting out cargo flights to re-supply the ISS to the likes of SpaceX and Orbital ATK, with plans for private firms to be used to take astronauts to ISS in the future.
That leaves NASA the job of investing in the “pointy tip of space exploration” where a commercial market has not developed yet, such as putting humans on Mars.
“The space industry is now worth $348 billion, and this is just the ground floor,” said Dr Terrier. “NASA can now concentrate on building the largest ever space craft to take humans to the moon and then Mars.
“And launching next year is the James Webb space telescope. In the past it was a bipolar space race, but now we collaborate internationally, and this will be launched on an Ariane space rocket built by the European Space Agency. It will have 100 more times resolution than the Hubble telescope, so we will be able to see within a few million years of the ‘big bang’.
“The growth of the space industry is a win-win for NASA, as we have a host of new partners like SpaceX and it allows us to invest in incredibly exciting new technologies and missions.”

The Virtual Space, which manufactures smartphone-based virtual reality (VR) headsets in Africa, is calling on individuals, companies and organisations to help grow its Pioneer VR Education Kit, which is an early step towards providing affordable VR education for all. The kit is used in classrooms with Google Expeditions, allowing teachers to control the experience while learners view the VR content via their headsets.
The headsets are designed and made in South Africa and can be produced with printed branding and in custom colours. The company believes that virtual reality is going to offer a range of experiences and knowledge to many people that they would not get any other way. They believe the impact of VR on education will be as big as the impact of the internet has been.
In addition to educational purposes, these headsets offer more control over the variables and provision of a reliable and customised service to clients in Africa. The VR systems are a one-stop solution for those looking to include VR as a drawcard at promotional events. VR provides the unique ability to give event-goers an exciting experience in the limited space available at a display stand.


NUMERICAL ANALYSIS AND SCIENTIFIC COMPUTING
Multiscale Modeling and Computation
Multiscale modeling and computation is a rapidly evolving area of research in computational science and engineering such as material science, chemistry, fluid dynamics and biology. For example, natural porous media have extreme heterogeneity which requires multiscale modeling and computation. Moreover, most of the differential equations encountered in physics embody some sort of conservation law. It is therefore important to try to ensure that the method chosen to solve the equation obeys the underlying conservation law exactly. We introduced a new class of locally conservative methods and analyzed for second-order elliptic equations. As in the discontinuous Galerkin finite element method, we try to combine the finite element and finite volume methods by incorporating the governing equation in a sense closer to the finite volume method.
Modeling and Optimal Control of infectious disease
Our model for influenza is based on the standard SLIAR, a deterministic compartmental model, where S, L, I, A, and R denote the numbers of individuals in the susceptible, latent, infective, asymptomatic, and recovered compartments, respectively. Parameter values used in the model include initial population of each compartment, fatal rate, latent period, ratio of asymptomatic, basic reproduction number, contact rate, and contagiousness. We added controls of vaccination, antiviral treatment and isolation and related parameters such as effect and cost of those control measures to compare and/or evaluate various control strategies. Then we applied optimization theory to find optimal control in each setting of objective functional. We performed numerical simulations with various set of parameters to investigate the effect of control measures. We also observed the change of optimal strategies according to the change in parameters and objective. 30% was vaccinated during 100-130 days after the initial time and infective individuals reduce their contact rate by 20%. Optimal control depends on the choice of mathematical models, estimation of parameters, objective controls. For example, when the costs of controls are different, the optimal strategy tends to reduce the use of an expensive treatment. Effective strategy also changes corresponding to parameter values including fatal rate, latent period, ratio of asymptomatic, basic reproduction number, contact rate, and contagiousness, which represent the disease characteristics. While the details of optimal strategy changes according to each setting, some qualitative advice suggested by the various runs is consistent, e.g. early vaccination, if available, is an essential tool in fighting an epidemic.

Lung Monitoring in EIT using Finite Element Method
Admitting fundamental limitations of EIT methods in providing high resolution image for the interior region away from the boundary, it would be desirable to pay attention to high resolution impedance image in a near-surface region. Lately, we propose a new EIT system that has a unique electrode configuration and associated data collection method. In this new system, two pairs of driving electrodes are attached on the four sides of the surface of the body, and an array of many voltage-sensing electrodes is attached on the surface as shown in figure below. The advantage of the separation of current injection and voltage sensing electrodes is that no current flows through the contact impedance of a voltage sensing electrode and therefore the contact impedance contributions on measured voltage values are negligible. When we inject current using a pair of driving electrodes, the induced internal current will flow underneath the voltage sensing electrodes, and we can measure voltages between equipotential lines in the normal direction to the voltage sensing electrode array.
A finite element eddy-viscosity method for turbulence model
It is generally accepted that incompressible fluid flows, even for high values of the Reynolds number are faithfully modeled by the Navier-Stokes system. The direct computational simulation of the Navier-Stokes system in turbulent regimes is a formidable task due to the disparate scales that have to be resolved. Turbulence modeling attempts to mitigate this situation by somehow accounting for the effects of small-scale behavior on those at large-scales without explicitly resolving the small scales. One such approach is to add viscosity to the problem; the Smagorinsky and Ladyzhenskaya models and other eddy-viscosity models are examples of this approach. In 1969 and 1970, Ladyzhenskaya proposed a turbulent model and the Smagorinsky model corresponds to the special case. Unfortunately, these approach usually results in over-dampening at the large scales, i.e., large-scale structures are unphysically smeared out. To mitigate this fault of eddy-viscosity modeling, filtered eddy-viscosity methods that add the artificial viscosity only to the high-frequency modes were developed in the context of spectral methods by using the damping operator Q, which is called a high-pass filter. This research applies the filtered eddy-viscosity idea to finite element methods with hierarchical basis functions and the existence and uniqueness of the finite element approximation has been proved. Its convergence to a weak solution of the Navier-Stokes system also has been analyzed.
Superconvergent discontinuous Galerkin methods
Optimal therapy protocols for HIV infection
We developed an age-structured model of HIV infection with various compartments, including target cells, infected cells, viral loads and immune effector cells, to provide a better understanding of the interaction between HIV and the immune system. We show that the proposed model has one uninfected steady state and several infected steady states. We conduct a local stability analysis of these steady. In addition, we study various techniques and ideas from optimal control theory to derive optimal therapy protocols. The results of numerical simulations indicate that the optimal therapy protocols can facilitate long-term control of HIV through a strong immune response after the discontinuation of the therapy.
FOSLL* Approach for Nonlinear Partial Differential Equations
The first-order system LL*(FOSLL*) method was first used in Newton-FOSLS iterations to improve mass conservation of Navier-Stokes problem. It is known that the least-squares finite element method typically provides poor conservation in fluid motion because it minimizes the continuity equation in L2-norm instead of using exact discrete mass conservative form. However, by using FOSLL* with a modification of normal vectors in Newton iteration instead of FOSLS at the last iterate, mass loss was greatly improved. While getting improved mass conservation by using FOSLL* only at the last stage of Newton iterations, questions arose what happens if FOSLL* was used in several stages in Newton iterations and how this process can be generalized. The difficulties in applying FOSLL* in Newton iterations and the generalization are being studied currently.
Nonlinear Mixed FEM and Adaptivity
The mixed finite element method has two important features. It conserves the mass locally and produces accurate flux even for highly non-homogeneous media with large jumps in the physical properties. Compared with existing literature, several improvements are made in this work on mixed methods for nonlinear elliptic problems. First, the Raviart-Thomas-Nedelec finite element space of all orders including the lowest order case are treated. Existence and uniqueness of the approximate solution to the model problem is proved.


The wave form will look something like what is shown below. Press Esc to cancel. In this article we explain how to do PWM (Pulse Width Modulation) control using arduino. With this “Output compare match” principle we can accomplish different tasks. This 613 will be saved to variable t2 (low time). The result will be a square wave with high time = 387 uS and low time = 613 uS and the time period will be always 1000uS. In both circuits shown above the arduino is supposed to be powered through the 9V external power input jack.
A 50% duty cycle signal, for instance, would have the same repeating on time and off time. I found 1000uF worked well for this frequency. We have explained PWM in this tutorial using 2 examples which will help you learn how to control LED brightness using PWM and how to control DC motor speed using PWM. LED brightness control using arduino. This will allow us to control the transistor from an off state with no current flowing to a state where only a few milliamps of current flow or to a state where we have several amps of current flowing through the transistor. Motor is connected as collector load to the transistor. And if so, does R1 have to be changed at all? We can determine the PWM output voltage by using the following formula, PWM voltage=(Duty cycle ÷ 256) x 5 V. 256 because akin to the 0 to 1 levels available with digital signals, we have 256 levels of analog values that we can work with.
Note that there are separate digital pins available on arduino UNO for pwm which means these pins can give pwm output. All Rights Reserved.

3, 5, 6, 9, 11. For example you can control the brightness of an LED or the speed of a motor by changing the […] Output a variable pwm (pulse width modulation) signal and so on. This is because of interactions with the millis() and delay() functions, which share the same internal timer used to generate those PWM outputs. Which lower down the frequency to 9.9 Hz and since we want to remain in the bracket of 10 to 100Hz so we can not go more high. Where TON is the time for which the square wave is high and TOFF is the time for which the square wave is low.When duty cycle is increased the power dropped across the load increases and when duty cycle is reduced, power across the load decreases. In the circuit diagram, slider of the potentiometer is connected to analog input pin A0 of arduino. The block diagram of a typical PWM power controller scheme is shown below. Best to start with the preset value at zero the first time you try this just in case! we have plane to develop an Inveter using PWM principle, please assist me to develop it with your much needed ideas. I hope my intentions were made clear and if you could help, that would be much appericated. By selecting bits COM1A1,COM1B1. DC motors usually consume much more than this and it is not safe to directly connect a heavy load to the digital pin. In the circuit, the slider of the 50K potentiometer is connected to analog input pin A0 of the arduino. Greetings Sirs If you are new to electronics, we have a detailed article explaining pulse width modulation. 5V because that’s the maximum power you can send via an Arduino Uno. Keep this in mind while selecting the motor. e.g 255 for 8 bit, 1023 for 10 bit, 8191 for 13 bit operation.
The current will be limited by the MOSFET only and it will dissipate any excess power as heat. regards
CircuitsToday.com is an effort to provide free resources on electronics for electronic students and hobbyists. I've preset this value in the setup() to 3240 which is just below the value where the MOSFET starts to turn on. Here the brightness of an LED can be controlled using a potentiometer. Other Arduino Boards. On the Arduino Mega, it works on pins 2 - 13 and 44 - 46. To change the number of PWM steps you change the value of ICR1. PWM Tutorial for Arduino, ESP8266 and ESP32 In this tutorial we focus on Pulse Width Modulation (PWM) for the Arduino, ESP8266 and ESP32 microcontroller. I hope 0.0113 makes sense now. PWM waves with various duty cycle are shown in the figure below. Arduino reads the voltage at the analog input pin A0 (slider of the POT). Pwm is also one of the factors that make arduino a simplest development board, as pwm can be done by adding just one line code to your program. I would like to have a little give though with the transistor, so that if I later get a fan with a slightly higher wattage, it wont burn out the system; hence want to switch from the 800mA limit on the 2n2222a.

The code is well commented and fairly simple. space is limited so i will be using the arduino micro. In TCCR1A set the mode of the timer. For the EBG structure,how to get the attenuation result by using HFSS? The output pulse width should be adjustable , you can use an analog pin voltage varying from 0-5 V for duty cycle control (0 V should correspond to 0 duty cycle and 5V should correspond to 100% duty cycle). Controlling the LED brightness using arduino and motor speed control using arduino. Controlling the LED brightness using arduino and motor speed control using arduino. I am going to output a variable frequency pwm signal on Pin-9 of arduino board. +5V supply for the potentiometer can be taken from the 5V regulator output on the arduino board. The working of the program is very simple. Its just a value to remain in 10000 to 100000 bracket. The duty cycle of this wave form will be (387/(387+613))*100 which is equal to 38.7%.

A passive crossover A bi-amplified system with an active crossover Used in multi-driver speaker systemsthe crossover is an assembly of filters that separate the input signal into different frequency ranges i. Hence the drivers receive power only at their operating frequency the sound frequency range they were designed forthereby reducing distortion in the drivers and interference between them. The ideal characteristics of a crossover may include perfect out-of-band attenuation at the output of each filter, no amplitude variation "ripple" within each passband, no phase delay between overlapping frequency bands, to name just a few.
Crossovers can be passive or active. A passive crossover is an electronic circuit that uses a combination of one or more resistorsinductors, or non-polar capacitors. These components are combined to form a filter network and are most often placed between the full frequency-range power áttekintés a gyógyszer bactefortról and the loudspeaker drivers to divide the amplifier's signal into the necessary frequency bands before being delivered to the individual drivers.
Passive crossover circuits need no external power beyond the audio signal itself, but have some disadvantages: they may require larger inductors and capacitors due to power handling requirements being driven by the amplifierlimited component availability to optimize the crossover's characteristics at such power levels, etc.
Unlike active crossovers which include a built-in amplifier, passive crossovers have an inherent attenuation within the passband, typically leading to a reduction in damping factor before the voice coil  An active crossover is an electronic filter circuit that divides the signal into individual frequency bands before power amplification, thus requiring at least one power amplifier for each bandpass.
Any technique that uses crossover filtering followed by amplification is commonly known as bi-amping, tri-amping, quad-amping, and so on, depending on the minimum number of amplifier channels. In car audio systems, passive crossovers may be in egyéb paraziták az időbeli bambuszrostból separate box, necessary to accommodate the size of the components used.
Passive crossovers may be simple for low-order filtering, or complex to allow steep slopes such as 18 or 24 dB per octave. Passive crossovers can also be designed to compensate for undesired characteristics of driver, horn, or enclosure resonances,  and can be tricky to implement, due to component interaction.
The changes are matters of concern for many in the hi-fi world. Active crossovers may be simple circuits that emulate the response of a passive network, or may be egyéb paraziták az időbeli bambuszrostból complex, allowing extensive audio adjustments. Some active crossovers, usually digital loudspeaker management systems, may include electronics and controls for precise alignment of phase and time between frequency bands, equalization, dynamic range compression and limiting control.
The cabinet is narrow to raise the frequency where a diffraction effect called the "baffle step" occurs. Most loudspeaker systems consist of drivers mounted in an enclosureor cabinet. The role of the enclosure is to prevent sound waves emanating from the back of a driver from interfering destructively with those from the front.
The sound waves emitted from the back are ° out of phase a pinworm tünetei a testben those emitted forward, so without an enclosure they typically cause cancellations which significantly degrade the level and quality of sound at low frequencies.
The simplest driver mount is a flat panel i. However, in this approach, sound frequencies with a wavelength longer than the baffle dimensions are canceled out, because the antiphase radiation from the rear of the cone interferes with the radiation from the front. With an infinitely large panel, this interference could be entirely prevented. A sufficiently large sealed box can approach egyéb paraziták az időbeli bambuszrostból behavior.
A sealed enclosure prevents transmission of the sound emitted from the rear of the loudspeaker by confining the egyéb paraziták az időbeli bambuszrostból in a rigid and airtight box. Techniques used to reduce transmission of sound through the walls of the cabinet include thicker cabinet walls, lossy wall material, internal bracing, curved cabinet walls—or more rarely, visco-elastic materials e.
However, a rigid enclosure reflects sound internally, which can then be transmitted back through the loudspeaker diaphragm—again resulting in degradation of sound quality.
This can be reduced by internal absorption using absorptive materials often called "damping"such as glass woolwool, or synthetic fiber batting, within the enclosure. The internal shape of the enclosure can also be designed to reduce this by reflecting sounds away from the loudspeaker diaphragm, egyéb paraziták az időbeli bambuszrostból they may then be absorbed.
Other enclosure types alter the rear sound radiation so it can add constructively to the output from the front of the cone. Designs that do this including bass reflexpassive egyéb paraziták az időbeli bambuszrostból, transmission line, etc. To make the transition between drivers as seamless as possible, system designers have attempted to time-align or phase adjust the drivers by moving one or more driver mounting locations forward or back so that the acoustic center of each driver is in the same vertical plane.
This may also involve tilting the face speaker back, providing a separate enclosure mounting for each driver, or less commonly using electronic techniques to achieve the same effect.
These attempts have resulted in some unusual cabinet designs. The speaker mounting scheme including cabinets can also cause diffractionresulting in peaks and dips in the frequency response. The problem is usually greatest egyéb paraziták az időbeli bambuszrostból higher frequencies, where wavelengths are similar to, or smaller than, cabinet dimensions. The effect can be minimized by rounding the front edges of the cabinet, curving the cabinet itself, using a smaller or narrower enclosure, choosing a strategic driver arrangement, using absorptive material around a driver, or some combination of these and other schemes.
Horn loudspeakers[ edit ] A three-way loudspeaker that uses horns in front of each of the three drivers: a shallow horn for the tweeter, a long, straight horn for mid frequencies and a folded horn for the woofer Main article: Horn loudspeaker Horn loudspeakers are the oldest form of loudspeaker system.
The use of horns as voice-amplifying megaphones dates at least to the 17th century,  and horns were used in mechanical féreg elleni gyógyszerek 5 éves gyermekeknél as early as Horn loudspeakers use a shaped waveguide in front of or behind the driver to increase the directivity of the loudspeaker and to transform a small diameter, high pressure condition at the driver cone surface to a large diameter, low pressure condition at the mouth of the horn.
The size of the throat, mouth, the length of the horn, as well as the area expansion rate along it must be carefully chosen to match the drive to properly provide this transforming function over a range of frequencies every horn performs poorly outside its acoustic limits, at both high and low frequencies.
The length and cross-sectional mouth area required to create a bass or sub-bass horn require a horn many feet long.
Some horn designs not only fold the low frequency horn, but use the walls in a room corner as an extension of the horn mouth. In the late s, horns whose mouths took up much of a room wall were not unknown amongst hi-fi fans. Egyéb paraziták az időbeli bambuszrostból sized installations became much less acceptable when two or more were required. A horn loaded speaker can have a sensitivity as high as dB at 2.
This is a hundredfold increase in output compared to a speaker rated at 90 dB sensitivity, and is invaluable in applications where high sound levels are required or amplifier power is limited.
Transmission line loudspeaker[ edit ] Main article: Transmission line loudspeaker A transmission line loudspeaker is a loudspeaker enclosure design which uses an féreghajto tabletta embernek ara transmission line within the cabinet, compared to the simpler enclosures used by sealed closed or ported bass reflex designs. Instead of reverberating in a fairly simple damped enclosure, sound from the back of the bass speaker is directed into a long generally folded damped pathway within the speaker enclosure, which allows far greater control and use of speaker energy and the egyéb paraziták az időbeli bambuszrostból sound.
Two-way binding posts on a loudspeaker, connected using banana plugs. A 4-ohm loudspeaker with two pairs of binding posts capable of accepting bi-wiring after the removal of two metal straps. Most home hi-fi loudspeakers use two wiring points to connect to the source of the signal for example, to the audio amplifier or receiver.
To accept the wire connection, the loudspeaker enclosure may have binding postsspring clips, or a panel-mount jack. This typically causes monophonic material in a stereo recording to be canceled out, reduced in level, and made more difficult to localize, all due to destructive interference of the sound waves.
The cancellation effect is parazita szervezet környezete noticeable at frequencies where the loudspeakers are separated by a quarter wavelength or less; low frequencies are affected the most.
This type of miswiring error does not damage speakers, but is not optimal for listening.

Higher-priced and higher powered sound system cabinets and instrument speaker cabinets often use Speakon connectors. Speakon connectors are considered to be safer for high wattage amplifiers, because the connector is designed so that human users cannot touch the egyéb paraziták az időbeli bambuszrostból.
Main article: Wireless speaker HP Roar Wireless Speaker Wireless speakers are very similar to traditional wired loudspeakers, but they receive audio signals using radio frequency RF waves rather than over audio cables. There is normally an amplifier integrated in the speaker's cabinet because the RF waves alone are not enough to drive the speaker. This integration of amplifier and loudspeaker is known as an active loudspeaker.
Manufacturers of these loudspeakers design them to be as lightweight as possible while producing the maximum amount of audio output efficiency. Wireless speakers still need power, so require a nearby AC power outlet, or possibly batteries. Only the wire to the amplifier is eliminated. Specifications label on a loudspeaker Speaker specifications generally include: Speaker or driver type individual units only — Full-rangewoofer, férgek táplált kezelése, or mid-range.

Voice-coil diameter may also be specified. If the loudspeaker has a compression horn driver, the diameter of the horn throat may be given. Rated Power — Nominal or even continuous powerand peak or maximum short-term power a loudspeaker can handle i. A driver may be damaged at much less than its rated power if driven past its mechanical limits at lower frequencies. Each of these situations might pass more energy to a tweeter than it can survive without damage.
Elsewhere, the variety of meanings for power handling capacity can be quite confusing. Impedance — typically 4 Ω ohms8 Ω, etc.

Frequency response — The measured, or specified, output over a specified range of frequencies for a constant input level varied across those frequencies.
It sometimes includes a variance limit, such as within "± 2. Sensitivity — The sound pressure level produced by a loudspeaker in a non-reverberant environment, often specified in dB and measured at 1 meter with an input of 1 watt 2. Manufacturers often use this rating in marketing material.
Maximum egyéb paraziták az időbeli bambuszrostból pressure level — The highest output the loudspeaker can manage, short of damage or not exceeding a particular distortion level.
Manufacturers often use this rating in marketing material—commonly without reference to frequency range or distortion level. Electrical characteristics of dynamic loudspeakers[ edit ] Main article: Electrical characteristics of dynamic loudspeakers The load that a driver presents to an amplifier consists of a complex electrical impedance —a combination of resistance and both capacitive and inductive reactancewhich combines properties of the driver, its mechanical motion, the effects of crossover components if any are in the signal path between amplifier and driverand the effects of air loading on the driver as modified by the enclosure and its environment.
Most amplifiers' output specifications are given at a specific power into an ideal resistive load; however, a loudspeaker does not have a constant impedance across its frequency range.

Instead, the voice coil is inductive, the driver has mechanical resonances, the enclosure changes the driver's electrical and mechanical characteristics, and a passive crossover between the drivers and the amplifier contributes its own variations.
The result is a load impedance that varies widely with frequency, and usually a varying phase relationship between voltage and current as well, also changing with frequency. Some amplifiers can cope with the variation better than egyéb paraziták az időbeli bambuszrostból can.
To make sound, a loudspeaker is driven by modulated electric current produced by an amplifier that passes through a "speaker coil" which then through inductance creates a magnetic field around the coil, creating a magnetic field.
The electric current variations that pass through the speaker are thus converted to a varying magnetic field, whose interaction with the driver's magnetic field moves the speaker diaphragm, which thus forces the driver to produce air motion that is similar to the original signal from the amplifier.
Electromechanical measurements[ edit ] Examples of typical measurements are: amplitude and phase characteristics vs.

Wow! That’s a long title. So here’s the final build of what’s required to build a USB-OTG or OTG-USB cable. Basically a little cable that let’s you use a USB keyboard, mouse, thumb drive, etc. with your phone or to plug USB devices into a Chromecast. This means ethernet connection to your Chromecast.
- Micro USB cable (the kind you charge an Android phone with)
- USB extension cable
Making the Cable:
To make the cable is really easy.
*In case you’re wondering, that’s this end —->
2. You need to cut open the Micro USB end of the Android charging cable. It has to be right at the plug, as the pin we’re trying to get to, doesn’t continue down the length of the cable. It’s actually disconnected.
You can see in this one, if you click on the thumbnail, just above the white cable is the extra pin we want to get at. It’s not connected at the moment. The fact that this is “floating” means that when you connect something to this cable, it will just behave like a normal USB cable. It can charge your device or whatever, but your phone etc. doesn’t know that it has to look for something on the end and load up some drivers etc. for it.
3. Now solder the extra pin we found from step 2 to the ground pin. That means the black cable. Trying o create a jumper from one pin to the other can be difficult when working with small components, so I opted for soldering a small wire to the spare pin, then linking it to the black wire further down.
4. Finally solder the USB female end and the Micro USB end you just patched together. It’s fairly straight forward. Red to red, black to black, white to white, green to green. The spare shielding mesh is worth soldering together on both ends too. Cover it all up with some electrical tape so it doesn’t short between wires and you’re ready to go. You should now see a cable like the following:
This is the simplest cable you can make like this and will allow you to host just 1 device on your phone. If you plug a usb hub into this, you might be able to do 2 or 3 devices (like a keyboard, mouse, and usb flash drive) but your options will be pretty limited unless you get some extra power into the circuit. You can do this by using a powered USB hub, or soldering another normal Male USB connector.
The extra Male USB cable in this case can be plugged into a usb to wall socket adaptor. You just solder in the red and black wires to the other red and black wires in this case. No need to connect the data lines as you won’t be using them.
This last bit is required if you want to use your cable to connect your Chromecast over ethernet. The final part required is simply a USB to ethernet adaptor. Most types will work fine, but here’s a post with a list of ones known to work with USB-OTG.
When you plug it all together with an ethernet cable and Chromecast, just be sure to plug the micro USB into the Chromecast last and it’ll work just fine. You’ll see the extra Chromecast interface and MAC address show up on your router.
As you can see above, I own 2 Chromecasts and one of them now has the second interface showing up.

New Bike Tech on Display at 2013 Tour de France
Pioneer’s Power Meter
1 / 12
A relatively new entry to power measurement, electronics giant Pioneer first showed its unique entry at last year’s Eurobike show. The unit is not as sleek as models from SRM and Quarq, but it can measure left/right power directly, providing an even finer gradation of data than most power meters. The head unit even has a real-time power balance readout. Downside: Currently it works with only Shimano Dura-Ace 7900 and 9000 series cranks. Belkin has been testing the units since last March’s Paris-Nice, but there are no announced plans yet for sale to consumers.

About the book:
The need for time and attention given by the doctor to the patient, due to the increased volume of medical data to be interpreted and filtered for diagnostic and therapeutic purposes has encouraged the development of the option to support, constructively and effectively, deep learning models for applications in the interpretation of medical images. Imaging physicians combine data from different stages and medical experiences, as opposed to DL models that incorporate the same types and modes of artisanal features. The major contribution of this book is primarily to highlight the impact of data quality, type and volume used by deep learning models in medical image analysis accompanied by updated characterization of the components of the deep learning process from data to medical applications. Second, it describes the specific correlations between the components of the deep learning process. Finally, it presents problems and directions for future research.

SANTA CLARA, Calif. -- The current and ongoing downturn has taken a major toll on the semiconductor industry.
But one of the few exceptions to the rule is the semiconductor intellectual-property (IP) business--at least on some fronts. The memory interface IP sector, especially for DRAM, is heating up.
ARM, Denali, Synopsys, Virage and other memory interface IP vendors are now seeing an upswing in business, analysts said. The severe downturn is causing a growing number of OEMs to evaluate or rationalize their internal IP efforts, said Mark Gogolewski, chief technology officer of IP provider Denali Software Inc. (Sunnyvale, Calif.).
The cost of IP development is becoming expensive for OEMs. ''The investments for DRAM interface development have gone up,'' Gogolewski said.
Many OEMs, which never outsourced their chip IP projects in the past, are changing their tunes and mulling over plans to work with the third-party IP vendors, he said.
Denali itself is seeing a sudden swing towards the IP outsourcing trend, especially in the DRAM interface sector. IP outsourcing, coupled by a slight improvement in the economy, is having a positive impact for Denali.
''In Q4, the industry was sitting on its hands,'' Gogolewski told EE Times at the MemCon technology event here. ''Q1 was solid. Q2 is not done yet, but it could be a historical high'' for the IP firm. Denali is a privately-held company. ARM Holdings plc and Synopsys do not break out their IP numbers.
But demand is picking up in IP. In April, IP vendor Virage Logic Corp. said revenue for the second quarter of fiscal 2009 was $11.0 million, compared with $11.3 million for the first quarter and $14.7 million for the second quarter of fiscal 2008. License revenue for the second quarter of fiscal 2009 was $9.1 million, compared with $8.5 million for the prior quarter and $12.1 million for the same period a year ago. For the third quarter fiscal 2009, Virage is projecting revenues of $11.5 million to $12.5 million.
Meanwhile, Denali, one of the DDR-PHY Interface (DFI) specification participating members, also released the official DFI specification version 2.1. The DDR PHY Interface (DFI) specification defines an interface protocol between memory controller logic and PHY interfaces, with a goal of reducing integration costs while enabling performance and data throughput efficiency.
The collaborative technical working group for DFI includes members from ARM, Denali, Intel, LSI, Samsung, and STMicroelectronics.


Just cause I wanted to, and also if it work, it may power future projects that I might fancy, I decided to design up a Power Supply Unit which supplies the 2 most common digital logic voltage levels using either 2 rechargeable or single use AAA batteries.
With a single non rechargeable AAA battery measuring in at 1.5v and a rechargeable AAA 1.25v, 2 of them in series would give me a max 3v. To get it up to 5v, I started looking for a Boost Converter.
I eventually settled on the MAX1674 SMPS, mainly because it was cheap and had fairly good efficiency at higher load levels.
I then stepped the 5v down to 3.3 using the RT9198/A linear regulator.
Throw in an LED to indicate that everything is running smoothly and walah~! Behold the design!!
The board is 26mm x 16mm
All that’s left now is to actually build it and test it…


Through CFD flow simulations, Actiflow studied the airflow inside a centrifugal fan. Based on the simulation results, potential product improvements could be identified. In consultation with the customer, several design suggestions were worked out, and analysed again through simulations. This way, the effect of the suggested design modifications could be analysed without building any prototype. By analysing the full performance curve, also the off design performance could be determined. Based on the insights from all simulations, Actiflow determined the final fan design together with the customer.
Thanks to the CFD simulations, the prototyping costs could be largely reduced and experimental testing could be performed with greater efficiency.


Hyundai and KIA work on a next-gen solar roof for vehicles
Powerful enough to power the EV batteries.
Solar energy is a piece of candy for automakers producing electric cars. However, today there is no existing technology that is capable of making a tangible impact.
Korean Hyundai and KIA are reportedly working to change the situation - companies promise that their next-gen solar panels will generate enough energy even to add some range for electric vehicles. Additionally, they are expected to be transparent, creating a panoramic roof.
Automakers also add that the next-gen solar roof will be developed in three versions - for hyrids, ICE cars and electric vehicles. The technology seem to enter market as soon as next year.

If this is your first time to enter the world of vape, you might be lost in its labyrinth of types and styles of available devices. Not just that, you might feel overwhelmed as well with the terms that are being used here. The goal of this article is to make it easier for you to understand the different components of vape and its types. This is going to help you come up with the best decision of which vape device to get.
Basically, there are basic parts of a vape and while they may have a different look and design, they all do the same function.
Number 1. Vape tanks – simply speaking, this is the part of vape that is housing the e-liquid, the heating coil and the wicks.
Number 2. Vape coils – this is either an assembly of wire or a replicable section in a spring like coil shape that is wounded. As for the coils, they are wicked using any absorbent material which is most of the time cotton to be able to absorb the juice. Then after, wire coils are heated until it vaporizes the juice that’s put on wicks.
Number 3. Batteries – this technically powers the mod or the device and you will quickly observe that some of the vape devices have integrated batteries while others are using replaceable cells.
Number 4. Vape mods – the job of this specific component is to provide a housing to battery that will connect and transfer the power to atomizer/clearomizer.
Number 5. E-juice – this is heated up to create the vapor which is made using combination of ingredients such as vegetable glycerin, propylene glycol, food flavorings.
After learning the different components of a vape device, let us now talk about its different types.
Pen style – compared to cig-a-likes, these devices are just a little bit bigger and it’s to make room for bigger battery. The great thing about these devices is that, they are easy to use and budget friendly.
Mechanical mods – these actually have minimalist design so it is hard to see circuitry or wires on its construction and there are a number of moving parts that may go bad or wear out. But don’t worry because these devices are very durable and can take abuse. If you want to push your vaping experience to the limit, then this is what you are looking for.
Cig-a-like – this is the most used vape device in the market and typically fall in one of two types which is either refillable or disposable. Both types function the same way with an exception that the latter is thrown away when the liquid runs dry or the battery dies.
