Air Flow and Mass Sensing Devices
Air Flow and Mass Sensing Devices:
A Mass Air Flow/Air Flow Meter/Speed Density Primer
When one reads about mass air flow sensor contamination, it is important to recognize that a modern engine can use one of five distinct categories of air measuring devices, each of which works on very different physics principles. In order to assist your understanding of the various strategies used on fuel injection-equipped engines to measure and calculate air flow or mass, we've assembled the following primer.
In order to precipitate combustion, internal-combustion engines need air, fuel and spark. Before the advent of fuel injection, carburetors were used to distribute an appropriate amount of fuel for a given amount of air. Carburetors function on Bernoulli's principle: Air pressure drops as airflow increases, and the resulting vacuum is used, in conjunction with mechanical bits, to meter a proper fuel mixture.
In the 1980s, fuel injection became the standard in automotive engines as a more precise method of meeting fuel needs for a given airflow, paying dividends in efficiency and thus performance, fuel economy, and emissions. Modern electronic fuel injection systems feed pressurized fuel to computer-controlled, solenoid-type injectors which deliver accurate quantities of fuel into the engine's intake system or combustion chamber.
Engine sensors and inputs, in conjunction with an engine computer (ECU or Engine Control Unit), measure airflow and mass in order to calculate the proper amount of fuel so as to as closely approach the stoichiometric, or chemically correct, ratio of air mass to fuel mass for fuel to be burned completely: 14.64:1. These inputs can include an exhaust gas oxygen sensor (O2 sensor), wideband 02 sensor or "lambda" sensor, air flow or air mass sensor, intake air temperature sensor, manifold air temperature (MAT) sensor, manifold absolute pressure (MAP) sensor, throttle body position (TPI) sensor and engine revolutions per minute (RPM).
Vane Air Flow Meter
The Vane Air Flow Meter (VAFM), was one of the first airflow sensors in use and has been largely phased out of new car production. In a vane, or as it's commonly called, "flapper-style" air flow meter, intake air flow exerts force against the surface area of a measuring plate, which is deflected in proportion to the volume of air flow meeting the plate. Movement of the measuring plate is transferred through a shaft to a slider on a potentiometer resistor, which produces a variable voltage signal proportional to the air intake volume. Once air volume, expressed as force exerted over a surface area, is measured, air mass is calculated in conjunction with an air temperature sensor.
Another mechanical-type AFM is the plunger type, which uses a sliding sprung cone-shaped plunger, rather than flap, to measure airflow, deduced from its position on a calibrated scale. Due to the mechanical nature of measurement, vane and plunger type meters are largely impervious to the effects of contaminants, but less accurate than other AFM/MAF types.
Karman Vortex Air Flow Meter
An older style of AFM still in limited use, the Karman Vortex air flow meter uses an air stream-centered conical vortex generator to create vortices, essentially precisely-shaped air disturbances, in the measurement chamber. First, however, the air stream passes through a honeycomb grid to straighten airflow and reduce turbulence.
Located on either side of the chamber of one type of vortex meter are a transmitter and receiver that send and receive a signal, either infrared light or ultrasonic waves. The amount of distortion in signal caused by the vortices, whose frequency increases with airflow, is measured and compared against a known set data points, from which an inference about air flow is made.
Another type of Karman Vortex Meter features a pressured directing hole in which sits a metal foil mirror which oscillates in proportion to the vortex frequency. The movement of the mirror deflects light from an LED on and off of a photo transistor or diode, opening and closing a 5-volt loop to generate a signal. Air flow, combined with a temperature reading from an internal sensor, is used to generate a measurement of air mass.
Speed Density systems do away completely with a mass air or flow device, instead marrying inputs like RPM, throttle position (TPS), manifold absolute pressure (MAP), which compensates for altitude, and incoming air temperature to calculate air mass. Various aftermarket products exist to convert MAF-equipped cars to speed density, which are traditionally used in forced induction applications with high airflow numbers.
Unlike air flow meters, hot wire or hot film mass air flow sensors directly measure air mass, as the convective qualities of air are affected by factors like temperature, humidity and density. Hot wire sensors create an analog signal and hot film sensors a digital frequency signal.
Most common hot-wire MAF sensors use a platinum wire or filament heated to a prescribed, maintained temperature above ambient, located centrally in the incoming air stream. These sensors function on the electrical principle that resistance increases with temperature. As intake air moves past the wire or film, the cooling effect causes a measurable drop in resistance, and thus lower voltage is required to maintain the prescribed temperature. The hot-wire MAF control unit is sent a reference voltage of 5V, and returns around .4V to.5V at idle and from 4.5V to 5V at full throttle. Based on a fixed data set, an accurate assumption of air mass is made.
Readings can stray from the target values as a result of contamination of the wire and for the sake of accuracy, an additional input from an integrated intake temperature sensor is sometimes used. Many hot wire MAFs incorporate a burn off cycle when the ignition is switched off, heating the element to over 1800-degrees F to clear it of contamination. Hot wire sensors are the most physically delicate and easily contaminated of all the air flow and mass sensors.
Hot-film MAF sensors function much like a hot wire sensor, and used a centrally-heated film or metallic grid-type element. One side of the film encounters cooling airflow, while the shielded backside maintains a consistent temperature, and the current differential between the two is measured and relayed as a square-wave digital frequency output, between around 30Hz at idle and 150Hz at wide-open throttle. Hot film sensors tend to be more robust and less susceptible to contamination than hot-wire types.
Mass Air Flow Sensor Contamination:
Contamination of hot-wire type sensors does occur. Usual suspects include substances like silicone potting compound, dirt, oil and spider webs.
Potting compound, used in the manufacture of the sensors to environmentally seal them can migrate onto the wire.
Oil most often enters a MAF in the form of vapor via an engine's PCV system. In an effort to lower emissions, positive crankcase ventilation systems use a PCV valve to draw fuel and oil vapors from the crankcase, this can allow blow-by gases to make it past the piston rings, and reintroduces them into the intake system upstream of air flow metering devices. When a throttle body or airflow meter needs cleaning, the oily film that is removed is largely a product of this system.


With 5G phones in the low-to-midrange price segments becoming more and more common, OPPO recently decided to release the 5G variant of the A74 globally, including the Philippines.
Locally, the latest ！ and fastest ！ network standard is available in many parts of the country¨s capital region, so getting a 5G phone like the OPPO A74 5G now will allow you to take advantage of faster networks as they roll out in your area.
Of course, that¨s not the only advantage the A74 5G model has over the vanilla model. It sports a slightly bigger display with a higher, 90Hz refresh rate, albeit at the cost of AMOLED. It also adds a dedicated ultra-wide camera at the back for landscapes and group pictures, plus a more powerful chipset in the Qualcomm Snapdragon 480 5G.
Priced at P15,999 (roughly $336 converted) in the Philippines, is the brand¨s most affordable 5G phone in the country a worthy upgrade? Read our full review of the OPPO A74 5G to find out.
The OPPO A74 5G sports a plastic body with a glossy finish in solid silver or gradient black or gray-ish, which OPPO calls Fluid Black. The Space Silver variant features a less flashy design, but both color options look good in pictures and in person. Neither comes across as too loud to look at. If given a choice, we¨d pick the black A74 5G that we used for this review because it¨s a little more eye-catching yet still subdued enough with its selection of hues.
Our OPPO A74 5G in Fluid Black review unit is eye-catching yet still subdued enough with its selection of hues
The phone¨s width is just right for one-handed use, but its extended display makes reaching the top of it a bit uncomfortable. The extra weight and thickness of the unit are not particularly surprising and justified to accommodate the 5,000mAh battery, plus additional antennas for 5G coverage.
In typical OPPO fashion, the right-hand side of the device houses the power/key button, whereas the volume keys and hybrid-card tray are located along the left edge. The former gets an embedded fingerprint reader, as usual, to help you avoid the hassle of manually keying in your password. It¨s fast and reliable, and it¨s exactly where it needs to be if you¨re right-handed, not too far up or down the right side of the smartphone.

As for the card tray, it can accommodate two nano SIMs and one microSD card simultaneously, giving you the option to use two mobile numbers at the same time and switch between 5G networks depending on which operator offers better service in your area.
Up top, the handset is bare, not even a second microphone for noise cancelling during calls. All the ports ！ a USB-C port for charging and file transfer and a 3.5mm headphone jack for legacy audio devices ！ as well as the single loudspeaker can be found at the bottom.
There¨s a punch-hole cutout on the upper-left side of the display for the selfie camera
Moving to the front, the OPPO A74 5G packs a 6.5-inch LTPS or low-temperature polysilicon LCD screen that, compared to traditional LCDs, helps lower power consumption and results in a higher pixel density, and therefore a sharper image. Like many other OPPO phones, there¨s a punch-hole cutout on the upper left for the selfie camera.
The panel has a resolution of 2,400 x 1,080 with a wide aspect ratio of 20:9. It can get pretty bright, too, offering up to 480 nits of peak brightness in Auto mode, so you can use it outdoors without needing to squint at the screen.
And it does look good when in use, capable of pleasing detail, accurate colors, and wide viewing angles one would usually associate with LCD panels at this price range. However, we don¨t think it¨s the best choice for value, especially if you¨re after the vibrancy and deep black levels of an AMOLED display.
The A74 5G¨s 90Hz refresh rate makes OPPO¨s latest Android 11-based ColorOS 11 user interface, in particular, look more fluid
Perhaps the best spec here is the A74 5G¨s 90Hz refresh rate, which isn¨t standard fare for most OPPO devices even in 2021. This makes OPPO¨s latest Android 11-based ColorOS 11 user interface, in particular, look more fluid, especially when scrolling up and down the screen. When playing games, don¨t expect the same smoothness all the time, as the display seems to max out at 60Hz due to the limitations on the chipset. Out of all the games we tried, only Dead Cells and Alto¨s Adventure ran at a frame rate higher than 60 fps.
Still, even with its utility limited to the UI, using a 90Hz screen feels way nicer than a 60Hz one. And we can¨t really fault OPPO for the Snapdragon 480 5G¨s gaming performance, which falls in line with the Snapdragon 720G and most midrange chipsets on the local market.
The OPPO A74 5G adopts a quad-camera setup with a 48-megapixel, f/1.7 camera alongside an 8-megapixel ultra-wide shooter and 2-megapixel macro and depth sensors in a rectangular module. The lone selfie shooter has 16 megapixels. Minus the wide-angle option, those specs are virtually identical to those of the A74 version that doesn¨t have a 5G chipset.
The OPPO A74 5G features a 48-megapixel quad-camera setup
In the daytime, pictures turn out bright, detailed, and sharp, while Auto HDR helps balance scenes, taking care of shots that are in danger of over- or underexposure. The camera package here is decent for low light, too, with the option to take brighter images in Night mode, which is available on the main, ultra-wide, and front-facing cameras.
You can¨t save RAW files in Expert or manual mode, which would work great in post processing. But you do get a helpful pop-up screen to explain what each camera setting does and how to approach a specific scene.
Elsewhere, the 16-megapixel front-facing camera is a capable shooter that delivers plenty of detail and sharpness, in addition to accurate skin tones. It also captures nice self-portraits with good edge detection in daylight that will survive close inspection. Most of the included filters look nice, too, but the software extras here pale in comparison to what competing phones offer.

And one more´
The OPPO A74 5G supports video recording at up to 1080p at 30 frames per second with its rear and front cameras and up to 720p at 30 fps with its ultra-wide option. While not being able to shoot in super-sharp 4K is completely understandable, our biggest gripe is the lack of 60 fps shooting.
The OPPO A74 5G runs the latest Qualcomm Snapdragon 480 5G SoC and is the first device to do so in the Philippines. We¨re pretty excited with this particular chip, in large part because it¨s the cheapest Qualcomm silicon with a 5G modem. Besides 5G, it also introduces the 4 series to the 8-nanometer process, allowing for remarkable efficiency when handling serious workloads.
It uses an integrated Qualcomm Snapdragon X51 5G, which supports multiple 5G spectrums, modes, and frequencies at lightning-fast peak download and upload speeds of 2.5Gbps and 660Mbps, respectively. Both mmWave and Sub-6 GHz spectrums are supported, as well as SA and NSA modes.
Our review unit can connect to 5G networks in the Philippines without any problems, and the results we saw using the Ookla Speedtest app and Netflix¨s Fast were comparable to other similarly priced 5G phones we¨ve tested in recent months. As far as speed and coverage are concerned, there¨s really nothing to complain about with the OPPO A74 5G.
5G speed tests on the OPPO A74 5G
The Snapdragon 480 5G mixes two performance Kryo 460 cores clocked at 2GHz with six 1.8GHz ones for less demanding tasks. The Kryo 460 cores are semi-custom Cortex-A76 CPU designs supplied only to Qualcomm. For graphics work, the Snapdragon 480 packs an Adreno 619 GPU, which is also included in the Snapdragon 750G 5G that has faster Cortex-A77 CPU cores.
The benchmark scores are quite impressive, especially considering where the Snapdragon 480 5G ranks in the bigger scheme of things. The results we got were not of a typical 4 series chipset, but given the specs, these numbers are expected.
Performance-wise, the Qualcomm Snapdragon 480 5G is similar to the 4G-only Snapdragon 720G, though that is a credit to the former more than a knock on the latter. In going toe to toe with one of Qualcomm¨s most popular midrange SoCs, the Snapdragon 480 5G has shown that it can punch above its weight.
But is it a better all-around choice than the equally low-end (among 5G chips, at least) MediaTek Dimensity 700 5G? Not really, especially if you don¨t care much about thermal throttling; so far, the Snapdragon 480 5G seems largely unaffected by it.
Gameplay: Genshin Impact, Mobile Legends: Bang Bang (3:01 mark), Dead Cells (6:01 mark), and Alto¨s Adventure (9:01 mark)
The A74 5G can play Mobile Legends at a smooth 60 fps with the settings at High. Dead Cells runs at above 60 fps with the frame-rate option unlocked. We were able to maintain close to 40 fps in Genshin Impact with the settings set to Low. And Alto¨s Adventure, easily the least demanding game we played on the handset, achieved frame rates as high as 89 fps, essentially maxing out the smartphone¨s 90Hz panel.
Our CPU Throttling Test results revealed the OPPO A74 5G dropping to 86% of its max performance at most. There was no throttling detected on the device after five minutes of stress-testing, while its performance dropped to 89% at the end of a 60-minute test.
Those are impressive numbers, to say the least, and it¨s important to note that the Snapdragon 480 5G¨s 8nm process no doubt plays a significant role in allowing the chipset to perform at peak capacity for longer periods. Given the efficient internals, heat isn¨t a problem here. We didn¨t encounter any issues, even when gaming for long stretches at a time.

CPU Throttling Test results
The new ColorOS 11 includes the improved Game Space app, which comes into play if you¨re the type of gamer who easily gets distracted by alerts and notifications, or if you simply want to get the most out of the phone¨s internal hardware by giving you the ability to switch between Pro Gamer, Balanced, and Low power modes on the fly, for instance.
As far as battery life is concerned, the OPPO A74 5G provides a day or two of mixed use. The 5,000mAh cell should provide a lot more mileage if your typical usage doesn¨t involve 5G data and gaming for long periods.
Synthetic benchmarks can be good predictors of real-world performance. Unfortunately, our non-retail unit couldn¨t complete a PCMark battery-test run. In our video-loop test, though, the handset played a 1080p YouTube video on loop and lasted 7 hours and 30 minutes from half capacity. The A74 5G ships with an 18-watt charger and requires about 2 hours and 30 minutes plugged in to reach full charge from zero.
The OPPO A74 5G scores huge wins in the chipset department, capable of blazing-fast downloads in 5G areas and consistently smooth gameplay coupled with solid battery life. The cameras at the back and on the front did good as well in our tests. While the display isn¨t as vivid as others at this price level, it produces nice colors and is bright enough for most scenarios.
OPPO¨s most affordable 5G phone isn¨t the cheapest on the local market, but it¨s certainly still a good one. After spending several weeks with the A74 5G, we were smitten with its efficient performance and fluid display. If you or someone you know is on the lookout for an accessible entry-point for the latest and fastest wireless standard in the P15,000 ($314) neighborhood, this is a great deal.

Bekenstein's topical overview "A Tale of Two Entropies" describes potentially profound implications of Wheeler's trend, in part by noting a previously unexpected connection between the world of information theory and classical physics. This connection was first described shortly after the seminal 1948 papers of American applied mathematician Claude E. Shannon introduced today's most widely used measure of information content, now known as Shannon entropy. As an objective measure of the quantity of information, Shannon entropy has been enormously useful, as the design of all modern communications and data storage devices, from cellular phones to modems to hard disk drives and DVDs, rely on Shannon entropy.
In thermodynamics (the branch of physics dealing with heat), entropy is popularly described as a measure of the "disorder" in a physical system of matter and energy. In 1877 Austrian physicist Ludwig Boltzmann described it more precisely in terms of the number of distinct microscopic states that the particles composing a macroscopic "chunk" of matter could be in while still looking
like the same macroscopic "chunk". As an example, for the air in a
room, its thermodynamic entropy would equal the logarithm of the count
of all the ways that the individual gas molecules could be distributed
in the room, and all the ways they could be moving. wiki

“India Times: India is installing along its long coastline a sophisticated surveillance system capable of tracking movements as distant as 20 kms in the sea with a command and control centre in Delhi from where the entire coast can be monitored, officials said here. Civil works to put in place the system, comprising a radar, electro-optic sensor and command and control software are underway.
With the system, “we can monitor any square inch of the entire sea of the country and see visually,” said I V Sarma, Director (R&D) of Bangalore-headquartered BEL, a defence electronics company, which developed the system for the Coast Guard .
In the first phase, these surveillance stations would come up in 46 sensitive coastal locations by next year-end. The idea is to start the deployment with the west coast, sources at Bharat Electronics Limited (BEL) said.
“Trials (for testing the system) are over and a formal contract will be signed with the government before December end,” Sarma, adding “we will start putting equipment from January onwards”.
Though contract negotiations have not been completed, BEL expects the first phase order to be worth Rs 500 crore to Rs 600 crore.
“We hope to install and commission the system (first phase in 46 locations) in the next 10 months to one year (from January next year),” he said.
While surveillance stations are being put up in sensitive areas in the first phase, the subsequent second and third phase to be taken up would address the ‘gaps’ to ensure that the entire coastal region is covered.
Sarma said cameras in the coastal surveillance system operate during day and night as well in low-light conditions. BEL has been working on this project for about an year.
“The set-up cameras is used for a range of 20 km. Both radars and camera are capable of going up to a distance of 20 kms into the sea,” he said.”


D3 is a turnkey unmanned aerial system (UAS). It consists of fully autonomous and highly modular electric glider, integrated autopilot, and ground control software. D3 is ready to fly out-of-the box with minimal training similar to the widely spread consumer multirotor drones.
The main D3 advantage is flight time up to 3 hours with an off-the-shelf 10Ah LiPo battery. In other words, six times longer than a typical multicopter flight of 30 minutes. Additionally, the D3 can take advantage of any local thermals and maintain or even gain altitude without the help of its electric motor. Therefore, the D3 can scan more area and cover longer distance than any multicopter while maintaining a cruise speed of 55km/h.

“The history of programming languages spans from documentation of early mechanical computers to modern tools for software development. Early programming languages were highly specialized, relying on mathematical notation and similarly obscure syntax. Throughout the 20th century, research in compiler theory led to the creation of high-level programming languages, which use a more accessible syntax to communicate instructions. The first high-level programming language was Plankalkül, created by Konrad Zuse between 1942 and 1945. … The period from the late 1960s to the late 1970s brought a major flowering of programming languages. Most of the major language paradigms now in use were invented in this period: Speakeasy, developed in 1964 at Argonne National Laboratory (ANL) by Stanley Cohen, is an OOPS (object-oriented programming system, much like the later MATLAB, IDL and Mathematica) numerical package. … Simula, invented in the late 1960s by Nygaard and Dahl as a superset of Algol 60, was the first language designed to support object-oriented programming. FORTH, the earliest concatenative programming language was designed by Charles Moore in 1969 as a personal development system while at the National Radio Astronomy Observatory. C, an early systems programming language, was developed by Dennis Ritchie and Ken Thompson at Bell Labs between 1969 and 1973. Smalltalk (mid-1970s) provided a complete ground-up design of an object-oriented language. Prolog, designed in 1972 by Colmerauer, Roussel, and Kowalski, was the first logic programming language. ML built a polymorphic type system (invented by Robin Milner in 1973) on top of Lisp, pioneering statically-typed functional programming languages. Each of these languages spawned an entire family of descendants, and most modern languages count at least one of them in their ancestry. …”

Gaston Ormazabal is a Senior Research Scientist at Columbia University in the Department of Computer Science where he is co-leading a major research initiative on next generation wireless internet technologies (5G) that is funded by major technology-industry corporations. He previously worked at Verizon Laboratories for twenty seven years as a Distinguished Member of the Technical Staff. He holds a B.A from Harvard University, and M.A., M. Phil., and Ph.D. degrees from Columbia University, all in Physics. While at Columbia, as a graduate student, he conducted research in particle physics at Fermi and Brookhaven National Accelerator Laboratories. After graduation, he went to work at Bell Communications Research (Bellcore) developing packet switching technology. From Bellcore, he went, as one of the founding members, to NYNEX Science and Technology (today Verizon Labs) where he worked in projects ranging from speech recognition, video compression, data warehousing and data mining, to Fast Packet, SONET and IP technologies. He also developed a predictive analysis expert systems tool using performance-monitoring data to predict a circuit failure using a modified Markov Model. Most recently, he was responsible for Network Security Systems Integration and Testing, concentrating in areas of VoIP and Video Security Protocols and Management Systems, as well as involved in designing a Security Management Infrastructure for the Next Generation Network (NGN). Concurrently, Dr Ormazabal conceived a research project on VoIP Security at Columbia University Internet Real-Time Laboratory in the Department of Computer Science in which a high scalability SIP-aware Application Layer Gateway was developed using a highly distributed hardware platform, along with the testing environment to verify its performance at carrier-class traffic rates; the latter based on his patented design and methodology (US Patents 7,076,393, 7,421,734). The project was expanded to develop a SIP-based distributed denial-of-service detection and mitigation system, the first of its kind. This research was conducted under the co-direction of Department of Computer Science Chairman, Professor Henning Schulzrinne. The results were presented at NANOG-38, Global 3G Evolution Forum in Tokyo, Japan, IPTComm 2007 in New York City and IPTComm 2008 in Heidelberg, Germany. Dr Ormazabal was also an invited guest at the “Third International IMS Workshop” at the prestigious Fraunhofer-FOKUS research institute in Berlin, the first FBI-sponsored International Conference on Cyber Security (ICCS) 2009 in New York, the IEEE CQR 2009 (Naples) and 2010 (Vancouver) Conferences and the Illinois Institute of Technology VoIP Conference and Expo (Chicago) where he has been either key-note speaker or Security section Chair, annually since 2008. The project generated nine joint Columbia-Verizon patent applications. This breakthrough security technology has spawned a quadripartite industry-academic collaboration under Dr Ormazabal’s leadership, involving the Center for Advanced Technology Telecommunications (CATT) at New York University, Columbia University, Verizon and Cisco to research the optimal hardware platform for an eventual commercialization. This collaboration has received worldwide press coverage. As a former particle physicist, Dr Ormazabal was also recently involved in investigating cosmic rays as the source of single event upsets (SEU) in router memory chips and provided briefings to Department of Homeland Security national infrastructure protection officials.

On a personal level, Gaston is a dual citizen of the United States and Chile, resides in New York City, and has had a life-long passion for classical music and opera. Significantly, he had a long and very close association with the great German Dramatic Soprano, Hildegard Behrens, most famous for her dramatic portrayals of the great Wagnerian and Straussian heroines. He was her close musical and artistic advisor. This friendship afforded him front row seats to some of the most significant musical events between 1980 and 2005, in New York (Metropolitan Opera, NY Philharmonic and Carnegie Hall), Boston (Boston Symphony Orchestra), San Francisco (San Francisco Opera), London (Royal Opera House at Covent Garden), Munich (Bavarian State Opera), Berlin (Deutsche Oper), Vienna (Vienna State Opera), Athens (Herodes Atticus and Megaron), Buenos Aires (Teatro Colon) and the Bayreuth and Salzburg Festivals. He has been an enthusiastic supporter of young musical talent and the mission of YOA Orchestra of the Americas since hearing the Orchestra’s 2006 Munich performance of Verdi’s Messa da Requiem conducted by Plácido Domingo. In March of 2010 he became a Member of the Board of the YOA. On August 18th 2010, he created The Hildegard Behrens Foundation, as Founder and Chairman, to memorialize the achievements of the great German soprano, by promoting and giving scholarships to young musicians that aspire to the deeply held humanistic ideals espoused by the soprano during her memorable lifetime.


Matter Labs has launched a testnet for the second iteration of its zkSync scaling solution, which has taken another step towards solving the Ethereum blockchain trilemma.
In a June 1 announcement, Matter Labs revealed that the alpha version of zkEVM testnet had gone live. The platform provides full Ethereum Virtual Machine compatible smart contract deployment in a Layer 2 environment.
zkSync speeds up Layer 1 Ethereum transactions by using zero knowledge rollups to batch transactions and process them off the root chain. It can also provide security guarantees comparable to a normal smart contract on Layer 1.
Solving the trilemma
zkSync 2.0 and its zero-knowledge EVM testnet aims to make progress with the scaling blockchain trilemma of security, scalability, and decentralization. Traditionally, one has to be sacrificed in order to improve the others.
“All current scaling solutions reside on a spectrum of sacrificing some security, decentralization, and programmability for scalability.”
Matter Labs stated that when developing on Ethereum, there is a fourth element to the equation, which is programmability. The design of zkSync 2.0 maximizes all four features with the two technological breakthroughs, it added.
The zkEVM engine will power the zkRollup, which is the current solution for maintaining Layer 1 security and solidity smart contract support. An additional protocol called zkPorter, which was unveiled in April will provide an off-chain data availability system to turbocharge the existing rollups.
Ethereum co-founder Vitalik Buterin spoke about the importance of the scaling trilemma in a recent blog post responding to fundamentally flawed comments Elon Musk made about Dogecoin’s superiority.
Endgame in Ethereum scaling
The two are interoperable and composable, enabling zkSync 2.0 to significantly outperform all other scaling solutions, it added. When sharding is launched with ETH 2.0 next year it will provide an exponentially larger data availability layer without sacrificing decentralization.
“zkSync’s zkRollup technology combined with Eth2 data sharding is the endgame, hitting 100,000+ TPS without sacrifices on any of the 4 factors.”
It used Uniswap as an example explaining that the DEX can be deployed on the zkRollup side to swap for the lowest fees by zkPorter accounts.
Matter Labs added that once the testnet is complete, it will focus on making its Zinc programming language more expressive and feature-rich. Following that it will build the Rust programming language compiler frontend to allow smart contract coding using native Rust.
In late March, the Asian decentralized crypto wallet provider imToken announced a partnership with Matter Labs to develop scaling solutions.

The 10ZiG 5910q Win 10 IoT Thin Client, qualified for HDX Ready, HDX Premium and HDX 3D Pro verification levels, is the first Citrix Ready verified endpoint to support the new H.265 video decoding ability on Citrix Receiver for Windows, setting a new industry standard which will enhance Citrix workspace solutions for its customers using 10ZiG endpoints.
Leicester, UK - July 12, 2018 - 10ZiG Technology today announced that its 5910q Windows 10 IoT Thin Client is verified as Citrix Ready and becomes the first VDI endpoint provider to achieve the new Citrix H.265 encoding support.
Not long after the Citrix release of H.265 High Efficiency Video Coding (HEVC) Technology, 10ZiG was quick to respond and support the revolutionary codec via its exceptional triple-monitor, 4K UHD, power class 5910q Windows 10 IoT Thin Client. Once HEVC was announced for Citrix XenDesktop7.16 and NVIDIA GPUs, 10ZiG left slower-moving endpoint providers behind by quickly becoming the first to achieve Citrix Ready for the H.265 codec.
Says Kevin Greenway, 10ZiG CTO, “As with any new release feature, 10ZiG is always ready to quickly get our cutting-edge, high-performing, hardware supportive as soon as possible. Our 5910q device for Windows 10 IoT is the perfect fit for H.265 codec support, as it really pushes the boundaries with its high-quality, 4K UHD, triple-monitor advantage. The combination of the exceptional hardware features with Citrix and H.265 HEVC, offers 3D graphics use cases with improved visuals and reduced bandwidth at up to 4K (UHD) resolutions.”
“10ZiG has been a great Citrix Ready program partner for years. Not only has their 5910q Thin Client passed all three levels of Citrix Ready verification, most notable is that this device supports the Citrix H.265 HEVC codec,” said John Panagulias, Director, Citrix Ready, Citrix. “Their responsiveness to adapt so quickly to the latest release feature is impressive, and we appreciate this milestone achievement as it allows Citrix to now deliver an end-to-end VDI solution more powerful and efficient than ever before.”
The 10ZiG 5900q Series Thin and Zero Client product line is one of the newest endpoints on the market today. It is based on the Intel Braswell Refresh CPU platform, which is one of the few that work with H.265 codec. Its 3-monitor support includes a 1x HDMI / 2x DisplayPort combination and other features include Touch Technology, Optional PoE, and more.
The H.265 codec is the new video compression standard improving coding efficiency. H.265 offers an average 20% reduction of bandwidth consumption with amazing display quality. Its algorithm uses efficient coding by encoding video at the lowest possible bit rate, while maintaining the highest image quality level possible. Both H.265 and H.264 compare and replace different parts of redundant video frames with short information describing the original pixels. Where H.265 differs is its ability to expand the size of these areas into smaller or bigger blocks. This range of capability is much greater in H.265. The end result for Citrix & 10ZiG users is better compression, lower bandwidth, and top-quality displays.
Please join 10ZiG & Citrix for a live webinar on July 25th, 2018 at 5pm BST/6PM CEST as they “Explore the Benefits of Citrix H.265 Encoding with the 10ZiG 5910q Thin Client.”

Roku Distant Not Working? This Is How You Can
Pairing is the time period for connecting two Bluetooth enabled units together. If your connection isn’t working, re-pairing is an effective way to attempt to repair the connection. This methodology is only applicable for Samsung good remotes. My hisense 55H9908 distant does every little thing except turn the TV on. We should manually flip the TV on with the button on the TV.
Start by altering the batteries in your distant. If that doesn’t remedy the problem, there could also be damaged to the amount keys or circuitry, so I would recommend buying a brand new remote. Clear the electrical contacts with 150-grit sandpaper.
Use this to navigate to the menu and replace the TV software or firmware to aim to get the distant working. Press the ability button of the distant for three seconds. The remote could not work quickly as a result of poor contact of the battery or static electricity. Make positive not one of the remote buttons are jammed. Make certain the IR sensor on the system is not exposed to direct daylight or bright lights. The following are common troubleshooting seteps that handle many of the issues that may happen with an infrared distant control.
What To Do When The Television Does Not Reply To The Infrared Distant Control?
Usually, it’s paired routinely, but if it hasn’t, you should conduct compelled pairing. Sometimes there may be some problem along with your Samsung TV remote and they’re actually painful, as you merely can’t use all TV’s features with out the remote. A lot of people are just going to purchase a new one, however usually remote issues could be mounted at house. If the TV turns on, the problem is in your Toshiba distant.
Most remote controls (TV, garage doors, and so on.) have conductive rubber on the again of the buttons, making contact with the circuit board contained in the device. Over time, these rubber buttons can wear away and cease working. With a bit of our conductive paint, you’ll be able to repair the buttons and restore your gadget. Make positive to remove any batteries before trying to repair your distant.
Repaint every button with a brand new coat of conductive paint. Let it remedy for 72 hours before reassembling. Remove the buttons from the circuit board and scrub off any sticky stuff with water and dishwashing liquid.
Samsung Television Distant Not Working Issue
First verify whether the problem is because of the TV or the remote management. If the problem is because of the remote control, you will be guided in Section by remote management sort. If the problem still occurs after following the steps above, then the remote management will need to be changed. Perform a power reset of the system.Unplug the gadget. Check to confirm that the remote control sends an infrared sign. A broken distant control must be changed.
Proceed to step 2 to verify the performance of the distant control. If these buttons don’t work, power-cycle your digital receiver and check out once more. You can power-cycle your digital receiver by upluging the ability cord from the back of the receiver, wait 15 seconds, then plug the ability twine back in. If the buttons on the converter still don’t work, please name us for assist.
Generally, it’ll contain pressing two buttons siultaneously for three or more seconds, whereas pointing the remote at your TV. Temporarily turn off any fluorescent lights or overhead lights near the TV. Certain fluorescent lights or LED bulbs can intervene with the remote management sign and cause it to malfunction.


The need for improved network performance and more efficient use of network resources will require fundamental changes in the mobile network architecture. P.I. Works technology is designed to address those requirements and help operators expand the mobile wireless capacity to meet the future demand for mobile communication.
Increasing complexity and densification of mobile networks present a compelling argument for the need for self-aware networks. This will only be possible by moving to a virtualized, software defined network architecture. Operating this new architecture requires a shift in the existing network management and optimization approach, and Artificial Intelligence (AI) will lay the foundation of this new approach. P.I. Works already started incorporating AI capabilities to its solutions. For example, by using the adaptive algorithms that recognize the network traffic patterns and utilization level of existing cells, our smart energy saving solution puts underutilized cell sites into idle mode. A tier 1 European operator already demonstrated approximately 5% reduction in the power consumption in a specific cluster of its live network. This is among the many examples of how P.I. Works is revolutionizing the way mobile networks are managed.
Another important aspect of mobile network evolution is that the networks needs to become more customer aware and SON is instrumental in achieving this. Collecting and correlating CEM (Customer Experience Management), crowdsourced, CRM (Customer Relationship Management), and access network data will give the operators the power to deliver a tailored Quality of Experience to specific customer groups. This will take the customer experience to a whole new level.
Last but not least, as the network becomes a virtual pool of resources and is sliced for specific applications, SON will play an important role in orchestrating the entire network and optimizing specific application layers. P.I. Works approach to mobile network management includes the monitoring of activities in the entire network, and taking actions in the transport and the radio access network together, so that the network performance can be managed more effectively.
If you want to learn more about how P.I. Works can help you in transforming your mobile network by using the power of SON, come and join us at MWC Americas, booth #W713.

BY CHRISTOPHER ESSNER
“One small step for a man, one giant leap for mankind.” Those were the iconic words spoken by Neil Armstrong as he became the first human to step foot on the moon. It marked a new day in the age of humanity; a day of historic scientific achievement; a new age of exploration. The Apollo 11 moon landing was over 40 years ago, and Buzz Aldrin, the second man on the moon, believes it is time humans set their sights on Mars.
In his new book, “Mission to Mars: My vision for Space Exploration” Buzz Aldrin, a native of Glen Ridge, N.J., lays out a plan for NASA to reach the red planet within the next 20 to 25 years. This will not be an easy task however as NASA has been forced to deal with large budget cuts and dwindling public interest regarding human space exploration.
Human lunar landings have been absent since the iconic Apollo program was completed, and the much of NASA’s space exploration projects have included machines, rovers, satellites. Some would like to see NASA astronauts return to the moon before any thoughts of a Martian mission are considered, but Buzz Aldrin believes this would be a mistake.
“Do not put NASA astronauts on the moon. They have other places to go,” Aldrin said in a statement to Fox News.
This is not the first time Aldrin expressed his desire to see NASA astronauts explore our celestial neighbor. In the 1980s Aldrin conceptualized the “Aldrin Mars Cycler,” a spacecraft transportation system cycling between Earth and Mars that would ferry astronauts back and forth.
Exploration is intertwined with human history. Humans have always have the drive, want and need to explore new lands, see new things, and go one step beyond what was previously thought possible.
Astrophysicist Neil deGrasse Tyson believes that a manned Martian mission has the ability to re energize the United States the same way the Apollo missions did in the late 60s and early 70s.
“During the Apollo era you didn’t need government programs trying to convince people that doing science and engineering is good for the country. It was self-evident,” said Tyson. “ Fully funded mission to Mars and anywhere beyond low earth orbit commanded by astronauts who would now be in middle school would reboot America’s capacity to innovate as no other force in society can.”
The future of space exploration may not lie with government funded programs however. As programs like SpaceX continue to grow we may see a greater shift towards the private sector. Millionaire Dennis Tito is planning to launch a Mars mission that would send to people into orbit by 2018, and non-profit organization Mars One is looking to land four people on the planet to begin colonization. The catch to the 2023 plan is that it may be a one way trip.
Whether you believe a Mars mission should be undertaken by NASA or private organizations, one thing is certain. Humans will always have that hunger to go beyond what was once thought possible. As technology continues to advance this undertaking may not seem so impossible.

An embedded system is like a minicomputer designed for a specific application.
Ugh. I hate computers.
An embedded system can be designed to monitor temperature, time, pressure, light, sound, movement, buttons or touch sensitive capacitive switches, like on the iPod... Infact, an iPod is an embedded system and so is your TV remote and your car alarm, and your alarm clock. An embedded system can have an LCD display, LED, OLED, a piezoelectric sounder, speakers, you name it. It could control motors, lights, actuators, thermoelectic coolers, heating elements... It could be wireless, battery-less...you get the idea.
I'm developing a concept that needs an embedded system. Where do I start? (hand gestures). I'm a designer. I don't know anything about electronics.
We can design and protoype an embedded system for you. All you have to do is tell us what you want it to do. (all laugh)

DTM of Guerledan Lake
This project aims to provide the bathymetry of lakeGuerlédan. Emphasis will be placed on survey design to ensure, as far as possible, full coverageof this geographical area. The resulting bathymetric model will be used by others students as a basis for their oceanographic studies. This Digital TerrainModel (DTM) will then be compared to previous ones.The results will be provided to EDF to support their environmental projects. For these purposes, hydrographic data will be collected to achieve S-44 IHO special order. Requested work: As a first step, the students have to install and configure their mobile mapping system. They will be responsible for ensuring the effective functioning of the system using the patch test and QC procedures. The extends of lake Guerlédan makes it necessary toset priority areas. The latter will be defined by the teacher team together with bathymetric data users. The students will be in charge of the design and conduct of the bathymetric surveys. An initial Quality Check procedure will be systematically applied after each survey to guarantee the data quality. The post processing as well as the DTM comparisons will be finalized at ENSTA Bretagne.
Reference network setup around Lake Guerlédan
The aim of this project is to realize a reference network along Lake Guerlédan. This network will allow the georeferencing of surveys in national 3D (RGF93) and height (IGN69) reference frames. Works to lead:
- Listing of nearby existing markers from French 3D and vertical networks.
- Choice of new markers
- Observation by static GNSS or terrestrial measurements (total station) of markers
- Vertical referencing of new markers to IGN69by direct and/or trigonometric leveling
Low-cost and autonomous hydrographic system
This project aims at designing a low-cost and autonomous hydrographic system. This robotized approach will lead to the acquisition of a digital elevation model (DEM) of the Guerlédan Lake. The project includes the software development of the platform, the installation of several sensors, data processing, and control quality check. The final goal is to obtain a real-time data process including acquisition, processing and quality-check.
Seamless mapping of the shore
This subject intends to construct a seamless digital elevation model (DEM) from land to shallow water. To accomplish this objective, an amphibious off-road vehicule is equipped with a laser scanner and with a single-beam scanning sonar. The challenging part of this project is to merge the data from these two sensors into a single DEM and to analyze the relevancy of data near the water surface.
Using robots for bed-sediment grain size analysis
Bed-sediment grain size is usually studied using high resolution cameras mounted on ROVs (Remotely Operated Vehicles). However, in shallow water or in rivers with varying currents, it might not be possible to use submarines. This project proposes to study the use of 2 types of robots to try to overcome this issue: surface robots and aerial robots. The idea is to build/use robots such as a hovercraft and a multirotor, able to deploy an underwater camera, and process the resulting data to get information on the sediment.
3D reconstruction of immerged objects
The French hydrographic service (SHOM) is interested in testing different bathymetric functionalities of the Kongsberg E M2040C Multibeam echosounder, inorder to detect specific objects such as trees. The aim of this study is to reconstruct 3D underwater objects, comparing the results obtained either with the classic bathymetric method, the extra-detection, and the water column data. These last two methods are supposed to improve the reconstruction of 3D objects. The main results of this study will be discussed and analyzed.
Localization of a plane black box
A plane black box lost on the sea floor should emit a specific acoustic signal that it is possible to detect using hydrophones installed on an autonomous robot. Depending on the signal received, the robot could move and try to localize it, and get asclose as possible. To simplify tests, the acoustic signal of the black box will be considered as the same as the one specified in the corresponding task of the SAUC-E 2016 competition: a 15 KHz sinusoid emitting during 10 ms every second, see http://sauc-europe.org/. Thus, it should be possible to easily generate/record this signal from a standard PC sound card. To set up this experiment, a waterproof box with aniXBlue hydrophone and the corresponding audio amplifier (powered by a 12 V battery) that can be directly connected to the audio output of a PC will be available. This will be used as the black box. The robot used (boat and/or submarine) to localize the black box will be equipped with 2 Aquarian Audio H2a-XLR hydrophones directly connected to the stereo microphone input of the embedded computer (enable Phantom power supply of the microphone input if necessary). The final goal of the project will be to make a demo where the robot can automatically and as accurately as possible go in the direction of the black box by localizing it thanks to its acoustic signal.
Acoustic and oceanographic study of water column
- Acoustic part: The aim of this part is to study water column in order to define if different water masses exist. For this, some acoustic surveys will be lead thanks to single beams at several frequencies. The advantage of multi-frequency is linked to the fact the reflectors don’t have the same behaviour according to its nature (rigid, gaseous, fluid-like…). The recordings of echograms at different frequencies allow us in some cases to distinguish the different reflectors. These surveys can be repeated on several days to put in evidence an eventual temporal evolution.
- Oceanographic part: Surveys of temperature and chlorophyll concentration will be lead at fixed point (temporal sampling) and/or on radiales (spatial sampling). These surveys will be integrated in an oceanographic model at Guerledan Lake in order to put in evidence the water masses and their temporal and spatial variability. A comparison will be done with acoustic data to see if a stratification on temperature would be the explanation of the presence of different water masses at acoustic level.
The first aim of this study is to develop an oceanographic model of Guerledan Lake to simulate pollution cases. Some environmental parameters will be used for model parametrisation and for lake characterization: temperature, chlorophyll, turbidity. Different pollution scenarii will be simulated and these simulations will be used to try to develop anoperational tool that shows how the pollution will be propagated in function of meteorological conditions, pollutant characteristics,… The second aim of this study is to use the oceanographic model of Guerledan to put in evidence the possible presence of seiches.
Dam inspection with a forward looking sonar
Dam inspection can be performed underwater by acoustic means. We will first use a mechanical scanning sonar carried by an in-house rolling carrier and then a forward looking sonar (FLS) carried by a ROV (Remotely Operated Vehicle). This project aims to find the best strategy to inspect the dam of the Guerledan lake given systems capabilities and dam characteristics.


Integration, enrichment, modeling and analysis of data of any kind
HIGGS GALAXY is ideal for processing large-scale quantitative investigation. It contains multi-source data and integrates this low value density information into a unified, quantitative analysis environment.
So far, it is found perfectly suitable for tracking and analyzing data of insurance claims, network trajectory and financial transaction modes. In addition, the results of the analysis have unlimited room for imagination.
With the support of a superb statistical and operational database, analysts will have profounder understanding of data, through building and running the calculation model.
Simple models can be treated as the basis for building more complex models. In this way, building complex analysis becomes a simple, efficient and modular process. Anything that the analysts imagine can be easily and effectively represented.
The interactive user interface of HIGGS GALAXY shows the abstraction of life in various visual forms. Forms, charts and diagrams, seamlessly interact with each other, providing a single, overall visualized view of all interesting data.
The data visualization will synchronize the real-time update of the source data, so users can see the most accurate and updated information at any given time.
Since every new analysis is aimed at providing as many answers as possible, HIGGS GALAXY is built upon the idea of rapid iteration and collaboration.
Analysts can adjust their logic and verify their new hypothesis. by retrospective analysis, analysts update their a priori judgment and ask new questions to provide new evidences for the conclusion.
By applying HIGGS GALAXY and via this mechanism, the enterprise will become more intelligent and keep on this virtuous cycle.

Things to remember when the inevitable shitstorm breaks this afternoon:
The Analog Audio Jack Is Old And Stupid: Old with a capital “O”. This is literally (yes, literally) the same technology Marconi used. People are going to wail and moan, but these are the same people who wailed and moaned when the serial port and the floppy drive was missing from the iMac. Serial ports were old and stupid. Floppy discs were old and stupid and unreliable. Analog audio jacks are old, stupid, unreliable, and they let water into the device. Fail. The wailing and moaning shouldn’t be about the fact that the thing will be gone, the wailing and moaning should be why it took this long to get rid of the damn thing.
Cords Suck: Cords for earbuds suck even worse. The removal of the audio jack isn’t to get people to plug into the lightning port or to make them buy dongles, it’s to get them to stop plugging in at all. Which is why the new iPhone will come with “good enough” bluetooth earbuds in the box. It’s not about a different plug – it’s about no plug.
Megapixels Don’t Equal Quality: More pixels doesn’t make for a better image – processors, lenses, sensors, and software does. Anyone who complains that other phones have cameras with more pixels is simply advertising to you that they don’t really understand digital photography. Image quality counts. Bigger numbers are just for companies that are more marketing than innovation.
WatchOS 3 Really Does Make The Apple Watch A Whole New Device: There is no technology bump – yet – that justifies a new form factor or outright hardware version of the Apple Watch. But there is software that makes the current one less of a specialty item and more of a digital triage device for the masses. New Apple Watch next year – newly usable Apple Watch this year.
New Macbook Pro Models Are Coming: Wait for it.


If your device isn’t charging properly, it could be because the charging port is damaged. To check if the charging port is damaged, first make sure that the charger is working properly. If the charger is working properly, then inspect the charging port for any debris or damage. If there is any debris in the port, gently remove it with a toothpick or other small object. If the port is damaged, you will need to have it replaced.
3 Steps to Know If Charging Port Is Damaged
If the port is bent or damaged, it may be difficult to insert the charger. If the port is loose, it may not make a good connection with the charger. If the port is cracked, it may be letting in water or debris.
In our rapidly changing world, it’s more important than ever to learn how to know if charging port is damaged. With the ubiquity of technology in our lives, we’re increasingly reliant on charging ports to keep our devices powered up. But what happens when your charging port is damaged? If you don’t know how to identify the problem, you could end up stranded without a working phone or tablet. That’s why it’s important to learn how to recognize the signs of a damaged charging port. Charging ports can be damaged in a number of ways. The most common is physical damage, such as from a drop or impact. This can cause the port to become bent or broken, which can make it difficult or impossible
Step 1: If Your Device Isn’T Charging When It’S Plugged In, Or It’S Taking Longer Than Usual To Charge, The Charging Port May Be Damaged
If your device isn’t charging when it’s plugged in, or it’s taking longer than usual to charge, the charging port may be damaged. To check if the charging port is damaged, first make sure that the device is turned off. Then, look at the charging port to see if there is any visible damage, such as bent pins or a broken connector. If there is no visible damage, try charging the device with a different charger to see if the problem is with the charger or
Step 2: You May Also See Signs Of Physical Damage, Like Bent Pins, Around The Charging Port
If you see any physical damage, like bent pins, around the charging port, then it is likely that the charging port is damaged.
Step 3: Another Way To Tell If The Charging Port Is Damaged Is If You Plug In The Charger And Your Device Doesn’T Turn On, Or If It Turns On But The Battery Percentage Doesn’T Increase
One way to tell if your charging port is damaged is if your device doesn’t turn on when you plug in the charger, or if it turns on but the battery percentage doesn’t increase.
Frequently Asked Questions
How Do I Know If Something Is Wrong With My Charging Port?
If the charging port is not working, it could be a sign that there is something wrong with the port.
How Do I Test My Charging Port?
If your device has a removable back panel, you can check the charging port for debris or corrosion and clean it if necessary. If your device does not have a removable back panel, you can use a cotton swab or toothpick to clean out the charging port. To test if the charging port is working, plug in your device to a power source using the charging cable and check if the device charges.
Can You Fix A Damaged Charging Port?
The charging port is the part of the phone that the charger plugs into. If it is damaged, it may be possible to repair it, but it is also possible that the phone will need to be replaced.
If the charging port on your device is damaged, it may not be able to charge the device or it may not charge the device correctly. To determine if the charging port is damaged, try plugging in a different charging cord or try plugging the device into a different outlet. If the device does not charge, the charging port may be damaged.
