www.vsharing.com: With the development of the Industrial Internet of Things （IoT）, what are the core issues that need to be addressed?
David Lucchetti：关于需要解决的核心问题，我们认为最主要可以从三个方面来分析。第一个核心问题是工业物联网推广发展过程中的标准问题，从工业4.0概念的产生，工业物联网始终处在一个发展进程当中，物联网的实现并非简单的技术问题，需要涉及整个物联网的生态系统，不同环节相关领域的合作协调，以及信息安全，甚至用户数据隐私保护等各种问题。因此，只有建立相对统一的标准，工业物联的各个环节在同一标准内才能更有效的沟通发展，其中环节有包括设备物联、数据物联、信息分析、信息处理反馈等等。第二个核心问题，是建立这样的一个标准之后我们如何进行具体实现。它也需要有一些具体相关的操作，包含比如各个环节的技术投资、基础建设投资等等方面。第三个核心问题就是关于工业物联网技术的更深层次的认知程度，技术的积累与分享，比如今天大家参与的ECV上海希为主办的第二届中国人机交互国际峰会也是重要的分享活动之一。在工业物联相关领域内，各环节行业都有了更深刻更广泛技术储备和技术探讨，并加以具体实现， IIOT也会有更加长远的发展。
David Lucchetti: Regarding the core issues that need to be addressed, we believe they can be mainly analyzed in three aspects. The first core issue is the standard problem in the development of industrial IoT. Since the creation of concept of Industry 4.0, the Industrial Internet of Things has been evolving all the time. The realization of the Internet of Things is not a simple technical issue, but involves the entire ecosystem of the Internet of Things including the cooperation and coordination of different aspects, information security, and even user data privacy protection. Therefore, only by establishing relatively unified standards can all aspects of the Industrial IoT communicate more effectively. Such procedures include equipment IoT, data IoT, information analysis, and information processing and feedback. The second core issue is how we implement it after establishing such a standard. It also needs to implement some specific measures, including technical investment and infrastructure investment of all procedures. The third core issue is about the greater awareness of industrial IoT technology, the accumulation and sharing of technologies. For example, ECV Shanghai Xi’s Second China Human-Computer Interaction International Summit we participate in today is one of the important sharing events. In the relevant fields of IoT, if they conduct more in-depth and extensive technology discussions and sharing, IOT will have greater development in the long-term.
www.vsharing.com: As a global leader which has been immersed in industrial automation for many years, how does STMicroelectronics emphasize the importance of HMI in industrial automation?
David Lucchetti: HMI plays an irreplaceable role in the industrial automation. It is the trend of industrialization development, and will make industrial production more intelligent and more efficient, and industrial environment more secure. Along with the development of the ecosystem, combined with the progress of hardware and software technologies, HMI will have a wider range of applications such as: predictive failure maintenance, remote monitoring and maintenance, industrial system automation optimization, product packaging, logistics and transportation testing, etc. Researches show that predictive maintenance of industrial equipment can not only report the hidden problems of the equipment in advance and effectively extend the service life of the industrial equipment.

The new application of artificial intelligence can help predict volcanic eruptions
China] satellites can provide data on global active volcanoes, but researchers have been committed to using these data to predict the risk of volcanoes. This idea is likely to be realized soon, because the current algorithm can automatically calculate volcanic risk data signals, so as to help scientists establish a global volcanic early warning system within a few years
michaelpoland, a scientist from the Yellowstone Volcano Observatory in Washington, D.C. (a department of the self regulatory chaos survey led by the leading U.S. Geological polyurethane insulation enterprise), said that without these algorithms as auxiliary tools, geologists would not be able to keep up with the pace of satellite information. Andrew Hooper, a volcanologist at the University of Leeds in the United Kingdom, led the development of an algorithm. He said that this algorithm should benefit about 800million residents who live near the volcano, especially in the modified and high value-added use of engineering plastics such as cars. "About 1400 volcanoes may erupt on the sea," he said. "About 100 of them are under monitoring, but most of them are not monitored."
at the American Geophysical Union meeting (AGU) held in Washington, D.C., this week, the meeting is held every six months and shows two methods of predicting volcanic eruptions. In the past few years, with the launch of European Space Agency satellites sentinel 1a and sentinel 1b, the field of Volcanology has devoted itself to observing the movement of land around volcanoes. Sentinel 1 satellite uses a technology called radar interferometry, which can compare the radar signals sent to and reflected from the earth to track the changes of the planet's surface
this method is a commonplace, but it is worth mentioning that every six days, sentinel 1 satellite will re detect every location on the earth, and sentinel team can quickly receive these high-resolution observation results. In the UK, a research team called the center for structural observation and modeling of earthquakes and volcanoes (comet) has begun to build a snapshot database of ground motion called "interferograms" for the world's volcanoes. Hooper, who cooperates with comet, said that considering that the pattern detection of learning machines is quite successful in other fields, we naturally thought of using automatic detection coverage to cover this database
the change of ground motion can usually reflect the magma movement under the volcano, but it can not fully predict the volcanic eruption. Unlike hot spots or ash plumes that can be automatically detected by hot weather satellites, ground movements can help predict volcanic eruptions, not just indicate their occurrence. "Moving doesn't always mean that volcanoes will erupt," Hooper said. "But there are few cases where volcanoes erupt directly without moving."
in order to achieve this goal, the team must teach them b) divide the important, rare, obvious and pointer according to the instigation type at the end of measurement; The algorithm cannot easily confuse the atmospheric changes of ground motion. To this end, Hooper SMM: Recently, the team used a technology called independent component analysis, which can decompose the signal into different parts: such as stratified atmosphere or short-term turbulence, and the ground displacement of volcanic craters or flanks. This technology enables them to capture the latest ground movement or movement rate changes, both of which may be signs of future volcanic eruptions
at the same time, another comet team led by Juliet Biggs, a volcanologist at the University of Bristol, UK, used artificial intelligence to build a second algorithm, called convolutional neural network. The researchers first used the original interferogram from ENVISAT, the predecessor of sentinel, to train their neural networks. They have some examples of volcanic eruptions. Although the algorithm has made some progress in analyzing 30000 sentinel interferograms, its prediction results are still unsatisfactory. Fabin albino, another volcanologist in the group, said that at present, they have only a few research examples, and for learning machines, thousands of examples are needed
to solve this problem, Biggs and her colleagues created a synthetic data set simulating volcanic eruptions. Albino said that as more sentinel examples are uploaded to the algorithm, the prediction results will become more and more accurate

USB Flash Security is a program that will password-protect your USB memory devices. With these devices becoming cheaper and of a higher capacity, it is now very common to have one or more of them around to help you transfer information from one computer to another. This implies a security risk. Unauthorized users might access the information in your USB memory. Besides, you may get a virus when plugging your pen drive in another computer.
This free application avoids these hazards by protecting your USB memory devices with a password that will be checked by a small program that this utility installs into your USB device. If you do not enter the right password, you will not be able to access the information stored in it, and the system will just recognize it as a 0 bytes unit. You will not be able to save anything on it, either.
The program will recognize every USB flash memory plugged in your system, and will offer you the possibility of installing itself in some or all devices available. An important caveat: when installing this utility all the information already existing in that device will be lost. Therefore, you should perform a backup before installing USB Flash Security. Likewise, when you uninstall this utility, this operation will also erase all the information stored in the USB memory.
- It is free
- It locks your USB devices totally
- It cannot be installed in a device or uninstalled from it without losing all your information

If you would like to purchase or discuss the possibility of acquiring one of our betavoltaic products. Please click the button below to contact us:
Betavoltaic Power Sources
Currently Widetronix is proud to offer customers the Firefli.™
We have two models of this device, the T and N, which are housed in a power electronics package (right) comprised of a metal package plated with gold. This seam sealed package provides sufficient shielding and prevents radioactive material from escaping. The electric current flows out of the two leads connected to the package sidewall.
Firefli-T: is designed to meet a customer specific voltage and current profile. The design flexibility allows for the betavoltaic to produce 10’s to 100’s of nanowatts and run for years or decades depending on application. The Firefli-T uses tritium (12.3 year half-life) that has been locked into a metal foil. The amount of tritium contained in the package ranges from 25 mCi to 2.5 Ci. The initial power output for the device can be set to 10 nW to 1 µW, with the open circuit voltage set in 2V increments, typically ranging from 2V to 6V.
Firefli-N: This device is configured in the same way as the Firefli-T, except that the isotope used is Nickel-63 (100.1 year half-life). The Nickel-63 is plated on to a foil and the amount contained in the package ranges from 5 mCi to 500 mCi. The initial power output for the device can be set to 5 nW to 500 nW, with the open circuit voltage set in 2V increments, typically ranging from 2V to 6V.
Surface Mount Options
Widetronix is releasing a surface mount package in mid-2013. The custom ceramic surface mount package is designed specifically for use with betavoltaics and is 10 mm x 8.5 mm x 2mm. The low profile package is hermetically seam sealed, providing protection from radiation exposure and contamination. In addition it can be stacked vertically (below), which allows for increased power output while minimizing footprint.
Firefli Enabled Electronics
Widetronix has successfully integrated our betavoltaics with electronic devices and has developed two other products that can run autonomously for more than 25 years.
The first is the Widetronix Real Time Clock (RTC). Our betavoltaic power source is able to run the clock and can communicate with electronics via standard I2C or SPI communication. The RTC is equipped with a watch-dog timer, which can enable a microcontroller to remain in sleep mode, conserving power, until the betavoltaic enabled RTC wakes it up for activity. In addition, the betavoltaic provides certainty that the clock will function for years, beyond that of conventional battery power sources.
Widetronix has also combined their betavoltaic power source with a microcontroller called a Power Burst Controller (PBC). The betavoltaic provides the power to run it in sleep mode and then periodically wake it up to perform specific functions. This is ideal for duty cycled applications that need to perform limited computations on a periodic basis. The microcontroller can be combined with sensors and RF or RFID components to collect, store, and transmit data. The development opportunities with this device are endless since the power is being maintained by the betavoltaic and therefore the lifetime of the overall device can span for decades.
If you have any product related questions concerning the above information, please use our web form on our contact page to enable a discussion about the possibility of acquiring betavoltaics.

This will be a quick post since I’m tired…I finished the code for the Arduino door lock.
(Watch the second video in HD to see the LCD display)
General Logic of Code:
The user (aka Noelle or I) enters the passcode via the LCD shield. If the passcode matches the numbers in the code, the Arduino will turn the servo. The servo will be attached to our door lock, so the rotating servo will turn the lock. If the incorrect code is entered, a “Try Again” message will appear. I tried to make the code modular by breaking it up into functions. The two main functions consist of entering the number and turning the servo.
Complications & Other Notes:
(1) I haven’t had the time to solder the wires to a circuit board, so the connection between the servo and the Arduino is terrible. As a result, I have to fiddle with the servo wire (in the uploaded video) before the servo receives the signal to turn.
(2) The uploaded video of the working arduino/servo was recorded early this afternoon. After recording the video, I continued to fiddle with the circuit. It was during this period of time that I accidentally shorted the servo. (Accidentally attached servo power to ground and ground to power–oops! But the two pins were so close to each other…) So now the servo is fried. Frown. Anyway, I put in an order to Amazon this afternoon, but that means I can’t tinker with circuit to try to get a better connection until I get the replacement servo. Lesson learned though: check power/ground connections before turning on power source!!!
(3) I opened up the servo to see the gears on the inside since it’s pretty much useless now. Pictures below!

Review of the Xiaomi Mi 10 phone
The new Xiaomi Mi 10 is already on sale in the market (not to be confused with the Mi 10 Pro), it offers a strong «iron», good cameras and a large battery. But let’s understand more and look at the test results, which will give a clear idea of what is Xiaomi Mi 10 and whether it is worth taking at all.
- Housing: Gorilla Glass 5 back and front, rounded edges, metal frame, splash protection

Testing the display
The main feature of the screen on the new Mi 10 is the refresh rate of 90 Hz. This is a Super Amoled matrix with a Full HD resolution and a pixel density of 386 ppi. The resolution is not the highest – competitors have higher resolution, but you can’t see the pixelation on the screen.
- Max. white brightness: 854 CD/m2
- Max. black brightness: 0 CD/m2
- Contrast: ∞
- Minimum color rendering error DeltaE: 1.7
Test results indicate that the screen on Mi 10 is good. The smartphone is also certified to play videos with HDR 10+ (Widevine L1 DRM support level). This means that any streaming services will be able to give you high-quality video with HDR, but the other thing is that they are rarely used
Battery and autonomy
The Xiaomi Mi 10 has a battery capacity of 4780mah, and this is even more than the Xiaomi Mi 10 Pro. In any case, we are primarily interested in testing results.
- Continuous conversations: 26: 53 h (screen off)
- Wi-Fi web surfing at 200 CD/m2 brightness (90 Hz): 14: 44 h (15: 24 h at 60 Hz)
- Video playback at 200 CD/m2 brightness (90 Hz): 18: 57 h (21: 29h at 60 Hz)
- Charging speed: 20% in 30 minutes, 53% in 30 minutes, 91% in an hour, 100% in 1 hour and 12 minutes
Xiaomi has done a very good job of optimizing power consumption, making the Mi 10 one of the most Autonomous flagships on the market.
The Mi 10, unlike most other flagships, has full-fledged stereo speakers. In the GSMArena test, they showed an excellent result. Below is a screen from the test, the closer LUFS is to zero, the better:
Processor and performance
One of the key features of the flagship is the Snapdragon 865 processor with an X55 modem that provides connection to 5G networks. Of course, this will be useful in the future, but not today. Also Snapdragon 865 is equipped with 8 cores: 1xKryo 585 Gold 2.84 GHz + 3xKryo 585 Gold 2.42 GHz + 4xKryo 585 Silver 1.8 GHz. The adreno 650 coprocessor is responsible for the graphics, which is also quite powerful.
Processor testing results are below + comparison with competitors.
GeekBench 5.1 (multi-core):
- iPhone 11 Pro Max (Apple A13 Bionic) – 3503
- OnePlus 8 Pro (Snapdragon 865) – 3374
- Xiaomi Mi 10 – 3322
- Huawei P40 Pro (Kirin 990) – 3197
GeekBench 5.1 (single-core)
- iPhone 11 Pro Max (Apple A13 Bionic) — 1332
- OnePlus 8 Pro (Snapdragon 865) – 902
- Xiaomi Mi 10 – 895
- Huawei P40 Pro (Kirin 990) – 780
- Xiaomi Mi 10 – 578056
- OnePlus 8 Pro (Snapdragon 865) – 573276
- iPhone 11 Pro Max (Apple A13 Bionic) – 536883
- Huawei P40 Pro (Kirin 990) – 496356
Xiaomi Mi 10 delivers the highest performance results. It is in the top League along with the Top flagships of other brands.
The Xiaomi Mi 10 has a Samsung Bright S5KHMX ISOCELL camera with a resolution of 108 MP. This is a large 1/1.33 inch sensor with 0.8 µm pixels. It is used together with a lens with stabilization and an f/1.7 aperture. the same basic sensor is used on the Mi 10 Pro, but there is also laser focusing.
The lack of a telephoto camera was a disappointment, but the wide – angle camera remains – its resolution is 13 MP, the optics are f/2.4. The rest of the cameras – the macro and the sensor depth.
Naturally, when shooting during the day, the quality of photography is high: the level of detail is impressive, the dynamic range is wide, the colors are accurate, and the contrast is high, but the noise occurs in an area of monotonous sky or grass. The smartphone also demonstrates high-quality shooting in low light, but these are all subjective assessments.
Mi 10, like Mi 10 Pro, can record videos in 8K/30 FPS resolution. Of course, other popular modes are also available: 4K at 60/30 FPS, Full HD at 60/30/120/20 FPS. Moreover, shooting from the main camera in 4K mode is conducted with optical and electronic stabilization; the video quality is generally high. Sample videos below:
The Xiaomi Mi 10 is a great flagship that is worse than the more advanced Mi 10 Pro with only a camera. But it is cheaper, and there is a high-capacity battery inside, and this is with the same physical size of the smartphone. In Russia, the device costs 54-55 thousand rubles, and you can safely take the phone for this money.
- Design and housing made of Gorilla Glass 5, there is protection from splashes
- Fast and accurate fingerprint scanner in the screen
- Smart OLED screen with 90 Hz refresh rate
- High battery life + fast charging with 30W adapter included
- Cool stereo speakers and high quality sound
- Snapdragon 865 + 5G
- High quality photos and videos from the main camera
- There is no full protection from water IP68
- No body camera and optical zoom as a result. There is a 2x zoom, but this is a crop from the main camera
- The wide angle camera is weak in poor light
- The quality of shooting on the front camera is mediocre


Avoid this network mess:
Now, Let’s talk speed
There is no substitute for network speed in computing. All things equal: the faster the network connection, the better the computer experience. Wired connections are generally faster than wireless connections. Use a speed test tool to verify speeds via a browser.
At my house I use Spectrum (unbundled) to connect to the internet. Their home package promises 100 Mbps (megabytes per second) download and 10 Mbps upload speeds. In reality, depending on network conditions in the home, download speeds may be slightly to significantly lower; this is usually dependent on the network adapter used.
The wired network adapter I use in my desktop computer is capable of gigabyte (1,000 Mbps) speeds, so 100 Mbps should be easy. Still, when I run Speedtest.net by Ookla, I get 92.07 Mbps download and 11.09 upload speeds. Upload speeds exceed expectations while download speeds are lower than promised. When I turn off the wired adapter and switch to a 2.4 Ghz USB wireless adapter on the same computer, I receive a disappointing 8.73 download speed and 6.04 upload speed. What a difference!
I use a refurbished Netgear R6400 router for my home network which is connected to a Cisco gigabyte switch for additional wired ports. This router is capable of both 2.4 Ghz and 5 Ghz channels for wireless connections. I now switch to my ex-chomebook which I converted to a laptop (see my article: https://jansen-pcinfo.com/2019/11/30/my-75-laptop/). Connecting at 5 Ghz, my network speed is 47.97 download and 11.97 upload. So, my download speed is roughly half of my wired network speed on the desktop computer while the upload remains about the same. When I switch to 2.4 Ghz on the laptop I get 42.62 download and 8.63 upload speeds. The 2.4 Ghz results in lower speeds.
Looks like it is far better to use a wired connection, but, if wireless, use the 5 Ghz channel whenever possible.
A word about upload speeds
Most people concentrate on download speeds when talking about the internet, but upload speeds are important too. The answer lies in packets: a small bit of information exchanged between computers. Without being too complicated, a packet is sent by the server computer upon the request of the client computer, the client computer then uploads an acknowledgement that the packet was received. This exchange is done millions of times for a computer to receive a full file. Of course, upload speeds are important when backing up files to the cloud or when live streaming video files as well.
The only way to get wired connections in the home is to run cable. In my home which is a ranch, I have to make runs of over 50 feet. Originally I purchased bulk Category 5 cable and a termination kit with twisted pair connectors. A picture here is worth a thousand words:
I found (the hard way) that these connections can be unreliable. Using a tester, I found that the cable did not terminate properly – some wires did not connect end to end.
It is much better to purchase a patch panel and punch down tool (again a picture):
The patch panel allows all 8 connections to terminate properly and the excess wires are cut off by the punch tool. The bulk cable lengths can also be estimated better making for less excess cable hanging all over the wiring location.
From there I purchased 10 – 1 ft Category 6 cables to connect between the patch panel and my router switch combination. This makes for much cleaner and reliable connections for my home network.
Sure, it is a lot of work to establish solid wired connections throughout the home, but the payback is less buffering when watching on a Smart TV, and better speed for all household computers.


Solar energy is obtained from the radiation of the sun and in that manner, it is widely available, renewable and energy source that is clean. The solar thermal technology is used in harnessing the solar energy. The heat can be directly used or changed into energy that is mechanical which is electricity. The sun is a very great source of solar energy and it very affordable and environment friendly. This article provides the benefits of solar energy
Solar energy is ideal as it provides energy that is renewable and clean. It serves to reduce the dependency on natural gas and electricity production, oil and coal. This fuel source of energy releases emissions that are unsafe thus responsible for global change, affects water and soil and quality of air. In addition to that, due to the great advantage of solar energy to be clean, it does not pollute the environment. Since the solar energy is clean, it does not pollute the ecosystem. The solar power that is abundant offers the source energy that is unlimited and is not harmful to the ozone layer.
With solar energy, you can be controlling and have freedom over your electricity. Installation of the solar panels, will help you gain energy independence as your residence is powered by solar panels at the top of the roof at daytime and energy stored in the battery at night. Home batteries and solar panels are more accessible, affordable, efficient and resilient. If the next storm is striking or power going off the solar power offers energy and peace of mind to homes. In addition to that the home battery system supplies the energy derived from the sun by removing expenses of refueling a gas, uncertainty, and inconvenience.
The solar energy will assist one to save on the current bill of utility. Home solar panels can be offsetting your costs if you are undergoing rising expenses of energy. Solar will be offering annual savings and efficiency even in cloudy and colder seasons. The orientation and efficiency compared to the sun, is dependent on size and it will provide more energy than the one needed. For this reason, it will be reducing the electric monthly bills to zero and it is seen it is the most affordable source of energy. It is not hard to be installing and operating the solar panel since the main source of energy is the sun.
Another important factor of solar energy is the federal availability which is increasing the solar panels to be affordable. In this regard, many people can be accessing the solar energy at an affordable rate. The tax of the federal solar credit will give you a reduction against the federal tax income. Supplementary, the solar panels can be improving the value of the resale of your house.


Standard Model of Particle Physics
| Chemistry can be understood in the
physics of 3 particles (proton, neutron and electron), and the influence of the
electromagnetic force. Nuclear physics can be understood in the physics of 4 particles
(proton, neutron, electron and electron neutrino), and the influence of the strong and
weak nuclear forces together with the electromagnetic force. The Standard Model Theory (SM)
of particle physics provides a framework for explaining chemistry and nuclear physics (low
energy processes). It additionally provides an explanation for sub-nuclear physics and
some aspects of cosmology in the earliest moments of the universe (high energy processes).
The Standard Model is conceptually simple and contains a description of the elementary particles and forces. The SM particles are 12 spin-1/2 fermions (6 quarks and 6 leptons), 4 spin-1 gauge bosons and a spin-0 Higgs boson. These are shown in the figure below and constitute the building blocks of the universe. The 6 quarks include the up and down quarks that make up the neutron and proton. The 6 leptons include the electron and its partner, the electron neutrino. The 4 bosons are particles that transmit forces and include the photon, which transmits the electromagnetic force. With the recent observation of the tau neutrino at Fermilab, all 12 fermions and all 4 gauge bosons have been observed. Seven of these 16 particles (charm, bottom, top, tau neutrino, W, Z, gluon) were predicted by the Standard Model before they were observed experimentally! There is one additional particle predicted by the Standard Model called the Higgs, which has not yet been observed. It is needed in the model to give mass to the W and Z bosons, consistent with experimental observations. While photons and gluons have no mass, the W and Z are quite heavy. The W weighs 80.3 GeV (80 times as much as the proton) and the Z weighs 91.2 GeV. The Higgs is expected to be heavy as well. Direct searches for it at CERN dictate that it must be heavier than 110 GeV.
The matter and force particles of the Standard Model. Up and down quarks were observed for the first time in electron-scattering experiments at SLAC in the late 1960s. The 1990 Nobel Prize in physics for this discovery was awarded to SLAC's Richard Taylor and to Jerome Friedman and Henry Kendall from MIT. The charm quark was discovered simultaneously in experiments at SLAC and at Brookhaven in 1974. SLAC's Burton Richter and MIT's Samuel Ting shared the 1976 Nobel Prize in physics for this discovery. The tau lepton was discovered at SLAC in 1975, for which SLAC's Martin Perl was awarded the 1995 Nobel Prize in physics.
The SM particles are considered to be point-like, but contain an internal spin (angular momentum) degree of freedom which is quantized and can have values of 0, ½ or 1. Spin-1/2 particles obey Fermi statistics, which have as a consequence that no 2 electrons can be in the same quantum state. This feature is necessary for forming atoms more complex than hydrogen. Spin-1 and spin-0 particles obey Bose-Einstein statistics, which prefer to have many particles in the lowest energy or ground state. This phenomenon is responsible for superconductivity.
|The Standard Model says that forces are the exchange of gauge bosons (the force particles) between interacting quarks and leptons. Feynman diagrams are useful to describe this pictorially. As illustrated in the figures below, two electrons may interact by scattering and exchanging a photon; or an electron and positron may collide and annihilate to form a Z particle, which then decays into a quark and anti-quark. Electromagnetic forces occur via exchange of photons; weak nuclear forces occur via exchange of W and Z particles; and strong nuclear forces occur via exchange of gluons. Electromagnetic forces and interactions are familiar to everyone. They are responsible for visible light and radiowaves, and are the physics behind the electronics and telecommunications industries. All quarks and leptons can interact electromagnetically. Strong nuclear forces are responsible for holding protons and neutrons together inside the nucleus, and for fueling the power of the sun. Only quarks interact via the strong interaction. Weak nuclear forces are responsible for radioactivity and also for exhibiting some peculiar symmetry features not seen with the other forces. In contrast to electromagnetic and strong forces, the laws of physics (ie. the strengths of the forces) for the weak force are different for particles and anti-particles (C Violation), for a scattering process and its mirror image (P Violation), and for a scattering process and the time reversal of that scattering process (T Violation). All quarks and leptons can interact via the weak interaction. The Standard Model provides much more than simply a description of electromagnetic, strong and weak interactions. Its mathematics provides explicit and accurate calculations for the rates at which these processes take place and relative probabilities for decays of unstable particles into other lower mass particles (such as for a Z particle to decay into different types of quarks and leptons).|

iPhone creators, Apple is said to be working on a facial recognition feature for the coming iPhone 8, that will replace the Touch ID fingerprint sensor entirely. With this feature, iPhone users will be able to unlock the phone instead of a finger print.
According MyBroadBand, Apple’s redesigned iPhone, set to go on sale later this year, Apple is testing an improved security system that allows users to log in, authenticate payments, and launch secure apps by scanning their face, according to people familiar with the product. This is powered by a new 3-D sensor, added the people, who asked not to be identified discussing technology that’s still in development. The company is also testing eye scanning to augment the system, one of the people said.
The sensor’s speed and accuracy are focal points of the feature. It can scan a user’s face and unlock the iPhone within a few hundred milliseconds. It is designed to work even if the device is laying flat on a table, rather than just close up to the face. The feature is still being tested and may not appear with the new device. However, the intent is for it to replace the Touch ID fingerprint scanner, according to the person. An Apple spokesman declined to comment.
In testing, the face unlock feature takes in more data points than a fingerprint scan, making it more secure than the Touch ID system, the person said. Apple introduced Touch ID in 2013 with the iPhone 5s for unlocking the phone and it added support for authenticating payments and logging into apps a year later.
After Samsung’s Galaxy S8 fail with the similar feature, Apple’s solution is said to be more secure because it is using 3D depth perception, preventing it from being bypassed by 2D pictures. According to Mac rumours, Bloomberg warns that the feature is “still being tested” and that Apple could have decided to nix it, so it continues to be unclear if the iPhone 8 will indeed abandon its Touch ID feature for the new under development face recognition.
Rumours surrounding Touch ID in the iPhone 8 have been all over the place during the course of the last few months. Apple was rumored to be having difficulty embedding the Touch ID fingerprint sensor under the display of the device and explored other solutions including a rear Touch ID button, but the company’s final solution remains up in the air. In recent dummy models and part leaks show a display without a Touch ID button, suggesting it’s either under the display or non-existent.
Today’s report also includes a quick mention that Apple is testing faster displays with ProMotion technology for the iPhone 8. ProMotion display technology, which features a 120Hz refresh rate for improvements to motion and animations, was first introduced in 2017 iPad Pro models.
Seems like Apple is working day and night to impress its fans who are yet to find out if the feature I a complete success.

The S8 Mini will be launched soon. Th S8 Mini will have a 5.3-inch screen and the Infinity display and nearly bezel.less design of the phone will make the dimensions of the phone match with a smartphone with a 4.7inch screen with 16:9 aspect ratio.
It is also being heard that the S8 mini will be a downgrade in terms of specs, comparing the S8 and S8 Plus. S8 mini will feature Qualcomm Snapdragon 821. It is not clear that whether the phone will have a 3 GB or 4 GB RAM.
Samsung’s another flagship, the Galaxy Note 8 is touted to be launched during the IFA event in Berlin, and hence it is expected that the S8mini will also be launched along with the Note 8.


Acuparse RaspberryPi Direct Connection Guide¶
This is a community provided guide moved into the docs from the Wiki. It was designed to help you with installing Acuparse on a RaspberryPi when using an Access or SmartHUB directly connected to the Pi.
What is a RaspberryPi¶
RaspberryPi's are a small single-board microcomputer, that is fairly inexpensive (most kits are under 40USD) and are powerful enough to run Acuparse sufficiently. The OS used in this document will be Raspbian Bullseye (a version of Debian Linux).
The two current versions of RaspberryPi that are available are the RaspberryPi Zero W (RPi0W) and the RaspberryPi 3 ( RPi3). While the RPi0W will work, it's not recommended for performance reasons and limited ports (a single MicroUSB port and built-in WiFi). The RPi3 performs very well, and also provides 4 standard USB 2.0 ports and a built-in 10/100 Mbps Ethernet port and WiFi.
Overview of the setup¶
- RaspberryPi 3
- MicroUSB power supply (2.1A or higher, a powered USB hub can also work)
- Case (Optional but recommended)
- MicroSD card (16GB or 32GB, Class 10 recommended)
- MicroSD to SD card adapter
- USB Ethernet adapter (optional if you want a wired connection to your router instead of WiFi)
Note: MicroSD cards are not created equal. Choose a fast performing card to use with Acuparse. It does a large amount of reading and writing! See microSD Card Benchmarks for assistance selecting the right MicroSD card.
In addition to the above parts, you will need an Acurite SmartHub or Acurite Access, and a computer with an SD card reader (either built-in or a USB adapter. This is for the initial set up of the MicroSD card).
NOTE: RPi3 kits can be purchased from sites such as Amazon that include the Pi, power supply, case, and even MicroSD card. Here are some example Amazon links for the items above:
- RaspberryPi 3 Kit - Includes Pi, Power Supply, and Case
- 32 GB MicroSD with SD adapter
- USB Ethernet Adapter - This is optional if you want a wired connection to your router instead of WiFi
If you decide to use a Pi Zero W instead of a Pi 3 (not recommended as noted above), then you will have to have a MicroUSB Ethernet Adapter like this to connect your SmartHub / Access as described in this project.
Hardware set up description¶
The SmartHub or Access will be connected directly to the RPi3 via an ethernet cable to the RPI3's built-in ethernet port. The RPi3 will then connect to your local LAN either via the built-in WiFi, or via a wired ethernet cable to your router using a USB Ethernet adapter. The RPi3 will be "headless" (i.e. no monitor, keyboard, or mouse attached) in this setup.
See Additional Information below for important details you may need to complete you install.
Install Raspbian Buster onto the MicroSD¶
Follow this guide for setting up your MicroSD card: How to Install or Upgrade to Raspbian Bullseye . The Buster install directions are still valid for the Bullseye release. Use the Light image for your installation. When completing your wpa_supplicant file, add a new line with
scan_ssid=1 that is between the
psk= lines .
If you are going to connect your Pi directly with a wired network cable (not using WiFi), then you can skip the wpa_supplicant file creation altogether. Also, if you are using a Windows computer to connect to your Pi, you will need to Download PuTTY for the terminal program to access it via SSH. For most modern PC's you will choose the 64bit MSI Windows Installer, and then double click / run the downloaded file to install PuTTY.
Pi networking setup¶
Now we need to do some setup of the networking on the Pi. In a terminal window connected to your Pi, do the following command:
sudo apt-get update && sudo apt-get -y install dnsmasq iptables-persistent
A couple of screens will come up during the iptables-persistent part of the install. Choose "No" (use the tab key to select the NO option) on each of these and hit enter to confirm.
At this point, make sure your SmartHub / Access is powered on and connected to your Pi via a network cable to the built-in ethernet port. Also, if you are going to use a wired connection for your LAN, make sure the ethernet adapter is connected to your Pi and a network cable is connected and attached to your local network.
Now, we need to determine the network adapter names. Run the following command on your Pi:
Look at the left-most column for the names of your adapters. Wired network adapters will have names similar to eth0 and eth1. WiFi will have a name similar to wlan0. (NOTE: Depending on initial configuration, sometimes the names will be longer and include the MAC address for the device). In our set up, eth0 will be the built-in network port on our Pi and where we will plug in the SmartHub or Access. If you are using WiFi to connect to your LAN, then wlan0 will be for your LAN connection. If you are using an ethernet adapter, then that should be like eth1 for your LAN connection.
Now issue the following commands:
sudo mv /etc/dnsmasq.conf /etc/dnsmasq.conf.orig
sudo nano /etc/dnsmasq.conf
This will put you into a new file you are creating. Now copy and paste the following:
server=18.104.22.168 # Use Google DNS
interface=eth0 # Use interface eth0
dhcp-range=eth0,192.168.6.50,192.168.6.100,255.255.255.0,24h # IP range and lease time
If you're using wired LAN, change the 4th line to:
Hit Ctrl-X to exit and choose Y and hit enter on the file name that comes up.
Now do the following:
sudo nano /etc/dhcpcd.conf
Go to the bottom of the file and add the following lines. You will want to make sure that the first two static lines, match your LAN address for your router. If your router is not 192.168.1.1 you will need to change both of those lines so that the address of your Pi and your Router address are in the same subnet (usually 192.168.0.x or 192.168.1.x for most routers). Also, if you are using a wired network adapter then change the line with wlan0 to eth1. Don't change the static IP under the eth0 line (this is setting up a new network for the Acurite Hub device). Then Ctrl-X to save your changes.
# Home LAN
interface wlan0 # Change to eth1 if using wired adapter
static ip_address=192.168.1.70 # Set the Pi IP address
static routers=192.168.1.1 # Your router's IP
# SmartHub / Access network
Now we need to edit the hosts file:
sudo nano /etc/hosts
At the bottom of the hosts file add the line for whichever Acurite device you are using:
192.168.1.70 hubapi.myacurite.com # If you are using a SmartHub
192.168.1.70 atlasapi.myacurite.com # If you are using an Access
NOTE that the IP needs to match what you set for the Pi IP address in the dhcpcd.conf file previously.
Now run the following commands (if you are using a wired connection for your LAN, change wlan0 to eth1 in the 4th and 6th command:
sudo iptables -F
sudo iptables -X
sudo iptables -t nat -F
sudo iptables -A FORWARD -o wlan0 -i eth0 -s 192.168.0.0/24 -m conntrack --ctstate NEW -j ACCEPT
sudo iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
sudo iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
sudo netfilter-persistent save
At this point, the editing and network configuration is all complete. To make sure there are no issues, do the following commands:
sudo systemctl restart networking.service
sudo systemctl restart dnsmasq
If there are no errors, reboot your Pi as follows:
sudo reboot now
Wait a minute or two for the Pi to reboot. Now when you ssh to it, you will be connecting to the static IP you set up for it (in the above edits, it would have been 192.168.1.70 unless you changed this).
Run the following commands:
curl -O https://gitlab.com/acuparse/installer/-/raw/master/install && sudo bash install | tee ~/acuparse.log
If that fails, try:
wget https://gitlab.com/acuparse/installer/-/raw/master/install && sudo bash install | tee ~/acuparse.log
You will be prompted through the installation for passwords and such. As long as there are no errors after the installation completes, you will need to open a browser to point to your Pi's address (example:
http://192.168.1.70). Then follow the prompts to complete the setup of your Acuparse environment.
This doc is somewhat outdated and needs to be tested/updated with newer OS releases. As such, the details provided below should SUPERSEDE any configuration above. This doc will be updated in a future release with the correct process.
eth0, you need to edit the
/etc/dhcpcd.conf file and put an entry in like the following (Replace the
192.168.86.1 address with your router address):
static domain_name_servers=192.168.86.1 22.214.171.124
And the second is to modify the kernel parameters:
/etc/sysctl.conf file uncomment the
ip_forward line for ipv4 to make it persistent across reboots:
You can change that and either run
echo 1 > /proc/sys/net/ipv4/ip_forward or
sudo sysctl -p to enable it.
If you're using bullseye, the legacy
eth1 names will go away and you'll see interface names starting with
enx########## where the ## is replaced with the mac address. Those names can be used, or you can put in a link file in
/etc/systemc/network with a number prefix such as
10-network.link that looks like:

Digital face recognition lock is based on biometric access and is one of the modern emergency locksmith services.
Digital locks are designed to replace secure access method with mechanical keys. two main reasons for this replacement are:
- problems people have with using the key
- frequently need to use residential and commercial locksmith services. For instance, Problems like losing the key and having to ask an emergency locksmith to change the lock.
Digital lock accesses are non-duplicatable, especially biometric accesses including face, palm and fingerprint recognition.
This feature is essential for business owners and commercial locksmiths because security plays a vital role in business.
According to 24 hour locksmith, the fingerprint is one of the safest types of biometric access.
Because identification can be made with living tissue, in this case, the diagnostic sensor can not be deceived by having a fingerprint pattern.
Of course, among biometric approaches, face recognition has weaknesses and problems compared to other methods.
This article of the Swift Emergency Locksmith will discuss face recognition models and their function in digital lock. We also describe the problems and weaknesses of digital face recognition locks.
Face Recognition Lock Function
The most basic face recognition process finds similar things, and practically no face matching is done.
The second type is found in smartphones and digital locks. Several photos are taken of the person’s face, and these photos are stored in the digital lock database or phone.
When the user is near the lock, the face pattern matches the images in the database. If matched correctly, the door will open for you.
This is called FACE ID. Installation and repair of these locks are one of the common services of a residential and commercial locksmith.
Types Of Face Recognition Sensors
Face recognition sensors in digital locks are divided into two-dimensional and three-dimensional types.
Two-dimensional face recognition sensor has more weaknesses than three-dimensional; the depth of the face, like the depth of the forehead or the angles of the nose, is not recognized.
Therefore, you can easily deceive the device’s sensor through photos or videos and unlock the digital lock in the two-dimensional type. 24 hour locksmiths prefer 3D face recognition over 2D.
In 3D face recognition sensors, in addition to face angle detection, face recognition is performed in a digital lock with invisible infrared light or IR sensor.
The IR sensor calculates the return time of infrared rays from different face angles to the sensor.
Digital Face Recognition Lock Problems
One of the important things that disrupt the facial recognition process is extra accessories on the face. Items such as masks, glasses and hats make it difficult to recognize faces in digital locks.
The next item is facial gestures. Laughter and frowning, for example, can cause facial recognition problems because images are introduced to the smart lock with standard angles.
According to 24 hour locksmith, another weakness of the digital face recognition lock is the number of faces introduced to the lock; the more faces, the more time for the matching process.
It is said that the face recognition lock is done up to a distance of one meter. But most of the time, you have to get very close to the digital lock to be identified.

Hyperion (GSE DAQ/Control)
Mounted inside the Ground Operations Device (G.O.D.) box, Hyperion is the main ground support board. Through a point-to-point WiFi connection, ground support commands are relayed through a terminal computer to Hyperion, where Hyperion is able to control valves accordingly. In addition, Hyperion also acquires data during testing and fueling. This raw data from sensors is converted to digital data, then stored on the terminal computer in the G.O.D. box. Data sources include load cells (for thrust and fuel tank measurements), pressure transducers (for engine chamber and oxidizer tank measurements), as well as several thermocouples mounted on various parts of the ground support equipment and vehicle.
Once fueling is complete, the ground software waits for confirmation to continue. When confirmed, it then initiates an auto-sequence through Hyperion. This auto-sequence tells the system how to go about actuating valves, igniting electronic matches to set off explosive bolts to disconnect gas lines, and initiating the ignition sequence that's overseen by the vehicle's onboard electronics.
In order to operate all the elements of the ground support system, and leave room for future expansion of the system, Hyperion has the ability to control 8 servos with positional feedback, supply 4 solenoids with up to 8 amps of current, set off 6 electric matches, take raw data from up to 24 bridge sensors (used as load cells or pressure transducers) and 16 thermocouples and covert all the analog data to digital. This has to be handled in real time so that there is live control of the rocket during the fill and other pre-ignition steps, as well as live data streams to the base camp. Hyperion communicates through UART to a USB interface with the G.O.D. computer, sampling and saving each of the data inputs at 100 Hz, with a live data stream back to the base camp at 10 Hz.

AFP – Google on Thursday unveiled a tool that lets scientists and defenders of the environment use the Internet to keep an eye on what is left of the Earth’s forests.
“We hope this technology will help stop the destruction of the world’s rapidly-disappearing forests,” Rebecca Moore and Amy Luers of the US Internet giant’s philanthropic arm Google.org said in a blog post.
The technology lets scientists analyze raw satellite imagery data and extract information such as locations and measurements of deforestation or even regeneration of forest.
The system is hosted in the Google “cloud,” the technology firm’s Internet-linked data centers, and has the potential to reveal in seconds when forests are being chopped down, burned or bulldozed.
“Being able to detect illegal logging activities faster can help support local law enforcement and prevent further deforestation from happening,” Moore and Luers wrote.
Emissions from tropical deforestation are comparable to the emissions of all of the European Union, and are greater than those of all cars, trucks, planes, ships and trains worldwide.
Google demonstrated a prototype of the technology at the UN climate talks in Copenhagen.
The forest-tracking system is being tested by a small group of Google partners and will be made available as a not-for-profit service, according to Moore and Luers.


Think of QR codes as more information in less space. QR codes are 2D barcodes that can store more than 4,000 alphanumeric characters in a limited horizontal and vertical space. A traditional linear (1D) barcode can only hold roughly 20 horizontal characters. QR Code Authentication utilizes a QR code on a printed badge or Label that acts as a contactless card. Instead of using a traditional card reader, a computer’s internal camera is utilized to read the QR code—no additional hardware required. This form of authentication is ideal for quick authentication and tracking system and Use QR codes to create landing pages and capture email addresses.

Renovus Solar’s primary focus is to save customers money by installing solar energy systems. These systems consist of interconnected technological solutions that convert sunlight into electricity through the Photovoltaic (PV) process. PV modules, made up of small photovoltaic cells, generate electricity and are connected to create an array of modules. The DC power produced by these modules is converted into AC power using an on-site inverter. Depending on the customer’s needs, a solar power system may have four or five components that work together to offset energy bills and promote energy independence.
When properly installed, solar panels convert the sun’s energy into DC electricity. Sunlight comprises minuscule particles called photons, which radiate from the sun. As these hit the silicon atoms of the solar cell, they transfer their energy to loose electrons, knocking them clean off the atoms.
Freeing up electrons is, however, only half the work of a solar cell: it then needs to herd these stray electrons into an electric current. This creates an electrical imbalance within the cell, which acts like a slope down which the electrons will flow in the same direction. This flow of electrons is the DC current that will be fed into your inverter.
When the sunlight hits a solar cell, its photons are converted into electrons of DC electricity. This type of electric current is not directly applicable either at your home or business and cannot be sent through the grid for use elsewhere.
Inverters allow you to convert DC power to AC power, which can be used by your home or transferred back to the grid. Modern inverters are also smart devices that allow solar array owners to monitor their system’s production in real-time.
A utility meter helps consumers track how much solar power is produced throughout the day. Utility meters are also known as net energy meters. Net meters keep track of the energy you consume and the energy you produce.
Energy credits are applied to your total net energy usage when your system is producing more energy than you are using at that given moment. If your meter is offsite, as with a community solar system, those credits are applied to your bill monthly rather than instantaneously.
While not all residential and commercial systems have on-site energy storage, they become increasingly more common as industry prices decrease. Energy storage systems are available to anyone who has a solar system, be it in their home or off-site.
Energy storage systems have the dual benefit of allowing consumers to use energy from their battery during peak-pricing hours and store it in case of a grid outage. Batteries are connected directly to a home or business inverter and come in various sizes depending on the consumer’s energy demands.
All Renovus solar energy systems are still connected to the grid. The reason for this is that grid-connected systems are both more reliable and easier to maintain for consumers.
The grid can buy back energy from consumers when their systems are overproducing and supply the necessary power to keep a home or business running smoothly when the system is not at peak performance.


Kenya on Friday, May 11, 2018, launched its first locally produced satellite into space, hoping “to go into the books of history.”
The nano satellite precursor flight (1KUNS-PF) will be the first outer space object registered by Kenya, the University of Nairobi, whose team developed the satellite, said in a statement.
The team was hoping “to make history” by venturing into space science, said the university’s vice chancellor, Peter Mbithi.
The satellite, which is only 10 centimetres high and able to provide limited earth observation and audio broadcast, was launched by the Japan Space Agency in Tokyo at 1000 GMT.
If the flight is successful, the scientists of the university plan to develop bigger, high-resolution satellites “with serious scientific and technological value for the country,” according to the statement.
Kenya is now hoping to launch its own space programme at the cost of between 500,000 dollars and one million dollars per year, the university said.
Commercial satellites have considerable economic potential for Kenya, including earth mapping, land use, weather forecasting, food security mapping, disaster management, coastline and border monitoring, forest management and wildlife monitoring.
Kenyan scientists are already collaborating the with United Nations Office for Outer Space Affairs, the Japan Aerospace Exploration Agency and University of Rome in Italy to boost innovation in Kenya.
