Towards uniform benefit-cost analysis for smart grid projects: an example using the Smart Grid Computational Tool
Smart grid technology is being rolled out around the world, with the United States nearing completion of a particularly significant 4 plus billion-dollar Federal program funded under the American Recovery and Reconstruction Act (2009). Under the Climate Change Working Group Implementation Plan, Smart Grid activity comparative analyses are being conducted of benefits estimation methods with example applications to 4 case study smart grid projects, 2 in each country. In this first study, three of eight Southern California Edison's Irvine Smart Grid Demonstration Project sub-project benefits have been analysed over the period 2010-2035. The analysis uses the Smart Grid Computational Tool (SGCT) developed by Navigant Consulting Inc. for the U.S. Department of Energy based on Electric Power Research Institute methods. Results show significant benefits potential for technologies such as distribution voltage and VAR control and utility-scale batteries, while a 22-residence zero net energy home demonstration inspired by California's 2020 residential energy efficiency standard falls far short of economic breakeven at the current stage of costs and technology performance. The experience gathered indicates the SGCT being intended for widespread U.S. smart grid evaluation use is necessarily simple, and consequently has limited applicability for international applications or comparisons.

IBM is setting out to prove not only how wide, but how deep, its computing prowess has become.
In the past year, IBM has begun to lay out its vision of the future based on "pervasive computing" -- making computers more widely available by embedding them in everyday objects -- and "deep computing" -- using supercomputer power to untangle some of the world's thorniest computing challenges.
On Monday, the Armonk, New York-based company will unveil its Deep Computing Institute, a US$29 million research effort to join academic and industry researchers using massive computational power to attack complex problems.
As part of the project, the Deep Computing Institute will publish the source code for its IBM Visualization Data Explorer on the Internet. The powerful software package can be used to analyze and create three-dimensional representations of data.
Deep computing involves using supercomputer-scale machines, advanced software, and sophisticated mathematical formulas to enable researchers to take on daunting scientific and commercial tasks that can involve trillions of variables.
The term was inspired by IBM's Deep Blue chess-playing computer, which defeated world chess champion Garry Kasparov in 1996.
William Pulleyblank, director of mathematical sciences at IBM Research, will serve as director of the institute. Its advisory board will include representatives from academia, government laboratories, and the private sector.
"Deep computing combines the best of business and scientific computing techniques to find the value buried in all this data and to apply that information to solve real-world problems," Pulleyblank said in a prepared statement. "[It] can help find the proverbial needle in an entire field of haystacks, analyzing vast reservoirs of data to uncover key relationships between gene sequences needed to understand disease."
Supercomputers allow researchers to throw maximum data-crunching power at a single research problem or set of problems. Mainframes, their less-powerful commercial siblings, handle general purpose calculations, but are less suited to such intensive research.
IBM is already a top maker of supercomputers -- supplying more than 100 of the world's 500 largest supercomputers -- but the company is pushing to widen the use of the technology beyond academia to a range of new business problems.
IBM has committed more than 120 scientists and technologists in eight research labs -- in New York; San Jose, California; Austin, Texas; Tokyo; Zurich, Switzerland; Haifa, Israel; Beijing; and New Delhi, India, to the Deep Computing Institute. They will collaborate initially on projects ranging from how to schedule personnel in complex environments, such as airline flights, and the modeling of precise weather patterns.
The IBM Data Explorer site will be operational on 26 May, the company said.
Data Explorer uses computational and 3-D graphics-rendering tools in a programmable framework that allows computer users to rapidly create visual images, uncovering patterns, trends, and "what-if" scenarios hidden within highly complex data.
The product could be used by a multinational bank to identify and manage financial risk in portfolios worldwide, for example. In energy exploration, it can depict oil-flow simulations to improve drilling success rates and boost underground reservoir yields.

For several decades, random vibration theory (RVT) has been a popular method for predicting peak ground motions for seismic hazard assessment. Modern usage of RVT is typically in the stochastic method of simulating peak ground motion, to convert empirical models of the earthquake Fourier amplitude spectrum to response spectra, and in site response analysis. This study reexamines the underlying assumptions of RVT analysis, particularly regarding durations, peak factors, and nonstationarity corrections. It is suggested that the significant oscillator duration is the most appropriate duration metric for predicting response spectra, and an empirical model is derived using New Zealand data. This allows RVT to be easily generalized to levels of oscillator damping other than the usual 5%. For short‐duration excitations, signal nonstationarity is accounted for using a theoretical time‐dependent power spectral density function. This allows proper consideration of nonstationarity in both the signal standard deviation and the signal bandwidth. The appropriateness of commonly used Gaussian‐process peak factors is also examined. It is shown that low‐frequency oscillator response signals are not well approximated by a Gaussian distribution, which causes low‐frequency response spectra to be overpredicted. This means RVT‐optimized duration models in the literature do not have a physical interpretation at low oscillator frequencies. RVT analysis only yields approximate results, with standard deviations of 0.25 natural log units. However, it is nevertheless a simple and convenient method for rapidly predicting peak high‐frequency ground motions.

As computers become more complex, the demand increases for more connections between computer chips and external circuitry such as a motherboard or wireless card. And as the integrated circuits become more advanced, maximizing their performance requires better connections that operate at higher frequencies with less loss.
Improving these two types of connections will increase the amount and speed of information that can be sent throughout a computer, according to Paul Kohl, Thomas L. Gossage chair and Regents’ professor in Georgia Tech’s School of Chemical and Biomolecular Engineering. Kohl presented his work in these areas at the Materials Research Society fall meeting.
The vertical connections between chips and boards are currently formed by melting tin solder between the two pieces and adding glue to hold everything together. Kohl’s research shows that replacing the solder ball connections with copper pillars creates stronger connections and the ability to create more connections.
“Circuitry and computer chips are made with copper lines on them, so we thought we should make the connection between the two with copper also,” said Kohl.
Solder and copper can both tolerate misalignment between two pieces being connected, according to Kohl, but copper is more conductive and creates a stronger bond.With funding from the Semiconductor Research Corporation (SRC), Kohl and graduate student Tyler Osborn have developed a novel fabrication method to create all-copper connections between computer chips and external circuitry.
Since the pillar, which is the same thickness as a dollar bill, is fragile at room temperature, the researchers anneal it, or heat it in an oven for an hour to remove defects and generate a strong solid copper piece. Osborn found that strong bonds were formed at an annealing temperature of 180 degrees Celsius. He has also been investigating how misalignments between the two copper bumps affect pillar strength.
“I’ve also studied the optimal shape for the connections so that they’re flexible and mechanically reliable, yet still have good electrical properties so that we can transmit these high frequency signals without noise,” said Osborn.
The researchers have been working with Texas Instruments, Intel and Applied Materials to perfect and test their technology. Jim Meindl, director of Georgia Tech’s Microelectronics Research Center and professor in the School of Electrical and Computer Engineering, and Sue Ann Allen, professor in the School of Chemical and Biomolecular Engineering, have also collaborated on the work.
In addition to this new method for making vertical connections between chips and external circuitry, Kohl is also developing an improved signal transmission line with the help of graduate student Todd Spencer.
“Several very long communication pathways exist inside a computer that require a very high performance electrical line that can transmit at higher frequencies over long distances,” explained Spencer.
This is especially important in high-performance servers and routers where inter-chip distances can be large and signal strength may be significantly degraded. Kohl and Spencer have developed a new way to link high-speed signals between chips using an organic substrate, with funding from the Interconnect Focus Center, one of the Semiconductor Research Corporation/Defense Advanced Research Projects Agency (DARPA) Focus Center Research Programs.
Fabrication begins with an epoxy fiberglass substrate with copper lines on one side. The substrate is coated with a polymer and the areas without copper lines are exposed to ultraviolet (UV) light, which disintegrates the polymer where it’s not wanted. Then, the researchers coat the substrate with another polymer that hardens when exposed to UV light. Layers of titanium and copper are added on top of each copper line. When the layered substrate is heated at 180 degrees Celsius, the first polymer layer decomposes into carbon dioxide and acetone, which diffuse out leaving an air pocket.
“The amount of electrical loss relates to the connection’s sensitivity at higher frequencies,” explained Spencer. “Just having this air pocket there reduces our signal loss greatly.”
The researchers are currently designing a coaxial cable for this chip-to-chip signal link, which should greatly increase the maximum signal frequency the connection can carry.
Companies that make computer chips and package them into a device are very interested in these technologies, said Kohl.
“If these connections can be produced at a reasonable cost, they could be very important in the future because you’re giving the customer a better product for the same cost,” said Kohl.

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

I'm working on an off-grid solar system for work that is going to power some measurement equipment. It consists of 6 240W solar panels, a 60 amp Morningstar MPPT charge controller, an Outback 2.5 kW inverter and a 24 volt, 1820 Ah battery. To keep tabs on the system, we have installed a datalogger with remote communication that sends data via email three times a day. We only have four analog channels and are measuring battery voltage, battery temp, solar charge current, and inverter current. The logger works fine except the inverter current reading fluctuates between 0 and 20 amps with an actual steady load of 10 amps. We are using a 100A hall effect current sensor (offers a higher output voltage than a shunt) and the voltage output reads perfectly steady on a DMM. Today I put a scope on, and found a ripple on the signal, about 300 mV peak to peak (signal is around 2.6 VDC or so), approx 120 Hz. The solar current signal is perfectly smooth so I know it's not the power supply for the hall sensors. I am assuming this ripple is caused by the inverter and the logger's sampling frequency must almost match the 120 Hz or some multiple.
Does anyone have any suggestions on how to remove this ripple? I tried a small cap today and it helped a bit, but I'm afraid of damaging the hall sensor if I go too big on the cap.


New Arrival·Ceramic Package Infrared Products
In the past 20 years, with the rapid development of uncooled infrared detector technology, the technical level and quality of related products have been greatly improved. The cost and reliability of uncooled infrared detectors are becoming more and more important. While the level of packaging technology is an important factor that affects the cost and reliability of uncooled infrared detectors.
Uncooled infrared detectors are currently divided into metal packaging, ceramic packaging, and wafer-level packaging. Metal packaging is the earliest and the best among the three main packaging forms; wafer-level packaging is suitable for mass production; and the ceramic packaging is more favored by the dedicated market for civilian products.
Ceramic packaging is currently the most popular packaging technology on the market. The size, weight and power consumption of the detector can be significantly reduced.
Recently, Global Sensor Technology (GST) releases two ceramic packaging uncooled infrared detectors: GST412C & GST612C. So, why are GST412C & GST612C infrared detectors?
The 400×300 and 640×512 resolution with 12μm pixel size are currently widely used in the mainstream applications in the infrared market.
Mini size: 18.5mm×18.5mm×3.8mm
Light weight: 4.5g
Low power consumption: as low as 80mW
Its compact structure meets more strict integration requirements on size, weight and power consumption.
Under the same resistivity conditions, the vanadium oxide thin film has better TCR, higher photoelectric conversion efficiency, and better measurement temperature stability.
The infrared detector presents clearer, sharper and more detailed image with typical NETD＜40mk.
Based on these two infrared detectors, the TWIN series thermal modules (TWIN412 & TWIN612) are developed.
With enhanced image algorithms and temperature measurement function, the TWIN series thermal module presents more stable images and accurate temperature.
With temperature measurement range of -20℃~150℃/0~550℃(Customizable), accuracy of ±2℃ or ±2% and frame rate up to 30Hz, the thermal module guarantees smooth thermal image and accurate temperature measurement.
The TWIN series thermal module has the advantages of compact design, light weight structure and power consumption as low as 0.8w.
More Emerging Applications
This new product release will give more choices for customers from various industries such as Industrial Automation, Intelligent Security, Unmanned Platform, Robot, Intelligent Hardware, Advanced Driver Assistant System, Firefighting etc.

I tested sending of push notifications to a TV web app and was successful in sending notifications to TV emulators (ver 6.5).
However, after a few sends, I started getting 3008 problem "error of not registered regID". I am sure the regID is right.
I have tried several ways to fix this problem:
(1) register every time the app open
(2) reinstall the app
(3) change the TV emulator
Only (3) was working, although it created the exact same regID, the push notifications started working again. But after some sends, I encountered the same "3008" problem again.


When I setup Foreman (Satellite) server, I didn’t have Ansible support enabled. Here is how it can be done later on.
If we only need Ansible support, it’s sufficient to just run this command:
# foreman-installer \ --enable-foreman-plugin-ansible \ --enable-foreman-proxy-plugin-ansible
Just a note for myself, I also need Remote Execution enabled if I want to run Ansible playbooks as Job Templates.
# foreman-installer \ --enable-foreman-plugin-remote-execution \ --enable-foreman-proxy-plugin-remote-execution-ssh
Note that the remote execution feature is enabled by default on Foreman/Satellite server. The Smart Proxy or Capsule server, on the other hand, must be specifically enabled with the above installed command.

Unlike auralization methods, BRS provides an auditory display based on actual acoustical measurements of the loudspeakers and listening environment - not simulations based on a model of the loudspeakers and room. For this reason, BRS reproductions are significantly more accurate and realistic than model-based auralizations.
BRS measurements of the loudspeakers and listening space are made with an anthropomorphically accurate binaural mannequin equipped with microphones in each ear (see top photo above). Measurements are made at every 1-2 degrees over a range of ±60 degrees by precisely rotating the mannequin's head via a stepper motor controlled by the BRS measurement computer. Each measurement is stored as a set of binaural room impulse responses (BRIR) that provide the filters through which music is convolved and sent to a calibrated pair of high quality headphones (see bottom photo above). A key feature of the BRS playback system is its ultrasonic head-tracker: it constantly monitors the position of the listener's head, sending the angular coordinates to the playback engine, which in turn switches to the corresponding set of measured BRIRs. In this way, the BRS playback preserves the natural dynamic interaural cues, used by humans to localize sound in rooms. Without these dynamic cues, headphones tend to produce sound images localized inside or near the head with front-to-back reversals being quite common. Head-tracking is therefore necessary for accurate assessment of the true spatial qualities of the audio reproduction.
Current and Future Applications For BRS
As a research tool, BRS offers greater efficiencies and opportunities in how audio scientists research, develop and test audio products within home, professional and automotive listening spaces. BRS allows an unlimited number of acoustical variables to be manipulated, sequentially captured, and later evaluated in a highly repeatable and controlled manner. Using BRS, Harman researchers can do perceptual experiments and product evaluations that would otherwise be impractical or impossible using conventional in situ listening tests. This includes double-blind, controlled comparisons of different audio systems in different automobiles, concert halls or arenas, and home theaters.
BRS has already been used at Harman to study how the acoustical properties of the loudspeaker and listening room interact with each other, how these interactions affect the sound quality of the music reproduction, and the extent to which listeners’ adapt to the room acoustics when listening to multichannel audio systems ,. Over the next few years, BRS will help expand our current scientific understanding of how listeners perceive sound in rooms, so that we can optimize the sound quality of loudspeakers, acoustic spaces, and room-correction devices used to tame loudspeaker-room interactions. A BRS auditory display connected over the internet to a BRS database could even allow consumers to compare and select their most preferred loudspeaker model, concert hall seat, or automotive audio system configuration, without ever leaving the privacy of their home.
Finally, BRS brings enormous efficiencies, flexibility, and cost savings to psychoacoustic research and testing. The acoustical complexity of an automotive audio system can be captured and stored as a relatively small 10 MB file, which can then be emailed and evaluated anywhere in the world using a relatively inexpensive auditory display. The high costs associated with building expensive ITU-R listening rooms, transporting listeners, automobiles, and loudspeakers around the world for evaluation may soon be a thing of the past.
In the next installment, I will discuss some of the inherent errors found in all BRS systems, and how they can be removed through proper calibration. Some recent listening experiments will be described that validate the perceptual accuracy and performance of our BRS system.

Technical Paper Abstract
The world is abuzz with talk of the next industrial revolution, Industry 4.0. Digitization, smart technologies, machine-to-machine communications, Internet of Things deployments, the list goes on, and on. All of these innovative concepts will benefit from the standardized exchange of information between all levels of an industrial system. New products will evolve over time, but existing technologies can be adapted now to leverage the massive installed base of CIP-enabled products around the world. One such technology that is gaining acceptance is OPC UA. Many vendors, end users, and industry consortia have converged on OPC UA as a vendor-neutral mechanism to exchange data. ODVA and OPC Foundation are jointly developing a CIP Companion Specification to support this data exchange.
This paper documents the approach taken by that joint working group to map the CIP information model to the OPC UA information model. With this mapping, applications utilizing OPC UA and its associated companion specifications can obtain data from CIP devices without the need to understand CIP. This solution will easily bring value to end users seeking to extract more data from existing installations for their evolving application needs.

The discovery of laser induced ultrafast magnetization dynamics by Beaurepaire et al. has stimulated an intense research activity and opened up a new field in condensed matter physics. Even after two decades of studies and debates, the mechanisms of ultrafast demagnetization remain disputed. In order to bring new experimental information into this field, and with the advent of femtosecond X-rays sources, we decided to use time resolved soft X-rays based pump/probe techniques. Indeed, contrary to IR and visible radiation, X-rays can be easily turned into an element-specific and local probe of the magnetization. First I will show results obtained by time-resolved small angle x-ray scattering on granular FePt. Then I will present results obtained by time-resolved x-ray resonant magnetic reflectivity on Ni thin films. In conclusion I will give some outlooks on questions that soft x-ray could help to solve in this field.


Welcome to EpoS Wizard!
Looking for some information on a J2 580 POS system
I am looking for anyone who might know about the magstripe reader in the J2 580 POS system.
I have extraced one, and I am looking at interfacing it with something else, and would like to know the pinout and function. I know on the j2 580 it acts like a keyboard, I would like it to act as a keyboard on a normal computer as well.
I don't believe it can be done. The interface board inside the J2 takes the signal input from the reader and converts that into a USB type input so it's read as a keyboard wedge.
Why on earth would you want to do this anyway? You can buy a USB mag card reader from eBay for about a tenner.
I like messing around. I have one on the way. But wanted to see if I could make this one work.

Infrared technology advancements have led to an expansive set of infrared applications in both the private and public sectors. New materials and manufacturing techniques have continued to reduce the cost while improving the quality of infrared cameras, but the cost is still high when compared to the cost versus quality of visible light spectrum cameras. Innovative image processing techniques can be implemented to help bridge this gap between the cost and quality of infrared cameras. The goal of this research is to improve the overall quality of infrared imaging by fusing short-mid wavelength infrared images and long wavelength images of the same background and objects. To achieve this goal, infrared camera theory as well as image fusion theory will be first introduced to provide adequate background knowledge. Then, the setup of the experiment and calibration of the two infrared cameras will be described in details. Next, the image registration and fusion procedures will be presented by Matlab software. The results of this research show that the fused images have higher quality than individual short-mid wavelength infrared images and/or long wavelength images.

Learning associations across modalities is critical for robust multimodal reasoning, especially when a modality may be missing during inference. In this paper, we study this problem in the context of audio-conditioned visual synthesis – a task that is important, for example, in occlusion reasoning. Specifically, our goal is to generate future video frames and their motion dynamics conditioned on audio and a few past frames.
Predicting the future frames of a video is a challenging task, in part due to the underlying stochastic real-world phenomena. Prior approaches to solve this task typically estimate a latent prior characterizing this stochasticity, however do not account for the predictive uncertainty of the (deep learning) model. Such approaches often derive the training signal from the mean-squared error (MSE) between the generated frame and the ground truth, which can lead to sub-optimal training, especially when the predictive uncertainty is high.


It could also dramatically lighten the load for people who can't connect to a power grid, including soldiers who now must carry many pounds of batteries for a three-day mission -- all at a reasonable price.
The researchers say that in the long term, mass-production could bring the per-unit cost of power from microengines close to that for power from today's large gas-turbine power plants.
Making things tiny is all the rage. The field -- called microelectromechanical systems, or MEMS -- grew out of the computer industry's stunning success in developing and using micro technologies. "Forty years ago, a computer filled up a whole building," said Professor Alan Epstein of the Department of Aeronautics and Astronautics. "Now we all have microcomputers on our desks and inside our thermostats and our watches."
While others are making miniature devices ranging from biological sensors to chemical processors, Epstein and a team of 20 faculty, staff and students are looking to make power -- personal power. "Big gas-turbine engines can power a city, but a little one could 'power' a person," said Epstein, whose colleagues are spread among MIT's Gas Turbine Laboratory, Microsystems Technology Laboratories, and Laboratory for Electromagnetic and Electronic Systems.
How can one make a tiny fuel-burning engine? An engine needs a compressor, a combustion chamber, a spinning turbine and so on. Making millimeter-scale versions of those components from welded and riveted pieces of metal isn't feasible. So, like computer-chip makers, the MIT researchers turned to etched silicon wafers.
Their microengine is made of six silicon wafers, piled up like pancakes and bonded together. Each wafer is a single crystal with its atoms perfectly aligned, so it is extremely strong. To achieve the necessary components, the wafers are individually prepared using an advanced etching process to eat away selected material. When the wafers are piled up, the surfaces and the spaces in between produce the needed features and functions.
Making microengines one at a time would be prohibitively expensive, so the researchers again followed the lead of computer-chip makers. They make 60 to 100 components on a large wafer that they then (very carefully) cut apart into single units.
The MIT team has now used this process to make all the components needed for their engine, and each part works. Inside a tiny combustion chamber, fuel and air quickly mix and burn at the melting point of steel. Turbine blades, made of low-defect, high-strength microfabricated materials, spin at 20,000 revolutions per second -- 100 times faster than those in jet engines. A mini-generator produces 10 watts of power. A little compressor raises the pressure of air in preparation for combustion. And cooling (always a challenge in hot microdevices) appears manageable by sending the compression air around the outside of the combustor.
"So all the parts workS. We're now trying to get them all to work on the same day on the same lab bench," Epstein said. Ultimately, of course, hot gases from the combustion chamber need to turn the turbine blades, which must then power the generator, and so on. "That turns out to be a hard thing to do," he said. Their goal is to have it done by the end of this year.
Predicting how quickly they can move ahead is itself a bit of a challenge. If the bonding process is done well, each microengine is a monolithic piece of silicon, atomically perfect and inseparable. As a result, even a tiny mistake in a single component will necessitate starting from scratch. And if one component needs changing -- say, the compressor should be a micron smaller -- the microfabrication team will have to rethink the entire design process.
For all the difficulties, Epstein said the project is "an astonishing amount of fun" -- and MIT is the ideal place for it. "Within 300 feet of my office, I could find the world's experts on each of the technologies needed to make the complete system," he said.
In addition, the project provides an excellent opportunity for teaching. "No matter what your specialty is -- combustion or bearings or microfabrication -- it's equally hard," he said. "As an educational tool, it's enormously useful because the students realize that their success is dependent upon other people's success. They can't make their part easier by making somebody else's part harder, because then as a team we don't succeed."

Infographic: Critical communication at the crossroads
Moving beyond traditional PMR / LMR
How can critical communication systems best take advantage of modern mobile broadband standards like LTE?
Conformity to the MCPTT standard is one essential aspect to consider, the challenging spectrum allocation another. This infographic takes a glimpse at the PMR / LMR ecosystem and presents a way how broadband technology could be integrated even into established networks without the need to replace the entire existing infrastructure.


Prototype Nearly Finished
Yey!, my prototype is nearly finished with the exception of auto temp starting!, well in the shed anyway. Not actually tested it with film yet.
It may look a bit of a mess, but the logic is that once it’s refined, I’ll think of a better housing etc. At this point, I can easily move wires, adjust kit and reprogram without any hassle or dismantling.
So a quick tour!
Ok, first the temp modules are fitted at the top for easy visual reference. I havent labelled them yet but the idea is you just plonk the sensors in the chemicals or water bath and they read the temps. I havent linked the two arduinos yet to trigger an ‘auto start’ system but will do in the near future.
Next, the two main displays that will show instructions, and the main development timer for visual reference when the machine is running.
I’ve then mounted the arduino at the side for each USB access for reprogramming if needed. Note I’ve hot glued the wires down when I was 100% sure I was happy where they are. Just as they can easily pop out when kit is moved.
I’ve then wired the dev tank up, which connects via a removeable 12v DC lead. The tank will sit in the waterbath, with the top electrics and lid well-above the water line.
The panel, although scruffy looking serves the basic purpose and the light up buttons work well.
The blue light lights on agitation as well.


As we are not still able to make it work, I have few questions.
About the wiring, we are not sure about DEN signal - we have connected it to the EMX LCD_EN - is it correct? DISP signal should be just on/off so it is just 1 - display is really on so I presume there is no problem.
According to a datasheet I set the following LCD configuration via FEZ config:
@ Marten - The display you are using is one of the ones that our recently announced Display NHVN supports. You can always compare its schematic with your board to see if the pins are connected correctly. The timings you listed are correct.
Thank you guys for hints. The problem was the we have connected pin no. 35 to the logical 1 and it should really stayed NOT CONNECTED as it’s in the pin description documentation. Now it’s working like a charm.


Why do we need so many blockchains?
- blockchain All Things Web3
New blockchains are launching constantly. It is hard to follow everything that is happening in Web3 space.
Do we really need that many blockchains? How do you see the future of landscape of blockchains?
I think this is an interesting topic. I expect number of new blockchains without a real break-through innovation to continue growing until real adoption of the blockchain technology happens in the world. New blockchain will have to be 10x better than widely adopted once to get a real interest. Currently we are in the stage of active innovation and experimentation with the technology.


The Laser Revolutionized the Manufacturing Industry Optical components that support the laser processing technology at its core
The term laser is an acronym for light amplification by stimulated emission of radiation. A laser beam is an intense artificial light obtained by converting electrical energy into light energy and amplifying it. The energy density of the laser beam is about one million times that of light in the natural world. In 1960 in the United States, the world’s first laser oscillation was achieved. Since then, laser performance has improved phenomenally and various laser oscillators and applications have been developed. The features of lasers include monochromaticity, high directivity, light convergence and high energy density. Utilizing these features in the 1980s, laser began to be introduced in the field of materials processing. Lasers enable noncontact, flexible and fast machining (e.g. cutting, welding and drilling). They first penetrated manufacturing worksites in the steel and automotive sectors. Since the 1990s, being recognized as an essential technology, practical use of lasers has advanced in the manufacturing of electronic components for cellular phones and digital home appliances, such as liquid crystal displays and semiconductors, as well as in circuit patterning and other micromachining and the manufacturing of components for 3D printers.
The key components used to exploit the full potential of a laser cutting machine are optical components that include the lenses through which the laser beams converge and mirrors that reflect the beams. The Sumitomo Electric Group developed zinc- selenide (ZnSe) lenses for CO2 laser cutters in 1985. Since then, Sumitomo Electric has provided diverse types of optical components to meet market needs. The laser is one of the greatest inventions of the 20th century and is said to play a leading role behind the scenes in modern society. In what follows, we explore the Sumitomo Electric Group's history and future in the development of optical components for laser processing.


Spanish researchers have carried out a preliminary study using an electronic tongue based on potential multistep pulse voltammetry, in combination with multivariate statistical techniques to detect and quantify sugar syrup in honey. Pure monofloral honey (heather, orange blossom and sunflower), sugar syrup (derived from rice, barley and maize), and samples simulating adulterated honey with different percentages of syrup (2.5, 5, 10, 20 and 40) were evaluated. An automatic, electrochemical system for cleaning and polishing the electronic tongue sensors (Ir, Rh, Pt, Au) significantly improved the repeatability and accuracy of the measurements. PCA analysis showed that the proposed methodology is able to distinguish between types of pure honey and syrup, and their different levels of adulterants. A subsequent PLS analysis successfully predicted the level of the adulterants in each honey, achieving good correlations considering the adjusting parameters. The measurement system here proposed has the potential to be a quick and effective option for the honey packaging sector. However, much further work is needed to see how effective this technique is with a wider range of monofloral honey, blended honey and commercial sugar syrups.

News provided byTrinaTracker
Sep 18, 2023, 10:00 PM ET
CALDAS, Colombia, Sept. 18, 2023 /PRNewswire/ -- TrinaTracker, the leading smart solar tracking solutions provider which is part of Trina Solar Co Ltd (SHA: 688599), has signed a solar tracker supply agreement with Power Construction Corporation of China (POWERCHINA), to supply the Tepuy Solar PV Park in Colombia with 108MW of smart tracking systems, including TrinaTracker's pioneering Vanguard 1P trackers, smart algorithms and Trina Smart Cloud platforms.
The Tepuy Solar PV Park is in the province of Antioquia province, northwestern Colombia. It is developed by Medellin Electric Power Company, the largest power generation company in the country. POWERCHINA undertakes EPC that includes the design, supply, construction, installation and commissioning of the PV power station. TrinaTracker is the exclusive supplier for the project.
TrinaTracker's Vanguard 1P trackers are designed for large solar power plants on flat terrain. The design requires fewer driving systems and controllers per megawatt, thus reducing material costs and saving on labor hours during project installation. Fewer pile foundations make the product a better match for cleaning robots, and bi-damper systems reduce the chance of trackers being damaged in high winds.
TrinaTracker's smart tracking system is integrated with the tracker structure + algorithm + platform, and it includes tracker control unit, SuperTrack, and Trina Smart Cloud monitoring platform. The system can increase power generation up to 8% compared with that of conventional solar tracking systems. It also provides better monitoring functions of trackers during system operation, thus reducing client operational and maintenance costs, and decreasing losses of power generation.
Latin America is one of the most important markets for solar trackers, and Colombia, one of the largest economies in the region, has huge potential for the development of photovoltaic power generation. The international consulting company S&P Global says more than 80% of ground photovoltaic sites in Latin America use solar trackers, with market penetration significantly higher than the 45% global average.
TrinaTracker's collaboration in the Tepuy project augurs well for more growth in the Latin American market. By introducing the most advanced smart solar tracking technology to the region and providing comprehensive system design, delivery and after-sales service, TrinaTracker will continue to drive the development of photovoltaic projects in Latin America, adding more much-needed green energy to the region.
