Here is a quick guide to troubleshooting your HONDA CB550 (or CB500, CB750, etc.) electrical system and testing all of the system’s components with regard to the question “Why is my battery not charging?“. While this guide may be of interest to all curious readers who want to find out how to test alternators, voltage regulators and rectifiers, it is intended to help those who have a battery that is not charging and who have ensured that all 3 of the following conditions apply: 1) the correct type and size of battery is installed and 2) all original electrical system’s components are present, and 3) the battery is not charging when the bike is running.
REQUIRED TOOLS: A multi-meter (voltmeter, ammeter, ohmmeter).
RECOMMENDED READING: ELECTRICAL SYSTEM BASICS
CHECK THE BATTERY.
Use your voltmeter and check the battery’s voltage. A good battery should read 12.6 V or more. If the voltage is less than 12.6 V, charge the battery using the correct battery charger.
If the battery is not charging, skip the rest of this post and get a new battery.
(It may be possible to “rescue” the battery. Check the fluid/acid level. If a little low and the battery is relatively new, say a few months old, top up to the correct level using distilled water and try charging the battery again. If the level is too low, say half way, and the battery is about a year old or older, “rescue” is unlikely.)
If the battery is charging properly when connected to a battery charger, skip to the CHECK THE WIRING section.
If you don’t have a battery charger, you may want to operate the horn (or headlight in hi beam) for about 30 seconds. The horn will sound loud (the headlight will not fade noticeably), if the battery is good. Repeat that a day later. A good battery will operate the horn (or headlight) since it will re-charge itself to some degree overnight. A bad battery will not.
PERFORM A CHARGING TEST.
Start the bike and let it idle. Connect the voltmeter to the battery’s terminals. It should read around 12 V, more if the battery is fully charged. Increase the RPM. The voltage should gradually increase to 14 V or slightly more at 4,000 RPM and above. Switch the multi-meter to AMP mode. At idle, the reading should be around 6 A and that reading should decrease as the RPM increase going to about 1 A at 6,000-7,000 RPM. NOTE: If the headlight is on, the initial reading at idle speed may be 2-3 A.
If both the voltage and amperage readings are as given above, the electrical system is functioning normally. If the battery is not charging, skip the rest of this post and get a new battery.
If the readings are not as shown above, read on.
CHECK THE WIRING.
Inspect all the wiring connecting the battery, the voltage regulator, the alternator and the rectifier to the extent possible. You’re right. That’s much easier said than done. A good deal of it is not easily visible, let alone accessible. Repair or replace any cut, broken, worn out, fraying or damaged wires. Check all connectors and ensure all terminals are intact and clean. The idea here is to make sure all components of the electrical system have the means to “communicate” with each other via good clean electrical wires and connections. Perform the CHARGING TEST again. 90% of charging issues could probably be solved after checking the battery, the wiring and all connections and connectors. If the problem persists, read on.
CHECK THE ALTERNATOR.
As you may recall from the ELECTRICAL SYSTEM BASICS post, the alternator generates electricity by means of a magnetized coil (the field coil) rotating inside a stationary coil (the stator coil). The coils, as their name implies, consist of long copper wires coiled around some piece of metal sometimes in strange shapes. The longer the copper wire the greater its resistance and we can measure that.
Disconnect the wiring harness that comes from the alternator at the connector located at the electrical box behind the left side cover. You will know it is the correct one because there will be 3 yellow wires, a white wire, a green wire and a couple of other wires in it. In the image below, the purple arrow points to it:
Connect one of the leads of the ohmmeter to the green wire and the other to the white wire. (You’ll recall that the electrical power that magnetizes the field coil arrives from the voltage regulator via the green and white wires). You will be measuring the resistance of the field coil. It should be around 5 Ω. The original HONDA specification is 4.9 Ω +/- 10%. If the reading is 6 Ω, there is no need to panic. The measured resistance is probably greater than the actual resistance since the connections between the terminals in the connector and your ohmmeter are not perfect and some additional resistance is coming from the wires. If the resistance is infinite or extremely low, somethings is wrong. You might want to disassemble the alternator assembly and see if the resistance measured at the field coil itself is within spec. Maybe there was a bad connection or a wire was shorted when you took the readings at the connector? Clean and repair the wires and connections as needed. If the reading is still out of spec, replace the field coil. It’s very easy to do.
Now, connect one of the leads of the ohmmeter to any yellow wire in the connector and the other lead to another yellow wire. Do all possible combinations. OK, let’s make this a little clearer. Let’s call the three yellow wires Y1, Y2 and Y3. Connect one of the leads of the ohmmeter to Y1 and the other to Y2. Record the reading. Keep Y1 connected, but now connect the other lead to Y3. Record the reading. Disconnect the lead from Y1 and connect it to Y2. Keep Y3 connected where it is. Record the reading. That’s all. All readings should be around 0.4 Ω. HONDA’s specification is 0.35 Ω +/- 10%. I normally get readings around 0.5 to 0.6 Ω and I am not worried. The higher reading is, again, due to imperfect connections between the ohmmeter and the terminals in the connector, and hence some additional resistance. If the resistance is infinite or extremely low, somethings is wrong. You might want to disassemble the alternator assembly and see if the resistance measured at the stator coil itself is within specification. Maybe there was a bad connection or a wire was shorted when you took the readings at the connector? If the reading is still out of spec, replace the stator coil. It’s very easy to do.
Perform the charging test again. If there is very low or no electrical current generated by the alternator, it is possible that the voltage regulator is not sending any power to the field coil, which in turn cannot get magnetized and hence no electricity is generated.
CHECK THE VOLTAGE REGULATOR.
Where is this thing? Just follow the white and green wires and they’ll lead you to it. In the image below, it is the gizmo on the left with the black-white-and-green sticker on it.
Disconnect the black white and green wires, undo the bolts/screws that fasten the voltage regulator to the box and remove it. Then undo the screws holding the cover and remove it. You should see this:
There are two gaps that need to be checked, cleaned and adjusted, if necessary. Refer to the picture above and check the core gap. It should be 0.6 to 1.0 mm. Adjust if necessary. Check the point gap. It should be 0.2 mm. If the points are pitted, clean them and polish with 600 grid sandpaper prior to adjustment.
You can verify that the voltage regulator sends electrical current to the filed coil by applying a 12 V electrical current (directly from the battery, for example) to the black (+) and green (-) wires. A voltmeter connected to white (+) and green (-) should indicate that electrical current is coming out of the voltage regulator. Depending on the amount of current going in, the secondary resistance circuit will remain open or will close and you will see that if the cover is off. If no current comes out of the voltage regulator, replace it.
Perform the charging test.
CHECK THE RECTIFIER.
If the my-battery-is-not-charging problem has not been solved yet,… something must have gone wrong while performing all previous checks, inspections and adjustments described above. You might as well start over. Chances that the rectifier has failed are so slim indeed. Rectifiers have no moving parts and are so simple in principle (consisting only of a few diodes) and in construction that the likelihood of them failing is next to nothing. Check for physical damage, broken connections, broken ribs in the housing, anything that would indicate the problem is on the outside. It is located at the bottom of the electrical box behind the left side cover.
If you must test the rectifier, disconnect the rectifier connector. There will be 5 wires: three yellow, a red/white and a green.
To test it, first take a look at the rectifier’s schematics and try to remember how it works. Wires 1,2 and 3 in the image below are the three yellow wires coming from the alternator and carrying alternating current. The diodes convert that alternating current to direct current and that current goes to charge the battery via wire #4.
The testing principle is this: there should be continuity in the “normal” direction, i.e. in the direction of the black arrows and no continuity in the opposite direction. To be clear, if current is coming in through wire #1, it should come out of wire #4 (and only out of #4; it cannot go elsewhere). Your ohmmeter will send an electrical current in order to read the resistance to that current. So, if you see no continuity when you connect #1 and # 4 together through the ohmmeter, reverse the leads and there should be a beep and continuity. If there is continuity in both directions or no continuity in both directions, the rectifier, incredible as it may be, is not functioning properly and should be replaced.
I hope this helps.QUESTIONS?


Two perpendicular signals can't really do much phase cancelation as they are not oriented properly to do so. Cancelation happens in parallel phases--0 or 180 degrees
I'm not sure this is right. Maybe you're thinking of the power
the cap alone. The power over time is zero, since it gives back the same
amount of current as it stores over time. It's the current and voltage
is 90deg out of phase
But, what we have here is adding voltage to voltage
from the neck PU to the bridge PU. If they are 90 deg out of phase the sum is far from zero.(se pic the purple curve is the sum)
In fact, the only time we have a complete cancellation is 180 deg out of phase,
If you have 0 deg (= in phase) you would double the output signal.
In the pic the purple curve is the sum.
Please let me know if I'm wrong here!

Dark Fiber is a fiber optic cable with no light passing through it. It is also referred to as unlit fiber. A Dark Fiber, fibre optic cable is a data communication cable that has not been activated and is not connected or utilised yet.
Since the installation of fibre optic cable is typically complicated and very costly, it is common practice to lay down more cable than initially necessary in preparation for future demand.
Telecommunications companies and Internet Service Providers (ISPs) make use of unlit fiber to provide lit and managed fibre connections to their customers for an ongoing monthly service access fee.
Using single mode (SMF) and multi mode (MMF) Fibre cables, customers benefit from high bandwidth, with long distance and short distance applications respectively.
Fiber Optic cables transmit data through light impulses. Data travels by way of light signals through transmission medium. The speed of light is transmitted about 299,792,458 meters per second, which is approximately 300,000 kilometers per second.
When light travels through a fiber optic cable, its speed is reduced by approximately 30%. At these signal speeds, data transfer can reach about 1000 Mbps or more. (1Gbps+)
To get a better idea of the magnitude of these speeds, in comparison to other broadband connections, an ADSL (asymmetric digital subscriber line) would typically achieve a 7 – 15 Mbps download rate, and a relatively fast 4G mobile network connection could reach 20 – 40Mbps. This makes the fiber optic cable a superior symmetrical data connection, offering uncontended download and upload speeds.
Available in several Australian capital cities:
Sydney, Brisbane, Melbourne, Alice Springs, Darwin, Newcastle, Perth, Adelaide, Hobart, Canberra
Businesses and organisations requiring more control of their data networks, with great performance are well suited for a dark fiber network.
Costs and overall solution will be dependent on the organisation’s specific requirements.
Organisations needing a network with a higher degree of speed, control, security, and scalability should strongly consider dark fiber as a part of their data network strategy.
If your business is interested in Dark Fiber but needs some support in determining the feasibility of the project, CircleBC can provide you with a Dark Fiber Consultant who can help you work through the process of determining if Dark Fiber is a good fit for your organisation, if it is available where you need it and we can help you organise proposals from vendors to save you the legwork.

LED grow lights are relatively new to the cannabis growing scene, but they have become wildly popular over the last few years with their ability to produce great yields while staying cool and using a reasonable amount of electricity.
The final yield depends a lot on strain and grow skill, as well as the quality of the lamp itself, but that’s a good rule of thumb for most models. For example, a 200W LED (200W true power draw, not an “equivalent” wattage) would yield about 100-200 grams on average, or 3.5 to 7 ounces or even higher
Today’s LED models are much better for growing cannabis than the ones available even a few years ago. Many modern lamps are full spectrum or “wideband” spectrum (instead of only red and blue light diodes, which product a bluish purple light and are sometimes called “blurples”). Full spectrum light is easier on the eyes and adding at least some amount of green light to blurples typically results in healthier growth. Other spectrum colors like red, far red, and infrared are important for the budding flowering stage. LED manufacturers have developed specialized lenses to point light directly to the plants and increase penetration, resulting in bigger yields for the same amount of light compared to older models. There are also many different form factors, with everything from the casing to the size of the diodes varying from model to model.
The “spider style” LEDs are set on the “arms” like a spider as opposed to a solid board. One very popular example is the SPYDR line of LED lights from Orsam. But these typically have an extremely high price. The スパイダーLED grow light that Light On Technology Company provide has relatively low cost and the growers get better results and yield than any other type of LED grow light.
「QuantumBoardLED grow light」という名前は、Horticulture Lighting Groupに由来しますが、現在、このスタイルのLEDにこの用語が使用されることもあります。それらは、ボード上の広い領域に分散している比較的低いワット数のダイオードを持っている傾向があります。これらは最近人気が高まっており、使用されるワット数に対して特に良い結果をもたらすようです。そして、それは自家栽培者にとって良い選択です。

Pet preform manufacturers have two pressing needs for blowing equipment. First, the price of plastic raw materials continues to rise, and manufacturers continue to reduce packaging costs to maximize profits. Therefore, it is necessary to use advanced blowing equipment to make lighter weights. Second, due to rapid market changes, manufacturers must be flexible in responding to the shorter life cycle of beverages, which corresponds to the increasingly frequent product update issues in PET bottle production. It takes time to change the mold to a minimum. These two pressing needs have created a big problem for blower equipment suppliers.
Closed loop technology refers to the integration of the process parameters of wire calibration into the process control system of the stretch blow molding machine to form a closed loop of automatic control and automatic adjustment. Intelligent machine control technology is designed to improve the quality assurance system of blow molding machines. Various data, such as bottle wall thickness, can be monitored via the AgrPETWallplus monitoring system. During operation, data deviating from the system rating will be immediately identified and this information will be transmitted to the control system of the preform heating unit of the blow molding machine in a timely manner. The control system will quickly reflect and individually control the heating lamps in the furnace. Rating. Therefore, even if the data of each bottle is different, the quality of the bottle produced is still stable and reliable under the condition that the initial set process parameters of the Pet Bottle Mould remain unchanged.


How does the processor work
All the computing devices that are there today, whether it is simple toys or a business system, they all have one thing in common, that is the Central Processing Unit.
CPU Processor A computer is silent which is equal to the size of a match book. Inside Rakesh there is a silicon rectangle which contains millions of transcrites.
Dozens of metric pins protrude from the device, each of which emits electronic signals from inside the chip.
The chip plugs into a socket on the computer’s circle board and the memory for the CPU, the hard drive, the display screen, the other device communicates with. In today’s article, we’ll talk about the CPU’s processor
What is CPU processor
The CPU performs calculations, performs large comparisons and moves data billions of times every second.
Processor, also called CPU, is a logic secretary that responds to and processes the basic instructions that run a computer. The CPO is seen as the main and most important integrated circuitry IC chip of the computer as it is used to execute most computer commands. is more responsible for
The CPU performs the most basic arithmetic, logical and IO operations, as well as provides commands to other chips and components running in the computer. The processor is often called the CPU itself, but the CPU is not the only process of the computer. GPU stands for Graphics Processing Unit. the greatest example of this
Apart from this, the hard drive and other devices within the computer perform the processing work in different ways. Yet the word processor is usually understood to mean the CPU itself. Processors can be found in PCs, smartphones, tablets and other computers today. The two main competitions in the processor market in India are Inter and A nd
What is the basic elements of processor
Arithmetic Logic Unit (ALU)
ALU is also a circuit in a processor called an arithmetic and logic unit that performs calculations and comparisons. It carries out instructions for numerical and logic operations.
For arithmetic, most CPUs perform basic multiplication addition division and subtraction. Difficult maths such as function files are performed at high speed. ALU also performs logical comparisons between two data items to see if they are equal, whether the first is worth more than the second.
Floating point unit FPU FPU is also known as maths coprocessor and noprocessor. It is a specialized co-processor that can manipulate and solve numbers much faster than contract basic micro-processing circuits.
< jio fi>
Register It stores the instructions and other data. The register supplies the operation to the ALU and stores the results of the operation. 4.L1and L2 cache memory They are used to collect data faster than the dam. What is CPU operation The 4 primary functions of a processor are Fetch decode execute write back
Fetch It is an operation that takes instructions from program memory to RAM
Decode is where the instruction is decoded to find out what other parts of the CPU are needed to continue the operation 3.Execute
This is where the operation performs. In this way every part of the CPU is needed to complete an instruction. What is CPU component and work The main component of a CPU is its ALU register and control unit. You have read all the basic functions of ALU and register, so now you know about the working of control unit.
The control unit is the one that performs instructions and coordinates the activities between the rest of the processor’s functions. instructs to For example, the control unit may instruct the ALU to multiply two numbers together and then add a third to the result.
The processor used in small devices in a personal computer is often called a microprocessor. It happens that the processor elements are present in a single IC chip. Some computers use a multi-core processor for car work, which means a single chip with more than 1 CPU. A CPU is usually a small device mounted on the bottom of the motherboard. cpu processor working process Program instructions and data to be stored in memory from an input device or a secondary storage device Once the required data and instructions are in memory, CPU follows 4 steps for each instruction Collects instructions from CPU memory. CPU decodes instruction and instructs that necessary data should be moved from memory to ALU
ALU solves arithmetic or logic unit instructions
4 ALU result of memory it stores in register How processor is needed for a system to work. How many types of processor? Now most processors are multicore, this means that the IC includes two or more processors. So that the performance can be improved. It reduces the power consumption and is able to do many tasks simultaneously Multicore setup is similar to installing multiple different processors in a single computer but the processors actually stick to the same hobby, the collection between them is faster.
Most computers can have 2 to 4 cores, although this number can increase to 12 cores. If the core is able to process the instructions, then where does it go to the dual core processor? Similarly a 4 core processor would be considered a 4 core processor as many as how many instructions can be given to a computer at once.
Some use multithreading which uses Virchilites processor cores Virchilite processor cores are called vCPU. These are not as powerful as physical calls but can be used to improve performance in Visual Machine. However adding unnecessary vcpus can damage the consolidation rescue so maximum 4 to 6 vcpus with every physical call. We hope that you have liked any article, if you have any question related to this article, then you can comment, we will try our best to answer it.

ML Algorithms – Which one is better ?
In every situation we went through numerous option same as here. Whenever we decided to work on ML, we do stuck into a thought process of selecting an algorithm which suits our need. Its also bit complicated to know all the minor details of each one of them. Then how can we decide X is better then Y ?
So Here is something which can make sense when we have some common agenda of comparing and analyzing these algorithm. I decided to get through regression and classification tasks of ML to write this article.
Requirement for Space
To execute an algorithm we need a space but its not handy if it is loading too much data into the working memory of a machine. i.e. Space constraint is an important factor which should be considered while selecting and algorithm.
Sample of Data and Required sample of Data for training, both are equally important for data analysis and Machine Learning. So its like number of training samples needed for an algorithm to train a model with valid generalization needs to be considered. Like neural network needs more complex data set then a commonly used KN-algorithm. It concludes based upon the complexity of data we can analyze and decide algorithm to work upon.
The two most powerful warriors are time and patienceLeo Tolstoy, War and Peace
Here if we talk about time constraint please do not misunderstood with reference of wall clock time required. Its all about computational complexity. i.e. How an elementary operations is getting handled by an algorithm. It has benefit of deciding on the ground of computer power, architecture and underlying programming language a developer has decided. Here important to note that time constraint can be different for training, validation and prediction. Like with Linear regression you can have more time required while training but validation can be more accurate.
Its mainly about how our algorithm handles tasks. almost similar to dividing a task to different workers at same time to enhance the pace. A parallel algorithm can complete more then one task at the same time. We can divide the workload within a machine only or on different machine using different processors. Sequential algorithm like gradient boost or decision tree is mean to work upon previous errors so its difficult to parallelize in such cases.
Online V/s Offline
Learning basically concern about updating or generating the parameters which can be used to predict some output. Online learning refers to a developing a parameter once a data presented and updating those values once a new set of data arrived. While in case of offline learning algorithm needs a fresh start which included earlier and latest sets of data all together to generate the parameter for predictions. It would be always better to work with online supported algorithm as in real time data can enhance the working of model with parameter updates.
In case of statistical machine learning model or learning we consider parametricity of an algorithm. In simple words if number of parameters developed by an algorithm is fixed even in case of new data elements added it is supposed to be a parametric algorithm based model while non-parametric model will result addition parameters when new data came into the picture. Assumptions of shapes of probability distribution of a data also lets us decide to choose a parametric or non-parametric model.
Bias and Variance trade off
With different ML algorithm we can see different bias variance trade off. Lets make it more clear. Bias means getting aligned towards certain result more as compared to other. Same here a bias error basically denotes model based upon a particular algorithm is biased towards a particular solution more as compared to other. for example if we apply linear regression over non-linear the result will be biased. Next Variance is the error which results because of variances of data sets. We calculate on the ground of average square differences of the prediction made and the expected result of the model
Objectives and Methods used
There is always an objective a Machine Learning model. To fullfill the objective we need to select a method so its very import to compare on the ground of reasons and logic to decide. i.e what are the possible optimization techniques that can be used through algorithm to generate a Machine Learning model. For example with linear regression we optimize the square loss of predicted and actual value while with Lasso regression we minimize MSE while restricting the parameters learned with regularization to overcome overfitting.
On conclusion it can be said an algorithm can be analyzed on different grounds. These process will always results into more better machine learning model for predictions and assumptions

ISE 2012: Sharp outstanding with high brightness and interactivity
From 31 January to 2 February 2012, Integrated Systems Europe (ISE) will again be opening its doors in Amsterdam. Sharp, in addition to its extensive portfolio of professional displays and monitor installations, will for the first time be unveiling the prototype of its new interactive whiteboard, with a diagonal screen size of more than two metres (80 inches). In the field of high brightness displays, the company will also be presenting its new PN-A601 series of outdoor monitors with a brightness of 2000 candelas.
Distinctly bright: Sharp unveils high-brightness displays
Anyone who has struggled in vain to see something on a monitor in sunlight will know that good weather can also be something of a glaring problem. In particular, intense incident light can often make life difficult for operators of digital information systems. With the new high-brightness models PN-A601 and PN-V602, Sharp is now offering displays with a brightness of 2000 or 1500 candelas, able to render content in excellent picture quality and brilliant colours, even in extremely bright environments. The full-array LED backlighting of these displays guarantees optimal picture brightness. Additionally, the local dimming function ensures high contrast and particularly low power consumption.
Large-format touch displays: Sharp presents new interactive whiteboards with up to 80-inch diagonal screen size
From training to brainstorming to business presentation – interactive working is today a proven method for obtaining the best possible results in a minimum of time.

For the past several years I have been pondering what a minimum Crescendo would look like. I began many years ago thinking that, in the interest of highest accuracy, I would use 100 quarter-Bark channels of correction. That may well be accurate, but can a human discern the difference on real music versus a more sawn off implementation?
I did find that using as few as 3-5 bands, in emergencies, provides at least some benefits. But there is no comparison between that emergency grade Crescendo and a much more complex implementation.
So how few bands can we get away with? I found along the way that our hearing shares something in common with our sense of vision. It has been known for some time that our ability to discern spatial variations of color is much less acute than our ability to sense intensity variations. That’s why the Bayer matrix, found in CCD cameras everywhere, works so well for us. The Bayer matrix trades off color spatial resolution against intensity resolution, offering only half the color resolution as the sensor provides.
Our hearing is like that too. We can sense pitch variations of only a few cents (1/100 semitone). But our sense of loudness variation with frequency is much more coarse.
My current implementation uses 11 bands of 2.5 Bark wide channels, spanning the audible range from 20 Hz to about 16 kHz. Not much to be found in music above 15 kHz, and most of us wouldn’t be able to hear it anyway. That’s why perceptual coding of audio cuts off at 15 kHz. If you have sensioneural loss then, for sure, you won’t be able to hear it.
I find that I can barely discern the difference between this 11 band Crescendo and the 100 band version. Music sounds very very good in the little version.
Crescendo works by taking in the digital audio stream and analyzing the power in each analysis channel, independently for left and right audio channels. Then knowing how much power is in each band it can determine the instantaneous nonlinear compression gain to apply to the audio within that Bark channel. It does this about 300 times per second on overlapping chunks of the audio stream.
To estimate the power in each channel we need to use shaped bandpass filters that have some resemblance to what our chochlea offers. The filters I’m now using for power estimation look like this:
Individual filters are shown in green, while their power-sum is shown in red. Notice how they broaden toward higher frequencies. And notice the asymmetry in their response, being steeper on the low frequency skirt, compared to the high frequency skirt.
The skew in these filters occurs because we are taking constant width, skewed, triangular filters from Bark frequency space and mapping them to our conventional Hz space. In Bark frequency space, the filters actually have a steeper roll-off (-20 dB/Bark) on the high frequency side than on the low side (-10 dB/Bark), to match how our cochlear filters behave. That is to say, in Bark space, the filters are actually skewed in the opposite direction to how they appear in linear Hz space. (This point needs reexamination! See below…)
The next graph shows these same filters, now plotted in Log Hz space. That is closer to, but not the same as, Bark frequency. But here you can see that these filters are closer to constant-Q filters, where the frequency-relative shape is nearly constant as frequency rises.
This is one of the major failings of current day hearing aids, which use WOLA filtering – akin to FFT processing. Each channel on a WOLA filtered hearing aid has constant bandwidth, with shape symmetry in Hz space, not Bark space. And so if you have a 16 channel hearing aid, it likely only covers (poorly) from about 500 Hz to 5-6 kHz in symmetric, equal width, Hz channels.
Adding insult to this injury, a musical sound spectrum rolls off toward higher frequencies, which leads to power starvation in narrow constant-width analysis channels. That makes the signal to noise ratio decline, and the highest frequency corrections become increasingly worthless.
Our hearing does not use equal width channels – at least not in our conventional Hz frequency space. It works approximately in Bark-scaled frequency space. And in that space, the channels are approximately equal width. But they are also not in fixed locations in frequency, but rather are self-organizing channels around the loudest spectral peaks in the sound.
And the broadening of the channels toward higher frequencies means that despite the rolloff in the audible spectrum, we are taking in more and more power summing at the highest frequencies. That approximately balances out the decline in spectrum power, keeping the signal to noise ratio approximately constant.
So, with fixed channel assignments, even our Crescendo remains a crude approximation of what would really be needed. But even so, it is a major improvement over anything else, especially of nothing.
[Point to examine: Should we be making our analysis filterbank resemble what the cochlear filter bank is doing?
We aren’t trying to simulate a chochlea. Our chochleae will impose their own filtering on top of what we do in Crescendo. So our job should be to just try to estimate power in each Bark channel. There ought not to be asymmetric rolloff on the filter skirts in Bark space.
If anything, it would seem that we are giving a double shot at upward masking by having our filters shaped like the cochlear filters. The cochlea will do its own upward masking. Or will it? Maybe we need the extra masking help here, to overcome the damaged sensors in our cochlea?
Despite this uncertainty, it sounds very very good. So here again is an indication that our loudness sense is not very acute, compared with our sense of tuning.]

A Brief History of AI
AI is the science and engineering of creating machines and systems that can perform tasks that require human intelligence.
AI was born in 1956 at the Dartmouth Conference, where researchers discussed the possibility of creating machines that can think and act like humans. Some of the early achievements of AI include programs that could prove theorems, solve problems, learn from data, simulate conversations, and understand and manipulate objects.
However, AI faced some challenges and limitations in the mid-1970s to the late 1980s, such as the difficulty of dealing with uncertainty, ambiguity, common sense, scalability, generality, and computational cost. The revival of AI came in the 1990s, with the emergence of new paradigms and methods, such as expert systems, machine learning, evolutionary computation, fuzzy logic, and artificial neural networks.
The most recent and significant breakthrough in AI came in the 2010s, with the advent of deep learning, which uses multiple layers of artificial neural networks to learn from data and perform tasks that are beyond the capabilities of traditional machine learning methods.
The Rise of Deep Learning

When I try to run LuaRT-1.4.0-x64.exe, nothing happens. No install, no error message. I have a 64 bit Windows 10 machine. Under Setings, About, it clearly says "System type 64-bit operating system, x64-based processor". Any idea what the problem is? The 32 bit version installs without any issue.
There was no prior version of LuaRT when I first tried to install 64 bit, so it can't be a conflict with any previous install.


Battery Testing - NFPA 72, 2019
NFPA 72 made some significant changes to battery testing requirements in the 2019 edition. Previous editions of NFPA 72 identified types of tests based on the type of battery being tested. Different requirements applied to lead-acid type, nickel-cadmium type, and sealed lead-acid type (the most common type in modern fire alarm systems).
NFPA 72, 2016 Edition, requirements for sealed lead-acid type batteries included replacement based on manufacturer recommendations, charger test to verify proper charging voltage, discharge test to test load test the battery per manufacturer instructions, and a load voltage test to test battery performance under alarm load conditions. The replacement, charger, and discharge tests were required annually, and the load voltage test semiannually.
In the 2019 Edition of NFPA 72 the battery testing requirements were updated to reflect current industry standards and eliminate batteries not commonly used fire alarm systems. The new testing requirements are intended to ensure that fire alarm batteries provide a reliable source of secondary power by focusing on battery replacement, capacity (load) testing, and alternative test methods.
The first thing you may notice is that NFPA 72 changed the term used to describe the most common battery in modern fire alarm systems to a term used by battery manufacturers and the IEEE: VRLA (valve-regulated lead-acid). VLRA batteries are defined in Chapter 3 as a sealed lead-acid cell with a valve that opens when the internal pressure exceeds a set amount. The most common type of VRLA battery is the AGM (absorbed glass mat), where the electrolyte material is held in fiberglass mats that surround the plates.
Before testing the batteries, NFPA 72 requires that the person conducting the test verify that all system software stored in volatile memory is protected from loss. Depending on the system, this may mean ensure that the system is not in programming mode or operating in any condition where normal system operation has not been restored.
A semiannual temperature test is required upon opening the cabinet door. The test needs to be measured at the negative terminal using an infrared thermometer. Any with a temperature greater than 18 degrees F above ambient must be replaced.
A semiannual charger test is conducted with the battery fully charged and connect to the charger. A voltmeter is used to measure the voltage across the battery, and then verified against the equipment manufacturer’s recommendations. If the voltage is outside the limits, the charger must be adjusted or replaced.
A semiannual cell/unit voltage test is conducted with the battery fully charged and connect to the charger. A voltmeter is used to measure the voltage across each cell/unit of the battery. A battery must be replaced if any cell/unit measures a voltage less than 13.26 volts.
Ohmic testing is conducted during initial installation when the battery is installed to establish a baseline ohmic value, and then semiannually to test performance. For the baseline value, data provided by the manufacturer may also be used.
Ohmic testing is a method of testing battery health by measuring the battery’s internal resistant. Typically, ohmic testing uses one of three techniques: conductance, impedance, or resistance to take the measurements.
Ohmic testing is based on Ohm’s Law, which states the relationship between volts, amperes, and ohms in a circuit. Ohmic testing uses the voltage and current to measure the resistive characteristics of the battery’s cells. As batteries age, they degrade and lose capacity. The degradation causes the internal resistance of the battery to increases, decreasing the battery’s ability to accept and hold a charge.
A key part of ohmic testing is establishing a baseline. Every battery has a unique ohmic “signature”, so ohmic testing upon initial installation provides the most accurate measurement. However, if this information is not available, baseline data from the battery manufacturer may be used. Ideally, the ohmic value is tested at least 72 hours after installation to allow the battery to stabilize.
Semiannual testing is conducted with the battery fully charged and connected to the charger. The battery must be replaced when any cell/unit deviate from the established baseline by 30 or more for conductance and 40% or more for resistance or impedance.
A replacement/load test is required every 3 years. The load test requires load testing the battery per manufacturer’s specifications for a discharge rate for 3 hours or more until the terminal voltage decreases to the end voltage specified by the manufacturer. The test duration is used to calculate the battery capacity based on ambient temperature. The battery must be replaced if the capacity is less than or equal to 80%, or at the next scheduled test if capacity is less than 85%. This test is also permitted to be conducted in lieu of an ohmic test.
NFPA 72, A.18.104.22.168 provides more detailed guidelines for ohmic and replacement/load testing.


ORIGINAL REPORTING: Why They Are Solar Power Players
Solar Power Players: SEPA honorees look beyond the rooftop to manage dynamic grids; Distributed solar is just the first challenge coming to the grid edge. These utilities are tackling what's next.
Herman K. Trabish, September 12, 2016 (Utility Dive)
Editor’s note: The award-winning innovations described here continue to lead the way in the solar industry.
The shift in the solar industry toward the integration of a fuller slate of distributed resources like customer-sited storage, smart inverters, and new grid management software prompted the former Solar Electric Power Alliance to change its name to the Smart Electric Power Alliance (SEPA). That shift was evident in SEPA’s Solar Power Player 2016 awards. The winners show how utilities and industry partners can get beyond policy debates, to solutions that allow solar and other distributed technologies to provide grid services as well as savings to utility customers.
This year’s awards show that both utilities and private providers are also thinking beyond rooftop solar and other forms of distributed generation. Several of the awards are for ways to manage the many distributed energy resources (DER) customers are clamoring for and grid operators can use to strengthen and stabilize their systems. For example, the Hawaiian Electric Companies Dora Nakafuji was the Solar Power Champion for designing a more autonomous way to integrate distributed resources. The Village of Minster, Ohio, Municipal Utility was named Public Power Utility of the year for integrating community solar and grid-scale battery energy storage… click here for more

Developing statistical and machine learning methods based on topological data analysis (TDA) to understand brain disorders
Topological data analysis (TDA) is an umbrella term for a set of computational topology tools tracking multidimensional holes (connected components, cycles, voids etc.) in data objects. It has recently found applications in a wide variety of research areas, such as astronomy, genomics, neuroscience, and road network. Under the TDA-Brain initiative, we are interested in building topological learning methods, i.e. statistical and machine learning tools that utilize the topological structures and features in neuroimaging data depicted by TDA. Our goal is to obtain fresh insight into brain network disorders, such as epilepsy and post-stroke aphasia, with topological learning of multimodal neuroimaging data.
