Hardware - Science topic

Dear Sir,

I studied your research background and requirements. I have experience of writing research publications and I have published a journal paper with detailed design and development based on verilog programming and FPGA. I also design and develop electrical power and electronic circuits and systems. So, we can collaborate in research.

Regards

First things, clean hardware regularly (such as dust). Keep drivers updated, ensure proper cooling, upgrade RAM/SSD, cautiously overclock, , use a reliable power supply, optimize storage, adjust BIOS settings, disable unnecessary background services, and monitor system performance with tools.

Dear Yashar Salami ,

Machine Learning (ML) tasks are diverse, and so is the hardware on which they can be computed. To better understand how to speed up the calculations, it is important to know what kind of calculations are performed. Calculations used by ML algorithms are largely vector and matrix calculations. For this reason, a suitable computational accelerator for ML applications must be able to perform these calculations.

Hello Mohammed Afnan ,

Let me see if I can paraphrase your question. You are being asked to analyze 'something' using only software or a software-based simulator. The 'something' needs to be either an IOT device or system, or a piece of stand alone hardware, but in either case no hardware implementation is to be attempted. For example, in the case of a piece of stand alone hardware, you would only have a schematic circuit diagram but no actual hardware, and you would simulate this hardware with, say, SPICE. Do I understand your question, correctly?

Hey there Nowsheen Khan!

Implementing a wind energy system in your hardware prototype sounds like an exciting project! To get started, you'll want to consider a few key factors.

Firstly, determining the scale of your wind energy system will help guide your design choices. Are you Nowsheen Khan aiming for a small-scale demonstration or something larger? This will impact the components you'll need and the complexity of your setup.

Next, consider the location and environmental conditions where your prototype will be tested. Understanding the average wind speeds and patterns will help optimize the efficiency of your system.

Regarding the use of a wind emulator, it depends on your specific requirements. While emulators can be useful for testing and validation, they may not always be necessary, especially if you Nowsheen Khan have access to real-world wind conditions for testing.

If you Nowsheen Khan do decide to use a wind emulator, ensure it accurately replicates the conditions your system will encounter. This will help validate your prototype's performance under various scenarios.

Remember, thorough planning and testing will be key to the success of your wind energy system implementation. Feel free to ask if you Nowsheen Khan need further guidance along the way!

To accurately determine the reason for the yellow light and ensure the proper functioning of your NanoDrop 8000, I recommend consulting the instrument's user manual or contacting the manufacturer's technical support for assistance. They can provide specific guidance based on the instrument's design and any error codes or messages displayed.

I believe these are both free. I have used JWatcher in the past and thought it was great, but that was over a decade ago and someone recently recommended Boris to me.

Sure, I can help you with the Simulink model for Hardware in Loop (HIL) for BLDC and induction motor test benches. Here are some general guidelines and considerations:

Additionally, consider the following specific aspects of BLDC and induction motor HIL testing:

Remember that safety is paramount when working with hardware-in-the-loop systems. Always follow proper safety procedures and ensure that the test environment is secure and controlled.

Thanks Shukur!

Here are some strategies to address PC resource limitations:

Hello friends, we tried everything, we called for the technical service from the Cytiva representative here in my country. There was no way to fix it, the box was not communicating with computer. We bought the CU-950 again

1. Turn off both the AKTA Pure and the F9-C fraction collector.

2. Locate the communication cable that came with the F9-C fraction collector. The cable will have a DB-9 connector on one end and an RJ-45 connector on the other end.

3. Connect the DB-9 connector of the communication cable to the RS-232 port on the back of the F9-C fraction collector.

4. Connect the RJ-45 connector of the communication cable to the RS-232 port on the back of the AKTA Pure system.

5. Turn on the F9-C fraction collector, and then turn on the AKTA Pure system.

6. Once both systems are powered on, navigate to the "System Configuration" menu on the AKTA Pure system.

7. Select "Hardware Configuration" and then choose "F9-C Fraction Collector" from the drop-down menu.

8. Enter the appropriate communication settings for the F9-C fraction collector, such as the baud rate, data bits, stop bits, and parity. These settings can usually be found in the F9-C fraction collector user manual.

9. Save the changes, and then exit the menu.

10. You should now be able to control the F9-C fraction collector from the AKTA Pure system. To test the connection, try running a sample purification and verify that the fractions are being collected correctly by the F9-C fraction collector.

There are a number of hardware platforms that can be used for executing EV-related simulations. Here are a few options:

1. Typhoon HIL: Typhoon HIL offers a range of real-time hardware-in-the-loop simulation platforms that can be used for EV-related simulations. Their platforms are designed to provide high-fidelity, real-time simulation of power electronics and control systems.

2. National Instruments: National Instruments offers a range of hardware platforms, including the CompactRIO and the PXI, that can be used for real-time simulation and control of EV-related systems. Their platforms can be programmed using LabVIEW or other programming languages.

3. MathWorks: MathWorks offers a range of hardware platforms that can be used for real-time simulation and testing of control systems, including EV-related systems. These platforms include the xPC Target and the Simulink Real-Time.

4. Vector: Vector offers a range of hardware platforms for real-time simulation and testing of automotive and transportation systems, including EV-related systems. Their platforms include the CANoe and CANalyzer software tools.

5. ETAS: ETAS offers a range of hardware platforms for real-time simulation and testing of automotive and transportation systems, including EV-related systems. Their platforms include the LABCAR and the INCA software tools.

It's important to note that the choice of hardware platform will depend on the specific requirements of your EV-related simulation. Consider factors such as the complexity of the system, the level of fidelity required, and the available budget when selecting a hardware platform.

Thanks a lot. answers and feedback gave me confidence that I am working in the correct direction.

See the properties of Diode SCHOTTKY.

Modeling software such as CAD, CAE, and CAM is widely used in simulation and other animation processes. Higher specifications for the processor, RAM, and graphic processor are needed for this software. There are other programs like Flow-3D Cast and Novacast Software that are built for particular procedures.

How can we incorporate MAC/PHY impairments in NetSim when connecting a Raspberry PI (controller) and sensor to NetSim?

I need more information on the way the device is connected. Is the Analog to Digital conversion being done in the Device (Spec.) and only results communicated to the computer, or is the communication being done over one of the "standard" interfaces like HDMI or any PD (thru PD++)or just Ethernet, but with the conversions being done within the computer. There are 2 basic questions: 1) where are the control function decisions being made 2)how are the communications being managed. The difference is how much the vendor is using commercial off the shelf (COTS) components with industry standard interface definitions, and how much is a custom proprietary implementation?

You would need to know these details of the interface to diagnose the issues you described.

My recommendations are:

(i) MATLAB (https://www.mathworks.com/products/5g.html)

(ii) NetSim (https://tetcos.com/5g.html)

Dear Petar D. Bojović

Your question reminded me of a comparison between different components of the mind, regarded as hardware and software. Hambrick and Engle (2002) mention that working memory capacity and other aspects of the cognitive system are the mind's hardware due to their relatively stable nature. On the other hand, domain knowledge would be a more flexible aspect. Hence, it would be considered the software.

Cheers,

Aparna Sathya Murthy mam i would like to work in image processing . if you please give some suggetion

Looks like the baseline wasn't set correctly. Check the settings to make sure that someone didn't change the default settings.

And very is "below image"?

For this we need to do Vedic maths smoothly and properly. we need proper comparative study.

I would also go for a Microsensor. Unisense has sensors in a hypodermic needle which are rather robust do that you can push them into the sediment. Taking a small subsample always bears the risk of getting it oxidized and thus too low pH readings

It looks like a problem in the geometry of your system. If you don't notice anything unusual on visual inspection, you can try to rebuild your system or perform a double-precision minimization.

If you are interested in developing hardware that will help to increase the huge number of transactions at low cost, such as; Application Specific Integrated Circuit, Smart Network Interface Card and FPGA.

These research papers include some information that you are looking for

Hi Abigail

After you did and if you fallow the above suggestion, if you still have the same issue, I am guessing the auto sampling probe contaminated your standards/blanks due too some kind of failure - obvious, If you have an auto-sampling...

Good luck

Yes, it seems like that. Try here:

A bit overkill. And be aware that you need a 12 volt supply as well (easily diverted from the server). How about the random switching on boot up? No risk to trigger a false alarm.

How about: https://www.aliexpress.com/item/1005001993993906.html?spm=a2g0o.productlist.0.0.55951253x2ArhO&algo_pvid=1c78d902-9808-47b9-a0e9-58b81a0581b0&algo_exp_id=1c78d902-9808-47b9-a0e9-58b81a0581b0-1&pdp_ext_f=%7B%22sku_id%22%3A%2212000018348604377%22%7D&pdp_npi=2%40dis%21CHF%21%212.04%21%21%21%21%21%400b0a556f16522818039484735e6c60%2112000018348604377%21sea

Computer Aided tools like LTSpice, PSpice, OrCAD etc., are available , but check this link which can help you in which they provided a Matlab Package for FPGA (Hardware ) implementation

Elementary articles do have relevance if published in refereed and indexed journals.

Abaqus Standard tends to have benefit of number of cores start to level off significantly after 16 cores. More is always better though for larger problems. Using the MP_HOST_SPLIT parameter and setting it to an integer that can be evenly divided into the number of cores or sockets will help immensely, more so than even GPU computing. GPU computing can help in larger problems, but you need number of GPUs installed in a machine equal to MP_HOST_SPLIT parameter. If MP_HOST_SPLIT = 1 you'll get poor performance, and a single GPU can help a lot then. But with MP_HOST_SPLIT set to the proper number (say 2 or 4 for 16 cores) you'll get a good speed up, better than an single GPU and MP_HOST_SPLIT=1. All the hype on GPU computing is totally overblown, believe me I know. I have 3 GPUs installed and I still don't get much improvement, if at all. Spent many an hour with the Abaqus people on this. You do well with MP_HOST_SPLIT = 1 and GPU, but just set MP_HOST_SPLIT equal to the proper number and you'll do better with no GPU. Did I mention they don't support or document this much? Silly. For Abaqus Explicit, that is a different animal, and more cores is always much better for larger problems.

Good luck,

Steve

If you are not afraid of speed (!), using Amber of charmm FF, you can use ACEMD (performance are described here: https://software.acellera.com/docs/latest/acemd/performance.html)

Hello, Ujwal. I hope everything is going well for you. I'd like to share a DOT-related link with you. You can find several helpful pdf files at this link. I hope I was able to assist you.

probably it will increase delay

I have talked recently with a colleague about free Open Source electronic lab notebook for chemists. She gave me the following hints:

eLabTFW (https://www.elabftw.net/)

Maybe this helps anyone who looks for electronic lab notebook software.

Dear Andrey Viborniy ,

You can use ultrasound transducers to measure the distance between the adjacent cars. You send a pulse and receive it after back bouncing from the adjacent car. The time delay between the two pulses is equal double the distance between the two cars. If the distance is smaller than a critical distance then alarm will be launched.

For more details about the building of the system please follow the paper in the link:

You may find similar papers by searching the web.

Best wishes

As already suggested I would use R that does not only offer several mapping options but a large suite of statistical packages. Keep in mind that if coding and programming is not exactly your thing and you need something more user-friendly, you could use the free Quantum GIS software which can be interfaced to a series of other applications, including R scripts, GRASS and many more to run propertary algorithms throug a GUI user-friendly interface

This may not be a hardware issue. Please check you cost function or model and its codes carefully. Also check the sizes of your matrices and the singularities, sparseness of your matrices. I hope by rechecking your theory & codes, you will solve your problem easily.

maybe we can discuss this privately :my e-mail

in any case there are several standard methods of doing this..(like Malcolm indicated already) and it all depends on your particular parameters

Have you contacted Horiba? In Piscataway, New Jersey? That is where all the Raman experts are located and I am sure that they will answer your questions. The phone numbers are on the website as well as the email addresses.

Maybe this will be useful for you: https://forum.arduino.cc/t/pwm-signal-5v-to-control-10v-pwm/586102

The answer depends on the purpose Blockchain (BC) applying for. For crypto there are some wallets now available in the market, i.e., https://www.ledger.com/. However if BC is used for IoT purpose, then there are some emerging applications can be seen here..https://builtin.com/blockchain/blockchain-iot-examples. Appreciated the quesion.

Have you tried Apmonitor examples? http://apmonitor.com/wiki/index.php/Main/Control

I have their unit but been busy and haven gotten through to the MPC example, but they provide excellent documentation for Matlab and Python examples. Here is also a video https://www.youtube.com/watch?v=nqv6jFeVUYA&list=PLLBUgWXdTBDhrs5FuoJXni-cIeNYEyxw1&index=23&ab_channel=APMonitor.com

You should use OPEN GL for the AMD graphics card. I'm not sure AMD supports Abaqus parallel computing.

Agree with Qamar Ul Islam.

Farzad Tat Shahdost I did an implementation on robots a while ago. Please see

what’s about of example r317 or r3_17 or r31_7

Well, it's depended how you are doing SAR Data processing.

if you are using Sofware like SNAP, you need a powerful processing computer.

As of now Google Earth Engine is suitable alternative if you have programming command.

Number of images required is totally depends on what you are doping through SAR data

Ask the following questions - how much memory does your code need, how much data memory is needed, what is the required CPU speed, do you need any special interfaces?

One thing you will need to do is verify that the HPLC and fraction collector are "aligned". Some HPLC systems specify tubing lengths from the detector(s) and fraction collector, suggesting their software compensates for the delay time. This link (https://www.waters.com/webassets/cms/support/docs/71500012102re.pdf ) page 86, makes reference to a delaying time (I realize this is for a different fraction collector than yours, but the concept still holds).

I think you can choose the peaks for collection from a prior run.

Hi Eric,

I no longer work at Horiba and am not familiar with the latest software. I was going to forward this to my former colleague, but it's probably best/faster if you just call their help desk. Someone can answer this for you in a couple minutes.

Since the mapping enforces a one-to-one correspondence between the original set with a gaussian distribution and the new one with a uniform distribution, any correlation in the former must be traceable in the latter as well.

As for how to qualitatively measure it, let's say you generate N numbers with a gaussian distribution, x_G, you then map these numbers into their corresponding set with a uniform probability distribution, x_u, using the cumulative distribution function:

x_u=0.5(1+erf(x_G/sqrt(2))

Mind that here I assume your Gaussian probability distribution has sigma=1 and is clustered around x=x0=0. If this is not the case, you should use the general expression:

x_u=0.5(1+erf( (x_G-x0) / (sigma*sqrt(2)) )

Once you've got the uniformly distributed set x_u, you can then check its randomness using any standard toolkit like NIST test suite.

We did not patch it, indeed. We still use that previous version of Windows 10 (1607) when needed.

Dear Waqas,

Please see the attachment.

I hope this solution is useful.

Hi Firdaus

This article is helpful to answer your question.

Kind Regards!

Arfan Arshad

It is absolutely feasible. I presume you want to solve a set of linear equations, so I would go for an LU factorization scheme. These rely on row/column operations that can be readily implemented in FPGAs. I suggest familiarizing yourself with matrix factorization algorithms and then thinking about how to transfer the factorization scheme into an FPGA. Since this sounds like a class project, I can't give you the solution! ;-)

Just proves Schrodinger's law.....

Dear Raivo, I was also thinking of Janez Seliger...I think he has retired but he is here on RG - I'll get in contact with him directly!

Thanks anyways..

Alfred

It depends on your problem as well as the resource constrained device you're using. From your question, what I get is that you're more interested to know about some alternative better solutions for convolutions, that can be Atrous convolutions which may take much time during training, but inferencing will be comparatively efficient. Further, you can also go for pruning strategies and please have a look at the concept explained in recent ESPNet convolutions.
