Bonsoir

Je me permets de vous contacter afin d’obtenir des informations et un encadrement concernant un projet sur lequel je travaille actuellement. Il s’agit d’une application visant à réguler un oscillateur quantique en potentiel harmonique à l’aide de l’intelligence artificielle.

Plus précisément, mon objectif est de :

Modéliser l’évolution de l’oscillateur quantique sous un potentiel harmonique.

Appliquer des techniques d’IA (réseaux de neurones, renforcement, etc.) pour optimiser la régulation de son état.

Analyser les performances des algorithmes dans le cadre de cette régulation.

Je souhaiterais savoir si vous pourriez m’apporter des conseils ou un encadrement dans la réalisation de ce projet, notamment sur les aspects mathématiques, physiques et computationnels impliqués. De plus, toute suggestion sur des références bibliographiques ou des outils adaptés (MATLAB, Python, TensorFlow, etc.) serait également très précieuse.

Dans l’attente de votre retour, Bien cordialement,

Sara

Hello,
I hope you are doing well. I need your help in developing a Matlab model for the modeling and simulation of the energy and environmental performance of an improved stove (furnace) for the combustion of charcoal briquettes (biochar). I would really appreciate your assistance.
Thank you very much.

C2000 F28379D ADC EPWM

Hi! I am using F28379D DSP. I would like to generate 20khz and 50% duty cycle. I have use ADC with the input 3Vac from voltage sensor. The TBPRD set is 2500 and the CMP value is 1250 with prescaler 1. EPWM1A and EPWM 1B are utilised in this case. Unfortunately EPWM1A duty cycle is shifting/moving/not in phase, EPWM1B is constantly producing 20khz. I am using updown counter. CAU is set CAD is Clear same goes to EPWM1B. Why this happen? I would like to do a switching where PWM 20khz is on during positive half cycle, PWM 20khz is off during negative half cycle. Appreciate for the help!

Did you know there is an official MATLAB certification?

Imagine you are developing a new toolbox for MATLAB. You have a folder full of a few .m files defining a bunch of functions and you are thinking 'This would be useful for others, I'm going to make it available to the world'
What process would you go through? What's the first thing you'd do?
I have my own opinions but don't want to pollute the start of the conversation :)
Hello MATLAB Community,
I'm working on a project where I need to model and simulate a generator or motor system in Simulink, and I want to get the output voltage based on certain design parameters, including the number of turns, magnets, and coils.
I’m looking for a Simulink model or component that would allow me to input:
  • The number of turns in the coils
  • The number of magnets
  • The number of coils
And then, based on this design, output the voltage generated by the system.
I would appreciate any guidance on:
  • Specific Simulink components or models that are suited for this purpose
  • Whether there’s a prebuilt block or if I need to build a custom model
  • Any tips or examples that can help me set up this simulation
Thanks in advance for your help!
Best regards,
Siyabonga

Changing Some MATLAB Plotting Defaults

Over the last 5 years or so, the highest-traffic post on my MATLAB Central image processing blog was not actually about image processing; it was about changing the default line thickness in plots.
Now I have written about some other MATLAB plotting behavior that I have recently changed to suit my own preferences. See this new blog post.
Here is a standard MATLAB plot:
x = 0:pi/100:2*pi;
y1 = sin(x);
y2 = cos(x);
plot(x,y1,x,y2)
I don't like some aspects of this plot, and so I have put the following code into my startup file.
set(groot,"DefaultLineLineWidth",2)
set(groot,"DefaultAxesXLimitMethod","padded")
set(groot,"DefaultAxesYLimitMethod","padded")
set(groot,"DefaultAxesZLimitMethod","padded")
set(groot,"DefaultAxesXGrid","on")
set(groot,"DefaultAxesYGrid","on")
set(groot,"DefaultAxesZGrid","on")
With those defaults changed, here is my preferred appearance:
plot(x,y1,x,y2)
To develop uifigure-based app, I wish MATLAB can provide something like uiquestdlg to replace questdlg without changing too much of the original code developed for figure-based app. Also, uiinputdlg <-> inputdlg and so on.
It is time to support the cameraIntrinsics function to accept a 3-by-3 intrinsic matrix K as an input parameter for constructing the object. Currently, the built-in cameraIntrinsics function can only be constructed by explicitly specifying focalLength, principalPoint, and imageSize. This approach has drawbacks, as it is not very intuitive. In most application scenarios, using the intrinsic matrix
K=[fx,0,cx;
0,fy,cy;
0,0,1]
is much more straightforward and effective!
intrinsics = cameraIntrinsics(K)
Learn the basic of quantum computing, how to simulate quantum circuits on MATLAB and how to run them on real quantum computers using Amazon Braket. There will also be a demonstration of machine learning using quantum computers!
Details at MATLAB-AMAZON Braket Hands-on Quantum Machine Learning Workshop - MATLAB & Simulink. This will be led by MathWorker Hossein Jooya.
I kicked off my own exploration of Quantum Computing in MATLAB a year or so ago and wrote it up on The MATLAB Blog: Quantum computing in MATLAB R2023b: On the desktop and in the cloud » The MATLAB Blog - MATLAB & Simulink. This made use of the MATLAB Support Package for Quantum Computing - File Exchange - MATLAB Central

Wondering where your CPU cycles went? Check AI.

Recently my iMac became sluggish. I checked Activity Monitor and found it was spending most of its time in mds_stores. I turned of Apple Intelligence under System Settings - Apple Intelligence & Siri, and its like new again.

Using DICOM Files as Input for a 3D CNN

I am working on a project with tomosynthesis images of patients with breast cancer, in which I will use 3D CNNs. At the moment, I am selecting the slices where the cancer is visible, and my file format is DICOM. To use 3D CNNs, should I save the selected slices in a new single DICOM file, or should I save each slice in a separate file? What is the best format to use as input for my 3D CNN?
Additionally, to save the selected slices, which DICOM file metadata should I modify? I am modifying only the SOPInstanceUID and the PixelData.

Dark mode power savings vs. human behavior

Do you boast about the energy savings you racking up by using dark mode while stashing your energy bill savings away for an exotic vacation🌴🥥? Well, hold onto your sun hats and flipflops!
A recent study presented at the 1st Internaltional Workshop on Low Carbon Computing suggests that you may be burning more ⚡energy⚡ with your slick dark displays 💻[1].
In a 2x2 factorial design, ten participants viewed a webpage in dark and light modes in both dim and lit settings using an LCD monitor with 16 brightness levels.
  • 80% of participants increased the monitor's brightness in dark mode [2]
  • This occurred in both lit and dim rooms
  • Dark mode did not reduce power draw but increasing monitor brightness did.
The color pixels in an LCD monitor still draw voltage when the screen is black, which is why the monitor looks gray when displaying a pure black background in a dark room. OLED monitors, on the other hand, are capable of turning off pixels that represent pure black and therefore have the potential to save energy with dark mode. A 2021 Purdue study estimates a 3%-9% energy savings with dark mode on OLED monitors using auto-brightness [3]. However, outside of gaming, OLED monitors have a very small market share and still account for less than 25% within the gaming world.
Any MATLAB users out there with OLED monitors? How are you going to spend your mad cash savings when you start using MATLAB's upcoming dark theme?
