Training a neural network for different operating points
Hello,
i want to train a neural network to predict the temperature of an electrical machine in different operating points.
I have input data in the form of:
4×1 Cell, each cell with 101×3 elements
So the first cell contains the data for the first operating point, the second for the second…
And Target Data:
4×1 Cell, each cell with 101×1 elements
Where the first cell contains data for the first operating point, the second…
My question is now, which input layer i should use, so that the data is treated correctly ?Hello,

Service Title changing to last attendee booked on
Hi,
We’re currently experiencing some strange behaviour in our scheduled services, whereby the title of the service is automatically updating to the last attendee’s name that booked onto the service.
After further conversations with our users who have independent booking calendars, the same behaviour is being mirrored in each calendar. It’s worth confirming that there have been no changes/configurations made our side, so we’re somewhat unsure if MS has rolled out any product changes that could have impacted or created this error.
Can advise is this is a known issue and what action can be taken to overcome this.

Copilot for Microsoft 365: Datacenter Investments, Customer Spend, and Black Hat Exploits
Market analysts question if companies like Microsoft will ever generate a return on their AI investment. That hasn’t stopped Microsoft spending $19 billion in FY24 Q4, so they must be hopeful. Meanwhile, at Black Hat USA 2024, a presentation exploring some vulnerabilities in Copilot should make all Microsoft 365 tenants with Copilot consider how to secure their organization better.

Help: Highlighting if incorrect value pair in two columns is entered
Hello,
I am very new to power automate, and having some issues to get my head around a problem with conditional formatting or some sort of highlighting a certain condition in my SharePoint list. Maybe someone can help me with the following Szenario or give me some pointers in the right direction.
I have one SharePoint list which is used to track various activities of processes that run on different products.
Column A is of the ‘text’ type and contains a process ID (e.g., ID-111). The column can contain multiple entries of the same process IDColumn B is very similar. It is also of the ‘text’ type and contains the product ID (e.g., P-999). As above the column can contain multiple entries of the same product IDColumn C-… contain various other information, but are irrelevant to the question
What I want is to alert the user via conditional formatting, other forms of highlighting or a dedicated ‘alert’ column if an incorrect ‘process ID <-> product ID’ pair was inserted:
Each process ID is only allowed to have a single product ID associated with it. It is OK to have multiple row entries with the same process ID, but it always has to have the same product ID.
It is also OK to have another process ID associated with the same product ID, but then again the rule above has to apply.
Example:
Process ID // Product ID // Column C // ALERT
ID-111 // P-999 // … // OK
ID-111 // P-999 // … // OK
ID-222 // P-999 // … // OK
ID-222 // P-999 // … // OK
ID-111 // P-888 // … // ERROR
I am quite flexible how the error can be highlighted. It can highlight all rows of the respective process ID or only the newest with the mismatch. Also it does not matter if the product ID field or the process ID field are highlighted or if a dedicated alert column is used.
Previously I have used XLookUp in Excel in combination with help columns to do the trick. But I am somewhat lost at the moment in SharePoint. Some help would be much appreciated 🙂
Please let me know if my explanation was to confusing or if there any open questions:)
Best,
Max

Call to inv() function seems to have (undesired) impact on Thread pool or maxNumCompThreads()
I tried to parallelize parts of my code via parpool("Threads"). I also use maxNumCompThreads to limit the maximum CPU utilization. I use a parfor loop which works as expected, meaning that the defined number of cores corresponds to the total cpu utilization shown in the windows taks manager (more or less).
However, if a call to the inv() function appears somewhere in the code before the thread pool is started, then the cpu utilization of the thread pool is unexpectedly higher, although the number of cores and also maxNumCompThreads is not changed. This happens reproducible, until matlab is restarted (and inv() is not called).
To obtain the unexpected behavior the input to inv() must exceed a certain size: inv(rand(10)) –> nothing happens, but inv(rand(1000)) –> CPU utilization of the following parfor loop is unexpectedly high.
A simple script to reproduce the described behavior (in matlab2023b):
maxNumCompThreads(12);
nCores = 12;
%% random parallel code
fprintf("Before inv function call:n");
pp = parpool("Threads", nCores);
for j = 1:3
tic;
parfor (i = 1:100)
A = rand(1000) / rand(1000);
end
toc
pause(2);
end
delete(pp);
%% matrix inverse
Minv = inv(rand(5000));
pause(5);
%% same random parallel code as before –> CPU Utilization goes up to 100%
fprintf("nnAfter inv function call:n");
pp = parpool("Threads", nCores);
for j = 1:3
tic;
parfor (i = 1:100)
A = rand(1000) / rand(1000);
end
toc
pause(2);
end
delete(pp);
On a 56-core machine, the first parallel block runs with < 20% CPU utilization, while the second block has ~50%.
I get the following output:
Before inv function call:
Starting parallel pool (parpool) using the ‘Threads’ profile …
Connected to parallel pool with 12 workers.
Elapsed time is 5.852217 seconds.
Elapsed time is 2.475874 seconds.

Does the NR HDL Downlink Receiver work on real raw data?
Hi, I have run the Downlink Receiver code with simulations (generated from the 5G Waveform Generator in MATLAB) and there are no issues there, however, when I try to tun the same code through collected raw data, it has never worked before (it says PSS not found). The collected data is confirmed to contain relevant information by other members of my research team, so the problem does not lie with the data itself. Has anyone faced a similar issue?

Temperature increase after increasing flowrate
Hello community,
I am modelling a liquid cooling network which i will parameterize based on a real liquid cooling network that i built.
It consistis of a pump, radiator, reservoir and a cooler element beside the tubing and all additional sensors.
In that particular scenario, the pump is turned on after 10 minutes and reaches it full flowrate after 10 seconds, from there it is constantly working till stop.
The cooler is modelled as a tube element hooked up to a thermal network which is applying 10W of power. The simple tubes before and after should modell the natural convection that i see in the real measurements while powering the heater and keeping the pump turned off.
If the pump is turned on at 600s, we can see a temperatue increase in the sensor located after the cooler which i cannot see in the real measurements and rather looks like the decreasing cooler surface temperature.
I would like to understand how this behavior is created and if possible how to avoid it. I can imagine that at the port of the temperature sensor, after the liquid was heated for that time, that the mass of the liquid inside the cooler is virtually passing the temperature sensor and it taking some time to cool down to average coolant temperature. But as a novice in Simscape Modelling I am having a hard time understanding the mechanisms behind that.
I greatly appreciate any suggestion and explanations from you, looking forward to it. Thanks much!Hello community,
I am modelling a liquid cooling network which i will parameterize based on a real liquid cooling network that i built.

Merging MS 365 Charity Accounts
We have 3 charities that have come together and would like all their e-mails etc under one MS 365 account. Currently they all have their own charity account. Is it possible to merge all 3 accounts into one.
