Error: Out of memory page displayed regullary and I can’t turn off the screen.
I don’t use the Microsoft Edge and I use Chrome.
Everyday Error code: out-of-memory page that hasn’t got any navigation bar displayed and I can’t close it.
It covers my screen so I don’t see other screens and I need to restart again.
It’s really bad for me.
My computer Ram is 32GB and memory is ok when the page displayed.
How can I fix it?

how to create a robot from DH parameters
Hello,
I have the DH matrix of my robot manipulator.
[0.033 -pi/2 0.147 q1;
0.155 0 0 q2-pi/2;
0.135 0 0 q3;
0 pi/2 0 q4+pi/2;
0 0 0.218 q5];
I am trying to create a model of the robot along what’s used here:
https://www.mathworks.com/help/robotics/ref/rigidbodytree.html#d122e13383
the forward kinematics function getTransform() doesn’t return the right Homogeneous transormation matrix, which means the model isn’t correct.

“Failed – Network error”
I have an issue with onedrive where I use the internet version or the application. When i download the files i want, it goes extremely slow (100-700Kb/s). After it has finished downloading all the data it says “Failed – Network error.” After this happens, it crashes my internet connection to my modem and my modem has to reset the connection. When i use any other website or app to download a file there is absolutely no problem and my speed is normal (10-16Mb/s) with no “network error”. I have tried other networks to download from onedrive and have the same exact problem. Super frustrating especially when you want to download files in Gb, wait all that time to have it fail.

Regarding bar graphs for large data
Hey everyone,
I have an issue with the bar graphs x axis data.
I have a large amount of data say for about 1000 iterations and more. It is the load data for every hour of the day along with the number of iterations the load value is being repeated in those 1000 iterations. i.e. the probability of occurrence of the load. But when I create a 2d graph for every hour with load on x axis and occurrence on y axis, the data on y-axis comes exactly, but my load data starts from 1 and ends abruptly without reaching the end value. But the graph shape is correct, I feel the data on the x axis is being given incorrectly according to my research on them for many number of times.I know about the set function but I cannot keep setting the x axis for many iterations as in my case. Did anyone else face this. Can someone guide me through this ?

Monthly to annual totals
Hello,
I am hoping to convert monthly totals to annual totals using a loop. However, instead of using the calendar year (Jan-Dec) I want to use the water year which runs from October to September. I have a number of time series organised in a structure (468 rows, 1 column) starting from Oct 1960 and ending in Sept 1999.
I have attempted to sum up each 12 consecutive rows (1:12, 13:24 and so on) to get the annual totals but my code (below) is not doing the job (I am not sure what exactly it is doing) and I was hoping I could get some help fixing it. Many thanks!
for k=1:length(varnames)
p=0;
for i=1:39
for months=1:12
p=p+1;
annual_flow.(varnames{k})(i,1)=flow_monthly.(varnames{k})(p,1);
end
end

Non linear system by Newton-Raphson
Hey, I m trying to solve a non-linear system by Newton-Raphson method with an iteration max of 10 and 10^(-8) max error.
It ‘s my 1st time using matrices in Matlab and i think i don t get it right because my answer shoul be somewhat around x=0,88 y=0,99
I would love to know what is going wrong in my code ( I hope my derivatives are right (they should be))
thanks !

f2=@(x,y) x.^2+y.^2-2*x;
x1 = 1;
y1 = 1;
P = [x1 ; y1];
F= @(P) [atan(y1)-y1.*x1.^2 ; x1.^2+y1.^2-2*x1];
JF = @(P) [-2.*x1.*y1 (1/(1+y1.^2))-(x1.^(-2)) ; 2.*x1-2 2.*y1];
error = 1;

while k<10 && error > 10^(-8)
Q = P-JF(P)F(P);
error = abs( norm(Q-P)/norm(Q+eps));

get real-time new coming sensor data from mobile phone, old sensor data is not include?
I want to get real-time sensor data using mobile phone,
% Initialize the mobile device object
m = mobiledev;
% Enable the accelerometer sensor
m.AccelerationSensorEnabled = 1;
% Start logging accelerometer data
m.Logging = 1;
% Set the figure for real-time plotting
figure;
duration = 15; % Duration of data collection in seconds
startTime = tic; % Start the timer
% Loop to collect and display data in real-time for 15 seconds
while toc(startTime) < duration
[accelData, timeStamps] = accellog(m); % Retrieve accelerometer data and timestamps
if ~isempty(accelData)
% Plot X, Y, Z axis acceleration in different colors
plot(timeStamps, accelData(:, 1), ‘r’); hold on;
plot(timeStamps, accelData(:, 2), ‘g’);
plot(timeStamps, accelData(:, 3), ‘b’);
xlabel(‘Time (s)’);
ylabel(‘Acceleration (m/s^2)’);
legend(‘X-axis’, ‘Y-axis’, ‘Z-axis’);
drawnow; % Update the plot in real-time
hold off;
end
pause(0.1); % Pause for smooth plotting
end
% Stop logging after the duration
m.Logging = 0;
% Optionally, retrieve all the logged data for further processing
[accelData, timeStamps] = accellog(m);
The function accellog(m) returns all logged accelerometer data from the start of the logging session, including both old and new data, in every call. It does not return only the new sensor data since the last call.
This means that in the code you provided, each time accellog(m) is called inside the loop, it will return the complete set of logged accelerometer data from the moment m.Logging = 1 was set, up to the current time.
How can I get the new coming sensor data? (logging=0 , logging=1 again is not a good way)I want to get real-time sensor data using mobile phone,

Azure maps – embedding iframe
Hi All,
I have a simple map (html) with pin location and is hosted in azure. Is there any way to embed the map using iframe into a web page? I am receiving a “content unavailable” message. I can defintely confirm the map is working and have tried directly using mobile and different networks.
I think the problem is with the embed. Has anyone been successful in embedding using iframe?
Thanks

Retrieving ACR image vulnerability assessment reports in Jenkins
I am currently using Jenkins pipelines to build and test images, during the build stage I upload the newly created image to my Azure Container Registry. In a later stage I want to retrieve the results of the triggered image scan which takes place.
I am currently using az graph query to access the data I need, but that can be quite awkward and groovy doesn’t really like interpreting complex graph queries, is there an easier way to retrieve the vulnerability assessment in a Jenkins pipeline?
