fplot not showing any value
Hello, I’m fairly new to Matlab, and I need to plot a function. This function is the double anti-derivative of another function.
Using fplot to plot the first function works, but it doesn’t show any value for the second function… Here is my code :
syms x D(x) Dint(x) g(x) f(x)
E=2.1*10^11
L=12
F=2000
K=1500
C=0.28
e=0.008
a=0.00076
P=3000
w=77008.5
% Fonctions
D(x)=0.2191-a*x
Dint(x)=D(x)-2*e
f(x)= (-F*(L-x)-K*C*(D(x))*(L-x)^2/2)/(E*3.14*(D(x)^4-Dint(x)^4)/64)
g(x)=int(f(x)) – subs(int(f(x)),x,0)
Y(x)=int(g(x)) – subs(int(g(x)),x,0)

Neural network for regression task: Circuit modeling
Hi everyone, i’m experimenting with using a DNN for modeling an electrical circuit. I have done many tries and until now i always used one sample for input( sequenceInputLayer(1) ) a one for output( since it is a regression task). Now, since the circuit i am modeling has memory, i would like to try to extend input lenght to count for more input sample at once but keeping my output as one single sample. I am facing problems in this beacuse i have my input_data vector that is 1167×1 so 1 column. This means that sequenceInputLayer expect always 1 as dimension and i am limited to this.
On the other hand i can transpose my vectors and use 1167 as input and output dimension, but I would like more freedom and try for example a NN with an input layer of size 300, then 2 hidden layes with size 50/100 (using tanh ecc..) and then my final output layer with output size 1 ( again, since this is a regression task). I already read MATLAB documentstion but i didn’t find what i am searching for. This is the code i am using now, if you have suggestions i would be really happy!!!
Maybe i have to use mini batches? What changes i have to do in order to realize the network i said before?
(Yes, i know that for dynamical systems with memory CNN and RNN neural nets are better but in literature there are also papaer that use DNN for this type of modeling, i.e. using more input(past sample) in a DNN for taking into account memory effects).

This article is to inform you of some important changes that we are making as part of our ongoing efforts to improve your Azure experience and increase pricing transparency. We are making changes to the billing meters that could affect some Azure services and resources that you may use, and we want to make sure you understand what the changes are, why we are doing them, and how they will impact your billing.
These updates will not impact your prices, but you may notice some changes in how your Azure consumption is shown on your invoice, price sheet, API, and other Cost Management tools.

Title: Enhancing Azure Connectivity: Sharing PaaS instance across customer tenants on Azure

Publication Date: 4/28/24
Content excerpt:
I’ve come across a scenario where one of my customer using Azure SQL DB wanted to share their Database with other customer who was also hosted on Azure. They were struggling to establish site-to-site connectivity so that Customer B could access Customer A’s network, enabling them to connect to the Azure SQL DB via the site-to-site tunnel. Though this can be achieved, there are better ways to connect to Azure SQL DB, or any PaaS instance for that matter, with another customer who is using Azure. This can also be used by customers who have multiple Azure AD tenants.

Title: Controlling AKS egress using an HTTP Proxy
Source: Core Infrastructure and Security
Author: Houssem Dellai
Publication Date: 4/22/24
Content excerpt:
Azure Kubernetes Service (AKS) clusters, whether deployed into a managed or custom virtual network, have certain outbound dependencies necessary to function properly. Previously, in environments requiring internet access to be routed through HTTP proxies, this was a problem. Nodes had no way of bootstrapping the configuration, environment variables, and certificates necessary to access internet services.
This feature adds HTTP proxy support to AKS clusters, exposing a straightforward interface that cluster operators can use to secure AKS-required network traffic in proxy-dependent environments.
Both AKS nodes and Pods will be configured to use the HTTP proxy. Here is an architecture diagram showing the different components.

But then, a beacon of hope emerged: the realization that all bank product information is accessible through a common API. With this revelation, I set out to craft my own solution – a personalized Copilot to guide me through the sea of credit card offerings.
Title: Cost allocation is imperative for cloud resource optimization

Author: Antonio Ortoll
Publication Date: 4/15/24
Content excerpt:
Like most enterprises, you are probably managing your Azure resources and services centrally and need a way to distribute and “showback” or reallocate the cost of services back to the organizational units that use those services.
Sharing cloud services provides greater flexibility and scalability when they can be dynamically allocated. But as your cloud adoption grows, the quantity of billing and usage data and the speed at which it is delivered can make allocation and reporting a challenge without a strategy and a system to efficiently assign the costs of cloud resources to their specific users.

We’ve since made substantial progress closing remaining parity gaps in Microsoft Graph PowerShell SDK, and as of March 30, 2024, these PowerShell modules are now deprecated:
Azure AD PowerShell (AzureAD)
Azure AD PowerShell Preview (AzureADPreview)

Title: Onboard to Azure Arc with Security in Mind

Author: Simone Oor
Publication Date: 4/17/24
Content excerpt:
Azure Arc allows certain on-premises resources, typically servers, to be managed from Azure, depending on the configuration mode selected and currently available features.
While this allows for a more integrated approach to hybrid environments, it also further blurs the administrative boundary between on-premises and cloud.
This increases the risk that a vulnerability on either side lowers the level of security across the entire plane. This article contains tips for managing this risk and approaching Arc Onboarding with security in mind.

Matching Content explorer exports in content search – Exchange
Hi
I have been tasked with finding all cardholder data in our tenant.
For SPO and onedrive I can search directly from content search (or ediscovery search)
This is useful because we can export items for further investigation, and most importantly, at some point I will be asked to purge some results.
I have managed to export the content explorer data for exchange using Export-ContentExplorerData powershell.
The resulting csv however isnt very useful in tems of matching items in Exchange.
The only 2 vaguely usefel fields are FileUrl, and FileName
FileName contains contextual data sometimes several lines long, and contonaong characters that screw up a KQL keyword search, and returns too many results.
The FileURL property seems to be a unique ID, but I cant seem to find this property anywhere else, especially in content search.
Has anyone else faced a simliar situation?
