This article written by Luca Zamboni, the author of Getting Started with Simulink describes how solvers are used by Simulink to run the simulation. It explains how every solver perform the simulation by advancing one time step and computing the new outputs starting from the previous state(s) of the system until the end of the simulation time. The initial system state must be fully defined.
The appropriate solver for a model can be chosen by defining these characteristics:
- Time step size, which can be fixed or variable
- Presence of continuous states in the system
- Stiffness of the system

After that we will review how the welcome page is loaded.
By the end of this article, you will know the lifecycle of a request and how to interact with the different components of the framework to produce some output.Read Scratching the Surface of Zend Framework 2 in full
This article by Nishant Neeraj, author of Mastering Apache Cassandra, will describe Cassandra to be distributed, decentralized, fault tolerant, eventually consistent, linearly scalable, and a column-oriented data store. This means Cassandra is made to easily deploy over a cluster of machines located at geographically different places. There is no central master server, so no single point of failure, no bottleneck, data is replicated, and a faulty node can be replaced without any downtime. It's eventually consistent. It is linearly scalable, which means with a greater number of nodes, the requests served per second per node would not go down. Also, the total throughput of the system will increase with each node being added. And finally, it's column oriented, much like a map (or better, a map of sorted maps) or a table with flexible columns where each column is essentially a key-value pair. So, you can add columns as you go, and each row can have a different set of columns (key-value pairs). It does not provide any relational integrity. It is up to the application developer to perform relation management.Read About Cassandra in full
A "state of the art" application sometimes requires more customizations from Devise, such as customization for signing in, updating accounts, or resetting a user's password. When you first install Devise with its default settings, you will not get these features. That's why you will need to dig deeper to have a more comprehensive understanding about Devise, and this article by Hafiz, Nia Mutiara, and Giovanni Sakti, authors of Learning Devise for Rails, will help you do just that.Read Authenticating Your Application with Devise in full
This article written by Sumit Bisht author of the book, Robot Framework Test Automation, explains about management of test structure using Robot Framework. Tests are an important part of software development and through the creation of different tests, one can be assured of the different conditions and use cases that the software can undergo. Typically, there are different forms of testing out of which manual testing is necessary to validate the working of the software before it is useable. This form of testing is known as acceptance testing where the final tests are done on a software under different real world conditions to observe if the software is acceptable by a normal user. Today, this from of testing is increasingly becoming automated and different testing software and tools are present. While the test tools are present for different technologies and uses, their usage increases as the software, and its resultant tests grows.Read Managing Test Structure with Robot Framework in full
