Recommender Systems
Recommender systems are integral parts of our lives now, and they have been for decades already. You might already know it as “the algorithm” and it decides what you see on YouTube or Pinterest or even your JetPack reader. In order for them to be effective, it’s common sense to make sure your algorithm ensures…

Nodes, Kirchhoff’s Current Law and Closed Loops
Starting at an arbitrarily selected node, trace a closed path in a circuit and return to the original node without passing through any intermediate node more than once. The loops, a, b, c, and d are partial of the closed loops in the circuit.

Electrical resistance & conductance
No matter what the references are assigned, the power associated with resistors is always positive, which means resistors are the elements that always absorb energy in circuits.

Thévenin equivalent circuits
The objective of this post is to analyze circuits that can be transformed into simpler Thevenin equivalent circuits. We looked at several types of configurations and worked out the theoretical and simulated results of the Thevenin equivalent circuit, and examined specific points in the circuits including their resistance, current and voltage. As an additional experiment, I’m…

Transient responses of second order RLC circuits
The objective of this experiment is to observe the transient responses of RLC circuits and to learn how R, L, and C affect the circuit behaviors using the ORCAD PSPICE software utility. Specifically second order ones.

Transient responses of first order RL and RC circuits
The objective of this post is to further understand and observe the transient responses of RL and RC circuits. Additionally, another goal of this post is to learn how to measure the time constant of first order circuits using the ORCAD PSPICE software utility.
