Now, network coding is the recent generalization of routing in which nodes can generate output data which is produced from encoding or applying certain functions on the previously received input ...

Probability – Introduction

Mathematics, Probability
Book Probability by Jim Pitman, Springer The main concepts of probability theory include: These three concepts form the fundamental framework of probability theory. They describe the structure of any random process, from a simple coin toss to complex risk modeling. Outcome Space (Sample Space) The outcome space (often denoted by the Greek letter Omega, Ω, ...

Linear Algebra – Gaussian Elimination

Linear Algebra, Mathematics
Book: Introduction to Linear Algebra, Johnson et al. Third Edition Gaussian Elimination is a method in linear algebra used to solve systems of linear equations.It systematically transforms a system of equations into a simpler form so the solutions become easy to find. It works by manipulating the augmented matrix of the system using basic row ... Read More

Rank of Matrix

Linear Algebra, Mathematics
The Rank of a Matrix is a fundamental concept in linear algebra that tells you how much “information” or “dimensionality” a matrix preserves. At its core, the rank represents the number of linearly independent rows or columns in a matrix. It is the dimension of the vector space generated by its columns (or rows). https://www.mathsisfun.com/algebra/matrix-rank.html ... Read More

Network Coding

Wireless Communication
https://www.microsoft.com/en-us/research/wp-content/uploads/2007/07/tr-2007-90.pdf In traditional wireless communication, intermediate nodes (routers or relays) act like a postal service: they receive a packet, store it, and then forward it exactly as it was. Network Coding (NC) completely changes this. Instead of just forwarding, nodes are allowed to perform mathematical operations to combine multiple incoming packets into a single outgoing ...

Calculus – Initial Value Problems

Uncategorized
Book Calculus by Thomas/Finney, 9th Edition, Page 282 Understanding Initial Value Problems in Calculus When studying differential equations in calculus, we often encounter something called an Initial Value Problem (IVP). While differential equations describe entire families of functions, an initial value problem helps us find one specific solution that fits a given condition. What Is ... Read More
