Tactical MANETs – Node Mobility, Tx Range, Routing Schemes

MANETs, Wireless CommunicationLeave a Comment

Tactical MANETs Tactical Mobile Ad-Hoc Networks (MANETs) provide dynamic, infrastructure-less connectivity in environments without traditional networks. Live Simulation: Full Network Packet Routing 1. Node Mobility Tactical devices are constantly moving. Military units travel in swarms or platoons, requiring the network to predict group mobility patterns to maintain stable connections as topology shifts. Simulation: Platoon Movement ... Read More

Quantum Feature Map

UncategorizedLeave a Comment

Resources: The Concept: Quantum Feature Maps In classical machine learning, a “kernel trick” is often used to map data into a higher-dimensional space. Quantum computers provide a natural way to do this: Feature Map The process of encoding a classical input vector \( \vec{x} \) into a quantum state \( |\Phi(\vec{x})\rangle \) acts as a ...

Inner or Dot Products – Linear Algebra

UncategorizedLeave a Comment

In linear algebra, the dot product (or inner product) is specifically used for vectors. It takes two vectors of the same dimension and results in a single scalar value (a number). 1. Geometric Definition Geometrically, the dot product measures the overlap or projection of one vector onto another. a · b = ||a|| ||b|| cos(θ) ... Read More

Probability – Conditional Probability and Independence

ProbabilityLeave a Comment

Resource: What is Conditional Probability? Conditional Probability Conditional probability is the likelihood of an event occurring, given that another event has already happened. It allows us to update our understanding of an outcome based on new information or specific “conditions.” The Formula P(A|B) = P(A ∩ B) P(B) • P(A|B): The probability of event A ... Read More

Caculus – Exponential Functions

Calculus, MathematicsLeave a Comment

Resource: The Exponential Function Suppose we have a quantity \(y\), whose rate of change over time is proportional to the amount present. We can describe this relationship using a differential equation: \[ \frac{dy}{dt} = ky \] If we define the initial state where \(y = y_0\) at time \(t = 0\), the solution to this ... Read More
