Multi-function utility suite

A menu-driven command-line application that brings five tools into one dependable interface: a calculator, Caesar cipher, statistics engine, password generator, and safe exit flow.

Separated features into focused source and header modules
Added resilient type and range validation at every prompt
Applied STL containers, modular arithmetic, and modern random generation

MATLAB Power systems

Transmission network graph model

A power-grid monitoring concept that maps PMU data into a transmission network graph and applies discrete particle swarm optimization to improve topology awareness.

02 / Signal studies

MATLAB notebooks

Focused investigations in system response, frequency behavior, and signal transformation.

01

System response & stability

Compared transfer-function and zero-pole-gain models through impulse, step, Bode, and pole-zero analysis, including settling time, rise time, and overshoot.

02

Frequency response & roll-off

Solved for system gain, plotted Bode magnitude, located −6 dB and −40 dB frequencies, and calculated roll-off in dB per octave.

03

Signals & Fourier transforms

Studied Fourier magnitude, noisy unipolar signals, convolution, power spectra, and weighted average frequency across multiple signal types.
