This repository collects a selection of the main projects developed during my Bachelor’s studies in Physics at the University of Pisa.
It is meant to showcase work completed both individually and in collaboration with peers, across experimental physics, electronics, signal processing, numerical analysis, and scientific computing.
Each PDF corresponds to a laboratory report, technical assignment, or applied project completed during the program.
Experimental project on the lunar halo phenomenon.
Uses image-based circular fitting and geometric optics to estimate the halo radius and infer the refractive index of ice crystals in the atmosphere.
Electronics laboratory report on a common-emitter BJT amplifier.
Studies bias point, current gain, mid-band amplification, phase shift, and frequency response through measurement and comparison with theory.
Experimental analysis of free fall using smartphone video frames.
Reconstructs the height–time law of a falling object and estimates gravitational acceleration through parabolic fitting.
Electronics project on linear circuits with operational amplifiers.
Includes the characterization of a non-inverting amplifier, bandwidth and slew-rate measurements, and the study of a real differentiator.
Electronics project on non-linear circuits with operational amplifiers.
Examines a charge amplifier with shaper and discriminator for time-over-threshold measurements, together with an astable multivibrator.
Thermal physics experiment on the conductivity of aluminum and copper.
Measures temperature profiles along heated bars and estimates thermal conductivity by fitting the stationary heat-flow model.
Introductory laboratory project on density measurements of different solids.
Combines mass and volume measurements, uncertainty propagation, and regression to identify material densities and scaling laws.
Experimental verification of the catenary equation.
Uses a photographed hanging chain, point sampling, and curve fitting to compare the observed shape with the theoretical hyperbolic-cosine model.
Signal-analysis project based on the Fast Fourier Transform.
Studies the spectral content of recorded electronic signals, harmonic structure of waveforms, and resonance behavior in RLC circuits using Python.
Electronics exercise on the current–voltage characteristic of a diode LED.
Fits the measured I–V curve with a Shockley-type model and also includes an estimate of the internal resistance of a multimeter.
Mechanics laboratory project on a quadrifilar pendulum.
Analyzes the decay of velocity, the relation between oscillation amplitude and period, and the agreement between data and the damped-motion model.
Laboratory report on a physical pendulum.
Measures how the oscillation period changes with the distance between the suspension point and the center of mass, validating the theoretical model.
Experimental study of the successive rebounds of an elastic ball.
Uses audio recordings to reconstruct bounce times, infer rebound heights, and estimate the decay factor governing energy loss.
Computational project on Fourier series and Python-based simulation.
Reconstructs periodic signals, discusses the Gibbs phenomenon, and models the response of simple electronic circuits in the frequency domain.
Individual laboratory project for the estimation of gravitational acceleration.
Determines the spring constant of a vertical spring-mass system and then uses Hooke’s law to obtain an experimental estimate of g.
Experimental project on the speed of sound using an ultrasonic sensor.
Measures echo times at different distances, performs a linear fit, and studies the dependence of sound velocity on temperature.
