The Sum of the Reciprocals of the Squares
The Sum of the Reciprocals of the Squares
A reproduction of a proof by Leonard Euler, which I dug out of the back of a calculus textbook with the help of Brian Burrell. This was in MATH 233 at the University of Massachusetts, Amherst, Fall 2015.

A Statistical Analysis of the Simpson College Football Offense
A Statistical Analysis of the Simpson College Football Offense
This project explores the predictability of play-calling of the Simpson College football offense during the years of 2012-2014. The models used to assess the predictability include simple analysis as well as linear and logistic regression.

Modeling spatial inhomogeneities in solar cells (MSc Thesis)
Modeling spatial inhomogeneities in solar cells (MSc Thesis)
Microscopic spatial defects (inhomogeneities) in solar cells have a detrimental impact on the overall performance of the solar cells. These defects can be due to the polycrystalline nature of the photovoltaic absorber (general case) or on the other hand, the characterization method itself can induce such inhomogeneities (ex: local excitation with confocal system). Photoluminescence imaging in particular is the most attractive type of experimental character- ization technique which has been studied by many research groups. Since it is contactless, it allows a complete analysis of the photovoltaic material and it can actually be performed at each step of the solar cell fabrication process. To properly analyze the recorded images, one has to model the transport properties. In this work we model the transport properties in 2D using both a numerical and analytic approach. First,we model the global illumination of the sample, we then analyze the effects of grains and surface recombination. Second, we study lateral transport that can be influenced by recombination at the surface (passivation issues), grain boundaries (polycrystalline cells) or local artifacts (shunts, defects...). At the same time we are able to extract the lifetime knowing the generation rate and solving the excess carrier density from our model. And finally we implement our model to extract some cell parameters like the diffusion length from experimental data through data fitting.

Drie technieken voor visuele cryptografie
Drie technieken voor visuele cryptografie
cryptografische systemen zijn gebaseerd op stellingen uit de getaltheorie. Versleuteling en ontsleutelingen van berichten vragen vaak intensief computerrekenwerk. Bij visuele cryptografie wordt het rekenwerk echter tot een minimum beperkt. Ook hoeft de ontwerper van deze geheimcodes bijna geen gebruik te maken van wiskundige stellingen en eigenschappen. De ontsleuteling van een boodschap kan zelfs gebeuren zonder digitale hulpmiddelen: schuif twee transparanten met onherkenbare afbeeldingen over elkaar en kijk doorheen deze transparanten naar de ontsleutelde boodschap. In dit verslag worden drie technieken voor visuele cryptografie toegellicht. Voor de eerste techniek is er wel wat wiskundige achtergrondkennis nodig. De tweede en derde techniek zijn vlot uitvoerbaar zonder deze achtergrond.
