1. A Machine Learning Approach To Crime Investigation In The New York City Land Area
Magister-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)Sammanfattning : This dissertation will speci cally discuss how machine learning,through some of its algorithms, is able to investigate the various kindsof crime committed in the New York City land area, with special focuson the root-cause, allegedly paving the way for the violation of certainareas of the law. After covering some general background informationconcerning the history of this eld while discussing a few examplestaken from previous work, as well as the history of crime within theinterested geographical area, focus will be placed in rst of all ndingways to retrieve all the necessary numerical information dating backseveral years, since some of them might not be explicitly available,and after ful lling this task, the selected machine learning algorithmswill be implemented to have an insight about the relationship betweenthe chosen variables.

2. An introduction to some ordinary differential equations governing stellar structures
Kandidat-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten)Sammanfattning : The Lane-Emden equation is a non-linear differential equation governing the equilibrium of polytropic stationary self-gravitating, spherically symmetric star models; $${\frac {1}{\xi ^{2}}}{\frac {d}{d\xi }}\left({\xi ^{2}{\frac {d\theta }{d\xi }}}\right)+\theta ^{n}=0.$$ In the isothermal cases we have the Chandrasekhar equation: $${\frac {1}{\xi ^{2}}}{\frac {d}{d\xi }}\left({\xi ^{2}{\frac {d\psi}{d\xi }}}\right)-e^{-\psi}=0$$ After having derived these models, we will go through all cases for which analytic solutions are achievable.
