1. 1. An Introduction to p-adic Analytic Groups

   University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Author : Frieder Selisko; [2023]
   Keywords : Mathematics and Statistics;

   Abstract : In this thesis we introduce the concept of a p-adic analytic pro-p group. To do so we discuss important theorems and concepts connected to more general types of groups, these include profinite groups, pro-p groups, powerful p-groups, powerful pro-p groups and uniform groups...

3. 2. Strain-induced nonlinear Hall effect in graphene systems

   University essay from Stockholms universitet/Fysikum

   Author : Pedram Pakmehr; [2022]
   Keywords : ;

   Abstract : This thesis aims to study the nonlinear electrical transport response of monolayer and bilayer graphene systems under the influence of different lattice deformations (strain). Broken inversion and rotation symmetries can generate a second-order transverse current response called the nonlinear Hall effect in the presence of time-reversal symmetry. READ MORE

4. 3. Neural Network Gaze Tracking using Web Camera

   University essay from Medicinsk informatik; Tekniska högskolan

   Author : David Bäck; [2006]
   Keywords : gaze tracking; computer vision; image processing; face detection; rotational symmetries; neural network; backpropagation;

   Abstract : Gaze tracking means to detect and follow the direction in which a person looks. This can be used in for instance human-computer interaction. Most existing systems illuminate the eye with IR-light, possibly damaging the eye. The motivation of this thesis is to develop a truly non-intrusive gaze tracking system, using only a digital camera, e. READ MORE
