Robin-Dirichlet alternating iterative procedure for solving the Cauchy problem for Helmholtz equation in an unbounded domain

Autor: Achieng, Pauline, Berntsson, Fredrik, Kozlov, Vladimir

We consider the Cauchy problem for the Helmholtz equation with a domain in R^d, d>2 with N cylindrical outlets to infinity with bounded inclusions in R^{d-1}. Cauchy data are prescribed on the boundary of the bounded domains and the aim is to find so

Automatiserad laddning avlitiumjonbatterier i mobiltelefoner : En tillämpad studie av hållbarhet ochlivslängdsförlängning för mobiltelefonbatterier

Autor: Lindblad, Ludvig, Berntsson, Fredrik

Sammanfattning Kapaciteten i litiumjonbatterier minskar över tid och användning. Faktorer såsom temperatur,laddningsnivå och djupet av laddningscykeln bidrar till en snabbare degradering. I vissa fall är detomöjligt att kontrollera dessa faktor

Methods of high-dimensional statistical analysis for the prediction and monitoring of engine oil quality

Autor: Berntsson, Fredrik

Engine oils fill important functions in the operation of modern internal combustion engines. Many essential functions are provided by compounds that are either sacrificial or susceptible to degradation. The engine oil will eventually fail to provide

Constructing a Scheduling Algorithm For Multidirectional Elevators

Autor: Edlund, Joakim, Berntsson, Fredrik

With this thesis we aim to create an efficient scheduling algorithm for elevators that can move in multiple directions and establish if and when the algorithm is efficient in comparison to algorithms constructed for traditional elevator algorithms. T

Regression Analysis on NBA Players Background and Performance using Gaussian Processes : Can NBA-drafts be improved by taking socioeconomic background into consideration?

Autor: Persson Lejon, Ludvig, Berntsson, Fredrik

In the modern society it is well known that an individual’s background matters in his career, but should it be taken into consideration in a recruiting process in general and a recruiting process of NBA-players in particular? Previous research show

Schengensamarbetet – Europas dröm

Autor: Berntsson, Fredrik

Denna uppsats klargör vad Schengensamarbetet är för något, varför det finns och hur det fungerar. Uppsatsen går igenom alla delar av samarbetet som till synes största del består av att avskaffa personkontrollerna mellan medlemsländerna.
