1. A Multi-Variate Regression Analysis on Telecommunication Sites in a Sub-Saharan Country
Kandidat-uppsats, KTH/Matematisk statistikSammanfattning : The purpose of this bachelor thesis is to investigate how different variables impact voice and data traffic for a telecom operator that operates in an undisclosed Sub-Saharan African country. The data has been provided by said company. LÄS MER
2. Method development and screening of extractable organofluorine (EOF) and targeted PFAS analysis in food packaging materials
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Per- and polyfluoroalkyl substances (PFAS) have been manufactured and used in differentapplications for several decades, including food packaging materials. During the last 20 yearsthese compounds have been acknowledged as hazardous for humans and the environment, anddifferent regulations on PFAS have been established on both national and international levels.

3. Hydrodynamic Modelling of Spread of Perfluoroalkyl Octanoic Sulphonate and Perfluoroalkyl Hexanoic Sulphonate in Lake Ekoln
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Per and polyfluoroalkyl substances (PFAS) are found ubiquitously in the environment across the globe.These substances have high persistence due to the strong carbon and fluorine bond. In the aquaticenvironment, due to high persistence, these substances don’t decay easily and are detected on the surfaceas well as in groundwater sources. LÄS MER
4. Parameter Update Schemes for Hidden Markov Models applied to Financial Returns
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : This thesis was dedicated to investigating the use of different parameter update schemes for Hidden Markov models with time-varying parameters, with an emphasis on developing alternatives to the quasi-Newton step. The focus was on applications to financial returns, using data from the S\&P-500 and the Nikkei index, and for comparison, a trial using synthetic data was also performed. LÄS MER
5. Security and performance impact of client-side token storage methods
Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för programvaruteknikSammanfattning : Applications store more data than ever before, including sensitive information such as user data, credit card information, and company secrets. Due to the value of this data, malicious actors have a financial incentive to employ a variety of attacks against applications in order to gain access to it. LÄS MER
