2. 1. Mobile Satellite Broadcast and Multichannel Communications : analysis and design

   Author : Cristoff Martin; Björn Ottersten; Jack Winters; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; Signal processing; Signalbehandling;

   Abstract : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. READ MORE

7. 5. Multi-platform metabolomics assays to study the responsiveness of the human plasma and lung lavage metabolome

   Author : Masoumeh Karimpour; Malin Nording L.; Magnus Åberg; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LC MS; GC MS; NMR; metabolomics; metabolite; exposure; postprandial; plasma; lung lavage; BW; BW; data analysis; univariate analysis; multivariate analysis;

   Abstract : Metabolomics as a field has been used to track changes and perturbations in the human body by investigating metabolite profiles indicating the change of metabolite levels over time and in response to different challenges. In this thesis work, the main focus was on applying multiplatform-metabolomics to study the human metabolome following exposure to perturbations, such as diet (in the form of a challenge meal) and exhaust emissions (air pollution exposure in a controlled setting).
