  1. 1. Extreme Value Analysis of Huge Datasets: Tail Estimation Methods in High-Throughput Screening and Bioinformatics

    Author : Dmitrii Zholud; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extreme Value Statistics; High-Throughput Screening; HTS; Bioinformatics; analysis of huge datasets; quality control; correction of theoretical p-values; comparison of pre-processing methods; SmartTail; estimation of False Discovery Rates; test power; distribution tail; high level excursions; quantile estimation; multiple testing; Student t−test; Welch statistic; small sample sizes; F−test; Wiener process; Gaussian random walk; Shepp statistic; limit theorems; exotic options.; estimation of False Discovery Rates;

    Abstract : This thesis presents results in Extreme Value Theory with applications to High-Throughput Screening and Bioinformatics. The methods described here, however, are applicable to statistical analysis of huge datasets in general. The main results are covered in four papers. READ MORE

  2. 2. Three Essays on Electricity Spot and Financial Derivative Prices at the Nordic Power Exchange

    Author : Daniel Deng; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nord Pool; market efficiency; cointegration; rational expectation competitive storage model; BDS test; Hsiehâ??s third order moment test; nonlinear causality; EGARCH; convenience yield; call option;

    Abstract : Essay I examines the market efficiency issues at the Nord Pool power exchange in the September 1995 - July 2002 period. A unique characteristic of this electricity exchange is the high hydropower proportion in the traded electricity; water in the hydro reservoir acting as hydropower inventory therefore plays an important role in the pricing of electricity.

  3. 3. Lung function in relation to exercise capacity in health and disease

    Author : Amir Farkhooy; Andrei Malinovschi; Christer Janson; Hans Hedenström; Harrpa Arnardottir; Ann Ekberg Jansson; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise capacity; Exercise test; Lung function; Spirometri; Diffusion capacity; COPD; Pulmonary hypertension; Clinical Physiology; Klinisk fysiologi;

    Abstract : Background: Exercise capacity (EC) is widely recognized as a strong and independent predictor of mortality and disease progression in various diseases, including cardiovascular and pulmonary diseases. Furthermore, it is generally accepted that exercise capacity in healthy individuals and in patients suffering from cardiovascular diseases is mainly limited by the maximum cardiac output. READ MORE

  4. 4. On the Application of Surface Wave Surveys for Seismic Site Response Evaluation

    Author : Edwin Obando; Teknisk geologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface wave; MASW; seismic site response; ground motion; seismic transfer functions; shear wave velocity; site amplification; walk-away; near-field effect; dispersion curve.;

    Abstract : In sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. READ MORE

  5. 5. The clinical value of total isovolumic time

    Author : Gani Bajraktari; Michael Henein; Krister Lindmark; Lars-Åke Brodin; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; cardiac resynchronization therapy; predictors; echocardiography; total isovolumic time; six-minute walk test; left ventricular dyssynchrony;

    Abstract : The objective of this thesis is to evaluate the use of Doppler echocardiography markers ofglobal dyssynchrony [total isovolumic time (t-IVT)] in the following 6 studies: 1) Its prognostic role in predicting cardiac events in patients undergoing CABG surgery,compared with conventional global systolic and diastolic measurements. 2) Its additional value in predicting six minute walk test (6-MWT) in patients with leftventricular (LV) ejection fraction (EF) .
