1. 16. Assignment and assessment of orthology and gene function

   Författare :Christian Storm; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Orthology; paralogy; homology; bootstrap; tree reconciliation; Pfam; functional annotation;

   Sammanfattning : Several genomes from different species have been sequenced over the last years, most notably the human genome. An important task of computational biology is to classify and functionally annotate the large amount of sequence data created by the genome sequencing projects. LÄS MER

3. 17. Aspects of Macroeconomic Saving

   Författare :Johan Adler; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Saving; Consumption; Present value model; Capital mobility; Current account; Permanent income hypothesis; Excess sensitivity hypothesis; Tax smoothing hypothesis; Budget policy; Budget deficits; Cointegration; Vector autoregression; Monte Carlo study; Bootstrap;

   Sammanfattning : This thesis deals with various aspects of macroeconomic saving. It consists of an introduction and four self-contained papers. Paper I, "From closed to open door policy: An empirical study of China's international capital mobility, 1958-98," is an empirical application of the open economy permanent income hypothesis (PIH).

4. 18. Filtering and Wavelet Regression Methods with Application to Exercise ECG

   Författare :Stefan Peterson; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aktuariematematik; programmering; operationsanalys; Statistik; actuarial mathematics; programming; operations research; Statistics; Model Selection; Robust Estimation; Haar Wavelets; Wavelets; Time Series Analysis; Exercise ECG; Kalman Filter;

   Sammanfattning : The analysis of the recorded electrical activity of the heart during an exercise test is a valuable method for investigating a patient's circulatory and respiratory system. But the disturbances that occurr during a test often make it difficult to interpret the signal in order to detect changes evoked by the increased workload and related to for instance coronary artery diseases.

5. 19. Partial and General Equilibrium Effects of Unemployment Insurance : Identification, Estimation and Inference

   Författare :Mathias von Buxhoeveden; Björn Öckert; Johan Vikström; Rafael Lalive; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Labor Economics; Unemployment Insurance; Wage Level and Structure; Job Search; Duration Analysis; Econometric and Statistical Methods; Selection Models; Economics; Nationalekonomi;

   Sammanfattning : Essay I: Wage setting models typically posit a tight relationship between the generosity of unemployment insurance (UI) and equilibrium wages. This paper estimates the effect of UI on workers’ wages. LÄS MER

7. 20. Topics in perturbation theory : From IBP identities to integrands

   Författare :Alessandro Georgoudis; Joseph A. Minahan; Tristan McLoughlin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perturbation theory; Feynman Integrals; Integrable field theories; Correlation functions.; Theoretical Physics; Teoretisk fysik;

   Sammanfattning : In this thesis we present different topics in perturbation theory. We start by introducing the method of integration by parts identities, which reduces a generic Feynman integral to a linear combination of a finite basis of master integrals. LÄS MER
