1. 1. Asymptotic Expansions of Crossing Rates of Stationary Random Processes

   Författare :Oskar Hagberg; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; Statistik; operationsanalys; aktuariematematik; programming; operations research; Matematik; Statistics; sea elevation; Mathematics; asymptotic expansions; wave crest hight distribution; Saddle point approximations; Crossing rate; programmering;

   Sammanfattning : The crossing rate of a stationary random process is a valuble tool when studying crest hight distributions and maxima of sea level elevation. This thesis considers two approximation techinques for cases when the crossing rate cannot be exactly computed. LÄS MER

3. 2. Molecular Recognition in Antibody Engineering. Studies on recombinant and phage displayed antibodies

   Författare :Ann-Christin Malmborg Hager; Institutionen för immunteknologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; affinity; antibody; kinetic; Immunologi; serologi; serology; Immunology; Bioteknik; Biotechnology; library; selection; surface display; phage display; association rate; dissociation rate;

   Sammanfattning : In vitro generation of antibody fragments of desired specificity and affinity plays an important role since it permits the generation of reagents which may be valuable for diagnostic and therapeutic applications. Furthermore, the kinetic parameters for an antibody-antigen interaction, rather than the affinity, has shown to correlate with biological functions like virus neutralization. LÄS MER

5. 4. Assessment of Aerobic Capacity A Novel Rating Scale and Further Development of an Exercise Test including Analysis of Gas Exchange

   Författare :Anita Wisén; Människan i rörelse: hälsa och rehabilitering; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ; Physical medicine; Time constant of V O2; Cycle ergometer; Perceived Capacity; Perceived exertion; Heart rate; Oxygen uptake; Reference values; Oxygen kinetics; Repeatability; Thresholds;

   Sammanfattning : Different methods are proposed to assess the aerobic capacity. A novel scale, rating of perceived capacity (RPC) based on metabolic equivalents (METs) from 1 to 20, is presented. Selected MET values are linked to physical activities. LÄS MER

7. 5. Large eddy simulation of combustion using linear-eddy subgrid modeling

   Författare :Salman Arshad; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES-LEM; splicing; turbulent combustion; super-grid LES-LEM; CFD; linear eddy model; reaction-rate closure; large eddy simulation;

   Sammanfattning : As emissions regulations are getting stricter and efficiency requirements of internal combustion engines (ICE) are increasing, different concepts to improve combustion are being investigated. For example lean stratified premixed combustion, homogeneous charge compression ignition (HCCI), use of more exhaust gas recirculation (EGR) to reduce NOx etc. LÄS MER
