2. 1. The Final Size of Multitype Chain-Binomial Epidemic Processes

   Author : Mikael Andersson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; multitype epidemic process; counting process; Markov process; weak convergence; counting process;

   Abstract : A multitype chain-binomial epidemic process is defined for a closed finite population by sampling a simple multidimensional counting process at certain points. The final size of the epidemic is then characterised, given the counting process, as the smallest root of a non-linear system of equations. READ MORE

4. 2. Counting and Tracking : Development and Use of New Methods for Detailed Analysis of Thrombus Formation

   Author : Kjersti Tunströmer; Tomas Lindahl; Lars Faxälv; Nathaniel D Robinson; Judith Cosemans; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Blood platelets are a part of the complex system called haemostasis aimed at ensuring our blood’s continuous transport of oxygen and nutrients throughout the body. The transport is ensured by limiting blood loss due to vessel injury and in this process, the platelets form a plug in the damaged area, reinforced by the formation of fibrin. READ MORE

5. 3. Counting solutions to Diophantine equations

   Author : Oscar Marmon; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Integral points; rational points; counting function; exponential sums; Weyl differencing; van der Corput s method; determinant method; sum of k-th powers; counting function;

   Abstract : This thesis presents various results concerning the density of rational and integral points on algebraic varieties. These results are proven with methods from analytic number theory as well as algebraic geometry. READ MORE

6. 4. Characterisation and application of photon counting X-ray detector systems

   Author : Börje Norlin; Christer Fröjdh; Hans-Erik Nilsson; Sherwood Parker; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monte Carlo simulation; Three-dimensional; X-ray flouriscence; Charge transport; Semiconductor materials; Image sensors; CdTe; Photon counting; Synchrotron radiation; Material recognition; X-ray; Pixel Detector; Silicon; Charge sharing; Imaging; Medipix; Spectroscopy; Dental diagnosis; Image quality; Energy weighting; Electronics; Elektronik;

   Abstract : This thesis concerns the development and characterisation of X-ray imaging systems based on single photon processing. “Colour” X-ray imaging opens up new perspectives within the fields of medical X-ray diagnosis and also in industrial X-ray quality control. READ MORE

7. 5. A statistical approach to multi-input equivalent fatigue loads for the durability of automotive structures

   Author : Gwenaelle Genet; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Equivalent fatigue; uniaxial and multiaxial high cycle fatigue; multi-input variable amplitude loads; rainflow counting; Morel s model; Basquin s model; Gaussian process; Markov chain; Markov chain;

   Abstract : In the automotive industry, due to temporal and financial constraints, we need to strongly reduce the duration of the design phase, but still ensure reliability and robustness. Structures in service are often exposed to complex variable amplitude loads. READ MORE
