2. 1. Ultrasound Examination in Infant Clubfoot with Special Emphasis on the Talonavicular and the Calcaneocuboid Joints

   Author : Ylva Aurell; Lund Diagnostisk radiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; tomography; medical instrumentation; ultrasonography; Clinical physics; radiology; infant; foot deformities- congenital; anatomy; clubfoot;

   Abstract : The purpose of the study was to develop an ultrasound (US) protocol for evaluating congenital clubfoot pathoanatomy before and during early treatment. By using 3 easily defined and reproducible US projections the talonavicular and the calcaneocuboid joints were assessed. READ MORE

   Author : Alexander Aurell; Boualem Djehiche; Xiaoming Hu; Roland Malhamé; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pedestrian crowds; stochastic differential equations; mean field; stochastic control; games; backward dynamics; sticky boundary; stochastic maximum principle; social conventions; folkmassor; stokastiska differentialekvationer; medelfält; stokastisk styrning; limaktiga randvillkor; stokastiska maximumprincipen; dynamik med ändvillkor; spel; konventioner;

   Abstract : This thesis consists of five appended papers, primarily addressingtopics in pedestrian crowd modeling and the formation of conventions.The first paper generalizes a pedestrian crowd model for competingsubcrowds to include nonlocal interactions and an arbitrary (butfinite) number of subcrowds.

5. 3. Effects of Varying Combustion Conditions on PCDD/F Formation

   Author : Johanna Aurell; Stellan Marklund; Sukh Sidhu; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; dioxin; formation; PCDD; PCDF; MSW incineration; transient combustion; sulfur; memory effects; quench time; chlorine; combustion; polychlorinated dibenzothiophenes; NO; water; Environmental chemistry; Miljökemi;

   Abstract : Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. READ MORE

6. 4. Statistical models of TF/DNA interaction

   Author : Aymeric Fouquier d'Herouel; Erik Aurell; Otto Berg; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gene expression; regulation; transcription factor; binding motif; matrix representations; gibbs sampling; binding affinity; non-specific binding; Biological physics; Biologisk fysik;

   Abstract : Gene expression is regulated in response to metabolic necessities and environmental changes throughout the life of a cell. A major part of this regulation is governed at the level of transcription, deciding whether messengers to specific genes are produced or not. READ MORE

7. 5. On state space structure and average case complexity in random K-SAT problems

   Author : John Ardelius; Erik Aurell; Bart Selman; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Abstract : This thesis gives an introduction to a currently active area in the cross-section between theoretical computer science and theoretical physics. In the last ten years it has been suggested that critical behaviour, usually seen in models from condensed matter physics, may be responsible for the intractability of NP complete computation problems.
