1. 21. Continuum models and numerical methods for tribological systems

   Författare :Peter Jarl Ireman; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : This thesis concerns the formulation of continuum mechanical models and the development of numerical methods for frictional heating, wear and damage in tribological systems.The models are formulated in the spirit of generalized standard materials, i.e. LÄS MER

3. 22. High performance hybrid mixed elements using orthogonal stress interpolants and scaling of the higher order stiffness

   Författare :Anders Sundin; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : During the evolution of the finite element method, formulations based on the principle of minimum potential energy have dominated the scene. These formulations employ an assumed displacement field within each element which must preserve continuity of displacements between adjacent elements. LÄS MER

4. 23. Novel methods and software for disease module inference

   Författare :Hendrik Arnold de Weerd; Mika Gustafsson; Zelmina Lubovac; Natasa Przulj; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Cellular organization is believed to be modular, meaning cellular functions are carried out by modules composed of clusters of genes, proteins and metabolites that are interconnected, co-regulated or physically interacting. In turn, these modules interact together and thereby form complex networks that taken together is considered to be the interactome. LÄS MER
