1. 21. Stability analysis of channel flow laden with small particles

   Författare :Joy Klinkenberg; Luca Brandt; Cristian Marchioli; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; Direct Numerical Simulations; multi-phase flow; heavy particles; light particles; particle-laden;

   Sammanfattning : This thesis deals with the stability of particle laden flows. Both modal and non-modal linear analyses have been performed on two-way coupled particleladen flows, where particles are considered spherical, solid and either heavy or light. When heavy particles are considered, only Stokes drag is used as interaction term. LÄS MER

   Sammanfattning : Antibiotic resistance is an emerging and serious threat to public health. Immediate actions are required to preserve current antibiotics while intensifying research efforts towards the development of new effective therapeutics. LÄS MER

4. 23. Assembling and Unraveling Carbohydrates Structures : Conformational analysis of synthesized branched oligosaccharides

   Författare :Thibault Angles d'Ortoli; Göran Widmalm; Christian Marcus Pedersen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Convergent carbohydrate synthesis; Super-armed donors; Glycosylation; Conformational analysis; NMR; Chemical shift prediction; organisk kemi; Organic Chemistry;

   Sammanfattning : Advances in the elaboration of vaccines and enzyme inhibitors rely on acquiring more knowledge about protein-carbohydrate binding events. Furthermore, the relationships between biological function and the three-dimensional properties of large glycans can be studied by focusing on the structural components they contained, namely, by scaling down the system under analysis.

5. 24. Hybrid and Dynamic Substructuring Methods for Energy Flow Analysis

   Författare :Anders Wilson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fractional derivatives; structural modeling; mid-frequency; finite element method FEM; vibro-acoustics; statistical energy analysis SEA; dynamic substructuring; hybrid analysis; viscoelasticity;

   Sammanfattning : Modeling techniques and solution tools to analyze the dynamic and vibro-acoustic behavior of complex built-up structures are matters of increasing interest, especially for thin walled structures as in transportation vehicles, such as automobiles, trucks, trains and aircraft. In structures like these, the reduction of cost, weight, sound and vibration levels are primary issues for research and development. LÄS MER

7. 25. Analysis of the Fatigue Characteristics of Mooring Lines and Power Cables for Floating Wave Energy Converters

   Författare :Shun-Han Yang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mooring line; power cable; fatigue; coupled analysis; power absorption; experiment; wave energy converter; heaving point absorber; computational modelling; marine biofouling effect on fatigue;

   Sammanfattning : To reduce greenhouse gas emissions and expand the energy mix, there is a pressing need for the exploitation of renewable sources of energy, such as biomass, hydropower, solar power, waves, and wind. This thesis focuses on ocean wave energy and its applications. LÄS MER
