1. 1. Development of rotation electron diffraction as a fully automated and accurate method for structure determination

   Författare :Bin Wang; Xiaodong Zou; Andy Stewart; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; structure determination; structure refinement; metal-organic framework; guest molecules; software development; automation; hierarchical cluster analyses; high-throughput data processing; data merging; frame orientations; least-squares optimization; data processing; TEM goniometer; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Over the past decade, electron diffraction methods have aroused more and more interest for micro-crystal structure determination. Compared to traditional X-ray diffraction, electron diffraction breaks the size limitation of the crystals studied, but at the same time it also suffers from much stronger dynamical effects. LÄS MER

3. 2. Topology optimization of vehicle structures

   Författare :Torbjörn Johansen; Linköpings universitet; []
   Nyckelord :topology optimization; frame structure; vehicle structure; flexible joint; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : This thesis concerns topology optimization of vehicle structures. Vehicle structures are considered to be composed of beams joined together and the work has been focused on a method for beam topology optimization including joints. LÄS MER

4. 3. Design of an Experimental Facility for Investi- gating the Flow in a Low Pressure Turbine Exit Structure

   Författare :Borja Rojo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbine Rear Frame; Turbine Exhaust Case; Experimental; Exit Guide Vane; Engine Exit Structure; Aerodynamics; Outlet Guide Vane; Gas Turbine; Wind Tunnel; Heat transfer.; CFD; Turbine Rear Structure;

   Sammanfattning : This report presents the design of a turbine facility for investigating the flow in the EES located at Chalmers University of Technology. The EES is the structure located downstream of the LPT in a jet engine. In this rig, in order to generate realistic inlet boundary conditions for the EES, an LPT stage is located upstream of the EES.

5. 4. Industrialised timber frame housing : managing customisation, change, and information

   Författare :Max Bergström; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

   Sammanfattning : The overall aim of this thesis is to develop an increased understanding of industrialised timber frame housing (timber frame housing construction fully or partially conducted in a controlled environment utilising industrial processes and machinery). Of specific interest is how industrialised timber frame housing companies manage customisation, change, and information. LÄS MER

7. 5. Micro-Structure Modelling of Acoustics of Open Porous Material

   Författare :Eva Lundberg; Peter Göransson; Per Wennhage; Ulf Orrenius; Camille Perrot; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; porous material; flow resistivity; micro-structure; anisotropic; foam; strut; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : Transportation is a large and growing part of the world’s energy consumption. This drives a need for reduced weight of rail vehicles, just as it does for road vehicles. In spite of weight reductions, the vehicle still has to provide the same level of acoustic comfort for the passengers. LÄS MER
