2. 1. Control Aspects of Complex Hydromechanical Transmissions : with a Focus on Displacement Control

   Author : L. Viktor Larsson; Petter Krus; Björn Eriksson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis deals with control aspects of complex hydromechanical transmissions. The overall purpose is to increase the knowledge of important aspects to consider during the development of hydromechanical transmissions to ensure transmission functionality. READ MORE

4. 2. Fine particle emissions and slag formation in fixed-bed biomass combustion : aspects of fuel engineering

   Author : Jonathan Fagerström; Christoffer Boman; Dan Boström; Marcus Öhman; Bengt-Johan Skrifvars; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy; biomass; thermochemical fuel conversion; combustion; fine particle emissions; slag formation; fixed-bed; ash chemistry; fuel engineering; release;

   Abstract : There is a consensus worldwide that the share of renewable energy sources should be increased to mitigate climate change. The strive to increase the renewable energy fraction can partly be met by an increased utilization of different biomass feedstocks. READ MORE

5. 3. In conversation with simulation: The application of numerical simulation to the design of structural nodal connections

   Author : Jens Olsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; 3D Printing; Design theory; Structural design; Structural efficiency; Simulation; Peridynamics; Force flux density; Nodal connections; Conceptual design; Steel structures; Design process; Digital design;

   Abstract : The thesis explores methods for integration of structural analysis, design and production in a digital design environment. The somewhat ambiguous title implies the ambition to make such integration in relation to the explorative phase of the design process which is described by Donald Schön as having a conversational character.

6. 4. Particulate Formation in GDI Engines

   Author : Sreelekha Etikyala; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PM; Alternate fuels; Gasoline Direct Injection; internal combustion engines; Particulate Number; Load transients;

   Abstract : The need to comply with stringent emission regulations while improving fuel economy and reducing criteria pollutant emissions from transportation presents a major challenge in the design of gasoline Direct Injection (DI) engines because of the adverse effects of ultrafine Particulate Number (PN) emissions on human health and other environmental concerns. With upcoming advances in vehicle electrification, it may be the case that electric vehicles completely replace all current vehicles powered by internal combustion engines ensuring zero emissions.

7. 5. Knitted architecture and wind: Designing loosely fitted architectural textiles for interaction with wind

   Author : Erica Hörteborn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Textile architecture; Knitted textiles; Wind performance; Wind; Research by design; Kinetic architecture; Geometric expression; Wind simulation; Architectural design;

   Abstract : Utilising the textile’s ability to adapt to external forces such as the wind could lead to the creation of new design expressions and functional features within architecture. Prompted by architectural potentials of textiles deliberately designed to move and flex, this thesis aims to explore and demonstrate how such knitted textiles could contribute to enriched aesthetic expression and improved performance of architectural elements placed in windy environments.
