1. 21. Active Junction Control and Piezoelectric Hybrid Damping for Improving the Acoustic Performance of Lightweight Structures

   Författare :Jonas Svensson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid passive-active control; Piezoelectric shunt damping; Sound radiation; Active junction control;

   Sammanfattning : Weight reduction is a key factor in lowering the fuel consumption and thereby the greenhouse emissions from vehicles. However, reducing the weight normally results in a deterioration of the acoustic performance. Thus, the purpose of this thesis is to investigate damping treatments for lightweight vehicle panels.

3. 22. Design of Reconfigurable Hardware Architectures for Real-time Applications

   Författare :Thomas Lenart; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stream Processing; Digital Holography; Reconfigurable Computing; Reconfigurable Architectures; Run-time Reconfiguration; Design Exploration; Hybrid floating-point; Data Scaling; FFT; ASIC;

   Sammanfattning : This thesis discusses modeling and implementation of reconfigurable hardware architectures for real-time applications. The target application in this work is digital holographic imaging, where visible images are to be reconstructed based on holographic recordings. LÄS MER

4. 23. Recombinant CXCR4/CCR5 hybrid receptors as tools for studies of HIV-1 receptor usage

   Författare :Liselotte Antonsson; Drug Target Discovery; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; evolution; pathogenesis; cerebrospinal fluid; Medicine human and vertebrates ; TAK-779; RANTES; CXCR4; CCR5; coreceptor; GPCR; HIV-1;

   Sammanfattning : The chemokine receptors CCR5 and CXCR4 are required, together with CD4, for the entry of HIV-1 into target cells. CCR5 using HIV-1 dominates during transmission and the asymptomatic phase of infection. During progression, virus phenotypes with the ability to use CXCR4 emerge in about 50% of infected individuals.

5. 24. Comparison of Different Electrical Machines for Belt-driven Alternator and Starter

   Författare :Dan Hagstedt; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Belt-driven Alternator and Starter; Permanently Magnetised Synchronous Machine; Electrically Magnetised Synchronous Machine; Series Magnetisation Synchronous Machine; Hybrid Magnetised Synchronous Machine;

   Sammanfattning : This thesis focuses on the electromagnetic design of a synchronous machine suited for a belt-driven alternator and starter (BAS) in a micro hybridisation of a mid-size passenger car. The BAS needs to provide a high cranking torque to start the combustion engine, especially in a cool condition where the requirements are highest. LÄS MER

7. 25. Towards Optimal Real-Time Automotive Emission Control

   Författare :Jonathan Lock; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic programming; optimal control methods; hybrid vehicles; three way catalyst modelling; Automotive emissions control;

   Sammanfattning : The legal bounds on both toxic and carbon dioxide emissions from automotive vehicles are continuously being lowered, forcing manufacturers to rely on increasingly advanced methods to reduce emissions and improve fuel efficiency. Though great strides have been made to date, there is still a large potential for continued improvement. LÄS MER
