16. Analysis, Control, and Design Optimization of Engineering Mechanics Systems
Sammanfattning : This thesis considers applications of gradient-based optimization algorithms to the design and control of some mechanics systems. The material distribution approach to topology optimization is applied to design two different acoustic devices, a reactive muffler and an acoustic horn, and optimization is used to control a ball pitching robot.

17. Dimensioning Tools of MEA Actuator Systems, Including Modeling, Analysis and Technology Comparison
Sammanfattning : Aircraft design is an example of complex engineering where dimensioning tools can be valuable for the designers and decision makers in the early stage of the development process. These tools can be in form of a database over key numbers for different components or technologies. One of the critical parts of an aircraft is the actuator system. LÄS MER
18. Oligomerization of human and bacterial frataxin : Structural and functional studies
Sammanfattning : Friedreich’s ataxia (FRDA) is an autosomal recessive neurodegenerative disease caused by defeciency in frataxin, a highly conserved protein central to iron homeostasis in mirochondria. The function of frataxin is related to its capability to bind, store and deliver iron to different biochemical process such as iron-sulfur cluster assembly and heme biosynthesis. LÄS MER
19. Identification and functional characterization of novel thioredoxin systems
Sammanfattning : Thioredoxins (Trx) are a class of small multifunctional 12-kDa proteins that are characterized by the redox active site Trp-Cys-Gly-Pro-Cys (WCGPC). In the oxidized (inactive) form of Trx (Trx-S2), the two cysteines at the active site form a disulfide bond. LÄS MER
20. Magnetic Fields and Induced Power in the Induction Heating of Aluminium Billets
Sammanfattning : Induction heating is a common industrial process used for the reheating of billets before extrusion or forging. In this work the influence of the coil and work piece geometry, the effect of the electrical properties of the work piece, and the coil current and frequency, on the magnetic flux density and resulting work piece heating rates were studied.
