En viktig uppgift för alla företag är att sälja sin kompetens. För många företag innebär det bland annat att locka in besökare i ett utställningsbås på de många yrkesmässorna runt om i världen. Med detta som avsikt beslutade sig Motion Contol i Västerås AB att annonsera ut ett examensarbete med inriktningen att utveckla ett ?publikfång? i form av ett stort visionbaserat x/y-system. Besökaren kastar en boll mot x/y-systemet var på den fångar in bollen med Visionsystemet till hjälp.För att lösa uppgiften krävs att de rörliga delarna i det mekaniska systemet hålls så lätta som möjligt.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

The report describes the process of identifying the interference that exists in a newly installed automated robotic cell and suggest improvements to increase productivity. The cell is used for lifting up extruded aluminum sections onto a conveyor which deliver the material to a anodising line at a company that manufactures aluminum extrusions.To find the areas with the best possibility for improvements in the cell we used a variety of job measurements e.g. measure of standard times for each operation in the cell. The core of the report is a study of the robots.One reason for this study is that the robots do not reach the productivity they were purchased to. The main cause not reaching the productivity is the Visionsystem.

To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
