  1. 26. Land Mine Detection using Dual-Band Electro-Optical Sensing

    Författare :Magnus Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; land mines; regularization; nuisance parameters; detection; infrared imaging; occlusion modeling; multi-spectral imaging; prior knowledge; Signalbehandling;

    Sammanfattning : This thesis addresses the detection of buried and partially occluded land mines using electro-optical sensing. According to the Red Cross approximately 10000 people are killed and another 30000 are injured each year in mine related accidents. LÄS MER

  3. 27. Highly Concentrated Electrolytes for Lithium Batteries : From fundamentals to cell tests

    Författare :Viktor Nilsson; Kristina Edström; Patrik Johansson; Erik Berg; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; SEI; Highly concentrated electrolyte; Al corrosion; Li metal battery;

    Sammanfattning : The electrolyte is a crucial part of any lithium battery, strongly affecting longevity and safety. It has to survive rather severe conditions, not the least at the electrode/electrolyte interfaces. LÄS MER

  4. 28. Reactive Objects and Functional Programming

    Författare :Johan Nordlander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The construction of robust distributed and interactive software is still a challenging task, despite the recent popularity-increase for languages that take advanced programming concepts into the mainstream. Several problematic areas can be identified: most languages require the reactivity of a system to be manually upheld by careful avoidance of blocking operations; mathematical values often need to be encoded in terms of stateful objects or vice versa; concurrency is particularly tricky in conjunction with encapsulated software components; and static type safety is often compromised because of the lack of simultaneous support for both subtyping and polymorphism.

  5. 29. Adaptive Finite Element Methods for Optimal Control Problems

    Författare :Karin Kraft; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dual weighted residual; adaptive; Newton method; variational inequality; vehicle dynamics.; multilevel algorithm; discontinuous Galerkin method; a posteriori error estimate; finite element method; optimal control; control constraint;

    Sammanfattning : In this thesis we study the numerical solution of optimal control problems. The problems considered consist of a systemof differential equations, the state equations, which are governed bya control variable. The goal is to determine the states and controls which minimize a given cost functional. LÄS MER

  7. 30. Quality-Driven Production of Aggregates in Crushing Plants

    Författare :Magnus Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; breakage; crushing; simulation; modelling; Keywords: aggregate quality; particle shape;

    Sammanfattning : Aggregate quality is of great importance, and in this context it is essential to understand how various process parameters influence the product quality characteristics. Thus, there is a need for aggregate producers to improve their process knowledge. LÄS MER
