  2. 21. CFD as a tool for analysis of complex geometry : Perspectives on time efficient simulations of interior household appliance components

    Author : Kamal Rezk; Ola Holby; Lars Davidson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Tumble dryer; Fluid mechanics; Design process; Heat exchanger; Comsol MultiPhysics; Volume averaged method; Fluid mechanics; Strömningsmekanik; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Throughout recent years, computer based programs has been applied to solve and analyze industrial problems. One of these developed programs is the Computational Fluid Dynamics (CFD) program. The purpose of implementing CFD analysis is to solve complex flow behavior which is not possible with ordinary calculus. READ MORE

  4. 22. Mathematical Optimization Models and Methods for Open-Pit Mining

    Author : Henry Amankwah; Torbjörn Larsson; Björn Textorius; Alexandra Newman; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : Open-pit mining is an operation in which blocks from the ground are dug to extract the ore contained in them, and in this process a deeper and deeper pit is formed until the mining operation ends. Mining is often a highly complex industrial operation, with respect to both technological and planning aspects. READ MORE

  5. 23. Large Eddy Simulation of Complex Turbulent Flows

    Author : Magnus Berglund; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gases; fluid dynamics; plasmas; Computational Fluid Dynamics CFD ; Large Eddy Simulation; Complex Turbulent Flows; plasma; Gaser; fluiddynamik;

    Abstract : This thesis concerns the Large Eddy Simulation methodology and its application to predict complex turbulent flows at high Reynolds numbers, and at times also with high Mach numbers. The meaning of the word ?complex? refers both to the presence of complex flow phenomena and the, often, complex geometry of man-made devices restricting the flow. READ MORE

  6. 24. Towards increasing operator wellbeing and performance in complex assembly

    Author : Sandra Mattsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex systems; assembly; operator wellbeing; performance; smart wearables;

    Abstract : This thesis provides insights on complex assembly issues and presents pragmatic models, methods, measurable parameters and prototypes that can be used to support operators in complex assembly. Assembly systems are complex partly because of a high degree of product variety and the strategy of having mass-customised products. READ MORE

  7. 25. Language-Based Techniques and Stochastic Models for Automated Testing

    Author : Claudio Agustin Mista; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automated testing; software testing; stochastic methods; meta-programming; functional programming;

    Abstract : As software systems become bigger and scarier, automating their testing is crucial to ensure that our confidence in them can keep up with their growth. In this setting, Generational Fuzzing and Random Property-Based Testing are two sides of the same testing technique that can help us find bugs effectively without having to spend countless hours writing unit tests by hand.
