2. 16. Capacity Management Approaches for Compute Clouds

   Author : Mina Sedaghat; Erik Elmroth; Sarunas Girdzijauskas; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cloud computing; Capacity Management; business data processing; administrativ databehandling;

   Abstract : Cloud computing provides the illusion of a seamless, infinite resource pool with flexibleon-demand accessibility. However, behind this illusion there are thousands ofservers and peta-bytes of storage, running tens of thousands of applications accessedby millions of users. READ MORE

4. 17. Categorical Unification

   Author : María Ángeles Galán García; Patrik Eklund; José Meseguer; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Monad compositions; generalised terms; many-valued logic; Datalogi; Computer science; Datalogi; business data processing; administrativ databehandling;

   Abstract : This thesis deals with different aspects towards many-valued unification which have been studied in the scope of category theory. The main motivation of this investigation comes from the fact that in logic programming, classical unification has been identified as the provision of coequalizers in Kleisli categories of term monads.

5. 18. Representing and Reasoning about Complex Human Activities - an Activity-Centric Argumentation-Based Approach

   Author : Esteban Guerrero Rosero; Helena Lindgren; Juan Carlos Nieves; Chris Reed; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex activity; Argumentation Theory; Activity Theory; Logic programming; Knowledge representation; Common-sense reasoning; Artificial Intelligence; business data processing; administrativ databehandling;

   Abstract : The aim of this thesis is to develop theories and formal methods to endow a computing machinery with capabilities to identify, represent, reason and evaluate complex activities that are directed by an individual’s needs, goals, motives, preferences and environment, information which can be inconsistent and incomplete.Current methods for formalising and reasoning about human activity are typically limited to basic actions, e.

6. 19. Topology optimization of antennas and waveguide transitions

   Author : Emadeldeen Hassan; Martin Berggren; Daniel Noreland; Eddie Wadbro; Mats Gustafsson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Maxwell s equations; topology optimization; antennas; waveguide transition; finite-difference time-domain; gradient-based optimization; adjoint-field problem; microwave devices.; business data processing; administrativ databehandling;

   Abstract : This thesis introduces a topology optimization approach to design, from scratch, efficient microwave devices, such as antennas and waveguide transitions. The design of these devices is formulated as a general optimization problem that aims to build the whole layout of the device in order to extremize a chosen objective function. READ MORE

7. 20. Analysis, Control, and Design Optimization of Engineering Mechanics Systems

   Author : Esubalewe Lakie Yedeg; Martin Berggren; Eddie Wadbro; Anton Evgrafov; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Topology optimization; Helmholtz equation; acoustic impedance; anisotropic filter; thin structures; finite element method; Nitsche-type method; interface problem; Optimal control; adjoint method; business data processing; administrativ databehandling;

   Abstract : 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.
