  2. 21. Scaling effects and homogenization of reaction-diffusion problems with nonlinear drift

    Author : Vishnu Raveendran; Adrian Muntean; Irina Pettersson; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; homogenization; asymptotic expansion with drift; two-scale convergence with drift; effective transmission condition; dimension reduction; two-scale system; nonlinear dispersion; Matematik; Mathematics;

    Abstract : We study the periodic homogenization of reaction-diffusion problems with nonlinear drift describing the transport of interacting particles in composite materials. The microscopic model is derived as the hydrodynamic limit of a totally asymmetric simple exclusion process for a population of interacting particles crossing a domain with obstacles.

  4. 22. Deciding on Sourcing Option for Hosting of Software Applications in Organisations

    Author : Björn Johansson; Sven Carlsson; Göran Goldkuhl; Ulf Melin; Anders G. Nilsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; resource-based view; sourcing decision; hosting of software applications; decision-making processes; beslutsfattande; beslutsprocesser; drift av mjukvaruapplikationer; lokaliseringsbeslut; resursbaserad teori; Informatics; Informatik;

    Abstract : Software applications are of great importance in organisations, and performance of an organisation depends on how hosting of software applications are organised. This thesis deals with the question: Why and how organisations decide on specific sourcing options for software applications hosting. READ MORE

  5. 23. Maintenance strategy for a railway infrastructure in a regulated environment

    Author : Ulla Espling; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : The operation and maintenance of railway infrastructure is complex, strictly regulated by government legislation, and must be working in close cooperation with all the stakeholders including customers involved, in order to avoid sub optimization. The business configuration of the Swedish Railway system makes it very difficult to optimize the entire railway operation, as many times its stakeholders have conflicting demands. READ MORE

  6. 24. Bush Encroachment and the Role of Browse in Cattle Production : An ecological perspective from a bush encroached grazing system, Olifants Drift, Kgatleng District, Southeast Botswana

    Author : Nkobi Moleele; Norman Owen-Smith; Stockholms universitet; []
    Keywords : savannas; bush encroachment; carrying capacity; browse; biomass; range degradation; colour infrared photographs; Landsat Thematic Mapper; mid infrared bands; tannins; toxins; aromatic substances; Dicrostachys cinerea; Grewia flava; NDVI; Olifants Drift; Botswana; naturgeografi; Physical Geography;

    Abstract : The increase in density and cover of woody plant species is coincident with the introduction of cattle in southern Africa, and it is a wide spread phenomenon in the savannas of the world. The causes are little understood, but can only be speculated to be either anthropogenic or natural or a combination of both. READ MORE

  7. 25. Methods for availability improvements of a scaling machine system

    Author : Andi Rahadiyan Wijaya; Jan-Gunnar Persson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Scaling is the process of cleaning loose material from the roof, face and wall of the mine room in underground mining. The purpose of scaling is to make the mine room safe for the next operation. Due to the nature of the task, scaling has been identified as an operation with a high number of accident occurrences.
