  2. 1. Property Maintenance : Concepts and determinants

    Author : Henry Muyingo; Hans Lind; Göran Lindahl; KTH; []
    Keywords : Housing maintenance; property management; real estate; housing companies;

    Abstract : Introduction Strategic property management aims at balancing the question of how the needed space is to be secured, maintained, increased or disposed of in a cost effective manner under a mixture of decisions and actions. In recent years, the interest in building maintenance has increased as more and more of the housing stock built after the Second World War is in need of major renovation. READ MORE

  4. 2. On maintenance management of wind and nuclear power plants

    Author : Julia Nilsson; Lina Bertling; Ulf Sandberg; KTH; []
    Keywords : electrical poduction systems; windpower; nuclear power; maintenance management; RCM; RCAM; LCC; mathematical optimization; opportunistic maintenance;

    Abstract : Electrical production in Sweden today is mainly from nuclear and hydro power. However, there is large increase in renewable energy like wind power and the installed new capacity goals are large. Several electrical production sources are important for the sustainability of the energy system. READ MORE

  5. 3. On the optimization of opportunistic maintenance activities

    Author : Adam Wojciechowski; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mixed integer linear programming; stochastic programming; complexity theory; mixed integer linear programming; complexity theory; stochastic programming;

    Abstract : Maintenance is a source of large costs; in the EU the maintenance costs amountto between 4% and 8% of the total sales turnover. Opportunistic maintenance is anattempt to lower the maintenance cost by considering the failure of onecomponent as an opportunity to replace yet non-failed components in order toprevent future failures.

  6. 4. Polyhedral and complexity studies in integer optimization, with applications to maintenance planning and location–routing problems

    Author : Adam Wojciechowski; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; integer linear programming; complexity theory; polyhedral analysis; stochastic programming; maintenance optimization; Hamiltonian p-median problem; maintenance optimization;

    Abstract : This thesis develops integer linear programming models for and studies the complexity of problems in the areas of maintenance optimization and location–routing. We study how well the polyhedra defined by the linear programming relaxation of themodels approximate the convex hull of the integer feasible solutions. READ MORE

  7. 5. Nutri-medicinal plants used in the management of HIV/AIDS opportunistic infections in western Uganda : documentation, phytochemistry and bioactivity evaluation

    Author : Savina Asiimwe; Anna Karin Borg Karlsson; Jasper Ogwal-Okeng; KTH; []
    Keywords : Ethnobotanical study; Medicinal plants; HIV; AIDS; opportunistic infections; bacteria; fungi; GC-MS; phytochemistry; SPME; antioxidant; histopathology; biochemistry; hematology; western Uganda.; Kemi; Chemistry;

    Abstract : As a result of the AIDS epidemic, many people are immunocompromised and opportunistic infections are common. Medicinal plants constitute one of the fundaments of HIV treatment and are commonly used in management of HIV–related ailments, and also to counteract the side effects of antiretroviral therapy.
