1. 11. Pull based production systems : performance, modelling and analysis

   Författare :Jan-Arne Pettersen; Jose M. Framinan; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

   Sammanfattning : This doctoral thesis addresses performances, modelling and analyses of pull based production systems. The thesis consists of four main parts: a literature review, a comparison study of Kanban and CONWIP, an industrial practical case study, and the development of a new tool used for presentation and analysis of simulated performance results.

3. 12. Borehole Thermal Energy Storage Systems for Storage of Industrial Excess Heat : Performance Evaluation and Modelling

   Författare :Emil Nilsson; Patrik Rohdin; Maria Andersson; Mathias Cehlin; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Improving industrial energy efficiency is considered an important factor in reducing carbon dioxide emissions and counteract climate change. For many industrial companies in cold climates, heat generated at the site in summer will not be needed to fulfil the site heat demand during this time, and is thus removed to the outdoor air.

4. 13. Tracking Area Planning in Cellular Networks : Optimization and Performance Evaluation

   Författare :Sara Modarres Razavi; Di Yuan; Calin Curescu; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The enormous competition in the telecommunications market results in the necessity of optimized and cost-efficient networks for the operators and service providers. Tracing users cost-efficiently is one of the major challenges in the study of location management of wireless cellular  networks. LÄS MER

5. 14. Performance of MCrAlX coatings : Oxidation, Hot corrosion and Interdiffusion

   Författare :Pimin Zhang; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Ping Xiao; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : MCrAlY coatings (M=Ni and/or Co) are widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive for coating systems to bestow adequate oxidation and corrosion resistance upon the components becomes urgent as an inevitable result of the necessary improvement in engine combustion efficiency and service lifetime.

7. 15. Small-Scale Decentralized Energy Systems : optimization and performance analysis

   Författare :Sara Ghaem Sigarchian; Viktoria Martin; Anders Malmquist; Erik Dahlquist; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Small-scale polygeneration energy systems; techno-economic optimization; renewable energy; operating strategy; particle swarm optimization; optimization algorithm; decentralized energy system;

   Sammanfattning : Small-scale polygeneration energy systems, providing multiple energy services, such as heating, electricity, cooling, and clean water, using multiple energy sources (renewable and non-renewable) are considered an important component in the energy transition movement. Exploiting locally available energy sources and providing energy services close to the end users have potential environmental, economic, and societal benefits. LÄS MER
