  2. 2. Impact of moisture on long term performance of insulating products based on stone wool

    Författare :Tomás Vrána; Folke Björk; Per Ingvar Sandberg; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral insulation; Stone wool; Material properties; Moisture transport; Heat transport; Test equipment; Moisture properties; Frost formation; Building engineering; Byggnadsteknik;

    Sammanfattning : Demands for energy have been increasing in the whole world. According to higher consumption, the price of energy rises yearly too. This evokes usage of insulating products in a wider range. LÄS MER

  3. 3. Condensation and frost formation in fibrous thermal-insulation materials

    Författare :Tomáš Vrána; Folke Björk; Ove Söderström; Kjartan Gudmundsson; Carsten Rode; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibrous thermal insulation; Stone wool; Cellulose; MAterial properties; Moisture transport; Condensation; Frost formation; Exterior conditions; Interior conditions; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Construction materials; Konstruktionsmaterial;

    Sammanfattning : Heavily insulated constructions are at present being used to strike at the vast energy consumption in residential buildings and commercial alike. They introduce a high-thickness layer of thermal insulation in the building envelopes. LÄS MER

  4. 4. Necessary Optimality Conditions for Two Stochastic Control Problems

    Författare :Daniel Andersson; Boualem Djehiche; Tomas Björk; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik;

    Sammanfattning : This thesis consists of two papers concerning necessary conditions in stochastic control problems. In the first paper, we study the problem of controlling a linear stochastic differential equation (SDE) where the coefficients are random and not necessarily bounded. We consider relaxed control processes, i.e. LÄS MER

  5. 5. Cooperation in local electricity markets : modelling of technical measures

    Författare :Maria Andersson; Björn Karlsson; Curt Björk; Tomas Larsson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system; System cost; Electricity market; Co-operation; Demand-side management; Energy efficiency; Shadow prices;

    Sammanfattning : This thesis presents a system analysis for co-operation in local electricity markets including distributors and customers. The purpose of co-operation is to minimise the system cost of local markets by introducing system measures, such as end-use measures and municipal co-generation plants. LÄS MER
