  3. 22. Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

    Författare :Jonathan Karlsson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; aggregates; heat capacity; thermal properties; thermal conductivity; thermal inertia; thermal mass; time constant; Energy storage;

    Sammanfattning : The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good thermal comfort also in case of higher outdoor temperatures resulting from global warming.

  4. 23. Recursive Methods in Urn Models and First-Passage Percolation

    Författare :Henrik Renlund; Sven Erick Alm; Svante Janson; John Wierman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stochastic approximation algorithm; generalized Polya urn; limit theorem; first-passage percolation; rate of percolation; time constant; Mathematical statistics; Matematisk statistik; Mathematical Statistics; Matematisk statistik;

    Sammanfattning : This PhD thesis consists of a summary and four papers which deal with stochastic approximation algorithms and first-passage percolation. Paper I deals with the a.s. limiting properties of bounded stochastic approximation algorithms in relation to the equilibrium points of the drift function. LÄS MER

  5. 24. Risk, Time and Land Management under Market Imperfections: Applications to Ethiopia

    Författare :Mahmud Yesuf; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; land degradation; market imperfections; transaction costs; soil conservation; fertilizer adoption; risk preference; time preference; experimental studies; Ethiopia;

    Sammanfattning : This Ph.D. thesis addresses both theoretical and empirical issues pertaining to land management decisions of farm households in developing countries working under an imperfect market and institutional setting (with case studies from Ethiopia). LÄS MER

  7. 25. On the thermal inertia and time constant of single-family houses

    Författare :Johan Hedbrant; Björn Karlsson; Mats Söderström; Stig-Inge Gustafsson; Karin Adalberth; Linköpings universitet; []
    Nyckelord :Electric heating;

    Sammanfattning : Since the nineteen-seventies, electricity has become a common heating source in Swedish single-family houses. About one million smallhouses can use electricity for heating, about 600.000 have electricity as the only heating source. LÄS MER
