  2. 26. Random Geometry and Reinforced Jump Processes

    Author : Tuan-Minh Nguyen; Probability and Inference Theory Group; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; random polygons; products of random matrices; vertex-reinforced jump processes; pseudotrajectories; random walks in simplexes; Markov chains in a general state space;

    Abstract : This thesis comprises three papers studying several mathematical models related to geometric Markov processes and random processes with reinforcements. The main goal of these works is to investigate the dynamics as well as the limiting behaviour of the models as time goes to infinity, the existence of invariant measures and limiting distributions, the speed of convergence and other interesting relevant properties.

  4. 27. A Microwave Tomography Framework for Monitoring of Pharmaceutical Processes

    Author : Livia Cerullo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensitivity Analysis; Microwave Tomography; Reconstruction Algorithm; Parameterization; Pharmaceutical Processes;

    Abstract : Industrial pharmaceutical processes may be very difficult to monitor and control. Today, an important research fields is non-invasive measurement techniques that provide information about thematerial distribution inside the process. In this thesis, a microwave tomography (MWT) framework for monitoring of pharmaceutical processes is presented. READ MORE

  5. 28. Local environmental governance: Assessing proactive initiatives in building energy efficiency

    Author : Nora Smedby; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local governance; policy evaluation; building energy efficiency; sustainability transitions; polycentric governance;

    Abstract : Local governments are increasingly taking the initiative in environmental governance. But can they make any difference in addressing current environmental challenges, which are becoming more and more global in scope? This PhD thesis explores and analyses the outcomes of proactive initiatives in the field of building energy efficiency, and the governance approaches taken. READ MORE

  6. 29. A Non-Gaussian Limit Process with Long-Range Dependence

    Author : Raimundas Gaigalas; Ingemar Kaj; Esko Valkeila; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; long-range dependence; traffic modelling; arrival process; self-similarity; heavy tails; fractional Brownian motion; stable processes; renewal processes; independently scattered random measure; weak convergence; 60F17; 60G18; 90B18; 60K05 ; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Abstract : This thesis, consisting of three papers and a summary, studies topics in the theory of stochastic processes related to long-range dependence. Much recent interest in such probabilistic models has its origin in measurements of Internet traffic data, where typical characteristics of long memory have been observed. READ MORE

  7. 30. Global Spaces for Local Entrepreneurship : Stretching clusters through networks and international trade fairs

    Author : Marcela Ramírez-Pasillas; Bengt Johannisson; Sven-Åke Hörte; Poul Rind Christensen; Växjö universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; clusters; international trade fairs; proximity; networks; organising contexts; Business studies; Företagsekonomi;

    Abstract : Many of the insightful writings on clusters identify the role of entrepreneurs as key agents in the formation of firms and clusters. This thesis argues instead that local entrepreneurship is not ceased once firms and clusters are established; local entrepreneurship is about the continuous (re)creation of both businesses and clusters in global spaces.
