  2. 1. Studies of water vapor transport and sorption in wood

    Author : Lars Wadsö; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evaluation; measurements; non-Fickian behavior; absorption; sorption method; transient; unsteady-state; wood; sorption; surface mass transfer coefficient; water vapor; error analysis;

    Abstract : This thesis deals with the evaluation of measurements of water vapor transport and sorption in wood. It mainly concerns measurements of the weight response of a sample after a step change in relative humidity. The thesis consists of an introduction and eight papers. The eight papers have the following contents: 1. READ MORE

  4. 2. Failure Monitoring and Asset Condition Assessment in Water Supply Systems

    Abstract : In this thesis, different aspects of failure management in urban water supply systems are discussed. As assets are getting older, the number of pipe failures is increasing and an efficient failure management strategy becomes important. READ MORE

  5. 3. Theoretical Modeling and Near-Infrared Spectroscopy Monitoring of Vial Lyophilization

    Author : Mikael Brülls; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-situ; simulation; monitoring; spectral peak area analysis; near-infrared spectroscopy; lyophilization; moisture; sublimation; vial; mathematical model;

    Abstract : The research documented in this thesis was directed towards lyophilization of pharmaceuticals in vials (vial lyophilization) and it was focused on the design and control of this process. Theoretical modeling has considerable potential to guide experimental studies, thereby decreasing development time and improving the possibilities to achieve an optimal and robust process design.
