1. 1. Theoretical Investigation into Longitudinal Dispersion in Natural Rivers — A Scaling Dispersion Model

   Författare :Zhi-Qiang Deng; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil mechanics; Väg- och vattenbyggnadsteknik; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; offshore technology; hydraulic engineering; Civil engineering; Scaling dispersion.; Parameter estimation; Numerical scheme; Dispersion coefficient; Natural river;

   Sammanfattning : Using a broad variety of scientific methods this dissertation systematically investigates the fundamental mechanisms underlying the dispersion processes in natural rivers and their mathematical descriptions in a geometrical framework. Emphasis is on the geometrical variations and irregularities of a natural river and their scales. LÄS MER

3. 2. In the Pipe or End of Pipe? : Transport and Dispersion of Water-borne Pollutants and Feasibility of Abatement Measures

   Författare :Christoffer Carstens; Vladimir Cvetkovic; Auli Niemi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Contaminant transport modelling; Groundwater; Dispersion; Wave power; Eutrophication;

   Sammanfattning : Eutrophication is one of the key environmental problems of today, both in terms of complexity and magnitude. For the Baltic Sea (BS), eutrophication is an acute problem, leading to hypoxic conditions at the bottom; a situation that is sustained and amplified, when phosphorus is released from hypoxic sediments.

4. 3. Robust Design Experimentation and Dispersion Effects

   Författare :Martin Arvidsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; estimation procedure; design of experiments; generalized linear models; event matrices; variance component; location effects; split-plot experiments; robust design; identification procedure; dispersion effects;

   Sammanfattning : One of the most common methods in robust design methodology is design of experiments. This method makes it possible to identify settings of design factors that make products and production processes robust with respect to noise factors. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

7. 5. Computational modeling of biological barriers

   Författare :Christian Wennberg; Erik Lindahl; Thomas Cheatham; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; cholesterol; lipid bilayer; permeability; long-range interactions; Lennard-Jones; dispersion; particle-mesh Ewald; stratum corneum; skin formation; Biological Physics; Biologisk fysik;

   Sammanfattning : One of the most important aspects for all life on this planet is the act to keep their biological processes in a state where they do not reach equilibrium. One part in the upholding of this imbalanced state is the barrier between the cells and their surroundings, created by the cell membrane. LÄS MER
