2. 1. Well Testing, Methods and Applicability

   Author : Jan-Erik Rosberg; Teknisk geologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slug tests; well completion; re-injection; Well testing; pumping tests; injection tests; well development; pneumatic initiation; hydro-jetting; coiled tubing; tunnel lining; deep wells;

   Abstract : Well testing is widely used today in water wells, oil and gas wells, for geothermal applications, within civil engineering projects, thermal storage and CO2 storage. The overall testing goal is to verify the productivity from a well and/or for characterization of hydraulic and thermal properties, as well as the spatial limitations of an aquifer. READ MORE

4. 2. Completion of Ontologies and Ontology Networks

   Author : Zlatan Dragisic; Patrick Lambrix; Nahid Shahmehri; Marco Kuhlmann; Fang Wei-Kleiner; Erhard Rahm; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; knowledge representation; ontology; ontology engineering; ontology debugging; ontology completion; ontology matching; description logics;

   Abstract : The World Wide Web contains large amounts of data, and in most cases this data has no explicit structure. The lack of structure makes it difficult for automated agents to understand and use such data. A step towards a more structured World Wide Web is the Semantic Web, which aims at introducing semantics to data on the World Wide Web. READ MORE

5. 3. Exact completion and type-theoretic structures

   Author : Jacopo Emmenegger; Erik Palmgren; Alexander Berglund; Maria Emilia Maietti; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; exact completion; type theory; setoid; weak limits; cartesian closure; inductive types; Mathematics; matematik;

   Abstract : This thesis consists of four papers and is a contribution to the study of representations of extensional properties in intensional type theories using, mainly, the language and tools from category theory. Our main focus is on exact completions of categories with weak finite limits as a category-theoretic description of the setoid construction in Martin-Löf's intensional type theory. READ MORE

6. 4. Perspectives on living with coeliac disease in remission : Daily life experiences, symptoms and well-being

   Author : Lisa Ring Jacobsson; Maria Friedrichsen; Claes Hallert; Anna Milberg; Katarina Hjelm; Ella Danielsson; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chronic disease; illness experience; patient education; PBL; phenomenology; residual discomfort; well-being.;

   Abstract : Background and aims: Despite living with a gluten-free diet (GFD) Swedish women with coeliac disease (CD) report a lower level of well-being than women without the disease and men with the disease. The all-embracing aim of the thesis was to study experiences of living with coeliac disease in remission and to discover whether a patient education intervention can influence the perceived health and daily life of women with coeliac disease.

7. 5. Rank Reduction with Convex Constraints

   Author : Christian Grussler; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-rank approximation; model reduction; non-convex optimization; Douglas-Rachford; matrix completion; overlapping norm; k-support norm; atomic norm;

   Abstract : This thesis addresses problems which require low-rank solutions under convex constraints. In particular, the focus lies on model reduction of positive systems, as well as finite dimensional optimization problems that are convex, apart from a low-rank constraint. READ MORE
