1. 1. Graphic Representation and Visualisation as Modelling Support for the Knowledge Acquisition Process

   Författare :Anne Håkansson; Andreas Hamfelt; Harald Kjellin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Artficial Intelligence; Knowledge-Based Systems; Knowledge Acquisition; Graphic Representation; Visualisation; Unified Modelling Language; Modelling Rule-based Systems; Visual programming; Declarative Programming; Information Networks; User-Centered Design; Knowledge Interface; Datavetenskap; Computer science; Datavetenskap; datalogi; Computer Science;

   Sammanfattning : The thesis describes steps taken towards using graphic representation and visual modelling support for the knowledge acquisition process in knowledge-based systems – a process commonly regarded as difficult. The performance of the systems depends on the quality of the embedded knowledge, which makes the knowledge acquisition phase particularly significant. LÄS MER

   Sammanfattning : This thesis deals with various aspects of coordinated voltage control in electric power systems. It consists of an introduction and six papers. The introduction contains a summary of the thesis and tutorials on voltage control and the search methods that have been applied. LÄS MER

4. 3. Methods and tools for object-oriented modelling and knowledge-based simulation of complex biomedical systems

   Författare :Mikael Hakman; Uppsala universitet; []
   Nyckelord :Medical sciences; Object-oriented modelling; knowledge-based simulation; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; medicinsk informatik; medicinsk informatik;

   Sammanfattning : An environment for interactive knowledge-based simulation was developed. Theenvironment known as KBSIM integrates quantitative continuous model simulationwith rule-based expert system reasoning techniques with relational databasemanagement technology under the control of a user interface management system.

5. 4. Optimal Control of Electric Bus Lines

   Författare :Rémi Lacombe; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eco-driving; Electric buses; Bus bunching; Nonlinear programming; Optimal control; Model predictive control;

   Sammanfattning : Bus lines are inherently unstable systems, where any delay tends to be further amplified by the accrued passenger loads encountered at stops downstream. This self-reinforcing mechanism, when combined with the multiple sources of disturbances of an urban environment, can lead to the problem of bus bunching. LÄS MER

7. 5. Design and assessment of legume-supported cropping systems

   Författare :Moritz Reckling; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Legumes provide high quality protein for food and feed as well as other ecosystem services, but it is still challenging to use them to meet the growing global demand for protein, partly because European farmers consider their cultivation unprofitable and risky. This thesis aims to design legume-supported cropping systems and assess their environmental and economic impacts along with their production risks in European agriculture. LÄS MER
