1. 1. Extensible Compiler Construction

   Författare :Torbjörn Ekman; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerical analysis; Computer science; attribute grammars; extensible compilers; context-sensitive transformations; declarative object-oriented programming; kontroll; system; numerisk analys; Datalogi; control; systems;

   Sammanfattning : Processing of programs is a core area in computer science. A compiler that translates source text to machine language is the most well-known kind of tool in this area, but there are numerous other kinds of related applications: source-to-source translators, refactoring tools, reengineering tools, metrics tools, consistency checkers, etc. LÄS MER

3. 2. Prediction of Mobile Radio Channels : Modeling and Design

   Författare :Torbjörn Ekman; Rodney Vaughan; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; mobile radio channel; fading; channel model; channel estimation; channel prediction; power prediction; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

   Sammanfattning : Prediction of the rapidly fading envelope of a mobile radio channel enables a number of capacity improving techniques like fast resource allocation and fast link adaptation. This thesis deals with linear prediction of the complex impulse response of a channel and unbiased quadratic prediction of the power. LÄS MER

4. 3. Rewritable Reference Attributed Grammars - design, implementation, and applications

   Författare :Torbjörn Ekman; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis presents an object-oriented technique for rewriting abstract syntax trees in order to simplify compilation. The technique, Rewritable Reference Attributed Grammars (ReRAGs), is completely declarative and supports both rewrites and computations by means of attributes. LÄS MER

5. 4. Important Factors for Accurate Scale-Resolving Simulations of Automotive Aerodynamics

   Författare :Petter Ekman; Matts Karlsson; Torbjörn Virdung; Roland Gårdhagen; Adrian Gaylard; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Road transports are responsible for almost 18 % of the greenhouse gas emission in Europe and are today the leading cause of air pollution in cities. Aerodynamic resistance has a significant effect on fuel consumption and hence the emission of vehicles. LÄS MER

7. 5. From games to news : Creating an engagement model for digital local news

   Författare :Torbjörn Svensson; Lissa Holloway-Attaway; Stefan Ekman; Mikael Berndtsson; Pedro F. Campos; Högskolan i Skövde; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; GAME Research Group; GAME Research Group;

   Sammanfattning : The transition of local news from the analog, printed format to a digital format, fit for our increasingly digitized media technology society, has not been as straight-forward as was imagined at the dawning of the World Wide Web. Newspapers, in particular local newspapers, were quite fast in trying to adapt to the new technology platform and put their content on the web. LÄS MER
