   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active sound field control; room acoustics; reverberation enhancement; listening tests; subjective effects; sound-reinforcement; feedback systems; feedback control; computer modelling of acoustics in enclosures; modulation; electro acoustics; time-varying filters;

   Sammanfattning : The analysis of electroacoustic systems for reverberation enhancement in auditoria is the topic of this thesis. Such systems have been developed since the 50's and been commercially available since then as well. During the 80's several new system ideas have been presented but there are still some open questions that are addressed here. LÄS MER

5. 24. SiC based field effect sensors and sensor systems for combustion control applications

   Sammanfattning : Increasing oil prices and concerns about global warming have reinforced the interest in biofuels for domestic and district heating, most commonly through combustion of solid biomass like wood logs, hog fuel and pellets. Combustion at non-optimal conditions can, however, lead to substantial emissions of noxious compounds like unburned hydrocarbons, carbon monoxide, and nitrogen oxides as well as the generation of soot.

   Sammanfattning : In the curriculum for the subject of Swedish reading of literary texts is justified by ideas that literary reading will make the student learn more about the environment in which he/she lives, about herself/himself, as well as about others. It is well stated by previous research that what readings that is required and formulated in, for example, assignments or book talk, is important in how the text is discerned by the reader. LÄS MER
