1. 1. Computer-based detection of cardiac arrhythmias : methods and systems

   Författare :Mats-Erik Nygårds; Linköpings universitet; []
   Nyckelord :Arrhythmia; monitoring; feature extraction; QRS delineation; power spectrum; ventricular fibrillation; MEDICINE; MEDICIN;

   Sammanfattning : The aim of this study was to develop methods and systems which could improve the accuracy or arrhythmia monitoring and analysis of long-term ECGs and eliminate or reduce the need for continuous visual ECG screening. The detection of arrhythmias was based on an automatic classification of heart beats, using waveform features obtained from a basis signals representation. LÄS MER

   Författare :Håkan Petersson; Robert Bjärnemo; Damien Motte; Kjell Andersson; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer-Based Design Analysis; Engineering Design process; Template; and Template-Based Design Analysis; Datorbaserad konstruktionsanalys; Konstruktionsprocess; undersökning; beräkningsstöd samt minskade ledtider; MallBaserad KonstruktionsAnalys; Computer-Based Design Analysis; Engineering Design process; Template; and Template-Based Design Analysis;

   Sammanfattning : The current trend in industry to encourage engineering designers to take an active part in the analysis of their own design solutions is apparent in many companies today, domestically as well as abroad.From a research project with the objective to develop a computer-based design system for the design of lightweight grippers, one of the major difficulties was to overcome the system users’ lack of knowledge and experience in the design of lightweight structures and Computer-Based Design Analysis (CBDA).

4. 3. Dialogues on the Net - Power structures in asynchronous discussions in the context of a web based teacher training course

   Författare :Annette Johnsson; Utbildningsvetenskap; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; minority; cultural background; sex; ethnicity; gender; age; socio-economic; dialogicity; web based; computer based; CMC; net based; asynchronous; CSCL; teacher education; power structures; dialogues; Group work; team work; symbolic capital; group work;

   Sammanfattning : The general aim of this thesis is to investigate the interaction processes that occur in group dialogues when teacher students work in small groups, using net based asynchronous dialogues to solve a problem in the area of environmental sustainability. More specifically, the interest is to determine whether students’ net based dialogues give rise to patterns of dominance/subordination similar to those observed in face-to-face situations. LÄS MER

5. 4. Computer-based speech therapy using visual feedback with focus on children with profound hearing impairments

   Författare :Anne-Marie Öster; David House; James Mahshie; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Speech technology; hearing-imparment; speech therapy; visual feedback; second language learning; computer-based speech training; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : This thesis presents work in the area of computer-based speech therapy using different types of visual feedback to replace the auditory feedback channel. The study includes diagnostic assessment methods prior to therapy, type of therapy design, and type of visual feedback for different users during different stages of therapy for increasing the efficiency.
