1. 11. Communication quality : a conceptual approach focusing on classroom assistive listening devices

   Författare :Johan Odelius; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

   Sammanfattning : In a classroom an assistive listening device (ALD) is a system of external microphones that transmit sound from a sound source directly to students' hearing aids. An ALD can be a microphone close to the mouth which transmits a voice directly to listeners' hearing aids. LÄS MER

3. 12. Assessment of assistive technology : outcomes, costs and quality

   Författare :Ursula Hass; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Technology assessment aims at providing information about costs and effects, in order to support decision making and resource allocation. The purpose of this thesis is to, through empirical studies on assistive technologies, investigate the contribution of various kinds of outcome measures, and provide knowledge about outcomes, costs and quality of services.

4. 13. Passenger assessments of quality in local public transport- measurement, variability and planning implications

   Författare :Helena Sjöstrand; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passenger; public transport; quality; survey; Stated Preference; assessment; assignment; planning; Transportteknik; Transport technology; Road transport technology; Vägtransportteknik;

   Sammanfattning : The aim of this work was to get a more detailed basis for planning of local public transport. With more knowledge of how segments of travellers assess different parts of a journey, bus routes can be planned to fit either all passengers or selected groups better. LÄS MER

5. 14. On Enhancement and Quality Assessment of Audio and Video in Communication Systems

   Författare :Andreas Rossholm; Blekinge Tekniska Högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QoE; video quality assessment; video quality metric; multi-linear regression; artificial neural network; support vector machine; quality predictor; machine learning; temporal scaling; spatial scaling; video compression; deblocking filter; noise cancelling; synchronization; audio delay; video delay; GSM interference signal; noise cancellation; notch filtering;

   Sammanfattning : The use of audio and video communication has increased exponentially over the last decade and has gone from speech over GSM to HD resolution video conference between continents on mobile devices. As the use becomes more widespread the interest in delivering high quality media increases even on devices with limited resources. LÄS MER

7. 15. Uppföljning och utvärdering för förändring : pedagogisk dokumentation som grund för kontinuerlig verksamhetsutveckling och systematiskt kvalitetsarbete i förskolan

   Författare :Ingela Elfström; Gunilla Dahlberg; Gunnar Åsén; Agneta Linné; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; preschool; assessment; evaluation; pedagogical documentation; development of practice; an immanent perspective; förskola; uppföljning; utvärdering; pedagogisk dokumentation; utvecklingsarbete; immanent perspektiv; Early Childhood Education; förskoledidaktik;

   Sammanfattning : The purpose of the study is to examine, in relation to the curriculum for the Swedish preschool demands of assessment, evaluation and documentation what kind of knowledge that becomes possible through the use of pedagogical documentation, and how this knowledge answers to expectations of development of content, form and organisation of the early childhood educational context. Another purpose is to examine what a post-pragmatic perspective and an immanent idea of evaluation can imply for the two-folded task of the preschool: the societal reproduction of knowledge and the staging of possibilities for children’s own production of knowledge.
