  1. 11. On low-complexity frequency selective digital filters and filter banks

    Författare :Linnea Rosenbaum; Håkan Johansson; Tapio Saramäki; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital filters; filter banks; modulated; FRM; Electronics; Elektronik;

    Sammanfattning : En filterbank består av flera filter som arbetar tillsammans för att dela upp en signal i olika frekvensband. De kan också användas för att slå ihop signaler separerade i frekvensplanet till en enda. Sedan tidigt 70-tal har man lärt sig att designa förlustfria filterbankar som alltså inte introducerar några som helst fel i systemet. LÄS MER

  3. 12. Design of Programmable Baseband Processors

    Sammanfattning : The world of wireless communications is under constant change. Radio standards evolve and new standards emerge. More and more functionality is put into wireless terminals. E. LÄS MER

  4. 13. Home care communication : moving beyond the surface

    Författare :Jessica Höglander; Inger K. Holmström; Jakob Håkansson Eklund; Annelie J. Sundler; Bjöörn Fossum; Mälardalens högskola; []
    Nyckelord :communication; home care services; nursing staff; older persons; person-centred care; RIAS; VR-CoDES; Care Sciences; vårdvetenskap;

    Sammanfattning : Communication is an essential part of care and human interaction. While communication within care entails both task-focused and socio-emotional elements, nurses are sometimes perceived as too task-focused. When in need of care, older persons want to be perceived and treated as individuals – to feel involved. LÄS MER

  5. 14. Babble, grunts, and words : a study of phonetic shape and functional use in the beginnings of language

    Författare :Liselotte Roug-Hellichius; Florien J. Koopmansvan Beinum; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Phonetics; Fonetik; Phonetics; fonetik;

    Sammanfattning : The present study follows in the tradition of those seeking to understand linguistic behavior from a cognitive and socio-biological perspective (Bates, Benigni, Bretherton, Camaioni and Volterra 1979, Lindblom 1992, Hauser 1996) by tracing the development of a non-linguistic vocal behavior in relation to communicative and early lexical advances. More specifically the study focuses on the occurrence of what are termed ìcommunicative gruntsî and their functional relationship to adult based word use in one Swedish boy from 11 to 19 months of age.

  7. 15. Flexible Scheduling for Media Processing in Resource Constrained Real-Time Systems

    Författare :Damir Isovic; Gerhard Fohler; Sanjoy Baruah; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : The MPEG-2 standard for video coding is predominant in consumer electronics for DVD players, digital satellite receivers, and TVs today. MPEG-2 processing puts high demands on audio/video quality, which is achieved by continuous and synchronized playout without interrupts. At the same time, there are restrictions on the storage media, e.g. LÄS MER
