  1. 21. System Modeling Using Basis Functions and Application to Echo Cancelation

    Författare :Lester S.H. Ngia; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laguerre filters; Gauss-Newton algorithms; Levenberg-Marquard algorithms; room acoustics; separable nonlinear least-squares; adaptive filtering; off-line estimation; echo cancelation; on-line estimation; system modeling; neural net filters; Kautz filters; loudspeaker systems; steepest-descent algorithms; Hammerstein models;

    Sammanfattning : This thesis concerns modeling of linear and nonlinear dynamic systems, where the applied models can be described by basis function expansions. In the first part of the thesis, the investigated model (or filter) structures and parameter estimation algorithms are described. LÄS MER

  3. 22. Långhus i Gene : teori och praktik i rekonstruktion

    Författare :Lena Edblom; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Reconstruction; longhouse; Early Iron Age; Central Norrland; furnishing; room functions; fire; seat of honour; Christianisation; Icelandic sagas; Icelandic construction techniques; Arkeologi; Archaeology subjects; Arkeologiämnen; Archaeology; arkeologi;

    Sammanfattning : Under åren 1977–89 bedrev arkeologiska institutionen vid Umeå universitet en forskningsundersökning av en boplats från äldre järnålder på Genesmon i Själevad socken, norra Ångermanland. Under åren 1991–99 rekonstruerades delar av gården i Gene fornby, ett hundratal meter därifrån. LÄS MER

  4. 23. Ventilation and window opening in schools, Experiments and Analysis

    Författare :Birgitta Nordquist; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat exchanger efficiency; duct design; balancing; disturbance; tracer gas measurements; analytical model; window opening; single-sided ventilation; ventilation; schools; sensitivity analysis; Building construction; Byggnadsteknik;

    Sammanfattning : The objective of this thesis is to study the application of ventilation in schools buildings. A number of studies of the application of different forms of ventilation are presented. The main part of the thesis focuses on window opening in a classroom. Analytical models for calculation of the air change caused by window airing are proposed. LÄS MER

  5. 24. Acoustic Sound Source Localisation and Tracking : in Indoor Environments

    Författare :Anders Johansson; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Room acoustics; Speaker localisation; Tracking; State-space filter; Sequential Monte Carlo method; Particle filter;

    Sammanfattning : With advances in micro-electronic complexity and fabrication, sophisticated algorithms for source localisation and tracking can now be deployed in cost sensitive appliances for both consumer and commercial markets. As a result, such algorithms are becoming ubiquitous elements of contemporary communication, robotics and surveillance systems. LÄS MER

  7. 25. Drivers of customers' service experiences : a customer perspective on co-creation of restaurant services, focusing on interactions, processes and activities

    Författare :Ute Walter; Åsa Öström; Bo Edvardsson; Tore Strandvik; Örebro universitet; []
    Nyckelord :customer service experience; experience driver; dynamic; restaurant; co-creation; critical incident technique; phone encounters; experience room; servicescape; social interaction; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Culinary Arts and Meal Science; Måltidskunskap; Måltidskunskap; Culinary Arts and Meal Science;

    Sammanfattning : It is essential for service companies to understand how their customer service experiences are formed. This is especially important since service experiences are highly subjective and involve customers cognitively, emotionally and behaviorally. LÄS MER
