  2. 1. Group-Sparse Regression : With Applications in Spectral Analysis and Audio Signal Processing

    Author : Ted Kronvall; Statistical Signal Processing Group; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sparse regression; group-sparsity; statistical modeling; regularization; hyperparameter-selection; spectral analysis; audio signal processing; classification; localization; multi-pitch estimation; chroma; convex optimization; ADMM; cyclic coordinate descent; proximal gradient;

    Abstract : This doctorate thesis focuses on sparse regression, a statistical modeling tool for selecting valuable predictors in underdetermined linear models. By imposing different constraints on the structure of the variable vector in the regression problem, one obtains estimates which have sparse supports, i.e. READ MORE

  4. 2. Applications of Microwave Heating of Foods

    Author : Birgitta Raaholt; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling of microwave heating; microwave-assisted HTST processing; product quality.; heat transfer; microwave heating; microwave oven; heating uniformity; microwave cavity; tubular microwave in-flow processing;

    Abstract : AbstractMicrowave heating of foods offers rapid and flexible heating both for consumer and industrial applications, with several advantages, such as reduced processing time (due to volumetric heating and reduced coming-up times (heating time required to reach the desired target temperature), selective heating, increased process flexibility and efficient heating (volumetric heating of the food does not require heating of a surrounding medium or package). However, successful installations requireknowledge in process design. READ MORE

  5. 3. Advances in sensor-controlled robotics : distributed multi-sensor data processing and the Linköping hand

    Author : Hans Odeberg; Linköpings universitet; []
    Keywords : Robotics; Sensor Fusion; Signal Processing;

    Abstract : Industrial robots are moronic machines capable only of mere point-to-point movements. If parts are slightly misplaced, or out of tolerance, smashup will result. To adapt the robot to its environment, sensors may be used. This will in turn cause new problems: which sensors should be used, how combine data from several disparate sources, etc. READ MORE

  6. 4. Coincidences and Paranormal Belief

    Author : Gergö Hadlaczky; Joakim Westerlund; Henry Montgomery; Peter Brugger; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Coincidences; surprise; paranormal belief; parapsychology; telepathy; associative processing; probabilistic reasoning; Ganzfeld; associative learning; automatic processing; controlled processing; Psychology; psykologi;

    Abstract : In this thesis it is argued that coincidences play an important role in the formation of belief, including belief in the paranormal. Three papers are presented. READ MORE

  7. 5. Low-Cost Navigation Systems : A Study of Four Problems

    Author : Isaac Skog; Peter Händel; Fredrik Gustafsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Navigation; Inertial Navigation; Pedestrian Navigation; Inertial Measurement Unit; Time Synchronization; Signal processing; Signalbehandling;

    Abstract : Today the area of high-cost and high-performance navigation for vehicles is a well-developed field. The challenge now is to develop high-performance navigation systems using low-cost sensortechnology. READ MORE
