1. 1. Algorithms for aggregate information extraction from sequences

   Författare :Fredrik Bengtsson; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

   Sammanfattning : In this thesis, we propose efficient algorithms for aggregate information extraction from sequences and multidimensional arrays. The algorithms proposed are applicable in several important areas, including large databases and DNA sequence segmentation. LÄS MER

3. 2. Efficient aggregate queries on data cubes

   Författare :Fredrik Bengtsson; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

   Sammanfattning : As computers are developing rapidly and become more available to the modern information society, the possibility and ability to handle large data sets in database applications increases. The demand for efficient algorithmic solutions to process huge amounts of information increases as the data sets become larger. LÄS MER

4. 3. The Cerebello-Olivary Feedback System

   Författare :Fredrik Bengtsson; Neurofysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neurofysiologi; neurophysiology; Neurology; neuropsychology; Fysiologi; Physiology; Cerebellum; Purkinje cell; Inferior olive; Neurologi; Nucleo-olivary; Climbing fibre.; Deep cerebellar nuclei;

   Sammanfattning : The pathway from the deep cerebellar nuclei to the inferior olive, the nucleo-olivary pathway, is known to be inhibitory. The physiological and temporal properties, as well as the localisation, of the nucleo-olivary pathway were characterised in the decerebrate ferret. LÄS MER

5. 4. Development and evaluation of methods for control and modelling of multiple-input multiple-output systems

   Författare :Fredrik Bengtsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Input-output scaling; Modeling; Fiber length; Tensile Index; Hold-input; Decentralized control; Gramian based measures; Delays; LQG control; TMP; Uncertain data sets; Unreliable communication links; MIMO systems; Control configuration selection; Linear regression; Freeness; Shives; CTMP;

   Sammanfattning : In control, a common type of system is the multiple-input multiple-output (MIMO) system, where the same input may affect multiple outputs, or conversely, the same output is affected by multiple inputs. In this thesis two methods for controlling MIMO systems are examined, namely linear quadratic Gaussian (LQG) control and decentralized control, and some of the difficulties associated with them.
