1. 1. A Data-Driven Approach to Remote Fault Diagnosis of Heavy-duty Machines

   Författare :Tomas Olsson; Peter Funk; Amy Loutfi; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

   Sammanfattning : Heavy-duty machines are equipment constructed for working under rough conditions and their design is meant to withstand heavy workloads. However, the last decades technical development in cheap electronically components have lead to an increase of electrical systems in traditionally mainly mechanical systems of heavy-duty machines.

3. 2. Bootstrapping and decentralizing recommender systems

   Författare :Tomas Olsson; Arne Andersson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Computing Science;

   Sammanfattning : This thesis consists of three papers on recommender systems.The first paper addresses the problem of making decentralized recommendations using a peer-to-peer architecture. Collaborating recommender agents are connected into a network of neighbors that exchange user recommendations to find new items to recommend. LÄS MER

4. 3. Development and Characterization of a Global Brain Ischemia Model in the Mouse -A Genetic and Pharmacological Approach

   Författare :Tomas Olsson; Neuroinflammation; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurofysiologi; neuropsykologi; Neurologi; neuropsychology; Neurology; global; hypothermia; hsp70; receptor; adenosine A1; NMDA; cystatin C; cell death; hippocampus; Brain; ischemia; neurophysiology;

   Sammanfattning : Brain ischemia is a major cause of death and morbidity in the industrialized countries. It is mainly caused by stroke, but may also be the consequence of successful cardiopulmonary resuscitation in victims of cardiac arrest, known as transient global ischemia. LÄS MER

5. 4. Feedback Control and Sensor Fusion of Vision and Force

   Författare :Tomas Olsson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor based robot control; Visual tracking; visual servoing; resource optimization; Kalman filter;

   Sammanfattning : This thesis deals with feedback control using two different sensor types, force sensors and cameras. In many tasks robotics compliance is required in order to avoid damage to the workpiece. Force and vision are the most useful sensing capabilities for a robot system operating in an unknown or uncalibrated environment. LÄS MER

7. 5. High-Speed Vision and Force Feedback for Motion-Controlled Industrial Manipulators

   Författare :Tomas Olsson; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Force vision control; Visual tracking; Visual servoing; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : Over the last decades, both force sensors and cameras have emerged as useful sensors for different applications in robotics. This thesis considers a number of dynamic visual tracking and control problems, as well as the integration of these techniques with contact force control. LÄS MER
