1. 1. A Signal Processing Approach to Practical Neurophysiology : A Search for Improved Methods in Clinical Routine and Research

   Författare :Björn Hammarberg; Dick Stegeman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; matched filter; asynchronous detection; Kalman filter; initialization; MHT; Wiener deconvolution; line source model; electromyography; needle EMG; motor unit potential; MUAP; mean fiber concentration; jitter; microneurography; C-fiber; spike sorting; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

   Sammanfattning : Signal processing within the neurophysiological field is challenging and requires short processing time and reliable results. In this thesis, three main problems are considered.First, a modified line source model for simulation of muscle action potentials (APs) is presented. LÄS MER

3. 2. On Robotic Work-Space Sensing and Control

   Författare :Magnus Linderoth; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; computer vision; color constancy; motion blur; filter initialization; visual tracking; on-line trajectory generation; ball-catching robot; force control; robotic assembly; force estimation; perception-action capabilities.;

   Sammanfattning : Industrial robots are fast and accurate when working with known objects at precise locations in well-structured manufacturing environments, as done in the classical automation setting. In one sense, limited use of sensors leaves robots blind and numb, unaware of what is happening in their surroundings. LÄS MER

4. 3. Robotic Work-Space Sensing and Control

   Författare :Magnus Linderoth; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assembly; force control; on-line trajectory generation; filter initialization; visual tracking; Robotics; computer vision; cooperating robots;

   Sammanfattning : Industrial robots are traditionally programmed using only the internal joint position sensors, in a sense leaving the robot blind and numb. Using external sensors, such as cameras and force sensors, allows the robot to detect the existence and position of objects in an unstructured environment, and to handle contact situations not possible using only position control.

5. 4. Some Results on Distinguishing Attacks on Stream Ciphers

   Författare :Håkan Englund; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; correlation attack; irregularly clocked filter generator; distinguishing attacks; Stream ciphers; filter generator; Pomaranch; Dragon; LILI-128; LILI-II;

   Sammanfattning : Stream ciphers are cryptographic primitives that are used to ensure the privacy of a message that is sent over a digital communication channel. In this thesis we will present new cryptanalytic results for several stream ciphers. LÄS MER

7. 5. Recursive black-box identification of nonlinear state-space ODE models

   Författare :Linda Brus; Bengt Carlsson; Torbjörn Wigren; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Nonlinear system identification methods is a topic that has been gaining interest over the last years. One reason is the many application areas in controller design and system development. However, the problem of modeling nonlinear systems is complex and finding a general method that can be used for many different applications is difficult. LÄS MER
