   Sammanfattning : Mammographic screening is an effective way to detect breast cancer. Early detection of breast cancer depends to a high degree on the adequacy of the mammogram from which the diagnosis is made. Today, most of the analysis of the mammogram is performed by radiologists. LÄS MER

3. 7. Image Reconstruction and Optical Flow Estimation on Image Sequences with Differently Exposed Frames

   Författare :Tomas Bengtsson; Chalmers tekniska högskola; []

   Sammanfattning : The main objective for digital image- and video camera systems is to reproduce a real-world scene in such a way that a high visual quality is obtained. A crucial aspect in this regard is, naturally, the quality of the hardware components of the camera device. There are, however, always some undesired limitations imposed by the sensor of the camera.

   Sammanfattning : New combustion engine principles increase the demands on feedback combustion control, at the same time economical considerations currently enforce the usage of low-end control hardware limiting implementation possibilities. Significant development is simultaneously and continuously carried out within the field of Field Programmable Gate Arrays (FPGAs). LÄS MER

5. 9. Underactuated mechanical systems : Contributions to trajectory planning, analysis, and control

   Författare :Pedro La Hera; Anton Shiriaev; Ambarish Goswami; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underactuated mechanical systems; mechanical systems with impacts; trajectory planning; periodic trajectories; orbital stabilization; walking robots; virtual holonomic constraints; transverse linearization; Automatic control; Reglerteknik; Automatic Control; reglerteknik;

   Sammanfattning : Nature and its variety of motion forms have inspired new robot designs with inherentunderactuated dynamics. The fundamental characteristic of these controlled mechanicalsystems, called underactuated, is to have the number of actuators less than the number ofdegrees of freedom. LÄS MER

7. 10. Complex Cavity Analysis : Analytical Fluid-Power Models Using CAD Information

   Författare :Magnus Sethson; Richard T. Burton; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis covers different methods of topology search for making time-domain simulation models based on geometric information. The application is in the field of fluid-power. Automatic methods for extracting simulation models from CAD data are presented. LÄS MER
