1. 16. Testing and implementation of a backlash detection algorithm

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Max Haventon; Jakob Öberg; [2008]
   Keywords : Technology and Engineering;

   Abstract : Backlash is a well documented and rather common non-linearity which is present in most mechanical and hydraulic systems. The amount of backlash varies depending on the dynamics of the system, for example a gear box in a car needs some space for heat expansion and consequently some amount of backlash in order to function.

3. 17. Evaluation of Geometric Accuracy and Image Quality of an On-Board Imager (OBI)

   University essay from Medicinsk strålningsfysik (tills m KI)

   Author : Milos Djordjevic; [2007]
   Keywords : Image-guided radiotherapy; Cone-beam CT; OBI; Quality Assurance;

   Abstract : In this project several tests were performed to evaluate the performance of an On-Board Imager® (OBI) mounted on a clinical linear accelerator. The measurements were divided into three parts; geometric accuracy, image registration and couch shift accuracy, and image quality. READ MORE

4. 18. Crack Detection using Non-linear and Dissipative Acoustics

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Daniel Carldén; Daniel Thuresson; [1998]
   Keywords : Non-linear acoustics; Non-linear parameter; Burger s equation; Bessel-Fubini; Fay; Mendousse; Hedberg; Non-destructive testing NDT ; Non-destructive Evaluation NDE ; crack detection.;

   Abstract : A theoretical model for identification of acoustical non-linearity using Burger's equation was implemented in a MATLAB program. The program identified both the non-linearity parameter and the distance from the signal source. Tests were performed in order to verify the theories. READ MORE
