1. 21. Quantitative tissue classication with dual-energy computed tomography for radiation treatment planning evaluation and optimization of a new method

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Mattias Karlsson; [2010]
   Keywords : Röntgen; Medicine and Health Sciences;

   Abstract : A new method to extract mass density and elemental compositions of tissues from dual-energy computed tomography (DECT) scans is described and investigated. The method decomposes a tissue into proportions of two or three predened base materials and was proposed in 2008 by a research team at Linkoping University. READ MORE

3. 22. Analysis and Development of Error-Job Mapping and Scheduling for Network-on-Chips with Homogeneous Processors

   University essay from Institutionen för datavetenskap

   Author : Erik Karlsson; [2010]
   Keywords : NoC; Network-on-Chip; MPSoC; fault tolerance; fault-tolerant; job; mapping; scheduling; RRC; minimize; AET; efficient;

   Abstract : Due to increased complexity of today’s computer systems, which are manufactured in recent semiconductor technologies, and the fact that recent semiconductor technologies are more liable to soft errors (non-permanent errors) it is inherently difficult to ensure that the systems are and will remain error-free. Depending on the application, a soft error can have serious consequences for the system. READ MORE

4. 23. Equipment for measuring cosmic-ray effects on DRAM

   University essay from Institutionen för systemteknik

   Author : Per-Axel Jonsson; [2007]
   Keywords : DRAM; memory; SEU; single event upset; soft error; FPGA; cosmic radiation;

   Abstract : Nuclear particles hitting the silicon in a electronic device can cause a change in the data in a memory bit cell or in a flip-flop. The device is still working, but the data is corrupted and this is called a soft error. A soft error caused by a single nuclear particle is called a single event upset and is a growing problem.

5. 24. Hardware Accelerator for Duo-binary CTC decoding : Algorithm Selection, HW/SW Partitioning and FPGA Implementation

   University essay from Institutionen för systemteknik

   Author : Joakim Bjärmark; Marco Strandberg; [2006]
   Keywords : Error Correcting Codes; Turbo Codes; Decoding; Implementation; FPGA;

   Abstract : Wireless communication is always struggling with errors in the transmission. The digital data received from the radio channel is often erroneous due to thermal noise and fading. The error rate can be lowered by using higher transmission power or by using an effective error correcting code. READ MORE

6. 25. Evaluation of the Elekta Synergy concept for patient positioning in image guided radiotherapy

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Johan Renström; [2006]
   Keywords : Strålterapi; Medicine and Health Sciences;

   Abstract : Introduction: The Elekta Synergy machine for external beam radiation therapy is equipped with an x-ray tube for on-line kV imaging and correction of the patient setup. The system can provide both 2D and 3D data for image guided radiotherapy (IGRT). READ MORE
