2. 1. Floating-Point Analog-to-Digital Converter

   Author : Johan Piper; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; matching; binary weighting; dynamic range; resolution; distortion; pipeline; A D-converter; floating-point; Elektronik och elektroteknik;

   Abstract : To deal with the wide dynamic rage necessary for a radio receiver or corresponding applications, but to avoid impractically high resolution at high data rates, the approach of using a floating-point analog-to-digital converter (FP-ADC) has been investigated. This approach de-links the dynamic range with the resolution, and a very wide dynamic range can be achieved by an ADC with a moderate resolution. READ MORE

4. 2. Verification Based Failure Detection for Real-Time Java and Floating-Point Computations

   Author : Gabriele Paganelli; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Debugging; Floating-Point; Formal Methods; Testing; Real-Time Java; Coverage; Satisfiability Modulo Theories; Certification; Formal Specification;

   Abstract : To err is human, and machines help us avoiding errors. This thesis presents two ways, based on verification technology, to prevent failures.Safety critical Real-Time Java applications usually need a certification. Tests fulfilling specific coverage criteria can be part of such certification, like in the DO-178 standard. READ MORE

5. 3. Numerical Modelling and Mechanical Studies on a Point Absorber Type Wave Energy Converter

   Author : Yue Hong; Rafael Waters; Mikael Eriksson; Cecilia Boström; Jørgen Hals Todalshaug; Uppsala universitet; []
   Keywords : linear generator; point absorber; numerical modelling; power production; optimal damping; Teknisk fysik; Engineering Science;

   Abstract : Oceans cover two thirds of the Earth’s surface and the energy potential of ocean waves as a renewable energy source is huge. It would therefore be a tremendous achievement if the vast mechanical energy in waves was converted into a form of energy that could be used successfully by society. READ MORE

6. 4. Optimization of Point Absorber Wave Energy Parks

   Author : Marianna Giassi; Malin Göteman; Jens Peter Kofoed; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave energy arrays; genetic algorithm; optimization; WEC; hydrodynamic interaction; Engineering Science; Teknisk fysik;

   Abstract : Renewable energies are believed to play the key role in assuring a future of sustainable energy supply and low carbon emissions. Particularly, this thesis focus on wave energy, which is created by extracting the power stored in the waves of the oceans. READ MORE

7. 5. An Automated and Controlled Numerical Precision Reduction Framework for GPUs

   Author : Alexandra Angerd; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microarchitecture; Floating-Point Precision; Approximate Computing; Register File; GPU;

   Abstract : Reducing the precision of floating-point values is an effective approach to achieve higher performance as well as higher energy-efficiency. This is especially true for GPUs, since many of its common tasks are inherently insensitive to precision-reduction. READ MORE
