1. 21. The neurophysiology of working memory : functional mapping of the human brain with positron emission tomography

   Författare :Torkel Klingberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Working memory (WM) refers to the retention, or keeping on-line, of information over short periods of time. WM is thought to be important for a variety of cognitive functions, including problem solving, learning and reading. LÄS MER

   Författare :Muhammad Ramzan; Rajeev Ahuja; S. K. Saxena; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DFT; Hydrogen storage; Rechargeable batteries; Amorphization; Electronic structure; Crystal strcuture; Molecular dynamics; Diffusion; Intercalation voltage; High pressure; MAX phases; Mechanical properties; Optical properties; Phase change memory; Spintronics; Magnetism; Correlation effects; Band structure; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : The search for alternate and renewable energy resources as well as the efficient use of energy and development of such systems that can help to save the energy consumption is needed because of exponential growth in world population, limited conventional fossil fuel resources, and to meet the increasing demand of clean and environment friendly substitutes. Hydrogen being the simplest, most abundant and clean energy carrier has the potential to fulfill some of these requirements provided the development of efficient, safe and durable systems for its production, storage and usage.

4. 23. Interframe Quantization for Noisy Channels

   Författare :Jan Lindén; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The demand for efficient transmission and storage of, for example, speech signals poses high requirements on the development of signal compression techniques. This thesis deals with vector quantization (VQ) which is a powerful technique for signal compression. LÄS MER

5. 24. Techniques to Cancel Execution Early to Improve Processor Efficiency

   Författare :Mafijul Islam; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; processor design; energy-efficiency; narrow-width cache; instruction reuse; zero-value cache; resource-efficient; narrow-width load; complexity-effective; small value locality; register file cache; frequent value locality; trivial instruction; silent load; high-performance; zero load;

   Sammanfattning : The evolution of computer systems to continuously improve execution efficiency has traditionally embraced various approaches across microprocessor generations. Unfortunately, contemporary processors still suffer from several inefficiencies although they offer an unprecedented level of computing capabilities. LÄS MER

7. 25. Multi-LSTM Acceleration and CNN Fault Tolerance

   Författare :Stefano Ribes; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compression; SVD; LSTMs; CNNs; Fault Tolerance; Machine Learning; FPGA; Roofline Model; HLS; Caffe;

   Sammanfattning : This thesis addresses the following two problems related to the field of Machine Learning: the acceleration of multiple Long Short Term Memory (LSTM) models on FPGAs and the fault tolerance of compressed Convolutional Neural Networks (CNN). LSTMs represent an effective solution to capture long-term dependencies in sequential data, like sentences in Natural Language Processing applications, video frames in Scene Labeling tasks or temporal series in Time Series Forecasting.
