   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Implementation; Burrows-Wheeler Transform; Sliding Window; Suffix Sorting; Text Compression; Algorithms; Suffix Tree; Systems engineering; computer technology; Data- och systemvetenskap;

   Abstract : This doctoral dissertation presents a range of results concerning efficient algorithms and data structures for string processing, including several schemes contributing to sequential data compression. It comprises both theoretic results and practical implementations. READ MORE

4. 2. Real-time data stream clustering over sliding windows

   Author : Sobhan Badiozamany; Tore Risch; Tamer Özsu; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data streaming; Sliding windows; Clustering; ; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Abstract : In many applications, e.g. urban traffic monitoring, stock trading, and industrial sensor data monitoring, clustering algorithms are applied on data streams in real-time to find current patterns. Here, sliding windows are commonly used as they capture concept drift. READ MORE

5. 3. Finite-Length Scaling Laws for Spatially-Coupled LDPC Codes

   Author : Roman Sokolovskii; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; belief propagation decoding; spatially-coupled LDPC codes; window decoding; codes-on-graphs; finite-length code performance;

   Abstract : This thesis concerns predicting the finite-length error-correcting performance of spatially-coupled low-density parity-check (SC-LDPC) code ensembles over the binary erasure channel. SC-LDPC codes are a very powerful class of codes; their use in practical communication systems, however, requires the system designer to specify a considerable number of code and decoder parameters, all of which affect both the code’s error-correcting capability and the system’s memory, energy, and latency requirements.

6. 4. Reconfigurable-Hardware Accelerated Stream Aggregation

   Author : Prajith Ramakrishnan Geethakumari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stream; Reconfigurable Computing; Aggregation; Dataflow; FPGA; Memory Hierarchy; Compression;

   Abstract : High throughput and low latency stream aggregation is essential for many applications that analyze massive volumes of data in real-time. Incoming data need to be stored in a single sliding-window before processing, in cases where incremental aggregations are wasteful or not possible at all. READ MORE

7. 5. Synthesis, Characterization, and Evaluation of Ag-based Electrical Contact Materials

   Author : Fang Mao; Ulf Jansson; Mikael Olsson; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrical contact; bulk; coating; Ag-based alloys; Ag-based delafossite; AgI; graphene; graphene oxide; combinatorial material science; dc magnetron sputtering; friction; wear; hardness; contact resistance;

   Abstract : Ag is a widely used electrical contact material due to its excellent electrical properties. The problems with Ag are that it is soft and has poor tribological properties (high friction and wear in Ag/Ag sliding contacts). READ MORE
