1. 6. Reconfigurable-Hardware Accelerated Stream Aggregation

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

   Sammanfattning : 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. LÄS MER

3. 7. Forest-stream linkages : Experimental studies of foraging and growth of brown trout (Salmo trutta L)

   Författare :Pär Gustafsson; Eva Bergman; Larry Greenberg; John Armstrong; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brown trout; diet; growth; riparian zone; forest-stream linkages; terrestrial invertebrates; light; primary production; Biology; Biologi; Biology; Biologi;

   Sammanfattning : Riparian vegetation along streams and rivers affects the aquatic community in numerous ways and often operates as a link for energy flux between forest and streams. The studies presented in this licentiate thesis focus on light and terrestrial invertebrates, two factors influenced by riparian zone structure, which potentially affect stream ecosystems and thus also brown trout (Salmo trutta).

4. 8. Distributed stream ciphers

   Författare :Magnus Öberg; Ben Smeets; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Cryptographic operations are normally carried out by a single machine. Sometimes, however, this machine cannot be trusted completely. Threshold cryptography offers an alternative where the cryptographic operation is distributed to a group of machines in such a way that the key used in the cryptographic operation is not revealed to anyone.

5. 9. Grow with the flow : Hydrological controls of riparian vegetation in boreal stream networks

   Författare :Lenka Kuglerová; Roland Jansson; Hjalmar Laudon; Birgitta Malm-Renöfält; John Stella; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boreal forest; channelization; groundwater; Krycklan catchment; liverworts; mosses; riparian buffers; riparian vegetation; river restoration; species richness; stream network; stream size; vascular plants;

   Sammanfattning : What drives species diversity across landscapes is one of the most fundamental questions in ecology. Further, understanding the mechanisms underlying species diversity patterns is important not only for forming and challenging ecological theories but also essential for appropriate landscape management and effective nature conservation.

7. 10. Peakflow response of stream networks : implications of physical descriptions of streams and temporal change

   Författare :Anna Åkesson; Anders Wörman; Alberto Viglione; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Streamflow routing; peakflow predictions; parameterization; hydrological response; stage-dependency; flooded cross-sections; stream networks; backwater effects; temporal change; land use change; Civil and Architectural Engineering; Byggvetenskap;

   Sammanfattning : Through distributed stream network routing, it has quantitatively been shown that the relationship between flow travel time and discharge varies strongly nonlinearly with stream stage and with catchment-specific properties.Physically derived distributions of water travel times through a stream network were successfully used to parameterise the streamflow response function of a compartmental hydrological model.
