  1. 1. Forest edges in boreal landscapes - factors affecting edge influence

    Author : Ulrika Jansson; Per-Anders Esseen; Mats Nilsson; Timo Kuuluvainen; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; aerial photographs; edge contrast; edge density; edge length; fetch size; forest fragmentation; lichen growth; line intersect sampling; pendulous lichen; photo interpretation; skogskant; flygbild; kantlängd; lav; Terrestrial ecology; Terrestisk ekologi; ekologisk botanik; Ecological Botany;

    Abstract : The boreal forest in Fennoscandia has been subjected to major loss and fragmentation of natural forests due to intensive forestry. This has resulted in that forest edges are now abundant and important landscape features. Edges have documented effects on the structure, function and biodiversity in forests. READ MORE

  2. 2. Primary Marine Aerosol Production : Studies using bubble-bursting experiments

    Author : Kim Hultin; Douglas Nilsson; Radovan Krejci; Ian Cousins; Åke Hagström; Erik Swietlicki; Stockholms universitet; []
    Keywords : sea spray; water temperature; dissolved oxygen; photosynthesis; bacterial emissions; V-TDMA; mixing state; eddy covariance; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Aerosol particles affect the Earth’s climate, although their impact is associated with large uncertainties. Primary marine aerosol represents a significant fraction of the global aerosol budget considering the Earth’s 70-percentage coverage by oceans. READ MORE

  3. 3. Efficient methods for application performance analysis

    Author : David Eklöv; Erik Hagersten; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Abstract : To reduce latency and increase bandwidth to memory, modern microprocessors are designed with deep memory hierarchies including several levels of caches. For such microprocessors, the service time for fetching data from off-chip memory is about two orders of magnitude longer than fetching data from the level-one cache. READ MORE

  4. 4. Distributed k-ary System: Algorithms for Distributed Hash Tables

    Author : Ali Ghodsi; Seif Haridi; Alexander Reinefeld; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; distributed hash tables; structured overlay networks; distributed algorithms; distributed systems; group communication; replication; Computer science; Datavetenskap;

    Abstract : This dissertation presents algorithms for data structures called distributed hash tables (DHT) or structured overlay networks, which are used to build scalable self-managing distributed systems. The provided algorithms guarantee lookup consistency in the presence of dynamism: they guarantee consistent lookup results in the presence of nodes joining and leaving. READ MORE

  5. 5. Predicting Ecosystem Response from Pollution in Baltic Archipelago areas using Mass-balance Modelling

    Author : Olof Magnus Karlsson; Andreas Bryhn; Lars Håkanson; Per Jonsson; Mikael Malmaeus; Kristoffer Naes; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; archipelagos; aquatic ecosystems mass-balance modelling; sediment-water dynamics; phosphorus; dioxins; PCDD Fs; Other earth sciences; Övrig geovetenskap; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Abstract : Baltic archipelago areas have high nature values despite being polluted from various antrophogenic activities within the Baltic Sea catchment area and from long-range transport of airborne substances. The discovery of environmental problems in the Baltic Sea in the 1960s led to countermeasures that gradually gave results in reducing the toxic pollution, e. READ MORE
