  1. 1. Techniques to Reduce Inefficiencies in Hardware Transactional Memory Systems

    Författare :Mridha Mohammad Waliullah; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intermediate checkpoint; conflicting address prediction; Bloom filter; conflict resolution; multiprocessor; speculative buffer overflow; parallel programming; 5C model for cache-misses; transactional memory; conflict classification; starvation;

    Sammanfattning : The recent trend of multicore CPUs pushes for major changes in software development. Traditional single-threaded applications can no longer get a sustainable performance boost from this new generation of CPUs that consist of multiple processors (cores). LÄS MER

  3. 2. Social Networks and Privacy

    Författare :Oleksandr Bodriagov; Sonja Buchegger; Melek Ӧnen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; social networks; privacy; decentralized; encryption-based access control; Computer Science; Datalogi;

    Sammanfattning : Centralized online social networks pose a threat to their users’ privacy as social network providers have unlimited access to users’ data. Decentralized social networks address this problem by getting rid of the provider and giving control to the users themselves, meaning that only the end-users themselves should be able to control access of other parties to their data.

  4. 3. Factors controlling pelagic communities of freshwater ciliates and heliozoans

    Författare :Ulrika Stensdotter-Blomberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; ciliates; heliozoans; freshwater; nutrients; predation; microbial food web; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; limnologi; Limnology;

    Sammanfattning : Ciliate diversity and seasonal succession were studied during two years in oligotrophic,acidic Lake Njupfatet. Maximum ciliate abundance occurred shortly after ice-out. After thefirst year, the lake was neutralised by liming. Liming caused changes in the bacterioplanktonand phytoplankton communities, but no change in ciliate diversity. LÄS MER

  5. 4. Functional diversity of zooplankton in marine food webs : Integrating DNA metabarcoding and network modeling

    Författare :Andreas Novotny; Monika Winder; Catherine Legrand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plankton; Food-Webs; DNA metabarcoding; Marine; Baltic Sea; Marine Ecology; marin ekologi;

    Sammanfattning : The oceans are important regulators of the Earth’s climate system by sequestering carbon from the atmosphere taken up by primary producers. Zooplankton, including protozoans and metazoans of different phyla and size classes, occupies several trophic niches and regulates energy flow between primary producers and fish. LÄS MER

  7. 5. Vector Symbolic Architectures and their applications : Computing with random vectors in a hyperdimensional space

    Författare :Denis Kleyko; Evgeny Osipov; Mika Laiho; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : The main focus of this thesis lies in a rather narrow subfield of Artificial Intelligence. As any beloved child, it has many names. The most common ones are Vector Symbolic Architectures and Hyperdimensional Computing. LÄS MER
