1. 1. Online engineering : On the nature of open computational systems

   Författare :Martin Fredriksson; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Online Engineering; open computational systems;

   Sammanfattning : Computing has evolved from isolated machines, providing calculative support of applications, toward communication networks that provide functional support to groups of people and embedded systems. Perhaps, one of the most compelling feature and benefit of computers is their overwhelming computing efficiency. LÄS MER

3. 2. Human Interactions on Online Social Media : Collecting and Analyzing Social Interaction Networks

   Författare :Fredrik Erlandsson; Johnson Henric; Martin Boldt; Piotr Bródka; S. Felix Wu; Sune Lehmann; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Social Media; Social Networks; Crawling; Complex Networks; Information Cascade; Seed Selection; Privacy;

   Sammanfattning : Online social media, such as Facebook, Twitter, and LinkedIn, provides users with services that enable them to interact both globally and instantly. The nature of social media interactions follows a constantly growing pattern that requires selection mechanisms to find and analyze interesting data. LÄS MER

4. 3. Privacy Issues in Decentralized Online Social Networks and other Decentralized Systems

   Författare :Benjamin Greschbach; Sonja Buchegger; Melek Önen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Privacy; Online Social Networks; Decentralized Online Social Networks; Computer Science; Datalogi;

   Sammanfattning : Popular Online Social Networks (OSNs), such as Facebook or Twitter, are logically centralized systems. The massive information aggregation of sensitive personal data at the central providers of these services is an inherent threat to the privacy of the users. LÄS MER

5. 4. Online Learning for Energy Efficient Navigation in Stochastic Transport Networks

   Författare :Niklas Åkerblom; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Thompson Sampling; Online Minimax Path Problem; Multi-Armed Bandits; Online Learning; Online Shortest Path Problem; Machine Learning; Combinatorial Semi-Bandits; Energy Efficient Navigation;

   Sammanfattning : Reducing the dependence on fossil fuels in the transport sector is crucial to have a realistic chance of halting climate change. The automotive industry is, therefore, transitioning towards an electrified future at an unprecedented pace. LÄS MER

7. 5. Global functional association network inference and crosstalk analysis for pathway annotation

   Författare :Christoph Ogris; Erik Sonnhammer; Alfonso Valencia; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological networks; genome wide functional association networks; global gene association networks; gene networks; protein networks; functional association; functional coupling; network biology pathway analysis; pathway annotation; pathway enrichment; network-based enrichment; enrichment; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

   Sammanfattning : Cell functions are steered by complex interactions of gene products, like forming a temporary or stable complex, altering gene expression or catalyzing a reaction. Mapping these interactions is the key in understanding biological processes and therefore is the focus of numerous experiments and studies. LÄS MER
