1. 21. Towards Correct and Efficient Program Execution in Decentralized Networks: Programming Languages, Semantics, and Resource Management

   Författare :Karl Palmskog; Mads Dam; Rocco De Nicola; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; distributed objects; decentralization; implementation correctness; network protocols; object mobility; Computer Science; Datalogi;

   Sammanfattning : The Internet as of 2014 connects billions of devices, and is expected to connect tens of billions by 2020. To meet escalating requirements, networks must be scalable, easy to manage, and be able to efficiently execute programs and disseminate data. The prevailing use of centralized systems and control in, e.g. LÄS MER

3. 22. Pairing correlation in atomic nuclei under extreme conditions

   Författare :Sara A. Changizi; Chong Qi; Elvira Moya de Guerra Valgañón; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

   Sammanfattning : The pairing correlation has long been recognized as the dominant many-body correlation beyond the nuclear mean field. Pairing plays an essential role in many nuclear phenomena including the occurrence of a systematic odd-even staggering (OES) of the nuclear binding energy. LÄS MER

4. 23. Leaching and Transformation of Flame Retardants and Plasticizers under Simulated Landfill Conditions

   Författare :Maritha Hörsing; Bo H. Svensson; Susanne Jonsson; Anna Karlsson; Cynthia de Wit; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DEHP; BBP; tetrabromobisphenol A; TBBPA; TBBPA-DAE; TBBPA-DBPE; TBBPA-DHEE; Proban; Pyrovatex; Melamine; Environmental chemistry; Miljökemi;

   Sammanfattning : Many products used in our everyday life contain chemicals added to give them specific properties. Flame retardants (FRs) are added to prevent or retard fires in textiles, plastics etc., while plasticizers are supplied to make plastics more flexible. LÄS MER

5. 24. Finding, extracting and exploiting structure in text and hypertext

   Författare :Ola Ågren; Jürgen Börstler; Frank Drewes; Maarten de Rijke; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Automatic propagation; CHiC; Data mining; Discrete data; Extraction; Hierarchies; ProT; Rank distribution; S²ProT; Spatial linking; Web mining; Web searching; Computer science; Datalogi; business data processing; administrativ databehandling;

   Sammanfattning : Data mining is a fast-developing field of study, using computations to either predict or describe large amounts of data. The increase in data produced each year goes hand in hand with this, requiring algorithms that are more and more efficient in order to find interesting information within a given time. LÄS MER

7. 25. Language-based Approaches to Safe and Efficient Distributed Programming

   Författare :Xin Zhao; Philipp Haller; Roberto Guanciale; Wolfgang De Meuter; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Programming languages; Distributed systems; Type system; Replicated data types; Computer Science; Datalogi;

   Sammanfattning : Distributed systems address the increasing demand for fast access to resources and fault tolerance for data. Strong consistency ensures that all clients observe consistent data updates atomically on all servers in a distributed system, and it is widely used in systems such as relational databases. LÄS MER
