  1. 6. Distributed File System Metadata and its Applications

    Författare :Mahmoud Ismail; Jim Dowling; Seif Haridi; Luis Veiga; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Distributed hierarchical file systems typically decouple the storage and serving of the file metadata from the file contents (file system blocks) to enable the file system to scale to store more data and support higher throughput. We designed HopsFS to take the scalability of the file system one step further by also decoupling the storage and serving of the file system metadata. LÄS MER

  3. 7. Scaling Distributed Hierarchical File Systems Using NewSQL Databases

    Författare :Salman Niazi; Jim Dowling; Seif Haridi; Seif Haridi; Rui Oliveira; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : For many years, researchers have investigated the use of database technology to manage file system metadata, with the goal of providing extensible typed metadata and support for fast, rich metadata search. However, earlier attempts failed mainly due to the reduced performance introduced by adding database operations to the file system’s critical path. LÄS MER

  4. 8. Capturing semi-automated decision making : the methodology of CASADEMA

    Författare :Maria Nilsson; Tom Ziemke; Joeri van Laere; Tarja Susi; Amy Loutfi; Ann Bisantz; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Decision making; distributed cognition; human-computer interaction; semi-automated processes; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Information technology; Informationsteknologi; Datalogi; Computer and Systems Science; Teknik;

    Sammanfattning : This thesis presents a new methodology named CASADEMA (CApturing Semi-Automated DEcision MAking) which captures the interaction between humans and the technology they use to support their decision-making within the domain of Information Fusion. We are particularly interested in characterising the interaction between human decision makers and artefacts in semi-automated fusion processes. LÄS MER

  5. 9. Functional EDSLs for Web Applications

    Författare :Anton Ekblad; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; functional programming; domain-specific programming languages; distributed systems; web applications; tierless programming languages;

    Sammanfattning : This thesis aims to make the development of complex web applications easier, faster and safer through the application of strongly typed functional programming techniques. Traditional web applications are commonly written in the de facto standard language of the web, JavaScript, which, being untyped, provides no guarantees regarding the data processed by programs, increasing the burden of testing and defensive programming.

  7. 10. Design, implementation and evaluation of a distributed mediator system for data integration

    Författare :Vanja Josifovski; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : An important factor of the strength of a modern enterprise is its capability to effectively store and process information. As a legacy of the mainframe computing trend in recent decades, large enterprises often have many isolated data repositories used only within portions of the organization. LÄS MER
