  1. 1. Real-Time Search in Large Networks and Clouds

    Författare :Misbah Uddin; Rolf Stadler; Raouf Boutaba; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Networked systems, such as telecom networks and cloud infrastructures, hold and generate vast amounts of conguration and operational data, only a small portion of which is used today by management applications. The overall goal of this work is to make all this data available through a real-time search process named network search , where queries are invoked, without giving the location or the format of the data, similar to web search.

  3. 2. 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. 3. Color Emotions in Large Scale Content Based Image Indexing

    Författare :Martin Solli; Reiner Lenz; Björn Kruse; Stephen Westland; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Traditional content based image indexing aims at developing algorithms that can analyze and index images based on their visual content. A typical approach is to measure image attributes, like colors or textures, and save the result in image descriptors, which then can be used in recognition and retrieval applications. LÄS MER

  5. 4. The use of global data to uncover how humans shape flood and drought risk

    Författare :Sara Lindersson; Giuliano Di Baldassarre; Johanna Mård; Luigia Brandimarte; Brett Sanders; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; natural hazards; hydrological disasters; environmental geography; global geospatial data; international databases; disaster losses; disaster consequences; water management; dams and reservoirs; floodplains; hydrological drought; social vulnerability; economic inequality; Anthropocene; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Sammanfattning : The human consequences of flood and drought disasters are widespread and detrimental. Large-scale studies, drawing on global geodata products and international databases, can systematically examine how anthropogenic megatrends shape disaster risk and test the generalisability of findings from other scientific methodologies.

  7. 5. Discovery of Chemical Probes through Structure-based Virtual Screening of Vast Compound Databases

    Författare :Andreas Luttens; Jens Carlsson; Vsevolod Katritch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Bioactive molecules have traditionally been discovered through labor-intensive screening methods in which individual compounds are tested against specific protein targets or cells to identify those that produce the desired biological effect. However, these approaches have significant limitations. LÄS MER
