  1. 1. Disease surveillance systems

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Baki Cakici; KTH.; RISE.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS Health and medical services in society; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN Hälso- och sjukvård i samhället; MEDICINE Social medicine Public health medicine research areas Epidemiology; MEDICIN Socialmedicin Folkhälsomedicinska forskningsområden Epidemiologi; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Computer and systems science; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Data- och systemvetenskap; disease surveillance; syndromic surveillance; outbreak detection; health informatics; computer science;

    Sammanfattning : Recent advances in information and communication technologies have made the development and operation of complex disease surveillance systems technically feasible, and many systems have been proposed to interpret diverse data sources for health-related signals. Implementing these systems for daily use and efficiently interpreting their output, however, remains a technical challenge. LÄS MER

  2. 2. Univariate and Multivariate Surveillance of Outbreaks

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Linus Schiöler; Göteborgs universitet.; Gothenburg University.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; change-points; expected delay; exponential family; false alarms; generalised likelihood; inference principles; influenza; MEWMA; monitoring; multivariate; ordered regression; performance metrics; outbreak; predictive value; subjective judgment; spatial; statistical models; surveillance; tularemia;

    Sammanfattning : In many areas there is a need to monitor observations in order to detect changes in the underlying processes as quickly as possible. The theory of statistical surveillance provides the possibility of making optimal decisions about whether a change has occurred or not based on the data available at the time of the decision.

  3. 3. Tracking and Planning for Surveillance Applications

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Per Skoglar; Linköpings universitet.; Linköpings universitet.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; target tracking; sensor control; planning; surveillance; vision sensor;

    Sammanfattning : Vision and infrared sensors are very common in surveillance and security applications, and there are numerous examples where a critical infrastructure, e.g. a harbor, an airport, or a military camp, is monitored by video surveillance systems. LÄS MER

  4. 4. Conformal anomaly detection Detecting abnormal trajectories in surveillance applications

    Detta är en avhandling från Skövde : University of Skövde

    Författare :Rikard Laxhammar; Högskolan i Skövde.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anomaly detection; conformal prediction; trajectory analysis; video surveillance; maritime surveillance; Teknik; Technology;

    Sammanfattning : Human operators of modern surveillance systems are confronted with an increasing amount of trajectory data from moving objects, such as people, vehicles, vessels, and aircraft. A large majority of these trajectories reflect routine traffic and are uninteresting. LÄS MER

  5. 5. Characterization of RNA exosome in Insect Cells Role in mRNA Surveillance

    Detta är en avhandling från Stockholm : Department of Molecular Biology and Functional Genomics, Stockholm University

    Författare :Viktoria Hessle; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell nucleus; nuclear bodies; mRNA surveillance; cotranscriptional assembly; Rrp6; Rrp4; mRNP; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : The exosome, an evolutionarily conserved protein complex with exoribonucleolytic activity, is one of the key players in mRNA quality control. Little is known about the functions of the exosome in metazoans. We have studied the role of the exosome in nuclear mRNA surveillance using Chironomus tentans and Drosophila melanogaster as model systems. LÄS MER
