  1. 1. Scalable Validation of Data Streams

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Cheng Xu; Uppsala universitet.; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Data Stream Management; Distributed Data Stream Processing; Data Stream Validation; Anomaly Detection; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Sammanfattning : In manufacturing industries, sensors are often installed on industrial equipment generating high volumes of data in real-time. For shortening the machine downtime and reducing maintenance costs, it is critical to analyze efficiently this kind of streams in order to detect abnormal behavior of equipment. LÄS MER

  2. 2. Techniques for the validation of Odin and ENVISAT satellite data

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ashley Jones; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; data assimilation; remote sensing; ozone; Odin; stratosphere; validation; limb sounding; MIPAS; balloon sonde; systematic;

    Sammanfattning : The depletion of ozone from the stratosphere and the impact of global warming have been identified as phenomena caused as a result of anthropogenic activity. Scientists are thus trying to find quicker and more reliable ways to analyse these environmental problems. LÄS MER

  3. 3. Validation and time series analysis of global stratospheric data sets

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; OSIRIS; MIPAS; remote sensing; data assimilation; Trend; stratosphere; ozone; linear regression; Odin; validation;

    Sammanfattning : The depletion of ozone from the stratosphere and the impact of global warming have been identified as phenomena caused as a result of anthropogenic activity. Scientists are thus trying to find quicker and more reliable ways to analyse these environmental problems. LÄS MER

  4. 4. On the Design and Validation of Fault Containment Regions in Distributed Communication Systems

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Håkan Sivencrona; RISE.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fault handling and membership agreement; Byzantine faults; asymmetric faults; fault injection; time-triggered protocol; fault containment regions; slightly-out-of-specification faults; validation;

    Sammanfattning : This thesis has a two fold focus where the first is an evaluation of a time-triggered communication protocol implementation, TTP-C1, which was stressed by use of heavy-ion fault injection. The gathered result showed a novel type of failures, earlier known only from theory, so-called slightly-out-of-specification faults, that manifested as Byzantine failures with resulting system inconsistence.

  5. 5. Definition and validation of requirements management measures

    Detta är en avhandling från Umeå : Datavetenskap

    Författare :Annabella Loconsole; Umeå universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Requirement; Measures; Volatility; Theoretical Validation; Empirical Validation; Prediction Model; Correlational Study; Subjective Estimation.; TECHNOLOGY Information technology Computer science Software engineering; TEKNIKVETENSKAP Informationsteknik Datavetenskap Programvaruteknik;

    Sammanfattning : The quality of software systems depends on early activities in the software development process, of which the management of requirements is one. When requirements are not managed well, a project can fail or become more costly than intended, and the quality of the software developed can decrease. LÄS MER
