  1. 1. Data mining of geospatial data: combining visual and automatic methods

    University dissertation from Stockholm : KTH

    Author : Urška Demšar; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geographic information science; geoinformatics; geovisualisation; spatial data mining; visual data mining; usability evaluation; TECHNOLOGY Information technology Other information technology; TEKNIKVETENSKAP Informationsteknik Övrig informationsteknik;

    Abstract : Most of the largest databases currently available have a strong geospatial component and contain potentially useful information which might be of value. The discipline concerned with extracting this information and knowledge is data mining. Knowledge discovery is performed by applying automatic algorithms which recognise patterns in the data.

  2. 2. Biogeochemical data from SGU properties and applications

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kaj Lax; Luleå tekniska universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Abstract : Geochemical mapping is a technique that has been used all over the world for a multitude of purposes. The biogeochemical mapping programme conducted by the Geological Survey of Sweden (SGU) is mainly based on stream plant chemistry, which, opposed to mapping based on inorganic stream sediments or soils, is a method that is very uncommon.

  3. 3. Throughput and energy efficiency of lock-free data structures: Execution Models and Analyses

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Aras Atalar; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Modeling; Data Structures; Throughput; Concurrency; Energy Efficiency; Parallel Computing; Analysis; Performance; Lock-free;

    Abstract : Concurrent data structures are key program components to harness the available parallelism in multi-core processors. Lock-free algorithmic implementations of concurrent data structures offer high scalability and possess desirable properties such as immunity to deadlocks, convoying and priority inversion. READ MORE

  4. 4. Data Modeling for Outlier Detection

    University dissertation from Karlskrona : Blekinge Tekniska Högskola

    Author : Shahrooz Abghari; Blekinge Tekniska Högskola.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; data modeling; cluster analysis; stream data; outlier detection;

    Abstract : This thesis explores the data modeling for outlier detection techniques in three different application domains: maritime surveillance, district heating, and online media and sequence datasets. The proposed models are evaluated and validated under different experimental scenarios, taking into account specific characteristics and setups of the different domains. READ MORE

  5. 5. Scalable Validation of Data Streams

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Cheng Xu; Uppsala universitet.; Uppsala universitet.; [2016]
    Keywords : 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;

    Abstract : 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. READ MORE
