  1. 1. Investigation and forecasting drift component of a gas sensor

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Farhana Chowdhury Tondra; [2021]
    Nyckelord :Time series analysis; Forecasting; ARIMA; LSTM; Sensor; SiC-FET; ADF test; Stochastic Trend; Deterministic Trend; Sensor Drift;

    Sammanfattning : Chemical sensor based systems that are used for detection, identification, or quantification of various gases are very complex in nature. Sensor response data collected as a multivariate time series signals encounters gradual change of the sensor characteristics(known as sensor drift) due to several reasons. LÄS MER

  3. 2. Continuous Validation of Multi-Cloud Systems by Automated Test Scripting

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Josefine Sandström; [2019]
    Nyckelord :Continuous validation; Multi-cloud; Technology and Engineering;

    Sammanfattning : Scalability, pay-as-you-go, and flexibility are some factors why more and more organizations are utilizing a cloud environment for their IT systems. Specifically, the trend is towards multi-cloud, where different cloud providers manage different applications and services. LÄS MER

  4. 3. On the use of integer and fractional flexible Fourier form Dickey-Fuller unit root tests

    Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Marcus Nordström; [2018]
    Nyckelord :Fractional frequency flexible Fourier form; Unit root test; Structural break; Smooth break; Nonlinear trend; Business and Economics;

    Sammanfattning : In this paper we propose the use of a new set of conservative critical values for the flexible Fourier form Dickey-Fuller unit root test when the Fourier frequency is estimated. We consider both the integer frequency and the fractional frequency version of the test and investigate their size and power properties. LÄS MER

  5. 4. Deterministic and Flexible Parallel Latent Feature Models Learning Framework for Probabilistic Knowledge Graph

    Master-uppsats, Mittuniversitetet/Avdelningen för informationssystem och -teknologi

    Författare :Xiao Guan; [2018]
    Nyckelord :Text classification; Recurrent neural network; Convolutional neural network;

    Sammanfattning : Knowledge Graph is a rising topic in the field of Artificial Intelligence. As the current trend of knowledge representation, Knowledge graph research is utilizing the large knowledge base freely available on the internet. Knowledge graph also allows inspection, analysis, the reasoning of all knowledge in reality. LÄS MER

  7. 5. The apparent population crash in heath-hares Lepus timidus sylvaticus of southern Sweden : do complex ecological processes leave detectable fingerprints in long-term hunting bag records?

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Alexander Winiger; [2014]
    Nyckelord :Lepus spp; Hunting bag time series; hyperpredation; competitive exclusion; Fennoscandia;

    Sammanfattning : Scientific and circumstantial evidence of recent decades indicate decreasing population trends in the native mountain hares Lepus timidus of Fennoscandia (Finland, Sweden, Norway). It has been suggested that climate warming, habitat degradation, pathogens, predation and interspecific competition are potential candidates to drive this supposed decline. LÄS MER
