  2. 1. Preprocessing perceptrons

    Author : Lena Kallin Westin; Patrik Eklund; Lothar Gierl; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Preprocessing perceptron; Production line; Neural networks; Backpropagation; Fuzzy logic; ROC and QROC curves; Multivariate decision limits; Datalogi; Computer science; Datalogi; business data processing; administrativ databehandling;

    Abstract : Reliable results are crucial when working with medical decision support systems. A decision support system should be reliable but also be interpretable, i.e. able to show how it has inferred its conclusions. READ MORE

  4. 2. Discrete Methods used in Graph Theory and Linear Programming

    Author : Olof Barr; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Perceptron Algorithm; Graph Theory; Linear Programming; Matematik;

    Abstract : The content of the thesis is divided into two parts; graph theory and linear programming. The main results in the first part concerns extremal graph theory. Here we want to determine the number of edges in a graph needed to ensure the existence of certain local structures. READ MORE

  5. 3. Rainfall-Runoff Modelling Using Artificial Neural Networks (ANNs)

    Author : Aman Mohammad Kalteh; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Self-organizing map; Feed-forward multilayer perceptron; Forecasting; Hydrological modelling; Missing values; Rainfall-runoff modelling; Estimation; Artificial neural networks;

    Abstract : Over the last decades or so, artificial neural networks (ANNs) have become one of the most promising tools for modelling hydrological processes such as rainfall-runoff processes. In most studies, ANNs have been demonstrated to show superior result compared to the traditional modelling approaches. READ MORE

  6. 4. Indicators of mastitis and milk quality in dairy cows : data, modeling, and prediction in automatic milking systems

    Author : Dorota Anglart; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Methods for generating predictions of important and generally accepted indicators of udder inflammation and poor milk quality, such as somatic cell count (SCC) or changes in milk homogeneity, are few. The aim of this thesis was to investigate methods to identify indicators of mastitis and poor milk quality in dairy cows using data generated by automatic milking systems (AMS). READ MORE

  7. 5. Improving the performance of the blast furnace ironmaking process

    Author : Guangqing Zuo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : In order to assist the operators' control activities and to further improve the performance of the blast furnace, efforts have been made to develop models for control of blast furnace operation and improvements of burden quality. The main objectives of the work were to design models for diagnosing and forecasting irregular furnace statuses and for predicting the silicon content of the hot metal, and to study the influence of the fluxes on the melting properties of fluxed pellets.
