  2. 1. A generic construction process modelling method

    University dissertation from Institutionen för fastigheter och byggande

    Author : Vesa Karhu; KTH.; [2001]
    Keywords : process; modelling; generic; method; database; view;

    Abstract : A variety of modelling methods has been used to modelconstruction processes and projects, either during normalproject planning or for process re-engineering efforts orresearch. One common method, which is widely used byconstruction industry practitioners, is scheduling. READ MORE

  4. 2. Ontology as Conceptual Schema when Modelling Historical Maps for Database Storage

    University dissertation from Linköping University

    Author : Gustav Svedjemo; Linköpings universitet.; Linköpings universitet.; Högskolan på Gotland.; Högskolan på Gotland.; [2007]
    Keywords : ontology; historical maps; database modelling; GIS; Geographical Information Systems; archaeology; history; ontologi; historiska kartor; databasmodellering; GIS; geografiska informationssystem; arkeologi; historia;

    Abstract : Sweden has an enormous treasure in its vast number of large-scale historical maps from a period of 400 years made for different purposes, that we call map series. The maps are also very time and regional dependent with respect to their concepts. A large scanning project by Lantmäteriverket will make most of these maps available as raster images. READ MORE

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

    University dissertation from Department of Water Resources Engineering, LTH

    Author : Aman Mohammad Kalteh; Lunds universitet.; Lund University.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geographical and geological engineering; Hydrogeology; 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. Thermodynamic modelling and assessment of some alumino-silicate systems

    University dissertation from Stockholm : KTH

    Author : Huahai Mao; KTH.; [2005]
    Keywords : TEKNIKVETENSKAP; TECHNOLOGY; thermodynamic modelling; thermodynamic assessment; alumino-silicate system; slag; oxide system; CALPHAD; phase diagram; phase equilibrium; Thermo-Calc; compound energy formalism; ionic two sub-lattice liquid model; AlO2-1 species; Al2O3; CaO; MgO; SiO2; Y2O3; Materialvetenskap;

    Abstract : Alumino-silicate systems are of great interest for materials scientists and geochemists. Thermodynamic knowledge of these systems is useful in steel and ceramic industries, and for understanding geochemical processes. A popular and efficient approach used to obtain a self-consistent thermodynamic dataset is called CALPHAD. READ MORE

  7. 5. Terrain Modelling with GIS for Tectonic Geomorphology : Numerical Methods and Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gyözö Jordan; Uppsala universitet.; [2004]
    Keywords : TEKNIKVETENSKAP; TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik;

    Abstract : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. READ MORE
