  1. 1. Reflections on Process-based Supply Chain Modelling and Analysis

    Author : Robert Lindroth; Lunds universitet.; Lund University.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process mapping; supply chain management; modelling; simulation.;

    Abstract : The interest in modelling, analysis and optimisation of supply chain structures has increased in the last decade. Among the reasons are globalisation, a general speed-up of the rate of change in the business environment, the trend towards more outsourcing of activities, and the rapid development in IT.

  2. 2. Ridged sea ice modelling in climate applications

    University dissertation from Department of Meteorology, Stockholm University

    Author : Sebastian Mårtensson; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic ocean; Baltic Sea; sea ice; ice dynamics; numerical modelling; climate; ice deformation; ice compression; physical and biogeochemical interactions; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : This work aims to increase our understanding of the nature of large scale features of sea ice from a dynamics point of view.Sea ice plays an important part in the exchange of heat and humidity between sea and air and thus is an important component of the climate system. READ MORE

  3. 3. 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 : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper 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

  4. 4. Changes of evapotranspiration and water cycle in China during the past decades

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ge Gao; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Potential evapotranspiration; Actual evapotranspiration; Spatial and temporal characteristic; Trend; Controlling factors; Water cycle; Thornthwaite water balance; China;

    Abstract : Evapotranspiration is the second largest quantity in the water cycle and an important indicator for climate changes. Accurate estimations and better understanding of evapotranspiration are required in hydrologic studies and water resources modelling under stationary and changing climate conditions. READ MORE

  5. 5. Resampling Evaluation of Signal Detection and Classification With Special Reference to Breast Cancer, Computer-Aided Detection and the Free-Response Approach

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Bornefalk Hermansson; Uppsala universitet.; [2007]
    Keywords : Statistics; breast cancer; trend modelling; FROC; confidence intervals; threshold independence; bootstrap; kernel density estimation; mammography; computer-aided detection; Statistik;

    Abstract : The first part of this thesis is concerned with trend modelling of breast cancer mortality rates. By using an age-period-cohort model, the relative contributions of period and cohort effects are evaluated once the unquestionable existence of the age effect is controlled for. READ MORE
