2. 1. Face Recognition : A Single View Based HMM Approach

   Author : Hung Son Le; Haibo Li; Josef Bigun; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; face recognition; pattern recognition; computer vision; HMM; Hidden Markov Models; contrast enhancement; pyramid fusion; image processing; Computer science; Datavetenskap;

   Abstract : This dissertation addresses the challenges of giving computers the ability of doing face recognition, i.e. discriminate between different faces. Face recognition systems are commonly trained with a database of face images, becoming “familiar” with the given faces. READ MORE

4. 2. Managing Natural Language Requirements in Large-Scale Software Development

   Author : Johan Natt och Dag; Institutioner vid LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; system; numerisk analys; Datalogi; control; requirements engineering; requirements management; linguistic engineering; natural language requirements; software engineering; software product development; Computer science; numerical analysis; systems; kontroll;

   Abstract : An increasing number of market- and technology-driven software development companies face the challenge of managing several thousands of requirements written in natural language. The large number of requirements causes bottlenecks in the requirements management process and calls for increased efficiency in requirements engineering. READ MORE

5. 3. Effects of Past and Current Land Use on Biodiversity: from a semi-natural grassland on Öland (Sweden) to a European perspective

   Author : Marie Vandewalle; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ecosystem services; bioindicators; land-use history; Biodiversity; semi-natural grasslands conservation; habitat fragmentation; functional diversity;

   Abstract : Concerns are increasing about the loss of biodiversity under land use change and how this will affect the ecosystem services provided by natural and semi-natural communities and consequently how this will threaten human well-being. The thesis examines the impact of present and past land use on different aspects of biodiversity; namely species diversity, traits and functional diversity and on ecosystem services. READ MORE

6. 4. Surface-Induced Modification of Supported Late Transition Metal Complexes

   Author : Olesia Snezhkova; Synkrotronljusfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene palladium complexes; X-ray photoelectron spectroscopy; electron charge transfer; iron phthalocyanine; catalysis; X-ray absorption spectroscopy;

   Abstract : The work presented in this thesis addresses the investigation of the electronic, magnetic, and structural properties of late transition metal complexes supported on various surfaces. The research is aimed at studying the interaction between the molecules and the support, together with the intermolecular interaction. This knowledge is essential e.g. READ MORE

7. 5. Global and continental perspectives on the sustainability of future agricultural water management

   Author : Luigi Piemontese; Fernando Jaramillo; Luigia Brandimarte; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; water; sustainable water management; agriculture; water harvesting; climate change; Sustainability Science; vetenskap om hållbar utveckling;

   Abstract : Ensuring water and food security in the Anthropocene requires an understanding of combined climate change patterns and land and water management options from local to global scale. In many regions, irrigation from river and groundwater sources is being used at unsustainable rates and climate change will further threaten those water sources. READ MORE
