1. 1. Dynamics of Coinfection : Complexity and Implications

   Författare :Samia Ghersheen; Vladimir Kozlov; Uno Wennergren; Vladimir Tkachev; Åke Brännström; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Living beings are always on risk from multiple infectious agents in individual or in groups. Though multiple pathogens' interactions have widely been studied in epidemiology. Despite being well known, the co-existence of these pathogens and their coinfection remained a mystery to be uncovered. LÄS MER

3. 2. On some topics in operator theory : An unfinished story about mathematical control

   Författare :Eskil Rydhe; Harmonic Analysis and Applications; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carleson embeddings; complex analysis; control theory; functional models; Hankel operators; harmonic analysis; operator theory; Triebel–Lizorkin spaces; vector-valued analytic functions;

   Sammanfattning : This thesis considers differentiation of non-negative, fractional order, composed with Hardy spacetypeHankel operators. H2-boundedness is characterized in terms of a reproducing kernel thesis. LÄS MER

4. 3. Complexity in transportation and logistics systems : A conceptual approach to modelling and analysis

   Författare :Jonas Waidringer; Chalmers; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; management; measurement; logistics; modelling; complexity; transportation;

   Sammanfattning : The basis for the thesis is to assess the usefulness of describing and analysing transportation and logistics systems as being complex systems. The reason and assumption being that in the future more integrated and sophisticated systems and solutions will be demanded. LÄS MER

5. 4. Termination and Cost Analysis : Complexity and Precision Issues

   Författare :Abu Naser Masud; Samir Genaim; Germán Puebla; Technical University of Madrid; []
   Nyckelord :;

   Sammanfattning : The research in this thesis is related to static cost and termination analysis.Cost analysis aims at estimating the amount of resources that a given programconsumes during the execution, and termination analysis aims at proving thatthe execution of a given program will eventually terminate.

7. 5. Constructing Evolutionary Trees - Algorithms and Complexity

   Författare :Anna Östlin; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Maximum homeomorphic subtrees; Consensus trees; Experiment model; Evolutionary trees; Complexity; Computational biology; Algorithms; Data structures; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll; Biology; Biologi;

   Sammanfattning : In this thesis three general problems concerning construction of evolutionary trees are considered. Algorithms for the problems are presented and the complexity of the problems is investigated. The thesis consists of three corresponding parts. The first part is devoted to the problem of constructing evolutionary trees in the experiment model. LÄS MER
