1. 21. Convergence of Option Rewards

   Författare :Robin Lundgren; Dmitrii Silvestrov; Kimmo Eriksson; Anatoliy Malyarenko; Johan Tysk; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied mathematics; Tillämpad matematik; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Sammanfattning : This thesis consists of an introduction and five articles devoted to optimal stopping problems of American type options. In article A, we get general convergence results for the American option rewards for multivariate Markov price processes. These results are used to prove convergence of tree approximations presented in papers A, B, C and E. LÄS MER

3. 22. What Will We Learn? : A Mathematical Treatise of Cultural Evolution

   Författare :Pontus Strimling; Kimmo Eriksson; Robert Boyd; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cultural Evolution; Mathematical modeling; Applied mathematics; Tillämpad matematik; Matematik tillämpad matematik;

   Sammanfattning : In this thesis we apply mathematics and formal modeling to study culture from an evolutionary standpoint. Cultural evolution theory is based on the belief that we can increase our understanding of human behavior by studying how culture is created and spread. LÄS MER

4. 23. Fixed points, fractals, iterated function systems and generalized support vector machines

   Författare :Xiaomin Qi; Sergei Silvestrov; Anatoliy Malyarenko; Daniel Andren; Viktor Abramov; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; support vector machine; fixed points; iterated function system; variational inequality; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Sammanfattning : In this thesis, fixed point theory is used to construct a fractal type sets and to solve data classification problem. Fixed point method, which is a beautiful mixture of analysis, topology, and geometry has been revealed as a very powerful and important tool in the study of nonlinear phenomena. LÄS MER

5. 24. Optimization of Just-in-Time Sequencing Problems and Supply Chain Logistics

   Författare :Gyan Thapa; Sergei Silvestrov; Anatoliy Malyarenko; George Fodor; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Just-in-time; JIT sequencing; apportionment; product rate variation; output rate variation; algorithms; heuristics; supply chain; logistics; queueing; non-linear integer programming; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Sammanfattning : This dissertation presents a comprehensive and comparative progress in sequencing approaches of mixed-model just-in-time (JIT) sequencing problem together with discrete apportioment problem (DAP). The goal of JIT sequencing problem (JITSP) is to keep the rate of usage of parts as constant as possible along the assembly lines, and the goal of DAP is to divide a given integer number of delegates proportionally among the states or the parties according to their population or votes.

7. 25. Proportionalitetsbegreppet i den svenska gymnasiematematiken : en studie om läromedel och nationella prov

   Författare :V. L. Anna Lundberg; Christer Bergsten; Kirsti Hemmi; Astrid Pettersson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proportion; upper secondary school; textbooks; national course tests; curriculum; ATD; The anthropological theory of the didactics; missing value; numerical comparison; Qualitative prediction and comparison; Proportionalitets begreppet; proportionalitet; Matematik A; gymnasiet; läromedel; nationella prov; läroplaner; Lpf 94; ATD; reguladetri; saknat värde; missing value; numerical comparison; Qualitative prediction and comparison; Applied mathematics; Tillämpad matematik;

   Sammanfattning : Proportionalitet är ett centralt begrepp i skolmatematiken. Begreppet introduceras i de lägre stadierna och återkommer i så gott som samtliga kurser från årskurs 9 tillsista kursen på gymnasiet. Det övergripande syftet med denna studie är att undersöka hur det matematiska begreppet proportionalitet hanteras i den svenska gymnasieskolan. LÄS MER
