1. Path Choice Estimation in Urban Rails : Asimulation based optimisation for frequency-based assignment model
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Transit system have a large importance in modern urban cities, with urban rail often acting as the central system with it efficient travel time and great capacity. As cities grow in population, so to does the usage of urban rail resulting in increased crowding on the platform and in the trains. LÄS MER
2. Stochastic Lateral Transshipment within the Fast Fashion Industry
Master-uppsats, KTH/Matematik (Inst.)Sammanfattning : In an industry with highly variable demand and a fickle customer demanding a fast changing supply, quickly responding to the customer becomes crucial for the fast fashion retailer. Using lateral transshipment, one is able to reorganize supply within an echelon of the supply chain to quickly respond to the forecasted demand by looking at shorter more accurate forecasts and act accordingly.

3. Multiscale numerical approximation of morphology formation in ternary mixtures with evaporation : Discrete and continuum models for high-performance computing
Master-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)Sammanfattning : We propose three models to study morphology formations in interacting ternary mixtures with the evaporation of one component. Our models involve three distinct length scales: microscopic, mesoscopic, and respectively, macroscopic. LÄS MER
4. Energieffektivisering av falsvärmesystem i vattenkraftverk
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : För att undvika att dammluckor vid vattenkraftverk fryser fast under vintern är det vanligt med värme kring luckorna där uppvärmningen sköts av ett falsvärmesystem. Falsvärmesystemen saknar energimätning men har med sin relativt höga installerade effekt antagits ha en betydande inverkan på den interna energianvändningen. LÄS MER
5. Reissner Mixed Variational Theorem for Ritz Sublaminate Generalized Unified Formulation
Master-uppsats, KTH/LättkonstruktionerSammanfattning : This thesis is about the development of a new numerical method for the analysis of composite shells. The present work is based on Reissner Mixed Variational Theorem (RMVT), the Sublaminate Generalized Unified Formulation (S-GUF), and the Ritz approximation. LÄS MER
