2. 1. Configuration Design of a High Performance and Responsive Manufacturing System : Modeling and Evaluation

   Author : Daniel Tesfamariam Semere; Bengt Lindberg; Bolmsjö Gunnar; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Configuration; Modeling; Evaluation; Manufacturing engineering; Produktionsteknik;

   Abstract : Configuring and reconfiguring a manufacturing system is presented as an issue with increasing importance due to higher frequency of system configuration or major reconfigurations to accommodate new set of requirements and/or the need to configure the system to make it usable across generations of products or product families. This research has focused in the modeling, evaluation and selection decisions which involves multiple, incommensurate and conflicting objectives. READ MORE

4. 2. Modeling Genome Evolution : Creation, Change and Destruction

   Author : Mats Pettersson; Otto Berg; Paul Sniegowski; Uppsala universitet; []
   Keywords : Molecular biology; Theotretical biology; Population genetics; Stochastic modeling; Genome evolution; Molekylärbiologi;

   Abstract : Historically, evolution has been studied either by looking at morphological traits in living organisms and the fossil record, or by using bioinformatics and comparative genomics. While highly useful for deducing evolutionary history, these approaches are not particularly well suited for studying the mechanisms of evolution. READ MORE

5. 3. Automation of Load Haul Dump machines : comparative performance analysis and maintenance modeling

   Author : Anna Gustafson; Sunniva Haugen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Abstract : The Load Haul Dump (LHD) machine and its operating environment create a complex system. Mine productivity depends on the operation of the LHDs and on the mining environment, including fragmentation, size of boulders, navigation techniques etc. Traditional navigation techniques require a lot of infrastructure to accommodate automatic operation.

6. 4. Environmental Modeling and Uncertainty

   Author : Muhammad Sarfraz Iqbal; Dik van de Meent; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; QSAR; multimedia fate modeling; uncertainty analysis; probability bounds analysis; fuzzy arithmetic; chemical safety assessment; REACH;

   Abstract : Environmental fate models are used to evaluate the fate and effects of chemicals for risk assessment. Fate models may be effective and low-cost substitutes for field measurements and are helpful to project future scenarios. READ MORE

7. 5. Towards a Scenario-based Spatial Dynamic Modeling for Predicting Urban Land Use Change : Planning Tools and Comparative Analysis

   Author : Zipan Cai; Vladimir Cvetkovic; Fredrik Gröndahl; Brian Deal; Stan Geertman; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; urbanization; planning support system; spatial dynamic model; urban land use change; spatial analysis; human-land interaction; socioeconomics; ecological systems; urban amenities; environmental impact assessment; what-if; decision-making; urbanisering; planeringsstödsystem; rumslig dynamisk modell; förändring av stadsmarkanvändning; rumslig analys; mänsklig-land interaktion; socioekonomi; ekologiska system; urbana bekvämligheter; miljökonsekvensbeskrivning; vad-om; beslutsfattande; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : As global urbanization progresses, cities worldwide are growing in size, which leads to many economic, environmental, and management challenges. Recent advancements in spatial data analysis and algorithmic geography have also led to the development of various urban model-based planning support systems (PSS) for urban planning. READ MORE
