2. 21. Carbody and Passengers in Rail Vehicle Dynamics

   Author : Pelle Carlbom; KTH; []
   Keywords : Rail-Vehicle Dynamics; Human-Body Dynamics; Ride Comfort; Structural Dynamics;

   Abstract : The carbody plays an important role in rail vehicle dynamics.This thesis aims atdeveloping validated modelling methods tostudy its dynamics, how it is excited on trackand how itinteracts with the passengers. The primary interest is ridecomfort,considering vibrations up to 20 Hz. READ MORE

4. 22. Gene Regulatory Networks: Dynamics and Stability

   Author : Carl Troein; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; systems; control; Datalogi; numerisk analys; system; kontroll; Computer science; numerical analysis; Fysik; biomathematics biometrics; Bioinformatik; medicinsk informatik; biomatematik; Physics; medical informatics; transcriptional regulation; gene regulatory networks; Bioinformatics; signaling pathway profiling; stem cell regulation; metabolic pathway; fitness; nested canalyzing rules; Kauffman networks; random Boolean networks; Fysicumarkivet:2007:Troein;

   Abstract : Life as we know it is based on cells that use proteins and RNA to carry out metabolism, self-replication, and other essential tasks. The genes that code for these molecules are encoded in DNA, and through the processes of transcription and translation the cell expresses its genes. READ MORE

5. 23. Analysis of manufacturing supply chains using system dynamics and multi-objective optimization

   Author : Tehseen Aslam; Amos H. C. Ng; Daniel Tesfamariam Semere; Högskolan i Skövde; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supply Chain Management; System Dynamics; Multi-Objective Optimization; Technology; Teknik;

   Abstract : Supply chains are in general complex networks composed of autonomous entities whereby multiple performance measures in different levels, which in most cases are in conflict with each other, have to be taken into account. Hence, due to the multiple performance measures, supply chain decision making is much more complex than treating it as a single objective optimization problem. READ MORE

6. 24. Algorithms for Molecular Dynamics Simulations

   Author : Fredrik Hedman; Aatto Laaksonen; Tom Darden; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; MD; first principles molecular dynamics; quantum mechanics; liquid water; parallel algorithm; data parallel; MPI; Coulombic interaction; Ewald summation; nonuniform fast Fourier transform; FFT; FFTW; NFFT; ENUF; Physical chemistry; Fysikalisk kemi;

   Abstract : Methods for performing large-scale parallel Molecular Dynamics(MD) simulations are investigated. A perspective on the field of parallel MD simulations is given. Hardware and software aspects are characterized and the interplay between the two is briefly discussed. READ MORE

7. 25. Geospatial Knowledge Discovery using Volunteered Geographic Information : a Complex System Perspective

   Author : Tao Jia; Bin Jiang; Yifang Ban; Itzhak Benenson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; knowledge discovery; urban systems; complex system; VGI; OSM; GPS tracking dataset; scaling; heavy-tailed distribution detection; urban sprawl; Zipf’s law; human activity mobility patterns; agent-based modeling; complex network.;

   Abstract : The continuous progression of urbanization has resulted in an increasing number of people living in cities or towns. In parallel, advancements in technologies, such as the Internet, telecommunications, and transportation, have allowed for better connectivity among people. READ MORE
