2. 1. Operator and Machine Models for Dynamic Simulation of Construction Machinery

   Author : Reno Filla; Jan-Ove Palmberg; Jonas Larsson; Allan Ericsson; Tobias C. Larsson; Linköpings universitet; []
   Keywords : dynamic simulation; construction equipment; discrete simulation; continuous simulation; operator model; driver model; integrated product development; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : VIRTUAL PROTOTYPING has been generally adopted in product development in order to minimise the traditional reliance on testing of physical prototypes. It thus constitutes a major step towards solving the conflict of actual increasing development cost and time due to increasing customer demands on one side, and the need to decrease development cost and time due to increasing competition on the other.

   Abstract : Engine modeling and simulation have been necessary tools for efficient product development in the automotive industry for some time. The scope of this work is novel engine models, tools, and methods for powertrain research and development. READ MORE

5. 3. Dynamic Modelling and Simulation of Liquid Food Process Lines

   Author : Tomas Skoglund; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process lines; Dynamic model; Microbial deactivation; Data- och systemvetenskap; computer technology; Systems engineering; Fuzzy traceability; Traceability; Thermal engineering; termodynamik; Termisk teknik; applied thermodynamics; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; Heat exchanger; Dispersion; Fluid property transition; Liquid food; Dynamic simulation; Livsmedelsteknik;

   Abstract : In the present work a dynamic model library of components for process lines was developed. The analysis addressed characteristic aspects of liquid food process lines, and new models were developed for fluid transitions, dispersion, mixing zones and first-order chemical reactions in pipes and heat exchangers.

6. 4. Visualization and mesoscopic simulation in systems biology

   Author : Martin Falk; Thomas Ertl; Germany University of Stuttgart Visualization Research Center; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Scientific Visualization; GPGPU; Simulation; Systems Biology; Model Development; Signal Transduction;

   Abstract : Biological cells appear everywhere on earth. They might live on their own as unicellular organism, like bacteria, or might form complex organisms consisting of several thousands or millions of cells. Despite their small size of only a few micrometers, they are complex little miracles. READ MORE

7. 5. Simulation of dynamic instabilities during high rate deformation of ductile bars and plates

   Author : Kristina Nilsson; Mekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical simulation; non-linear; wave propagation; multiple necking; necking; buckling; fracture; Mechanical engineering; Maskinteknik; finite elements; cohesive elements; dynamic; J2-flow theory; J2-deformation theory; viscoplastic; background inertia;

   Abstract : In this thesis, some of the phenomena occurring in plates and cylindrical bars subjected to dynamic loading are investigated. Numerical simulations using a dynamic finite element code are performed for a number of different sized specimens with various initial surface imperfections. Typically imposed loading velocities are in the range 10m/s.. READ MORE
