1. 36. Biomass gasification in fluidized bed gasifiers : Modeling and simulation

   Författare :Guilnaz Mirmoshtaghi; Erik Dahlquist; Jan Brandin; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Using woody biomass as a resource for production of biofuel, heat and power through gasification has been studied for years. In order to reduce the cost of operating and to design the full-scale gasification plant developing a general model to be applicable for different ranges of input data with acceptable level of accuracy, is needed.

3. 37. Compression moulding of SMC : experiments and simulation

   Författare :Jimmy Olsson; Daniel Ståhlberg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : Due to excellent properties and relatively low material and manufacturing costs, the use of fibre reinforced polymer composites have increased during the last decades. One method that is suitable for large scale productions of e.g. lightweight vehicle components is compression moulding of sheet moulding compound (SMC). LÄS MER

4. 38. Simulation based design : structural optimization at early design stages

   Författare :Marcus Redhe; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The aim of this thesis is to evaluate and develop different modelling tools which can be used in the vehicle crashworthiness design process. These tools will improve the understanding of the vehicle behaviour and thus improve the crashworthiness of the vehicle. LÄS MER

5. 39. A Traffic Simulation Modeling Framework for Rural Highways

   Författare :Andreas Tapani; Jan Lundgren; Karl-Lennart Bång; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic; Micro; Simulation; Model; Overtaking; Speed; Headway; Rural road; Electronic driving aid; Mathematical model; Road: Traffic theory; Road: Traffic theory; Other technology;

   Sammanfattning : Models based on micro-simulation of traffic flows have proven to be useful tools in the study of various traffic systems. Today, there is a wealth of traffic microsimulation models developed for freeway and urban street networks. The road mileage is however in many countries dominated by rural highways. LÄS MER

7. 40. Integrating Discrete Event Simulation into the Engineering Process Strategic Solutions for Increased Efficiency in Industrial System Development

   Författare :Pär Klingstam; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete event simulation; manufacturing system development; simulation methodology; simulation strategy; engineering integration;

   Sammanfattning : Efficient development processes are the key to being competitive, signified by short development lead times, low development costs, and high quality in all development activities. Previous research in academia as well as in industry suggested two important facilitators for obtaining such processes, namely structured development and modeling and simulation. LÄS MER
