  1. 1. Design of Business Process Model Repositories : Requirements, Semantic Annotation Model and Relationship Meta-model

    Författare :Mturi Elias; Ilia Bider; Paul Johannesson; Marlon Dumas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; business process; business process model; business process repository; semantic annotation; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Business process management is fast becoming one of the most important approaches for designing contemporary organizations and information systems. A critical component of business process management is business process modelling. LÄS MER

  3. 2. Effect of Hyporheic Exchange on Conservative and Reactive Solute Transport in Streams : Model Assessments Based on Tracer Tests

    Författare :Karin Jonsson; Anders Wörman; Bernhard H. Schmid; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; conservative; hyporheic exchange; model; reactive; retention; solute; sorption kinetics; stream transport; temporal moments; tracer experiment; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

    Sammanfattning : Understanding of the processes affecting solute transport in flowing water is important for the possibility to predict the evolution with time of polluted stream systems. This thesis presents tracer experiment methodology and model developments for solute transport in streams, with special focus on retention processes and their effect on solute stream transport.

  4. 3. Investigation of perforated mufflers and plates

    Författare :Ying Guo; Mast Abom; Ragnar Glav; KTH; []
    Nyckelord :sound; perforated; micro-perforated; muffler; flow; hole; impedance; model; experiment;

    Sammanfattning :     Mufflers are used in for instance exhaust system of cars or trucks to reduce noise. Perforated pipes are one of the main components of modern mufflers. To study acoustic properties of mufflers with perforated pipe is one of the main targets of this thesis. LÄS MER

  5. 4. A model for simulation and generation of surrounding vehicles in driving simulators

    Författare :Johan Olstam; Jan Lundgren; Pontus Matstoms; Stéphane Espié; Linköpings universitet; []
    Nyckelord :Traffic; Simulation; Model; Traffic flow; Vehicle; Micro; Overtaking; Vehicle spacing; Deceleration; Acceleration; Mathematical model; Simulator; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

    Sammanfattning : Driving simulators are used to conduct experiments on for example driver behavior, road design, and vehicle characteristics. The results of the experiments often depend on the traffic conditions. One example is the evaluation of cellular phones and how they affect driving behavior. LÄS MER

  7. 5. The Aerodynamic Correlation of a Scale Model with a Full Size Car

    Författare :Lasse Malmkjaer Christoffersen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooling flow.; Correlation; Experiment; Reynolds number; Road Vehicle Aerodynamics; CFD; Scale model;

    Sammanfattning : Reducing the Worlds consumption of energy has become an important part of the current political and environmental debate. The reasons are obvious: World population is increasing, continued growth in living standards, finite availability of resources and finally green house gas emissions from energy production have to be brought down to stabilize temperatures.
