  1. 1. Dynamic Modelling of Transit Operations and Passenger Decisions

    Författare :Oded Cats; Haris Koutsopoulos; Tomer Toledo; Wilson Nigel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public Transport; Transit Operations; Simulation Model; Traffic Simulation; Route Choice; Dynamic Model; Assignment Model; Control; SRA - Transport; SRA - Transport;

    Sammanfattning : Efficient and reliable public transport systems are fundamental in promoting green growth developments in metropolitan areas. A large range of Advanced Public Transport Systems (APTS) facilitates the design of real-time operations and demand management. LÄS MER

  2. 2. Advanced TCAD Simulations and Characterization of Semiconductor Devices

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Tony Ewert; Jörgen Olsson; Marcel Pelgrom; [2006]
    Nyckelord :Electronics; MOSFET; RDF; random dopant fluctuation; asymmetric; parametric mismatch; TCAD; compact modeling; fluctuation model; Elektronik;

    Sammanfattning : Today, micro- and nano-electronic devices are becoming more complex and advanced as the dimensions are shrinking. It is therefore a very challenging task to develop new device technologies with performance that can be predicted. LÄS MER

  3. 3. Generic Properties of Polymer Solutions

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Takashi Uematsu; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photon correlation spectroscopy; collective diffusion; atomic force microscopy; relaxation; agarose gel electrophoresis; DNA; Zimm dynamics; pulsed-field gradient NMR; superdiffusion; polymer solution; blob model; gel;

    Sammanfattning : Polymer solutions are abundantly present in our daily life, for example in paints, jellies, contact lenses and even in the living cells. Despite their ubiquity, we still have a poor understanding of the physical properties of solutions due to the extremely large number of internal degrees of freedom. LÄS MER

  4. 4. Mini-Jet Production in Proton-Antiproton Interactions and Particle Production in Heavy-Ion Collisions

    Detta är en avhandling från Experimental High-Energy Physics

    Författare :Haiqiao Wang; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proton antiproton interaction; Quark-gluon plasma; dynamical fluctuation; intermittency; limiting fragmentation; intranuclear cascading; target fragmentation; heavy-ion collision; image processing; mini-jet; Nuclear physics; Kärnfysik; Fysicumarkivet A:1997:Wang;

    Sammanfattning : The thesis is based on the data analysis and detector development of the EMU01/CERN, E863/BNL and UA1/CERN experiments. Particle fluctuations are studied with the scaled factorial moments in the fragmentation region of oxygen-induced emulsion interactions from 3.7 to 200 A GeV. LÄS MER

  5. 5. Numerical optimization of hull/propeller/rudder configurations

    Detta är en avhandling från Experimental High-Energy Physics

    Författare :Kaijia Han; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel cost savings; optimization; pressure fluctuation; self-propulsion; RANS; verification and validation; cavitation; open water; lifting surface; hull-propeller-rudder; effective wake; efficiency; aspect ratio; lifting line; interaction;

    Sammanfattning : The new framework of the global economy has stimulated and expanded the shipbuilding and shipping industry, especially in Asia in the twenty-first century. This induces urgent and high requirements on designing and building both conventional and new types of ships with high performance, such as high speed, manoeuvrability, seaworthiness and so on.
