  1. 1. Spatial analysis and modeling of urban transportation networks

    Author : Jingyi Lin; Yifang Ban; Sten Henning Hansen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex networks; transportation systems; network growth; Evolving networks; centrality; urban systems; topology; space syntax; spatial networks; distance effects; gravity laws; planarity; street network patterns; US airline system; China’s aviation system; network efficiency; cellular structure; hierarchy; network representations; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : Transport systems in general, and urban transportation systems in particular, are the backbone of a country or a city, therefore play an intrinsic role in the socio-economic development. There have been numerous studies on real transportation systems from multiple fileds, including geography, urban planning, and engineering. READ MORE

  2. 2. Modelling and Simulation of Turbulent Gas-Solid Flows applied to Fluidization

    Author : Eric Peirano; Chalmers University of Technology; []
    Keywords : Eulerian models; fluidization; two-fluid model; two-phase flow; granular flow theory; turbulence; fluidized beds; gas-solid flows;

    Abstract : Modelling of gas-solid suspensions has been studied with emphasis on suitable closure laws. A study of characteristic time scales and energy dissipation mechanisms is made for the case of a simple shear flow. Applications of the modelling are presented in the form of simulation and validation of experiments in fluidized beds. READ MORE

  3. 3. Analysis of Dynamic Flight Loads

    Author : Natascha Jansson; Ulf Ringertz; David Eller; Peter Linde; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis deals with the determination of loads on an aircraft struc- ture during flight. The focus is on flight conditions where the loads are significantly time-dependent. Analysis of flight loads is primarily motivated to ensure that structural failure is avoided. READ MORE

  4. 4. Defining rape : emerging obligations for states under international law?

    Author : Maria Eriksson; Joakim Nergelius; Ola Engdahl; Helen Durham; Örebro universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Prohibition of rape; definition of rape; women s rights; armed conflict; state obligations; fragmentation; humanisation; LAW JURISPRUDENCE; RÄTTSVETENSKAP JURIDIK; Juridik; Law;

    Abstract : The prevalence of rape and its widespread impunity, whether committed during armed conflict or peacetime, has been firmly condemned by the UN and its prohibition has been consistently recognised in international law. This development, however, is a rather novel endeavour. READ MORE

  5. 5. Physics-based modelling and measurement of advanced manufacturing machinery’s positioning accuracy : Machine tools, industrial manipulators and their positioning accuracy

    Author : Nikolas Alexander Theissen; Andreas Archenti; Edward P. Morse; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Machine tools; Industrial robots; Accuracy; Measurement instruments; Production Engineering; Industriell produktion;

    Abstract : Advanced manufacturing machinery is a corner stone of essential industries of technologicallydeveloped societies. Their accuracy permits the production of complexproducts according to tight geometric dimensions and tolerances for high efficiency,interchangeability and sustainability. READ MORE
