2. 1. Simulations of human movements through temporal discretization and optimization

   Author : Manindra Kaphle; Anders Eriksson; Kjartan Halvorsen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forward dynamics; Biomechanics; Temporal discretization; Optimization; Engineering mechanics; Teknisk mekanik;

   Abstract : Study of physical phenomena by means of mathematical models is common in various branches of engineering and science. In biomechanics, modelling often involves studying human motion by treating the body as a mechanical system made of interconnected rigid links. READ MORE

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

   Author : Karin Jonsson; Anders Wörman; Bernhard H. Schmid; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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.

5. 3. The Lagrangian Stochastic Advective-Reactive Approach to Modeling Solute Transport in Hydrological Systems

   Author : Archana Gupta; KTH; []
   Keywords : solute transport; groundwater transport; unsaturated zone; stream hydrology; stream networks; stochastic processes; mass transfer kinetics; preferential flow; temporal moments; catchment hydrology; Lagrangian transport model;

   Abstract : The Lagrangian stochastic advective-reactive modelingapproach has been used for analyzing transport of bothnonreactive and reactive solutes in different hydrologicalsystems (structured soil, groundwater, mining waste rockdeposits and surface waters including single stream and networkof streams) and at different spatio-temporal scales (rangingfrom laboratory column-scale to catchment-scale). Further, afirst step has been taken to extending the Lagrangianstochastic advective-reactive modeling methodology to integratethe soil-groundwater-stream transport through a catchment. READ MORE

6. 4. Effect of Uncertainty of Rock Properties on Radionuclide Transport by Groundwater : Implications for Performance Assessments of the Repository of Spent Nuclear Fuel in Heterogeneous Bedrock

   Author : Shulan Xu; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Radionuclide migration; heterogeneous rock property; stochastic process spectral analysis; temporal moments; auto-covariance functions; sorption kinetics; performance assessment; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

   Abstract : The overall objective of the current study is to develop a quantitative understanding of the effects of spatial variability in physical and geochemical properties of crystalline rock on the migration of radionuclides along a single fracture in bedrock. A stochastic model was developed to describe the transport of solutes in fractured rock. READ MORE

7. 5. Influential Moments in City Planning Meetings : A Study of Decision-Making Situations in a Jordanian Municipality

   Author : Marwa Al Khalidi; Institutionen för arkitektur och byggd miljö; []
   Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; decision-making; planning culture; city planning meetings; Jordan; destabilizations; heterogeneity; participant observation; controversy; actor-network theory; influential moments; narrative;

   Abstract : The shaping of a city and its future relates to official decisions made in city planning meetings, where daily planning matters and decision-making processes adapt to changing societal circumstances. The interest of this research lies in how planning is officially established, managed and practiced in the setting of a Jordanian city, and its local districts. READ MORE
