1. 1. Using digitalisation for data-driven freight curbside management. A perspective from urban transport planning

   Författare :Juan Pablo Castrellon; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban transport planning; urban freight transport; digitalisation; curbside management; freight parking; last-mile delivery; loading zone; data analytics;

   Sammanfattning : Given trends in urbanisation, e-commerce, active mobility and modal shifts, streets have sprung up as scenes of conflict where competing demands for curbside space have increased. Because public space is limited, urban transport planners are called to solve public space conflicts by defining how much space is allocated to specific users as a means to achieve sustainable cities.

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

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

   Sammanfattning : 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. LÄS MER

4. 3. Sediment sources and transport pathways, Lithuanian coastal zone

   Författare :Milda Kairytè; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sediment; grain size; mineralogy; Lithuania; coastal zone; provenance; geology;

   Sammanfattning : This thesis presents an investigation of recent sediments of the Lithuanian coastal zone, SE Baltic Sea. The main focus is upon the detailed documentation of grain size and mineralogy and the development of analytical methods using these essential and most common sediment parameters. LÄS MER

5. 4. Modelling of Traffic Performance for Swedish Roads and Motorways

   Författare :Per Strömgren; Harilaos Koutsopoulos; Nagui Rouphail; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural highway; Intersection; Capacity; Critical gap; Flare; Micro simulation; Motorway; Ramp; Weaving; Merging; Queue; Delay; Over-saturated; Time-space; Roadwork zone; variable speed limit; harmonization; Transportvetenskap; Transport Science;

   Sammanfattning : This thesis consists of five scientific articles oriented towards capacity. Managing capacity constraints with associated delays is a big issue at new design as well as at trimming existing traffic facilities. LÄS MER

7. 5. Moisture and Chloride Transport in Concrete

   Författare :Filip Nilenius; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiscale modelling; mass transport; coupled diffusion; statistical volume element; interfacial transition zone.; computational homogenization; mesoscale;

   Sammanfattning : Material properties pertaining to the physical phenomena of mass transport in concrete are important for the durability of concrete structures, and they can ultimately be derived from material heterogeneities found at different subscales. On the mesoscale level, these heterogeneities are mainly characterized by the presence of embedded aggregates in the cement paste, together with cracks. LÄS MER
