2. 1. Ultimate and Residual Strength Assessment of Ship Structures

   Author : Artjoms Kuznecovs; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship structures; collision; corrosion; residual strength; ultimate strength; age-related degradation; nonlinear FEA; Smith method;

   Abstract : The prevention of ship structural failures and reduction of accident consequences contribute to increased safety at sea and reduced environmental impact. A need for reliable and efficient ship designs facilitates knowledge accumulation and the development of tools for the assessment of hull structural responses to acting loads. READ MORE

4. 2. Adaptive Finite Element Methods for the Reynolds Thin Film Model with Cavitation

   Author : Bertil Nilsson; Sweden Gothenburg Chalmers University of Technology Department of Applied Mechanics; []
   Keywords : tribology; Reynolds equation; cavitation; FEM; adaptivity; variational inequality; penalty formulation; error estimation; residual; duality;

   Abstract : The main purpose of this thesis is to use modern goal-oriented adaptive finite element techniques in order to improve the numerical simulation of tribology. Two novel adaptive finite element methods for the Reynolds thin film model including cavitation are presented and their different strategies are compared. READ MORE

6. 4. Evaluation of Dust Suppressants for Gravel Roads : Methods Development and Efficiency Studies

   Author : Karin Edvardsson; Björn Birgisson; Andrew Dawson; KTH; []
   Keywords : Gravel road; dust; particulate matter; PM10; horizontal dust diffusion; deteriorations; maintenance; dust control; dust suppressants; efficiency; application rate; leaching; residual concentration; seasonal variations; salt solution; solid salt; calcium chloride; magnesium chloride; lignosulphonate; polysaccharide sugar ; bitumen emulsion; rape oil; starch; surfactant; mesa; clay; fine material content;

   Abstract : Approximately 75 percent (300 000 km) of the total Swedish road network and 20 percent(20 000 km) of the national road network consists of gravel roads. One of the most significantproblems associated with gravel roads is traffic-generated dust emission, which contributes tothe deterioration of the road surface and acts as a major source of particulate matter releasedinto the atmosphere, thereby involving public economics, road safety, human health, andenvironmental quality.

7. 5. Evaluation of Dust Suppressants for Gravel Roads: Methods Development and Efficiency Studies

   Author : Karin Oscarsson; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gravel road; dust; particulate matter; PM10; horizontal dust diffusion; deteriorations; maintenance; dust control; dust suppressants; efficiency; application rate; leaching; residual concentration; seasonal variations; salt solution; solid salt; calcium chloride; magnesium chloride; lignosulphonate; polysaccharide sugar ; bitumen emulsion; rape oil; starch; surfactant; mesa; clay; fine material content.; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Abstract : Application of the proper dust suppressant to a gravel road ensures road safety and riding comfort as well as creating a cleaner and healthier environment for residents in buildings adjacent to the road. It also reduces the need and cost for vehicle repair, road maintenance activities, and aggregate supplementation. READ MORE
