1. 1. A Differentiable Approach to Stochastic Differential Equations : the Smoluchowski Limit Revisited

   Författare :Haidar Al-Talibi; Astrid Hilbert; Yaozhong Hu; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; α-stable Lévy noise; Fractional Brownian motion; Girsanov theorem; Mean-field model; Nonlinear stochastic oscillator; Ornstein-Uhlenbeck process; Scaling limit; Second order Itô equation; Time change.; Matematik; Mathematics;

   Sammanfattning : In this thesis we generalize results by Smoluchowski [43], Chandrasekhar[6], Kramers, and Nelson [30]. Their aim is to construct Brownian motion as a limit of stochastic processes with differentiable sample paths by exploiting a scaling limit which is a particular type of averaging studied by Papanicolao [35].

3. 2. Cooperative Variable Speed Limit Systems : Modeling and Evaluation using Microscopic Traffic Simulation

   Författare :Ellen Grumert; Jan Lundgren; Andreas Tapani; Wilco Burghout; Statens väg- och transportforskningsinstitut; []
   Nyckelord :Variable speed limit; Traffic; Micro; Simulation; Data exchange; Telecommunication; Vehicle; Transport infrastructure; Intelligent transport system; In vehicle information; 23 Road: ITS och traffic; 23 Road: ITS och traffic; 25 Road: Traffic theory; 25 Road: Traffic theory;

   Sammanfattning : During the last decades the road traffic has increased tremendously leading to congestion, safety issues and increased environmental impacts. As a result, many countries are continuously trying to find improvements and new solutions to solve these issues. LÄS MER

4. 3. Understanding the mechanisms behind atom transfer radical polymerization : exploring the limit of control

   Författare :Helena Bergenudd; Mats Jonsson; Eva Malmström Jonsson; David M Haddleton; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymerization; controlled radical polymerization; atom transfer radical polymerization; kinetics; catalysis; electrochemistry; Polymer chemistry; Polymerkemi;

   Sammanfattning : Atom transfer radical polymerization (ATRP) is one of the most commonly employed techniques for controlled radical polymerization. ATRP has great potential for the development of new materials due to the ability to control molecular weight and polymer architecture. LÄS MER

5. 4. Patch loading resistance of plated girders : ultimate and serviceability limit state

   Författare :Jonas Gozzi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Sammanfattning : Patch loading or partial edge loading of steel girder webs is a load case where a concentrated force is introduced perpendicular to the flange of a girder. This usually induces a local failure of the girder web in the vicinity of the loaded flange. LÄS MER

7. 5. Prediction of the fatigue limit : accuracy of post-processing methods

   Författare :Sven Norberg; Mårten Olsson; Erland Johnson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other engineering mechanics; Övrig teknisk mekanik;

   Sammanfattning : Several fatigue criteria were evaluated with experimental fatigue test data. The fatigue tests contained many different geometries with different degrees of stress concentration. It was concluded that the differences between the criteria were neglectable when compared to the differences between the specimens. LÄS MER
