2. 1. Opportunistic Networking : Mobility Modeling and Content Distribution

   Author : Ljubica Pajevic; Gunnar Karlsson; Karin Anna Hummel; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; opportunistic networks; ad hoc networks; mobility modeling;

   Abstract : We have witnessed two main trends in recent years that have shaped the current state of communication networks. First, the Internet was designed with the initial idea to provide remote access to resources in the network; today it is overwhelmingly being used for content distribution. READ MORE

4. 2. Modeling Organizational Dynamics : Distributions, Networks, Sequences and Mechanisms

   Author : Hernan Mondani; Fredrik Liljeros; Rickard Sandell; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; organizational dynamics; social organizing; organizational change; modeling; organizational growth; process stability; labor flow network; employment trajectories; heavy-tailed distributions; complex network analysis; sequence analysis; agent-based modeling; sociophysics; Sociology; sociologi;

   Abstract : The study of how social organizations work, change and develop is central to sociology and to our understanding of the social world and its transformations. At the same time, the underlying principles of organizational dynamics are extremely difficult to investigate. READ MORE

5. 3. Performance Analysis of Opportunistic Content Distribution via Data-Driven Mobility Modeling

   Author : Ljubica Pajevic; Viktória Fodor; Thrasyvoulos Spyropoulos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Opportunistic communication; mobility; content distribution; network performance modeling; trace-collection analysis; stochastic models.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : An opportunistic network is formed by co-located mobile users in order to exchange data via direct wireless links when their devices are within transmission range, without relying on the use of fixed network infrastructure. In this thesis we investigate the capabilities of opportunistic networks and cover two main areas: data-driven modeling of user mobility and analytic performance evaluation of location-aware opportunistic content distribution.

6. 4. Numerical modeling of dielectrophoresis

   Author : Yuan Lin; Gustav Amberg; Olof Runborg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dielectrophoresis; orientation of rotation; fluid particle dynamics; microparticle; molecular dynamics; hydrodynamics; particle-particle interaction; superimposed; mobility; Fluid mechanics; Strömningsmekanik;

   Abstract : We investigate the dielectrophoretic separation of microparticles. Two different models are formulated in two characteristic time scales. The first model mainly accounts for the orientation behavior and rotational motion of non-spheric microparticles. The concept of effective charge is suggested to calculate the finite size non-spheric particles. READ MORE

7. 5. The effectiveness of a full-mobility architecture for wireless mobile computing and personal communications

   Author : George Yuejin Liu; Gerald Maguire; Randy Katz; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobile Computing; Mobile-API; Mobile Agent; Mobile Floating Agent; Intelligent Agent; Full-Mobility; Mobility Architecture; Mobility Awareness; Location Awareness; Location Prediction; Mobile Personal Communications.;

   Abstract : The emergence of wireless mobile computing, especially the mobility of computers, introduces challenging new problems that were encountered in neither the design and implementation of conventional mobile networks or in fixed computer networks. A critical and challenging problem, for mobile computing and personal communications, is how to fully cope with the special characteristics of the mobile wireless environment, i. READ MORE
