1. Opportunistic Networking : Mobility Modeling and Content Distribution
Sammanfattning : 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. LÄS MER
2. Modeling Organizational Dynamics : Distributions, Networks, Sequences and Mechanisms
Sammanfattning : 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. LÄS MER
3. Performance Analysis of Opportunistic Content Distribution via Data-Driven Mobility Modeling
Sammanfattning : 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.

4. Numerical modeling of dielectrophoresis
Sammanfattning : 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. LÄS MER
5. The effectiveness of a full-mobility architecture for wireless mobile computing and personal communications
Sammanfattning : 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. LÄS MER
