36. Cross-Layer Optimization of Voice over IP in Wireless Mesh Networks
Sammanfattning : Wireless Mesh Networks (WMNs) have emerged as a promising network technology, which combines the benefits of cellular networks and Wireless Local Area Networks (WLANs). In a WMN mesh routers wirelessly relay traffic on behalf of other mesh routers or clients and thereby provide coverage areas comparable to cellular networks, while having the low complexity and low costs of WLANs.

37. NML3 : a non-monotonic formalism with explicit defaults
Sammanfattning : The thesis is a study of a particular approach to defeasible reasoning based on the notion of an information state consisting of a set of partial interpretations constrained by an information ordering. The formalism proposed, called NML3, is a non-monotonic logic with explicit defaults and is characterized by the following features: (1) The use of the strong Kleene three-valued logic as a basis.

38. Security and trust mechanisms for groups in distributed services
Sammanfattning : Group communication is a fundamental paradigm in modem distributed services, with applications in domains such as content distribution, distributed games, and collaborative workspaces. Despite the increasing interest in group-based services and the latest developments in efficient and reliable multi cast, the secure management of groups remains a major challenge for group communication.

39. On Switchover Performance in Multihomed SCTP
Sammanfattning : The emergence of real-time applications, like Voice over IP and video conferencing, in IP networks implies a challenge to the underlying infrastructure. Several real-time applications have requirements on timeliness as well as on reliability and are accompanied by signaling applications to set up, tear down and control the media sessions. LÄS MER
40. Ett dynamiskt perspektiv på individuella skillnader av heuristisk kompetens, intelligens, mentala modeller, mål och konfidens i kontroll av mikrovärlden Moro
Sammanfattning : Theories predicting performance of human control of complex dynamic systems must assess how decision makers capture and utilise knowledge for achieving and maintaining control. Traditional problem solving theories and corresponding measures such as Ravens matrices have been applied to predict performance in complex dynamic systems. LÄS MER
