The 3D complex building models are commonly of massive data, detailed appearance and sophisticated topology. The LOD modelling and real-time visualization of such models have hampered the wider applications of Virtual Geographic Environments. Aimed at the drawback of traditional simplification methods—difficult to locate the components, primitives that have to be decimated, this paper proposes ...

Pervasive computing environments aim at providing users with advanced services, dynamically composed our of networked services. In these open environments, availability of specific networked service instances cannot be guaranteed over time as users move and services leave and join the network accordingly. A major challenge in pervasive environments is thus to maintain services functionalities d...

Quality-of-service (QoS)-enabled publish/subscribe (pub/sub) middleware provides powerful support for scalable data dissemination. It is hard, however, to maintain key QoS properties (such as reliability and latency) in dynamic environments for distributed real-time and embedded (DRE) systems (such as disaster relief operations or power grids). Managing QoS manually is often not feasible in dyn...

The process of knowledge elaboration is considered from the perspective of cognitive load theory. This theory assumes that the available knowledge structures in long-term memory (LTM) are used to organize and guide cognitive processing in complex learning. Accordingly, the role of external instructional guidance in the process of knowledge elaboration could be described as providing a substitut...

A new market based approach for transmission expansion planning in deregulated environments is presented in this paper. In this approach, transmission-planning decisions are made based on the electric power market conditions. The main contribution of this research is 1) Introducing a new probabilistic tool for analyzing the electric market conditions, 2) Defining new criteria for ranking transm...

Transcriptional regulatory networks (TRNs) transduce environmental signals into coordinated output expression of the genome. Accordingly, they are central for the adaptation of bacteria to their living environments and in host-pathogen interactions. Few attempts have been made to describe a TRN for a human pathogen, because even in model organisms, such as Escherichia coli, the analysis is hind...
