Two integer-programming models are presented which optimize barge groupings into cost efficient configurations for transit. First a grouping IP is used to cluster barges with similar characteristics such as origin port, destination port, and pickup time so as to minimize dwell and handling cost. Next an assignment IP is used to assign groups to tow boats to minimize travel costs.

Collaborative environments present an happy hunting ground for worms due to inherent trust present amongst the peers. We present a novel control-theoretic approach to respond to zero-day worms in a signature independent fashion in a collaborative environment. A federation of collaborating peers share information about anomalies to estimate the presence of a worm and each one of them independent...

Base station cooperation in the downlink of cellular systems has been recently suggested as a promising concept towards a better exploitation of the communication system’s physical resources. It may offer a high gain in capacity through interference mitigation. This however, comes at a cost of high information exchange between cooperating entities and a high computational burden. Clustering of ...

Hurricane forecasts are intended to convey information that is useful in helping individuals and organizations make decisions. For example, decisions include whether a mandatory evacuation should be issued, where emergency evacuation shelters should be located, and what are the appropriate quantities of emergency supplies that should be stockpiled at various locations. This paper incorporates o...

The smartphone revolution together with cost-efficient wireless access technologies has lately changed the landscape for smart home environments to a large extent. Moreover, large flat screens, new capturing devices, and large digital media libraries have also changed the way smart home environments are used. We present and evaluate an architecture for multimedia sharing in such environments. E...

Manufacturing innovations are technologies and activities that improve and change the level of capacity, performance and quality in manufacturing permanently or over time. This policy brief explores the role of manufacturing innovations in different Nordic contexts, their link with production relocation decisions and performance implications. Manufacturing innovations are analyzed in terms of f...

This paper is concerned with long-run average cost minimization of a stochastic inventory problem with Markovian demand, fixed ordering cost, convex surplus cost, and lost sales. The states of the Markov chain represent different possible states of the environment. Using a vanishing discount approach, a dynamic programming equation and the corresponding verification theorem are established. Fin...

This review paper presents the state of the art on the problems, approaches and analytical models for assembly and transfer line design and balancing that addresses explicitly cost and profit oriented objectives. The discussions aim to facilitate identifying open problems and research areas that have wide practical applications and that necessitate further investigations. Moreover, they might s...

On the one side, network simulation frameworks are important tools for research and development activities to evaluate novel approaches in a timeand cost-efficient way. On the other side, Java as a highly platform-independent programming language is ideally suited for rapid prototyping in heterogeneous scenarios. Consequently, Java simulation frameworks could be used to firstly perform function...

Enterprises integration has recently gained great attentions, as never before. The paper deals with an essential activity enabling seamless enterprises integration, that is, a similarity-based schema matching. To this end, we present a supervised approach to measure semantic similarity between XML schema documents, and, more importantly, address a novel approach to augment reliably labeled trai...
