This paper describes an extension which can be added to any production planning model based on time-indexed formulations with at most one setupor mode-change per period. It allows to add constraints involving accumulated quantities over several time-slices implementing the concept of contiguity into the model. This feature is relevant to any kind of process industry. It allows to model batch an...

We examine the search of partitioned inverted files with particular emphasis on issues that arise from different types of partitioning methods. Two types of index partitions are investigated: namely Termld and Docld. We describe the search operations implemented in order to support parallelism in probabilistic search. We also describe higher level features such as search topologies in parallel ...

WebVR, a multi-user online virtual reality engine, is introduced. The main contributions are mapping the geographical space and virtual space to the P2P overlay network space, and dividing the three spaces by quad-tree method. The geocoding is identified with Hash value, which is used to index the user list, terrain data, and the model object data. Sharing of data through improved Kademlia netw...

Model Description • Actors: An infinite population of individuals indexed by ei, one’s ability to earn a secular income, and zi, one’s ideal level of doctrinal strictness. – ei ∼ g(e|θ), where θ captures human development and g(e|θ) satisfies the monotone likelihood ratio property (MLRP). – zi ∼ h(z|ρ), where ρ captures society’s overall preference for doctrinal strictness and h(z|ρ) satisfies ...

A recent trend in routing research is the use of overlay routing to improve end-to-end QoS without changing the network-level architecture. The key of this technology is to find an alternative route that can avoid congested routes, using an overlay network. Developing costefficient overlay routing in terms of calculation cost and information distribution cost needed to find an alternative route...

In double patterning lithography (DPL), overlay error between two patterning steps at the same layer translates into CD variability. Since CD uniformity budget is very tight, overlay control becomes a tough challenge for DPL. In this paper, we electrically evaluate overlay error for BEOL DPL with the goal of studying relative effects of different overlay sources and interactions of overlay cont...

Remote sensing (RS) has been widely adopted as a tool to investigate several biotic and abiotic factors, directly indirectly, related biodiversity conservation. European grasslands are one of the most biodiverse habitats in Europe. Most these subject priority conservation measure, human-induced processes threaten them. The broad expansions few dominant species usually reported drivers loss. In ...

The protocol described in this paper builds and maintains an overlay topology on top of an ad hoc network. The overlay is intended to be used by a routing application. As flooding is a key component of many route discovery mechanisms in MANETs, we evaluate the delivery percentage, bandwidth consumption and time duration of flooding a message on the overlay. We also consider the overlay path str...

We consider the problem of collaborative search across a large number of digital libraries and query routing strategies in a peerto-peer (P2P) environment. Both digital libraries and users are equally viewed as peers and, thus, as part of the P2P network. Our system provides a versatile platform for a scalable search engine combining local index structures of autonomous peers with a global dire...
