This paper mainly investigates the location problem of multi-product logistics distribution centers in uncertain environment. Based on the assumption that the customers’ demands and the transportation times are uncertain variables, an uncertain programming model is constructed. On the precondition of satisfying the capacity constraint and time window constraint, the objective of the model is to...

Myelin regeneration is indispensably important for patients suffering from several central nervous system (CNS) disorders such as multiple sclerosis (MS) and spinal cord injury (SCI), because it is not only essential for restoring neurophysiology, but also protects denuded axons for secondary degeneration. Understanding the cellular and molecular mechanisms underlying remyelination is critical ...

This paper develops a two-stage stochastic program and solution procedure to optimize the selection of seismic retrofit strategies to increase the resilience of electric power systems to earthquake hazards. The model explicitly considers the range of earthquake events that are possible and, for each, an approximation to the distribution of damage that is experienced. This is important because e...

We introduce the opinion-based entity profiling task, understood as the automatic grouping of equivalent or very similar online opinions (both positive and negative) about an entity. This is a highly practical problem that arises in the context of online reputation management, but it has not been directly addressed by any Natural Language Processing evaluation campaign or specific benchmarking ...

In today’s economy, the role and value of knowledge as the last competitive advantage has been suggested and the Knowledge Management (KM) concept has emerged and received great attention. A big part in KM is about managing the way knowledge flows in and between organizations i.e., managing Knowledge Sharing (KS). While technology admittedly facilitates KS, the success of KM efforts still depen...

“Bushisms” (“We shouldn’t fear a world that is more interacted”) and the complex response to them from both right and left. Perhaps it is the hype over Instant Messaging lingo cropping up in formal writing and the debate among teachers over how to respond (Farmer 48). Perhaps it is the long series of attempts to loosen the grip of “standard” English on the public imagination, from the 1974 spec...

In this paper I shall present a treatment of lexical and grammatical tone and vowel length in Hausa, as implemented in an emerging bidirectional HPSG of the language based on the Lingo Grammar Matrix (Bender et al., 2002). I shall argue in particular that a systematic treatment of suprasegmental phonology is indispensible in an implemented grammar of the language, both for theoretical and pract...
