Supply chain management (SCM) has rapidly emerged as the central field of competition in many industries and has captivated the top executives of companies in the recent past. Electronic commerce (EC) technologies have the potential to revolutionize how firms coordinate and manage their supply chain activities. This paper focuses on the emerging paradigm of Internetenabled supply chain manageme...

The entorhinal cortex (EC) serves as a gateway to the hippocampus and plays a pivotal role in memory processing in the brain. Superficial layers of the EC convey the cortical input projections to the hippocampus, whereas deep layers of the EC relay hippocampal output projections back to the superficial layers of the EC or to other cortical regions. Whereas the EC expresses long-term potentiatio...

A brief review of the theory contributions presented in the EC-18 Workshop is given. The covered spectrum of topics is quite broad including the electron cyclotron wave propagation physics as well the results of numerical modelling of transport and current drive.

I survey the parameter space of NAHE-based free fermionic heterotic string models. First, I discuss flat directions of the low energy effective field theories and show that D-flat directions need not be isomorphic to gauge invariant superpotential terms. Next, I review recent studies of three generation SU(3)C × SU(2)L × U(1)Y , SU(3)C ×SU(2)L ×SU(2)R ×U(1)B−L, SU(4)C × SU(2)L ×U(1)Y ′ , and fl...

Globalization of production and the increasing competitive pace spurs greater business use of online networks. As economic globalization extends its reach over cities and regions, the positions of regional economies within the emerging global paradigm is changing. Only those regions and cities that can mobilize assets for local advantage are expected to succeed. This research examines the role ...

A fitness landscape presents the relationship between individual and its reproductive success in evolutionary computation (EC). However, discrete and approximate landscape in an original search space may not support enough and accurate information for EC search, especially in interactive EC (IEC). The fitness landscape of human subjective evaluation in IEC is very difficult and impossible to mo...

We investigate experimentally the performance of de ec tion networks for jitter sensitive tra c It is a com mon belief that pure de ection networks are not suit able for isochronous applications and networks based on a connection oriented paradigm are the only solution in such cases We argue to the contrary and present simulation results supporting our claims

In this paper we introduce an Evolutionary Computation (EC) software system which addresses many of the current needs of the EC research and development community. Java Evolving Objects library (JEO) provides a exible and powerful framework for developing EC experiments. The package makes extensive use of the objectoriented paradigm, so that new experiments can be easily implemented by reusing ...

The event calculus was proposed as a formalism for reasoning about time and events. Through the years, however, a much simpler variant (SEC) of the original calculus (EC) has proved more useful in practice. We argue that EC has the advantage of being more general than SEC, but the disadvantage of being too complex and in some cases erroneous. SEC has the advantage of simplicity, but the disadva...

The standard inter-domain routing protocol in the Internet today is Border Gateway Protocol (BGP) version 4. Studies conducted in recent years reveal that BGP suffers from several inherent problems, the most important of which are slow convergence and instability. BGP is also known to suffer from lack of Quality of Service (QoS) and inter-AS multicast support. In this work we present a new para...
