The importance of employees as knowledge workers acting in the correct roles is not a new phenomenon, but as work itself becomes less tangible, concerns with understanding, describing, and managing roles becomes an increasingly complex, challenging, and important subject. In the knowledge...

In this paper, an approach to geocode tweets published in Spanish is proposed. The tweets are related to traffic events within an urban context of the Mexico City. They are generated by a particular phenomenon for knowing the behavior of the involved geographic entities. In order to disambiguate...

This paper is a literature review to compare selected dimensions of manufacturing, services and R&D sectors supply chains. Each supply chain is seen as a system which proper input should be proceed to gain appropriate output. Therefore, to study the supply chains, inputs, outputs and the...

As population and human activities expand they exert heavy environmental pressure through the resource requirement, their production and consumption. Hence, it is important to understand the resource flows into the city, the transformations that take place and the resulting products and wastes....

Scheduling jobs in computational Grids is considered as NP-complete problem owing to the heterogeneity of shared resources. The resources belong to many distributed administrative domains that enforce various management policies. Therefore, the use of meta-heuristics are more appropriate option...

Cloud computing is the latest in distributed computing technology. The delivery mechanism between the service provider and users depends on Service Level Agreement (SLA). SLA contains Quality of Service (QoS), which has some constraints such as deadline to achieve user satisfaction. In this...

Limited resources and network dynamicity are challenging issues in Bluetooth networks. Therefore, scatternet formation improvement and efficient routing algorithms are required that can efficiently construct a short route between a source and destination. As of today, many protocols have been...

Grid computing has been used as a new paradigm for solving large and complex scientific problems using resource sharing mechanism through many distributed administrative domains. One of the most challenging issues in computational Grid is efficient scheduling of jobs, because of distributed...

We study the dynamics of the “Kolkata Paise Restaurant problem”. The problem is the following: In each period, N agents have to choose between N restaurants. Agents have a common ranking of the restaurants. Restaurants can only serve one customer. When more than one customer arrives at the...
