Globalization, the knowledge society, and the Network State: Poulantzas at the millennium

GLOBAL NETWORKS, Issue 1 2001
Martin Carnoy
In State, Power, Socialism, Nicos Poulantzas conceptualized a state that materializes and concentrates power and displaces the class struggle from the economic to the political arena. In the past twenty years, much has changed. We argue that economic relations have been transformed by economic globalization, work reorganization, and the compression of space, time, and knowledge transmission through an information and communications revolution. Knowledge is far more central to production, and the locus of the relation between power and knowledge has moved out of the nation state that was so fundamental to Poulantzas' analysis. [source]

State estimation of networks with distributed generation

EUROPEAN TRANSACTIONS ON ELECTRICAL POWER, Issue 1 2007
Iņigo Cobelo
Abstract The nature and control of existing distribution networks limits the amount of distributed generation that can be connected. To increase the penetration of distributed generation a distribution management system controller (DMSC) can be used. The use of a DMSC requires a state estimator algorithm that provides an estimate of the network state in real time. In this paper, a state estimation algorithm based on the methods used on transmission networks is presented. The application of these methods into distribution networks requires existing measuring systems to be supplemented with the addition of new real-time measurements, and the use of load estimates.

Active resource management for the differentiated services environment

INTERNATIONAL JOURNAL OF NETWORK MANAGEMENT, Issue 3 2004
Manish Mahajan
This paper presents a mechanism for active resource management (ARM) in a differentiated services environment. While the differentiated services architecture and the bandwidth broker agent provide a mechanism for QoS management through resource reservation, this mechanism is based on a static provisioning of resources. As bandwidth requirement are typically dynamic, such a static reservation approach can either lead to wasted bandwidth or leave applications resource-starved. The active resource management approach presented in this paper addresses this problem by dynamically reallocating resources based on current network state and applications requirements. An implementation and evaluation of ARM using the NS-2 simulation toolkit is also presented.,Copyright Š 2004 John Wiley & Sons, Ltd. [source]

Static and adaptive routing in ISL networks from a constellation perspective

INTERNATIONAL JOURNAL OF SATELLITE COMMUNICATIONS AND NETWORKING, Issue 6 2002
Laurent Franck
Abstract This paper presents and evaluates different routing schemes in a constellation of non-geostationary satellites. Routing decisions may or may not take into account the state of the network. While taking into account the network state is likely to bring an improvement in both the network utilization and the quality of service, it also makes the routing architecture more complex. This paper proposes to evaluate the advantages and disadvantages of these different design approaches for routing. Copyright Š 2002 John Wiley & Sons, Ltd. [source]
