Cultural eutrophication in estuaries and other coastal systems has increased over the last 50 yr. Some recently proposed strategies to reverse this trend have included the restoration of bivalve suspension feeders as an ecological tool for reducing phytoplankton biomass. The ecological benefits accruing from such bivalve restoration will be dependent on the characteristics of the estuary, as we...
A methodology is presented for integrating effective-bandwidth-based routing for QoS-sensitive traffic and datagram routing of the best-effort traffic. To prevent excessive delays of best-effort traffic in a network domain, we develop (1) a constraint, stated in the form of a residual link bandwidth, and (2) a cost function for application to routing of QoS connections. Link-based and path-base...
In this paper we study the topic of signal restoration using complexity regularization, quantifying the compression bit-cost of the signal estimate. While complexity-regularized restoration is an established concept, solid practical methods were suggested only for the Gaussian denoising task, leaving more complicated restoration problems without a generally constructive approach. Here we presen...

Absrracf This paper develops a coarse-grain parallel genetic algorithm for solving a service restoration problem in electric power distribution systems. Power utility performs service restoration in order to restore out-ofservice areas at fault. Developing effective service restoration procedure is a cost-effective approach to improve service reliability and to enhance customer satisfaction. Th...
Recent development in optical networking employing wavelength-division-multiplexing (WDM) fulfills the high bandwidth demand applications. Failure of such networks, leads to enormous data and revenue loss. Design a low cost survivable WDM network is always an interesting and difficult process. In this paper we present link-path model for capacity allocation and calculate blocking probability in...
This paper presents the survivability issues relevant to ATM group communications and outlines the tradeo s between restoration techniques that can be extended from circuit-switched communications. Current models proposed by the ATM Forum for group communications (VC Mesh and Multicast Server) are compared and restoration techniques for all possible single fault scenarios are examined. It is co...
Ecological restoration projects have traditionally focused on vegetation as both a means (seeding, planting, and substrate amendments) and ends (success based upon primary productivity and vegetation diversity). This vegetation-centric approach to ecological restoration stems from an historic emphasis on esthetics and cost but provides a limitedmeasure of total ecosystem functioning and overloo...
