Many WDM architectures are based onJixed wavelength channels which require the lasers to be tuned to their channels accurately. Achieving this task is difJicult and costly especially in the distributed environments. Robust WDM is an approach that tolerates large laser wavelength variations, due to temperature drifts and manufacturing tolerances. A(More)
WDM networks in general depend on transmitters and receivers that are precisely tuned to predetermined fmed wavelengths. Robust WDM is an approach aimed at relaxing manujkcturing and operating wavelength tolerance requirements, which will lead to cost effective implementations. In this approach, connections are based on dynamically selected wavelengths as(More)
The research interest of the dissertation focuses on the analysis of the effects of learning laboratories on the control of inventories. Learning laboratories aggregate a simulation game (or management flight simulator); such as the supply net game developed in the thesis, and a systems thinking intervention based upon mental model elicitation methods, for(More)
WDM networks depend on predetermined, fixed wavelength channels, requiring highly stable lasers and tunable filters. Robust WDM networks, based on dynamically selected wavelengths, relax manufacturing and operating wavelength tolerance requirements leading to low-cost implementations. A node dynamically selects a currently unused wavelength for(More)
Many organizations today use a bell-curve for performance evaluation process. They reward a small percentage of top performers, encourage a large majority in the middle to improve, and lay-off the bottom performers. Companies believe that such pay-for-performance system encourages employees to perform better. The question we explore in this paper is: does(More)
This research analyzes how a telecommunications regulator can balance regulation with innovation, at a reasonable cost. This question has gained critical importance for telecom regulators as the unregulated Internet technologies such as voice and video over Internet disrupt the regulated traditional technologies such as telephony and television and the(More)
During the mid-1960s, India came to the brink of an acute food crisis in the midst of heavy dependence on food imports. A period of rapid agricultural modernization that followed, known as Green Revolution, transformed India from a net importer of food into an exporter. Although an appropriate response for abating the impending starvation, the Green(More)
