The advent of multimedia ushers forth a growing class of applications that must manipulate digital audio and video within well-defined timeliness requirements. Existing processor schedulers are inadequate in supporting these requirements. They fail to allow the integration of these continuous media computations with conventional interactive and batch activities. By observing that all tasks do i...

This paper develops and tests procedures for identifying lead analysts based on the timeliness of analyst forecast revisions, the trading levels associated with these revisions, and forecast accuracy. Our framework provides an objective assessment of analyst quality that differs from the standard approach that uses survey evidence to rate analysts. Using a sample of equity analysts, we find tha...

In this paper, we present a systems engineering methodology for constructing certifiable realtime distributed systems. In the proposed approach, an architectural and algorithmic solution to an application problem is designed by considering the “weakest” models including the weakest asynchronous computational model and multimodal arrival model. Furthermore, timeliness properties are described us...
