A new formulation of the maximal common subgraph problem (MCSP), that is implemented using a two-stage Hopfield neural network, is given. Relative merits of this proposed formulation, with respect to current neural network-based solutions as well as classical sequential-search-based solutions, are discussed.
The current level of unpredictability associated with the traditional approach for disk service is unacceptable to realtime applications. Consequently, early real-time applications avoided the use of disk drives and operated entirely in main memory. In order to significantly reduce this variability, we should have a better understanding of its cause(s), and(More)
The Integrated Modular Avionics (IMA) approach can achieve lower overall hardware costs and reduced level of spares by getting multiple applications that have traditionally been implemented using separate, federated units to share hardware resources. However, the IMA approach also brings new challenges that did not exist in the federated setup. Avoiding(More)
The trend in implementing today’s embedded applications is toward the use of commercial-off-the-shelf open architecture. Reducing costs and facilitating systems integration are among the motives for that trend. The use of the VME bus becomes very common in many industrial applications. The VME bus attracts developers with its rigorous specifications,(More)
This paper summarizes our experiences restructuring a core portion of our required courses for majors. Internal and external reviews of our program highlighted areas of concern in our "systems core," including inconsistent student outcomes, missing required material, and inadequate opportunities for programmatic assessment. To fix these problems, we(More)
The VME bus has been widely used in embedded systems due to its rigorous design, stable specifications, and the fact that it has enjoyed a strong support from multiple vendors. However, the VME bus still lacks some features that are essential to safety-critical systems, such as avionics. In this paper, we address the issue of lacking the capability of fault(More)
