    In this paper, we study shock propagation in cascade systems which can be a model of outage of power systems and a model to spread a new fashion. Although stabilities of the cascade systems have been studied in scientific area, we give a new problem in view of control theory and develop system analysis of the model. Concretely, a new stability analysis of the cascade model is conducted, and we dev... View full abstract»

    This paper proposes a normative decision analytic framework for the design of engineering systems. The approach distinguishes two main types of design enterprises: profit maximizing firms and federal government organizations. For a profit maximizing firm, the approach proposes that the firm should maximize the expected utility of total shareholder return. Within this framework, a fundamental axiom... View full abstract»

    Hospital readmission is an important quality of care indicator. It reflects challenges in quality of in-patient care and the difficulty of coordination of care after the transition back into the community. It is also a significant financial burden, especially as it relates to Medicare and Medicaid costs now and into the future. Chronic Obstructive Pulmonary Disease (COPD) is one of the leading cau...

    Aircraft are highly valuable assets and large budgets are spent in preventive and predictive maintenance programs. The application of PHM (Prognostics and Health Management) technologies can be a powerful decision support tool to help maintenance planners. The RUL (Remaining Useful Life) estimations obtained from a PHM system can be used in order to plan in advance for the repair of components bef... View full abstract»

    IT business value has been mostly conceptualized and examined based on pairwise relationships. This study argues that examining IT business value needs to consider the emergent properties generated from a firm as a whole system. Drawing on systems thinking and the resource-based view of the firm, this study develops a systemic model of IT business value and posits that IT impacts on firm performan... View full abstract»

    Model-based system engineering is an efficient approach to specifying, designing, simulating and validating complex systems. This approach allows errors to be detected as soon as possible in the design process, and thus reduces the overall cost of the product. Uniformity in a system engineering project, which is by definition multidisciplinary, is achieved by expressing the models in a common mode... View full abstract»

    Evaluation of the sophisticated safety critical systems is a tedious and time consuming process. This process has been undertaken manually, by experts and individuals, which increase the risk of human errors and ambiguities in understanding. We introduce an approach by integrating the mutation analysis and model checking. The mutation analysis cuts down the possibility of human errors, whereas mod... View full abstract»

    Despite the increased use of smartcards in many areas of everyday life the secure interoperability of these devices still remains a significant challenge. Common Criteria certification ensures the secure operation of a particular smartcard in a specific and closed environment and does not explicitly consider potential problems in more open environments where different types of smartcards and their...

    Much research has been performed that concentrates on providing processing throughput enhancements to existing algorithms. Many systems have performance requirements that constrain their volume and/or power consumption. For volume and power consumption constrained systems, throughput cannot be the only decision factor when selecting a computational engine. Typical studies can aid in the selection ...

    We present novel opportunistic interference aware scheduling (IAS) for dynamic channel allocation reuse to dynamically allocate new channels in unplanned networks. We introduce high levels of co-channel interferers with coordinated spatial signatures. We view this as likely system scenario for cognitive radio (CR) networks based upon IEEE 802.22 and moreover support smart grid, information network... View full abstract»

    The U.S. Defense acquisition system is notoriously resistant to fundamental reform and improvement. This case study examines the fundamental change in the technical architecture of the Navy's submarine sonar system and its acquisition enterprise. Many studies and recommendations for acquisition reform focus on process and incentive structures, few focus on architecture. Rather than focus on proces... View full abstract»
