Surveillance can be based, in some change-point detection problems, on a sequence of invariant statistics. Gordon and Pollak (1997) prove that, under certain conditions, the Average Run Length (ARL) to false alarm of invariance-based Shiryayev-Roberts detection schemes is asymptotically the same as that of the dual classical scheme that is based on the original sequence of observations. In this...

Software engineering development is crucial for industrial and commercial applications as these systems are required to operate in increasingly complex, distributed, open, dynamic, unpredictable, and inherently highly interactive environments. This work is being motivated by the need to engineer complex systems with autonomous entities, to manage their inherent complexity during analysis, desig...

To study the design, control and energetics of autonomous dynamically stable legged machines we have built a planar one-legged robot, the ARL Monopod. Its top running speed of 4.3 km/h (1.2 m/s) makes it the fastest electrically actuated legged robot to date. We adapted Raibert's control laws for the low power electric actuation necessary for autonomous locomotion and performed a detailed energ...

This paper presents general strategies for cyber war gaming of Cyber-Physical Systems (CPSs) that are used for cyber security research at the U.S. Army Research Laboratory (ARL). Since Supervisory Control and Data Acquisition (SCADA) and other CPSs are operational systems, it is difficult or impossible to perform security experiments on actual systems. The authors describe how table-top strateg...

Count data appears widely in finance, biomedical science, psychology, actuarial insurance, road safety and many other areas of life, it is often multivariate. In this paper, we consider using the multivariate exponentially weighted moving average (MEWMA) control chart method to monitor count under assumption Poisson distribution, which derived by He [1] from another form gamma distribution. We ...
