In this paper we introduce the General Adaptable Metric Execution Tool and Environment (GAMETE) to aid the design, measurement, and analysis of cyber-physical systems (CPSs). GAMETE is a general and extensible environment for evaluating and computing metrics associated with the performance and complexity of CPS designs. GAMETE supports a wide array of metrics that it generates over simulation a...

Cyber Physical Systems (CPSs) are becoming not only increasingly complex but also increasingly important. These systems have evolved from self-contained monolithic systems operating in a well-defined environment, to large-scale Cyber-Physical Systems including multiple interacting components. In this paper we will refer to both as CPSs. Due to the inherent complexity of the physical environment...

Cyber-physical systems (CPSs) are service systems that connect a product’s physical and computational elements through telecommunication networks. Typically, the processes in CPSs are executed on this physical and computational infrastructure. As the developing of new CPS is costly, testing and validating a CPS’s design at an early stage of development is desirable in order to avoid potential b...

Cyber physical systems (CPSs) are pervasive in our daily life from mobile phones to auto driving cars. CPSs are inherently complex due to their sophisticated behaviors and thus difficult to build. In this paper, we propose a framework to develop CPSs based on a model driven approach with quality assurance throughout the development process. An agent-oriented approach is used to model individual...

Strains 6, 15, 98, 110, and 145 of Cryptococcus neoformans serotype A vary in capsule size, animal virulence, and susceptibility to in vitro phagocytosis. The isolated capsular polysaccharides (CPSs) differ in monosaccharide composition ratios and molecular size, as determined by gel filtration. The purpose of this investigation was to characterize the binding of CPSs to capsule-free mutants of...

OBJECTIVE To compare long-term survival and quality of life data in dogs with clinical signs associated with a congenital portosystemic shunt (CPSS) that underwent medical or surgical treatment. DESIGN Prospective cohort study. ANIMALS 124 client-owned dogs with CPSS. PROCEDURES Dogs received medical or surgical treatment without regard to signalment, clinical signs, or clinicopathologic ...

The integration of computer-centric control and physical systems is becoming more entrenched, as we see these cyber-physical systems (CPS) appearing in a wide variety of systems including medical systems, industrial monitoring, agriculture, avionics, amongst others. However, we see the following limitations to the wide-spread adoption of CPSs, namely inadequate information and data capabilities...

The emergence of Cyber-Physical Systems (CPSs) heralds the ubiquitous and autonomous globally interconnected networks of embedded devices with their own means of interaction with the physical environment. The complex interactions with the physical environment significantly increase security risks. Especially, for mission-critical CPSs, sensitive data are closely related to security issues and a...

Power system stabilizers (PSSs) must be capable of providing appropriate stabilization signals over abroad range of operating conditions and disturbances. The main idea of this paper is changing aclassic PSS (CPSS) to an adaptive PSS using genetic algorithm. This new genetic algorithm based onadaptive PSS (GAPSS) improves power system damping, considerably. The controller design issue isformula...
