Cyber-Physical Systems (CPSs) intertwine distributed controllers, which control physical processes. As these systems require guarantees on their stability and safety, there is a need for systematic methods integrated safety analysis of CPSs. To this end, we have developed novel approach the design resilient CPSs that combines formal theory. Our framework suitable CPS with real-time requirements...

Cyber-Physical Systems (CPSs) are a new study area that has the potential to bring together physical and digital worlds. Researchers in this focus on ways which CPSs communicate with one other. Features requirements for data transfer CPSs, also related unsolved issues, covered paper. The IEEE 802.11 b/g protocols were used construct CPS solution ambient sensing (humidity temperature). Wireless ...

The performance of two-microphone coherence based methods degrades if two captured noises are correlated. The Cross Power Spectrum Subtraction (CPSS) is an adapted coherence method for noise correlated environments. In this paper, we propose a new technique for estimation of speech cross power spectrum density and we exploit it in CPSS. The proposed speech enhancement method is evaluated as a s...

Traditional concepts of managing product innovation are not suitable for innovation in complex product systems (CPSs). This paper argues that firms developing and integrating the components of CPSs need specific competence for managing such projects. A framework for evaluating a firm’s competence in CPS innovation is developed that covers managing the integration of internal and external key re...

Modern cyber physical systems (CPSs) are becoming more and more vulnerable to security related attacks, due to the growing number of interconnectivity and standardized communication channels. This evolution make the traditional approaches considering the safety and security domains as two disjunctive areas obsolete. In this paper we propose state/event fault tree for modeling and analyzing the ...

Cyber-Physical Systems (CPSs) engineering profoundly relies on modeling methods to represent the system and study operation cybersecurity of CPSs. The a CPS is result collaboration between Information Technology (IT) Operational (OT) components. While OT focuses system's process physics, emphasis IT information flow. Consequently, different models are utilized various aspects CPSs, which...

HEALTH ISSUE: Canada's standard of perinatal care ranks among the highest in the world, but there is still room for improvement, both in terms of regional differences in care and global comparisons of approaches to care in Canada and elsewhere. Data from the Canadian Perinatal Surveillance System (CPSS) was used to evaluate morbidity and mortality among mothers and infants. KEY FINDINGS: Matern...

The nonlinearity in the pharmacokinetics of the cyclopentapeptide endothelin antagonist BQ-123 was studied. Both the total body clearance and tissue-to-plasma concentration ratio (Kp) were investigated in rats under a wide range of steady-state plasma concentrations (Cpss) obtained by changing the intravenous infusion rate of BQ-123. The total body clearance was constant up to a Cpss level of 5...

Cyber-physical systems (CPS) are at a crossroads. Typical CPSs with multi-loop control consisting of device controllers, plant-level distributed control, and system-wide SCADA components are pushed (see Figure 1 below) by market forces to:  Connect many diverse (e.g., control and business) systems leading to an internetworked system of systems spanning wide geographic areas,  Use off-the-shel...
