Cyber-Physical Systems (CPSs) play a critical role in our modern infrastructure due to their capability connect computing resources with physical systems. As such, topics such as reliability, performance, and security of CPSs continue receive increased attention from the research community. produce massive amounts data, creating opportunities use predictive Machine Learning (ML) models for perf...

With the rapid proliferation of cyber-physical systems (CPSs) in various sectors, including critical infrastructure, transportation, healthcare, and energy industry, there is a pressing need for robust cybersecurity mechanisms to protect these from cyberattacks. A system combination physical cyber components, security breach either component can lead catastrophic consequences. Cyberattack detec...

Let Xt be any d-dimensional continuous process that takes values in an open connected domain O in R. In this paper, we give equivalent formulations of the conditional full support CFS property ofXt inO. We use them to show that the CFS property of X inO implies the existence of a martingaleM under an equivalent probability measure such thatM lies in the > 0 neighborhood of Xt for any given unde...

The most frequent laboratory abnormalities in patients with congenital portosystemic shunts (CPSS) are microcytosis, hypoglycemia, hypoalbuminemia, hypoproteinemia, increased liver enzyme activities, decreased blood urea nitrogen (BUN) and urate crystalluria. The microcytosis is probably due to impaired iron transport. Hypoglycemia, hypoalbuminemia, hypoproteinemia and decreased BUN are partly ...

Low frequency oscillations (LFOs) have a dramatic effect on small signal stability of a power system. As power system started to operate near its stability limits, LFOs might lead to system instability. Power system stabilizers (PSSs) are provided with automatic voltage regulator to damp such effects. In this paper, an interval type-2 fuzzy logic power system stabilizer (IT2FLPSS) is proposed a...

A cyber-physical system (CPS) must continue to meet minimum performance requirements under extreme conditions, such as in the presence of security breaches. Existing security-aware techniques and analyses focus on pre-attack countermeasures and do not consider the impact of security attacks on real-time performance. We propose a post-attack node and load allocation algorithm for CPSs that must ...

To examine reciprocal relationships between “virtual world”-context cyberspace positive-psychological states (CPSs) and “real world”-context positive-psychological states (PSs), this study conducted a two-wave panel design with about two-semester interval on 251 Taiwan college freshmen and analyzed the data using cross-lagged structural equation modeling. The analytical results show that CPSs h...

A cyber-physical system (CPS) integrates a vast variety of static and mobile resources, including sensor and actuator networks, swarms of robots, remote-controlled vehicles, critical infrastructures, control and decision software, static data and just-in-time information from sensors, knowledge, data analytics and fusion software, eventdriven supply chains, and humans, and offers great potentia...

Advances in sensing, communications and data analytics have made it possible to construct virtual replicas of Cyber-Physical Systems (CPSs). Such replicas, known as digital twins, can principle inform decision making during operation evolution the systems they model. This short paper introduces ISoLA 2020/21 series papers on technology practice engineering twins for CPSs. The focus is relations...

This paper addressed the optimal policy selection problem of attacker and sensor in cyber-physical systems (CPSs) under denial service (DoS) attacks. Since have opposite goals, a two-player zero-sum game is introduced to describe between attacker, Nash equilibrium strategies are studied obtain actions. In order effectively evaluate quantify gains, reinforcement learning algorithm proposed dynam...
