Cyber-physical systems (CPSs) are deemed as the key enablers of next generation applications. Needless to say, the design, verification and validation of cyber-physical systems reaches unprecedented levels of complexity, specially due to their sensibility to safety issues. Under this perspective, leveraging architectural descriptions to reason on a CPS(More)
By focussing on Cyber Physical Systems (CPS), this paper investigates how component-based principles and practices are used and support the activity of architecting CPS. For doing so, by running a systematic process, we selected 49 primary studies from the most important publishers search engines. Those papers have been analyzed and their contents(More)
Least squares support vector machines (LS-SVM) based on a group of different kernel functions (Linear-Polynomial-Radial Basis Function- Exponential Radial Basis Function) for modeling nonlinear systems is introduced in this paper. A method for selecting the hyperparameters of LS-SVM is presented in details for both the regularization parameter (γ)(More)
Context: Security has become a major concern for modern Cyber-Physical Systems (CPS), due to their distributed, sensing, actuating, and always connected nature. A considerable number of security principles and practices have been defined by the security communities and are being implemented in architecting secure CPS. Objective: The main question we are(More)
<i>Context</i>: Cyber-physical systems (CPS) seamlessly integrate computational and physical components. Adaptability, realized through feedback loops, is a key requirement to deal with uncertain operating conditions in CPS. <i>Objective</i>: We aim at assessing state-of-art approaches to handle self-adaptation in CPS at the architectural level.
