The Slow and The Furious? Performance Antipattern Detection in Cyber-Physical Systems

Cyber-Physical Systems (CPSs) have gained traction in recent years. A major non-functional quality of CPS is performance since it affects both usability and security. This critical quality attribute depends on the specialized hardware, simulation engines, and environmental factors that characterize the system under analysis. While a large body...

The Intelligent Built-Environment as Cyber-Physical System

Discussions of intelligence in the built-environment began in the late 1960s and early 1970s [1]–[7]. They belonged to a broader technical and technological discourse, engaged across a variety of domains and disciplines, to explore potential opportunities entailed by the Information Age. During this nascent period, and partly due to the novelty...

Attack Graph Model for Cyber-Physical Power Systems Using Hybrid Deep Learning

Electrical power grids are vulnerable to cyber attacks, as seen in Ukraine in 2015 and 2016. However, existing attack detection methods are limited. Most of them are based on power system measurement anomalies that occur when an attack is successfully executed at the later stages of the cyber kill chain. In contrast, the attacks on the Ukrainian...

Continuous Integration and Delivery practices for Cyber-Physical systems: An interview-based study

Continuous Integration and Delivery (CI/CD) practices have shown several benefits for software development and operations, such as faster release cycles and early discovery of defects. For Cyber-Physical System (CPS) development, CI/CD can help achieving required goals, such as high dependability, yet it may be challenging to apply. This...

Perspectives on Future Power System Control Centers for Energy Transition

Today's power systems are seeing a paradigm shift under the energy transition, sparkled by the electrification of demand, digitalisation of systems, and an increasing share of decarbonated power generation. Most of these changes have a direct impact on their control centers, forcing them to handle weather-based energy resources, new...

Critical Components Identification for Cyber-Physical Power Systems Considering Time-Varying Operational States

The security issues of Cyber-Physical power Systems (CPS) have attracted widespread attention from scholars. Vulnerability assessment emerges as an effective method to identify the critical components and thus increase the system resilience. While efforts have been made to study the vulnerability features of power systems under the occurrence...

Cyber Attacks on Protective Relays in Digital Substations and Impact Analysis

Power systems automation and communication standards are crucial for the transition of the conventional power system towards a smart grid. The IEC 61850 standard is widely used for substation automation and protection. It enables real-time communication and data exchange between critical substation automation devices. IEC 61850 serves as the...

System-level feature-based modeling of cyber-physical systems: A theoretical framework and methodological fundamentals

Cyber-physical systems are complex trans-disciplinary systems. Designing this kind of systems requires cooperation of several groups of experts with various backgrounds such as mechatronics and robotics, software engineering, data management, knowledge engineering, system on a chip, embedded systems, humans and systems interaction, and social...

Design-to-Robotic-Operation Principles and Strategies as Drivers of Interior Environmental Quality

This paper presents a high-resolution intelligence implementation based on Design-to-Robotic-Operation (D2RO) principles and strategies specifically employed to attain and to sustain Interior Environmental Quality (IEQ) within a dynamic built-environment. This implementation focuses on two IEQ-parameters, namely illumination and ventilation; and...
