This work presents statistical anomaly detectionmethods for cyber-physical systems using the Secure Water Treatment dataset, a scaled down version of a real-world industrial water treatment plant. We consider a critical sensor signal, the water level indicator LIT301, and set up two corresponding models for detecting cyber-attacks - a sliding window Z-score outlier detection, and an autoregressive integrated moving average time-series forecasting model of order (3,0,5).

This article presents a new scalable system for automated modeling of physical processes and experiment management based on microservice architecture and cloud technologies. The proposed platform addresses the growing need for flexible, cost-effective, and highly scalable computational solutions for physical research. The system utilizes Amazon Web Services cloud infrastructure with containerized microservices to provide automated resource allocation, experiment orchestration, and laboratory equipment integration.

The application of information technologies particularly decision support systems in laboratory diagnostics and healthcare in general is becoming increasingly significant. This article presents an analysis of the implementation of a risk-based approach within management system processes and the operational activities of medical laboratories. Approaches to the identification of innovative risks in medical laboratories are substantiated in accordance with the requirements of international standards governing laboratory practice.

The measurement of arterial hemoglobin oxygen saturation, pulse, and blood pressure was presented. A review of methods for measuring arterial hemoglobin oxygen saturation based on photoplethysmography was provided. The architecture of the hardware and software platform of a cyber-physical system for the primary processing and transmission of information signals, based on a microcontroller with hardware encryption and a Bluetooth module for transmitting encrypted data to a mobile device and a remote server, was considered.

The design of modern Cyber-Physical Systems (CPS) connects physical and digital realms from cloud systems to edge devices. Microservice architecture has been widely used for IT solutions and emerges as a promising approach for supporting CPS that are more efficient, adaptable, and interconnected. However, there is an increasing need to improve the availability, reliability, and resilience of microservice systems according to the needs. This paper summarizes the challenges and drawbacks of microservice architecture used for CPS.

The improvement of homophonic encryption using the well-known Z408 cipher as an example has been examined in this article. Their problems to further correct the main shortcomings of this type of encryption have been analyzed. In the practical part, an encryption system similar to Z408 has been created and the complexity of the language analysis for this cipher has been increased. The correlation data of the number of alternative characters has been used to improve the transmission of encrypted data depending on the load of the device.

An autonomous cyberphysical adaptive system of controlled purification and control of water composition has been considered. Theoretical analysis and experimental studies of the functioning of the components of the proposed system of controlled purification and control of water composition has been performed. The proposed installation is designed to implement the technology of self-regulating system. When using intelligent digital means, it becomes an autonomous cyberphysical adaptive system of controlled purification and control of water composition.

Authors have analyzed the current state of cloud calculations and discovered the necessity of Application Programming Interface (API) usage in some of the cyber- physical systems (CPhS). The expediency of creating tools to reduce service time of Application Programming Interface requests and effective synchronization of the local and cloud database has been established. The authors clarified one of the main features of data replication. The expediency of using counter generations in the replication process instead of using system timer has been justified.
