The Concept of a Dual-Core PLC
IEC 61131-3-compliant engineering environments consist of IDE (integrated development environment) with language editors, compiler of source programs into binary code, and runtime for execution of the code. In a dual-core PLC proposed here, the cores run different projects cooperating by shared memory.

Testing in Microgrids
This entry covers testing in Microgrids. The most common strategies are described and some papers are critizied. Testing in Microgrids can be done in a variety of ways, among others digital simulation, co-simulation, Real-Time simulation (RTS) Hardware-In-the-Loop (HIL), Controller-Hardware-In-the-Loop (CHIL), Power-Hardware-In-the-Loop (PHIL) and emulators. To choose the desired strategy, the trade-off has to be made between the cost, test fidelity and test coverage. The entry is based on section in "Testing Smart Grid Scenarios with Small Volume Testbed and Flexible Power Inverter" by Milosz Krysik et al.

Technologies for Railway Track Maintenance
Inspection and repair interventions play vital roles in the asset management of railways. Autonomous mobile manipulators possess considerable potential to replace humans in many hazardous railway track maintenance tasks with high efficiency and increased asset utilization. Railway track maintenance technologies ranges from handheld devices to whole train, from manually pushed trolley to autonomous robots.

Supervised Learning Approaches for Mobile Robot Control
Machine learning (ML) is a branch of artificial intelligence that has been developing at a dynamic pace in recent years. ML is also linked with Big Data, which are huge datasets that need special tools and approaches to process them. ML algorithms make use of data to learn how to perform specific tasks or make appropriate decisions. ML approaches that have been applied to the task of mobile robot control are divided into the following: supervised learning, unsupervised learning, and reinforcement learning. The supervised learning methods are grouped into two main categories of regression and classification.

Steganography and Steganalysis in VoIP
The rapid advance and popularization of VoIP (Voice over IP) has also brought security issues. VoIP-based secure voice communication has two sides: first, for legitimate users, the secret voice can be embedded in the carrier and transmitted safely in the channel to prevent privacy leakage and ensure data security; second, for illegal users, the use of VoIP Voice communication hides and transmits illegal information, leading to security incidents. Therefore, in recent years, steganography and steganography analysis based on VoIP have gradually become research hotspots in the field of information security. Steganography and steganalysis based on VoIP can be divided into two categories, depending on where the secret information is embedded: steganography and steganalysis based on voice payload or protocol. The former mainly regards voice payload as the carrier, and steganography or steganalysis is performed with respect to the payload. It can be subdivided into steganography and steganalysis based on FBC (fixed codebook), LPC (linear prediction coefficient), and ACB (adaptive codebook). The latter uses various protocols as the carrier and performs steganography or steganalysis with respect to some fields of the protocol header and the timing of the voice packet. It can be divided into steganography and steganalysis based on the network layer, the transport layer, and the application layer. Recent research results of steganography and steganalysis based on protocol and voice payload are classified in this paper, and the paper also summarizes their characteristics, advantages, and disadvantages. The development direction of future research is analyzed. Therefore, this research can provide good help and guidance for researchers in related fields.

State-of-the-Art Battery Disassembly towards Automation
As the market share of electric vehicles continues to rise, the number of battery systems that are retired after their service life in the vehicle will also increase. This large growth in battery returns will also have a noticeable impact on processes such as battery disassembly. Due to the significantly increasing return volumes of traction batteries in the near future, a substantial increase in the degree of automation in battery disassembly is required, especially with regard to a stable recycling input flow.

Solar Photovoltaic Tracking Systems
Maximum solar power can be generated only when the Sun is perpendicular to the solar panel, which can be achieved only for a few hours when using a fixed solar panel system, hence the development of an automatic solar tracking system. Over the years, different solar tracking systems have been proposed and developed.

Software-Defined Protection, Automation, and Control in Power Systems
Power systems’ Protection, Automation, and Control (PAC) functionalities are often deployed in different constrained devices (Intelligent Electronic Devices) following a coupled hardware/software design. With the increase in distributed energy resources, more customized controllers will be required. These devices have high operational and deployment costs with long development, testing, and complex upgrade cycles. Addressing these challenges requires that a ’revolution’ in power system PAC design takes place. Decoupling from hardware-dependent implementations by virtualizing the functionalities facilitates the transition from a traditional power grid into a software-defined smart grid.

Smooth Coverage Path Planning for Unmanned Aerial Vehicles
Within the Industry 4.0 ecosystem, Inspection Robotics is one fundamental technology to speed up monitoring processes and obtain good accuracy and performance of the inspections while avoiding possible safety issues for human personnel. The robotics inspection of areas and surfaces employing Unmanned Aerial Vehicles (UAVs) has become an increasingly popular tool for agriculture. They offer a cost-effective and efficient way to monitor crops, assess crop health, and gather data for precision agriculture. Drones can cover large areas quickly and capture high-resolution images and other types of data that can be analyzed to identify issues and make informed decisions about crop management.
