Safety and Security Issues in the IoT Domain
The Internet of Things (IoT), which is developing quickly, has continued to provide humanity with many advantages, including many applications crucial for security and safety. The assurance that IoT devices will not pose a risk to people or the environment is necessary to realise the full potential of IoT applications, particularly in high-consequence areas. To develop safe, secure, and dependable IoT systems, it is necessary to comprehend a wide range of safety and security issues across the IoT's architectural frameworks and levels. As a result, among other attributes of dependable IoT systems, this research outlines safety and security features.

Cyber-Physical Systems with Process-Oriented Paradigm
Process Oriented Programming (POP) is a programming paradigm based on the concept of "processes" that determine the response (outputs) of a reactive system based on events (states of internal and external variables, timeouts). A process-oriented program is a set of interacting processes that can change their behavior (reaction to events), start and stop other processes, and be executed in parallel. The languages created within the framework of POP (e.g. Reflex, IndustrialC, poST) fit very well for specification various control algorithms, which can consist of hundreds and thousands of processes. In addition to the fact that process-oriented programs structurally and conceptually correspond to the technological description of the plant under control, they also have the following remarkable property. In process-oriented algorithms, the use of data is usually local, limited to one or more processes.

Topology Designs for Data Centers
The adoption of simple network topologies allows for an easier way to forward packets. On the other hand, more complex topologies may achieve greater performance, although network maintenance may become harder. Hence, a balance between performance and simplicity is a convenient point when choosing a data center design. Therefore, some topology designs for data centers are going to be proposed; these are classified into tree-like and graph-like architectures. With respect to the former, a hierarchical switching layout interconnects all nodes, thus showing the form of an inverted tree within multiple roots, where nodes are the leaves of such a tree. Regarding the latter, nodes are directly interconnected to each other, hence no switch is involved in the design.

Fog-Based IoT Platform Performance Modeling and Optimization
A fog-based IoT platform model involving three layers, i.e., IoT devices, fog nodes, and the cloud, was proposed using an open Jackson network with feedback. The system performance was analyzed for individual subsystems, and the overall system was based on different input parameters. Interesting performance metrics were derived from analytical results. A resource optimization problem was developed and solved to determine the optimal service rates at individual fog nodes under some constraint conditions.

Distributed and Localisation System for Crude Oil Pipelines
Crude oil leakages and spills (OLS) are some of the problems attributed to pipeline failures in the oil and gas industry’s midstream sector. Consequently, they are monitored via several leakage detection and localisation techniques (LDTs) comprising classical methods and, recently, Internet of Things (IoT)-based systems via wireless sensor networks (WSNs).
