Particle Swarm Optimisation in Internet of Things
The internet of things, a collection of diversified distributed nodes, implies a varying choice of activities ranging from sleep monitoring and tracking of activities, to more complex activities such as data analytics and management. With an increase in scale comes even greater complexities, leading to significant challenges such as excess energy dissipation, which can lead to a decrease in IoT devices’ lifespan. Internet of things’ (IoT) multiple variable activities and ample data management greatly influence devices’ lifespan, making resource optimisation a necessity. Existing methods with respect to aspects of resource management and optimisation are limited in their concern of devices energy dissipation.

Micro-Grid Communication Protocols and Standards
A microgrid is a comprehensive system that includes energy storage, different energy sources, and loads within a certain boundary. It functions seamlessly, whether it is linked to, or works independently from, the main electrical grid, ensuring a consistent power supply. Microgrids consist of distributed energy resources (DER) and loads, which may be located in one place or spread throughout an electrical distribution network.

Faults in a Photovoltaic System
Photovoltaic systems are prone to breaking down due to harsh conditions. In photovoltaic systems, various types of faults can cause power loss in some way. To improve the reliability of these systems, diagnostic methods using Machine Learning (ML) have been developed.

Centralized vs. Decentralized Electric Grid Resilience
Escalating events such as extreme weather conditions, geopolitical incidents, acts of war, cyberattacks, and the intermittence of renewable energy resources pose substantial challenges to the functionality of global electric grids. Consequently, research on enhancing the resilience of electric grids has become increasingly crucial. Concurrently, the decentralization of electric grids, driven by a heightened integration of distributed energy resources (DERs) and the imperative for decarbonization, has brought about significant transformations in grid topologies.

Multilevel Inverters in  Battery Electric Vehicles
All electric vehicles are the only way to decarbonize transport quickly and substantially. Although multilevel inverters have already been used in some transportation modes, they are rarely used in road transportation, especially in light-duty passenger battery electric vehicles (BEVs). With the transition to a high 800-V DC link to extend the driving range and enable extreme fast charging, the possibility of using multilevel inverters in commercial light-duty passenger BEVs becomes feasible. Higher efficiency, higher power density, better waveform quality, lower switching frequency, the possibility of using low-rated switches, and inherent fault tolerance are known advantages of multilevel inverters that make them an efficient option for replacing 2-level inverters in high DC link passenger BEVs.

Interconnected Smart Transactive Microgrids
Smart transactive microgrids (STMs) are defined as specialized microgrid systems that can autonomously regulate the generation, storage, and consumption of electricity among a network of users within a localized area. They enhance both economic and environmental efficiency by employing real-time pricing mechanisms and digital technologies. In a more general sense, STMs can be considered as a subset of microgrids (MGs) that incorporate principles of transactive energy, along with energy and information sharing among consumers. The United States Department of Energy (DOE) initially conceptualized this idea in the early 2000s, inaugurating the Grid Wise program in 2005 to modernize the national electric grid, which included the advancement of transactive energy systems.

Denoising Techniques for High-Performance MEMS Microphones
The MEMS (Micro-Electro-Mechanical Systems) microphone is a representative device among the MEMS family, which has attracted substantial research interest, and those tailored for human voice have earned distinct success in commercialization. With the advancement of microphone technology and the market, microphones have become carriers for various intelligent applications, therefore demanding higher criteria in noise suppression. For instance, a hearing aid should suppress ambient noise while delivering relevant sounds to the user. Additionally, in specific environments, the noise performance of microphones is crucial for communication and intelligent voice-related needs such as voice activation and speech recognition.

Contacts at the Nanoscale
Contact scaling is a major challenge in nano complementary metal–oxide–semiconductor (CMOS) technology, as the surface roughness, contact size, film thicknesses, and undoped substrate become more problematic as the technology shrinks to the nanometer range. These factors increase the contact resistance and the nonlinearity of the current–voltage characteristics, which could limit the benefits of the further downsizing of CMOS devices.
