Geopolymers in nuclear waste storage and immobilization: mechanisms, applications, and challenges
According to the latest report by the International Atomic Energy Agency (IAEA), nuclear facilities generate over 30 tons of high-level radioactive waste and 300,000 tons of medium-level waste annually, highlighting the need for secure immobilization methods to safeguard environmental and public health. Cementitious materials such as ordinary Portland cement (OPC) and other materials are commonly […]

Finite-dimensional adaptive observer design for linear parabolic systems with delayed measurements
New finite-dimensional adaptive observers are proposed for uncertain heat equation and a class of linear Kuramoto–Sivashinsky equation (KSE) with local output. The observers are based on the modal decomposition approach and use a classical persistent excitation condition to ensure practical exponential convergence of both states and parameters estimation. An important challenge of this work is […]

A multi-agent system simulation of job shop scheduling with human consideration: A comparative analysis of AGVs and AIVs
The manufacturing landscape is undergoing a paradigm shift towards Industry 5.0, emphasizing human-centricity in a collaborative environment between humans and robots. In this context, the job shop scheduling problem (JSSP) remains a critical aspect of workshop management, optimizing task sequencing to minimize the overall completion time (makespan). Traditionally, autonomous and guided vehicles (AGVs) have been […]

Sampled-data high gain observers for dynamic state estimation in power system
A novel dynamic state estimator is proposed for a class of synchronous generators. The proposed observer is based on high gain principle and provides an accurate estimations of all states of the systems. A sampled-data version which can works with relatively low sampling frequency is also provided. Our algorithms are vali- dated in simulations and […]

Predictive Maintenance for Smart Buildings: Balancing QoS and Cost Efficiency
The rapid advancement of sensing technologies and connectivity has revolutionized predictive maintenance (PdM), particularly for smart buildings (SB). Despite these advancements, implementing data-driven approaches faces challenges, mainly due to scarce failure data and the SB systems complexity. In this paper, we propose a cooperative multi-agent reinforcement learning (RL) based approach to address these challenges in […]

TCAD-Based Analysis on the Impact of AlN Interlayer in Normally-off AlGaN_GaN MISHEMTs with Buried p-Region
With the growing demand for more efficient power conversion and silicon reaching its theoretical limit, wide bandgap semiconductor devices are emerging as a potential solution. For instance, Gallium Nitride (GaN)-based high-electron-mobility transistors (HEMTs) are getting more attention, and several structures for the normally off operation have been proposed. Adding an AlN interlayer in conventional AlGaN/GaN […]
