Effective path-finding in complex environments is pivotal for numerous domains, such as robotics and gaming. The A* algorithm has been widely employed to balance completeness and optimality. However, in complex post-disaster environments, the traditional A* algorithm often fails to successfully perform path planning due to many obstacles and altitude changes. This paper presents an A* implementation tailored for navigating environments with obstacles and varying terrain elevations, aiming to deal with this problem. The algorithm could efficiently find optimal paths by considering obstacle avoidance and height differences. The results shows that compare to A* algorithm, the enhanced A* algorithm has better performance in terms of path length and success rate. Especially in high-complexity environments, the enhanced program can still maintain a search success rate of more than 95% with an ideal path length. The algorithm's adaptability and effectiveness in diverse environments make it a valuable tool for real-world navigation challenges. This paper contributes to understanding intelligent navigation techniques and their applications in complex post-disaster environments.

Grounding systems play a crucial role in ensuring the integrity and safety of people and equipment in the power electrical system. However, the conventional methodology for evaluating their operational state is based on measurements of grounding resistance or impedance, which alone do not provide accurate information on the operational status of the grids. Conventional measurements are invasive and not capable of identifying localized problems such as corrosion or conductor breakage. In this context, this study proposes a new approach for monitoring the state of grounding systems through the analysis of transient signals. The effectiveness of the proposed approach is evaluated through case studies based on computer simulations using finite element method. The main objective is to develop a methodology that allows identifying defects in grounding systems based on the analysis of transient response and electromagnetic signal reflection parameters. Next, it is intended to use the Wavelet transform to enable identification of patterns relevant to fault detection. The results of the case studies conducted allowed determining the influence of variations in soil resistivity and permittivity on signal propagation and reflection, as well as the need for methodological adaptations to overcome computational limitations. The existence of distinct patterns associated with conditions of intact and defective grounding conductors was also found. Thus, the approach proposed in this work can contribute significantly to the effective monitoring of grounding systems. In the continuation of the research, it is intended to analyze more complex geometries and develop neural networks for classifying characteristic signal signatures associated with normal and defective states.

This paper reports the progress of an ongoing project "Emergency Evacuation System for Disabilities in Wheelchair" sponsored by engineering Projects in Community Service (EPICS) of ieee. The project aims to develop an advanced mechatronic system that will be used to evacuate a disabled in a wheelchair from a high-rise building with the minimal assistances from caregivers. In this paper, the needs to develop such a system are discussed thoroughly, existing evacuation techniques are investigated to identify their limitations, a new evacuation system is conceived to enhance safety, flexibility, and efficiency of existing techniques. The project also explores a new way to support students' collaborations in designing a complex mechatronic system effectively. Model-Based System engineering (MBSE) is adopted in designing key system components with minimized couplings with others, and the case study development has evidenced the systematism and effectiveness of MBSE in dealing with couplings, complexity, and scalability of complex mechatronic systems.

Rollups are a type of blockchain network that derives state from another blockchain network. These systems are complex pieces of middleware that provide a development platform for decentralized applications but also depend on another blockchain network to function. They involve a number of components, some of which execute off-chain (possibly on specialized hardware), and some of which are implemented via smart contracts. They are expected to handle millions of dollars in cryptocurrencies and operate at scale with strong liveness guarantees. These properties result in a unique set of requirements for these systems. In this document, we report on the requirements engineering challenges related to building such a system from first-hand experience.
