“…Post testing, these circuits will integrate into a wearable IoT node that employs a nRF52 family communication chip, aiming to monitor presence and location of persons within a facility. Moreover, this device could prolong the lifespan of the stress-monitoring node in steel infrastructures, as discussed in the author's prior work [58]. This node currently utilizes a PIC 24FV family controller.…”

This article presents research about a hybrid power system dedicated to Internet of Things (IoT) nodes. As an introduction, performance tests of the harvesters, that is, a 40 × 40 mm Peltier cell based on Bi2Te3 and three solar cells, monocrystalline, polycrystalline, and amorphous, are presented. The study established the dependence of the effect of generated power on the load resistance. Thus, it states how the internal resistance of the harvesters changes. Following the above tests, a complete power unit with a single harvester and an LTC3108 conversion circuit, as well as an energy buffer in the form of a 1 mF supercapacitor, were built and tested. The unit with a thermoelectric generator generated power from 14 to 409 µW. The unit with a 65 × 65 mm polycrystalline cell generated power from 150 to 409 µW. Next, a hybrid system was built and tested with both of the aforementioned harvesters, which generated power from 205 to 450 µW at 2000 lx illumination and a temperature difference of 20 °C for the thermoelectric generator claddings.

Multi-Agent Systems (MAS) have been seen as an attractive area of research for civil engineering professionals to subdivide complex issues. Based on the assignment’s history, nearby agents, and objective, the agent intended to take the appropriate action to complete the task. MAS models complex systems, smart grids, and computer networks. MAS has problems with agent coordination, security, and work distribution despite its use. This paper reviews MAS definitions, attributes, applications, issues, and communications. For this reason, MASs have drawn interest from computer science and civil engineering experts to solve complex difficulties by subdividing them into smaller assignments. Agents have individual responsibilities. Each agent selects the best action based on its activity history, interactions with neighbors, and purpose. MAS uses the modeling of complex systems, smart grids, and computer networks. Despite their extensive use, MAS still confronts agent coordination, security, and work distribution challenges. This study examines MAS’s definitions, characteristics, applications, issues, communications, and evaluation, as well as the classification of MAS applications and difficulties, plus research references. This paper should be a helpful resource for MAS researchers and practitioners. MAS in controlling smart grids, including energy management, energy marketing, pricing, energy scheduling, reliability, network security, fault handling capability, agent-to-agent communication, SG-electrical cars, SG-building energy systems, and soft grids, have been examined. More than 100 MAS-based smart grid control publications have been reviewed, categorized, and compiled.

Design and Application of a Construction-Operation Monitoring System for Spoke-Free Ferris Wheels

The construction and operation monitoring of a spoke-free Ferris wheel is challenging because of its novel shape and inherently complex environment. It necessitates an innovative monitoring system that can be used in both construction and operation stages because both the traditional and single monitoring system are not applicable to this structure at the same time. In this study, a practical construction-operation monitoring system for a spoke-free Ferris wheel was developed and applied to the White-wave River Ferris Wheel. In the proposed monitoring system, the overall design, architecture of the system, and the sensors and monitoring data-sharing contents at each stage of their implementations are discussed in detail. Finite element analysis was applied to determine the monitoring parameters and the sensor’s positions. Customized energy-efficient wireless sensor nodes were employed and data transmissions from the sensors to the remote monitoring servers were conducted through comprehensive communication (cable, wireless, and internet). The monitoring data during construction indicate that the removal of temporary support will cause significant changes to the stress and displacement of the structure. A synchronous and hierarchical removal scheme can effectively avoid such rapid changes. The data at the operation stage indicate that both the displacement at the top and the stress at the bottom parts of the White-wave River Ferris Wheel structure are sensitive to temperature changes. The influence of temperature on the structure stress can reach up to 41 MPa. Vibration data indicate that the fundamental frequency of the structure is low and that it has comparatively flexible bending stiffness. When the wind speed exceeds 15 m/s, the Ferris wheel must be stopped from further operation because the comfort level exceeds the reach of human beings. The measurement results demonstrate that the proposed monitoring system is capable of automatic and real-time monitoring.
