As the United Nations stresses towards clean energy, via its sustainable development goals (goal number 7), animate prime movers are yet another renewable energy resource, which may contribute towards the betterment of humanity. Though considered out-of-place in the modern and futuristic human society, their appropriate utilization, while ensuring welfare elements, can still provide benefits to mankind. In fact, various modern pieces of research mention animal based work in different areas. The current article discusses two concept schemes for renewable/sustainable power generation via animals – issues with prior art have been discussed to bring out the effectiveness of the presented schemes. Furthermore, a simulation based study has been presented in this article, which is another contribution, because studies of animal based power generation, generally do not include simulation work. Lastly, a methodology for training an expert system to detect the fatigue of a power generating animal, has also been briefly discussed in this manuscript. © 2024 IEEE.

In this study, an innovative automated navigation system for delivery vehicles was developed, leveraging real-time object detection technology. This system utilizes a bird's-eye view from high-angle cameras at traffic intersections, with the view segmented into a $7\times 7$ grid, each grid measuring 0.5 meters. The cutting-edge YOLO (You Only Look Once) V8 algorithm is employed for precise vehicle detection in designated areas, adeptly handling various lighting and weather conditions. A key feature of this system is the use of the DeepSORT algorithm for vehicle tracking. DeepSORT excels in maintaining a consistent identification (ID) of each vehicle, crucial in complex scenarios like vehicle obscuration or close proximity of multiple vehicles. This capability ensures continuous and reliable monitoring of each vehicle's route, particularly vital in heavy traffic situations. For autonomous delivery vehicles, the system integrates real-time data from onboard sensors, ensuring accurate vehicle positioning. This integration allows for precise alignment with the vehicle's actual position. Moreover, the system employs Artificial Neural Networks (ANN) trained on diverse vehicle movement patterns. This training, based on comprehensive real-world vehicle movement data analysis, enables the system to accurately predict future vehicle locations. The system's efficacy is underscored by its high predictive accuracy, as indicated by an impressive determination coefficient (R2) of 0.99. In conclusion, this advanced system integrates object detection, effective tracking, and trajectory prediction capabilities in real-time, offering a robust solution for enhancing the safety and efficiency of transport vehicles in high-traffic areas. © 2024 IEEE.

Proposed article deals with implementation of quaternion neural network in application of maximum power point tracking controller (MPPT) for photovoltaic panel. The research compared ordinary 2-layer feedforward neural network with quaternion neural network. The quaternionic model confirmed promising computational potential in terms of final mean square error, 84% reduction of trainable parameters and 57% reduction of multiplication operations. Reduced computational complexity of quaternion neural network-based MPPT controller makes it possible to increase the switching frequency of DC-DC converters, and therefore to use smaller and cheaper electrical components. © 2024 IEEE.

This research aimed to design a sea pimp-shaped monopole antenna by using etching and cutting techniques, combined with the addition of reflector, to modify the antenna structure to support the bandwidth standard according to GSM-850 (0.82–0.90 GHz), GSM900 (0.88–0.96 GHz), DCS (1.72–1.88 GHz), PCS (1.85–1.99 GHz), UMTS (1.92–2.17 GHz), 5G Band40 (2.30–2.40 GHz), LTE41 (2.496–2.690 GHz), and WLAN IEEE 802.11b/g/n (2.4–2.48 GHz). This antenna used a galvanized metal sheet with a conductivity of 3.56 × 107 s/m to fabricate the structure of the radiator, ground plane, and reflector. The reflector modifies radiation patterns and increases the gain of the antenna. The antenna structure used the CST program for simulation to determine the optimal parameters and property values. As a result of replication, the antenna had dual bands with a reflection coefficient (S11) at 915 MHz (736–1040 MHz) of −26.70 dB and a frequency at 2.28 GHz (1.68–2.94 GHz) of −20.15 dB. The antenna gains are 6.70 and 8.47 dBi, an increase of 83.56% and 44.04% over the antenna without a reflector, respectively. The antenna had a unidirectional pattern in all the frequency ranges which can be utilized for the purpose of RF energy-harvesting (RF-EH) systems to provide power to low-power electronic systems. © 2024, Electromagnetics Academy.

Structures fabricated by depositing NiTi thin films onto a flexible substrate like Kapton polyimide can be utilized in micro-electro-mechanical systems (MEMS) such as actuators. However, the development of customized actuators with different fabrication processes can alter the characteristics of thin film and actuation. Micromachining of the bimorph structure using laser energy results in accurate shape generation and can anneal the deposited film due to the absorption of laser heat into the bimorph. In this work, the NiTi Kapton polyimide bimorph actuator was fabricated out of the bimorph sheet using laser-assisted micromachining. The micromachining was performed by a 1064 nm fiber laser at optimized parameters of 5 W laser power, 5 mm/s laser speed, and 50 μm laser spot diameter. The actuators were customized into shapes of triangles of 10 mm side. The interaction of the laser with the bimorph structure has resulted in the grain refinement of the deposited NiTi film revealed by the SEM analysis. The variation in phase transformation temperature was also studied with differential scanning calorimetry. The electrical actuation results of the actuators displayed an improvement of 54% for the laser micromachined actuator. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

In this paper, a novel trajectory generation algorithm for a rectangular hexapod robot in a complex environment based on a genetic algorithm (GA) when the robot is moving in a tripod gait. The main objective is to find the shortest trajectory between the initial and target locations while considering the hexapod's physical constraints, such as the maximum step length, as well as collision avoidance with surrounding obstacles. Since rectangular hexapod robots perform better in forward and side motion compared to angular motion, it is preferable to move either horizontally or vertically. Therefore, finding the desired direction of motion (horizontal or vertical) is also considered during the trajectory planning procedure. First, a kinematic model of the hexapod is presented. Then, the planned trajectory is divided into a number of segments. Subsequently, GA is applied to find the optimum design variables that yield the shortest and collision-free trajectory. These variables include the number of steps, the length of each step, and the corresponding direction of motion (horizontal or vertical) during each segment. Finally, different simulation scenarios are conducted to demonstrate the effectiveness, convergence, and stability of the proposed algorithm. © 2023 IEEE.

The coal mine hoisting system is responsible for the lifting and lowering tasks of underground workers, coal and equipment. As an important part of the hoisting system, the safety performance of rigid guide rail directly affects the safety of coal mine production. In order to solve the problem of low efficiency of manual inspection at present, this paper proposes a new rigid guide rail fault detection robot and detection method. First of all, based on our previous research, a new detection robot prototype is developed. Secondly, a method of detecting rail fault using robot attitude is proposed. Finally, the performance of the robot and the effectiveness of the detection method are verified by field experiments. At present, the robot proposed in this paper is the first robot tested onsite for fault detection of rigid guide rail of coal mine hoisting system. The detection robot system proposed in this paper can improve the intelligent and unmanned level of coal mines, and can also be extended to the detection of railway tracks and elevator guide rails in buildings. © 2023 IEEE.

In large tiled chip multiprocessors (TCMP), the connectivity between different processors is through Network on Chip (NoC). In NoC, NoC router plays a very important role. The two different types of routers are Buffered and Bufferless NoC routers. A bufferless NoC router is a viable solution due to its modest router architecture, hardware effectiveness and energy. Because several subnetworks are linked by an additional link amid two related routers, DeC allows a challenging flit in one subnetwork to be transmitted to other subnetwork rather than being deflected. NoC is defined by performance metrics such as latency, deflection rate, throughput, and power, all of which are dependent on the underlying network architecture. In this paper, a novel method such as Deflection Containment Path Distance Analyzer (DeC-PDA) Bufferless NoC router is proposed to solve the problem of extreme deflection during flit transmission. The results show that the area consumption is less compared to buffered routers. © 2024 IEEE.
