Solar irradiation is a green and sustainable renewable energy source which is largely harnessed through photovoltaic and thermal cell surfaces. It is one of the fastest growing clean power technologies with high-global growth figures, due to its simplicity, affordability and abundant availability. Solar power systems is one of the fastest growing interventions augmenting fossil power and its application is now expanding beyond domestic utilization to commercial and industrial dependence. Due to continuous change in the position of the sun together with other salient factors, only a fraction of the suns energy potential is harnessed. The paper is focused on sharing an optimization option that has effectively addressed a major gap experienced in conventional solar power system installation as applicable to light emitting diodes traffic light systems. The continuous movement of the sun limits maximum sun light irradiation absorption and solar trackers are practical solutions to this drawback. The high cost of solar trackers has however been the major limitation to their adoption. The Introduction of microcontroller-based solar tracking systems using arduino board was found to be cost effective, and it improved the efficiency of the solar cells significantly. In the study, the maximum power point tracking algorithm was designed and developed using multiple-axis servo-motor feedback tracking system, which increased the efficiency of the solar panel array by 23.95%.

Energy-saving potential in lighting is significant in office buildings due to their primary occupancy during the daytime. This potential can be realised with an advanced daylighting system being particularly able to deliver more uniform and steadier illumination. This paper presents prototyping and experimental validation of an automated louver with parametrically-angled reflective slats, in order to reflect sunlight to evenly distributed target positions on a ceiling. The illuminated ceiling acts as a source of diffuse light to the room. The physical rotation of the automated louver is controlled parametrically using Grasshopper software together with arduino board, motors for the motion and illuminance sensors. Validation is an essential stage to ensure the performance of such systems. Two prototypes of the proposed system with different scales are presented, 1:20 and 1:1 scaled mock-ups. The monitoring results verify the principle and aim of the proposed design, i.e., more uniform and distributed daylight illumination, automation control method besides its practicality.

We present a low-cost experimental apparatus designed for studying the rotational dynamics of a meter stick. This apparatus uses everyday laboratory supplies, 3D printed parts, and an arduino board for data acquisition. It consists of a common bearing fixed to a vertical axle, connected to the meter stick through a 3D printed spindle adapter. A thread attached to a hanging weight and winded around the spindle applies a constant external torque to the stick. The moment of inertia of the apparatus may be changed by incorporating weights into the apparatus through 3D printed adapters. An arduino board records the time interval between consecutive half turns of the stick, allowing the calculation of the angular displacement over time. The data collected from experiments is compared with theoretical models. Among others, the effect of the applied torque, air resistance and moment of inertia of the stick is studied. This experimental apparatus is particularly suitable for undergraduate students enrolled in a classical mechanics course, offering them a practical, hand-on experience while remaining cost-effective. © 2024 The Author(s).

This article describes a simple setup of electrospinning using widely available resources. The arduino board, an electronic platform that is commonly accessible was adapted for a controller. Specifically, recycled parts consisting of plastic gears and a lipstick case were incorporated for the construction of a syringe pump. A cheap DC-DC converter was utilized to provide a high voltage supply for stretching of a polymer solution. In order to test the performance of the setup, we obtained the electrospinning fibres with cigarette filter tips dissolved in acetone and liquid glue. The analysis results indicated the average diameter of fibres ∼3.7 ± 0.5 µm and ∼2.8 ± 0.3 µm, respectively. The whole process of controlling can be automatically conducted by a simple application written in DELPHI 7.0 language. It could serve as a form of research project to improve students' lab experience. © 2021 IOP Publishing Ltd.

This study investigates the potential of deploying a neural network model on an advanced programmable logic controller (PLC), specifically the Finder Opta (TM), for real-time inference within the predictive maintenance framework. In the context of Industry 4.0, edge computing aims to process data directly on local devices rather than relying on a cloud infrastructure. This approach minimizes latency, enhances data security, and reduces the bandwidth required for data transmission, making it ideal for industrial applications that demand immediate response times. Despite the limited memory and processing power inherent to many edge devices, this proof-of-concept demonstrates the suitability of the Finder Opta (TM) for such applications. Using acoustic data, a convolutional neural network (CNN) is deployed to infer the rotational speed of a mechanical test bench. The findings underscore the potential of the Finder Opta (TM) to support scalable and efficient predictive maintenance solutions, laying the groundwork for future research in real-time anomaly detection. By enabling machine learning capabilities on compact, resource-constrained hardware, this approach promises a cost-effective, adaptable solution for diverse industrial environments.

作者： Shrey Patel Harsh Oza Yash Sharma Tirth Patel Smita Agrawal Parita Oza Institute of Technology Nirma University Ahmedabad India

Waste generation is a challenge for both developed and developing countries. Developing countries face economic and technological constraints in implementing smart city development measures. This study proposes a novel smart waste management solution that is powered by solar energy and can be implemented in developing countries as well as developed countries. The solution presents an IoT-enabled smart trash bin that can be remotely monitored to track its fill levels. This information is used to optimize the collection routes of waste trucks, reducing fuel consumption and emissions. The solar-powered design of the smart trash bins makes them more sustainable and environmentally friendly. The smart trash bins are also equipped with a mechanism to automatically open the lid when waste is detected, providing a contactless, hygienic method of waste collection. Smart dustbins can help to reduce the spread of diseases caused by contact with waste by minimizing human contact with trash bins. Smart waste management systems can lead to a cleaner, healthier environment and improved quality of life for people living in the area. By preventing overflowing bins and providing real-time monitoring of waste levels, smart dustbins can reduce the amount of litter on the streets and in public areas. The real-time monitoring of the trash level can help in optimizing the waste collection process with timely waste collection.

Piezoelectric energy harvesting devices convert mechanical energy into electrical energy due to the mechanical deformations of the structures. Energy harvesting prototypes are used to feed low-power electronic devices and sensors. In this work, a one-dimensional finite element is developed for modeling three-dimensional rotational energy harvesters. The rotating piezoelectric beam is formulated by means of a geometrically nonlinear finite element with six mechanical degrees of freedom and one electrical degree of freedom per node. Using Timoshenko beam theory for the mechanical domain and a first-order theory for the electrical field, the electromechanical equilibrium equations of motion are then derived using D'Alembert principle. In order to validate our finite element formulation, two energy harvesting devices are built and tested, getting insights into the generation of electrical power, natural frequencies and time responses of the dynamical variables. An arduino board is implemented as the data acquisition system that transfers the voltage signal via Bluetooth, avoiding the complexity of slip-rings mechanisms for data transmission. Finally, the results of our formulation are compared with those obtained using a commercial software (Abaqus) and the experimental results. A good correlation between the three methods is obtained, providing evidence that our formulation accurately predicts the behavior of rotational energy harvesters.
