In this paper, we present a new scheme for the secured transmission of discrete information based on hyperchaotic discrete dynamics. The system is a modified-Henon hyperchaotic discrete-time oscillator considered as transmitter and a delayed step-by-step observer used as receiver. The transmitter parameters play the role of secret keys of the transmission scheme. To increase the robustness of the secure data transmission against known plain-text attacks, the message to be sent is encrypted by additional secret keys and inserted by inclusion method in the chaotic discrete-time system dynamics. By this way, the parameters used as secret keys cannot be identified with usual techniques. Simulation results are presented to highlight the performances of the proposed method. One of the main contributions of this paper is to demonstrate the feasibility of discrete realization of a chaotic observer-based secured transmission scheme. Indeed, experimental implementation results using arduino uno board validate the proposed approach, since it exhibits good performances of throughput and cost in terms of resources used.

Electrical energy plays an important role in today's world, so there is a need to save electricity in addition to its generation using several sources. The proposed intelligent street light system incorporates light-dependent sensors and ultrasonic sensors to intelligently control street lights based on environmental conditions. The system aims to enhance energy efficiency, reduce operational costs and improve safety for pedestrians and motorists. It will use a distributed sensing network with interconnected smart sensors, allowing real-time data exchange and analysis. A central control unit will process the sensor data and activate/deactivate street lights accordingly. The system's benefits include energy conservation, cost reduction, improved safety and scalability. However, successful implementation requires a robust communication infrastructure, accurate and reliable sensors, an adaptive control algorithm, cost considerations, privacy and security measures.

The present work represents the use of thermal based IR sensor camera with arduino technology. Temperatures generated due to micro contacts during dry sliding wear conditions in different conditions are of higher importance in analyzing the surface failure. The adhesive strength, specific wear rate and temperature field analysis on the surface of the nano composite coating are studied for two different coating thickness samples. The nano α-Al₂O₃ particles of 40 nm size are used as secondary phase particles in the Ni matrix coating. The scratch test was carried out to study the adhesive strength of the coating and pin-on-disc for wear studies. An integrated circuit with AMG8833 sensor with arduino uno board is used for the measurement of the temperature and heat map on the surface. The coating is carried out by electro co-deposition technique. The microstructure and composition analysis are carried out by scanning electron microscopy and energy dispersive X-ray analysis. The results show the uniform distribution of the coating particles on the Al6061 substrate with good adhesive strength for the both the coatings. The specific wear results indicate resistance improved by 43.16 % for the 226.32 μm coating. The highest temperature of the debris was found to be 72.6 °C. © 2025 The Authors

Variable-step incremental conductance (***.) technique, for photovoltaic (PV) maximum power point tracking, has merits of good tracking accuracy and fast convergence speed. Yet, it lacks simplicity in its implementation due to the mathematical division computations involved in its algorithm structure. Furthermore, the conventional variable step-size, based on the division of the PV module power change by the PV voltage change, encounters steady-state power oscillations and dynamic problems especially under sudden environmental changes. In this study, an enhancement is introduced to ***. algorithm in order to entirely eliminate the division calculations involved in its structure. Hence, algorithm implementation complexity is minimised enabling the utilisation of low-cost microcontrollers to cut down system cost. Moreover, the required real processing time is reduced, thus sampling rate can be improved to fasten system response during sudden changes. Regarding the applied step-size, a modified variable-step size, which depends solely on PV power, is proposed. The latter achieves enhanced transient performance with minimal steady-state power oscillations around the MPP even under partial shading. For proposed technique's validation, simulation work is carried out and an experimental set up is implemented in which arduino uno board, based on low-cost Atmega328 microcontroller, is employed.

Implementation of a low-cost current perturbation-based improved PO MPPT approach using arduino board for photovoltaic systems

e-Prime - Advances in Electrical Engineering, Electronics and Energy 2024年 10卷

In photovoltaic (PV) systems, the conversion of solar energy into electrical energy by the PV module is influenced by various factors, including sunlight intensity and temperature. To achieve optimal performance, it is crucial to accurately track the maximum power point (MPP) of the PV module. Among the numerous MPP tracking (MPPT) techniques that have been developed, the perturbation and observation (PO) method has gained significant attention due to its simplicity and reliability. However, the fixed perturbation step size used in the traditional PO algorithm can result in poor tracking capability, excessive ripple, and drift, leading to high power loss and low tracking efficiency. To address these limitations, this paper proposes an improved version of the PO strategy that introduces an adaptable step-magnitude mechanism, utilizing current perturbation instead of the voltage perturbation typically employed in the classical PO method. This enhanced indirect PO approach maintains low complexity and can be easily implemented on a cost-effective arduino uno board. A streamlined C++ code integrates the improved PO MPPT strategy with a Proportional Integral Derivative (PID) controller, eliminating the need for separate PID blocks and further reducing system complexity. To evaluate the effectiveness of the proposed technique, comparative analyses are conducted against the traditional PO algorithm, particle swarm optimization (PSO), fuzzy logic control (FLC), and a recently introduced approach, the zone voltage (ZV) method. Simulation results using Proteus software demonstrate that the improved PO approach outperforms the other techniques in various aspects, including achieving the highest static and dynamic tracking efficiencies of 99.38% and 99.88%, respectively, negligible power loss and fluctuations, the fastest convergence speed, and the shortest tracking time of 0.19 seconds. © 2024 The Author(s)

Now a days, traffic congestion is the biggest problem facing city municipalities. There are larger portion of budget which are prepared to solve out this problem each and every year. There are many kind technologies which are introduced but still we are unable to finish such kind of problem. Smart traffic control approach can be a way to minimize this problem. In this system, we are going to use arduino uno board as comparator and weighting machines as input devices for comparison purpose. In this system we are going to check the traffic congestion of road by mean of weighting of the road. This system is going to be very useful for the remote areas where the traffic on any particular road is higher and on other one it is almost equal to zero. This would be easy in implementation and reliable in working.
