The study of chaotic systems with special properties addresses one of the ongoing research topics. In this paper, we introduce a new class of third-order chaotic systems possessing a cyclic symmetry obeying unidirectional or mutual coupling. These new models are built by considering nonlinearities with three, four, or five segments and are distinguished from each other by the topological structure of the associated chaotic attractor. The projection of the novel chaotic attractors on certain planes reveals their multiscroll or multiwing character. For illustration, one of these models is studied in detail using analytical and numerical methods. The mechanism giving rise to the establishment of the chaotic regime starting from the state of equilibrium under the variation of a parameter is described using bifurcation diagrams, phase portraits, basins of attraction as well as the maximum Lyapunov exponent. Several zones of parameters are identified where the model experiences two or more attractors (i.e. multistability). In order to demonstrate the practical feasibility of the proposed circulant models, a series of experimental measurements are carried out using a physical implementation with an arduino microcontroller.

Robots are extensively used in industries for their precision work and amount of work that one can obtain without any defects. In this paper we are using a gantry robot for as it does not occupy the floor space therefore reducing the distance for reachability of the parts and hence reducing unnecessary material for guide way. Robots work in strictly defined path and there is no or very little change in such systems in order to overcome this we are using a vision based control system to make the system dynamic in nature the images are picked by using a USB camera processed images of the object is transmitted via serial communication to the arduino Mega 2560 microcontroller and processed using pythons open source computer vision (Open CV) image to process the image captured by the USB camera to find the exact colour and to pick the object and sort it.

The global challenge of environmental air quality monitoring necessitates the development of innovative solutions. In response, a novel intelligent system was designed to monitor air quality through the integrated analysis of gases (carbon dioxide, carbon monoxide, and liquefied petroleum gas), room temperature, and humidity, utilizing the arduino microcontroller and the Internet of Things application. The initial phase involved rigorous component selection, including the arduino microcontroller, gas sensors, Wi-Fi module, humidity and temperature sensors, LCD display, buzzer, and communication with the Blynk application. Subsequently, seamless integration of these electronic components of the system and envelopment of the prototype in acrylic material were accomplished. After envelopment, the system was then deployed for integrated environmental monitoring of gases, temperature, and humidity. The results showed that the developed system exhibits a cost-effective and high-performance solution, characterized by its compactness, practicality, and versatility in various environments. Its implementation costs are significantly low, making it commercially viable.

RSA Cryptography is a well-known example of public key cryptographic algorithms that involves robust encryption/decryption processes. In this paper, a microcontroller based RSA is designed and proposed. arduino Mega2560R3 microcontroller supported with external memory and a screen touch LCD as well as a double keypad has been used under the programming of C language to implement the proposed RSA coprocessor with 32 bits. It was found that the trade of between message size and the encryption time can be drawn as a liner relationship according to the block size of the encryption phase. However, such design with a MCU provided with a small solar cell (and off course with a backup battery) as well as small block sizes is considered useful for the use in wireless sensor network (WSN) applications due to the ease of connecting the MCU to the WSN which as well avoid the processing time of encryption/decryption processes that could be executed by the MCU instead of the life limited sensors.

The development of an automatic headlight beam control system is a significant leap in automotive safety and efficiency. This system aims to automatically regulate headlight beams, addressing issues of driver visibility and nocturnal traffic accidents caused by improperly controlled high beams. Machine learning-based approaches have gained traction in addressing these concerns, but their high-cost limits accessibility, especially in developing nations with prevalent nocturnal driving accidents. To bridge this accessibility gap, our study proposes a cost-effective sensor-based arduino controlled headlight beam luminance intensity control system applicable to a wide range of vehicles. Key features include a beam transition alert and the integration of a radar sensor to detect moving objects triggering a headlight beam switch. Field trials confirm the feasibility of this adapted sensor-based approach, although limitations related to the range of the light-dependent resistor (LDR) sensor are acknowledged. Future research should explore the integration of long-range LDR sensors for enhanced functionality. As technology evolves, we anticipate more sophisticated iterations, promising transformative changes in nighttime driving for the benefit of all road users.

The use of IoT technology is constantly and uninterruptedly increasing. Sensors in the IoT environment collect large amounts of data and send them to servers. The user's data in IoT applications, which has a large volume, is the big data. Big data belonging to IoT network users expose various security attacks and challenges. One of the technologies that provide data security in the Internet of Things is Blockchain technology. In Blockchain technology, all participating nodes participate in this distributed cryptography for data validation. This article aims to provide a blockchain-based distributed software architecture for real-world application software to increase its security. The arduino nightly 1.6.12 software simulates and extracts the raw data and codes the modules. In this method, the extracted data analyze after storage in the database. Only transient security threats are identified and corrected by applying software approaches, but in the proposed framework, which is the hardware approach, persistent errors can also be identified and corrected. From the point of view of implementation cost, the hardware method has 66.7% hardware overhead. This method is practical and highly valued in applications where data security is essential.

IRRIGATION AND DRAINAGE 2023年第1期72卷 259-267页

The wide variation in water demand and pressure means that most irrigated perimeter pumping systems are oversized. The objective of this study was to control a pressurized irrigation system using a frequency inverter, aiming at automation and energy savings in irrigated perimeters. First, a prototype was assembled using drawer valves to simulate head losses in the system. Second, a frequency inverter was used to control the speed of the rotation of the motor pump, improving its performance. Finally, a microcontroller was used to manage the number of plots under irrigation in the perimeter. The frequency inverter reduced the consumed power by 40, 30 and 19% and the electric power consumption per hour by 46, 38 and 23% for one, two and three plots under irrigation, respectively. The use of the inverter frequency led to a reduction in operating points for all irrigation plot scenarios evaluated. The use of the frequency inverter is justified when the full power of the pump is not always required and adjustment of the rotation speed is necessary. In addition, the proposed automation system proved to be efficient in managing the rotation control of the frequency inverter.

The Remote Sensing Laboratory - Andrews (RSLA) initiated an advanced robotic systems feasibility study project under the Site Directed Research and Development (SDRD) in 2023. Two prototype systems with radiation detection sensors were developed and tested for use in the forensics investigation of debris produced from explosively dispersed radioactive materials. To automate the robots, an arduino microcontroller was added, and instead of reading signals directly from the radio control receiver, the system takes signals from the motor controller. The robots can be programmed to drive various search and survey patterns. Mapping results obtained by deploying this robotic system will be presented. The arduino microcontroller system was chosen for this project for its value as a prototyping tool. Specifically, the Mega 2560 R3 model was chosen for its multiple data inputs and low power draw, allowing it to be integrated into the originally designed robotic system without requiring additional power capacity. The arduino system is designed to be easily modified and can serve as a proof of concept for further development with proprietary systems in the future. The system was programmed in C++ using the arduino IDE (Integrated Development Environment). Issues arose during development when attempting to use the software library developed by the manufacturer of the Sabertooth controller, but when that was replaced in favor of a standard motor control library, the robot functioned as intended. The prototypes used to measure a baseline ground truth of a radiation field;these will be compared to low flying Unmanned Aerial Systems (UAS) for optimizing flight profiles.
