Gadget Caretaker for Disabled People

In today’s world population increases promptly. There is a need for a health care center to be developed and well maintained. The purpose is to change the conventional way of patient and nurse communication. We have developed patient independent communication with doctor and nurse by tilting the device located at the hand. In this proposed methodology, the system consists of a sender and receiver part. In the sender part, a two-axis measuring instrument (accelerometer) will be placed on the hand or the finger of the patient. In the receiver section, the LCD is displaying the content. Wherein no one is present to take care the patient so by sending an SMS through GSM module. Our project provides a dependable, effectual and simplex yet essential method of various issues faced by nurses in traditionally communicating with disabled patients

A novel fractional-order dead-time compensating controller for the wireless networks

Abstract Wireless technology is becoming increasingly critical in industrial environments in recent years, and the popular wireless standards are WirelessHART, ZigBee, WLAN and ISA100.11a, commonly used in closed-loop systems. However, wireless networks in closed-loop control experience packet loss or drops, system delay and data threats, leading to process instability and catastrophic system failure. To prevent such issues, it is necessary to implement dead-time compensation control. Traditional techniques like model predictive and predictive PI controllers are frequently employed. However, these methods’ performance is sluggish in wireless networks, with processes having long dead times and set-point variations, potentially affecting network and process performance. Therefore, this paper proposes a fractional calculus-based predictive PI compensator for wired and wireless networks in the process control industries. The proposed technique has been simulated and evaluated on industrial process models, including pressure, flow, and temperature, where measurement and control are carried out wirelessly. The wireless network’s performance has been evaluated based on packet loss, reduced throughput, and increased system latency. The proposed compensator outperformed traditional methods, demonstrating superior set-point tracking, disturbance rejection, and delay compensation characteristics in the performance evaluations of the first, second, and third-order systems. Overall, the findings indicate that the proposed compensator enhances wireless networks’ performance in the process control industry and improves system stability and reliability by reducing almost half of the overshoot and settling an average of 8.3927% faster than the conventional techniques in most of the systems

Smart-Solar Irrigation System (SMIS) for Sustainable Agriculture

This study seeks to develop an automated solar-powered irrigation system. This will provide a cost-effective solution to the traditional irrigation method. This project is aimed at designing a system that harnesses solar energy for smart irrigation and allows for more efficient way to conserve water on the farmland. The system developed is portable and is designed to be adaptable to existing water system. The system incorporates wireless communication technology established using NRF module. For easy operations, the system can be controlled via an Android app-enabled with Bluetooth network. The user experience allows selection of either manual control for scheduled irrigation or automatic control using wireless sensors
