IoT-Enabled Multi-Sensor Accident Detection and Automatic Rescue Alert SystemBy Valluri Dhana Raj, S. Maheswari, A. Athyusha, S. Karishma, S. Surya Karthik, D. K. Veerabhadra Rao
Abstract: Road accidents and vehicle instability caused by skidding, engine overheating, and improper braking behavior remain major concerns in modern transportation systems. This project presents an intelligent vehicle safety and accident detection system that integrates multiple sensors and control logic to enhance driving safety and reduce accident severity. A vibration sensor is employed to detect collision or impact events and accurately identify vehicle accidents. An accelerometer sensor is used for real-time …

Koch Slot DRA Antenna Array for Enhanced X-Band ApplicationsBy K. Anantha Lakshmi, Valluri Dhana Raj, Ch. Sridevi
Abstract: This work introduces an innovative method aimed at improving the gain of Dielectric Resonator Antenna (DRA) arrays functioning within the X-band spectrum. The design features a Koch-shaped slot-coupled feeding structure, utilising the properties of a short-ended microstrip line to enhance radiation directionality. The results of the simulation show that compared to conventional rectangular and V-shaped slot designs, the suggested antenna array provides a notable gain enhancement. This performance boost demonstrates …
