  • Smart Cattle Health Monitoring: A Heat Stress Management System
    Siva Reddy Vanga, Nagarjuna Reddy Thontla, Hari Sai Chandu Bolla
    2025 6th International Conference for Emerging Technology Incet 2025, 2025
    Heat stress in dairy cattle is a significant challenge due to rising temperatures, which negatively impact their health, productivity, and reproduction. To address this, a real-time monitoring system is developed using multiple sensors, including a temperature and humidity sensor, the MLX90614 infrared sensor for measuring surface temperature, and the MAX30102 pulse oximeter to track pulse rate. In addition,a 3D accelerometer is used to analyze cattle movement patterns. The system employs the STM32BL475E-IOT1A microcontroller to process sensor data, determine the Temperature Humidity Index (THI), and classify cattle activity into three categories: idle,walking, and running.By using NanoEdgeAI, the system executes on-device machine learning for real-time activity classification and behavior analysis. The data is indicated on a local screen and transmitted via Wi-Fi to a web-based dashboard, allowing farmers to monitor cattle health and movement remotely.This intelligent monitoring solution optimizes farm management, enhances animal welfare, and precludes productivity losses caused by heat stress and abnormal activity patterns.

  • Sunstroke Detection and Alert System for Farmers
    Siva Reddy Vanga, Thanniru Indhu, Dasari Sai Sundar, Kolluri Sireesha
    2025 12th International Conference on Reliability Infocom Technologies and Optimization Trends and Future Directions Icrito 2025, 2025
    Sunstroke is a serious medical condition, particularly for farmers who work throughout prolonged periods of heat. This project proposes a Sunstroke Alerting and Detection System accompanied by a mobile app that will maintain the farmers in contact with their caretakers. The system uses sensors to monitor the health of the farmer by sensing environmental temperature, humidity, body temperature, heart rate, and SpO2 level to reach pre-sunstroke. When the system reports critical levels of these parameters, Dfmini player module alerts farmer via speaker and GSM module alerts their caretakers. Also, the caretaker receives update from the mobile application on if farmer has seen the notifications or not. The system also provides the farmer's illness, enabling the caretaker to administer treatment if the farmer gets sick because of ignoring the warnings while still working in the fields.
  • Parallel Prefix Adders Based Linear Congruential Generator
    A S Safa, Siva Reddy Vanga
    2024 3rd International Conference on Electrical Electronics Information and Communication Technologies Iceeict 2024, 2024
    In cryptography pseudo-random generators play a key role; to generate these random bits linear congruential generator is implemented with different parallel prefix adders to increase the speed of operation. LCG module consists of a shifter, adder, multiplexer, and register. In parallel prefix adders, the operation is performed in parallel by dividing into smaller pieces that are done in parallel. To further reduce the number of grey cells and black cells Ladner-Fischer adder is implemented for further reduction in the proposed LCG. In the place of the adder is replaced with different adder structures and is verified with different FPGA families for the utilization and timing report. The architecture is implemented using Verilog HDL, simulated, and synthesized using Vivado.
  • Helmet Guard: Engine Management and Accident Severity Assessment for Motorcycles
    Sivarama Krishna Reddy Vanga, Niharika Angadala, Purna Gowtham Alajangi
    2024 15th International Conference on Computing Communication and Networking Technologies Icccnt 2024, 2024
    Motorcycle safety systems traditionally face limitations in engine control, accident assessment, and rider protection. This paper introduces a solution that enhances engine management employs machine learning for accurate accident severity analysis, and incorporates alcohol detection with accelerometer-based tilt assessment designed for motorcycles. This project mandates helmet usage before the engine starts, ensuring the rider’s safety. The system concurrently monitors critical factors such as alcohol concentration and tilt angles and deactivates the engine upon detecting irregularities. This innovative approach helps make riding motorcycles safer and smarter by overcoming previous problems. It represents a significant advancement, promising enhanced security and intelligence on the road.
  • Efficient Cattle Health Monitoring Using a Compact AI Model
    Siva Reddy Vanga, Thontla Nagarjuna Reddy, Chalibindi Venkatesh, Bolla Hari Sai Chandu
    2024 5th IEEE Global Conference for Advancement in Technology Gcat 2024, 2024
    The dairy industry plays a crucial role in the global food supply chain, and with the advent of technology, it is evolving rapidly. This work introduces an AI model for monitoring the health of cattle. Traditional dairy farming methods are often labour intensive and reliant on manual monitoring, which can lead to inefficiencies and reduced profitability. Cattle health monitoring by integrating artificial intelligence (AI) with the STM32BL475IOT1A microcontroller. The key innovation lies in an AI model developed for the STM32BL475IOT1A. It is capable of analyzing sensor inputs to detect and predict various health parameters in cattle like temperature, and pulse rate of the cattle by developing an artificial neural network (ANN) in Python that can predict the health of cattle.
  • Chest CT Image based Lung Disease Classification – A Review

    Current Medical Imaging, 2024
    Computed tomography (CT) scans are widely used to diagnose lung conditions due to their ability to provide a detailed overview of the body's respiratory system. Despite its popularity, visual examination of CT scan images can lead to misinterpretations that impede a timely diagnosis. Utilizing technology to evaluate images for disease detection is also a challenge. As a result, there is a significant demand for more advanced systems that can accurately classify lung diseases from CT scan images. In this work, we provide an extensive analysis of different approaches and their performances that can help young researchers to build more advanced systems. First, we briefly introduce diagnosis and treatment procedures for various lung diseases. Then, a brief description of existing methods used for the classification of lung diseases is presented. Later, an overview of the general procedures for lung disease classification using machine learning (ML) is provided. Furthermore, an overview of recent progress in ML-based classification of lung diseases is provided. Finally, existing challenges in ML techniques are presented. It is concluded that deep learning techniques have revolutionized the early identification of lung disorders. We expect that this work will equip medical professionals with the awareness they require in order to recognize and classify certain medical disorders.
