Classification of cow’s behaviors based on 3-DoF accelerations from cow’s movements

Cow’s behavior classification helps people to monitor cow activities, thus the health and physiological periods of cows can be well tracked. To classify the behavior of cows, the data from the 3-axis acceleration sensor mounted on their neck is often used. Data acquisition and preprocessing of sensor data is required in this device. We acquire data from the 3-axis acceleration sensor mounted on the cows’neck and send to the microcontrollter. At the microcontroller, a proposed decision tree is applied in real-time manner to classify four important activities of the cows (standing, lying, feeding, and walking). Finally, the results can be sent to the server through the wireless transmission module. The test results confirm the reliability of the proposed device

Motorsafe: An Android Application for Motorcyclists Using Decision Tree Algorithm

In Vietnam, prohibitions on using the telephone while driving vehicles have effected in a long time. However, that is relatively common and dangerous for traffic participants in reality. Along with the continuous growing of smartphones, using phone while driving is becoming a bad habit and one of the major causes of crashes and accidents of traffic in Vietnam. MotorSafe is a novel application that has been practically implemented as a solution for this problem. From the obtained data of the accelerometer sensor on the smartphone, a proposed decision tree algorithm enables device to recognize the user's  status on driving a vehicle. Some necessary tasks are provided that will help drivers focus on driving instead of unnecessary behaviors
