pic16f877a code for heart rate measurement

Heart rate is a very vital health parameter that is directly related to the soundness of the human cardiovascular system. This project describes a technique of measuring the heart rate through a fingertip using a PIC microcontroller. While the heart is beating, it is actually pumping blood throughout the body, and that makes the blood volume inside the finger artery to change too. This fluctuation of blood can be detected through an optical sensing mechanism placed around the fingertip. The signal can ....etc

This article is about a simple heart rate monitor using 8051 microcontroller. Like the previous 8051 projects, AT89S51 is the microcontroller used here. The device senses the heart rate from the finger tip using IR reflection method and displays it on a three digit seven segment display in beats per minute. The circuit has an accuracy of 4 beats per minute and it is very easy to use. In medical terms, the technique used here for sensing heart rate is called photoplethysmography.

Introduction

This study is motivated by a real problem at the Alang ship-dismantling facility near Bhavnagar in Gujarat. The focus of this study is the paint chip waste which is generated in ship breaking activity. Alang, located 56 Km away from Bhavnagar city in Gujarat, came up as ship breaking site during 1982-83. Hundreds of old ships, after their useful life, are broken at the Alang ship breaking yards without any precaution to protect the environment. Ship breaking and its harmful consequ ....etc

matlab code to find false acceptance rate

Abstract

The false acceptance rate, or FAR, is the measure of the likelihood that the biometric security system will incorrectly accept an access attempt by an unauthorized user. A system's FAR typically is stated as the ratio of the number of false acceptances divided by the number of identification attempts. (Webopedia)The false rejection rate, or FRR, is the measure of the likelihood that the biometric security system will incorrectly reject an access attempt by an authorized user. A system's FRR t ....etc
