The effect of caffeine on typing speed‚ accuracy and heart beat 1. Introduction Caffeine is a substance found in coffee‚ tea and most sodas. When it is consumed‚ it is a mild stimulant. The energy drink‚ Monster‚ contains caffeine‚ which has the ability to manipulate adenosine (adrenaline)‚ a substance present in the brain that is used to transmit brain signals to different parts of the body. Adenosine causes an increase in alertness and awareness. Modern studies show that there is direct benefits

Speed of the Human Neural Impulse Helmholtz (1821-1894) was a German scientist. In 1850‚ he measured the neural impulse in frogs. By strapping down the frogs and putting electrical voltage into their legs‚ Helmholtz measured the time it took for the frogs’ leg to twitch. Helmholtz used a galvanometer to measure the neural impulse. He found that the neural impulse in frogs was 83-90 ft/s. Afterwards‚ Helmholtz went on to test the neural impulse in humans. He put a low grade electrical voltage to humans’

TITLE CONTACTLESS TACHOMETER ABSTRACT: The aim of the project is to design a contactless speed sensing device (tachometer) for a motor. Traditional tachometers require a physical contact to the shaft of the motor to measure the speed. In certain applications‚ where it is not possible to measure the speed directly‚ it is possible for a contactless tachometer to take the readings from a certain distance. This is the main motivation behind choosing this project. This contactless tachometer

Proposal for Automated Speed Radars for North Luzon Expressway I. INTRODUCTION 1.1 Purpose This document purposes an automated method teaching the speed violators at North Luzon Expressway. The automation system is necessary to easily detect those violators who are going beyond the speed limit and to improve the security in NLEX. 1.2 Background The North Luzon Expressway or NLEX runs a total distance of 84 kilometers from Balintawak‚ Quezon City to Sta. Ines‚ Pampanga.

Hyperloop Vs. High-Speed Trains When it comes to high-speed transportation the United States falls short compared to the rest of the world. Currently in California there is a need for a mode of transportation that can get passengers around quickly and at a reasonable cost. The ideal mode of transportation to solve the problem would be either a high-speed train or a Hyperloop system. Given the manufacturability‚ increased efficiency‚ and reduced costs of the Hyperloop it would be the right choice
