    product was then distilled using a Hickman still and characterized using infrared spectroscopy. The percent yield of isopentyl acetate was 61.52%. This may have been low due to not all of the condensed product being removed from the Hickman still‚ some product being lost during transfer of the product from the reaction tube into the Hickman still‚ or the loss of some product due to evaporation during distillation. Infrared spectrum analysis of the product indicated that the product was isopentyl

    Electromagnetic Waves It was once the great Scottish physicist James Clerk Maxwell (1831-1879) who had presented that electric and magnetic fields unstable together can form a spreading wave‚ appropriately called an electromagnetic wave. The properties of an electromagnetic wave are as follows: 1. They can travel through a vacuum at the same high speed‚ which is much faster than other types of waves that travel through a material. 2. They show the normal wave properties of reflection‚ refraction

    indicator lamps in many devices and are increasingly used for general lighting. Appearing as practical electronic components in 1962‚ early LEDs emitted low-intensity red light‚ but modern versions are available across the visible‚ ultraviolet‚ and infrared wavelengths‚ with very high brightness.When a light-emitting diode is switched on‚ electrons are able to recombine with holes within the device‚ releasing energy in the form of photons. This effect is called electroluminescence‚ and the color of

    GAIT ANALYSIS AND RECOGNITION TECHNIQUES Gait analysis is the systematic study of animal locomotion‚ more specifically the study of human motion‚ using the eye and the brain of observers‚ augmented by instrumentation for measuring body movements‚ body mechanics‚ and the activity of the muscles. Gait analysis is used to assess‚ plan‚ and treat individuals with conditions affecting their ability to walk. It is also commonly used in sports biomechanics to help athletes run more efficiently and to identify

After calibration the system will read the incoming voltage and correlate that to an angle measurement. Exercise 4: Using the infrared sensor we are able to find how far away some thing is. We took readings at measured intervals and correlated those readings to the measured distances. Results: Exercise 1: This was a quick exercise. Take readings
