kinds of trackers usually consist of a standard desktop computer with an infrared camera mounted beneath (or next to) a display monitor‚ with an image processing software to locate and identify the features of the eye used for tracking . The light enters the retina and a large proportion of it is reflected back‚ making the pupil appear as a bright‚ well defined disc. The corneal reflection is also generated by the infrared light‚ appearing as a small‚ but sharp . Image processing software can identify

Experimental Part 1: Reaction First the glassware apparatus for the reaction was set up. 3.861-grams of isoborneol‚ 2.21-mL of glacial acetic acid‚ and 4.39-mL of 6% NaOCl solution were mixed in a 125-mL Erlenmeyer flask. Another 35-mL of 6% NaOCl solution was added to a separatory funnel and supported over the flask. The NaOCl in the sep funnel was slowly added into the Erlenmeyer flask with vigorous swirling‚ approximately 2-mL every 30 seconds until all the NaOCl from the sep funnel had been

and severity? Many modern scientists attribute these dangerous environmental trends of global warming to the ‘greenhouse effect’. The ‘greenhouse effect’ results from greenhouse gases such as carbon dioxide rising into the atmosphere‚ trapping infrared radiation from the sun‚ and emitting ultraviolet radiation that can puncture the earth’s stratospheric ozone layer. A healthy ozone layer should prevent this from happening‚ but the ozone layer has deteriorated quite considerably due to the world’s

Case study A blue paint layer sample was collected from the wall decorations of the mortuary temple of Ramesses III (Medinet Habu. This temple is one of the largest memorial temples in Egypt. It measures 320 m in length (east to west) and about 200 m in width (north to south)‚ built with order of the Pharaoh Ramesses III (c.1184–1151 BC the 20th Dynasty). The micro-XRF spectrometer (SPECTRO‚ COPRA model) used to analyze the sample includes a side-window X-ray tube with Mo anode (Oxford Instruments

and while some solar radiation is reflected back to space‚ most of the radiation is absorbed by the Earth. As the Earth is warmed‚ heat in the form of infrared radiation is radiated back into the space. However‚ much of this does not escape from the atmosphere but remains trapped by the greenhouse gases‚ warming the atmosphere and cause the infrared rays to be radiated back towards the surface of the Earth. The causes of greenhouse effect include deforestation. Our population is increasing

Since their discovery‚ the nature of quasars has been one of the most intriguing and baffling problems as evidenced by the following quotations: " the problem of understanding quasi-stellar objects is one of the most important and fascinating tasks in all physics" - G.Burbidge and Hoyle. "The quasar continues to rank both as one of the most baffling objects in the universe and one most capable of inspiring heated argument" - Morrison. "The redshift problem is one of the

The physical properties were noted by the reaserchers by the means of their physical state‚color and odor.Using the following reagents: H2o‚ 5% NaOH solution and 5% HCl solution. Solubility and miscibility were tested. Acidity and Basicity of the compounds were determined by the use of litmus paper. Ignition test was conducted using 3 to 5 drops of the sample in a small evaporating dish and light with a match. Lastly‚ the infrared spectrum was use to classify

ABSTRACT The field of human computer interaction has been undergoing a new renaissance lately. While many companies have‚ and continue to spend millions to develop highly visually appealing GUIs and state-of-art interaction systems for the common users since the inception of desktops‚ the development of interactive systems for the disabled has taken a kick start relatively recently. And the Eye gaze systems are one of the most pivotal inventions in this context. The Eye gaze System is a communication
