processes of applying this coating‚ i.e. Dip coating and Spin coating. The current scratch resistant (Hard) coating on plastic and polycarbonate lenses available in the industry has a scratch resistant property of 4H as per Pencil hardness test. Titan Lens lab has tried improving the hardness of the coating in the past but was able to achieve greater hardness up to 6H‚ but as soon as we apply Antireflection coating on this surface‚ the hardness again drops to 4H. Due to this‚ the lenses get scratched over

1. How do you calibrate an Oscilloscope? In order to calibrate the Oscilloscope‚ we connected the BNC alligator into the channel we wanted to calibrate (Channel 1). We clipped the red probe to the calibration knob‚ and we saw a 2 volt VPP signal. The desired output from the oscilloscope was a 1000 Hz calibration frequency. The 1000 Hz frequency is the standard frequency for most of the oscilloscopes. After we clipped the red probe‚ we saw a square wave signal. The first thing we calibrated was the

Points are scored when a player fails to return the ball within the rules. Play is fast and demands quick reactions. Spinning the ball alters its trajectory

CHAPTER 4 Objectives: 1. Define consciousness.--------- 2. Appreciate the role of the circadian rhythm. 3. Describe the stages (5) of sleep including the sequence of the stages. The development of the electroencephalograph led to dramatic increases in what is known about sleep. When electrodes are attached to the face and scalp of sleepers‚ different patterns are produced on the graphic record called the electroencephalogram or EEG. The patterns vary in frequency and amplitude of the waves
