diamond wire machining are then introduced. The process monitoring and signal processing techniques for measuring the cutting forces‚ wire speed‚ down feed rate‚ and wire bow angle in diamond wire saw machining are developed. The application of a capacitance sensor to measure the wire bow and a procedure to convert the wire bow to vertical cutting force in a rocking motion wire saw machine are developed. The tension force of the wire during cutting is also derived and discussed. Keywords: Diamond

Digital Storage Oscilloscope * Fluke Digital Multi-meter * Leader LFG 1300S Functional Generator III. Procedure: The engineering team built the circuit shown in figure 1. Keep in mind; use the minimal amount of wiring to avoid stray capacitance which generally happens at high frequency. We used a LN-741 with two dc power supplies and one ac power supply. The dc power supplies consisted of a positive power supply and a negative power supply set at 12V. Once the circuit were built the positive

Homework 2_1 ECET310 NOISE 1. Assume that a receiver has a first amplifier stage with a 5K input resistance‚ a gain of 300‚ an input audio signal of 20 V‚ and an operating temperature of 27oC. When the amplifier is operating with a bandwidth first of 10 MHz‚ find (a) the rms input noise levels (b) the audio output levels (c) the rms output noise levels PN = noise power in watts Tk = 27°C + 273 = 300°K a) Noise level Pn(in) = KT(k)BW = (1.38x10-23)(300°K)(10MHz) = 41.4 x 10^-15 W

Plethysmography is used to measure changes in volume in different parts of the body. This can help check blood. The test may be done to check for blood clots in the arms and legs‚ or to measure how much air you can hold in your lungs. Lung plethysmography: You will breathe or pant against a mouthpiece. Clips will be put on your nose to shut off your nostrils. Depending on the information your doctor is looking for‚ the mouthpiece may be open at first‚ and then closed. You will be breathing

threat to the power bipolar transistor. However‚ initial claims of infinite current gain for the power MOSFETs were diluted by the need to design the gate drive circuit capable of supplying the charging and discharging current of the device input capacitance. This is especially true in high frequency circuits where the power MOSFET is particularly valuable due to its inherently high switching speed. On the other hand‚ MOSFETs have a higher on state resistance per unit area and consequently higher on
