Nettet1. mai 2000 · A summary of turbulence modulation effects up to 1989 was published by Gore and Crowe. These data included both jets, flow in pipes, gas-particle and gas–liquid flows. The data showed a general trend; small particles tend to attenuate turbulence, large particles tend to enhance turbulence. NettetIntensity modulated proton therapy (IMPT) implies the electromagnetic spatial control of well-circumscribed "pencil beams" of protons of variable energy and intensity. Proton pencil beams take advantage of the charged-particle Bragg peak-the characteristic peak of dose at the end of range-combined w … dra samira hematologista

NettetLinear Intensity Modulator: slection of optimum carrier power is essential to minimize distortion.Limiting depth of modulation also ensures distortion free transmission. (a) Select an IF (dc) =10mA (corresponding to carrier power Po of -14dbm to 17 dbm) as dc operating point. NettetWorking of CRO In the past, CRO consists mainly of a vacuum tube that contains a cathode, anode, grid, X & Y -plates, and a fluorescent screen. When the cathode is heated (by applying a small potential difference across its terminals), it emits electrons. NettetMach–Zehnder interferometers are used in electro-optic modulators, electronic devices used in various fiber-optic communication applications. Mach–Zehnder modulators are incorporated in monolithic integrated circuits and offer well-behaved, high-bandwidth electro-optic amplitude and phase responses over a multiple-gigahertz frequency range. dr asad cheema nj
