262. Analysis of vibrations of paper in a printing device

email: [email protected] (Received 1 March 2007 accepted 23 March 2007) Abstract. The model for the analysis of vibrations of paper in a printing device is presented. It is assumed that paper performs transverse vibrations as a membrane having stiffness due to static tension in its plane. The first eigenmodes are determined.

What is microphone? Definition from WhatIs

microphone: A microphone is a device that translates sound vibrations in the air into electronic signals or scribes them to a recording medium. Microphones enable many types of audio recording devices for purposes including communiions of many kinds, as well as music and speech recording.

Fourier transform theory homepages.inf.ed.ac.uk

Now, a step function (or a square wave form) can be represented as a sum of sine waves of frequency, where is the frequency of the square wave, and we recall that frequency = 1/wavelength. Normally, frequency refers to the rate of repetitions per unit time, that is, the number of cycles per second (Hertz).

Differential Equations Periodic Functions & Orthogonal

In this section we will define periodic functions, orthogonal functions and mutually orthogonal functions. We will also work a couple of examples showing intervals on which cos( n pi x / L) and sin( n pi x / L) are mutually orthogonal. The results of these examples will be very useful for the rest of this chapter and most of the next chapter.

Stepwise simulation of vacuum transfer line hydraulics

Therefore, many transfer lines, designed to run under sonic velocity, actually operate at critical velocity, especially near the heater outlet and at the column entrance. The potential impacts of critical velocity are not trivial. The vibration of shock waves could result in failure of the vacuum transfer line.
