Linear Systems in the Frequency Domain John Semmlow, in Signals and Systems for Bioengineers (Second Edition), 2012 5.1.4 Systems Analysis and Systems Models Systems models usually represent processes using so-called black box components. Each element of a systems model consists only of a mathemat...
a differential equation of the first order of the form dy/dx+Py=Qyα wherePandQare predetermined continuous functions ofxand α is a constant. With the introduction of the new function z = y-α+1, the Bernoulli equation is reduced to a linear differential equation with respect toz.The Bern...
Determine the static equilibrium position of the system. b. Derive the linearized equation of motion for small displacements (x) about the static equi- librium position. c. Find the natural frequency of vibration of the system for small displacement...
Under this assumption, it is possible to conclude that the electromagnetic field quantities in Maxwell's equations are harmonically oscillating functions with a single frequency. Another simplification deals with the fact that for the great majority of induction-hardening applications the velocity of ...
The frequency f is the inverse of the period, or in other words, the number of cycles completed per second (or unit of time, t). For the pendulum on a clock, it completes half a cycle per second, and so it has f = 0.5 Hz, where 1 hertz (Hz) mea...
For example, you see the analysis in a minimal surface equation, but then you also realize it has connections with other geometric questions that are not just analysis. I am definitely very attracted to the idea that there are a lot of different facets in mathematics and seeing the ...

Bagley and Torvik [23], have investigated the movement of a submerged plate that has been bound in a Newtonian fluid and a gas in a fluid, respectively, and established one of the earliest problems of this sort. The frequency-dependent damping materials have been effectively modelled using frac...
