The unit step function and piecewise continuous functions The Heaviside unit step function u(t) is given by u(t) = { 0 if t < 0, 1 if t > 0. The function u(t) is not defined at t = 0. Often we will not worry about the value of a function at a point where it is ...
system dynamics. This approach is used in both continuous and discrete-time spaces that lead to continuous or discrete dynamical systems. In the two cases, a state-space approach uses three vector spaces, n-dimensional state space denoted

The standard application of these techniques usually leads to smooth models that represent a continuous variation of conductivity with depth. In this work, the authors describe how these methods can be modified to incorporate what is known in computer vision as the line process (LP) decoupling ...

The loss-function is assumed to bepiecewise linear, but the slope is allowed to vary in the two directions. springer A simple specification for f(z) is to let it be apiecewise linear, continuous function or a linear spline MultiUn
Lower level sets of continuous selections of C 2-functions defined on a smooth manifold in the vicinity of a nondegenerate critical point in the sense of [11] are studied. It is shown that the lower level set is homotopy equivalent to the join of the lower level sets of the smooth and...
The velocity field is formed by a continuous piecewise affine function defined over 5 intervals. The parametersthetarepresent a basis of the null space for all continuous piecewise affine functions composed of 5 intervals. In this case, we have used the QR decomposition to build the basis. See ...
we prove that a BPUC function has a compact hullfor the-topology and induces a continuous skew-product flow on; and these properties are required in the proof of the mentioned equivalence. For reasons which will become clear in the next paragraphs, we need to deal with bounded piecewise cons...
