Definable Smoothing of Continuous Functions
Let R be an o-minimal expansion of a real closed field. Given definable continuous functions f : U → R and : U → (0,+∞), where U is an open subset of Rn, we construct a definable Cm-function g : U → R with |g(x)− f(x)| < (x) for all x ∈ U . Moreover, we show that if f is uniformly continuous, then g can also chosen to be uniformly continuous.
متن کاملCombinatorial Continuous Maximal Flows
Maximum flow (and minimum cut) algorithms have had a strong impact on computer vision. In particular, graph cuts algorithms provide a mechanism for the discrete optimization of an energy functional which has been used in a variety of applications such as image segmentation, stereo, image stitching and texture synthesis. Algorithms based on the classical formulation of maxflow defined on a graph...
متن کاملDissipative Continuous Euler Flows
We show the existence of continuous periodic solutions of the 3D incompressible Euler equations which dissipate the total kinetic energy.
متن کاملOn continuous network flows
This work addresses two problems concerning continuous dynamic flows. A model is presented for a network that incorporates continuous time-varying flows, link capacities, node storage capacities, as well as time dependent link delays. It is an enhancement of previous results which do not incorporate time varying link delays. We present a generalized min-cut max-flow theorem for that model. A se...
متن کاملPhase smoothing functions for continuous phase modulation
| In this paper, the problem of signal design for continuous phase modulation is examined. Using the performance measures of e ective bandwidth and minimum distance, \optimal" signal shapes are calculated for various receiver observation intervals for full and partial response signalling. For the partial response case, the optimization could only be done for a receiver observation interval of o...
