A piecewise Markov process is a discrete-state, continuous-parameter stochastic process which is Markovian within contiguous time-segments. Starting at the beginning of a segment in some initial state, the process evolves in a Markovian manner until the segment terminates at a random time whose distribution is completely determined by the initial state.

In this paper a new strong form of directability of automata is studied. A word $w$ is piecewise directing if any input word containing $w$ as a piecewise subword takes the automaton to the same state from every state. The piecewise directable automata form a variety of automata situated between the varieties of definite automata and directable ...

A piecewise approach to piecewise approximation
Numerical Algorithms, 1997Fitting a tensor product spline to a general set of data is the aim of this report. An algorithm given here for the bivariate case is shown (through illustrations) to be effective and the application to a parallel environment is considered.

Piecewise-Constant Stabilization
SIAM Journal on Control and Optimization, 1999In this paper the author addresses the feedback stabilization problem for continuous-time and discrete-time nonlinear control systems. After presenting necessary conditions for the stabilization via smooth feedbacks, the author turns to the main topic, which is the stabilization via piecewise constant feedback laws, i.e. mappings \(u: \mathbb R^n\to U\)

Piecewise fractional Brownian motion
IEEE Transactions on Signal Processing, 2005Starting from fractional Brownian motion (fBm) of unique parameter H, a piecewise fractional Brownian motion (pfBm) of parameters Hi, Ho and gamma is defined. This new process has two spectral regimes: It behaves like an fBm of parameter Ho for low frequencies and like an fBm of parameter Hi for high frequencies .When Ho = Hi, or for limit cases, pfBm ...

On Piecewise Linear Functions and Piecewise Linear Equations
Mathematics of Operations Research, 1980In this paper we treat of the number of solutions of certain piecewise linear (p.l.) equations and of necessary and sufficient conditions for a PL function to be a homeomorphism. The function f: Rn → Rm is PL when a finite set H of hyperplanes exists such that Rn\∪H is the disjoint union of open polyhedral sets C1, …, Cq and F ∣ C̄ (x) = Aix + bi with

Cumulative chords,Piecewise-Quadratics and Piecewise-cubics
2006Cumulative chord piecewise-quadratics and piecewise-cubics are examined in detail, and compared with other low degree interpolants for unparameterized data from regular curves in R n , especially piecewise-4-point quadratics. Orders of approximation are calculated and compared with numerical experiments.

Piecewise Linear Incentive Schemes
The Scandinavian Journal of Economics, 1988The properties of piecewise linear incentive schemes are studied in a setting of moral hazard and adverse selection. The form of the best such function is analyzed. Particular attention is given to the loss from using piecewise linear schemes relative to ``optimal'' schemes, as well as the gain from using simpler functional forms such as the linear ...
