The main contents of this paper is the causal set hypothesis, describing spacetime as a discrete, locally finite, partially ordered set aiming on the mathematical description via graph theory. The model of spacetime as a graph is introduced and the principle properties are discussed (causality, particles as parts of graphs, vertexes are the discrete ...

AbstractTree‐based methods are frequently used in studies with censored survival time. Their structure and ease of interpretability make them useful to identify prognostic factors and to predict conditional survival probabilities given an individual's covariates.

Discrete-Time Ordering Policies
IEEE Transactions on Reliability, 1979Optimum ordering policies are discussed for units with discrete failure-time distributions. The results can include a negative ordering time. Under certain conditions, there exists a finite and unique optimum policy minimizing the s-expected cost rate.

To realize a discrete-time filter with either computer software, a programmable DSP chip, or custom VLSI, a network must be specified describing the computations to be performed. For software realizations, the network corresponds to a flowchart of the filter algorithm, while for hardware realizations, the network describes the actual circuit elements ...

Periodic Discrete and Discrete-Time Splines
2018Periodic discrete splines with different periods and spans are introduced in Sect. 3.4 of Volume I (Averbuch, Neittaanmaki and Zheludev, Spline and Spline Wavelet Methods with Applications to Signal and Image Processing, Springer, Berlin, 2014) [2]. In this chapter, we regard periodic discrete splines as a base for the design of periodic discrete-time ...

A martingale is a particular sequence of dependent random variables. The concept comes from gambling systems but is also of great interest in Probability and Statistics.

Continuous and Discrete Time Models
1987Most economists recognize that the use of discrete time is only an approximation, but assume (usually implicitly) that the error of approximation involved is trivially small relative to the other sorts of simplification and approximation inherent in economic theorizing.
