Transformed Lévy processes as state-dependent wear models
Advances in Applied Probability, 2019 Many wear processes used for modeling accumulative deterioration in a reliability context are nonhomogeneous Lévy processes and, hence, have independent increments, which may not be suitable in an application context.

The multifaceted behavior of integrated supOU processes: the infinite variance case [PDF]
, 2020 The so-called "supOU" processes, namely the superpositions of Ornstein-Uhlenbeck type processes are stationary processes for which one can specify separately the marginal distribution and the dependence structure.

Scientia Marina, 2005 Characteristics of temperature-dependent metabolic adaptation as well as their implications for associated changes in energy budgets are analysed based on comparisons of fish and invertebrates from various latitudinal clines in northern and southern ...

Chinese Journal of Aeronautics, 2018 Abstract Nowadays, more and more attentions are paid to electromagnetic incremental forming (EMIF), especially for a part with a large-scale size, e.g., an integral panel with stiffened ribs. In this work, the bending of a panel into a double-curvature profile via EMIF is carried out experimentally and evaluated by comparing the formed profile with ...

Limit theorems for integrated trawl processes with symmetric Lévy bases [PDF]
Electron. J. Probab. 25 (2020), Paper No. 117, 24 pp, 2019 We study long time behavior of integrated trawl processes introduced by Barndorff-Nielsen. The trawl processes form a class of stationary infinitely divisible processes, described by an infinitely divisible random measure (L\'evy base) and a family of shifts of a fixed set (trawl).

On the rate of convergence in the weak invariance principle for dependent random variables with applications to Markov chains [PDF]
We prove an invariance principle for non-stationary random processes and establish a rate of convergence under a new type of mixing condition. The dependence is exponentially decaying in the gap between the past and the future and is controlled by an ...

Soft bounds on diffusion produce skewed distributions and Gompertz growth [PDF]
, 2014 Constraints can affect dramatically the behavior of diffusion processes. Recently, we analyzed a natural and a technological system and reported that they perform diffusion-like discrete steps displaying a peculiar constraint, whereby the increments of ...

An evaluation of flow-routing algorithms for calculating contributing area on regular grids [PDF]
Earth Surface DynamicsCalculating contributing area (often used as a proxy for surface water discharge) within a digital elevation model (DEM) or landscape evolution model (LEM) is a fundamental operation in geomorphology.

Markov Processes, Hurst Exponents, and Nonlinear Diffusion Equations with application to finance [PDF]
, 2006 We show by explicit closed form calculations that a Hurst exponent H that is not 1/2 does not necessarily imply long time correlations like those found in fractional Brownian motion.

Incrementality Bidding via Reinforcement Learning under Mixed and Delayed Rewards [PDF]
arXiv, 2022 Incrementality, which is used to measure the causal effect of showing an ad to a potential customer (e.g. a user in an internet platform) versus not, is a central object for advertisers in online advertising platforms. This paper investigates the problem of how an advertiser can learn to optimize the bidding sequence in an online manner \emph{without ...
