Study of energy loss, range, and stopping time for proton in germanium and copper materials

Open Engineering
In this study, the energy loss, range, and stopping time were calculated using the Bethe theory for protons in germanium and copper materials over an energy range of 0.01–1,000 MeV.

Influence of key factors on vehicle braking

Taikomieji Moksliniai Tyrimai, 2022
The article analyzes the influence of the driver's reaction time, the speed of the car's movement and the road surface on the length of the car's stopping and stopping distance.

The practice of going helps children to stop:The importance of context monitoring in inhibitory control [PDF]

, 2014
How do we stop ourselves during ongoing action? Recent work implies that stopping per se is easy given sufficient monitoring of contextual cues signaling the need to change action.

Product Depth for Truncated Temporal Point Processes

Data Science in Science
Temporal point process data arise in many applications, such as neuroscience and finance, where the focus is on the timing of sequential events. In many settings, however, observations are collected under an event-driven stopping mechanism, where ...

On simple representations of stopping times and stopping time sigma-algebras [PDF]

Statistics & Probability Letters, 2013
Abstract There exists a simple, didactically useful one-to-one relationship between stopping times and adapted cadlag (RCLL) processes that are non-increasing and take the values 0 and 1 only. As a consequence, stopping times are always hitting times.

On a Solution of the Optimal Stopping Problem for Processes with Independent Increments [PDF]

We discuss a solution of the optimal stopping problem for the case when a reward function is a power function of a process with independent stationary increments (random walks or Levy processes) on an infinite time interval.

On recursive stopping of decimation of discrete-time bandlimited signals

Lietuvos Matematikos Rinkinys, 2011
For each non-decimated as well as decimated realization discrete-time Fourier series coefficient values, located at Nyquist frequency are calculated, using original speedy recursive expressions based on reverse order processing of the given realizations.

The Optimal Stopping Problem of Dupuis and Wang: A Generalization [PDF]

In this paper, we study the optimal stopping problem of Dupuis and Wang analyzed in [7]. In this problem, the underlying follows a linear diffusion but the decision maker is not allowed to stop at any time she desires but rather on the jump times of an ...

On Infinite Horizon Optimal Stopping of General Random Walk [PDF]

The objective of this study is to provide an alternative characterization of the optimal value function of a certain Black- Scholes-type optimal stopping problem where the underlying stochastic process is a general random walk, i.e.

Some aspects of statistical causality

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Causal thinking is deeply embedded in scientific understanding of the problems of applied statistics. This can not always be done by experiments and the researcher is restricted to observing the system he wants to describe.
