Failure Analysis and Maintenance Planning for Repairable Deteriorating Structural Systems Subject to Imperfect Maintenance

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 3, Page 992-1008, April 2026.
ABSTRACT The analysis of a system that deteriorates under imperfect maintenance is essential in reliability engineering. Imperfect maintenance does not fully restore a system to its original condition, leading to complex degradation patterns. Statistical inference techniques allow for precise estimation of degradation parameters, maintenance effects ...

Statistical Analysis of Time-Varying Characteristics of Testability Index Based on NHPP

open access: yesIEEE Access, 2017
The failure detection rate (FDR) is the most common testability index used to evaluate the equipment testability level. According to the testability test theory of FDR, a widespread supposition is that the FDR value of a system is an unknown constant ...

And then there were none: decrease of origination and the decline of Conulariida

open access: yesPapers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract Although the evolutionary history of conulariids has been widely studied, previous works have focused mostly on limited time intervals. In this paper, we examine the diversity dynamics of the group throughout its entire history, using various mathematical approaches.

Analysis of Failures, Downtimes and Reliability of Wind Turbines From SCADA Data

open access: yesWind Energy, Volume 28, Issue 12, December 2025.
ABSTRACT With the growing demand for safe, efficient and reliable sustainable energy sources, wind energy has witnessed rapid growth worldwide in recent years. Reliability is critical to the operational performance of the wind turbines. Reliability analysis allows for the critical subassemblies to be identified and better maintenance strategies to ...

Flexible movement kernel estimation in habitat selection analyses with generalized additive models

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 8, Page 1796-1807, August 2025.
Abstract Habitat selection analysis includes resource selection analysis (RSA) and step selection analysis (SSA). These frameworks are used in order to understand space use of animals. Particularly, the SSA approach specifies the area available to the animal through a movement kernel.

Next Generation Models for Subsequent Sports Injuries

open access: yesApplied Stochastic Models in Business and Industry, Volume 41, Issue 4, July/August 2025.
ABSTRACT This paper contributes a modelling approach for prediction of subsequent injury risk using longitudinal wearable data in the sports industry. Understanding subsequent injury events in sport, namely injuries that follow an initial injury, will assist athletes, support staff, and coaches to quantify the risk of future injury and better inform ...

Reliability Analysis of Repairable Systems Based on a Two-Segment Bathtub-Shaped Failure Intensity Function

open access: yesIEEE Access, 2018
The reliability analysis of complex repairable systems is an important but computationally intensive task that requires fitting the failure data of whole life cycles well.

Is There a Future for Stochastic Modeling in Business and Industry in the Era of Machine Learning and Artificial Intelligence?

open access: yesApplied Stochastic Models in Business and Industry, Volume 41, Issue 2, March/April 2025.
ABSTRACT The paper arises from the experience of Applied Stochastic Models in Business and Industry which has seen, over the years, more and more contributions related to Machine Learning rather than to what was intended as a stochastic model. The very notion of a stochastic model (e.g., a Gaussian process or a Dynamic Linear Model) can be subject to ...

Modelling of Risk Process With Expense‐Augmented Loss Under Economic Factors and Its Application to Aggregated General Insurance Data in Kenya

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
In this paper, we reformulate the classical risk model to consider economic factors such as taxation and real force of interest. In the model, the premiums are assumed to be compounded by increasing annuities over some time. The loss process is also presumed to be two mixed stochastic processes with weights that sum to 1.

Seismic Response of Hectometer‐Scale Fracture Systems to Hydraulic Stimulation in the Bedretto Underground Laboratory, Switzerland

open access: yesJournal of Geophysical Research: Solid Earth, Volume 129, Issue 11, November 2024.
Abstract We performed a series of hydraulic stimulations at 1.1 km depth in the Bedretto underground laboratory, Switzerland, as part of an overall research strategy attempting to understand induced seismicity on different scales. Using an ultra‐high frequency seismic network we detect seismic events as small as Mw < −4, revealing intricate details of ...
