Modeling the Role of Testing Coverage in the Software Reliability Assessment [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2023
To assure the reliability and quality of the final product, testing is an essential and crucial part in the software development cycle. During this process, fault correction/detection activities are carried out to increase the reliability of the software.

The fractional non-homogeneous Poisson process [PDF]

open access: yes, 2017
We introduce a non-homogeneous fractional Poisson process by replacing the time variable in the fractional Poisson process of renewal type with an appropriate function of time.

Accounting for unobserved spatial variation in step selection analyses of animal movement via spatial random effects

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 10, Page 2639-2653, October 2023., 2023
Abstract Step selection analysis (SSA) is a common framework for understanding animal movement and resource selection using telemetry data. Such data are, however, inherently autocorrelated in space, a complication that could impact SSA‐based inference if left unaddressed.

A Bayesian reliability analysis exploring the effect of scheduled maintenance on wind turbine time to failure

open access: yesWind Energy, Volume 26, Issue 9, Page 879-899, September 2023., 2023
Abstract This article presents a Bayesian reliability modelling approach for wind turbines that incorporates the effect of time‐dependent variables. Namely, the technique is used to explore the effect of annual services on wind turbine failure intensity through time for turbines within a currently operational wind farm.

Imperfect repair models: Sequential goodness‐of‐fit testing based on predictive performances

open access: yesQuality and Reliability Engineering International, Volume 39, Issue 2, Page 609-629, March 2023., 2023
Abstract Imperfect repair (IR) modelling has attracted a lot of attention during the last decades. To assess and predict repairable systems' reliability, analysts have to choose among a plethora of models: renewal processes, non‐homogeneous Poisson processes (NHPPs), Brown–Proschan, Kijima, ARA, ARI, Quasi‐Renewal (QR), Trend‐Renewal and so forth ...

Field‐data‐based reliability analysis of power converters in wind turbines: Assessing the effect of explanatory variables

open access: yesWind Energy, Volume 26, Issue 3, Page 310-324, March 2023., 2023
Abstract Frequent failures of power converters affect the availability of wind turbines and cause considerable maintenance costs. To enhance the reliability of power converters in wind turbines, the prevailing causes and modes of failures have to be identified.

Forecasting Warranty Claims for Recently Launched Products [PDF]

open access: yes, 2012
Forecasting warranty claims for recently launched products that have short histories of claim records is vitally important for manufacturers in preparing their fiscal plans. Since the amount of historical claim data for such products is not large enough,

A Counting Process Approach for Trend Assessment of Drought Condition

open access: yesHydrology, 2019
This paper discusses some methodological aspects of the historical analysis of drought, particularly the trend assessment. The Standardized Evapotranspiration Index (SPEI) is widely used as a measure of drought condition.
