Weibull Variational Autoencoder for Remaining Useful Life Prediction

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Remaining useful life (RUL) prediction is a critical technology for preventing unexpected failures and reducing maintenance costs in modern industrial systems. However, traditional model‐based approaches are limited by the need for explicit mathematical modeling of degradation mechanisms, while data‐driven methods often require large‐scale ...

Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels

steel research international, EarlyView.
The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

Characterizations of Lifetime Distributions Using Two Relative Reliability Measures

Journal of Function Spaces, 2022
In this paper, a general characterization property considering two new dynamic relative reliability measures is obtained. The new dynamic relative reliability measures are expressed as the ratio of hazard rates and as the ratio of reversed hazard rates ...

Kernel Inference on the Inverse Weibull Distribution [PDF]

Communications for Statistical Applications and Methods, 2006
In this paper, the Inverse Weibull distribution parameters have been estimated using a new estimation technique based on the non-parametric kernel density function that introduced as an alternative and reliable technique for estimation in life testing models.

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges

Structural Concrete, EarlyView.
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

A new trigonometric-inspired probability distribution: A simulation study and applications in reliability and hydrology

Alexandria Engineering Journal
The importance of statistical distributions in accurately representing real-world scenarios and aiding in educated decision-making is well recognized. Nonetheless, it is also true that the limitations of these distributions can hinder optimal fitting in ...

Parameter Estimation and Data Analysis Using a Novel Extension of Weibull Distribution [PDF]

The Egyptian Statistical Journal
Recently, statistical modeling has become essential for analyzing real-world datasets across various fields. However, classical statistical distributions often lack the flexibility to capture the complexity of observed phenomena accurately.

A probabilistic framework for modeling chloride‐induced corrosion and related load‐deformation behaviour of reinforced concrete

Structural Concrete, EarlyView.
Abstract Chloride‐exposed reinforced‐concrete structures often suffer localized corrosion, so corrosion initiation time and average steel loss are poor indicators of structural performance. This paper presents a spatially resolved, proof‐of‐concept framework that couples diffusion‐based chloride ingress and initiation with a localized morphology model ...

Exponentiated generalized inverse Weibull distribution

Applied Mathematical Sciences, 2014
The inverse Weibull distribution can be readily applied to a wide range of situations including applications in medicine, reliability and ecology. In this article we introduce a new model of generalized inverse Weibull distribution referred to as the Exponentiated generalized inverse distribution.

Matrix Approach to Computing MTTF of a System

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
This paper proposes a new method to compute the mean time to failure (MTTF) of a system that can be expressed with a combinatorial model whose components fail with i. i. d. The key idea is to use a matrix approach that replaces every component reliability with a specific matrix and replaces every operation (addition, subtraction, multiplication, and ...
