Nonparametric Accelerated Life Testing

IEEE Transactions on Reliability, 1982
This paper considers the problem of nonparametric accelerated life testing by extending the results of Shaked & Singpurwalla in two directions. First we solve the case of censored data. Next we extend the methods to the case of competing risks. A s-consistent estimate of the failure distribution at use-stress is given for both cases.

Development of Accelerated Life Test

2008 IEEE Conference on Robotics, Automation and Mechatronics, 2008
This paper summarizes the development of accelerated life test types, model, statistical method and its progress. To the mechatronic component whose failure mechanism is related to various operational stresses, the best way is to exploit variable stress accelerated life test (ALT), obtain the likelihood function with failure accumulative method, and ...

Accelerated life tests of ceramic capacitors

38th Electronics Components Conference 1988., Proceedings., 1988
Multilayer capacitors prepared from three different ceramics were tested under highly accelerated conditions of both voltage and temperature. Three types of breakdown were encountered: avalanche, fast thermal degradation, and diffusion or wearout. The goal was to determine whether data from highly accelerated life tests could be used to plot failure ...

A Software Accelerated Life Testing Model

2010 IEEE 16th Pacific Rim International Symposium on Dependable Computing, 2010
Software system developed for a specific user under contract undergoes a period of testing by the user before acceptance. This is known as user acceptance testing and is useful to debug the software in the user's operational circumstance. In this paper we first present a simple non-homogeneous Poisson process (NHPP)-based software reliability model to ...

Accelerated Life Test and Life Prediction of an Electromechanical Actuator

2019 International Conference on Artificial Intelligence and Advanced Manufacturing (AIAM), 2019
This paper gives an accelerated test method for electromechanical actuator (EMA) and predicts its life based on Wiener process degradation model. According to the historical fault data and the FMECA analysis, we obtain that the key weak links of the electromechanical actuators are the electromagnetic clutch and the tachogenerator.

Accelerated Life Tests and Information

Radiation Research, 1982
BARLOW, R. E. Accelerated Life Tests and Information. Radiat. Res. 90, 90-97 (1982). This is a partly philosophical discussion of the problems of conducting accelerated life test experiments and analyzing data from such experiments. The objective is to predict life at a specified stress level or radiation dose.

Accelerated Life Testing and Aging

2022
Abstract Accelerated life testing and aging methodologies are increasingly being used to generate engineering data for determining material property degradation and service life (or fitness for purpose) of plastic materials for hostile service conditions.

On a bivariate accelerated life test

Journal of Statistical Planning and Inference, 1987
Consider a product which consists of two dependent components whose lifetimes follow the bivariate exponential distribution of \textit{H. W. Block} and \textit{A. P. Basu}, J. Amer. Statist. Assoc. 69, 1031-1037 (1974; Zbl 0299.62027). Maximum likelihood estimation of the parameters of the joint distribution of the lifetimes is discussed when the data ...

Accelerated Life Testing

2014
Methods of accelerated life testing are applied to several kinds of progressively censored data. This includes step-stress testing as well as progressive stress models.
