A new lifetime distribution capable of modeling a bathtub-shaped hazard-rate function is proposed. The proposed model is derived as a limiting case of the Beta Integrated Model and has both the Weibull distribution and Type I extreme value distribution as special cases. The model can be considered as another useful 3-parameter generalization of the Weibull distribution. An advantage of the mode...

This paper presents a reliability analysis for electronic devices (ED) with bathtub curve-shaped failure times. An extension of the exponentiated perks distribution (EPD) is proposed analysis. The this new based on Alpha Power Transformation, so Exponentiated Perks Distribution (AEXP) introduced. AEXP has three shape parameters and one scale parameter, allowing greater flexibility to represent ...

A new two-parameter lifetime distribution is proposed and numerically studied. The model has a flflexible failure rate shapes such as “monotonically increasing” , decreasing” “bathtub” “constant” “upside down” “J-shape” . Various of its statistical properties are derived. numerical analysis skewness kurtosis presented. Many bivariate multivariate extensions also presented via Farlie Gumbel Morg...

In this paper, we propose a new extension of the traditional Rayleigh distribution called modified Kies distribution. The contains one scale and shape parameter its hazard rate function can be increasing bathtub-shaped. Some mathematical properties are derived including quantiles moments. parameters estimated based on progressively Type-II censored data. For purpose, consider two estimation met...

BACKGROUND Taking a bath sometimes poses a risk for subjects with chronic cardiopulmonary disorders, due to the thermal effect and water pressure on his/her body. The ECG measurement would be helpful for the early recognition of abnormal cardiac beats and respiratory conditions. This paper describes a new attempt to improve on previous bathtub ECG measurement techniques that had electrodes plac...

Reliability evaluations and assurances cannot be delayed until the device (system) is fabricated put into operation. of an electronic product should conceived at early stages its design; implemented during manufacturing; evaluated (considering customer requirements existing specifications), by electrical, optical mechanical measurements testing; checked (screened) fabrication; and, if necessary...
