The main objective of accelerated life tests in this setting is the recovery of the distribution of the random variable representing lifetime which is difficult to observe at a certain level of a given stress factor. A general model for accelerated life test is proposed that utilizes the inverse problem approach, that is, the variable is observe at different level/s and the transfer function is...

Reliability is one of the main salient assets of modern electronic systems and its improvement is of utmost importance in manufacturingof high-reliability electronic products. The only possible means of improving the operational characteristics of electronic systems and reducing their overall lifecycle costs is improving their reliability. This is possible through designing in reliability at th...

The useful life of an LED is presently determined by the IESNA LM80-08 lumen maintenance standard. Even though an LED system has many components, the current industry practice rates LED system lifetime based on a single component, namely, the LED. LED system life is one of the least understood parameters, especially in application environments. As a result, any lifetime claim for a complete LED...

When we talk about environmental justice, we mean calling a halt to the poisoning of our poorest communities, from our rural areas to our inner cities. We don’t have a person to waste and pollution clearly wastes human lives and natural resources. When our children’s lives are no longer damaged by lead poisoning, we will stop wasting the energy and intelligence that could build a stronger and m...

Industries such as telecomm and avionics have long enjoyed a perk that most other industries do not enjoy: access to accurate operational profiles. Most other industries are left hypothesizing about how they believe the majority of their users will interact with a particular software package. If these guesses are wrong, reliability predictions based on the guesses will likely be wrong as well. ...

Calls for „holistic‟ responses to halt the increasing imprisonment of women are continually reiterated. Solutions are sought which aim to be both „gender-responsive‟ and „community-based‟, however the absence of meaningful definitions of „community‟ and „holistic‟ means that superficial responses are often put in place in response to failures of the system. Taking as an example one attempt to i...

In this study the focus is on the role of local communities in the management of protected areas with the expectation that without the cooperation and assistance of local communities achieving biodiversity conservation in places where the land and resources are fundamental to supporting people’s livelihoods will be less successful than if the local people actively support this goal. Management ...

To obtain the characteristic life of a chain tool magazine and automatic tool changer under normal working condition, a small-sample accelerated life test method was developed. The inverse power law model and small-sample virtual augmented theory was applied while taking vibration as the accelerated stress. The accelerated life test of the automatic tool changer was carried out under different ...
