In this paper, a simple relation between the Leimkuhler curve and the mean residual life is established. The result is illustrated with several models commonly used in informetrics, such as exponential, Pareto and lognormal. Finally, relationships with some other reliability concepts are also...

Lifetime estimation of lead–acid batteries in stand-alone photovoltaic (PV) systems is a complex task because it … battery lifetime is error-prone, thus producing values that differ substantially from the real ones. This error can indicate … is the battery charge controller, which significantly affects the lifetime of batteries. The results of the simulations …

We model the information traffic on scale-free networks considering the packets’ limited lifetime. In previous papers …>0, the traffic system is in the congestion state. With lifetime mechanism, where a packet will be removed from the … system once its lifetime ends, it is found that traffic congestion is avoided. We then introduce another order parameter λ to …

Australian happiness levels are known to decline between the age of 15 and 23 by almost 0.7 on a ten-point scale. To find out what happens before that age, we develop child-specific scales to measure the effect of personality and life satisfaction domains on childhood happiness. With an...

A Wireless Sensor Network is composed of hundreds or thousands of nodes that can be equipped with limited energy resources but can still be used over an extensive set of diverse applications such as environment monitoring, healthcare, homeland security, military surveillance, manufacturing, and...
