It may be more economical to replace an appliance than to repair it, when cost, life expectancy, and efficiency are considered.
Ultraviolet light emitting diodes (UV-LEDs) are attracting the interest of researchers for the design of compact photoreactors due to their energy efficiency, life expectancy, design flexibility, and easily tuned intensity and emission wavelength.
In any case, the system energy efficiency and life expectancy of batteries may be improved only if an energy management strategy is applied to control the power flows (or load distribution) in the hybrid battery/ultra-capacitor ESS.
Increased tumor control efficiency and life expectancy augment the risk to develop radiation sequels in patients in whom cure has been achieved.
From energy-efficiency to life expectancy to finding a date or something to do on a Saturday night, Mr. Glaeser argues that denser places have the edge.
While this model was developed to address efficiency concerns and maximize life expectancy per cohort, instances could arise in which concerns about equity override efficiency.
Gearhart [8] noted that efficiency results were similar when utilizing DALY or life expectancy, so for methodological simplicity, life expectancy was chosen as the output measure.
With more modest capacity increases over time, discontinuing treatment not only maximizes life expectancy per cohort, but also allows more individuals to receive treatment, improving both efficiency and equity.
The SOFC has the highest efficiencies of all fuel cells and, potentially, a long life expectancy.
Moreover, this study concerns the effectiveness and efficiency of cancer services relative to the other MDC and not life expectancy per se, which now finds England and Wales exceeding the USA and a number of other MDC (US Bureau Statistics, 2009).
