Lumen Degradation Lifetime Prediction for High-Power White LEDs Based on the Gamma Process Model

Nowadays, due to the advancement of design and manufacturing technology, there are many consumer products with high reliability. Similarly, the competition in the business sector influences the product development time to become shorter and that makes it difficult for manufacturers to evaluate the reliability of current products before new...

Gamma distribution models for transit time estimation in catchments: Physical interpretation of parameters and implications for time?variant transit time assessment

In hydrological tracer studies, the gamma distribution can serve as an appropriate transit time distribution (TTD) as it allows more flexibility to account for nonlinearities in the behavior of catchment systems than the more commonly used exponential distribution. However, it is unclear which physical interpretation can be ascribed to its two...
