Our homes are microbial habitats, and although the amounts and types of bacteria in indoor air have been shown to vary substantially across residences, temporal variability within homes has rarely been characterized. Here, we sought to quantify the t

A method is proposed for the experimental characterization of through-the-thickness damage propagation in multidirectional carbon fiber reinforced polymer laminates. The compact tension specimen configuration is used to propagate damage stably while

The effect of voltage ripple on the power output of a photovoltaic panel is calculated and tested experimentally. Voltage ripple induces a much larger power reduction than would be predicted from a conventional small-signal model of the panel's I-V c
