Experimental Thermal Performance Investigation of Nontracking Multiple Parabolic Trough Collector With a Single Absorber

open access: yesEnergy Science &Engineering, EarlyView.
With a mass flow rate of 0.3 kg/min, a direct solar radiation of 770.25 W/m2, and a global solar radiation of 915.25 W/m2, the maximum outlet water temperature was 63.3°C, the maximum instantaneous efficiency was 51.78%, and the average heat gain was found between 69.81 and 206.88 W, depending on mass flow rate and direct solar radiation.

Toward a theory of Bayesian experimentation in early‐stage ventures

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary The entrepreneurship literature has established the benefits of experimentation but has paid comparatively little attention to its costs. We develop a Bayesian model to illustrate the entrepreneurial choice between direct and experimental entry.
