Organic Photovoltaic Device Model is a 1D Schottky-Read-Hall based drift diffusion model specifically designed to model organic photovoltaic (OPV) devices. It can describe non-geminate recombination via two mechanisms: free-to-trap processes via an exponential tail of trap states, and free-to-free carrier processes. The model solves the drift diffusion equations for electrons and holes, Poisson's equation to calculate the potential distribution in position space, and the Schottky-Read-Hall capture escape equations for a discretized set of energy levels. The model has been used to generate a number of publications. It can simulate the following experiments often used to characterize OPV devices: JV curves (Light/Dark), Charge extraction data (Light/Dark), and Steady state recombination data (Light/Dark).
facedetect is a simple face detector for batch processing. It answers the basic question: "Is there a face in this image?" and gives back either an exit code or the coordinates of each detected face in the standard output. It aims to provide a basic command-line interface that's consistent and easy to use with software such as ImageMagick, while progressively improving the detection algorithm over time.
Cloudprint-service adds a service to your Linux computer that makes your printers available via Google Cloud Print. This can make the printer persistently available to other users, other devices, or other sites, under your control. No special printer drivers are needed to access the shared print queue.
decotengu is a dive decompression library to experiment with various implementations of the Buhlmann decompression model with Erik Baker’s gradient factors. The results of decotengu calculations are decompression stops and tissue saturation information. Third party applications can use those results for data analysis purposes or dive planning functionality.
