Human Gait Recognition Subject To Different Covariate Factors In A Multi-View Environment, Asif Asif, Mohsin I. Tiwana, Umar S. Khan, Muhammad W. Ahmad, Waqar Shahid Qureshi, Javaid Iqbal Javaid Iqbal

Articles

Human gait recognition system identifies individuals based on their biometric traits. A human’s biometric features can be grouped into physiologic or behavioral traits. Biometric traits, such as the face [1], ears [2], iris [3], finger prints, passwords, and tokens, require highly accurate recognition and a well-controlled human interaction to be effective. In contrast, behavioral traits such as voice, signature, and gait do not require any human interaction and can be collected in a hidden and non-invasive mode with a camera system at a low resolution. In comparison with other physiological traits, one of the main advantages of gait analysis is …

A Combined Electrochemical-Biological System For The Production Of Liquid Fuel From Co2, Elizabeth Hann

Link Foundation Energy Fellowship Reports

Biological photosynthesis is the origin of our liquid transportation fuels, from petroleum to corn ethanol. Biological photosynthesis has an efficiency of approximately 1% for the conversion of photons from sunlight to biomass1. Increasing the energy efficiency of biomass production (solar-to-biomass conversion) would allow for biomass, and biofuels, to be produced using less resources. Artificial photosynthesis seeks to overcome the limitations of biological photosynthesis, including low efficiency of solar energy capture and poor carbon dioxide reduction, and could provide an alternative route for biomass production. A two-step electrochemical process converts CO2 to acetate. Acetate is a soluble, two-carbon substrate that can …
