Differential power processing for increased solar array energy harvest
… solar simulator is developed which models annual energy production for arrays with and without DPP. Models for expected sources of loss are implemented to determine any improvement DPP offers over conventional methods. Two common and predictable sources of mismatch are self-shading and diffuse …

LOW-POWER LOW-VOLTAGE ANALOG CIRCUIT TECHNIQUES FOR WIRELESS SENSORS
… require battery are more preferred. Such sensors harvest energy from energy sources in the environment such as radio frequency (RF) waves, vibration, thermal sources, etc. As a result, the obtained energy is very limited. This creates strong demand for low power, lower voltage circuits. The RF and …

The gut microbiome of the western lowland gorilla (Gorilla gorilla gorilla): implications for overall ecology
… gorillas face foraging challenges associated to energy harvest across seasons. As such, I propose that, along with behavioral and physiological adaptations, gut bacteria contribute significantly to gorilla foraging plasticity. In chapter 4, a compositional and functional comparison with gut …
