It is forecasted that two out of three persons in the world will be water stressed by the year of 2025 (EPA 1998). Proper management of water resources at watershed scale may offer the best solutions for water shortage and contamination. The objective of the research is to conduct reactive flow simulations in surface-subsurface, coupled flow systems using a(More)
This paper presents a wireless on-lens intraocular pressure monitoring system, comprising a capacitance-to-digital converter and a wirelessly powered radio-frequency identification (RFID)-compatible communication system, for sensor control and data communication. The capacitive sensor was embedded on a soft contact lens of 200 μm thickness using(More)
This study presented a wireless smart contact lens system that was composed of a reconfigurable capacitive sensor interface circuitry and wirelessly powered radio-frequency identification (RFID) addressable system for sensor control and data communication. In order to improve compliance and reduce user discomfort, a capacitive sensor was embedded on a soft(More)

This paper presents the development and application of a bay/estuary model to simulate hydrodynamics and salinity transport. The hydrodynamic module solves three-dimensional Navier-Stokes equations with or without the hydrostatic assumptions. The Boussinesq approximation is employed to deal with the buoyancy force due to temperature and salinity variations.(More)
