The optical coupling between dual elements of photonic crystal vertical cavity surface emitting laser arrays is characterized. optically coupled microcavity lasers have independent bias injection currents. Output power and beam analysis measurements are used to quantify the effects coherence in nominally 850 nm arrays. Modelling experiment show how influenced by lattice period current into elem...

Modeling the injection of CO 2 and its sequestration will require simulations of a multi-well injection system in a large reservoir field. However, modeling at the injection well scale is a necessary prerequisite to reservoir scale modeling. We report on the development and application of two models: 1) a semi-analytical model (PNLCARB), and 2) a numerical model (STOMP-CO 2). PNLCARB can simula...

We evaluated the efficacy of the systemic insecticides dinotefuran, emamectin benzoate, fipronil, and imidacloprid for preventing attacks and brood production of southern pine engraver beetles (Coleoptera: Curculionidae: Scolytinae) and wood borers (Coleoptera: Cerambycidae) on standing, stressed trees and bolt sections of loblolly pine, Pinus taeda L., in eastern Texas. Emamectin benzoate sign...

The combined well pattern has been widely used in reservoir development, with a common being horizontal the center for oil production and multiple vertical wells around water injection. For this type of pattern, determining is affected by which injection wells, especially when injecting breaks through, accurately direction inflow will provide an important basis targeted measures. Based on perfo...

Sequestration of carbon dioxide in geologic formations, both deep aquifers and depleted petroleum reservoirs, has the potential to signi...cantly reduce the atmospheric emissions of that greenhouse gas. Injection into a deep saline formation di¤ers from injection into a hydrocarbon reservoir in that there is no produced ‡uid from the aquifer and the hydrogeologic characterization of both the re...

In this work, a microfluidic chip-based valveless flow injection analysis (FIA) system with gravity-driven flows and liquid-core waveguide (LCW) spectrometric detection was developed. Automated sample injection in the 0.3-6.4 nL range under gated injection mode was achieved by controlling the vertical position of the waste reservoir fixed on a moving platform and the residence time of the reser...

Abstract: Additional entropy generation rates through non-equilibrium ordered structures are predicted for corner flows with sidewall mass injection. Well-defined non-equilibrium ordered structures are predicted at a normalized vertical station of approximately eighteen percent of the boundary-layer thickness. These structures are in addition to the ordered structures previously reported at app...

Injection-induced rock mechanical failure risks are critical in CO2 sequestration, and thus there is a need to evaluate these occurrences ensure safe reliable subsurface storage. A stress–strain-based numerical simulation can reveal the potential of any sites. This study investigated hydromechanical effect on geomechanical due injection-induced stress pore pressure changes prospective storage s...
