Application of the Variational Fracture Model to Hydraulic Fracturing in Poroelastic Media
… are designed without considering poroelastic effects even though a propagating hydraulic fracture induces deformation of the surrounding porous media. A rigorous hydraulic fracturing model capable of reproducing realistic fracture behaviors should couple rock deformation, fracture propagation …

Enabling Hybrid Optical-Microwave Space Communications with Optically Transparent RF Components Using Indium Tin Oxide (ITO)
… metal-based antennas—particularly their shadowing effect on satellite solar cells—this study investigates ITO as a pivotal material for creating antennas that are both efficient in communication and non-intrusive to solar efficiency. Utilizing 4-point probes and coplanar waveguide (CPW) …

Mechanisms for intrinsic stress evolution during and after polycrystalline film growth
… at grain boundaries. We also investigated the effect of the angle of incidence of the flux of depositing atoms on stress and structure evolution during polycrystalline film growth. We find that as the angle of incidence increases, the coalescence thickness increases and the stress becomes less …

HIGH PERFORMANCE NANOPHOTONIC CAVITIES AND INTERCONNECTS FOR OPTICAL PARAMETRIC OSCILLATORS AND QUANTUM EMITTERS
… source to new wavelengths. However, parasitic effects normally limit the output power and conversion efficiency of χ(3)microring OPOs. This issue is resolved by using a microring geometry with strongly normal dispersion to suppress parasitic processes and multiple spatial mode families to …

A systematic study of ion-induced nanopatterning on photonic crystal-based label-free optical biosensor
… these pre-existing structures may have a shadowing effect, causing non-uniform sputtering of the surface, and resulting in variations of surface topography on different areas of the pre-existing structures, as well as affecting the PC’s ability to resonate and reflect light due to possible …

Improving Bluetooth-based Indoor Positioning Using Vision and Artificial Networks
… while ubiquitous in outdoor positioning, are not effective indoors. One of the best solutions to solve this problem and increase the accuracy of the user's position in indoor areas is to apply other sensors. This research takes advantage of Bluetooth Low Energy (BLE) technology, vision systems, …
