[1] Prediction of flow through variably saturated porous media requires accurate knowledge of the soil hydraulic properties, namely the water retention function (WRF) and the hydraulic conductivity function (HCF). Unfortunately, direct measurement of the HCF is time consuming and expensive. In this study, we derive a simple closed-form equation that predicts the saturated hydraulic conductivity...

Ultrafast superconductor digital microelectronic circuits operate at speeds up to 100 GHz, enabling true digital-RF architecture. This permits direct conversion between analog RF and digital baseband signals, replacing frequency and protocol-specific analog hardware with flexible, software-programmable digital processors. On the receive side, high sampling-speed (20 Gsamples/s) and linearity (>...

When calculating of the moisture transport in concrete such geotechnical structures as a pile or diaphragm wall, contact with soil is forming special boundary conditions. If full saturated state, then Darcy’s law should be used to solve problem, condition for which water pressure. Otherwise, Bažant- Najjar model used, relative humidity environment at certain temperature. The temperature unique ...

In this project, we proposed to develop and investigate a sensitive microwave sensor based on a two-cell SQUID by imitating the operational principle of the fly's ears. The fly ormia shows astonishing localization ability with its tiny hearing organ. In this report, we show first measurement results based on several available Josephson junction (JJ) circuits. We investigated the current-voltage...

Europe. A total of 660, 522, and 4940 soil samples belonging to GRIZZLY, HYPRES, EU-HYDI databases, respectively, were used for parametric evaluation. The water retention hydraulic conductivity functions are crucial input information land surface models. Determining these by using direct methods is hampered excessive time unaffordable costs required field activities laboratory analyses. Pedotra...
