We propose accurate and computationally efficient procedures to calibrate fluorescence microscopes from micro-beads images. The designed algorithms present many original features. First, they allow estimate space-varying blurs, which is a critical feature for large fields of views. Second, we novel approach calibration: instead describing an optical system through single operator, suggest vary ...

Rapid infiltration following precipitation may result in groundwater contamination from surface contaminants or pathogens. In fractured rock, can migrate rapidly to points of withdrawals. contrast the temporal availability quality chemical indicators, meteorological and level observations are available real-time estimate time-varying recharge, which act as a surrogate identify periods rapid tha...

This study analyzes the soil water infiltration characteristics under muddy irrigation and bio-organic fertilizer conditions in current context of rarely being used agricultural production combination with problems resource shortages low fertility arid semi-arid regions. An indoor one-dimensional column device was for studying effects four sediment concentration levels (ρ0: 0; ρ1: 4%; ρ2: 8%; ρ...

Abstract Greater complexity in three-dimensional (3D) model structures yields more plausible groundwater recharge/discharge patterns, especially groundwater/surface-water interactions. The construction of a 3D hydrostratigraphic prior to flow modelling is beneficial when the hydraulic conductivity geological units varies considerably. A workflow for with Leapfrog Geo and MODFLOW-NWT was develop...

unsaturated hydraulic conductivity, K, expressed as a function of the soil water content, u, or the soil water Hysteresis has been found in both the hydraulic conductivity, K, pressure head, c, and the relation between u and c must vs. pressure head, c, relationship, and the soil water content, u, vs. c relationship. This limits the application of a unified solution for be specified before anal...

This paper reports recent results from studies of atomic layer deposition for the infiltration of three-dimensional photonic crystals. Infiltration of ZnS:Mn and TiO2 are reported for SiO2-based opal templates. It has been demonstrated that high filling fractions can be achieved and that the infiltrated material can be of high crystalline quality as assessed by photoluminescence measurements. T...
