Stress-related biophysical variables of capital intensive orchard crops can be estimated with proxies via spectral vegetation indices from off-nadir viewing satellite imagery. However, variable viewing compositions affect the relationship between spectral vegetation indices and stress-related variables (i.e., chlorophyll content, water content and Leaf Area Index (LAI)) and could obstruct chang...

mother's mental health status during pregnancy has important effects on fetal growth and development. however, there are few studies concerning association of maternal depression and biophysical profile (bpp) of the fetus. we performed this research to know if maternal depression has any association with fetal bpp score. for measuring depression, farsi version of patient health questionnaire-9 ...

Remote sensing of biophysical variables is a key step for the quantification of the carbon fluxes of forests. Forests are rather challenging targets, due to their architectural heterogeneity, understory vegetation effect, plant shadows, etc. [1] This work evaluated empirical predictive models between vegetation indices (VI) derived from IRS LISS-III 4-band (1: 0.520.59, 2: 0.62-0.68, 3: 0.77-0....

BACKGROUND The foetus has become increasingly accessible and visible as a patient over the last two decades. Ultrasound imaging has broadened the scope of foetal assessment. Dynamic real time B-Mode ultrasound is used to monitor cluster of biophysical variables, both dynamic and static collectively termed as biophysical profile. The purpose of this study was to determine the effect of sonograph...

Objective: one of the best tests for the assessment of a fetus is the biophysical profile test which has a significant effect on fetus health and the outcome of pregnancy. The present study was designed to determine the relationship between the full biophysical profile and the rapid biophysical profile tests in antepartum fetal surveillance. Patients and Methods: In this prospective study, Sin...

The accurate estimation of canopy biophysical variables at sufficiently high spatial and temporal resolutions is a key requirement for operational applications in the agricultural sector. In this study, recently available multispectral RapidEye sensor data were tested for their operational suitability to estimate canopy biophysical variables in the Italian Campania region. For this purpose, two...

In this paper, we present a theoretical and modeling framework to estimate the fractions of photosynthetically active radiation (PAR) absorbed by vegetation canopy (FAPARcanopy), leaf (FAPARleaf ), and chlorophyll (FAPARchl), respectively. FAPARcanopy is an important biophysical variable and has been used to estimate gross and net primary production. However, only PAR absorbed by chlorophyll is...
