A decomposition scheme was applied to ALOS/PALSAR data obtained from a fast-growing tree plantation in Sumatra, Indonesia to extract tree stem information and then estimate the forest stand volume. The scattering power decomposition of the polarimetric SAR data was performed both with and without a rotation matrix and compared to the following field-measured forest biometric parameters: tree di...

AIM To assess the eventual influence of low dose betamethasone throughout pregnancy on fetal growth. PATIENTS AND METHODS 320 patients - admitted to the Section of Obstetrics and Gynecology of Ferrara University from January 2005 to December 2010 - were subdivided in two groups: 160 patients affected by recurrent spontaneous abortion (Group A), treated by low dose of betamethasone (0.5 mg/dai...

BACKGROUND The aim of this study was to assess the intraocular pressure and ocular biometric parameters in migraine patients during acute migraine attacks and compare them with painless period and healthy controls using a new optical biometer AL-Scan. METHODS In this prospective, case-control study, the axial length, corneal curvature radius, anterior chamber depth, central corneal thickness,...

Purpose. To obtain information about effect of cycloplegia on keratometry and biometry in keratoconus. Methods. 48 keratoconus (Group 1) and 52 healthy subjects (Group 2) were included in the study. We measured the flat meridian of the anterior corneal surface (K1), steep meridian of the anterior corneal surface (K2), lens thickness (LT), anterior chamber depth (ACD), and axial length (AL) usin...

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Speckle tracking echocardiography is an upcoming modality to quantify left atrial function. Left function disturbed in many disease and systolic strain (LASr) has already been associated with the prognosis fibrillation degree diastolic dysfunction. Some modifying parameters have identified relatively small studies. Pu...

Traditional biometric systems that based on single biometric usually suffer from problems likeimposters' attack or hacking, unacceptable error rate and low performance. So the need of using multimodal biometric system occurred .In this paper, a study of multimodal palm veins and signature identification is presented.Features of both modalities are extracted by using morphological operations and...

Different biometric traits such as face appearance and heartbeat signal from Electrocardiogram (ECG)/Phonocardiogram (PCG) are widely used in the human identity recognition. Recent advances in facial video based measurement of cardio-physiological parameters such as heartbeat rate, respiratory rate, and blood volume pressure provide the possibility of extracting heartbeat signal from facial vid...
