Novel Computerized Method for Measurement of Retinal Vessel Diameters
Several clinical studies reveal the relationship between alterations in the topologies of the human retinal blood vessel, the outcrop and the disease evolution, such as diabetic retinopathy, hypertensive retinopathy, and macular degeneration. Indeed, the detection of these vascular changes always has gaps. In addition, the manual steps are slow, which may be subjected to a bias of the perceiver...
متن کاملEffective Point of Measurement in Cylindrical Ion Chamber for Megavoltage Photon Beams
Introduction For dose measurement in Megavoltage (MV) photon beams with ion chambers, the effect of volume occupied by the air cavity is not negligible. Therefore, the result of measurement should be corrected with a displacement perturbation correction factor (Pdis) or using an effective point of measurement (EPOM). The aim of this study is to calculate the EPOM for cylindrical ion chamber and...
متن کاملStudy on Fundamental Frequencies of Cylindrical Storage Tanks Obtained from Codes and Finite Element Method
In the case of study on the seismic behavior of tanks, one of the most important subjects is selection of convective and impulsive frequencies for storage tanks. These two frequencies are defined by Housner. The major utility of these frequencies is for Rayleigh damping which is a must for time history analysis. API 650, EUROCODE 8 have suggested some analytical solutions for finding convective...
متن کاملAutomatic Control Point Measurement
Nowadays the tenor of reports on applications of digital photogrammetric procedures consists of a unison message: processing modules of automatic image orientation are available in digital photogrammetric systems and with them the productivity is much higher than with all existing conventional photogrammetric plotters. In fact, interior and relative orientation procedures as well as automated a...
متن کاملAutomatic Control Point Measurement
The measurement of ground control points is an important task for the absolute orientation of stereo models, for digital aerial triangulation or for the registration of satellite imagery. In the Digital Photogrammetric Systems existing today this task is usually completely performed by a human operator. There exist, however, methods, that can identify and/or localize control points or control s...
