introduction:surgeosight is a dedicated intra-operative hand-held gamma camera designed and manufactured by our team to be used for lymphoscintigraphy. although conventional gamma cameras are widely used, they lack the capability of the sentinel lymph node (sln) imaging in the operation room. like conventional gamma cameras it is necessary to calibrate surgeosight for linearity distortion, ener...

Major constraints while using motor drive system are efficiency and cost. Commutation in the conventional DC motors is carried out by commutator which is rotating part placed on the rotor and brushes. Due to these mechanical parts, conventional DC motor consist high amount of losses. Brushless DC (BLDC) Motors are very extensively used motors these days because of its advantages over convention...

This paper presents a study to calculate Pathlossusing “RF link budget analysis model” with a primary focus on a sub urban macrocell environment to calculate the pathloss during the propagation and to calculate the received signal power at receiver end and accordingly a correction factor factor will be introduced for suburban area in cost-231 hatamodel. Correction factor which is considered as ...

In this paper, a three-level integrated ac–dc converter with power factor correction is presented. The proposed converter integrates the operation of the boost power factor correction and the three-level dc–dc converter. The converter is made to operate with two independent controllers—an input controller that performs power factor correction and regulates the dc bus and an output controller th...

The available shear correction factors have mainly been developed for homogeneous isotropic plates and/or assuming that no shear tractions are imposed on the top and bottom surfaces of the plate. In the present research, a more general case of a circular functionally graded plate subjected to non-uniform normal and shear tractions at the top and bottom surfaces is considered. These non-uniform ...

BACKGROUND "Probable active syphilis," is defined as seroreactivity in both non-treponemal and treponemal tests. A correction factor of 65%, namely the proportion of pregnant women reactive in one syphilis test type that were likely reactive in the second, was applied to reported syphilis seropositivity data reported to WHO for global estimates of syphilis during pregnancy. OBJECTIVES To iden...

The Variety Evaluation Project at SASRI involves conducting variety trials throughout the South African sugar industry. A general trend is that trial yields consistently exaggerate commercial yields obtained by growers under the same conditions. The objective of this study was to use historic variety trial and commercial yield data to evaluate the possibility of using correction factors and plo...

The implications of the many proper time amplitudes for the process Φ → K o + ¯ K o was discussed in a recent letter of B. Kayser and L. Stodolsky who predicted a small correction (∼ 5%) to the usually predicted phase oscillation frequency for forthcoming Φ factory experiments. Based on previous work (also using the many proper times formalism), we predicted a much larger correction factor ≈ 2....

We show that, in valence quark models, the relativistic corrections to the SU(6) relation for the contribution of the electric dipole moments of the quarks to the electric dipole moment of the neutron can be expressed as a multiplicative correction factor. The correction factor is evaluated in light cone wavefunction models, in the bag model, and in relativistic mean-eld models, and is found to...

Practical laser speckle contrast analysis systems face a problem of spatial averaging of speckles, due to the pixel size in the cameras used. Existing practice is to use a system factor in speckle contrast analysis to account for spatial averaging. The linearity of the system factor correction has not previously been confirmed. The problem of spatial averaging is illustrated using computer simu...
