background imaging plays a critical role not only in the detection, but also in the characterization of lung masses as benign or malignant. objectives to determine the diagnostic accuracy of dynamic magnetic resonance imaging (mri) in the differential diagnosis of benign and malignant lung masses. patients and methods ninety-four masses were included in this prospective study. five dynamic seri...

abstractbackground: delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. the aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field.   methods: the software was written based on local enhancement of the pixel values in image mat...

The North Tabriz Fault is seismologically an active fault with current right lateral strike-slip movements. Restricted mafic to intermediate Late Cretaceous igneous rocks are exposed along the North Tabriz Fault. Whole rock samples and clinopyroxene phenocrysts geochemistry were studied in order to characterize the petrogenesis of these mafic rocks and their possible relation to an oceanic crus...

In this paper, an approach is proposed for accurate locating of single phase faults in transmission lines using voltage signals measured at one-end. In this method, harmonic components of the voltage signals are extracted through Discrete Fourier Transform (DFT) and are normalized by a transformation. The proposed fault locator, which is designed based on Random Forests (RF) algorithm, is train...

Quantifying and characterising atomic defects in nanocrystals is difficult and low-throughput using the existing methods such as high resolution transmission electron microscopy (HRTEM). In this article, using a defocused wide-field optical imaging technique, we demonstrate that a single ultrahigh-piezoelectric ZnO nanorod contains a single defect site. We model the observed dipole-emission pat...

Originality and Novel aspects of this paper (for reviewer’s benefit only, this will be removed in the final manuscript) This paper describes the use of magnetic current imaging to isolate a plane-to-plane short in a printed circuit board. The sensor used for the magnetic current imaging is a SQUID. This technique is realtively new, but the real novel application here is the use of the tool for ...

Reliability of software counts on its fault-prone modules. This means that the less software consists of fault-prone units the more we may trust it. Therefore, if we are able to predict the number of fault-prone modules of software, it will be possible to judge the software reliability. In predicting software fault-prone modules, one of the contributing features is software metric by which one ...
