Introduction Echo-planar imaging (EPI) is a group of fast data acquisition methods commonly used in fMRI studies. It acquires multiple image lines in k-space after a single excitation, which leads to a very short scan time. A well-known problem with EPI is that it is more sensitive to distortions due to the used encoding scheme. Source of distortion is inhomogeneity in the static B0 field that ...
Introduction: Geometric distortion, an important parameter in neurology and oncology. The current study aimed to design and construct a new three-dimensional (3D) phantom using a 3D printer in order to measure geometric distortion and its 3D reproducibility. Material and Methods: In this study, a new phantom ...
The sales and use of electric vehicles (EVs) have been growing in recent times Europe, with the hopes mitigating CO2 emissions enabling more sustainable transportation. Considering growth EV market, main goal this research is to shed light on what drives vehicles' satisfaction continuance intention. We collected data from 290 drivers Europe. Grounded task-technology fit model expectation-confir...
Fusion welding is widely used in heavy industries to join different parts together. But sometimes welding-induced distortions cause problems like misalignment during assembling and make costs to remove them. Thus it is imperative to predict and mitigate them to improve weldments quality and also reduce in fabrication costs. This study at first will introduce inherent deformation method for pred...
introduction: image distortion is one of the major problems of magnetic resonance imaging (mri) for use in 3dmri, velocity mri, fmri and radiotherapy treatment planning (rttp). it is widely known that the most obvious effect of the inhomogenity of the magnetic fields and the nonlinearity of the gradient is the geometric distortion of mr tomograms. in this study, the...
The so called the traditions of distortion, the ambiguity in the history of codification of the Holy Qurān, the traditions likening the major events in the Islamic nation to the events of past nations and also the fact that the names of the infallible Imams are not mentioned in the Holy Qurān are the most important reasons which lead in the claim that Qurān might be distorted. Out of these reas...
Distributed database directory refresh strategies, commonly recommended for the X.500 standard, are defined and analytically modeled for variations on push/pull and total/differential under idealistic asynchronous control conditions. The models are implemented in a HyperCard-based tool called DirMod (for “directory model”). Experimental test results show important elapsed time performance trade...
