Postero-anterior films of the chest frequently fall to reveal satisfactory evidence of the pathology which may be present. To obtain a better perspective of the lung lesions, it is often necessary to resort to lordotic and oblique films. The value of such positional roentgenograms, however, has been limited because the importance of definite methods of standardizing these films has not received...

Spin-wave instability for parallel pumping is studied theoretically. The spin-wave instability threshold is calculated in ferromagnetic thin films under oblique field which has an oblique angle to the film plane. The butterfly curve of the threshold usually has a cusp at a certain value of the static external field. While the static field value of the cusp point varies as the oblique angle chan...

This article describes a new system for induction of oblique decision trees. This system, OC1, combines deterministic hill-climbing with two forms of randomization to nd a good oblique split (in the form of a hyperplane) at each node of a decision tree. Oblique decision tree methods are tuned especially for domains in which the attributes are numeric, although they can be adapted to symbolic or...

Body tilt effects on the visual reproduction of orientations and the Class 2 oblique effect (E. A. Essock, 1980) were examined. Body tilts indicate whether the oblique effect (i.e., lower performance in oblique orientations than in vertical-horizontal orientations) is defined in an egocentric or a gravitational reference frame. Results showed that the oblique effect observed in upright posture ...

In recent years, oblique aerial images of urban regions have become increasingly popular for 3D city modeling, texturing, and various cadastral applications. In contrast to images taken vertically to the ground, they provide information on building heights, appearance of facades, and terrain elevation. Despite their widespread availability for many cities, the processing pipeline for oblique im...

The present research addresses the question of the "oblique effect" (better discrimination of the vertical orientation than of an oblique orientation) in manual haptic perception of orientations (without visual control) by 5-month-old infants. A familiarization/reaction to novelty procedure was used. The results revealed the occurrence of a haptic oblique effect. These findings are similar to t...

Oblique transition can be triggered by introducing componentwise optimal perturbations into a plane Couette flow. It is shown that in the middle stage of transition, oblique vortices are generated again through transient spanwise velocity energy growth presence developed streamwise streaks. In following stage, independent kinetic energies cross-streamwise velocities intensified due to nonlinear...

Abstract This study presents a design scheme for multi-module connected floating dock, comprising two configurations the lower body: transverse and longitudinal floats. An articulated connection between modules is also included. The hydrodynamic performance of dock with these compared analyzed by taking South China Sea as an example. Frequency time-domain analysis methods are employed, consider...

Previous research indicated that 4-month-old infants perceive continuity of objects moving on horizontal trajectories but appear to have difficulty processing occlusion events involving oblique trajectories. However, because perception of continuity of vertical trajectories has not been tested, it is uncertain whether this indicates a specific deficit for oblique trajectories or a specific adva...

PURPOSE To develop and test a method for automatically calculating the in-plane rotation for doubly-oblique slice geometry in order to minimize wrap artifacts for a given FOV. MATERIALS AND METHODS The equations for in-plane rotation were formulated for doubly-oblique imaging of a cylindrical body with elliptical cross-section. Based on this formulation, automatic in-plane rotation was implem...
