Registration of multiple 3D ultrasound sectors in order to provide an extended field of view is important for the appreciation of larger anatomical structures at high spatial and temporal resolution. In this paper, we present a method for fully automatic spatio-temporal registration between two partially overlapping 3D ultrasound sequences. The temporal alignment is solved by aligning the norma...

Rigid plate-like particles displaying interfacial slip can attain a constant orientation in shear flow when the length is sufficiently large. But actual thin such as single-layer graphene are prone to bending deformations exposed stress. To study effect of deformation on particle's stable orientation, we develop two-dimensional fluid-structure interaction model. We find that (i) alignment occur...

OBJECTIVE Preoperative magnetic resonance imaging (MRI), functional MRI, diffusion tensor MRI, magnetic resonance spectroscopy, and positron-emission tomographic scans may be aligned to intraoperative MRI to enhance visualization and navigation during image-guided neurosurgery. However, several effects (both machine- and patient-induced distortions) lead to significant geometric distortion of i...

Reconstruction of scene geometry and semantics are important problems in vision, and increasingly brought together. The state of the art in Structure from Motion and Multi View Stereo (SfM+MVS) can already create accurate, dense reconstructions of scenes. Systems such as CMPMVS [2] are freely available and produce impressive results automatically. However, when assumptions break down or there i...

beside developing strategies, success of organizations depends on alignment of strategies. one of the important functional areas in which companies develop strategies is operation. alignment of operation strategies is called horizontal alignment. the aim of this article is to present a model for alignment of operation strategies. to this end, an original algorithm has been presented by which ho...

this study proposes a new linear approximation for solving the dynamic response equations of a rocking rigid block. linearization assumptions which have already been used by hounser and other researchers cannot be valid for all rocking blocks with various slenderness ratios and dimensions; hence, developing new methods which can result in better approximation of governing equations while keepin...

preset study is conducted to evaluate strategic alignment between business and it in the view of organizational managers. present study has used luftman’s model on strategic alignment maturity and gartlen & shenks’ factors to promote alignment in order to evaluate alignment. research statistical population consists of managers at high education planning and research institute. no sampling is co...

The quantification of knee alignment is a routine part of orthopaedic practice and is important for monitoring disease progression, planning interventional strategies, and follow-up of patients. Currently available technologies such as radiographic measurements have a number of drawbacks. The aim of this study was to validate a potentially improved technique for measuring knee alignment under d...

Abstract We investigate, both analytically and numerically, the quantum dynamics of a planar (2D) rigid rotor subject to suddenly switched-on or switched-off concurrent orienting aligning interactions. find that time-evolution post-switch populations as well expectation values orientation alignment reflects spectral properties eigensurface topology pendulum eigenproblem established in our earli...
