AIM To analyze how various implants placement variables affect sacroiliac (SI) joint range of motion. METHODS An experimentally validated finite element model of the lumbar spine and pelvis was used to simulate a fusion of the SI joint using various placement configurations of triangular implants (iFuse Implant System®). Placement configurations were varied by changing implant orientation, su...

Quantitative assessment of myofiber disarray associated with diseases such as familial hypertrophic cardiomyopathy (FHC) can be performed by estimating local angular deviation of fiber orientation in histologic sections. The large number of measurements required to estimate angular deviation prohibits manual measurement. We describe methods for automated measurement of local orientation and ang...

objective: the objective of this study was to determine the relationship between religious orientation (intrinsic–external) and cognitive distortions. methods: general design of this study considered as a descriptive and correlational method. universal population in this research consist all students of the urmia azad university, which were studying during 2012 and 2013 (n = 250). all responden...

corporate support for entrepreneurship is the most important element for the development of corporate entrepreneurship and is considered as one of the main corporate entrepreneurial antecedents. it involves trust in corporate staff and training them for promoting recognition of opportunities, exploring new and valuable resources, innovative productions and profit-making processes. corporate sup...

Flow past a square cylinder placed at an angle to the incoming flow is experimentally investigated using particle image velocimetry, hot wire anemometry, and flow visualization. The Reynolds number based on cylinder size and the average incoming velocity is set equal to 410. Data for four cylinder orientations =0, 22.5, 30, and 45° and two aspect ratios AR=16 and 28 are reported. Results are pr...

100 Orientation di usions P. Perona Abstract|Di usions are useful for image processing and computer vision because they provide a convenient way of smoothing noisy data, of analyzing images at multiple scales, and of enhancing discontinuities. A number of di usions of image brightness have been de ned and studied so far; they may be applied to scalar and vector-valued quantities that are natura...

The present research assessed racial differences in the associations among controlled orientation, injunctive norms, and increased drinking by White and Asian American college students. Previous research has noted racial differences in drinking, but reasons have not been considered in the context of individual differences in self-determination or responses to social influences. The authors eval...

While research on the spatial representation of number has provided substantial evidence for a horizontally oriented mental number line, recent studies suggest vertical organization as well. Directly comparing the relative strength of horizontal and vertical organization, however, we found no evidence of spontaneous vertical orientation (upward or downward), and horizontal trumped vertical when...

For many years we have had digital photogrammetric systems available that can perform automatic interior and relative orientation of aerial photographs. Developments in absolute and exterior orientation are not so robust because the problem is significantly more difficult. The reason for the increase in difficulty is that there is no easy way to create the master image or target patch which rep...

In this paper we initialize the study of independent domination in directed graphs. We show that an independent dominating set of an orientation of a graph is also an independent dominating set of the underlying graph, but that the converse is not true in general. We then prove existence and uniqueness theorems for several classes of digraphs including orientations of complete graphs, paths, tr...
