The PROPELLER sequence is clinically used for T2 and DW imaging and can be motion corrected. Parallel imaging techniques have been used in axial PROPELLER imaging to effectively widen the blade, thus reducing motion artifacts and improving general image quality. However, parallel imaging is not suitable for all image orientations with all available coils (e.g. PROPELLER spine imaging). We propo...

Note: This is a translation of the original article " Influenţa factorilor subiectivi asupra percepţiei calităţii vieţii " , published in Romanian the journal " Calitatea vieţii " (translated title: 1. Introduction If, in order to evaluate the quality of life of a collectivity or social group, we employ measures of the quality of life of its individual members, this psycho-individual frame may ...

One of the emerging research areas in the strategic orientation is how to transfer different orientations from the commercial sector to the non-profit sector. Therefore, the objective of this study is to determine the mediating effect of Learning Orientation on the Market Orientation, Social Entrepreneurial Orientation, and Organizational Performance in the non-profit sector. The data from more...

for a graph g, let d(g) be the set of all strong orientations of g. the orientationnumber of g is min {d(d) |d belongs to d(g)}, where d(d) denotes the diameterof the digraph d. in this paper, we determine the orientation number for some subgraphs of complete bipartite graphs.

Over the past five years, the School of Applied Vision Sciences at the University of Sydney has used orientation activities to improve the quality of the students’ online learning experience while they are located remotely from the campus undertaking professional practice placements. During 2004 and 2005, students were introduced to Salmon’s five-stage model of online learning and teaching in t...

We study a class of Labelled Oriented Graph (LOG) group where the underlying graph is a tadpole graph. We show that such a group is the natural HNN extension of a cyclically presented group and investigate the relationship between the LOG group and the cyclically presented group. We relate the second homotopy groups of their presentations and show that hyperbolicity of the cyclically presented ...

By thermal evaporation of pure ZnO powders, high-density vertical-aligned ZnO nanorod arrays with diameter ranged in 80–250 nm were successfully synthesized on Si substrates covered with ZnO seed layers. It was revealed that the morphology, orientation, crystal, and optical quality of the ZnO nanorod arrays highly depend on the crystal quality of ZnO seed layers, which was confirmed by the char...

Fractal image compression exploits the self-similarity of an image to achieve the purpose of compression. In the standard algorithm, eight Dihedral transformations are applied on domain blocks to increase the codebook size, and therefore, the quality of reconstructed image can be improved. However, such mechanism consumes approximately eight times of the encoding time. On the other hand, if no ...
