Vernier acuity is a form of hyperacuity in which the threshold offset between a test object and a reference object is smaller than the size of a foveal cone. Because the test and the reference objects usually have regular shapes (e.g. rectangular, triangular or circular), relatively few studies have addressed the role of shape information in determining hyperacuity thresholds. In this study, we...

The representation of the fuzzy set membership curve consisting trapezoidal, triangular, and linear shapes, has an important role in logic system. selection curve's shapes determines useable function affects output value. Previous studies generally used curves that had been employed predecessors or other did not explain reason for choosing a member curve. This condition became problem because t...

By using a two-dimensional phase-field-crystal (PFC) model, the liquid crystalline growth of the plastic triangular phase is simulated with emphasis on crystal shape and topological defect formation. The equilibrium shape of a plastic triangular crystal (PTC) grown from an isotropic phase is compared with that grown from a columnar or smectic-A (CSA) phase. While the shape of a PTC nucleus in t...

We present a robust method to find region-level correspondences between shapes, which are invariant to changes in geometry and applicable across multiple shape representations. We generate simplified shape graphs by jointly decomposing the shapes, and devise an adapted graph-matching technique, from which we infer correspondences between shape regions. The simplified shape graphs are designed t...

Results: The lengths of the spleens varied between 5 cm to 13 cm, with an average of 9.66 cm. Their breadth was between 3.5 and 9.5 cm. The average breadth was 6.22 cm. Their widths varied between 1.5 and 5.5 cm, with an average of 3.06 cm. The weights of the spleens showed great variations, ranging between 80 and 300 gm, with an average of 145.76 gm. Various shapes of the spleens were observed...

the star-mesh transformation allows the reduction of nodes in an electrical circuit. the gauss elimination method allows the reduction of unknowns in a system of linear equations . triangular decomposition can be used to find the inverse of a matrix. in this paper the coherence between these methods are discussed. it is shown that the gauss elimination method gives the same formula for star-mes...

Information from different sensors can be fused in various ways. It is often difficult to choose the most suitable method for solving a fusion problem. In a measurement situation, the measured signal is often corrupted by disturbances (noise, etc.). It is, therefore, meaningless to compare crisp values without the corresponding uncertainty intervals. This paper describes a toolbox including nin...

application of structures of flow pattern modification is one of the erosion control methods in bends. triangular vanes are among these structures which provide less scour depth compared to the other techniques such as spur dike. since little information on erosion and sedimentation pattern around triangular vanes are available, this study was conducted to study the effect of structure effectiv...
