In this paper a loop condition is defined which generalizes the cellularity criterion and applies to compacta with nontrivial shape. It is shown that if A", fc E", n > 5, are compacta which satisfy this loop condition and whose shape classes include a space having dimension in the trivial range with respect to n, then Sh(A") = Sh( Y) is equivalent to E" — X « E" — Y. An application is given to ...

Under stimulation of the receptive fields (RF) of neurons in the cat area 17 by flashing Y-like figures of different shape and orientation, the sensitivity to these figures was revealed in 72% of the studied cells, while 62% of units were sensitive to cross-like figures as well. Tuning to Y-like figures was typically selective to their shape and orientation, but in some cases it was invariant t...

Y-shape outlet structures are used to release the turbine water into a reservoir. Classical design often uses a Y-shape over a certain length and with a specific opening angle. Depending on the geometry, especially in turbine mode, significant undesired flow separations may occur at the bifurcation. Investigations were performed with physical model tests using ultrasonic profilers at 1 and 2 MH...

hydro-forming is a fabrication process that uses a fluid medium to form a piece by using high internal pressure. in tube hydro-forming, a tubular blank is placed between two dies, sealed and pressurized water injected, deforming the tube walls in the cavity form of the dies. exist several typical hydro-forming processes such as t- shapes, cross-shapes and y- shapes. successful hydro-forming dep...

Here we describe a baseline-based binary shape coding method in which arbitrarily shaped object is represented b y the traced 1-D data from baseline and turning point (TP). The shape coding is performed based on contour-based method in each separated shape. There are two coding modes in shape coding, i.e. intra and inter mode as in texture coding. In inter coding mode, object identification, gl...

Fruit shape is one of the most important quality factors in many domesticated plants. In this study, we used bulked segregate analysis (BSA) to identify two sequence-related amplified polymorphism (SRAP) markers linked to fruit shape in cucumber (Cucumis sativus L.). A segregating F2 population of 130 plants from a cross (B-2-2×Y-3) of B-2-2 with long fruit shape trait and Y-3 with round fruit ...

Platelets undergo shape change upon activation with agonists. During shape change, disc-shaped platelets turn into spiculated spheres with protruding filopodia. When agonist-induced cytosolic Ca(2+) increases were prevented using the cytosolic Ca(2+) chelator, 5, 5'-dimethyl-bis-(o-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid (5, 5'-dimethyl-BAPTA), platelets still underwent shape change, alt...

An Fe-16MndSi alloy exhibits a good one-way and a little two-way shape memories by the stress induced y + E martensitic transformation and its reversion on heating and cyclic thermal y 2 E transformations, respectively. An intrusion of small amount of a' martensite at the initial shape change is not found to deteriorate the one-way memory and rather enhance the two-way memory. The two Fe-Mn-C a...

We present an approach to function-based object recognition that reasons about the functionality of an object’s intuitive parts. We extend the popular “recognition b y parts” shape recognition framework to support “recognition by functional parts”, b y combining a set of functional primitives and their relations with a sel of abstract volumetric shape primitives and their relations. Previous ap...
