Extracting useful and robust feature points from a cylinder image for 3D pose determination is a relatively difficult task, since there are no feature points or lines on the cylinder. In this study, a key vector from a cylinder image is found to yield a transformation. The cylinder is then "reprojected" from the original image to obtain a new image using the transformation. The new image reveal...

The quality of Text-to-Visual-Speech synthesis is judged by how well it matches the visual perception of speech articulators with acoustic speech perception. Concurrently, di erent viewers often prefer di erent head models for subjective reasons. Traditional facial animation approach tied the parameterization of animation directly to the model. Switching the head model is di cult because a leng...

The exact solution is found for the Stefan problem of inwards freezing of a nonhomogeneous cylinder whose specific heat and latent heat depend upon the inverse square of the radial distance. The freezing time for the corresponding annular cylinder is found exactly. The validity of the pseudo-steady-state approximation for the solvable cylinder problem is verified explicitly. It is argued that t...

(Belfer) holds nearly 20,000 cylinder recordings produced during the 'cylinder era' of 1895-1929. Many cylinders have become deteriorated over the past one hundred years and cannot be played without suffering serious physical damage inflicted by the sharp styli (needles) of traditional mechanical playback machines. In some cases, even one pass of a stylus may irrevocably damage a cylinder. In r...

from the perspective of rural development experts, organize small enterprise, s (ses), is a strategy for empowering villagers, especially poor women's and rural women heads of household. hundreds of ses by women heads of household has been launched in iran. this research has been done to evaluate the effects of ses on women's economic empowerment of rural women heads of household in t...

knowledge on animal requirement, available forage and its quality is fundamental for successful livestock and range management. since sheep is dominant grazing animal of rangelands in iran and there are over 27 sheep breeds and each breed has special body size, physiological condition and consequently different daily nutrition requirement, animal unit should be determinated for dominant breed o...

We analyze recent experiments that show that a cylinder can be suspended in a stable position by placing it on a vertically moving belt that is covered by a thin layer of very viscous oil. The weight of the cylinder is supported by viscous forces in the fluid layer, and the cylinder rotates with respect to its axis in the direction of the belt motion. We propose a simple model for stable suspen...

write: A pump has been constructed as a possible solution to a problem posed by one of us (D.W.)-namely, to produce a device which would wash out the bladder after prostatectomy vwithout breaking the closed drainage system (which could result ia an infection) and which could be used by relatively unskilled staff. The pump with its associated valves is composed of only two parts-a piston and a c...
