OBJECTIVE To explore the relationship between the risk factors for the development of venous ulcers and the indicators of tissue integrity from the Nursing Outcomes Classification. METHODOLOGY A cross-sectional study conducted in 2013 in a university hospital in Natal/RN (Brazil). Fifty individuals selected by consecutive sampling participated in an interview and physical examination. RESUL...

Regional two-dimensional (2D) echocardiographic amplitude patterns, or image texture, may be of diagnostic importance. Echocardiographic image texture is due in part to acoustic speckle, a complex pattern of interference of reflections from many small scatterers in tissue. The regional speckle pattern appears to be altered in several disorders associated with abnormalities in myocardial structu...

This paper describes a novel rendering technique for the special relativistic visualization of the apparent geometry of fast moving objects. This method is based on the relativistic aberration of light and makes use of texture mapping. Interactive frame rates are possible, since texture mapping is supported by modern graphics hardware. Unlike the well-known relativistic polygon rendering approa...

In this paper, we present a method that integrates cues from shading, shadow and specular reflections for estimating directional illumination in a textured scene. Texture poses a problem for lighting estimation, since texture edges can be mistaken for changes in illumination condition, and unknown variations in albedo make reflectance model fitting inpractical. Unlike previous works which all a...

today,  iran is faced with a considerable amount of old and timeworn textures. based on  the estimates of  the ministry of  housing and urban development, there are more than 50,000 hectares of urban  old texture in iran, that  due to the lack of credits and understanding of quality and characteristics of such regions, the government has faced with several problems in planning and defusing the ...

Visual clues as to the physical substance of manufactured objects can be misleading. For example, a plastic ring can appear to be made of gold. However, we can avoid misidentifying an object׳s substance by comparing visual and tactile information. As compared to the spatial properties of an object (e.g., orientation), however, little information regarding physical object properties (material pr...

The haptic sensations one feels when interacting with physical objects create a rich and varied impression of the objects, allowing one to gather information about texture, shape, compressibility, and other physical characteristics. The human sense of touch excels at sensing and interpreting these haptic cues, even when the object is felt through an intermediary tool instead of directly with a ...
