DEFINITION Definitions are given in an attempt to identify phenomena and to delineate examples from non-examples. Expertise is consensually defined as elite, peak, or exceptionally high levels of performance on a particular task or within a given domain. One who achieves this status is called an expert or some related term, such as virtuoso, master, maven, prodigy, or genius. These terms are me...

In this paper, a new approach is presented for improving image quality. It provides a new outlook on how to apply the enhancment methods on images. Image enhancement techniques may deal with the  illumination, resolution, or distribution of pixels values. Issues such as the illumination of the scene and reflectance of objects affect on image captures. Generally, the pixels value of an image is ...

Pier is the second generation of an industrial strength content management and application framework. Pier is written with objects from top to bottom and it is easily customized to accommodate new requirements. Pier is based on Magritte, a powerful meta-description framework. Pier has proven to be very powerful in the combination with Seaside, to enable easy composition and configuration of int...

background:       lymphedema is a common complication for breast cancer therapy. patients with lymphedema may experience pain and body image issues. this study investigates the effect of combined decongestive therapy and pneumatic compression pump on body image in patients with lymphedema secondary to breast cancer treatment. methods:       42 women with breast cancer related lymphedema partici...

speckle is a granular disturbance in coherent images such as synthetic aperture radar (sar) images, modeled as a multiplicative noise. this noise degrades the sar image and complicates the image exploitation using automated image analysis techniques. several approaches have been developed to reduce the effect of speckle noise. recently, the application of compressed sensing (cs) is explored in ...

A system of orthonormal functions representing the eigenmodes of an optical resonator with perfectly spherical mirror surfaces has been described in the literature. In real experiments, however, the wave front of the passing beam will be deformed by surface irregularities or index inhomogeneities inside components traversed by the beam. We describe quantitatively the relative power transferred ...

Plutarch and Heraclitus believed a certain passage in the 20th book of the Odyssey ("Theoclymenus's prophecy") to be a poetic description of a total solar eclipse. In the late 1920s, Schoch and Neugebauer computed that the solar eclipse of 16 April 1178 B.C.E. was total over the Ionian Islands and was the only suitable eclipse in more than a century to agree with classical estimates of the deca...

as the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. this processing comprises two fundamental and critical steps towar...

In recognition of the fact that many systems contain both continuous and discrete aspects, considerable study has been devoted recently to "hybrid systems." The formulation of equations of motion for hybrid systems in explicit form, including the condition/event rules and the description of the continuous dynamics for every possible mode, is in many cases a formidable task, and there is a clear...
