Exploring the significance of geo-tagged information of a satellite image and associated shadow information in the image to enable man-made infrastructure dimensional characterization, in this paper a novel approach has been developed to estimate the height of a man-made structure accurately. Our proposed method applies shadow detection and shadow feature along with geo-tagged information retri...

HARD, SOFT, AND STICKY SPHERES FOR DYNAMICAL STUDIES OF DISORDERED COLLOIDAL PACKINGS Matthew Daniel Gratale Arjun G. Yodh This thesis describes experiments which explore the role of interparticle interactions as a means to alter, and control, the properties of dense colloidal packings. The first set of experiments studied phonon modes in two-dimensional colloidal crystals composed of soft micr...

the light in modern concept has accompanied by theater as one of the formative elements of showing art from the first days of theater emergence and todays various functions have been defined for that and it has been and is being used for different purpose. on the other hand, the light is always with shadow on the scene and lack of light causes to darkness on the scene. so, the light, shadow, an...

Figure 1: Comparison between trapezoidal shadow maps (TSMs) and subdivided shadow maps. a) TSM with 1K×1K shadow map, b) TSM with 4K×4K shadow map, and c) 1K×1K subdivided shadow map. This configuration with a small angle between the light and view directions is difficult for prior methods. Even with the largest shadow map that can be allocated on current hardware, TSMs are not able to match th...

Accurate masking of cloud and cloud shadow is a prerequisite for reliable mapping of land surface attributes. Cloud contamination is particularly a problem for land cover change analysis, because unflagged clouds may be mapped as false changes, and the level of such false changes can be comparable to or many times more than that of actual changes, even for images with small percentages of cloud...

View synchronous communication (VSC) is a paradigm initially proposed by the Isis system, that is well suited to implement fault-tolerant services based on replication. VSC can be seen as an adequate low level semantics on which ordered multicasts and uniform multi-casts can easily be implemented. This paper presents the speciic problems related to the implementation of VSC in a large scale net...

arid and desert lands in terms of specific environmental characteristics such as low annual precipitation,sequential droughts, huge drop in ground water levels or the like, have always faced strict limitations in waterresources. in the shadow of these characteristics and many other factors, water price index (wpi) is significantlyaffected. this study set out with the aim of identifying and dete...

We have studied the shadows of a Schwarzschild black hole under special polar gravitational perturbation, which is particular solution Einstein equations expanded up to first order. It shown that shadow changes periodically with time and change depends on Legendre polynomial order parameter l frequency {\sigma} wave. For odd polynomial, center oscillates along direction vertical equatorial plan...
