Abstract This lecture introduces various kinds of spin rotating devices used in present particle accelerators. They include Siberian Snakes for polarization preservation and rotators creating a specific orientation experimental locations. Following the analysis rotation different types magnets, approaches designing are discussed. Considerations appropriate design choices dependence on beam ener...

ophionyssus natricis is a purely blood sucking parasite of snakes and of worldwide distribution. infected snakes often exhibit lethargy, pruritus, crusting dermatitis,and behavioral changes. ophionyssus natricis can also attack humans, causing popular vesiculo-bullous eruption of the skin. a 29 years old man working in zoo,sari, mazandaran, iran, presented itchy papullar eruption of the skin. h...

Delineation of irregular shaped objects can be realized using active contours, called snakes[l]. However, the minimization of the potential energy pushes the control points toward the lowest potential energy regions, so most of the control points lie in those regions and a few, or even no control points lie in other parts of the contours, as shown in the Fig.1. We propose an Equidistant Snake t...

The extent, sequence, synchrony and correlates of diel displacements by animals can provide powerful insights into the ecological and social factors that shape an organism’s day-to-day activities, but detailed data on spatial ecology are available for very few tropical taxa. Radiotelemetricmonitoring of 25 slatey-grey snakes (Stegonotus cucullatus) on a floodplain in the Australian wet-dry trop...

Active contour models have been widely applied to image segmentation and analysis. It has been successfully used in contour detection for object recognition, computer vision, computer graphics, and biomedical image processing such as X-ray, MRI and Ultrasound images. The energy-minimizing active contour models or snakes were developed by Kass, Witkin and Terzopoulos in 1987. Snakes are curves d...
