Approximate soft shadows on arbitrary surfaces using Penumbra wedges

Shadow generation has been subject to serious investigation in computer graphics, and many clever algorithms have been suggested. However, previous algorithms cannot render high quality soft shadows onto arbitrary, animated objects in real time. Pursuing this goal, we present a new soft shadow algorithm that extends the standard shadow volume algorithm by replacing each shadow quadrilateral with a

The Rudder of the Church : A Study of the Theory of Canon Law in the Pedalion

This thesis is a study of the theology of canon law in the Pedalion. The Pedalion (Πηδάλιον: ”rudder”) is a famous Greek Orthodox collection of canon law. It was printed in Leipzig 1800 by permission of the Holy Synod of the Ecumenical Patriarchate. St. Nikodemos Hagioreites and Agapios Leonardos were the authors. What is the theoretical foundation of canon law according to the Pedalion? How is th

RS(23,17) decoder for UWB

This paper presents the Reed-Solomon (RS) decoder for multiband OFDM(MB-OFDM) ultra-wideband(UWB). In UWB system, RS (23,17) code is adopted. To achieve high throughput and small area, two iterative Modified Euclidean (ME) blocks are proposed to work by turns in this paper. The architectures of syndrome block, ME block, Chien search block, Forney block are presented later in detail. At last, this

MRI Findings in Spinal MRI of 306 Children with Scoliosis. A Comprehensive Retrospective Analysis.

The aim of this study was to analyze the MRI findings and assess the prevalence of different associated structural abnormalities in children with scoliosis and to determine if the age of onset is a possible indicator of intraspinal pathology. This is a retrospective analysis of 663 consecutive MR examinations (319 patients). Thirteen patients with known intraspinal tumors were excluded and a total
