One of the basic difficulties with interactive walkthroughs is the high quality rendering of object surfaces with non-diffuse light scattering characteristics. Since full ray tracing at interactive rates is usually impossible, we render a precomputed global illumination solution using graphics hardware and use remaining computational power to correct the appearance of non-diffuse objects on-the...

Corrective and conditioning exercises accomplish two entirely different purposes, yet they are frequently confused. Corrective exercises are given solely for the purpose of eradicating a postural defect and thereby increasing efficiency, while conditioning exercises aim at the increase of strength and endurance. No correction is necessarily accomplished but any defects present may be either imp...

Since the writing of A. C. Pigou (1932), taxes have been emphasized as a means of control of activities that generate harm, especially in the domain of pollution, yet their use is in fact limited (Robert N. Stavins 2003). In contrast, liability has great importance in reducing harm. Much of the vast terrain of accidents—from oil spills, to crane mishaps, to car collisions—is subject to liabilit...

Learning about Recycling and Reuse through Pre-School Games S.M. Shobeyri, Ph.D. H. Meybodi A. Saraadipoor S. Rashidi Environmental education is the most fundamental approach to environmental protection and can begin from the pre-school level and through the use of games. To show the effectiveness of this approach, a random sample of 30 preschoolers of ages 5 and 6 was se...

Using event-related brain potentials, the time course of error detection and correction was studied in healthy human subjects. A feedforward model of error correction was used to predict the timing properties of the error and corrective movements. Analysis of the multichannel recordings focused on (1) the error-related negativity (ERN) seen immediately after errors in response- and stimulus-loc...

BACKGROUND Disfiguring dermatoses may have a significant impact on patients' quality of life, namely on their relationship with others, self image, and self esteem. Some previous studies have suggested that corrective foundation can improve the quality of life (QOL) of patients with facial dermatoses; in particular, in patients with acne vulgaris or pigmentary disorders. OBJECTIVE The aim of ...
