A fast and perceptively plausible method for rendering acoustic scenarios with moving sources and moving listeners is presented. The method is principally suited for application in dynamic and interactive evaluation environments (e.g., for hearing aid development), psycho-physics with adaptively changing the spatial configuration, or simulation and computer games. The simulation distinguishes b...

background although iranian women increasingly attend hospitals for childbirth, no information is available on programs and practices related to infection control in labor and delivery units. conclusions the results of this study revealed a need for development of appropriate policies and protocols for infection control practices in labor and delivery units and also midwives training on clean d...

The design requirements for current heavy-particle accelerators operated within a hospital to deliver radiation therapy must satisfy both clinical and research needs. Advances in dedicated beam delivery systems for clinical utilization and biological studies add requirements that previous accelerators did not have. Eight years experience using the Loma Linda University proton facility has empha...

The next-generation conference room will support an increasingly distributed workforce. As distributed meetings become the norm, collaboration tools used in conference rooms must be designed to seamlessly integrate remote participants in formal meetings and ad-hoc gatherings. In the Meeting Central project at Sun Labs, we have shown that simple tools can significantly increase meeting effective...

In this paper we start from a set of images obtained by the robot that is moving around in an environment. We present a method to automatically group the images into groups that correspond to convex subspaces in the environment which are related to the human concept of rooms. Pairwise similarities between the images are computed using local features extracted from the images and geometric const...

abstract background assuring safety and survival of blood in vitro depends on anti-coagulation substances, blood bag characteristics, storage conditions, and transport of blood. besides, careful selection and screening of donors as well as blood tests can minimize the transmission risk of blood-transmissible pathogens and optimize blood health. the aim of this study was to assay the level of kn...
