Active Perception (Active Vision specifically) is defined as a study of Modeling and Control strategies for perception. By modeling we mean models of sensors, processing modules and their interac-tion. We distinguish local models from global models by their extent of application in space and time

strategy for studies of gravitational lensing effects with a LMT rather consists in first surveying a sky area as deep and as wide as possible for interesting targets (cf. quasar candidates using color or variability criteria) and then select gravitational lens candidates among them. The extent

Abstract: We studied a two-dimensional square-lattice photonic crystal with all-angle negative refraction at its first band. Using this photonic crystal, we designed and fabricated a flat lens functioning as a cylindrical lens by increasing the vertical dimension of the photonic crystal

*Presently, developmental biology has almost replaced the term embryology. But, in terms of history and concept, I do not think both are completely synonymous. In the present article, I mostly use “embryology”, without a strict definition, be-cause what I am often concerned with are historical issues before developmental biology came to be known as such.

Abstract: The objectives of this work are to study Laser Engineered Net Shaping (LENS

We present a longitudinal-differential (LD) phase distribution near the focus of a high numerical aperture (NA=0.9) aplanatic lens illuminated with a linearly polarized monochromatic plane wave. The Richards and Wolf method is used to compute field distributions. The LD phase map is obtained

Traditional activities change in surprising ways when computermediated communication becomes a component of the activity system. In this descriptive study, we leverage two perspectives on social activity to understand the experiences of individuals who became active collaborators in Wikipedia, a

Applying a geographic lens to mutual fund performance, this study finds that fund managers earn substantial abnormal returns in nearby investments. These returns are particularly strong among funds that are small and old, focus on few holdings, and operate out of remote areas. Furthermore, we find

The results of a nine month field study show that although there are several challenges to overcome, mobile recommender systems have the potential to provide value
