Abstract— An active approach to sensing can provide the focused measurement capability over a wide field of view which allows correctly formulated Simultaneous Localisation and Map-Building (SLAM) to be implemented with vision, permitting repeatable long-term localisation using only naturally occurring, automatically-detected features. In this paper we present the first example of a general sys...

Introduction: Until now, many models have been presented for optical study of the human eye. In recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. Material and Methods: In this article, some of these models are considered. They incl...

abstract heavy metals are the most important components of environment pollution. soil contaminated by industrial and mining activities of these elements into the soil-plant-human cycle and accumulate in the human or animal body tissue to reach the levels of toxic for animals and humans. for this purpose, a broad sampling of soil, plant and sheep liver were taken and the amount of pb were teste...

A direct method called fixation is introduced for solving the general motion vision problem, arbitrary motion relative to an arbitrary environment. This method results in a linear constraint equation which explicitly expresses the rotational velocity in terms of the translational velocity. The combination of this constraint equation with the Brightness-Change Constraint Equation solves the gene...

in this article, creative and lateral thinking is used to elaborate certain artwork, which can be seen from all sides, but maintain a unified meaning and value. the significance of this subject leads toward research with emphasis on horizontality and with the aim of protecting and publicizing this concept. this is done through decoding the principles and symbols of islamic arts in order to arri...
