The ability to acquire 3-D information about passable free spaces and objects around them is essential for mobile robot navigation in unknown scene. We present a new method of selective reconstruction of a 3-D scene around free spaces with an active stereo vision system. Our method is based on the following observation: The larger and deeper passable free spaces may exist in the direction to wh...
Background and aims: Color vision is one of the most important capabilities of the visual system. color vision impairment in many jobs, lead to reduced productivity, increased reaction time and workers' decision-making in confronting with of hazardous situations and as a result, it can lead to occupational accidents. This study was carried out to investigate occupational exposure to BTEX solven...
Most cataract surgery patients desire to not only enjoy excellent nonspectacle corrected distant vision, but also non-corrected near vision with glasses independence in this modern era. The implantation of accommodative IOLs may achieve this vision after cataract surgery according to the literature [2]. However, the price of the accommodative IOLs is about ten times more than the standard IOL. ...
we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...
PURPOSE To evaluate the distance, intermediate and near visual acuity of patients with bilateral cataract operated on both eyes corrected for distance in one eye and for near in the fellow eye, as well as, their stereo acuity and their general satisfaction. SETTINGS Hospital de Olhos de São Paulo and Complexo Hospitalar Padre Bento - Guarulhos - São Paulo - Brazil. METHODS This is a prospec...
Nearly all underwater vehicles and surface ships today use sonar and vision for imaging and navigation. However, sonar and vision systems face various limitations, e.g., sonar blind zones, dark or murky environments, etc. Evolved over millions of years, fish use the lateral line, a distributed linear array of flow sensing organs, for underwater hydrodynamic imaging and information extraction. W...
