TL;DR: A large-numerical-aperture aspherical singlet for three-dimensional (3-D) sensor applications is presented and this lens can be used to generate a homogenous irradiance on the target in a 3-D sensor, which is based on the principle of time of flight and uses an LED as light source.
Abstract: A design of a large-numerical-aperture aspherical singlet for three-dimensional (3-D) sensor applications is presented. This lens can be used to generate a homogenous irradiance on the target in a 3-D sensor, which is based on the principle of time of flight and uses an LED as light source. A numerical method was used in the design. The designed planoaspherical singlet has a numerical aperture of 0.67, low refractive index, and moderate surface shape for easy fabrication. The simulation results revealed that the irradiance deviation within 97% of the designed area is less than 5% and that the transmittance of the lens is greater than 90.5%. The results from a Lambertian source were compared with those from a point source.

TL;DR: In this paper, a study of the relationship between Gaussian plume models and wind tunnel models is presented, showing that the transition from building-affected dispersion levels to levels that were not significantly different from dispersion without a building was a function of the size of the building.

TL;DR: In this paper, an unbinned method based on the minimization of a likelihood ratio was applied to a subsample of data collected in 2008 (61 days live time) by searching for neutrinos during high state periods of the AGN light curve, the sensitivity to these sources was improved by about a factor of two with respect to a standard time-integrated point source search.
