Civil aviation operators have expressed an increased interest in conducting night operations with night vision imaging systems. The development of special operational concepts, hardware requirements, training requirements, and regulatory change and oversight is necessary to control for the known performance constraints associated with these devices. In 2001, the Aerospace Medical Association in...

Abstract In tropical areas, since the day length (DL) is shorter than critical DL for chrysanthemum (Dendranthema x grandiflorum Kitam.), flowers before reaching required stem (SL) cut flower. Two experiments were conducted with aim of determining vegetative growth genotype; to attain a SL and promote using night break (NB) red light spray type chrysanthemum. first experiment, was extended by o...

We present results of our intra-night optical flux monitoring observations of S5 0716+714 done simultaneously in g, RC and IC filters. The observations were done using Multicolor Imaging Telescopes for Survey and Monstrous Explosions (MITSuME) instrument on the 50 cm telescope at the Okayama Astrophysical Observatory over 30 nights between 11 March 2008 and 8 May 2008. Of these 30 nights, 22 ni...
