The primary scientific objective of this research is to develop GPS sounding techniques for ground based atmospheric refractivity sensing. Atmospheric profiling with GPS from space has been demonstrated (e.g. Rocken et al., 1997). Ground based receivers have been used to determine integrated atmospheric water vapor above a site, but profiling techniques with ground-based GPS observations are st...

To move one step forward toward a Galactic distribution of planets, we present the first planet sensitivity analysis for microlensing events with simultaneous observations from space and the ground. We present this analysis for two such events, OGLE-2014-BLG-0939 and OGLE-2014-BLG-0124, which both show substantial planet sensitivity even though neither of them reached high magnification. This s...

-Data and observations from 1995, 1996 and 1997 wet season surveys of natural and artificial tree holes suggest that hole morphology and size are important predictors of the distribution and abundance of Microvelia cavicola Polhemus. The bugs occurred in 42% of the natural holes sampled and <3% of artificial hole censuses. The distribution of M. cavicola was not associated with holes in particu...

In the present study, ten steel-moment resisting frames (SMRFs) having different numbers of stories ranging from 3 to 20 stories and fundamental periods of vibration ranging from 0.3 to 3.0 second were optimized subjected to a set of earthquake ground motions using the concept of uniform damage distribution along the height of the structures. Based on the step-by-step optimization algorithm dev...

Cloud base height (CBH) is crucial for parameterizing the cloud vertical structure (CVS), but knowledge concerning temporal and spatial distribution of CBH still poor owing to lack large-scale continuous observations. Taking advantage high resolution observations from Advanced Himawari Imager (AHI) on board geostationary Himawari-8 satellite, this study investigated climatology by applying a no...
