Improved Modeling of Lunar Prospector Neutron Spectrometer Data: Implications for Hydrogen Content at Lunar Poles
Introduction: In recent years, a number of studies [1,2,3] have been published using data from the Lunar Prospector Neutron Spectrometer (LP-NS) to identify and quantify anomalously high hydrogen abundances near the poles of the Moon, which may be in the form of water ice. If water ice is indeed present at the lunar poles in high enough abundance, this could provide a critical resource for futu...
متن کاملFluxes of fast and epithermal neutrons from Lunar Prospector: evidence for water ice at the lunar poles.
Maps of epithermal- and fast-neutron fluxes measured by Lunar Prospector were used to search for deposits enriched in hydrogen at both lunar poles. Depressions in epithermal fluxes were observed close to permanently shaded areas at both poles. The peak depression at the North Pole is 4.6 percent below the average epithermal flux intensity at lower latitudes, and that at the South Pole is 3.0 pe...
متن کاملComparison of image restoration methods for lunar epithermal neutron emission mapping
Orbital measurements of neu tro ns by the Lunar Explori ng Neutron Detector (LEN D) onboard the Lunar Reconnaissance Orbiter are being used to quantify the spatial dis tribution of near surface hydrogen (H). In fe rred H concentration maps have low signal-to-noise (SN) and image restoration (IR) techniques are being studied to enhance results. A single-blind. two-phase study is described in whi...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
