Heavy rain deteriorates the video quality of outdoor imaging equipments. In order to improve video clearness, image-based and sensor-based methods are adopted for rain detection. In earlier literature, image-based detection methods fall into spatio-based and temporal-based categories. In this paper, we propose a new image-based method by exploring spatio-temporal united constraints in a Bayesia...

in order to study the effects of rate and application time of nitrogen on grain yield of rainfed wheat, water use efficiency of rain (wue), nitrogen agronomic efficiency (nae) and soil moisture depletion (smd), one experimental farm was carried out in kurdistan province during 2012-2014. tratments were five rates of nitrogen (n0, n30, n60, n90 and n120) kg.ha-1 as urea with three application ti...

Sri Lanka, one of the pristine tropical islands located between latitudes 5° 55’ and 9° 51’ N and longitudes 79° 41’ and 81° 54’ E in the Indian Ocean near to the southern tip of the Coromandel Coast of the...

the goal of this research is the determining of planting date and providing agricultural calendar for corn in kermanshah province using climatic elements of temperature and rain fall. so, at first, long term  climatic statistics are collected from 2001 to 2011  and then  considered to temperature and rain fall parameters like  absolute maximum and minimum  in region during growth period, planti...

BACKGROUND weather predictions are a useful tool for informing public health planning and prevention strategies for non-injury health outcomes, but the association between winter weather warnings and fall-related injuries has not been assessed previously. OBJECTIVE to examine the association between fall-related injuries among older adults and government-issued winter weather warnings. METH...

Groundwater in the Todos Santos watershed in southern Baja California, and throughout the peninsula south of latitude 28°N, has values of (δ18 O‰, δD‰) ranging between (-8.3, -57) and (-10.9, -78). Such negative values are uncharacteristic of the site latitude near the sea level. Altitude effects do not explain the isotope data. Tropical depressions originating along the Pacific coast of North ...

Sulfur dioxide and nitrogen oxides are the primary causes of acid rain. In the United States, about two thirds of all sulfur dioxide and one-quarter of all nitrogen oxides come from electric power generation that relies on burning fossil fuels like coal. Acid rain occurs when these gases react in the atmosphere with water, oxygen, and other chemicals to form various acidic compounds. These acid...

An impact-type Joss–Waldvogel disdrometer (JWD), a two-dimensional video disdrometer (2DVD), and a laser optical OTT Particle Size and Velocity (PARSIVEL) disdrometer (PD) were used to measure the raindrop size distribution (DSD) over a 6-month period in Huntsville, Alabama. Comparisons indicate event rain totals for all three disdrometers that were in reasonable agreement with a reference rain...
