Storm runoff events in the flooding season affect the water quality of reservoirs and increase risks to the water supply, but coping strategies have seldom been reported. The phenomenon of turbid current intrusion resulting in water turbidity and anoxic conditions reappearing after storm runoff, resulting in the deterioration of water quality, was observed in the flooding season in the deep can...
Floods are among the most devastating natural disasters and expected to become more severe with changing climate population growth. Flood forecasting is one of key components flood risk reduction. The potential for seasonal through indexes has not been studied West Africa so far. This work investigates how indicators can be used predict in advance, several months ahead season, above or below no...
In this paper, we investigate the out-of-sample forecasting ability of a genetic program to approach the dynamic evolution of the Yen/US$ and Pound Sterling/US$ exchange rates, and verify whether the method can beat the random walk model. Later on, we use the predicted values to generate a trading rule and we check the possibility of obtaining extraordinary profits in the Foreign Exchange Marke...
This paper studies the effect of varying the depth of look-ahead for heuristic search in temporal difference (TD) learning and game playing. The acquisition position evaluation functions for the game of Othello is studied. The paper provides important insights into the strengths and weaknesses of using different search depths during learning when 2-greedy exploration is applied. The main findin...
Ionizing shock waves in magnetofluiddynamics occur when the coefficient of electrical conductivity is very small ahead of the shock and very large behind it. For planner motion of plasma, the structure of such shock waves are stated in terms of a system of fourdimensional equations. In this paper, we show that for the above electrical conductivity as well as for limiting cases, that is, when th...
to determine whether teenagers and young adults with attention deficit hyperactivity disorder (adhd) have more motor vehicle citations and crashes and are more careless drivers than their normal peers. in fact, studies have found that teenagers and adults with attention deficit disorder are nearly twice as likely as the general population to have had their licenses suspended. people with adhd h...
Population dynamics indices of parasites infected on cultured ornamental fishes according to the climatic changes in kurunagala district,Sri Lanka were estimated.Sample of gold fishes and koi carps which were harvested from mud ponds in ornamental fish breeding and traning center was examined for ecto parasites. Four population indices were calculated for each abundant parasite species and dive...
Arctic terrestrial ecosystems are major global sources of methane (CH4); hence, it is important to understand the seasonal and climatic controls on CH4 emissions from these systems. Here, we report year-round CH4 emissions from Alaskan Arctic tundra eddy flux sites and regional fluxes derived from aircraft data. We find that emissions during the cold season (September to May) account for ≥ 50% ...
Male golden-collared manakins gather on leks and perform an acrobatic display to attract females. In temperate breeding species, testosterone (T) activation of courtship displays has been well studied. Few studies have examined T activation of displays in tropical species; even fewer have explored the activational role of T in elaborate courtship displays such as in the manakin. In some tropica...
