abstractthe understanding of water resources for the purpose of ground and surface water management as two inseparable systems is great importance. in this study by examining the time series of climatic variables (precipitation), hydrological (flow and consume) and the level of water table, the parameters associated with each other and with fluctuating water table can be realized. there was a d...

biological and demographic parameters of the mealybug ladybird, cryptolaemus montrouzieri (mulsant) were evaluated on citrus mealybug, planococcus citri (risso) and obscure mealybug, pseudococcus viburni (signoret) under 24 ± 2 ºc, 80 ± 5% relative humidity and a photoperiod of 16:8 (l: d) h. the mealybugs had a significant effect on developmental time and reproductive and demographic parameter...

There are two main trends in the area of home and service robotics. The classical one aims at the development of a single skilled servant robot, able to perform complex tasks in a passive environment. The second, more recent trend aims at the achievement of complex tasks through the cooperation of a network of simpler robotic devices pervasively embedded in the domestic environment. This paper ...

The Table Maker's Dilemma is the problem of always getting correctly rounded results when computing the elementary functions. After a brief presentation of this problem, we present new developments that have helped us to solve this problem for the double-precision exponential function in a small domain. These new results show that this problem can be solved, at least for the double-precision fo...
