global warming has brought about changes in meteorological variable time series. these changes, accompanied with serious human intervention in nature, has resulted in hydrological changes. so the effects can be tracked down by the trend of the time series. the purpose of this study is to analyze and compare the monthly and annual trends of temperature, precipitation as well as stream flow time ...

In this paper a multijoint robot f o r sewer inspection tasks i s presented. In order t o increase the operating scope the robot has been made able t o run round or over obstacles, to follow sewage branches and is aimed t o work wirelessly unlike mos t other sewer inspection robots. A s a result of the wireless approach the robot has to carry an energy resource and mus t be able to act autonomo...

We describe statistical methods based on the t test that can be conveniently used on high density array data to test for statistically significant differences between treatments. These t tests employ either the observed variance among replicates within treatments or a Bayesian estimate of the variance among replicates within treatments based on a prior estimate obtained from a local estimate of...
