Most learning systems applied to problem solving have the goal of learning knowledge for solving problems more eeciently. However, very few systems have focused on the acquisition of planning operator descriptions. In this paper, we present a system that learns operator deenitions from the interaction with a completely unknown environment. In order to achieve better learning convergence, severa...

The snake-like robot is a limbless bionic widely used in unstructured environments to perform tasks with substantial functional flexibility and environmental adaptability complex environments. In this paper, the spiral climbing motion of on outer surface cylindrical object was studied based three-dimensional biological snake, we carried out analysis optimization motion-influencing factors. Firs...

In this work the selectivity of crosslinked organic solvent stable PBI membranes is tuned by varying molar ratio two grafting agents: a long flexible polymer modifier (Elastamine RE-1-1000, 1000 g mol-1) and small molecule (2-methoxyethylamine, 75 mol-1). Grafting exclusively with chain provided membrane molecular weight cut-off (MWCO) 2000 mol-1 in acetonitrile. Increasing proportion reaction ...

Epigenetic processes--including DNA methylation--are increasingly seen as having a fundamental role in chronic diseases like cancer. DNA methylation patterns offer a route to develop prognostic measures based directly on DNA measurements, rather than less-stable RNA measurements. A novel DNA methylation-based measure of the co-ordinated interactive behaviour of genes is developed, in a network ...
