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 purpose of this study was to evaluate the effects of Nano-silver (NS), calcium chloride (CaCl2) and their combinations on Gerbera jamesonii ‘Carambole’ cut flowers. The experiment was conducted as a completely randomized design (CRD) with 10 treatments and four replications, with three flowers in each replication. Treatments consisted of 5 mg L-1 NS, 1% and 2% CaCl2, 5 mg L-1 NS+ 1% CaCl2, ...

This paper deals with the high-speed switching operation of a main circuit when using silicon carbide (SiC) complementary metal-oxide semiconductor (CMOS) and power module for drive. When developed SiC CMOS gate buffer, we experimentally achieved turn-on turn-off speeds about -100 80 V/ns at DC bus voltage 600 V load current 20 A. Based on I-V characteristics charge MOSFET, approximate time was...

the earliest evidences on circulation of avian influenza (ai) virus on the iranian poultry farms date back to 1998. great economic losses through dramatic drop in egg production and high mortality rates are characteristically attributed to h9n2 ai virus. in the present work non-structural (ns) genes of 10 iranian h9n2 chicken ai viruses collected during 1998-2007 were fully sequenced and subjec...
