background: a number of randomized trial studies and longitudinal researches emphasize that despite problems in social adjustment and cognitive damages, children with cancer demonstrate good emotional adjustment. methods: most of the research findings in this area are obtained using objective tools such as questionnaires. “vitality of children”, as a drawing tool, was used as a basis to draw a ...

in this paper, we consider a cooperative cognitive radio network in which there is an ofdm primary link and multiple single carrier secondary links.the primary link is required to maintain its secrecy rate above a predefined threshold. if the secrecy rate requirement is not satisfied, the secondary system help primary link to maintain its secrecy rate requirement. in doing so, the secondary trans...

Variation of frequency and voltage by load changes in a microgrid is a challenge in droop control method. Centralized restoration frequency or voltage in a microgrid requires communication link and therefore affects the advantage of decentralized droop control such as reliability, simplicity and inexpensiveness. This paper proposes a decentralized method that restores the frequency of a microgr...

This paper presents a method for the kinematical modeling of robot manipulator arms with flexible members. Development of such techniques are important for the improvement of robotic arms precision performance and their mechanical design. The approach employs the (4X4) Denavit-Hartenberg homogeneous transformations to describe the kinematics of light weight flexible manipulator arms. The method...

considering research contributions to translation studies in the iranian context , especially in the recent years , there is a remarkable improvement in terms of both quality and quantity of these studies . most of these studies can be classified in one of the following groups: ( 1 ) the studies which adopt a linguistic -oriented approach , ( 2 ) those with non - linguistic orientations coverin...
