The research seeks to examine the role of life skills concerning attitude towards narcotic drugs and students’ self-esteem. The research design is experimental and includes pilot plans as well as pre-test and post-test control group designs. The sample groups include 60 male students (30 students in the pilot group an 30 students in the control group). The research results are as follows: 1.Of...

target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...

this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...

Play space is one of the child's favorite spaces that greatly affects the child's mental state and the proper design of these environments can improve their emotional intelligence. Emotional intelligence is the capacity or ability to organize the feelings and emotions of oneself and others, to motivate oneself and effectively control one's emotions and use them in relationships with others. The...

this thesis is presented 10 ghz voltage controlled ring oscillator for high speed application. the voltage controlled ring oscillator was designed and fabricated in 0.13یm cmos technology. the oscillator is 7-stages ring oscillator with one inverter replaced by nand-gate for shutting down in the ring oscillator during idle mode. tri-state inverter was used to control of 126 bit vector in ri...
