the purpose of this research was to determine the effect of volleyball skills training and problem solving on adolescent girls self-efficacy. the research method was semi-experimental and conducted in as pre-test and post-test with four experimental groups.the research statistical population consisted of all first grade students of broujen high schools in the academic year of 2009-2010(1388-89s...

We consider the problem of map learning while maintaining ground-truth pose estimates. Map learning is important in tasks that requir ea model of the envir onmentor some of its featur es. As a robot collects data, uncertainty about its position accumulates and corrupts its knowledge of the positions from which observations are taken. We addr essthis problem by employing cooperative localization...

This paper looks at the experience of teaching on a module where problem-solving is taught first, then programming. The main tools for the problemsolving part, alongside two problem-solving approaches, are tasks based on using Mindstorm (LEGO, Denmark) robot kits. This is being done as a foundation step before the syntax of a language (Java) is taught. Results of student evaluation will be pres...

The development of a robust fiber-optic proximity sensor is presented. A method is proposed by which to solve tli-oblem of robustness of amplitudeand phase-modulated electro optical proximity sensors to variations in surface-reflection characteristics, a n d to reduce the influence of dis tance a n d or ientat ion measurements on one other. The method comprises three different methodologies, wh...

Objective Objective: Gelatinases degrade extracellular matrix (ECM) components to make physiological remodeling and contribute to pathological tissue destruction in endometriosis. It is known that gelatinases’ function is resistant to suppression by progesterone in endometriosis. The ability of progesterone to impact gene expression depends on the progesterone receptor-A/-B (PR-A/PR-B) ratio. A...

In this paper, we have proposed a new paradigm for the feature grouping problem, with sp ecial emphasis on the problem of particle tracking. First and foremost , we sugg est a mathematical enco ding of the pr oblem , which takes into account metric cons traints specific to the pr obl em , perceptual pr operties of t he image and physics pr operties of the ph enomena. Second, we prop os a new st...

Previous research shows that organization architecture relates to the architecture of a product under development, and recent studies compare proprietary versus open source software (OSS) as examples of integrated and distributed forms of software development, respectively. This study goes a step further to investigate the correspondence of organization and product architectures by comparing si...
