Quadruped robots have unique capabilities for motion over uneven natural environments. This article presents a stable gait for a quadruped robot in such motions and discusses the inverse-dynamics control scheme to follow the planned gait. First, an explicit dynamics model will be developed using a novel constraint elimination method for an 18-DOF quadruped robot. Thereafter, an inverse-dynamics...

job satisfaction is a positive or pleasant emotional state resulting from a person’s appreciation of his/her own job or experience. the study purpose was to model job satisfaction for teachers working in agricultural institutes within mazandaran province of iran. the study used a descriptive-correlative design . the statistical population (including all instructors working for agricultural inst...

the aim of this study was to test the model of the relationship between violence against women and aggressive behavior in children with mediation of maternal mental health. research design was correlation and path analysis. the study population included all of preschool children¢s mothers at the city of dezful. the sample was consisted of 250 pre-school children¢s mothers. that selected by mult...

Clickstream data provides information about the sequence of pages or the path viewed by users as they navigate a web site. We show how path information can be categorized and modeled using a dynamic multinomial probit model of web browsing. We estimate this model using data from a major online bookseller. Our results show that the memory component of the model is crucial in accurately predictin...

This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...
