A New Method of Mobile Robot Navigation: Shortest Null Space
In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

متن کاملComparison the Effect of two Methods of Internship and Apprenticeship in the Field on Clinical Competence of Nursing Students
Introduction: Several studies show that apprenticeship in the field have not been able to improve the professional ability and competence of students to the desired level. Therefore, this study was conducted to Compare the effect of two methods of internship and apprenticeship in the field on clinical competence of nursing students. Methods: This is a quasi-experimental study in which two meth...
