The motion of a pushed, sliding workpiece
It occurs frequently in robotic applications that a robot manipulates a workpiece which is free to slide on a work surface. Because the pressure distribution supporting the workpiece on the work surface cannot in general be known, the motion of the workpiece cannot be calculated uniquely. Yet despite this indeterminacy, several researchers have shown that sliding motions can be employed to accu...
متن کاملThe motion of a pushed, sliding object
In many robotic applications, manipulation planning for an object free to slide on a surface is an import; oblem. Physical analysis of the object's motion is made difficult by the absence of information about 1 stribution of support of die object, and of the resulting frictional forces. This paper describes a n iproach to the analysis of sliding motion. The instantaneous motion of the object ca...
متن کاملThe motion of a pushed, sliding object : part 2 : contact friction
The physics of motion of a sliding object can be used to plan sensorless robot manipulation strategies based on sliding. Prediction of a sliding object's motion is difficult because the object's distribution of support on the surface, and the resulting frictional forces, are in general unknown. We describe a new approach to the analysis of sliding motion, which finds the set of object motions f...
متن کاملthe effect of pushed output collaborative tasks on the writing skills of efl learners
there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...

مفهوم فرضیه تولید اجباری سویین (1985)، بیانگر تسهیل یادگیری زبان دوم می باشد. این فرضیه پیشنهاد میکند که هنگامیکه دانش آموزان مجبور به شرکت در تولید زبان می شوند، این فرصت را دارند که پیامی دقیق، منسجم و مناسب را ارائه دهند. با توجه به کمبود تحقیقات کمی در جهت حمایت یا رد تولید اجباری، مطالعه حاضر اقدام به ایجاد داده های کمی جهت اثر تولید اجباری نموده است. هدف از این مطالعه از دو قسم می باشد. ا...
