Objective: Different educational tools are now commonly used in universities worldwide such as illustrations, audio and videotapes, etc. This study aimed to compare the efficacy of educational film and clinical demonstration for instruction of Fiber-Reinforced Composite (FRC) post restorations to dental students in Department of Restorative Dentistry.   Methods: This interventional study was ...

In robot programming by demonstration, we hypothesize that in a class of procedural tasks where the end goal primarily consists of the states of objects that are external to a task performer, one can significantly reduce complexity of a robot learner by not processing a human demonstrator’s motions at all. In this class of tasks, object behaviors are far more critical than human behaviors. Base...

We present a method for automatic grasp generation based on object shape primitives in a Programming by Demonstration framework. The system first recognizes the grasp performed by a demonstrator as well as the object it is applied on and then generates a suitable grasping strategy on the robot. We start by presenting how to model and learn grasps and map them to robot hands. We continue by perf...

background various researchers have shown that the health level, performance status, and quality of life (qol) are often less than expected especially in hemodialysis (hd) patients. objectives this study aimed to determine the effect of the two methods of educational programs on health- related qol (hrqol) in iranian hd patients. patients and methods in this quasi-experimental, pretest-posttest...

The special issue collects a subset of the best papers presented at the ICRA’05 workshop on the Social Mechanisms of Robot Programming by Demonstration. The workshop took place on April 21st 2005 in Barcelona, Spain, at the IEEE Conference on Robotics and Automation (ICRA’05). Eleven of the best papers presented at the workshop were subsequently submitted for peer review before publication in t...

Programming by demonstration systems acquire procedural knowledge from examples, and then use that knowledge to execute the learned procedure on new instances. We present an architecture, called version space algebra, for learning this type of procedural knowledge, and describe an implemented system for programming by demonstration in the text-editing domain. We present results showing the syst...

It has been shown that for k = 8 or 9, there exists a BIBD(v, k, 1) for all positive integers v == 1 or k (mod k(k-1)), with some possible exceptions. We show that such designs exist for 49 of these exceptional values. A balanced incomplete block design (BIBD) with parameters (v, k, 1) is a pair (X, A) where X is a v-set and A is a family of k-subsets (where 2 < k < v) called blocks, such that ...
