This research focuses on proposing an optimal trajectory planning and control method of two link rigid-flexible manipulators (TLRFM) for Dynamic Object Manipulation (DOM) missions. For the first time, achievement of DOM task using a rotating one flexible link robot was taken into account in [20]. The authors do not aim to contribute on either trajectory tracking or vibration control of the End-...

This study investigates the combined effects of task-based careful online planning condition and the storyline structure of a task on L2 oral performance (complexity, accuracy, and fluency). 60 intermediate EFL learners were randomly assigned to four groups (n = 15). Participants were asked to perform two tasks with different degrees of storyline structure (structured and unstructured) under tw...

In this paper we address the problem of generating preferred plans by combining the procedural control knowledge specified by Hierarchical Task Networks (HTNs) with rich user preferences. To this end, we extend the popular Planning Domain Definition Language, PDDL3, to support specification of simple and temporally extended preferences over HTN constructs. To compute preferred HTN plans, we pro...

niques is now the world champion computer program in the game of Contract Bridge. As reported in The New York Times and The Washington Post, this program—a new version of Great Game Products’ BRIDGE BARON program—won the Baron Barclay World Bridge Computer Challenge, an international competition hosted in July 1997 by the American Contract Bridge League. It is well known that the game tree sear...

Despite the recent advances in planning for classical domains, the question of how to use domain knowledge in planning is yet to be completely and clearly answered. Some of the existing planners use domain-independent search heuristics, and some others depend on intensively-engineered domainspecific knowledge to guide the planning process. In this paper, we describe an approach to combine ideas...

Industrial robots are programmed to repeat a sequence of well-defined tasks, e.g. deburring, cutting and welding. The production cycle time is directly influenced by the task order as well way trajectories linking this tasks generated. In letter, we present an optimization approach that minimizes overall movements duration robots. We propose fast algorithm generates sequenced near-optimal solut...

The mental number line (MNL) hypothesis is that numbers are mentally represented in spatial format, particularly in leftto-right orientation among Westerners. The MNL has received support from various paradigms, but it remains controversial as it is challenged by alternative models. Here we used an individual differences approach to assess spatialnumerical associations (SNAs) across a variety o...

Recent research has provided methods for coordinating the individually formed concurrent hierarchical plans (CHiPs) of a group of agents in a shared environment. A reasonable criticism of this technique is that the summary information can grow exponentially as it is propagated up a plan hierarchy. This paper analyzes the complexity of the coordination problem to show that in spite of this expon...
