Predicting the degree of nativeness of a student's utterance is an important issue in computer-aided language learning. This task has been addressed by many studies focusing on the segmental assessment of the speech signal. To achieve improved correlations between human and automatic nativeness scores, other aspects of speech should also be considered, such as prosody. The goal of this study is...

this commentary reviews a recent piece by burton and rycroft-malone on the use of resource based view (rbv) in healthcare organizations. it first outlines the core content of their piece. it then discusses their attempts to extend rbv to the analysis of large scale quality improvement efforts in healthcare. some critique is elaborated. the broader question of why rbv seems to be migrating into ...

In this paper, we present the capability of our ontology matching tool YAM++. We show that YAM++ is able to discover mappings between entities of given two ontologies by using machine learning approach. Besides, we also demonstrate that if the training data are not available, YAM++ can discover mappings by using information retrieval techniques. Finally, we show that YAM++ is able to deal with ...

Agent coalition is an important manner of agents’ coordination and cooperation. Forming a coalition, agents can enhance their ability to solve problems and obtain more utility. In this paper, a novel multi-task coalition parallel formation strategy is presented, and the conclusion that the process of multi-task coalition formation is a Markov Decision Process is testified theoretically. Moreove...

Cloud computing is a type of parallel and distributed system consisting of a collection of interconnected and virtual computers. With the increasing demand and benefits of cloud computing infrastructure, different computing can be performed on cloud environment. One of the fundamental issues in this environment is related to task scheduling. Cloud task scheduling is an NP-hard optimization prob...

abstract in iran, most english teachers’ method of teaching writing is merely to have students do some writing exercises or simply to give them writing tests without any instruction, but writing is not an easy task for students, and teachers should be able to do more to facilitate their students’ writing. one of the ways to aid writing is dynamic assessment via graduated prompt. the graduated p...

In view of Min-Min algorithm prefers scheduling small tasks and Max-Min algorithm prefers scheduling big tasks led to the problem of load imbalance in cloud computing, a new algorithm named Min-Max is proposed. Min-Max makes good use of time of greedy strategy, small tasks and big tasks are put together for scheduling in order to solve the problem of load imbalance. Experimental results show th...

With the emergence of Cloud computing and Grid Computing, Distributed Scheduling (DS) problems have attracted attention by researchers in recent years. Distributed scheduling requires an uneven distribution of tasks on individual processors. Different heuristic based algorithms to perform the task scheduling have been proposed by the various researchers. This paper offers a new strategy for tas...
