To improve the accuracy and efficiency of task decomposition of R&D (Research and Development) projects, a new decomposition method based on product structure tree was proposed. The relevance between product structure tree and work breakdown structure (WBS) was analyzed through their natural quality and association relations. The mapping rules between product components and project tasks were d...

Integrated development environments have been designed and engineered to display structural information about the source code of large systems. When a development task lines up with the structure of the system, the tools in these environments do a great job of supporting developers in their work. Unfortunately, many development tasks do not have this characteristic. Instead, they involve change...

Adaptation is one of the most problematic steps in the design and development of Case Based Reasoning (CBR) systems, as it may require considerable domain knowledge and involve complex knowledge engineering tasks. This paper describes a general framework for substitutional adaptation, which only requires analogical domain knowledge, very similar to the one required to define a similarity functi...

the present study adopts the perspective that metacognitive strategy instruction is bound to occur inside the classroom especially on oral tasks. accordingly, the researchers investigated whether metacognitive strategy instruction prior to oral tasks was more successful than conventional ways in improving efl learners’ oral proficiency. to this end, 56 participants studying in a language school...

To analyze a production system and find its best configuration, the technique of simulation-based optimization is often utilized. This paper describes a practical exercise used at the University of Skövde, Sweden to teach simulation-based optimization to students using a physical Lego factory. The Lego factory provides a setting that is close to reality, and optimizing its production assists st...

production of highly viscous tar sand bitumen using steam assisted gravity drainage (sagd) with a pair of horizontal wells has advantages over conventional steam flooding. this paper explores the use of artificial neural networks (anns) as an alternative to the traditional sagd simulation approach. feed forward, multi-layered neural network meta-models are trained through the back-error-propaga...

framed in a cognitive approach to task-supported l2 vocabulary learning, the present study used a pedagogical approach to investigate the relative effectiveness of tasks with different involvement loads on the vocabulary knowledge of iranian efl learners. the goal was to investigate the way that the construct of involvement load is related to the input hypothesis (krashen, 1985) and the output ...

The paper investigates whether the classical socio-technical matrix that differentiate 4 quadrants of social-technical system: people, structure, tasks and technology can still be useful for practical purposes. The paper gives a positive answer on the question, provided that the level of abstraction in defining these four quadrants is increased to deal with culture, type of structure, methods (...

this study investigated how awareness affected learners’ intake and production in relation to their cognitive styles. it is assumed that learners’ cognitive styles may affect their ability to notice particular features in the input and, consequently, their intake and production. adult learners of english were exposed to four english structures through four sets of problem-solving tasks, followe...
