A task-driven imaging framework for prospective fluence field modulation (FFM) is developed in this paper. The design approach uses a system model that includes a parameterized FFM acquisition and model-based iterative reconstruction (MBIR) for image formation. Using prior anatomical knowledge (e.g. from a low-dose 3D scout image), accurate predictions of spatial resolution and noise as a funct...

The main problem of transportation is the very high growth vehicles causing congestion, resulting in various derivative impacts such as pollution, fuel waste, time value, and other environmental problems. This can be solved by Transportation Demand Management (TDM). TDM a combination strategies, which strategy should chosen whose priority depends on conditions each region. research was conducte...

Introduction: Human factor analysis has been identified as the most common cause of accidents in natural gas transportation and distribution facilities. The occurrence of accidents at these systems, especially gas reduction stations located in residential and industrial areas, has had catastrophic consequences. Therefore, this study aimed at analyzing critical tasks and human error assessment u...

The basal ganglia and prefrontal cortex play critical roles in category learning. Both regions evidence age-related structural and functional declines. The current study examined rule-based and information-integration category learning in a group of older and younger adults. Rule-based learning is thought to involve explicit, frontally mediated processes, whereas information-integration is thou...

Robot soccer is played in a dynamic environment. All robots in a team should select their task dynamically and adaptively in a cooperative manner. This paper proposes a framework for task and role selection strategy for distributed multi-robot coordination and its application to robot soccer. To deal with such a dynamic environment, context-based cooperation method is provided. The robot team h...

Speaking assessment is still construed as a complicated, under-researched process from the vantage point of tasks and rater characteristics. The present study aimed at investigating if and how English Major and none English Major teachers differ in their perception of the construct of oral proficiency while assessing learners’ L2 oral proficiency.  To this end, 38 male and female non-native EFL...

In order to determine the relationship between diary and questionnaire on measuring listeningstrategies, 25 students were selected. All the subjects who were the researchers’ ownstudents, study English as a second language. They wrote diaries about their use of listening.Strategies within 8 weeks. They also took the listening strategy questionnaire at the end of theterm. The students’ questionn...
