In this paper, magnetic powder brake is used to load the starting motor in design of test bed, so that loading and transmission stable reliable. The star type elastic coupling connect reduce vibration noise. At same time, high precision speed torque sensor improve accuracy data testing motor. After test, report can be generated automatically stored. reliability simulation calculation verified b...

The aim of this work is to present the methodological process design a device capable performing Bulge tests. This kind allows obtaining more information about plastic behavior material than one provided by traditional tensile test. engineering specifications were evaluated through QFD methodology. Then, basic was performed based on available analytical models such as thick-walled pressure vess...

This study aims to investigate preservice computer teachers‘ self-efficacy beliefs and achievement motivation levels for educational software development before and after the ―Educational Software Design, Development and Evaluation (ESDDE)‖ course. A pretest and post test design without a control group was employed. In 2008, 46 senior students (25 male and 21 female) who were enrolled at Comput...

We put forward initial results on lightweight phase-based control for dialogue systems as a test case of evolutionary development of such systems. A new design pattern for generalized phase-based processing is presented. A phase-based view of top-level control for dialogue systems is suggested in terms of the new pattern. The work verifies the generality of a previously reported development met...

One of the hardest problems in digital circuit design is test pattern generation for a complex device. This is difficult in part because it requires reasoning about how to control a device whose behavior can be extremely complex. Knowledge of the specific operations that the device was designed to perform can help solve this problem. The key observation is that a device’s designed behavior is o...

The research was conducted to compare the impacts of problem-based learning (PBL) and example-based learning (EBL) on the learning performance in an engineering domain. The research was implemented by means of experimental design. Specifically, a two-group experiment with a preand post-test design was used in this research. A total of 37 students were randomly assigned to PBL and EBL groups. A ...
