The purpose of this study is to explore the acceptance of Tablet PCs in K-12 education among parents and communities. Because of the obstacles and controversies existed in world-wide "One Tablet PC per Child" projects, the authors used the Technology Acceptance Model to identify the potential factors that may influence the acceptance of Tablet PCs from the perspectives of parents and communities,...
A feedback linearization based adaptive control scheme is developed for multivariable nonlinear systems subject to uncertain failures. The use of a direct adaptive actuator failure compensator and a linear feedback controller leads to error equations suitable for deriving adaptive update laws for the direct control signal. The key new design feature is the estimation of both the failure patterns and...
This paper considers the problem of non-fragile reliable H∞ control problem for a class of delta operator switched systems with actuator faults. A new approach is proposed to deal with the uncertain matrices multiplication phenomenon which appears in non-fragile reliable control. Based on average dwell time approach, a sufficient condition that can guarantee a prescribed H∞ performance of the closed-loop...
We address the problem of room structure recognition from a 360 cylindrical panorama. The proposed approach first transforms the original panorama into four perspective projected sub-images, then predicts the final layout based on a holistic parameterization framework via candidate evaluation using a linear scoring function, whose weights are trained on a normal indoor image data set. Experiments...
This case study investigated mathematics teachers' perspectives and the status of the applications of information technology (IT) in a key senior high school in China. A questionnaire was conducted to collect data. This research focused on teachers' perceptions on the role of IT in mathematics classroom instruction, as well as the status of the technology integration in their class. Results of the...
To study the influence of the circulation distribution principle to the centrifugal pump, the present paper studied the pump head character, efficiency character and NPSH character of the pump under three circulation distribution laws. And 2D-design method is adopted. The rules how the circulation distribution influences the performance of centrifugal pump is obtained through the research.
Mobile video surveillance system based on ARM9 uses unique high-bandwidth business applications of 3G wireless network. The design of hardware and software of embedded monitoring system is described. The running platform of 3G network show that the system can work well in the circumstances of the limited bandwidth.
A helper thread active prefetching technology was proposed to make the prefetching thread in the helper core run ahead the main thread in the main core. The helper thread attempted to trigger future cache miss events in advance of accessing by the main thread to avoid the memory missing latency. As a special prefetching mechanism, compared with the traditional helper thread method, the problem of...
This paper refers to transaction cost, studying the stability of cartel and comparing it to the traditional balance scale of cartel through the perspective of a regular static model. Thus, we make 2 conclusions: Firstly, after introducing transaction cost, it's hard to meet the requirements of cartel's inner stability. Secondly, transaction cost reduces the profit of cartel and decreases marginal...
