An adaptive subdivision method is proposed in this work for automatic post-processing of a 3D graphic model of coarse resolution. The method is an improved version of the Modified Butterfly Scheme (MBS) developed by Zorin et al. The main contribution of this work is to exploit the local smoothness information of a surface for adaptive refinement of a coarse 3D graphic model. With this approach,...

An efficient numerical method for the design and synthesis of compensator for a relay type control system is developed and discussed. Previous works based on the interactive graphic method are reviewed and it is shown that the combination of the trequency and time domain numerical techniques provide a powerful tool in design of a wide class of relay control systems. An example is presented to d...

this study investigated 1) whether the effect of teacher-developed graphic organizers vis-à-vis student-developed ones was more significant on improving intermediate efl learners’ writing, and 2)whether the use of both graphic organizers had any impact on their writing. the participants were selectedin two stages: 130 students sat for a piloted proficiency test. those who scored above half ofth...
