Hemingway＇s use of objective correlatives was a trace mark, and the literary editors at The New Yorker urged their writers to slow down the emphasis on movement and plot in order to recreate a certain mood which would favour the perception of objects, anecdotes, and details. The impressionistic device works very much in the same way that an advertisement would do. It is meant to persuade the audience. The apparently non-commitant vision of reality shows in fact the author＇s point of view. The apparent simplicity is meant for a very wide audience and its deepest meaning suggests the scope of the particular visual aids working at the deepest level of consciousness展开更多

Development and usage of medical image processing toolkit have become an important research trend. It is a fundamental task to master their image rendering principles and data organization mode in order to use these toolkits. MITK （Medical Imaging Toolkit, from www.mitk.net） with the important characteristics of inheritance and virtual function uses the Object-Oriented design approach. This paper researches the data organization mode and coordinate translation of MITK and presents an algorithm based on OpenGL to rewrite the image-rendering function of MITK. Using the algorithm, the rewritten rendering function has the same rendering effect as the one in MITK. By rewriting the virtual image-rendering function and using the capability that a view window can load many data model, users can neatly render various graphics and images. Though the researches of this paper are based on the mitklmageModel class, the algorithm also is fit for 2D ＂widgets＂ class.展开更多

The number of geometric elements in spectra was found for four running parameters and different number of gratings by layers. The shape of trajectories was determined in the corresponding cases. The relationships between parameters were found which could help in reducing the intervals of parameters, in particular the relationship between the inverse aspect ratios. The numerical simulation and the physical experiment were in a good agreement with the theory. The proposed technique seems to be helpful in estimation of occurrence of moir6 patterns in visual displays which makes possible the minimization in the spectral domain without calculation of spectra.展开更多
