In the early 20thcentury, his reputation as a humorist and a political economist was not limited by the boundaries of Canada but spread around the world. As one of his works, Sunshine Sketches of a Little Town has attracted world-wide admiration. It is a series of vignettes dramatizing the comedy of day-to-day life in Mariposa. It is bathed in the warm sunshine for all of us to laugh at as one of us remembers the little towns we might have known or come from. As a matter of fact, Leacock employs several techniques in his writing for humorous effect. This paper elaborates on the auther and the work, and makes an analysis on the character—Smith.展开更多

According to Lave and Wenger （1991）, learning should not be viewed as simply the transmission of abstract and decontextualised knowledge from one individual to another, but a social process whereby knowledge is co-constructed. The exposure to spoken language and cultural elements of foreign language is the best way of teaching the language itself rather than grammatical patterns and rules of the language. In this study, we aim to review ＂situational learning approach＂ in context with its role and efficiency of teaching spoken language. An experimental study was conducted on the university students in the preparatory classes at the School of Tourism of Erzincan University. Twelve male and 11 female students in the control group and 14 male and 10 female students in the experimental group took part in the research. The language levels of the students were determined by a language proficiency test which is used as pre-test of the study. Language proficiency test composed of mainly dialogues including spoken language patterns. After eight weeks of lectures with authentic sketches which were used as reading materials in experimental group and classical reading materials in control group, the students were given the same language proficiency test as post-test. When pre- and post-test results were evaluated, significant difference was found between the pre- and post-test results of the subjects on behalf of the students in the experimental group. It is concluded that spoken language can be achieved by authentic sketches which are designed to serve as a situated learning setting.展开更多

Based on (Ijiri et al., 2005)’s method, we separate individual flower modeling and inflorescence modeling procedures into structure and geometry modeling. We incorporate interactive editing gestures to allow the user to edit structure parameters freely onto structure diagram. Furthermore, we use free-hand sketching techniques to allow users to create and edit 3D geometrical elements freely and easily. The final step is to automatically merge all independent 3D geometrical elements into a single waterproof mesh. Our experiments show that this solid modeling approach is promising. Using our approach, novice users can create vivid flower models easily and freely. The generated flower model is waterproof. It can have applications in visualization, animation, gaming, and toys and decorations if printed out on 3D rapid prototyping devices.展开更多

Supposing that the four lines in a lapel are concurrent and symmetrical,a mathematical lapel model is built. Then,a novel method for lapel recognition in fashion flat sketches based on the lapel model is proposed. In the image preprocessing stage, the images need to be cropped for two times in order to remove the blank background and extract the region of interest,respectively. In the concurrent recognition stage,line detection,θ selection,and curve fitting are applied to limiting candidate lines. In the symmetrical recognition stage, k-means clustering algorithm is employed to divide the selected lines into four clusters. The threshold values of the difference of corresponding weighted θ are set as lapel recognition criteria. Experiments demonstrate that the recognition accuracy of the proposed method is obtained at about 91. 7%.展开更多

Current sketch-based and imagebased approaches for fast tree modeling have limitations in effect and speed, and they generally include complex parameter adjustment, which brings difficulties to novices. In this paper, we present a simple method for quickly generating various 3D tree models from freehand sketches without parameter adjustment. On two input images, the user draws strokes representing the main branches and crown silhouettes of a tree. The system automatically produces a 3D tree at high speed. First, two 2D skeletons are built from strokes, and a 3D tree structure resembling the input sketches is built by branch retrieval from the 2D skeletons. Small branches are generated within the sketched 2D crown silhouettes based on self-similarity and angle restriction. This system is demonstrated on a variety of examples. It maintains the main features of a tree： the main branch structure and crown shape, and can be used as a convenient tool for tree simulation and design.展开更多
