A Warm Reading of Sunshine Sketches of a Little Town

Stephen Leacock(1869-1944) is one of the founding parents of Canadian letters and literature. 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.

Relevant theoretic account of humor in sketches

Based on the relevant theory, this paper makes an analysis of humor in Chinese popular art form --sketch. It is believed that the maximal relevance and the optimal relevance of utterances, explicature and implicature of utterances, and the efforts made by hearers in dealing with utterances are three important aspects in showing humorous effects in sketches, among which sketch actors＇ violating the mutual cognitive environment so as to create an unexpected effect on hearers is the core in creating humor in sketches. Through analyzing some excerpts from the sketch Yesterday.Today.Tomorrow, the author tries to explore the relevance nature of language in sketch and creation of humor in it.

A Situated Learning Practice for Language Teaching Classes： Teaching Spoken English With Authentic Sketches

SL （situated learning） is a term first proposed by Lave and Wenger （1991） as a model of learning in a community of practice. 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.

Flower solid modeling based on sketches

In this paper we propose a method to model flowers of solid shape. 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.

Lapel Pattern Recognition in Flat Sketches Based on Lapel Model

Taking lapels as examples,the purpose of this paper is to study the problem of recognizing the same clothing component in the flat sketches. 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%.

A digital assistant for shading paper sketches

We present a mixed reality-based assistive system for shading paper sketches.Given a paper sketch made by an artist,our interface helps inexperienced users to shade it appropriately.Initially,using a simple Delaunaytriangulation based inflation algorithm,an approximate depth map is computed.The system then highlights areas(to assist shading)based on a rendering of the 2.5-dimensional inflated model of the input contour.With the help of a mixed reality system,we project the highlighted areas back to aid users.The hints given by the system are used for shading and are smudged appropriately to apply an artistic shading to the sketch.The user is given flexibility at various levels to simulate conditions such as height and light position.Experiments show that the proposed system aids novice users in creating sketches with impressive shading.

Deep3DSketch-im:rapid high-fidelity AI 3D model generation by single freehand sketches

The rise of artificial intelligence generated content(AIGC)has been remarkable in the language and image fields,but artificial intelligence(AI)generated three-dimensional(3D)models are still under-explored due to their complex nature and lack of training data.The conventional approach of creating 3D content through computer-aided design(CAD)is labor-intensive and requires expertise,making it challenging for novice users.To address this issue,we propose a sketch-based 3D modeling approach,Deep3DSketch-im,which uses a single freehand sketch for modeling.This is a challenging task due to the sparsity and ambiguity.Deep3DSketch-im uses a novel data representation called the signed distance field(SDF)to improve the sketch-to-3D model process by incorporating an implicit continuous field instead of voxel or points,and a specially designed neural network that can capture point and local features.Extensive experiments are conducted to demonstrate the effectiveness of the approach,achieving state-of-the-art(SOTA)performance on both synthetic and real datasets.Additionally,users show more satisfaction with results generated by Deep3DSketch-im,as reported in a user study.We believe that Deep3DSketch-im has the potential to revolutionize the process of 3D modeling by providing an intuitive and easy-to-use solution for novice users.

Sketches of the Chinese Women's Soccer Team

ON 6 August 1996, the women’s football team returned to Beijing from Atlanta with other Olympic athletes. Finally, after years of preparation, they could remove their athletic gear and don suits and dresses. For many years, the heavy schedule of training and competitions allowed the team few opportunities to wear skirts. Even if they did, some of the women dared not—their legs were full of scars. Some didn’t care and said: "After

Easy modeling of realistic trees from freehand sketches

Creating realistic 3D tree models in a convenient way is a challenge in game design and movie making due to diversification and occlusion of tree structures. 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.

基于近似测量算法Sketch的高精度区块链异常检测机制

区块链存在网络动态性强和其管理困难等问题,使得区块链普遍存在DDoS攻击和账户接管等异常现象.现有区块链异常检测方法多从所有区块链账户中提取历史交易信息和交易频率等特征加以分析以甄别异常.然而,随着区块链数据规模的不断扩大,现有方法在提取特征时面临内存消耗高、检测精度低的挑战.为此,提出了一种高检测精度、低内存开销的区块链异常检测机制,该机制采用近似测量算法将区块链异常检测转化为异常交易账户检测,包括区块内异常账户和跨区块异常账户.对于区块内异常账户,即仅存在于单个区块内的异常账户,使用Sketch算法进行账户识别,精度高.而对于存在于多个区块且难以通过单个区块信息检测到的跨区块异常账户,则通过聚合和分析多区块信息进行账户的准确检测.使用包含88847个区块的真实区块链数据评估上述机制.实验结果表明,与现有代表性方法对比,所提出的机制将区块链异常检测的召回率最高提升了6.3倍,F1分数最高提升了4.4倍.因此,提出的高精度区块链异常检测机制对于规范区块链交易行为、维护系统安全性具有意义.

分布式网络中连续时间周期的全局top-K频繁流测量

在分布式网络中,测量top-K频繁流对资源分配、安全监控等应用至关重要。现有的top-K频繁流测量工作存在不适用于测量分布式网络流量或只考虑单时间周期等局限。为此,提出了分布式网络中连续时间周期的全局top-K频繁流测量方案,在分布节点中布置了紧凑的概率数据结构来记录网络流信息,每个时间周期结束后分布节点向中心节点发送必要信息,中心节点汇聚得到从测量开始至当前时间周期的全局top-K频繁流。考虑到每条流可能出现在一个或多个测量节点,使用了不同的方法来减少传输开销。对于每条流只会出现在单一节点的情况,采用传输分段最小值的方法来获得阈值,实验结果表明这种方法减少了全量传输超过50%的传输开销。对于每条流会出现在多个节点的情况,提出了多阶段无误差处理方法和单阶段快速处理方法,分别应对不能容忍误差的场景和实际高速网络流量,相比每个时间周期都使用已有单周期方法,传输开销的实验表现降低了两个数量级。最后还提出了一种利用历史平均增值信息降低通信延迟的方法,实验结果表明该方法有效降低了限制信息的平均相对误差。
