If you are mid-career, out of work and looking, you＇ve probably already figured this one out： The tried-and- true job-hunting techniques that served you so well in the past no longer fill the bill. While you were faithfully toiling away for the same employer, maybe for decades, a lot changed. Today it＇s a brave new world of social media and digital résumés and Google-ability. 相似文献

Applying homogeneous coordinates, we extend a newly appeared algorithm of best constrained multi-degree reduc- tion for polynomial Bézier curves to the algorithms of constrained multi-degree reduction for rational Bézier curves. The idea is introducing two criteria, variance criterion and ratio criterion, for reparameterization of rational Bézier curves, which are used to make uniform the weights of the rational Bézier curves as accordant as possible, and then do multi-degree reduction for each component in homogeneous coordinates. Compared with the two traditional algorithms of "cancelling the best linear common divisor" and "shifted Chebyshev polynomial", the two new algorithms presented here using reparameterization have advantages of simplicity and fast computing, being able to preserve high degrees continuity at the end points of the curves, do multi-degree reduction at one time, and have good approximating effect. 相似文献

This paper presents a quadratic programming method for optimal multi-degree reduction of Bézier curves with G1-continuity. The L2 and l2 measures of distances between the two curves are used as the objective functions. The two additional parameters, available from the coincidence of the oriented tangents, are constrained to be positive so as to satisfy the solvability condition. Finally, degree reduction is changed to solve a quadratic problem of two parameters with linear constraints. Applica- tions of degree reduction of Bézier curves with their parameterizations close to arc-length parameterizations are also discussed. 相似文献

The Internet is becoming increasingly widespread and changing the way that we are teaching and learning. The potential of the Internet enhance cognitive learning, develop problem-solving and higher-level thinking skills, and extend physical and mental ability. There are various functions of the Internet in the context of primary education for teachers’ professional use, enhancing and extending teaching and learning. 相似文献

0. Introduction
Advances in computer analysis of the English language have shown that lexical patterns are widespread in language use. Some researchers call them “lexical phrases“ (Nattinger and DeCarrico,1992) or “lexical chunks“ (Lewis, 1993); others use the term “multi-word chunks“ or just “chunks“of language. Whatever the terms are, they are characteristic of language use and language acquisition and present advantages for language teaching and learning. The lexical approach to English teaching has received interest in recent years as an alternative to grammar-based approaches. The lexical approach concentrates on developing learners‘ skills in understanding and using words and word combinations.…… 相似文献

The bi-direction of cross-cultural communication determines culture teaching should include both target culture and native culture.Currently,however,mere emphasis of target culture with ignoring native culture has resulted in "two-skin"phenomenon and"aphasia of Chinese culture".Therefore,this paper aims to underline native culture teaching,to explore proper techniques for native culture teaching,to achieve integration of target culture and native culture,to enhance studentséxpressive competence in native culture and finally to carry out effective cross-cultural communication. 相似文献

Border crossing is a metaphoric term in sociolinguistics referring to a blurring of English use across different domains of social discourses.This article shows how border crossing in English job-seeking discourse is manifested in a real-life English creative résumé,and how this phenomenon brings about two related consequences,informalization and marketization,through critically analyzing the informal and promotional features of the résumé.It then reaches the conclusion that such border crossing phenomenon reflects a voice by the young in reconstructing their self-identities in job-seeking discourse in post-industrialized,post-modern western societies. 相似文献

The anaphora resolution firstly relies on the special association between the anaphor and the antecedent.But this kind of associa tion may not result in the accomplishment of the anaphora resolution.By the analysis of many kinds of anaphoric examples,this paper will point out that,when the anaphora resolution has some mistake,the linguistic context will restrict on anaphor.The purpose is to influence semantic connection between the antecedent and the anaphor,and make the anaphora resolution accomplish successfully. 相似文献
