摘要：Abstract Models are essential in computer-aided design, manufacturing (CAD/CAM) and concurrent engineering. They are important for object representation, manipulation, and data communication. With fast and explicit availability of 3D object coordinates, range imaging is increasingly used in various engineering applications. We use a laser scanner to digitize object geometry. Model understanding of the digitized range object is therefore a fundamental task in this work. Features are of paramount importance in design and manufacturing contexts, as they are a natural choice for capturing and describing the identity of individual objects, as well as establishing relationships between certain objects. We propose a multi-stage approach to understand range objects. A geometry-based method is developed to evaluate the curvature features of objects in range images. The mapping of the curvature signs is then used to initiate a fuzzy partitioning process in order to extract the quadratic shells. This is followed by a process of qualitative feature identification using a geometric invariance based method. The extracted feature information can be applied to rectify the error introduced during the processes of object scanning and numerical calculation and also can be served to enhance various processes in rapid prototyping application including optimized model re-orientation, etc.

摘要：A method-mix for intercultural user interface design (IUID) is explained and exemplified by application examples based on a hybrid approach covering cultural contexts in human-computer interaction (HCI) design using a model of culturally influenced HCI. Cultural influence on HCI is described using cultural variables for user interface design. Assumptions and empirical results regarding the influence of culture on HCI, considering the path of the information processing and the interaction style between Chinese and German users are explained based on cultural models. Subsequent indicators represent the relationship between culture and HCI (culturally imprinted by the user). Correlations adopted theoretically between cultural dimensions and variables for HCI design were investigated. These correlations represent relevant constituents of a model for culturally influenced HCI. Considerations applying this model and evidence for the proper application of the IUID method-mix are presented elucidating why and how cultural aspects play a role in HCI design and usability/UX engineering. The IUID method-mix serves to inspire HCI engineers in the requirement analysis phase as well as HCI designers in the design phase. The readers are thereby sensitized to the challenges of intercultural usability/UX engineering and intercultural HCI design and will be equipped with methodological knowledge relevant to the derivation of design recommendations for user interface design for and in their desired cultural contexts. Finally, implications for practitioners are shown, including HCI style scores and practical design recommendations, to prognosticate the effort and the expenditures for considering the cultural context in IUID.

摘要：Automatically mapping a requirement specification to design model in Software Engineering is an open complex problem. Existing methods use a complex manual process that use the knowledge from the requirement specification/modeling and the design, and try to find a good match between them. The key task done by designers is to convert a natural language based requirement specification (or corresponding UML based representation) into a predominantly computer language based design model—thus the process is very complex as there is a very large gap between our natural language and computer language. Moreover, this is not just a simple language conversion, but rather a complex knowledge conversion that can lead to meaningful design implementation. In this paper, we describe an automated method to map Requirement Model to Design Model and thus automate/partially automate the Structured Design (SD) process. We believe, this is the first logical step in mapping a more complex requirement specification to design model. We call it IRTDM (Intelligent Agent based requirement model to design model mapping). The main theme of IRTDM is to use some AI (Artificial Intelligence) based algorithms, semantic representation using Ontology or Predicate Logic, design structures using some well known design framework and Machine Learning algorithms for learning over time. Semantics help convert natural language based requirement specification (and associated UML representation) into high level design model followed by mapping to design structures. AI method can also be used to convert high level design structures into lower level design which then can be refined further by some manual and/or semi automated process. We emphasize that automation is one of the key ways to minimize the software cost, and is very important for all, especially, for the “Design for the Bottom 90% People” or BOP (Base of the Pyramid People).

摘要：三、对音乐本体意义的阐释所谓本体,源于拉丁文on(存在、有、是)和ontos(存在物)",指事物的终极存在,也就是事物的内部属性、质的规定性和本原"[12]。本体论(ontology)在西方哲学中,指关于存在及其本质和规律的学说。17世纪德国经院学者郭克兰纽(1547-1628)在其著作中第一次使用了"本体论"一词,表示研究(onto)的一般学问,并将其作为形而上学的同义词。

摘要：本刊视读者的反馈意见为生命线。宋志平和钱妮娜来信的字里行间透出了对本刊的挚爱。我们挚爱眼睛,就不容眼里飞入一粒沙子！宋志平等读者来信来email提出的关于本刊第8期出现的翻译问题,本刊在感激之余,也深感遗憾和愧疚！本期在“翻译茶座”专栏刊登了辛宇的文章“second name指姓还是名?”对该译文提出了批评。读者的反应再次告诉我们,对每一篇发表的稿件都应严格审核,即使是对我们比较信任的老作者的稿件,也绝不能例外。本刊的校对工作,也将进一步加强。 另外,本刊连续三期,用较多篇幅刊登了本刊主编的“治学一席谈”(治学捷径Ⅰ—Ⅲ),文章发表之后,收到大量读者的来信和email,他们对这样的文章喜闻乐见,觉得“一下子拉近了自己和《科技英语学习》的距离”,觉得“做学问原来也充满了哲理和艺术”,觉得“听君一席言,胜读几册书”,觉得“国庆长假的第一乐事乃读戎刿之文也”！等等。武汉理工大学钱妮娜来信,用流畅而又准确的英语表达了她读“治学捷径”的心情和心得。 今后,本刊将邀请别的教授向读者敞开心扉,“面授”
