摘要：In a competitive business landscape, large organizations such as insurance companies and banks are under high pres-sure to innovate, improvise and distinguish their products and services while continuing to reduce the time-to market for new product introductions. Traditional approaches to software reliability modeling for such software are black box-based. Bad structure or model again can lead us to lower down these non functional properties. The basic constructs of the model are objects. We will not deal about the identification of the objects, as may be referred in many books, but how to model those objects. The objective of this paper is to provide a philosophical approach, using Goal-Question-Metric paradigm, to structure or model the identified objects of software system, in better way to improve the quality of the software.

摘要：software engineering has been taught at many institutions as individual course for many years. Recently, many higher education institutions offer a BSc degree in software Engineering. software engineers are required, especially at the small enterprises, to play many roles, and sometimes simultaneously. Beside the technical and managerial skills, software engineers should have additional intellectual skills such as domain-specific abstract thinking. Therefore, software engineering curriculum should help the students to build and improve their skills to meet the labor market needs. This study aims to explore the perceptions of software engineering students on the influence of learning software modeling and design on their domain-specific abstract thinking. Also, we explore the role of the course project in improving their domain-specific abstract thinking. The study results have shown that, most of the surveyed students believe that learning and practicing modeling and design concepts contribute to their ability to think abstractly on specific domain. However, this finding is influenced by the students’ lack of the comprehension of some modeling and design aspects (e.g., generalization). We believe that, such aspects should be introduced to the students at early levels of software engineering curriculum, which certainly will improve their ability to think abstractly on specific domain.

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：全球卫星定位系统发展至今己有20余年的历史．其应用主要都是基于一个完整的、独立的系统方案，主要架构不外乎：天线、射频前端、基带处理器、中央处理单元．内存单元．晶振等，所设计出的产品多为航天用、船用及车用导航设备．由于尺寸、功耗，成本及接收敏感度等种种考虑而难以与其它个人消费类产品结合（如个人移动电话）。本文将介绍最新的技术架构，让设计人员可以仅使用射频前端芯片及相应的软件．并能与移动设备相结合的软件卫星定位方案。

摘要：在传统的产品研发流程中,虽然已经引入了各种工程辅助软件,如三维CAD软件、有限元分析软件、机构动力学分析软件和控制系统分析软件,但彼此之间仍独立作业,缺乏整体协同作业规划.机械工程师与控制工程师虽然共同设计开发一个系统,但是他们各自都需要建立一个模型,对机械系统和控制系统进行独立设计和测试,然后进行集成.这样的开发方式,一方面,由于在设计阶段机械工程师与控制工程师缺乏互动,机械系统与控制系统独立设计,因而无法确切的检验所设计的控制律是否有效合理,也无法检验控制品质的高低,如果控制对象如液压系统中作动筒的载荷工况等信息无法完全确切的计算和把握,而只能通过估计的方式得到,自然会影响设计效果;另一方面,由于后期产品测试和验证经常与原始设计不符,一旦出现问题,必须回到各自的模型中重新进行修改机械系统和控制系统,造成巨大的人力、物力浪费.

摘要：西谚有云“History travels in a circle”。今日的长江上如梭的船儿何尝不被法磬禅师的偈语所言中?其实人们若停止对“名”和“利”的追逐,社会也将失去其前进的动力。对于任何一个企业而言,如何满足其员工对于“名”和“利”的追求——换句话说——如何设计其级别制度和薪酬体系——是企业管理上的一门重大学问。而具体到软件企业中的程序员而言,到底该如何为他们评定等级——“名”,如何为他们决定薪酬——“利”?软件企业对技术人员的吸引和流动是一种博奕,如何达到更好的平衡不仅对于管理者来说意义重大,对于程序员自身来讲,抱着一种平和的心态也是必须的。本期我们就提供了两篇稿件探讨这方面的问题,相信这些专家的观点可以让各方面的读者得到启示。
