Computer networking: Academic development and education

This paper identifies the importance of academic networking in Lithuania and traces the development of educational resources together with the introduction of new curricula for a Computer Science modular degree programme at Kaunas University of Technology, Lithuania under support from the EC TEMPUS programme. During the three year programme, a purpose‐built computer network teaching laboratory was created to support new teaching modules which, through a modular structure, would enable students to develop a range of networking skills within existing undergraduate and postgraduate computing schemes. The project was primarily aimed at curricula development which would provide students with a basic level of knowledge sufficient to develop distributed applications software and to design and maintain data network infrastructures. A curriculum model was developed to embody both software development and technological development themes and out of this both teaching material and practical exercises have been devised. The paper reviews how this new curriculum has been integrated into the existing Computer Science scheme in Kaunas and considers the impact it has had within the institution and its importance as a pioneering initiative for Lithuania.     

Integrated distributed intelligent system for process-control system design

In process-control system design, the Computer Aided Design (CAD) techniques have evolved a new generation of design techniques. This also paves the way for implementing Computer Integrated Manufacturing Systems (CIMS). However, the key issue to accomplishing the objectives in CAD is the automation of conceptual design. This paper first introduces the fundamentals of conceptual design for process-control system design. Then, a strategy to solve the problems in conceptual design is proposed. The associated system configuration and software implementation platform for developing intelligent systems for process control system design are presented. Finally, an application case is studied.     

Two Complementary Course Sequences on the Design and Implementation of Software Products

For many students, the first chance to produce software as part of a team comes with the first work experience outside a university. The difficulties of working with others are compounded by the problems of working in a new environment and for a client with ambiguous and changing goals. Although it is difficult to approximate the "real world" accurately in an academic course, we have implemented two full-year course sequences which apparently give our students some insight into the problems they will face when they leave the university. One course requires the development and implementation of a software product by a team of undergraduates, and the other requires experienced graduate students to act as supervisors for the undergraduate projects. We describe the content and structure of these two sequences, emphasizing how they support and enhance each other. We believe other curricula would benefit from similar courses.

On the balance between theory and practice [software engineering curriculum]

Undergraduate curricula must view it as a mandate to teach students how to effectively use logic and formal methods in software design, beginning with the first programming course. Both educational and industrial-strength tools are now available to support the implementation of this idea.     

Integrated requirements engineering: a tutorial

This short tutorial introduces the fundamental activities of RE (requirements engineering) and discusses how it has evolved as a part of the software engineering process. However, rather than focusing on the established RE techniques, the author discusses how the changing nature of software engineering has led to the new challenges in RE. The author then introduces a number of new techniques that helps us to meet these challenges by integrating RE more closely with other systems implementation activities.     

软件开发技术

软件工程是一门年轻的学科,虽然软件开发模型和结构化方法等技术在70年代广为流行,但这些技术还需要进一步研究的问题,并且有些实际问题有待解决;另一方面,软件工程又是一门迅速发展更新的学科,新观点、新技术和新方法近年来层出不穷。当前,软件过程研究及企业软件开发过程改善已经成为与技术研究同等重要的课题。一个基本的共识是：软件过程的改善和软件模式的应用两方面的无缝结合将是软件工程发展的主流,同时也是解决软件危机的主要途径。

Discovering vulnerabilities in control system human-machine interface software

As educators plan for curriculum enhancement and modifications to address the net-generation of software engineers, it will be important to communicate the necessity of considering software security engineering as applications are net-enabled. This paper presents a case study where commonly accepted software security engineering principles that have been published and employed for approximately 30 years, are not often seen in an important class of application software today. That class of software is commonly referred to as control system software or supervisory control and data acquisition (SCADA) software which is being used today within critical infrastructures and being net-enabled as it is modernized. This circumstance is driven by evolution and not intention. This paper details several vulnerabilities existing in a specific software application as a case study. These vulnerabilities are a result of not following widely-accepted secure software engineering practices which should have been considered by the software engineers developing the product studied. The applicability of these lessons to the classroom are also established with examples of how they are integrated into software engineering and computer science curricula.     

Investigating reading techniques for object-oriented framework learning

The empirical study described in the paper addresses software reading for construction: how application developers obtain an understanding of a software artifact for use in new system development. The study focuses on the processes that developers would engage in when learning and using object oriented frameworks. We analyzed 15 student software development projects using both qualitative and quantitative methods to gain insight into what processes occurred during framework usage. The contribution of the study is not to test predefined hypotheses but to generate well-supported hypotheses for further investigation. The main hypotheses produced are that example based techniques are well suited to use by beginning learners, while hierarchy based techniques are not, because of a larger learning curve. Other more specific hypotheses are proposed and discussed.

A behavioral analysis and verification approach to pattern-based design composition

Integrating software components to produce large-scale software systems is an effective way to reuse experience and reduce cost. However, unexpected interactions among components when integrated into software systems are often the cause of failures. Discovering these composition errors early in the development process could lower the cost and effort in fixing them. This paper introduces a rigorous analysis approach to software design composition based on automated verification techniques. We show how to represent, instantiate and integrate design components, and how to find design composition errors using model checking techniques. We illustrate our approach with a Web-based hypermedia case study.

Metrics in the software engineering curriculum

As a recognized discipline, software engineering traces its roots back to the 1968 NATO conference where the term was first used extensively to highlight the need for an engineering approach to the development of software. In the 30 years since that first “software engineering” conference, significant attempts have been made to improve the overall effectiveness of the software development process, and thus reduce the frequency and severity of software project failures. A major part of this improvement effort has been the attempt to develop quantitative measures which can be used to more accurately describe and better understand and manage the software development life cycle. Thus, many software metrics and models have been introduced during this period. In this article, we briefly trace the history of the development of software metrics and models, and then summarize the current state of the field. For discussion purposes, this entire development period is then arbitrarily divided into an Introductory Period (1971–1985), Growth Period (1985–1997) and the Current Period (1997–?). The development of metrics during each of these periods is then related to the treatment of software metrics and models in software engineering curricula during that same period. Our conclusion is that software engineering curricula have indeed reflected the state of software engineering as the work in software metrics and models has progressed. Furthermore, software engineering curricula of the future should reflect the relatively mature state that software metrics have attained, by covering the basic concepts of metrics in appropriate core courses, and more advanced metrics topics in a specialized, elective metrics course.

     

Software engineering education: A study on conducting collaborative senior project development

Project and teamwork training is recognized as an important aspect in software engineering (SE) education. Senior projects, which often feature industrial involvement, serve the function of a ‘capstone course’ in SE curricula, by offering comprehensive training in collaborative software development. Given the characteristics of student team projects and the social aspects of software development, instructional issues in such a course must include: how to encourage teamwork, how to formalize and streamline stakeholder participation, and how to monitor students’ work, as well as sustain their desired collaborative effort throughout the development. In this paper, we present an exploratory study which highlights a particular case and introduces the meetings-flow approach. In order to investigate how this approach could contribute to the project's results, we examined its quantitative benefits in relation to the development of the project. We also conducted focus group interviews to discuss the humanistic findings and educational effects pertaining to this approach.
