Spatial Data Sharing on Grid

The Internet technology has already changed the Information Society in profound ways, and will continue to do so. Nowadays many people foresee that there is a similar trajectory for the next generation of Internet - Grid Technology. As an emerging computational and networking infrastructure, Grid Computing is designed to provide pervasive, uniform and reliable access to data, computational and human resources distributed in a dynamic, heterogeneous environment. On the other hand, the development of Geographic Information System （GIS） has been highly influenced by the evolution of information technology such as the Internet, telecommunications, software and various types of computing technology. In particular, in the distributed GIS domain, the development However, due to the closed and centralized has made significant impact in the past decade. legacy of the architecture and the lack of interoperability, modularity, and flexibility, current distributed GIS still cannot fully accommodate the distributed, dynamic, heterogeneous and speedy development in network and computing environments. Hence, the development of a high performance distributed GIS system is still a challenging task.
So, the development of Grid computing technology undoubtedly provides a unique opportunity for distributed GIS, and a Grid Computing based GIS paradigm becomes inevitable. This paper proposes a new computing platform based distributed GIS framework - the Grid Geographic Information System （G^2IS）.     

Requirements model driven adaption and evolution of Internetware

Today’s software systems need to support complex business operations and processes.The development of the web-based software systems has been pushing up the limits of traditional software engineering methodologies and technologies as they are required to be used and updated almost real-time,so that users can interact and share the same applications over the internet as needed.These applications have to adapt quickly to the diversified and dynamic changing requirements in the physical,technological,economical and social environments.As a consequence,we are expecting a major paradigm shift in software engineering to reflect such changes in computing environment in order to better address the fundamental needs of organisations in this new era.Existing software technologies,such as model driven development,business process engineering,online(re-)configuration,composition and adaptation of managerial functionalities are being repurposed to reduce the time taken for software development by reusing software codes.The ability to dynamically combine contents from numerous web sites and local resources,and the ability to instantly publish services worldwide have opened up entirely new possibilities for software development.In retrospect to the ten years applied research on Internetware,we have witnessed such a paradigm shift,which brings about many changes to the developmental experience of conventional web applications.Several related technologies,such as cloud computing,service computing,cyber-physical systems and social computing,have converged to address this emerging issue with emphasis on different aspects.In this paper,we first outline the requirements that the Internetware software paradigm should meet to excel at web application adaptation;we then propose a requirement model driven method for adaptive and evolutionary applications;and we report our experiences and case studies of applying it to an enterprise information system.Our goal is to provide high-level guidelines to researchers and practitioners to meet the challenges of building adaptive industrial-strength applications with the spectrum of processes,techniques and facilities provided within the Internetware paradigm.     

Biologically inspired visual computing:the state of the art

Visual information is highly advantageous for the evolutionary success of almost all animals.This information is likewise critical for many computing tasks,and visual computing has achieved tremendous successes in numerous applications over the last 60 years or so.In that time,the development of visual computing has moved forwards with inspiration from biological mechanisms many times.In particular,deep neural networks were inspired by the hierarchical processing mechanisms that exist in the visual cortex of primate brains(including ours),and have achieved huge breakthroughs in many domainspecific visual tasks.In order to better understand biologically inspired visual computing,we will present a survey of the current work,and hope to offer some new avenues for rethinking visual computing and designing novel neural network architectures.

Preface

I am extremely pleased to have been able to organize the assembly of the set of papers contained in this special issue of the International Journal of Software and Informatics, honoring the career of Prof. Barry W. Boehm. The papers contained in this special issue were all contributed by friends, colleagues, and admirers of Prof. Boehm, and were presented during a special Symposium held in Beijing, China on April 26 and 27, 2011, under the sponsorship of the Institute of Software, Chinese Academy of Sciences and the International Journal of Software and Informatics. The range of the subjects of these papers matches the extraordinary breadth of interests and influences of Prof. Boehm and his work. The natures of the papers range from those that make very specific technical contributions to those that are conceptual and analytical, to those that are visionary. The subject matter of the papers addresses software measurement, software management, specific software development phases, and software processes, among other topics. All cite the specific influences, inspirations, and contributions of Prof. Boehm to the work, thereby serving as documented testimony to the far ranging influence that Prof. Boehm has had upon software engineering thought and software development practice. In "Measuring Agility and Architectural Integrity", a paper that focuses on measurement, a longstanding interest of Prof. Boehm''s, Walker Royce tackles the difficult issue of how to quantify agility that nevertheless does not jeopardize the structural integrity of software. Ross Jeffery''s paper, "Software Development Cost Modeling and Estimation Through a UNSW Lens", focuses on the measurement and estimation of a different software issue, namely cost, an area in which Prof. Boehm has made some of his most fundamental and long-lasting contributions (e.g. with his COCOMO models). Neil G. Siegel''s paper, "Organizing Projects Around the Mitigation of Risks Arising from System Dynamic Behavior", shows how appropriate use of software measurement can help to mitigate risk. Risk mitigation is another issue that has been a strong and central focus of Prof. Boehm and his work, as it is a core issue behind his famous Spiral Model of software development. Another set of papers addresses the ways in which Prof. Boehm and his ideas have been broadly inspirational. In my own paper, "A Process Programmer Looks at the Spiral Model: A Tribute To the Deep Insights of Barry W. Boehm", I demonstrate how Prof. Boehm, through the Spiral Model, elucidates some profound insights about the fundamental nature of software and its development. The paper suggests that the community may have only scratched the surface of the important implications that could be drawn from the ideas behind the Spiral Model. Lori A. Clarke, in her paper, "Environment Support for Improving Software Development Processes: A Vision Influenced by the Work of Barry W. Boehm", similarly indicates how papers and ideas presented by Prof. Boehm have provided inspiration and foundations for her own work in the development and integration of software analysis tools. The application of these tools to new software domains, such as process software, is further evidence of the far-reaching impact of Prof. Boehm''s work. Two papers provide further development of Prof. Boehm''s long-held interest in the importance of software and system requirements and the difficulty of eliciting them. In "Attentiveness: Design for Reactivity at Scale", Gregory S. Hartman and William L. Scherlis explore these themes. Their paper suggests that better, more complete requirements specifications might result from focusing on attentiveness, a type of requirement whose importance has been overlooked. In "On ''The Right'' Software", Dines Bjorner presents a rigorous approach to developing software and system requirements tied directly to a correspondingly rigorous approach to domain specification. Bjorner draws a strong and important parallel to Prof. Boehm''s own insights about requirements, thereby strengthening both views, and attesting to the profundity of Prof. Boehm''s views on this crucial area of software engineering. Finally, two papers take philosophical and visionary views of software engineering, each in its own way, indicating how Prof. Boehm''s ideas and work stimulated and nourished the visionary thinking. Dieter Rombach''s paper, Empirical Software Engineering Models: Can They Become the Equivalent of Physical Laws in Traditional Engineering?" suggests the possibility of developing a solid conceptual foundation for software engineering. He suggests that this more solid conceptual foundation could derive from a focus on empirical software models, an area pioneered by Prof. Boehm. In "Polyphonic Aspects of Software Process: Looking for Philosophical Foundation of Software Engineering", Kouichi Kishida''s thoughts range broadly across Western and Eastern literature and philosophy in search of the proper philosophical foundation for software engineering. Along the way Kishida touches often upon how Prof. Boehm''s ideas helped to provide guidance for his search. This paper is an eloquent treatise on how effectively grappling with deep and difficult problems, as Prof. Boehm has done, can lead to improvements in practice, the discovery of deeper issues and truths, and to stimulating the imaginations and visions of others. Ultimately, this volume can only hint and suggest at the breadth and depth of the ideas and work of our colleague, Prof. Barry W. Boehm. It is offered in the hope that the papers themselves will educate and stimulate, but also in the hope that they will also encourage the reader to follow the many references in these papers to explore in more depth the work of Prof. Boehm. I would like to thank the authors of these papers for their excellent contributions to this Special Issue of the International Journal of Software and Informatics. In addition I would like to express my sincere thanks to Prof. Ruqian Lu, the Editor-in-Chief of the International Journal of Software and Informatics, for giving me the great honor of serving as the Editor of this Special Issue. I would also like to express my very sincere thanks to Ms. Mei Fang for her outstanding leadership of the editorial work needed to prepare these papers for publication, which has allowed the publication of this volume on a very demanding schedule. Finally, on behalf of a very grateful software engineering community, I would like to thank our friend, colleague, and leader, Prof. Barry W. Boehm, for his tireless work and amazing contributions to the formation, nurturing, and maturation of our community. This Special Issue is a small, but very earnest measure of our esteem for Prof. Boehm and his work. Leon J. Osterweil
