Many antiquated or legacy systems are still in operation today because they are critical to the organizations continued operations or are prohibitively expensive to replace. This book guides practitioners in managing the process of legacy system evolution. The author introduces a comprehensive method for managing a software evolution project, from its conception to the deployment of the resulting system. The book helps managers answer two critical decisions: What is the best way to evolve a particular legacy system? and How can the legacy system be migrated to a selected target architecture?

Science demands that all theory must be checked by experiment. Richard Feyn man, Nobel Laureate in physics (1965), reminds us in a wonderful quote that "The test of all knowledge is experiment. Experiment is the sole judge of sci entific truth. " 1 It is because nonlinear physics can be so profoundly counter intuitive that these laboratory investigations are so important. This manual is designed to be used with the text Nonlinear Physics with Maple for Scientists and Engineers. Understanding is enhanced when experiments are used to check so please attempt as many of the activities as you can. As you perform theory, these activities, we hope that you will be amazed and startled by strange behav ior, intrigued and terrorized by new ideas, and be able to amaze your friends as you relate your strange sightings Remember that imagination is just as impor tant as knowledge, so exercise yours whenever possible. But please be careful, as nonlinear activities can be addicting, can provide fond memories, and can awaken an interest that lasts a lifetime. Although it has been said that a rose by any other name is still a rose, (with apologies to Shakespeare) the authors of this laboratory manual have, in an endeavor to encourage the use of these nonlinear investigations, called them experimental activities rather than experiments. A number of design innovations have been introduced: A."

Es war mir eine grosse Freude, zusammen mit meinem Freund Colin Hood dieses Buch zu schreiben. Seine reichhaltigen Erfahrungen aus sehr vielen unterschiedlichen Industriezweigen, auf unterschied- chen Ebenen und in verschiedenen Entwicklungsabteilungen geben tiefe Einblicke in die unterschiedlichsten Unternehmenskulturen. Um das oft als sehr trocken angesehene Thema des Requirements Management und Engineerings spannend zu gestalten, haben wir Teile dieser Erfahrung an Hand von Stories von Colin Hood in die einzelnen Kapitel des Buches eingestreut. Diese Stories sind gr- tenteils authentisch, manchmal auch aus mehreren Gegebenheiten konstruiert. Der Begriff Requirements Management begleitet mein Berufs- ben nun seit 1991. Damals, als Informatiker der bereits einige Erf- rung in der Softwareentwicklung und Durchfuhrung von Softwa- projekten sammeln konnte, war mir bereits bei der ersten Beschaf- gung mit diesem Thema klar, dass hier einiges an Potential brach liegt. In dieser Zeit Information uber Requirements Management und Engineering zu bekommen, war nicht ganz einfach; Bucher daruber gab es kaum. Bei Organisationen wie IEE, IEEE und NCSE (aus der dann spater die INCOSE entstand) beschaftigten sich aber bereits Arbeitsgruppen mit Requirements Management oder mit Requirements Engineering (wir machen uns im Verlauf des Buches noch Gedanken zu diesen und ahnlichen Begriffen)."

OpenStep is a landmark development. It brings together many of the features software developers have been seeking in a software development environment: true object orientation, open systems architecture, interoperability, robust class libraries, and the ability to separate the user interface from business logic in a way that allows applications to be deployed on multiple platforms, and over the World Wide Web. This book is an in-depth introduction to OpenStep and its use in developing business applications. The authors are experienced OpenStep developers and bring to the book the understanding that the process of object-oriented development is just as important as understanding the technology of object-oriented development. As a result, every potential OpenStep developer will find much of interest in this book.

The Maple ODE Lab Book is intended to provide a thorough introduc tion to using symbolic computation software to model, solve, explore, and visualize ordinary differential equations. It is best used as a supplement to existing texts (see the bibliography for some of our recommended texts). Maple was chosen as our software package because of its ease-of-use, affordability, and popularity at many universities and colleges around the world. The version being used is Maple V Release 4. If you have a previous release of Maple, some of the commands shown in this lab book will work differently (or not at all), but the basic groundwork for solving ODEs hasn't changed. Speak to your system administrator about upgrading to Release 4, or contact: Waterloo Maple Inc. 450 Phillip Street Waterloo, Ontario CANADA N2L 5J2 Phone: (519) 747-2373 FAX: (519) 747-5284 E-mail: [email protected] WWW: http: //www.maplesoft.com 1 2 Chapter 1. Introduction How This Lab Book Is Organized Each subsequent chapter of this lab book contains information and ex amples of how to apply Maple to various elements of ordinary differential equations. It is suggested that you read the chapters with your computer on and Maple V Release 4 running. You can then execute many of the com mands yourself and experiment by changing various parameters and/or initial conditions, observing the corresponding changes in the results."

This book constitutes the refereed proceedings of the 8th International Conference on Computer Aided Verification, CAV '96, held in New Brunswick, NJ, USA, in July/August 1996 as part of the FLoC '96 federated conference.
The volume presents 32 revised full research contributions selected from a total of 93 submissions; also included are 20 carefully selected descriptions of tools and case studies. The set of papers reports the state-of-the-art of the theory and practice of computer assisted formal analysis methods for software and hardware systems; a certain emphasis is placed on verification tools and the algorithms and techniques that are needed for their implementation.

lfimplementing systematic reuse is risky, not doing it is even more risky. Trying systematic reuse unsuccessfully can cost precious time and resources and may make management sceptical of trying it again. But if your competitors do it successfully and you do not, you may lose market share and possibly an entire market. W. B. Frakes and S. Isoda, 1994 Software companies today are faced with new and more challenging market pressures. In response to this challenge, they have to reduce the time-to-market with new or enhanced products, increase the diversity of products available to the customers, and enhance the standardisation and interoperability of the products. At the same time, many companies carry the burden of large legacy systems, that have become too expensive to maintain and cannot sustain the demands of the marketing department for alterations, leading to business opportunities being lost [BEN95]. However the systems are very valuable and cannot be simply replaced because of the costs that such an operation entails. Simply replacing them may be too expensive because of the huge volumes of on-line data that must be converted, among other reasons.

The advent of relatively inexpensive but powerful computers is af fecting practically all aspects of our lives, but some of the greatest influence is being felt in the physical sciences. However, university curricula and teaching methods have responded somewhat cautiously, having only recently come to terms with the now omnipresent calcula tor. While many instructors at first feared that the widespread use of pocket calculators would lead to generations of students who could not multiply or perhaps even add, few now seriously lament the disappear ance of slide rules, logarithm tables, and the often error-bound tedium that such tools of the trade demand. Time that used to be spent on the use of logarithm tables and manual square-root extraction can be prof itably turned to earlier studies of calculus or computer programming. Now that the calculator has been accepted into the classroom, we face a computer-software revolution which promises to be considerably more profound. Modern textbooks in the physical sciences routinely assume their readers have access not only to calculators, but often to home or even mainframe computers as well, and the problems teachers discuss and assign students can be more complex and often more realistic than in the days of only pad and pencil computations. As less effort is spent on numerical computation, more can be devoted to conceptual under standing and to applications of the increasingly sophisticated mathe matical methods needed for a real appreciation of recent advances in the discipline."

The Maple Summer Workshop and Symposium, MSWS '94, reflects the growing commu nity of Maple users around the world. This volume contains the contributed papers. A careful inspection of author affiliations will reveal that they come from North America, Europe, and Australia. In fact, fifteen come from the United States, two from Canada, one from Australia, and nine come from Europe. Of European papers, two are from Ger many, two are from the Netherlands, two are from Spain, and one each is from Switzerland, Denmark, and the United Kingdom. More important than the geographical diversity is the intellectual range of the contributions. We begin to see in this collection of works papers in which Maple is used in an increasingly flexible way. For example, there is an application in computer science that uses Maple as a tool to create a new utility. There is an application in abstract algebra where Maple has been used to create new functionalities for computing in a rational function field. There are applications to geometrical optics, digital signal processing, and experimental design."

In practical management, a policy maker often has to make a choice from among various alternatives. Quite often, there are several conflicting criteria to take into account. In addition, some criteria are non-numeric: they can only be expressed as `more' or `less'. The QUALIFLEX method for multicriteria analysis has been developed by the Netherlands Economic Institute to handle such problems. It is designed for use at all levels of decision making, both in the public and private sector. QUALIFLEX has the following features: simultaneous use of qualitative and quantitative data; full flexibility with regard to alternatives and criteria; scores in their own, natural measures; different weighting options for the criteria; sensitivity analysis of the relative weights of the criteria; the result is an optimal ranking of the alternatives. GBP/LISTGBP The Decision Support System QUALIFLEX 2.3 is a fully revised version of the program Micro-Qualiflex. The main improvements are: now user friendly and menu driven; graphical presentation; reversibility and data editing; optional input from (dBase) files.

This volume contains the proceedings of the Second International Symposium on Theoretical Aspects of Computer Science, held at Tohoku University, Japan in April 1994. This top-level international symposium on theoretical computer science is devoted to theoretical aspects of programming, programming languages and system, and parallel and distributed computation. The papers in the volume are grouped into sessions on: lambda calculus and programming; automated deduction; functional programming; objects and assignments; concurrency; term rewriting and process equivalence; type theory and programming; algebra, categories and linear logic; and subtyping, intersection and union types. The volume also includes seven invited talks and two open lectures.

Modern software tools like Maple have the potential to alter radically the way mathematics is taught, learned, and done. Bringing such tools into the classroom during lectures, assignments, and examinations means that new ways oflooking at mathematics can becomepermanent fixtures ofthe curriculum. It is universal access that will make a software-based approach to mathematics become the norm. In 1988, with NSF funding under an III grant, I had the opportunity to bring Maple into the calculus classroom at Rose-Hulman Institute of Technology. Since then a new curriculum based on the availability ofcomputer algebra systems has evolved at RHIT and in my own courses. This volume contains a record of some of the insights gained into pedagogy using Maple in calculus. The activities and ideas captured in these Maple worksheets reflect concepts in calculus imple mented in Maple. There is an overt message to the reader that carries with it a side effect. However, it is possible that for one reader the side effect is the message and the message is the side effect I had intended to put before my audience examples extracted from my Maple based curriculum to entice a wider acceptance ofthe benefits of making a computer algebra system become the basis of a revised calculus syllabus. By examples I had hoped to demonstrate the "rightness" of using software tools for teaching and learning calculus."

This book shows how blockchain technology can transform the Internet, connecting global businesses in disruptive ways. It offers a comprehensive and multi-faceted examination of the potential of distributed ledger technology (DLT) from a new perspective: as an enabler of the Internet of Value (IoV). The authors discuss applications of blockchain technology to the financial services domain, e.g. in real estate, insurance and the emerging Decentralised Finance (DeFi) movement. They also cover applications to the media and e-commerce domains. DLT's impacts on the circular economy, marketplace, Internet of Things (IoT) and oracle business models are also investigated. In closing, the book provides outlooks on the evolution of DLT, as well as the systemic governance and privacy risks of the IoV. The book is intended for a broad readership, including students, researchers and industry practitioners.

Modern business relies heavily on information technology. This book presents a new "always-on" business model for the digital age, one based on three interrelated components: a business model, an IT capability model, and an always-on information system model. In addition, it develops an implementation framework for the new model by identifying business-critical continuous computing information technologies as implementation drivers. The model proposed in this book reveals the critical role of business continuity management in ensuring business continuity even when operations are unaffected by any disasters. Using empirical survey data, PLS-SEM (Partial Least Squares - Structural Equation Modeling) combined with mediation analysis are used to test the model and hypotheses. The book is chiefly intended for students in Business Administration/Management degree programs and business leaders whose work involves addressing issues such as organizational performance, IT capability, enterprise information systems, IT management, business continuity management, disaster recovery management, risk management, IT auditing, and compliance.

This volume constitutes the proceedings of the First International Symposiumorganized by the Japan Society for Software Science and Technology. The symposium was held in Kanazawa, Japan, November 4-6, 1993 and attracted many researchers from academia and industry as well as ambitioned practitioners. Object technologies, in particular object-oriented programming, object-oriented databases, and software object bases, currently attract much attention and hold a great promise of future research and development in diverse areas of advanced software. The volume contains besides 6 invited presentations by renown researchers and 25 contributed papers carefully selected by an internationalprogram committee from a total of 92 submissions.

This volume comprises the proceedings of the Eleventh International Conference on the Entity-Relationship Approach held in Karlsruhe, Germany, October 7-9, 1992. It contains the full versions of all the 22 accepted papers selected from in total 64 submissions; in addition, the two invited talks by Scheer and by Tsichritzis and others are represented asfull papers and the two other invited speakers contribute extended abstracts. All the contributions describe original research related to theoretical or practical aspects of the Entity-Relationship Approach, reflecting the trend of recent years in a wide range of database research activities. In particular, the topics database design aspects, object-orientation, integrity constraints, query languages, knowledge-based techniques, and development of new applications are addressed.

Object-orientation and the need for multi-paradigmatic systems constitute a challenge for researchers, practitioners and instructors. Presentations at the OCG/NJSZT joint conference in Klagenfurt, Austria, in September 1992 addressed these issues. The proceedings comprise such topics as: project management, artificial intelligence - modelling aspects, artificial intelligence - tool building aspects, language features, object-orientied software development, the challenge of coping with complexity, methodology, and experience, software engineering education, science policy, etc.

Intelligent Collaborative e-Learning Systems and Applications is a major research theme in CSCL and CSCW research community. It comprises a variety of research topics that focus on developing systems that are more powerful and flexible and also more adaptable to the learning process and thus provide better answers to the paradigmatic principles of on-line collaborative learning and work. The chapters collected in this book provide new insights, findings and approaches both on the analysis and the development of more powerful e-collaboration settings. Researchers will find in this book the latest trends in these research topics. On the other hand, academics will find practical insights on how to use conceptual and experimental approaches in their daily tasks. Finally, developers from CSCL community can be inspired and put in practice the proposed models and evaluate them for the specific purposes of their own work and context.

After many years of teaching circuit theory and analogue electronic circuits the author believes that for most students the main path to obtaining a good understanding of the principles involved, as measured by their ability to apply them in a correct and intelligent manner, is through problem solving and design exercises. In an ideal world the student would be able to construct the circuit being analysed or designed, and so directly test the calculated or pre dicted results. Indeed, experience leads to the conclusion that typical students like to see their own circuits perform as intended, with a con sequent increase in motivation. At present, however, time and facility constraints mean that most of this work is of the pencil and paper variety, students having few opportunities to see the consequences of their efforts in a practical situation. At best they have to accept sample solutions or simply num erical answers. This path can seem tedious to all but the most motivated of students, so an alternative which can provide many of the benefits of direct circuit testing within the time and resources available is of im mediate interest. This is where the MINNIE and HSpice simulation package can assist the undergraduate teaching activity."
