Presenting a reference model architecture for the design of intelligent systems

Engineering of Mind presents the foundations for a computational theory of intelligence. It discusses the main streams of investigation that will eventually converge in a scientific theory of mind and proposes an avenue of research that might best lead to the development of truly intelligent systems.

This book presents a model of the brain as a hierarchy of massive parallel computational modules and data structures interconnected by information pathways. Using this as the basic model on which intelligent systems should be based, the authors propose a reference model architecture that accommodates concepts from artificial intelligence, control theory, image understanding, signal processing, and decision theory. Algorithms, procedures, and data embedded within this architecture would enable the analysis of situations, the formulation of plans, the choice of behaviors, and the computation of uncertainties. The computational power to implement the model can be achieved in practical systems in the foreseeable future through hierarchical and parallel distribution of computational tasks.

The authors’ reference model architecture is expressed in terms of the Real-time Control System (RCS) that has been developed primarily at the National Institute of Standards and Technology. Suitable for engineers, computer scientists, researchers, and students, Engineering of Mind blends current theory and practice to achieve a coherent model for the design of intelligent systems.

This book presents simple, elegant methods for dealing, both in theory and in application, with a variety of problems that have formulations in terms of flows in capacity-constrained networks. Since the theoretical considerations lead in all cases to computationally efficient solution procedures, the hook provides a common meeting ground for persons interested in operations research, industrial and communications engineering, or combinatorial mathematics.

Semantic Web services promise to automate tasks such as discovery, mediation, selection, composition, and invocation of services, enabling fully flexible automated e-business. Their usage, however, still requires a significant amount of human intervention due to the lack of support for a machine-processable description. In this book, Jos de Bruijn and his coauthors lay the foundations for understanding the requirements that shape the description of the various aspects related to Semantic Web services, such as the static background knowledge in the form of ontologies, the functional description of the service, and the behavioral description of the service. They introduce the Web Service Modeling Language (WSML), which provides means for describing the functionality and behavior of Web services, as well as the underlying business knowledge, in the form of ontologies, with a conceptual grounding in the Web Service Modeling Ontology. Academic and industrial researchers as well as professionals will find a comprehensive overview of the concepts and challenges in the area of Semantic Web services, the Web Services Modeling Language and its relation to the Web Services Modeling Ontology, and an in-depth treatment of both enabling technologies and theoretical foundations.

According to the W3C Semantic Web Activity [1]: The Semantic Web provides a common framework that allows data to be shared and reused across appli- tion, enterprise, and community boundaries. This statement clearly explains that the Semantic Web is about data sharing. Currently, the Web uses hyperlinks to connect Web pages. The Semantic Web goes beyond that and focuses on data and envisions the creation of the web of data. On the Semantic Web, anyone can say anything about any resource on the Web. This is fully based on the concept of semantic - notations, where each resource on the Web can have an assigned meaning. This is done through the use of ontologies as a formal and explicit representation of domain concepts and their relationships [2]. Ontologies are formally based on description logics. This enables agents and applications to reason over the data when searching the Web, which has not previously been possible. Web 2. 0 has gradually evolved from letting the Web users play a more active role. Unlike the initial version of the Web, where the users mainly "consumed" content, users are now offered easy-to-use services for content production and publication. Mashups, blogs, wikis, feeds, interface remixes, and social networking/tagging s- tems are examples of these well-known services. The success and wide adoption of Web 2. 0 was in its reliance on social interactions as an inevitable characteristic of the use and life of the Web. In particular, Web 2.

Hypermedia & the Web An Engineering Approach David Lowe, University of Technology, Sydney, Australia Wendy Hall, University of Southampton, UK The rich online world offered through the Web is marred by the chaos which underlies it. At the very early stages of understanding how to harness the power of this new medium, electronic document creators, managers and researchers often spend time on technology innovations at the expense of adopting the sound engineering principles which have paid such dividends in the software industry. Hypermedio & the Web approaches interactive information (concentrating on hypertext documents) as a structure requiring management, quantification and documentation. From analysing the purpose for which a website, CD-ROM or online archive is created, assessing the characteristics and resources needed for the process of building each one, to the assessment of the end product itself, this book attempts to carve out features that are essential to the successful structuring of information in an electronic environment. This is an ambitious book charting an emerging discipline. It is an essential tool to help developers and educators shape and maintain useful and relevant electronic information. 'Hypermedia Engineering hasn't produced many tangible benefits in real-life situations, because very few people practise it. That's why the book is needed.' David Barron, Southampton University 'This book is interesting and excellently fulfills a current need [by] providing an exhaustive and up-to-date vision of the hypermedia field.' Fabio Vitali, University of Bologna 'The strength of this book is its breadth - it covers many of the issues in hypermedia with examples from thetechnical to the managerial. Students could use these as starting points when designing or evaluating hypermedia systems.' David Sharp, Imperial College of Science and Technology 'Information systems developers and managers should find this a helpful guide for developing hypermedia applications.'

Durch die Weiterentwicklung der kommunikationstechnischen Infrastruktur ergeben sich neue Freiraume bei der Distribuierung von Informations- und Kommunikationssystemen (IKS). Das Buch stellt ein computergestutztes Entscheidungsmodell zur Bestimmung des optimalen Distribuierungsgrades von IKS vor und dokumentiert die Entwicklung eines Prototyps. Die Diskussion der Rahmenbedingungen baut auf einem kybernetischen Unternehmensmodell auf, das es ermoeglicht, die Lebensfahigkeit eines Systems in seiner Umwelt zu untersuchen. Die geforderte Eigenschaft der Rekursivitat des Modells fuhrt zu dem Schluss, dass auch das IKS in einem Unternehmen hinsichtlich seiner Lebensfahigkeit beschrieben werden kann. In der Folge wird die Organisation unter einem strukturellen Aspekt untersucht. Dabei wird die Dimension der Distribuierung und das Distribuierungskontinuum beschrieben. Der Prozess der strategischen Unternehmensplanung, die Ableitung von Informatikprojekten (Projektportfolio) und Informatikzielen und die darin begrundeten Einflusse auf eine Distribuierungsentscheidung bilden den Gegenstand weiterer Untersuchungen. Als dritte Rahmenbedingung wird dann die Bedeutung der Entwicklung von Normen und Standards diskutiert. Dabei steht weniger der technische Aspekt im Vordergrund. Vielmehr werden die Anforderungen untersucht, denen ein IKS genugen muss, wenn der Distributionsgrad nicht von den technischen Moeglichkeiten sondern von anderen Faktoren bestimmt wird. Der zweite Teil der Arbeit beinhaltet eine Beschreibung der logischen Struktur des Prototyps, der Entwicklungsumgebung, der zugrundeliegenden Datenstruktur und der Benutzerschnittstelle anhand einer Beispiel-Konsultation.

A guide to applying software design principles and coding practices to VHDL to improve the readability, maintainability, and quality of VHDL code. This book addresses an often-neglected aspect of the creation of VHDL designs. A VHDL description is also source code, and VHDL designers can use the best practices of software development to write high-quality code and to organize it in a design. This book presents this unique set of skills, teaching VHDL designers of all experience levels how to apply the best design principles and coding practices from the software world to the world of hardware. The concepts introduced here will help readers write code that is easier to understand and more likely to be correct, with improved readability, maintainability, and overall quality. After a brief review of VHDL, the book presents fundamental design principles for writing code, discussing such topics as design, quality, architecture, modularity, abstraction, and hierarchy. Building on these concepts, the book then introduces and provides recommendations for each basic element of VHDL code, including statements, design units, types, data objects, and subprograms. The book covers naming data objects and functions, commenting the source code, and visually presenting the code on the screen. All recommendations are supported by detailed rationales. Finally, the book explores two uses of VHDL: synthesis and testbenches. It examines the key characteristics of code intended for synthesis (distinguishing it from code meant for simulation) and then demonstrates the design and implementation of testbenches with a series of examples that verify different kinds of models, including combinational, sequential, and FSM code. Examples from the book are also available on a companion website, enabling the reader to experiment with the complete source code.

Data is an intrinsic part of our daily lives. Everything we do is a data point. Many of these data points are recorded with the intent to help us lead more efficient lives. We have apps that track our workouts, sleep, food intake, and personal finance. We use the data to make changes to our lives based on goals we have set for ourselves. Businesses use vast collections of data to determine strategy and marketing. Data scientists take data, analyze it, and create models to help solve problems. You may have heard of companies having data management teams or chief information officers (CIOs) or chief data officers (CDOs), etc. They are all people who work with data, but their function is more related to vetting data and preparing it for use by data scientists. The jump from personal data usage for self-betterment to mass data analysis for business process improvement often feels bigger to us than it is. In turn, we often think big data analysis requires tools held only by advanced degree holders. Although advanced degrees are certainly valuable, this book illustrates how it is not a requirement to adequately run a data science project. Because we are all already data users, with some simple strategies and exposure to basic analytical software programs, anyone who has the proper tools and determination can solve data science problems. The process presented in this book will help empower individuals to work on and solve data-related challenges. The goal of this book is to provide a step-by-step guide to the data science process so that you can feel confident in leading your own data science project. To aid with clarity and understanding, the author presents a fictional restaurant chain to use as a case study, illustrating how the various topics discussed can be applied. Essentially, this book helps traditional businesspeople solve data-related problems on their own without any hesitation or fear. The powerful methods are presented in the form of conversations, examples, and case studies. The conversational style is engaging and provides clarity.
