Coordinating production across a supply chain, designing a new VLSI chip, allocating classrooms or scheduling maintenance crews at an airport are just a few examples of complex (combinatorial) problems that can be modeled as a set of decision variables whose values are subject to a set of constraints. The decision variables may be the time when production of a particular lot will start or the plane that a maintenance crew will be working on at a given time. Constraints may range from the number of students you can ?t in a given classroom to the time it takes to transfer a lot from one plant to ***,manyformsoftheseandother combinatorial problems have continued to defy conventional programming approaches. Constraint Logic programming (CLP) ?rst emerged in the mid-eighties as a programming technique with the potential of signi?cantly reducing the time it takes to develop practical solutions to many of these problems, by combining the expressiveness of languages such as Prolog with the compu- tional power of constrained search. While the roots of CLP can be traced to Monash University in Australia, it is without any doubt in Europe that this new software technology has gained the most prominence, bene?ting, among other things, from sustained funding from both industry and public R&D programs over the past dozen years. These investments have already paid o?, resulting in a number of popular commercial solutions as well as the creation of several successful European startups.

This book presents the eight tutorial lectures given at the Second International School on Advanced Functional programming, held in Olympia, WA, USA, in August 1996.;After many years of development, functional programming languages have matured to a point where they can be used for much larger applications than has been typical in the past. These tutorial notes have been written for students and professionals in software engineering who are interested in exploring beyond the elementary concepts of functional programming and in progressing towards large-scale programming and structured software.

JR is a language for concurrent programming. It is an imperative language that provides explicit mechanisms for concurrency, communication, and s- chronization. JR is an extension of the Java programming language with - ditional concurrency mechanisms based on those in the SR (Synchronizing Resources) programming language. It is suitable for writing programs for both shared- and distributed-memory applications and machines; it is, of course, also suitable for writing sequential programs. JR can be used in applications such as parallel computation, distributed systems, simulation, and many others. JR supports many “features” useful for concurrent programming. However, our goals have always been keeping the language simple and easy to learn and use. We have achieved these goals by integrating common notions, both sequ- tial and concurrent, into a few powerful mechanisms. We have implemented these mechanisms as part of a complete language to determine their feasibility and cost, to gain hands-on experience, and to provide a tool that can be used for research and teaching. The introduction to Chapter 1 expands on how JR has realized our design goals.

Program for data analysis using R and learn practical skills to make your work more efficient. This revised book explores how to automate running code and the creation of reports to share your results, as well as writing functions and packages. It includes key R 4 features such as a new color palette for charts, an enhanced reference counting system, and normalization of matrix and array types where matrix objects now formally inherit from the array class, eliminating inconsistencies.;is not designed to teach advanced R programming nor to teach the theory behind statistical procedures. Rather, it is designed to be a practical guide moving beyond merely using R; it shows you how to program in R to automate tasks.;This book will teach you how to manipulate data in modern R structures and includes connecting R to databases such as PostgreSQL, cloud services such as Amazon Web Services (AWS), and digital dashboards such as Shiny. Each chapter also includes a detailed bibliography with references to research articles and other resources that cover relevant conceptual and theoretical topics.;Working professionals, researchers, and students who are familiar with R and basic statistical techniques such as linear regression and who want to learn how to take their R coding and programming to the next level.

The 11th International Conference on Reliable Software Technologies, Ada- Europe 2006, took place in Porto, Portugal, June 5-9, 2006. It was as usual sponsored by Ada-Europe, the European federation of national Ada societies, in cooperation with ACM SIGAda. It was organized by members of the School of Engineering of the Polytechnic Institute of Porto, in collaboration with several colleagues from di?erent institutions in Europe. Following the usual style, the conference included a three-day technical p- gram, during which the papers contained in these proceedings were presented, bracketed by two tutorial days where attendants had the opportunity to catch up on a variety of topics related to the ?eld, at both introductory and advanced levels. Continuing the success achieved in the previous year, the technical p- gramalso included an industrial track, with contributions illustrating challenges facedandsolutionsencounteredbyindustrialists frombothsides ofthe Atlantic. Furthermore, the conference was accompanied by an exhibition where vendors presented their products for supporting reliable-software development.
