Constraint Programming aims at solving hard combinatorial problems, with a computation time increasing in practice exponentially. The methods are today efficient enough to solve large industrial problems, in a generic framework. However, solvers are dedicated to a single variable type: integer or real. Solving mixed problems relies on ad hoc transformations. In another field, Abstract Interpretation offers tools to prove program properties, by studying an abstraction of their concrete semantics, that is, the set of possible values of the variables during an execution. Various representations for these abstractions have been proposed. They are called abstract domains. Abstract domains can mix any type of variables, and even represent relations between the variables. In this work, we define abstract domains for Constraint Programming, so as to build a generic solving method, dealing with both integer and real variables. We also study the octagons abstract domain, already defined in Abstract Interpretation. Guiding the search by the octagonal relations, we obtain good results on a continuous benchmark. We also define our solving method using Abstract Interpretation techniques, in order to include existing abstract domains. Our solver, AbSolute, is able to solve mixed problems and use relational domains. Exploits the over-approximation methods to integrate AI tools in the methods of CP Exploits the relationships captured to solve continuous problems more effectively Learn from the developers of a solver capable of handling practically all abstract domains

The Migration Conference 2017 hosted by Harokopio University, Athens from 23 to 26 August. The 5th conference in our series, the 2017 Conference was probably the largest scholarly gathering on migration with a global scope. Human mobility, border management, integration and security, diversity and minorities as well as spatial patterns, identity and economic implications have dominated the public agenda and gave an extra impetus for the study of movers and non-movers over the last decade or so. Throughout the program of the Migration Conference you will find various key thematic areas are covered in about 400 presentations by about 400 colleagues coming from all around the world from Australia to Canada, China to Mexico, South Africa to Finland. We are also proud to bring you opportunities to meet with some of the leading scholars in the field. Our line of keynote speakers include Saskia Sassen, Oded Stark, Giuseppe Sciortino, Neli Esipova, and Yüksel Pazarkaya.

The Turkish Migration Conference 2016 is the fourth event in this series, we are proud to organise and host at the University of Vienna, Austria. Perhaps given the growing number of participants and variety in scope of research and debates included at the Conference, it is now an established quality venue fostering scholarship in Turkish Migration Studies. Over the last five years, we have seen over 1000 abstracts submitted to the conference and year on year the number of accepted presentations grew. This year, the conference accommodates over 350 presentations by hundreds of academics from all around the World. The Migration Conference attracting such a healthy number of academics is a good indicator of the success and means the conference serving its purpose and offer a good opportunity for scholarly exchange and networking. Main speakers include Jeffrey Cohen, Ibrahim Sirkeci, Philip Martin, Gudrun Biffl, Karen Phalet, Samim Akgönül, and Katharine Sarikakis.

Introduction to abstract interpretation, with examples of applications to the semantics, specification, verification, and static analysis of computer programs. Formal methods are mathematically rigorous techniques for the specification, development, manipulation, and verification of safe, robust, and secure software and hardware systems. Abstract interpretation is a unifying theory of formal methods that proposes a general methodology for proving the correctness of computing systems, based on their semantics. The concepts of abstract interpretation underlie such software tools as compilers, type systems, and security protocol analyzers. This book provides an introduction to the theory and practice of abstract interpretation, offering examples of applications to semantics, specification, verification, and static analysis of programming languages with emphasis on calculational design. The book covers all necessary computer science and mathematical concepts--including most of the logic, order, linear, fixpoint, and discrete mathematics frequently used in computer science--in separate chapters before they are used in the text. Each chapter offers exercises and selected solutions. Chapter topics include syntax, parsing, trace semantics, properties and their abstraction, fixpoints and their abstractions, reachability semantics, abstract domain and abstract interpreter, specification and verification, effective fixpoint approximation, relational static analysis, and symbolic static analysis. The main applications covered include program semantics, program specification and verification, program dynamic and static analysis of numerical properties and of such symbolic properties as dataflow analysis, software model checking, pointer analysis, dependency, and typing (both for forward and backward analysis), and their combinations. Principles of Abstract Interpretation is suitable for classroom use at the graduate level and as a reference for researchers and practitioners.

A comprehensive guide to modern treatment in a complex and evolving specialty FIVE STARS from Doody's Star Ratings™ Covering the spectrum of spinal deformity that occurs between birth and 10 years, early onset scoliosis (EOS) is an evolving specialty that faces unique challenges, especially in controlling the progression of the condition while allowing the growth of the developing spine, lungs and thorax. This important book was inspired by the inaugural early onset scoliosis meeting of spine surgeons and other medical professionals in Christ Church, Oxford, UK, in September 2011. It provides a complete picture of the field today, with topics ranging from spinal development and genetics to advances in medical management to breakthrough surgical techniques that offer promising new options for young patients. Special Features Provides practical, evidence-based solutions to managing the full range of congenital, idiopathic, neuromuscular and syndromic conditions that present in early onset scoliosis Describes pioneering surgical procedures, such as non-invasive, magnetically controlled growing rod systems that reduce the number of repetitive surgeries and hospitalizations Explores such complex topics as surgical strategies for sitting comfort and features of optimal heelchair seating Details treatments and outcome measures in diverse, multi-system disorders, such as early onset neuromuscular scoliosis Highlights perioperative care and the vital role of physiotherapy in children with EOS Introduces an EOS questionnaire that establishes validated, patient-reported data for outcome assessment Recognizing the importance of the multidisciplinary team approach in effective management, Early Onset Scoliosis offers the valuable international perspective of many leaders in the field. It is essential for orthopedic and pediatric surgeons, residents and trainees, who will use the book to develop a clear understanding of what EOS is, how it is best treated, and the principles that underlie effective clinical decision-making in these complex cases.
