There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

From the Publisher: 
The accessible presentation of this book gives both a general view of the entire computer vision enterprise and also offers sufficient detail to be able to build useful applications. Users learn techniques that have proven to be useful by first-hand experience and a wide range of mathematical methods. A CD-ROM with every copy of the text contains source code for programming practice, color images, and illustrative movies. Comprehensive and up-to-date, this book includes essential topics that either reflect practical significance or are of theoretical importance. Topics are discussed in substantial and increasing depth. Application surveys describe numerous important application areas such as image based rendering and digital libraries. Many important algorithms broken down and illustrated in pseudo code. Appropriate for use by engineers as a comprehensive reference to the computer vision enterprise.

Theory of fuzzy integrals and its applications

Much has been written about theory and practice in the law, and the tension between practitioners and theorists. Judges do not cite theoretical articles often; they rarely "apply" theories to particular cases. These arguments are not revisited. Instead the Essay explores the working and interaction of theory and practice, practitioners and theorists. The Essay starts with a story about solving a legal issue using our intellectual tools - theory, practice, and their progenies: experience and "gut." Next the Essay elaborates on the nature of theory, practice, experience and "gut." The third part of the Essay discusses theories that are helpful to practitioners and those that are less helpful. The Essay concludes that practitioners theorize, and theorists practice. They use these intellectual tools differently because the goals and orientations of theorists and practitioners, and the constraints under which they act, differ. Theory, practice, experience and "gut" help us think, remember, decide and create. They complement each other like the two sides of the same coin: distinct but inseparable.

Industry 4.0: A Survey on Technologies, Applications and Open Research Issues

The paper deals with the development of models and algorithms for integrated planning and scheduling of functioning and modernization of complex technical objects information systems. The paper proposes a combined algorithm for the optimal distribution and assignment of heterogeneous operations in enterprise information systems (EIS) and complex technical objects, within which these operate. A distinctive feature of the proposed approach is the ability to rely on the fundamental theory of control of complex dynamic objects. This makes it possible to significantly reduce the dimension of the problem to be solved, increase the validity of decisions made and develop reference programs for the modernization of the EIS, which could not be done before. This work continues the research conducted earlier in [11, 21].

Models and Algorithms for Planning and Scheduling of Complex Objects Functioning and Modernization

The objective of the paper is to study the evolution of attitudes toward government debt over the period of human history from the Middle Ages to present day. This article is especially relevant in light of recent events. The skyrocketing government debt has recently led to the lowering of credit ratings in the USA, Greece and Italy, which may cause a significant economic downturn. To reach the established objective, the following research methods were employed: comparative analysis and synthesis, historical and logical approaches, observation and aggregation. As a result of conducted research, the history of the national debt justification was divided into five basic stages. The authors critically analyze the theory of capital erosion and demand-side economics. Detailed study of the first four stages showed that attitudes toward public debt evolved from total rejection to approval and all-round justification. However, global financial crisis indicates the transfer to the fifth stage, in which sovereign debts require reasonable restrictions and international regulation.

Integrated modelling environment for decision making support in supply chain management: conceptual approach

New approach of models and multiple-models quality evaluation is proposed. This approachis based on twofold ideas. First, when selecting an object for modeling it is reasonable to select not a really existing (designed or abstract) object but a situation in progress, that includes the objects and the subjects of the modeling (people responsible for making decisions (DM), people responsible for the substantiation of a decision (solution), experts, and people responsible for the implementation of solutions. Second, the process of modeling is here assumed as a control process of developing situation under uncertain conditions, caused by absence of information needed for forming the substantiated decisions. The descriptive and formal statement of quality control of models and multiplemodel complexesare interpreted as problems of structural-functional synthesis of a model (a multiplemodel complex) and also, selection of optimal programs of control and regulation of structural dynamics of a situation in progress (quality control of models and multiple-model complexes).The example of solving the task of poly-model finding distances from a vertex to all other vertices of a graph is proposed.
