The purpose of the present work is to introduce and investigate a new class of sets called (i, j)-Ps– open sets, and use this class to define and study new concepts in bitopological spaces such as continuity and separation axioms. At the beginning of this work, we define the class of (i, j)-Ps– open sets which contained in the class of j-preopen sets and also contained in the class of (i, j)-gp– open sets. It is shown that the family of (i, j)-Ps– open sets form a supratopology on X. We prove that the family of (i, j)-Ps– open sets and the family of j-preopen sets are identical when (X, ?i) are semi-T1-spaces. Finally, some separation axioms such as T0, T1 and T2 spaces are defined in bitopological spaces, also R0, R1 and Urysohn spaces are defined and the relation between them are found by using the new type of graph functions called (i, j)-Ps – closed graph. It is noticed that if (X, ?1, ?2) is (i, j)-Ps–Tk, then it is (i, j)-Ps–Tk-1, for k=1, 2. It is proved that a bitopological space (X, ?1, ?2) is (i, j)-Ps–T1 if the (i, j)-Ps– derived set of every point of X is empty.

The aim of this work is to introduce and study a new class of set as an extension of semi-open sets in topological spaces called the Sw-open set. We use this set to define new types of continuous functions and new types of topological spaces.It is proved that every Sw-open set is dense and both the families SwO(X) and SO(X) coincide whenever the space X is hyperconnected. The topological spaces (X, ?) and (X, ??) have the same family of Sw-open sets.The concept of Sw-compactness is introduced and we prove that a space X is Sw-compact if and only if for every somewhat preopen cover of a space X there is a finite subcover under the condition that X is strongly irresolvable.Separation axioms are defined and characterized and it is proved that the space X is Sw-T2 whenever each point of X possesses an Sw-regular subset which is an Sw-T2 subspace in X.

Introduction to Fine Topological Spaces

4929 руб.
This book describes a new concept of fine topological space. The collection of fine open sets contains all semi-open, pre-open, ?-open,?-open etc. sets which are used in defining the lighter concepts of continuity. With this wider class of fine sets the authors have defined the continuity which includes several other continuities already defined. Csaszar A. has introduced the concept of generalized topological space in 2002. A fine topological space is a special case of generalized topological space, but it may be noted that the concept of fine space is based on a topological space. The notions of several continuous functions in topological spaces and fuzzy topological spaces are widely developed which are used extensively in many practical and engineering problems. The concept of continuity and homeomorphism are used in many fields such as in Chemistry, Computer Science, Physics, Zoology, Quantum physics, Quantum mechanics etc. Now, there is a wide scope of study this concept in view of fuzzy topological space.

Zadeh (1965), introduced the basic idea of a fuzzy set as an extension of classical set theory. In 1968, Chang was the first to introduce the concept of a fuzzy topology. Kubiak and Sostak (1985) introduced the fundamental concept of a fuzzy topological structure, as an extension of both crisp topology and fuzzy topology, in the sense that not only the objects are fuzzified, but also the axiomatics. Also, Sostak gave some rules and showed how such an extension can be realized. The purpose of this book is to introduce and study some new definitions of fuzzy sets, continuous mappings and separation axioms On Fuzzy Topological Spaces In Sostak's Sence.

Cantorian Space-Time Theory

The possibility of using quantum sets in quantum mechanics was considered long ago. In this book we consider fractal Cantorian sets and emphasize the role of the empty set in physics and the crucial difference between the zero and the empty set. The quantum particle is represented by a Cantorian zero set while the quantum wave is represented by an empty Cantorian set. The new quantum entanglement theory is presented generalizing Einstein’s energy equation to an effective quantum gravity formula predicting accurately the actually measured cosmic energy content of the universe. The energy given by Einstein’s famous formula consists of two parts. The first part is the ordinary energy of the quantum particle modelled by the topology of the zero set. The second part is the dark energy of the quantum wave modelled by the topology of the empty set.

Nonstandard topoplogy is a kind of topology that is constructed by means of nonstandard analysis. In the literature, there is an abundace of books and papers that treat nostandard analysis, but, on the other hand, there are quite a few books and papers that treat nonstandard topology. This book gives a simple and comprehensive treatment of nonstandard topology. In fact, it presents to the reader most of what he/she needs to know about the subject in a simple and correlative way by mimicking the presentation of the standard topology. This simplification may help interested researchers in developing topology in the sense of nonstandard methods.

The concept of fuzzifying topologies appeared in 1980 under the name L-fuzzy topology, where L is a completely distributive complete lattice. It must be pointed out that Hoehle, Lowen, Sostak and Gerla were aware of the possibility to establish fuzzifying topology and in particular, Sostak and his students have done some interesting work in this field. In 1991–1993, Ying introduced the fuzzifying topology and elementally developed fuzzy topology from a new direction with semantic method of continuous valued logic.

Multiset is a collection of objects in which the elements are allowed to repeat. The notion of multiset relations and multiset functions are introduced and the concepts in general topology on classical sets are extended to topology on multisets. Partially ordered multisets and their chains and antichains are introduced and the decomposition theorem for partially ordered multisets is obtained. Moreover multiset topologies are generated using multiset relations and to obtain a quasi-discrete multiset topology from a symmetric multiset relation instead of an equivalence multiset relation. Rough multisets are introduced and the relationship between rough multisets and multiset topologies are investigated.

Design of Virtual Topology for Small Optical WDM Networks

There is an ever increasing need for bandwidth in the Internet and various other bandwidth hungry applications. This demand can be satisfied using optical WDM that allows the same fiber to carry many signals as long as each of these uses a different wavelength. WDM is a step towards furnishing the capabilities of the optical fiber which uses wavelength routing that is the networks ability to route a signal at intermediate nodes based on their wavelength.It has the ability to create a virtual topology upon the underlying physical topology of the network. The design of a virtual topology requires setting up of lightpaths which can traverse multiple links in the physical network and yet transmission is entirely optical without any opto-electronic conversion at the intermediate nodes.The potential of the virtual topology is dependent on the virtual topology design. The designing process is a complex problem.A designed virtual topology can be considered for various objective functions such as congestion control, delay minimization, hop length minimization, reducing the number of optical transceivers employed, minimizing the number of wavelengths utilised etc.

In this work, I have reviewed existing prediction methods for the mobility of nodes and proposed three new schemes to predict the future set of topology of the mobile network. The proposed schemes are simple, efficient, and applicable to many existing algorithms. I evaluate the presented schemes on simulated and real data obtained from the Databases and Mobile Computing Laboratory at the University of Illinois at Chicago. The results show that the schemes successfully predict the future topology of the dynamic networks with high accuracy. They also minimize the frequency of route and location updates and any associated delays. The implementation of the proposed schemes on the upper layers makes them applicable to various routing algorithms including topology based routing algorithms and geographical routing algorithms, giving them the advantage of platform independence

Gaining Insights Into Volumetric Data Visualization

6690 руб.
In recent years, topology based techniques have begun to emerge as a general framework in visualization with the increase of scientific data in size and complexity. Topology could be used to capture significant features of the data at an abstract level, enabling and facilitating data understanding in visualization. This book focuses on investigating effective uses of the contour tree, one of topological abstractions of the scalar field, in improving efficiency of volumetric data analysis. It achieves the goals by increasing the presentation of topology information in order to explore various relationships of geometrical structures. In particular, the book plays emphasis on a novel approach for automating transfer function generations in volume visualization using topology-controlled residue flow model and harmonic colors. The generated transfer functions reveal structural relationships automatically. To make this work practical, this book also deals with topology simplification. The analysis should help shed some light on the research of topology-controlled visualization. It should be especially useful to professionals in volumetric visualization and medical image analysis.

Exploiting the Fat-tree Topology for Routing and Fault-Tolerance

7890 руб.
This book focus on the fat-tree topology, which is one of the most-commonly used topologies for clusters. Our aim is to exploit its characteristics to provide fault-tolerance; and a load-balanced routing algorithm that provides a good cost/performance tradeoff. First, we focus on the fault-tolerance of the fat-tree topology. Most of the works in the literature provide fault-tolerance at the cost of adding resources to the network, either switches, links or virtual channels. On the contrary to these works, we provide the same degree of fault-tolerance without increasing the resources of the network by taking advantage of the abundant plurality of equivalent paths in the fat-tree. Next, we take the challenge of designing a deterministic routing algorithm that can compete in terms of performance with the adaptive routing algorithms that are used for the fat-tree topology. Finally, we take advantage of the particular characteristics of the proposed deterministic routing algorithm to simplify the fat-tree topology.

Reliability of power system depends on the up to date knowledge of the system state for operation and control. Shifting from large conventional production units to small and/ or renewable DG connected in the distribution network means more control and monitoring system require for the Distributed System operator caused by active generation and reactive power consumption by DG. It is technically impossible to continuously model the distribution grid in real time because of tremendous number of nodes distribution and elements system.Therefore it is interesting to explore concepts in fast and scalable topology processors for monitoring and controlling applications such as state estimation, OPF and static and dynamic stability assessment in electrical distribution network the need is evident to validate with meshed network to analyze the overall performance of the proposed methodology Decentralized Topology Inference of Electrical Distribution Networks. The topology inference processor is require minimal prior knowledge of electrical network structure by taking a series of time-stamped process measurements from each bays of each substation in the network and determine the topology.

Application of fuzzy logic to control theory became successful and revolutionary. Its applications to data analysis, artificial intelligence and computational intelligence are intensively developed. Using fuzzy theory one can provide exact representation of concepts and relations that are vague. On the theoretical side fuzzy theory is applied to a variety of mathematical fields such as analysis, algebra, topology, graph theory, optimization and many branches of operations research. The aim of this book is to enrich the theoretical development of fuzzy sets and to apply the concepts of fuzzy sets to ideals in different algebraic structures namely semigroups, gamma semigroups and subtraction semigroups. The contents of this book will encourage the learners by providing them the required basic and advanced level concepts necessary in the study of fuzzy algebraic structures. Illustrative examples are given to enhance understanding.

The WSN monitoring system is a promising technique to detect the damage of the structural health. There are many established methods have been used for computing or visualizing the building structural damage. Technical challenges affecting deployment of wireless sensor network including the range of coverage area, lifetime qualities of data, real time response, interference, reflection and optimization. The goal of this research is to develop new prototype using proposed new module and tested under real time environment for computing vibration and tilt of the building. In order to cover the entire damage region, sensor network topology is the key characteristic of sensor network. The loss of ZigBee based sensor network topology is investigated and efficient queueing method is obtained based on CBR (Constant Bit Rate) traffic and DT (Drop Tail), SFQ (Stochastic Fair Queueing) and RED (Random Early Discard) queuing mechanism using NS-2 (Network Simulator-2). After modelling ZigBee based sensor network topology, the output and queue loss of sensor network topology are computed based on different TCP mechanism in order to find out the optimal TCP method for monitoring the network.

Interference Reduction in Mobile Ad Hoc and Sensor Networks

There are still a lot of open questions in the field of MANETs and sensor networks. If a topology incurs a large interference, either many communication signals sent by nodes will collide, or the network may experience a serious delay at delivering the data for some nodes, and even consume more energy. So, we reach to the conclusion that interference imposes a potential negative impact on the performance of wireless networks. Researchers actively explored topology control (TC) approaches for such networks. The motivation of TC is to maintain the connectivity of the network, reduce the node degree and thereby reduce the interference, and reduce power consumption in the sensor nodes. To improve the network performance, designing TC algorithms with consideration of interference is imminent and necessary. Since, it leads to fewer collisions and packet retransmissions, which indirectly reduces the power consumption and extends the lifetime of the network. In this thesis, we propose a new interference-aware connected dominating set-based topology construction algorithm, namely, IACDS, a simple, distributed, interference-aware and energy-efficient TC mechanism.

This book presents a possible solution to enhance utility grid performance when unconventional loads are connected to the public network. This topology shows a combination of dc-link and magnetic-coupling structures, which allows the interconnection of multiple sources, storage devices, and loads without the penalty of extra conversion. The proposed general topology shows several possibilities to construct a multiport converter for electric vehicle applications and, due to its flexibility in structure, provides a solution to integrate a diverse class of sources and loads. In addition, the control and energy management of the converter can be implemented by a single processor. The centralized control eliminates complicated communication structures that would be necessary in the conventional topology based on separate conversion stages.
