It is shown an incorrectness of introduction of a class of NP-complete problems, which reason is that Cook's S.A. theorem on that the "satisfiability" problem is the universal NP-complete problem, is not true and, therefore, the issue on existence of at least one NP-complete problem remains open, that explains failures of attempts to estimate correlations between P and NP classes. Developed a universal procedure for solving a wide range of discrete optimization problems, which can be efficiently parallelized based on cyclic structures.

We know the problems of combinatorics, such as the problem of permutations, combinations, placement, represented by the corresponding formulas. But these formulas only give us the number of solutions, not the solutions themselves. There were no common standard algorithms for solving these types of problems. These types of problems with large numbers can be referred to NP problems. But with the help of Scilab program typical algorithms of such problems are revealed and solutions are given.

Stochastic programs form a class of optimization problems that have seen much attention in the last decade. As has the class of equilibrium problems which have resulted largely from the analytic treatment of Nash games. This thesis delves into some challenging areas of stochastic optimization and stochastic equilibrium programming. Our interest is in understanding properties of these problems and in developing algorithms for solving such problems. We first consider a two-period stochastic nonlinear program. In this context, we obtain new insights into the notions of feasibility and recourse for such programs and develop an algorithm based on sequential quadratic programming. The algorithm uses two quadratic programming solvers based on Benders decomposition: an inexact cut version of the L-shaped method and a trust-region method. We next consider stochastic equilibrium problems arising from Nash-Cournot competition, inspired by a Cournot bidding model for electricity markets. We first show existence and uniqueness of Nash equilibria to a wide class of stochastic quadratic games and then develop a splitting method that can be decomposed scenario-wise to compute such equilibria.

Sadhasivam Narayanan Certain Investigation on Improved PSO Algorithm for Workflow Scheduling in Cloud Computing Environments

Cloud computing is a new prototype for enterprises which can effectively assist the execution of tasks. Task scheduling is a major constraint which greatly influences the performance of cloud computing environments. The cloud service providers and consumers have different objectives and requirements. For the moment, the load and availability of the resources vary dynamically with time. Therefore, in the cloud environment scheduling resources is a complicated problem. Moreover, task scheduling algorithm is a method by which tasks are allocated or matched to data center resources. All task scheduling problems in a cloud computing environment come under the class of combinatorial optimization problems which decide searching for an optimal solution in a finite set of potential solutions. For a combinatorial optimization problem in bounded time, exact algorithms always guarantee to find an optimal solution for every finite size instance. These kinds of problems are NP-Hard in nature. Moreover, for the large scale applications, an exact algorithm needs unexpected computation time which leads to an increase in computational burden. However, the absolutely perfect scheduling algorithm does not exist, because of conflicting scheduling objectives. Therefore, to overcome this constraint heuristic algorithms are proposed. In workflow scheduling problems, search space grows exponentially with the problem size. Heuristics optimization as a search method is useful in local search to find go...

Laurent Deroussi Metaheuristics for Logistics

11500.46 руб.
This book describes the main classical combinatorial problems that can be encountered when designing a logistics network or driving a supply chain. It shows how these problems can be tackled by metaheuristics, both separately and using an integrated approach. A huge number of techniques, from the simplest to the most advanced ones, are given for helping the reader to implement efficient solutions that meet its needs. A lot of books have been written about metaheuristics (methods for solving hard optimization problems) and supply chain management (the field in which we find a huge number of combinatorial optimization problems) in the last decades. So, the main reason of this book is to describe how these methods can be implemented for this class of problems.

Skeletal Class III malocclusion may be characterized by a prognathic mandible , retrognathic maxilla and / or a combination of the two. This sagittal dysmorphia is further magnified as it encompasses vertical and transverse problems which get aggravated most often with the fourth dimension of time. Longitudinal growth studies conducted by numerous researchers in different parts of the world has established the fact that the morphologic pattern of skeletal Class III is established early in life and maintained thereafter. Once established, the annual growth increments are quite similar to that of Class I individuals. Meanwhile, the dentoalveolar disharmony is aggravated and becomes more severe during this period.

Propositional logic allows for description and then solving of a significant class of constraint satisfaction problems, namely those that require that thedomains of variables are finite.As such, propositional logic finds applications in describing problems stemmingfrom computer science, computer engineering and combinatorial optimization.But logic goes beyond just providing descriptive means - it is supported bymechanisms for computation of answers.At present there is a class of software systems, SAT solvers, that allow(given enough of resources) for solving problems expressed in propositionallogic.This book studies syntax, semantics, and algorithms for finding solutions ofproblems expressible in propositional logic. It is addressed to individuals whowant to understand the principles on which SAT solvers are based and gain adeeper understanding of techniques used in logic-based solving.

Document from the year 2016 in the subject Sociology - Social System, Social Structure, Class, Social Stratification, University of Poznan (Institute of Sociology), language: English, abstract: The book tests the double hypothesis of the death of the middle class. Using U.S. and other developed and developing countries' materials, it seeks to answer whether the popular thesis on its demise is true, and second, it shows it is true in a conceptual sense, viz. , the term in question is a misnomer, referring to a stratum rather than a class. In the course of those investigations other key questions are examined, such as an all-important issue of socio-economic inequality: both in national and world context. The study is underpinned by an original conceptual framework encompassing social class and estate theories and ownership theory. This makes it possible to criticise many other approaches to the problems analysed. For instance, a critique of a well-known book by the French economist Th. Picketty has been undertaken, showing its numerous flaws. In addition, the analysis of the middle class concept demonstrates its defects manifest in its various definitions and usages.

New Approaches to Classes and Concepts

Classifying objects --- thus collecting them into classes --- is anoperation both fundamental and common in everyday life as well as inscientific endeavours. Logic, philosophy, mathematics and computerscience analyse this activity by means of such notions as `class',`set', and `type'. Furthermore, according to the so-called ``logical(or naive) conception of classes", these notions are related to thenotion `concept' in that classes are considered `extensions' ofconcepts. This relationship, however, is a delicate one --- as wehave learned from the paradoxes of class theory. The contributions tothis volume shed new light both on concepts and classes and theirdelicate relationship. New and original approaches to these issues(e.g., map theory, epsilon-sets, intensional type theory, AFA settheory) are presented and discussed in the broader context of theirapplication to problems from informatics and linguistics. The focus ison such matters as unrestrictive comprehension, extensionality, therelationship between the notions of concept, class and extension, andon unfounded (circular and infinitely descending) patterns ofelementhood. These and related problems have always played a role inthe development of set theory and have always delivered motivation forthe development of unorthodox views and theories. This is alsodemonstrated in this volume by contributions dealing with the historyof Zermelo's axiomatization of set theory and Ackermann's class theory...

Singh Pushpinder Ranking Approach to Solve Linear Programming Problems with Fuzzy Sets

8927 руб.
Linear programming is one of the most frequently applied operations research techniques. The classical tool for solving the linear programming problem in practice is the class of simplex algorithm which was proposed and developed by Dantzig. A lot of real world decision problems are described by linear programming models and sometimes it is necessary to formulate them with elements of imprecision or uncertainty. This imprecise nature has long been studied with the help of the probability theory. However, the probability theory might not provide the correct interpretation to solve some practical decision making problems. In these cases, the fuzzy set theory might be more helpful. In this book, the limitations and shortcomings of existing methods for solving linear programming problems with fuzzy sets are pointed out. Some new ranking approaches for the ordering of fuzzy sets and vague sets are developed and also new methods to find the unique optimal solutions of linear programming problems under fuzzy environment and vague environment are presented.

Cutting-edge solutions to current problems in orthopedics, supported by modeling and numerical analysis Despite the current successful methods and achievements of good joint implantations, it is essential to further optimize the shape of implants so they may better resist extreme long-term mechanical demands. This book provides the orthopedic, biomechanical, and mathematical basis for the simulation of surgical techniques in orthopedics. It focuses on the numerical modeling of total human joint replacements and simulation of their functions, along with the rigorous biomechanics of human joints and other skeletal parts. The book includes: An introduction to the anatomy and biomechanics of the human skeleton, biomaterials, and problems of alloarthroplasty The definition of selected simulated orthopedic problems Constructions of mathematical model problems of the biomechanics of the human skeleton and its parts Replacement parts of the human skeleton and corresponding mathematical model problems Detailed mathematical analyses of mathematical models based on functional analysis and finite element methods Biomechanical analyses of particular parts of the human skeleton, joints, and corresponding replacements A discussion of the problems of data processing from nuclear magnetic resonance imaging and computer tomography This timely book offers a wealth of information on the current research in this field. The theories presented are applied to specific problems of orthopedics. Numerical results are presented and discussed from both biomechanical and orthopedic points of view and treatment methods are also briefly addressed. Emphasis is placed on the variational approach to the investigated model problems while preserving the orthopedic nature of the investigated problems. The book also presents a study of algorithmic procedures based on these simulation models. This is a highly useful tool for designers, researchers, and manufacturers of joint implants who require the results of suggested experiments to improve existing shapes or to design new shapes. It also benefits graduate students in orthopedics, biomechanics, and applied mathematics.

The derivation of structural information from spectroscopic data is now an integral part of organic chemistry courses at all Universities. A critical part of any such course is a suitable set of problems to develop the student’s understanding of how structures are determined from spectra. Organic Structures from Spectra, Fifth Edition is a carefully chosen set of more than 280 structural problems employing the major modern spectroscopic techniques, a selection of 27 problems using 2D-NMR spectroscopy, more than 20 problems specifically dealing with the interpretation of spin-spin coupling in proton NMR spectra and 8 problems based on the quantitative analysis of mixtures using proton and carbon NMR spectroscopy. All of the problems are graded to develop and consolidate the student’s understanding of organic spectroscopy. The accompanying text is descriptive and only explains the underlying theory at a level which is sufficient to tackle the problems. The text includes condensed tables of characteristic spectral properties covering the frequently encountered functional groups. The examples themselves have been selected to include all important common structural features found in organic compounds and to emphasise connectivity arguments. Many of the compounds were synthesised specifically for this purpose. There are many more easy problems, to build confidence and demonstrate basic principles, than in other collections. The fifth edition of this popular textbook: • includes more than 250 new spectra and more than 25 completely new problems; • now incorporates an expanded suite of new problems dealing with the analysis of 2D NMR spectra (COSY, C H Correlation spectroscopy, HMBC, NOESY and TOCSY); • has been expanded and updated to reflect the new developments in NMR and to retire older techniques that are no longer in common use; • provides a set of problems dealing specifically with the quantitative analysis of mixtures using NMR spectroscopy; • features proton NMR spectra obtained at 200, 400 and 600 MHz and 13C NMR spectra include DEPT experiments as well as proton-coupled experiments; • contains 6 problems in the style of the experimental section of a research paper and two examples of fully worked solutions. Organic Structures from Spectra, Fifth Edition will prove invaluable for students of Chemistry, Pharmacy and Biochemistry taking a first course in Organic Chemistry. Contents Preface Introduction Ultraviolet Spectroscopy Infrared Spectroscopy Mass Spectrometry Nuclear Magnetic Resonance Spectroscopy 2DNMR Problems Index Reviews from earlier editions “Your book is becoming one of the “go to” books for teaching structure determination here in the States.

The Communist Manifesto, originally titled Manifesto of the Communist Party (German: Manifest der Kommunistischen Partei) is a short 1848 book written by the German Marxist political theorists Karl Marx and Friedrich Engels. It has since been recognized as one of the world's most influential political manuscripts. Commissioned by the Communist League, it laid out the League's purposes and program. It presents an analytical approach to the class struggle (historical and present) and the problems of capitalism, rather than a prediction of communism's potential future forms. The book contains Marx and Engels' Marxist theories about the nature of society and politics, that in their own words, «The history of all hitherto existing society is the history of class struggles.» It also briefly features their ideas for how the capitalist society of the time would eventually be replaced by socialism, and then eventually communism.

This book provides a "primer" with respect to the debate about class size between economists andeducators. In particular it offers an overview of how economists look at school funding problems, andmakes a comparison between the work of the Chicago School and others like Eric Hanushek, whichhas focused intensely on the economic relationship between public spending on educational resourcesand the cost of equipping and expanding school infrastructure, and student outcomes. The booktherefore focuses on class size as a primary example of the way in which economists have come totreat teaching and learning as a site for the development of human capital.The book also takes a historical look at the debate about class size from the perspective of theories about public choice, which haveemerged from the Chicago School through the writings of Milton Friedman. This raises the issue of how the notion of the "public" isunderstood, and whether educators and economists are coming from different perspectives about what schools should do for thecommunity. Many educationists think about the problem of class size from the perspective of a classroom teacher, who must "eyeball"her students and regard them as flesh‐and‐blood individuals, whereas economists deal in statistical numbers and shouldtherefore be understood as regarding class size as symptomatic of population issues.The book surveys the two sides of the long‐standing debate about class size and its supposed relation...

"...a fresh and an important contribution ...this book presents an ethnographically rich and conceptually strong account of recent transformations in the educational field and their implications for class relations in Turkey." · Middle East JournalMiddle classes are by definition ambiguous, raising all sorts of paradoxical questions, perceived and real, about their power and place relative to those above and below them in a class-structured society. Focusing on families of the new middle class in Istanbul, the authors of this study address questions about the social construction of middle-class reality in the context of the rapid changes that have come about through recent economic growth in global markets and the global diffusion of information technology. After 1980, Turkey saw a structural transformation from state-owned and managed industry, banking, and media and communications to privatization and open markets. The idea of being middle class and the reality of middle-class practices became open for negotiation and interpretation. This study therefore offers a particularly interesting case study of an emergent global phenomenon known as the transnational middle class, characterized by their location of work in globalizing cities, development of transnational social networks, sumptuary consumption habits, and residences in gated communities. As the authors show, this new middle class associates quality education, followed by property and lifestyle issues, with the...

Mark H.A. Davis introduced the Piecewise-Deterministic Markov Process (PDMP) class of stochastic hybrid models in an article in 1984. Today it is used to model a variety of complex systems in the fields of engineering, economics, management sciences, biology, Internet traffic, networks and many more. Yet, despite this, there is very little in the way of literature devoted to the development of numerical methods for PDMDs to solve problems of practical importance, or the computational control of PDMPs. This book therefore presents a collection of mathematical tools that have been recently developed to tackle such problems. It begins by doing so through examples in several application domains such as reliability. The second part is devoted to the study and simulation of expectations of functionals of PDMPs. Finally, the third part introduces the development of numerical techniques for optimal control problems such as stopping and impulse control problems.

Louis Theodore Open-Ended Problems. A Future Chemical Engineering Education Approach

11691.24 руб.
This is a unique book with nearly 1000 problems and 50 case studies on open-ended problems in every key topic in chemical engineering that helps to better prepare chemical engineers for the future. The term «open-ended problem» basically describes an approach to the solution of a problem and/or situation for which there is not a unique solution. The Introduction to the general subject of open-ended problems is followed by 22 chapters, each of which addresses a traditional chemical engineering or chemical engineering-related topic. Each of these chapters contain a brief overview of the subject matter of concern, e.g., thermodynamics, which is followed by sample open-ended problems that have been solved (by the authors) employing one of the many possible approaches to the solutions. This is then followed by approximately 40-45 open-ended problems with no solutions (although many of the authors’ solutions are available for those who adopt the book for classroom or training purposes). A reference section is included with the chapter’s contents. Term projects, comprised of 12 additional chapter topics, complement the presentation. This book provides academic, industrial, and research personnel with the material that covers the principles and applications of open-ended chemical engineering problems in a thorough and clear manner. Upon completion of the text, the reader should have acquired not only a working knowledge of the principles of chemical engineering, but also (and more importantly) experience in solving open-ended problems. What many educators have learned is that the applications and implications of open-ended problems are not only changing professions, but also are moving so fast that many have not yet grasped their tremendous impact. The book drives home that the open-ended approach will revolutionize the way chemical engineers will need to operate in the future.

An abstract elementary class is a class of structures of the same vocabulary (like a class of rings, or a class of fields), with a partial order that generalizes the relation "A is a substructure (or an elementary substructure) of B". The requirements are that the class is closed under isomorphism, and that isomorphic structures have isomorphic (generalized) substructures; we also require that our classes share some of the most basic properties of elementary classes, like closure under unions of increasing chains of substructures.We would like to classify this general family; in the sense of proving dichotomies: either we can understand the structure of all models in our class or there are many to some extent. More specifically we would like to generalize the theory about categoricity and superstability to this context.

This book focuses on computational methods for large-scale statistical inverse problems and provides an introduction to statistical Bayesian and frequentist methodologies. Recent research advances for approximation methods are discussed, along with Kalman filtering methods and optimization-based approaches to solving inverse problems. The aim is to cross-fertilize the perspectives of researchers in the areas of data assimilation, statistics, large-scale optimization, applied and computational mathematics, high performance computing, and cutting-edge applications. The solution to large-scale inverse problems critically depends on methods to reduce computational cost. Recent research approaches tackle this challenge in a variety of different ways. Many of the computational frameworks highlighted in this book build upon state-of-the-art methods for simulation of the forward problem, such as, fast Partial Differential Equation (PDE) solvers, reduced-order models and emulators of the forward problem, stochastic spectral approximations, and ensemble-based approximations, as well as exploiting the machinery for large-scale deterministic optimization through adjoint and other sensitivity analysis methods. Key Features: • Brings together the perspectives of researchers in areas of inverse problems and data assimilation. • Assesses the current state-of-the-art and identify needs and opportunities for future research. • Focuses on the computational methods used to analyze and simulate inverse problems. • Written by leading experts of inverse problems and uncertainty quantification. Graduate students and researchers working in statistics, mathematics and engineering will benefit from this book.

My interest to understand role of language in teaching and learning mathematical word problems evoked from my teaching and learning experiences. When I look back at my own learning experiences of mathematics at the secondary level, I remember that on a majority of occasions I felt handicapped in understanding the language of the text,especially in mathematics. This is because the language of teaching and learning mathematics is underestimated by teachers. Likewise, during my teaching I realized the need to find out about the role of language in teaching and learning word problems. As I observed students facing difficulties in understanding word problems presented in English. As a result, I wondered as to what extent language played a crucial role in understanding mathematical word problems. Was the role of language in mathematics being ignored? why did one need to understand the language of teaching and learning mathematics? These questions kept bothering me especially when I came across word problems because I believed that language and mathematical word problems were strongly related. Consequently,this book examines the connection between language and mathematical word problems.

The present book contains one hundred and sixty problems, most of them simple, in nonrelativistic quantum mechanics. Some of these problems were used previously by the authors in their courses at the Moscow Institute of Engineering and Physics. However, the majority were drawn up or selected in the course of work on the book. This book is designed for physics students who are studying quantum mechanics approximately at the level of D.I.Blokhintsev's book or Part II of "Theoretical Physics" by A.S.Kompaneyts. A number of problems is intended primarily for students who are beginning to specialize in theoretical physics and who are partially familiar with the contents of "Quantum Mechanics" by L.D.Landau and Ye.M.Lifshits. Some problems illustrate individual theoretical questions which have scarcely been considered in textbooks: sudden and adiabatic changes; Heisenberg representation of operators; probability relations in addition of momenta; isotopic spin; parity; and others. The authors have tried to use relatively elementary mathematical tools of quantum mechanics to facilitate use of the book by nontheoretical physicists. With a few exceptions, the authors have not included in this book problems which are considered in sufficient detail in the basic textbooks mentioned above and in the problem book on quantum mechanics written by V.G.Levich. Therefore, this book should be regarded chiefly as an auxiliary textbook in the study of the above books.

Bachelor Thesis from the year 2014 in the subject Business economics - Business Management, Corporate Governance, grade: 64.2, , language: English, abstract: Management of materials has over the years been a great problem to most firms in the construction industry. In construction project operations, there is always a tendency of mismanagement of materials by construction firms. As the size of the contract increases, however, so does the scale of activities concerning materials management. The aim of this research was therefore to investigate into materials management problems faced by construction firms in the Greater Accra Region. To achieve this aim, the following objectives were set out: To identify the problems in materials management practices by greater Accra firms, to identify the causes of these materials management problems, to identify proper ways of managing materials by construction firms on sites and to suggest ways of solving materials management problems by construction firms. The research instrument adopted was the use of questionnaires. Fifty-five (55) sets of questionnaires was distributed to various contractors. The sampling technique adopted was the snowball sampling technique. Quantity analysis approach was adopted for the analysis of the data which involved the use of frequency distribution tables and charts. The analysis of the data revealed that high project cost and delay were also some of the effects of improper materials management. Provisions of s...

The objective of the study was to assess the impact of river pollution on the lives of the inhabitants of the "Hechu" Peasant Association. The study revealed that the river pollution has affected the inhabitant's health seriously. Water related human health problems such as typhoid, dysentery and amoeba are commonly reported among the inhabitants. As a result, the major problems experienced by the inhabitants were increased medical expenses, low agricultural production, problems on children's education and financial loss due to labor hire. In addition, the dwellers face the death of animals due to toxic pollutants, decline in production and decrease of animal body weight. The study revealed that the respondents that were economically poor tend to be strongly affected by the river pollution when compared with the well-off and middle-class respondents. The study also revealed that the inhabitants did not take any measures to stop the river pollution. However, they took precaution measures to reduce the effect of river pollution on their health like changing the water into alcohol, and adding ash on the water and filtering the river water using cloth.

Master's Thesis from the year 2018 in the subject Mathematics - Miscellaneous, grade: 82.0%, University of Benin, language: English, abstract: P-stable hybrid linear multistep methods (HLMMs) have been an interesting focus for the numerical solution of second order initial value problems (IVPs) in ordinary di_erential equations (ODEs), because of their high order of accuracy. In this thesis, we present a new class of P-stable HLMMs with order p = 2 and p = 4 respectively for the numerical solution of second order systems. The hybrid schemes which are obtained via Pade 0 approximation approach have minimum Phase-lag error. Numerical experiments are carried out to show the accuracy of the proposed schemes. Nevertheless, the desire in this work is on high order P-stable schemes (p > 4). We give a proposition with proof, stating the limitation of the approach in search for higher order P-stable formulas. Key words: P-stability, Phase-lag error (PLE) constant, Hybrids, order, Interval of periodicity, Pade 0 approximation, Principal local truncation error (PLTE).

Xavier Lorca Tree-based Graph Partitioning Constraint

8548.5 руб.
Combinatorial problems based on graph partitioning enable us to mathematically represent and model many practical applications. Mission planning and the routing problems occurring in logistics perfectly illustrate two such examples. Nevertheless, these problems are not based on the same partitioning pattern: generally, patterns like cycles, paths, or trees are distinguished. Moreover, the practical applications are often not limited to theoretical problems like the Hamiltonian path problem, or K-node disjoint path problems. Indeed, they usually combine the graph partitioning problem with several restrictions related to the topology of nodes and arcs. The diversity of implied constraints in real-life applications is a practical limit to the resolution of such problems by approaches considering the partitioning problem independently from each additional restriction. This book focuses on constraint satisfaction problems related to tree partitioning problems enriched by several additional constraints that restrict the possible partitions topology. On the one hand, this title focuses on the structural properties of tree partitioning constraints. On the other hand, it is dedicated to the interactions between the tree partitioning problem and classical restrictions (such as precedence relations or incomparability relations between nodes) involved in practical applications. Precisely, Tree-based Graph Partitioning Constraint shows how to globally take into account several restrictions within one single tree partitioning constraint. Another interesting aspect of this book is related to the implementation of such a constraint. In the context of graph-based global constraints, the book illustrates how a fully dynamic management of data structures makes the runtime of filtering algorithms independent of the graph density.

This book is based on the application of Stochastic programming techniques in Stratified Sampling problems. Stochastic programming deals with a class of optimization models and algorithms in which some of the data may be considered as random. First chapter provides a brief historical sketch of mathematical programming, stochastic programming and its application to various fields including sampling are presented. Various methods namely E-model, modified E-model, Branch and Bound approach and chance constrained programming are used to solve Probabilistic objective function & constraint into an equivalent deterministic. Allocation problems arising in univariate sratified sampling have been considered in first four (II-V) chapters and multivariate case in the last chapter. The problems are solved by first deriving the deterministic equivalents and then by using a suitable convex programming algorithm or by using the Chance constrained technique. Allocation problem in two stage stratified sampling with random parameters in both objective and constraints is also discussed. A numerical example is presented in all chapters and the problems are solved by LINGO software.

In the present work, we present extensive new data on thallium employing multi-photon and multi-step excitation techniques in conjunction with a thermionic diode ion detector. A number of different excitation paths have been used. The first experiment addresses the observation of odd- parity levels np 2P1/2,3/2 and np 2F5/2 using two- photon excitation from the ground state. In the second set of experiments we employed a two-step excitation scheme using 6s2 7s 2S1/2 intermediate level and observed the np 2P1/2,3/2 levels upto n = 56. The even-parity levels have also been excited using three-photon excitation from the ground state revealing ns 2S1/2 and np 2P3/2,5/2 levels. In the subsequent experiments, we used a two-color three- photon excitation technique to approach the ns 2S1/2 and nd 2D3/2 levels using 7p 2P1/2 as an intermediate level. The nd series have been extended upto n = 65 and it is noticed that the intensity of the high Rydberg series scales as 1/n2.8. However, the np 2P1/2,3/2 series, which have been observed upto n = 56 scale as 1/n2.3 in contrast to the scaling law of 1/n3 for an unperturbed Rydberg series.

Kassa Tilahun Pronominal Empty Categories in Gamo

9827 руб.
This book provides a concise description of the pronominal empty categories of Gamo, an Omotic language spoken in Ethiopia. The principles of the GB Theory are relied on to identify the distribution and interpretation of pronominal empty categories in the language. Gamo is found to be a pro-drop language as subject NPs can be covert in a tensed clause. The covert NP subjects, pro, can be recovered from subject NP agreement elements attached on verbs. Its object NPs are not allowed to be covert. The absence of object NP AGR elements is the cause for this. Moreover, nominal features are absent in Gamo subordinate clauses, which in turn restrict the presence of pro in a complement clause except the relative and participial clauses. It is also discussed that pro can semantically interpreted as definitely or arbitrary based on the presence or absence of AGR elements. As the discussion of the analysis reveals Gamo pro fills in a theta or a non-theta position. PRO occurs in the subject position of infinite clauses. Its content is recovered when an antecedent NP or an implicit argument that is believed to have the status of pro is considered.

In this thesis we consider the problem of capital allocation, based on tail conditional expectation (TCE), for the class of the dependent multivariate family of distributions that essentially generalizes the classical multivariate Pareto distribution. This class can be obtained from independent exponential distributions, by a mixture of their common scale parameter. The distribution of mixture parameter belongs to the general class of distributions and, in particular, to the rich class of the exponential dispersion family (EDF). Special attention is paid to the important subclass of EDF, Tweedie family. We show that TCE-based portfolio allocation for the considered multivariate dependency structure can be represented by the tool of divided differences, actually known in numerical analysis. The results are illustrated with examples of multivariate Pareto, Weibull, and other distributions.

The derivation of structural information from spectroscopic data is now an integral part of organic chemistry courses at all Universities. A critical part of any such course is a suitable set of problems to develop the student’s understanding of how structures are determined from spectra. Organic Structures from Spectra, Fifth Edition is a carefully chosen set of more than 280 structural problems employing the major modern spectroscopic techniques, a selection of 27 problems using 2D-NMR spectroscopy, more than 20 problems specifically dealing with the interpretation of spin-spin coupling in proton NMR spectra and 8 problems based on the quantitative analysis of mixtures using proton and carbon NMR spectroscopy. All of the problems are graded to develop and consolidate the student’s understanding of organic spectroscopy. The accompanying text is descriptive and only explains the underlying theory at a level which is sufficient to tackle the problems. The text includes condensed tables of characteristic spectral properties covering the frequently encountered functional groups. The examples themselves have been selected to include all important common structural features found in organic compounds and to emphasise connectivity arguments. Many of the compounds were synthesised specifically for this purpose. There are many more easy problems, to build confidence and demonstrate basic principles, than in other collections. The fifth edition of this popular textbook: • includes more than 250 new spectra and more than 25 completely new problems; • now incorporates an expanded suite of new problems dealing with the analysis of 2D NMR spectra (COSY, C H Correlation spectroscopy, HMBC, NOESY and TOCSY); • has been expanded and updated to reflect the new developments in NMR and to retire older techniques that are no longer in common use; • provides a set of problems dealing specifically with the quantitative analysis of mixtures using NMR spectroscopy; • features proton NMR spectra obtained at 200, 400 and 600 MHz and 13C NMR spectra include DEPT experiments as well as proton-coupled experiments; • contains 6 problems in the style of the experimental section of a research paper and two examples of fully worked solutions. Organic Structures from Spectra, Fifth Edition will prove invaluable for students of Chemistry, Pharmacy and Biochemistry taking a first course in Organic Chemistry. Contents Preface Introduction Ultraviolet Spectroscopy Infrared Spectroscopy Mass Spectrometry Nuclear Magnetic Resonance Spectroscopy 2DNMR Problems Index Reviews from earlier editions “Your book is becoming one of the “go to” books for teaching structure determination here in the States. Great work!” “…I would definitely state that this book is the most useful aid to basic organic spectroscopy teaching in existence and I would strongly recommend every instructor in this area to use it either as a source of examples or as a class textbook”. Magnetic Resonance in Chemistry “Over the past year I have trained many students using problems in your book – they initially find it as a task. But after doing 3-4 problems with all their brains activities… working out the rest of the problems become a mania. They get addicted to the problem solving and every time they solve a problem by themselves, their confident level also increases.” “I am teaching the fundamentals of Molecular Spectroscopy and your books represent excellent sources of spectroscopi
