Taschenbuch. Condition: Neu. Neuware -This volume gathers the invited talks of the XIII International Work shop on Condensed Matter Theories which took place in Campos do Jordao near Sao Paulo, Brazil, August 6-12, 1989. It contains contributions in a wide variety of fields including neutral quantum and classical fluids, electronic systems, composite materials, plasmas, atoms, molecules and nuclei, and as this year's workshop reflected the natural preoccupation in materials science with its spectacular prospect for mankind, room tempera ture super-conductivity. All topics are treated from a common viewpoint: that of many-body physics, whether theoretical or simu1ational. Since the very first workshop, held at the prestigious Instituto de Fisica Teorica in Sao Paulo, and organized by the same organizer of the 1989 workshop, Professor Valdir Casaca Aguilera-Navarro, the meeting has taken place annually six times in Latin America, four in Europe and three in the United States. Its principal objective has been to innitiate and nurture collaborative research networks of scientists interested in the IDultidisciplinary aspects of many-body theory applied to problems in con densed-matter physics. Financial as well as moral support is gratefully appreciated by all: of the CLAF in Rio, the CNPq in Brasilia, the FAPESP and the FUNDUNESP in Sao Paulo, and the U.S. Army Research Office in Durham, NC, USA.

Taschenbuch. Condition: Neu. Neuware -Where were the amino acids, the molecules of life, created: perhaps in a lightning storm in the early Earth, or perhaps elsewhere in the cosmos This book argues that at least some of them must have been produced in the cosmos, and that the fact that the Earthly amino acids have a specific handedness provides an important clue for that explanation. The book discusses several models that purport to explain the handedness, ultimately proposing a new explanation that involves cosmic processing of the amino acids produced in space. The book provides a tour for laypersons that includes a definition of life, the Big Bang, stellar nucleosynthesis, the electromagnetic spectrum, molecules, and supernovae and the particles they produce.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Buch. Condition: Neu. Neuware -Before the arrival of penicillin in the 1940s, phage therapy was one of the few weapons doctors had against bacterial infections. It saved the life of Hollywood legend Tom Mix before being abandoned by Western science. Now, researchers and physicians are rediscovering the treatment, which pits phage viruses against their natural bacterial hosts, as a potential weapon against antibiotic-resistant infections.The Forgotten Cure traces the story of phages from Paris, where they were discovered in 1917; to Tbilisi, Georgia, where one of phage therapy¿s earliest proponents died at the hands of Stalin; to the Nobel podium, where prominent scientists have been recognized for breakthroughs stemming from phage research. Today, a crop of biotech startups and dedicated physicians is racing to win regulatory approval for phage therapy before superbugs exhaust the last drug in the medical arsenal. Will they clear the hurdles in time Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 148 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Topology is a relatively young and very important branch of mathematics. It studies properties of objects that are preserved by deformations, twistings, and stretchings, but not tearing. This book deals with the topology of curves and surfaces as well as with the fundamental concepts of homotopy and homology, and does this in a lively and well-motivated way. There is hardly an area of mathematics that does not make use of topological results and concepts. The importance of topological methods for different areas of physics is also beyond doubt. They are used in field theory and general relativity, in the physics of low temperatures, and in modern quantum theory. The book is well suited not only as preparation for students who plan to take a course in algebraic topology but also for advanced undergraduates or beginning graduates interested in finding out what topology is all about. The book has more than 200 problems, many examples, and over 200 illustrations.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 156 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -In most developed countries, the epidemiological disease profile has changed from infectious to degenerative, causing major alterations in epidemiological thinking and public health policies. Less developed nations have to deal with a more complex situation, because social disparities create highly unequal health conditions, the affluent being afflicted by degenerative conditions, whereas the poorer social segments continue to suffer infectious diseases, but also begin to feel the effects of chronic illness. At the turn of the 21st century, equity in health care is not being served, and social justice has lost credibility as a conceptual driving force of public health policies. Rampant injustice confirms that theories, reality and suggested practices of just social orders are flawed, leaving the needy without help or hope in a world of flagrant ethical inadequacy. And yet, mainstream bioethics loses meaning and relevance as it clings to the principle of justice and hails such concepts as global justice and universal health-care equity, misleadingly focusing on justice as a desideratum. This book pleads for an urgent turn towards directly addressing injustice as a reality that requires pressingly needed arguments and proposals to inspire realistic public health policies and programs based on an ethics of protection. Ever since Hobbes, all shades of political philosophy accept that the basic obligation of the ruling power is to protect its subjects. The ethics of protection emphasizes aiding the needy and the disempowered in obtaining access to basic goods and services related to health-care. Public health is called upon to fulfill protective obligations to guarantee disease prevention and medical services to the population, taking special care to safeguard those unable to cover their health-care needs in market-oriented medical services and institutions. The bioethics of protection developed in this text presents specific and explicit guide-lines to assure that protective public health actions be efficacious (problem-solving), efficient (sustainable cost/benefit relation) and ethically sound (respecting human rights and the common weal). These guide-lines are designed to give ethical support and justification to public health policies even when they require some unavoidable limitations of individual autonomy to promote social health benefits.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 116 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Creating New Medical Ontologies for Image Annotation focuses on the problem of the medical images automatic annotation process, which is solved in an original manner by the authors. All the steps of this process are described in detail with algorithms, experiments and results. The original algorithms proposed by authors are compared with other efficient similar algorithms.In addition, the authors treat the problem of creating ontologies in an automatic way, starting from Medical Subject Headings (MESH). They have presented some efficient and relevant annotation models and also the basics of the annotation model used by the proposed system: Cross Media Relevance Models. Based on a text query the system will retrieve the images that contain objects described by the keywords.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 120 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Developed and developing economies alike face increased resource scarcity and competitive rivalry. In this context, science and technology appear as an essential source of competitive and sustainable advantage at national and regional levels. However, the key determinant of their efficacy is the quality and quantity of entrepreneurship-enabled innovation that unlocks and captures the benefits of the science enterprise in the form of private, public or hybrid goods. Linking basic and applied research with the market, via technology transfer and commercialization mechanisms, including government-university-industry partnerships and capital investments, constitutes the essential trigger mechanism and driving force of sustainable competitive advantage and prosperity. In this volume, the authors define the terms and principles of knowledge creation, diffusion, and use, and establish a theoretical framework for their study. In particular, they focus on the ¿Quadruple Helix¿ model, through which government, academia, industry, and civil society are seen as key actors promoting a democratic approach to innovation through which strategy development and decision making are exposed to feedback from key stakeholders, resulting in socially accountable policies and practices.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 72 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -This book contains an introduction to three topics in stochastic control: discrete time stochastic control, i. e. , stochastic dynamic programming (Chapter 1), piecewise - terministic control problems (Chapter 3), and control of Ito diffusions (Chapter 4). The chapters include treatments of optimal stopping problems. An Appendix - calls material from elementary probability theory and gives heuristic explanations of certain more advanced tools in probability theory. The book will hopefully be of interest to students in several elds: economics, engineering, operations research, nance, business, mathematics. In economics and business administration, graduate students should readily be able to read it, and the mathematical level can be suitable for advanced undergraduates in mathem- ics and science. The prerequisites for reading the book are only a calculus course and a course in elementary probability. (Certain technical comments may demand a slightly better background. ) As this book perhaps (and hopefully) will be read by readers with widely diff- ing backgrounds, some general advice may be useful: Don¿t be put off if paragraphs, comments, or remarks contain material of a seemingly more technical nature that you don¿t understand. Just skip such material and continue reading, it will surely not be needed in order to understand the main ideas and results. The presentation avoids the use of measure theory.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 304 pp. Englisch.

A final chapter presents a self-contained account of notions and results in algebra that are used. Researchers in mathematics and mathematical physics will also find this book useful.A separate solutions manual is available for instructors.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 388 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Challenges of Astronomy in a unique collection of thirty astronomy experiments ranging from ancient astronomy to cosmology. Each of the experiments contains one or more challenges for the reader. The progression is from the Earth outward through the solar system to the stellar and galactic realm. Topics include the shape of the sky, Stonehenge as a stoneage abacus, determination of the size of the Earth, the distance of the Moon and planets, Kepler's laws, planetary mass and density, the temperatures and atmospheres of planets, the speed of light, the distances of stars, the nature of the quiet and active Sun, photometry and spectroscopy, stars clusters and variable stars, fundamental properties of stars, and Olber's paradox.Challenges of Astronomy is a translation and extensive revision of a German-language resource book for secondary school teachers of science. Physical science teachers will find this edition too a rich resource of experiments to their own milieus, but it is suitable for many other English-language readers too, from northern and southern hemisphere locations. The beginning experiments are suitable for bright high school and non-science major university students while the later experiments which offer increasingly difficult challenges are more suitable for sciences majors. Amateurs with a variety of skills will find this hands-on book entertaining, informative, and useful.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 248 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Intended for advanced students of physics, chemistry, and related disciplines, this text treats the quantum theory of atoms and ions within the framework of self-consistent fields. It treats the structure and spectra of atoms and ions, their behavior in external fields, and their interactions, including collisions. Data needed for the analysis of collisions and other atomic processes are also included, making the book useful as a reference for researchers as well as students. In the main text, simple and convincing methods are used to explain the fundamental properties of atoms, molecules, and clusters; details and more advanced aspects of these topics are treated in the problems at the end of each chapter. The first part of the book is devoted to properties of atoms and ions considered as quantum systems of electrons orbiting a heavy Coulomb center. Self-consistent fields and the shell model give a logical and consistent picture, and provide reliable models for the analysis of atomic properties. The second part deals with interactions and collisions of particles -- including bound systems, such as molecules, clusters, and solids. The aim here is to relate the internal structure of the atoms to the interactions between them, providing useful insights for applications; the accompanying data in tables, charts, and spectra complement the theoretical discussion.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 460 pp. Englisch.

Buch. Condition: Neu. Neuware -With this collections volume, some of the important works of Willem van Zwet are moved to the front layers of modern statistics. The selection was based on discussions with Willem, and aims at a representative sample. The result is a collection of papers that the new generations of statisticians should not be denied. They are here to stay, to enjoy and to form the basis for further research.The papers are grouped into six themes: fundamental statistics, asymptotic theory, second-order approximations, resampling, applications, and probability. This volume serves as basic reference for fundamental statistical theory, and at the same time reveals some of its history.The papers are grouped into six themes: fundamental statistics, asymptotic theory, second-order approximations, resampling, applications, and probability.

Taschenbuch. Condition: Neu. Neuware -Descriptive set theory has been one of the main areas of research in set theory for almost a century. This text attempts to present a largely balanced approach, which combines many elements of the different traditions of the subject. It includes a wide variety of examples, exercises (over 400), and applications, in order to illustrate the general concepts and results of the theory.This text provides a first basic course in classical descriptive set theory and covers material with which mathematicians interested in the subject for its own sake or those that wish to use it in their field should be familiar. Over the years, researchers in diverse areas of mathematics, such as logic and set theory, analysis, topology, probability theory, etc., have brought to the subject of descriptive set theory their own intuitions, concepts, terminology and notation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -¿In statistics, analysis of variance (ANOVA) is a collection of statistical models used to distinguish between an observed variance in a particular variable and its component parts. In its simplest form, ANOVA provides a statistical test of whether or not the means of several groups are all equal, and therefore generalizes a test between these groups. One test often used by statisticians and researchers in their work is the Two-Way ANOVA, which determines the differences--and possible interactions--when variables are presented from the perspective of two or more categories. When a Two-Way ANOVA is implemented, it enables one to compare and contrast variables resulting from independent or joint actions. This brief provides guidance on how R can be used to facilitate Two-Way ANOVA for data analysis and graphical presentation. Along with instruction on the use of R and R syntax associated with Two-Way ANOVA, this brief will also reinforce the use of descriptive statistics and graphicalfigures to complement outcomes from parametric Two-Way ANOVA.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 148 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -The following lecture notes correspond to a course taught for several years, first at the University of Paris-Nord (France) and then at the University of Bologna (Italy). They are mainly addressed to nonspecialists in the subject, and their purpose is to present in a pedagogical way most of the techniques used in the microlocal treatment of semiclassical problems coming from quantum physics. Both the standard Coo pseudodifferential calculus and the analytic microlocal analysis are developed, in a context that remains intentionally global so that only the relevant difficulties of the theory are encountered. The main original ity lies in the fact that we derive all the main features of analytic microlocal analysis from a single a priori estimate, which turns out to be elementary once the Coo pseudodifferential calculus is established. Various detailed exercises are given at the end of the main chapters, most of them being easily solvable by students. Besides illustrating the main results of the lecture, their aim is also to introduce the reader to various further developments of the theory, such as the functional calculus of pseudodifferential operators, properties of the analytic wave front set, Gevrey classes, the use of coherent states, the notion of semiclassical measures, WKB constructions. Applications to the study of the Schrodinger operator are also discussed in the text, so that they may help the understanding of new notions or general results where they appear by replacing them in the context of quantum mechanics.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 204 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Created to teach students many of the most important techniques used for constructing combinatorial designs, this is an ideal textbook for advanced undergraduate and graduate courses in combinatorial design theory. The text features clear explanations of basic designs, such as Steiner and Kirkman triple systems, mutual orthogonal Latin squares, finite projective and affine planes, and Steiner quadruple systems. In these settings, the student will master various construction techniques, both classic and modern, and will be well-prepared to construct a vast array of combinatorial designs. Design theory offers a progressive approach to the subject, with carefully ordered results. It begins with simple constructions that gradually increase in complexity. Each design has a construction that contains new ideas or that reinforces and builds upon similar ideas previously introduced. A new text/reference covering all apsects of modern combinatorial design theory. Graduates and professionals incomputer science, applied mathematics, combinatorics, and applied statistics will find the book an essential resource.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 320 pp. Englisch.

Buch. Condition: Neu. Neuware -This book gives an elementary treatment of the basic material about graph spectra, both for ordinary, and Laplace and Seidel spectra. The text progresses systematically, by covering standard topics before presenting some new material on trees, strongly regular graphs, two-graphs, association schemes, p-ranks of configurations and similar topics. Exercises at the end of each chapter provide practice and vary from easy yet interesting applications of the treated theory, to little excursions into related topics. Tables, references at the end of the book, an author and subject index enrich the text.Spectra of Graphs is written for researchers, teachers and graduate students interested in graph spectra. The reader is assumed to be familiar with basic linear algebra and eigenvalues, although some more advanced topics in linear algebra, like the Perron-Frobenius theorem and eigenvalue interlacing are included.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 264 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -ince 1985, it has been my privilege to be the Director of The - ciety of Byron Smith Fellows. During the years in which Byron SSmith was with us, his former fellows would meet at the Ame- can Academy of Ophthalmology¿s annual meeting. They would present to him, and to one another, interesting cases of their own compli- tions that had occurred or cases that had been sent to them that were complications to be repaired. This forum provided the fellows with an excellent format for evaluating their own problems and also for d- cussing how to treat extremely difficult cases. Shortly after Dr. Brian Brazzo completed his fellowship with me in 1998, he asked if I thought it would be appropriate for him to edit a new book on complications of ophthalmic plastic surgery. Certainly, during his fellowship, it became apparent that Dr. Brazzo was pr- ably the most gifted academician and writer that I had ever had the pleasure of training and meeting. I could think of no one more - propriate to continue the work initiated by Dr. Byron Smith and c- ried on by his students.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 284 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware - In recent years, the techniques of electron microscopy have developed so widely and rapidly that they now cover the fields of research once the unique ll:panage of sister research techniques such as biochemistry, physiology, immunology, X-ray diffraction, etc. It is now possible to reach molecular and submolecular levels, making this technique indispensable in every type of research. Electron microscopy alone often provides enough information to solve given problems. In the field of the connective tissue matrix, knowledge of the molecular structure of collagen, pro teoglycans and elastin and their interaction has been to a large extent elucidated by electron microscopy. The field over which electron microscopy ranges in the investigation of the connective tissue matrix is so wide that the aim of this volume is to collect the main ultrastructural acquisitions disseminated in various journals and monographs in one book. The intent ofthis volume is to: (a) integrate different and new microscopic methods and review the results of such an integrative approach; (b) present a comprehensive ultrastructural account of selected aspects of the field; (c) point out gaps or controversial topics in our knowledge; (d) outline pertinent future research and expansion of the subject.

Taschenbuch. Condition: Neu. Neuware - We are again proud to present an excellent volume of contemporary topics in NMR and EPR to the biological community. The philosophy behind the volume and the presentation of each chapter remains at the high level reflected in our earlier volumes: to be current, pedagogical, and critical. The first chapters, as always, address a subject related to in-vivo biology. Gabby Elgavish addresses NMR spectroscopy of the intact heart. lain Campbell and colleagues present a state-of-the-art description of NMR methods for probing enzyme kinetics in intact cells and tissues. Klaus Mobius and Wolfgang Lubitz have produced a thorough review of the principles and applications of ENDOR spectroscopy in photobiology and biochemistry including discussions of liquid and solid state ENDOR as well as CIDEP-enhanced ENDOR. The final chapter by Hans Vogel and Sture Forsen addresses a contemporary problem in inorganic biochemistry, namely cation binding to calcium binding proteins. We are pleased to announce that a special forthcoming volume will be devoted entirely to the subject of 'Spin Labeling: Theory and Applications (3rd compendium).' A substantial degree of progress has occurred in this important area of ESR in biology since the last treatise on the subject in 1979. Lastly, we acknowledge our colleagues in the field who continue to support this excellent series both as subscribers and contributors. We pledge to continue servicing the community as long as the need exists.

Taschenbuch. Condition: Neu. Neuware -Pell's equation is part of a central area of algebraic number theory that treats quadratic forms and the structure of the rings of integers in algebraic number fields. It is an ideal topic to lead college students, as well as some talented and motivated high school students, to a better appreciation of the power of mathematical technique. Even at the specific level of quadratic diophantine equations, there are unsolved problems, and the higher degree analogues of Pell's equation, particularly beyond the third, do not appear to have been well studied. In this focused exercise book, the topic is motivated and developed through sections of exercises which will allow the readers to recreate known theory and provide a focus for their algebraic practice. There are several explorations that encourage the reader to embark on their own research. A high school background in mathematics is all that is needed to get into this book, and teachers and others interested in mathematics who do not have (or have forgotten) a background in advanced mathematics may find that it is a suitable vehicle for keeping up an independent interest in the subject.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware - There is much evidence to suggest that prostaglandins may have a physiological role to play in the control of thyroid gland metabolism, although the precise nature of this role remains to be defined. Prostaglandins have been found in normal thyroid tissue, and there is evidence of increased levels in some, but not all, cases of medullary carcinoma of the thyroid. which may account for the associated diarrhea. Exogenous prostaglandins, like TSH, bind to thyroid plasma mem branes, stimulate the adenylate cyclase-cyclic AMP system, thyroid hormone secretion, iodide organification, colloid droplet formation, glucose oxidation, and 32p incorporation into phospholipids. Prosta glandins of the E series are the most potent, although their maximal effects are generally less than the maximal effects of TSH. The interrelationships existing between TSH and prostaglandins have been the subject of intensive investigation, but as yet no one uni fying concept has emerged. TSH and prostaglandins have been shown to occupy different receptors on the thyroid plasma membrane. Al though TSH can increase intracellular prostaglandin levels, probably as a result of increased synthesis, prostaglandins do not appear to be essential intermediates in TSH action on adenylate cyclase. The pos sibility that prostaglandins are part of a negative feedback system con trolling TSH action is, as yet, a tentative hypothesis, and further work will be required to unravel the interrelationships between these sub stances that now appear to be far more complex than has been envisaged thus far.

Taschenbuch. Condition: Neu. Neuware - The use of ultrasound for various diagnostic techniques in medicine continues to increase in popularity and complexity. It seems possible that the prediction of the National Science Foun dation that ultrasonic techniques may be used as frequently as X-ray techniques by the end of the decade may indeed be fulfilled. The annual scientific meeting of the American Institute of Ultra sound in Medicine is the only meeting held regularly on the North American continent and devoted solely to the diagnostic use of ultrasound. Under these circumstances it is not surprising to find that both the attendance at these meetings and the number of papers submitted for presentation, are increasing markedly each year. The papers presented at these meetings probably reflect the 'state-of-the-Art' reasonably accurately. The Proceedings of these annual meetings are therefore a valuable record of the current state of ultrasonic diagnostic techniques in the U.S.A. Even though it is not possible to print in extenso every paper presented at the meeting, an attempt has been made with this volume, by increasing the length of the papers printed in abstract form, to enable the reader to obtain an overall view of current developments and research on this continent in all fields of ultrasonic medical diagnostic technology. Speed of publication is essential if this volume is to contain current information.

Taschenbuch. Condition: Neu. Neuware -During the last 20 years interest in high-resolution x-ray diffractometry and reflectivity has grown as a result of the development of the semiconductor industry and the increasing interest in material research of thin layers of magnetic, organic, and other materials. For example, optoelectronics requires a subsequent epitaxy of thin layers of different semiconductor materials. Here, the individuallayer thicknesses are scaled down to a few atomic layers in order to exploit quantum effects. For reasons of electronic and optical confinement, these thin layers are embedded within much thicker cladding layers or stacks of multilayers of slightly different chemical composition. It is evident that the interface quality of those quantum weHs is quite important for the function of devices. Thin metallic layers often show magnetic properties which do not ap pear for thick layers or in bulk material. The investigation of the mutual interaction of magnetic and non-magnetic layers leads to the discovery of colossal magnetoresistance, for example. This property is strongly related to the thickness and interface roughness of covered layers.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 428 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware - This book develops the use of statistical data analysis in finance, and it uses the statistical software environment of S-PLUS as a vehicle for presenting practical implementations from financial engineering. It is divided into three parts. Part I, Exploratory Data Analysis, reviews the most commonly used methods of statistical data exploration. Its originality lies in the introduction of tools for the estimation and simulation of heavy tail distributions and copulas, the computation of measures of risk, and the principal component analysis of yield curves. Part II, Regression, introduces modern regression concepts with anemphasis on robustness and non-parametric techniques. The applications include the term structure of interest rates, theconstruction of commodity forward curves, and nonparametric alternativesto the Black Scholes option pricing paradigm. Part III, Time Series and State Space Models, is concerned with theories of time series and of state space models. Linear ARIMA models are applied to the analysis of weather derivatives, Kalman filtering is applied to public company earnings prediction, andnonlinear GARCH models and nonlinear filtering are applied to stochasticvolatility models. The book is aimed at undergraduate students in financial engineering,master students in finance and MBA's, and to practitioners with financial data analysis concerns.
