description: The book is a thorough introduction to ancient Egyptian language and writing. It aims to fill a significant gap in Greek literature, as there is no other relevant study available. It is based on many years of research and teaching experience at the Department of Mediterranean Studies of the University of the Aegean. It is aimed at undergraduate and postgraduate students of archaeology, linguistics, and philology, as well as teachers or professional archaeologists and linguists who wish to gain an in-depth understanding of one of the most important ancient languages of the southeastern Mediterranean. Through original hieroglyphic inscriptions, topics related to the following are presented and analyzed: - the historical and linguistic evolution of the Egyptian writing system from the proto-hieroglyphs of the Predynastic period to the hieroglyphs of the Pharaonic period and the Coptic alphabet, - the history of decipherment, - the relationship between Egyptian and other linguistic subgroups of the Afro-Asiatic family, - the morphology and use of hieroglyphic signs (ideograms, phonograms, taxograms), - types of writing (hieroglyphic, hieratic, Coptic), - the basic principles and distinctive features of the language, - the components of royal and divine nomenclature, - formulas for votive offerings and funerary offerings. Thematic lists of hieroglyphic signs with their transcription and meaning are also included, as well as a method for designing and recording them. Original interactive exercises and educational quizzes complete the theme of each unit.

description: The book is intended for undergraduate students at Greek universities who are taking a basic algebra course. The book accompanies a standard undergraduate-level basic algebra textbook and aims to help readers through the analytical solution of exercises of varying levels of difficulty, subject matter, and content, to understand the fundamental principles, techniques, and methods of basic algebra. The book is mainly intended for students of mathematics (but also related departments) at Greek universities. The book requires only basic knowledge from other courses, which is summarized, so it can also be used as an aid to understanding the fundamental principles, techniques, and methods of basic algebra by non-specialized readers. It can therefore be used by teachers, students, professionals in the field (professors), and anyone interested in understanding the basic principles of group and ring theory. The main part of the book is devoted to the analytical solution of exercises concerning two of the most fundamental structures of modern algebra, the group structure and the ring structure, as well as their applications. The book is divided into two parts (group theory and ring theory) and 14 chapters. Each chapter of the book develops, without proof, a concise theory that is used to solve the exercises. This is followed by detailed solutions to exercises at various levels (comprehension exercises, computational exercises, theoretical exercises, exercises that extend known results, etc.) related to the concise theory presented. Some of the exercises are accompanied by comments highlighting their relationship to other exercises, to corresponding theoretical topics or extensions thereof, or with references to the literature. Finally, at the end of each chapter, a series of exercises is proposed for solution.

description: The book deals with various aspects of the issue of the Information Society and the Knowledge Economy, and largely combines theory with empirical data and examples from Greece, Europe and elsewhere. It begins by placing Information and Communication Technologies (ICTs) in a historical context, analyzing the reasons why they are a General Purpose Technology and have led to the emergence of the most recent major techno-economic paradigm and the triggering of an ongoing socio-economic transformation. Chapter 2 seeks to contribute to a deeper understanding of the processes, the forces driving them, the obstacles and the structural problems associated with the effort to develop the Information Society in Greece. Chapter 3 describes the evolutionary path of mass computing information and communication technologies, as well as current technological trends and forecasts (Cloud Computing, Internet of Things, etc.). Chapter 4 deals with the topic of open technologies in the ICT field, namely Free Software/Open Source Software (FOSS), Open Standards and Open Hardware. Chapter 5 analyzes the concept of eGovernment, describing how it is defined and its main benefits, the methodology for measuring its level of development and the basic conditions for its realisation. Chapter 6 deals with the concept of the ICT Ecosystem and emphasizes the Greek case, analyzing the characteristics of companies operating in the field, in comparison with the international environment, in order to highlight the Greek specificities. Chapter 7 is devoted to the analysis of the degree of utilization of ICT by the domestic production system, and includes several empirical data and examples. Chapters 8 and 9 deal with the issue of telecommunications and broadband, and in particular describe the role of the public sector in the development of new generation broadband networks (fibre optics) and the main methods available for calculating the cost of telecommunications/broadband services respectively. Chapter 10 analyzes the changes that ICT, and in particular the Internet, have already brought and are expected to bring about at individual and societal level, such as the possibilities they offer in the fields of work, education and health (teleworking, eLearning, eHealth). The final chapter of the book is specifically referred  to the role of information technology and the Internet in education and research, and attempts to review IT applications in the field of engineering and research.

description: In the proposed book we present the fundamental data structures, which are widely used in a variety of applications. Emphasis is placed both on the theoretical development of basic techniques for designing and analyzing data structures and on the implementation of efficient programs. The purpose of the book is to provide readers with an understanding of the operation of important data structures and their applications, and to familiarize them with basic techniques for designing and analyzing data structures and algorithms. In addition, the book provides implementations in the Java programming language. Java was chosen for two reasons. First, a significant amount of software produced for modern systems is developed in Java. Second, we take advantage of the use of object-oriented design to represent data structures through abstract data types. The material in the book is divided into three parts. In the first part (Chapters 1-4), basic concepts and techniques for designing and analyzing data structures and algorithms are introduced. Elementary data structures are also introduced, which form the basis of the more advanced methods discussed in the next two parts. In the second and main part of the book (Chapters 5-12), we analyze the most important data structures used today (stacks and queues, priority queues, search trees, hash tables, etc.). In the third part (Chapters 13-15), we discuss more advanced issues of designing and analyzing efficient data structures. The book is mainly addressed to computer science students in the first two years of the first cycle of studies (undergraduate students), who have acquired basic knowledge on computer programming and computer operation, but also to interested professionals. In addition, the third part of the book can be covered in courses of older semesters or even in the context of a corresponding postgraduate course.

description: The textbook presents, analyses, interprets and maps the basic theoretical tools for understanding and managing risks, crises and disasters (natural, environmental, na-tech), to which a number of related disciplines (geography, sociology, psychology, engineering and political sciences) have contributed. In particular, the text focuses on the management concepts/tools attributed to the terms 'Risk', 'Exposure', 'Vulnerability', 'Adaptivity', 'Risk Recruitment'. Each management concept/tool is accompanied by a chapter highlighting mutually reinforcing theoretical issues and empirical examples, which conclude with the corresponding tools and methods of regulation offered to mitigate crises and disasters, reduce losses or recover already affected communities and areas. In a separate chapter, the dynamics in space-time and the interactions of the above-mentioned conditions/instruments are examined. The aim of the textbook, through the consolidation of these tools, is to enhance the ability of readers/students to identify the trigger from the causes of disasters and to distinguish the immediate from the root causes of hazards and catastrophic losses. In addition, the aim is to develop readers' ability to formulate alternative 'management pathways' for risk, crisis and disaster management for evaluation and implementation in the context of a modern approach to Risk Governance.

description: By microsurgery we mean surgery with enlargement of the surgical field. Although enlargement of the surgical field is necessary in many surgical specialties (plastic surgery, ophthalmology, otolaryngology, orthopaedics, neurosurgery), the term microsurgery refers mainly to surgery of small vessels and nerves and refers to reconstructive surgery. The purpose of this textbook is to transfer from theory to practice of microsurgical suturing techniques. The topics covered in the book initially include some introductory elements, the early historical applications of microsurgery, as well as the use of magnifiers and the microscope, special instruments and sutures. A detailed description is given of the training methods for learning microsurgical techniques, which are performed first on synthetic materials, then on non-living biological tissues and finally on living experimental animals (guinea pigs). Microsurgical sutures are described in detail, including arterial end-to-end anastomosis, venous end-to-end anastomosis, end-to-side suturing, use of venous graft, free flap transfer, end-to-end nerve suturing and nerve suturing with venous graft and nerve conduits. A detailed description of all suturing methods shall be given and a schematic or video demonstration of each of them shall be provided. To complete the training, the preparation of the experimental animals and a description of the anaesthesia administered shall be given. Finally, the clinical applications of microsurgery are described, mainly concerning the coverage of large tissue defects using free flaps, cases of reattachment of amputated limbs, breast reconstruction after mastectomy, treatment of lymphedema and tissue allotransplantation (facial, hand, etc.).

description: The content of this book is indicated by its title. It is an introduction to Archivonomy, the science of records management. It is addressed, primarily, to students studying in the broader field of information sciences and reflects our many years of related educational and professional activity in the Department of Library and Information Systems of TEI of Athens and the General Archives of the State. The book aims to clarify basic issues, attempting to answer questions such as: what is an archive; how and why is it created; why do we keep the archives; what is their role in everyday social activity, on an individual and collective level? What is their importance for the study of the past? Similarly, it attempts to highlight the existence and importance of Archives as distinct cultural institutions similar to Libraries and Museums. Finally, the basic methodological principles of archaeology are examined, as well as the significant changes brought about in archives and their management by modern digital technology. Theoretically, the book is concerned with analogue historical archives. De facto, however, it also examines active (administrative) archives, as modern scientific views support the unitary character of archival material. Of course, the new digital reality in the field of archives, whether it concerns the management of digitised documents or access to the rich content of the Internet, could not be ignored. The management and preservation of primary digital documents (concepts that are almost identical in the modern digital reality) is another issue that is tentatively addressed in the book.

description: Bilingualism in Greece, as in the rest of the world, can be explained historically: many languages and linguistic varieties coexist in Greece because this area was part of large multilingual and multicultural state formations, such as the Ottoman Empire. In more recent history, migration and the movement of people to and from Greece have created additional types of bilingualism, with Greek coexisting with other languages. This creates the need to teach Greek as a second language from a bilingual perspective. Many applications have been designed and implemented as part of large-scale educational intervention programs targeting specific groups of students (Muslim students in Thrace, Roma, foreign and repatriated students, students of Greek origin in the diaspora). funded by European and national resources and implemented by Greek universities. The common element of these programs, although they focus on different population groups, is the teaching/learning of Greek as a second language. In each case, we have a distinct type of bilingualism with different languages being combined with Greek. In this context, valuable experience has been gained in teaching Greek as a second language. This experience is constantly enriched by applications in an electronic environment. The conclusions from teaching Greek as a second language in a conventional and electronic environment and from the perspective of bilingualism are of broader significance because they contribute to a redefinition of both mother tongue and foreign language teaching.

It does not follow the usual book syllabus covering the basic functions of commercial GIS software, but provides a theoretical and practical foundation for a geospatial representation approach. It introduces the basic principles of perception, conceptualization and representation of geospatial phenomena, basic spatial properties/relationships, their description in an information environment, the main domain/entity models, basic data structures, data collection and processing sources and technologies, their organization in databases, and the possibilities of spatial analysis and geo-visualization. In order to highlight the different requirements of fields using geospatially referenced information, the book concludes with a presentation of representative such applications. At the end of each chapter, the relevant literature and key terms are mentioned. The book is intended for university undergraduate level readers. Geographic Information Science, with its technological dimension (Geoinformatics and GIS), can be approached from 3 perspectives: (a) the needs of the user/application (user perspective), (b) the understanding of the specificity of geographic information and the methodological design of system and applications (modelling perspective), and (c) the implementation of systems-applications at the physical level (computing perspective). Since applications and computing technology capabilities are constantly changing, a clear priority is given by intention to the less volatile methodological approach. This ensures the timeless character of the book and the value of the knowledge provided to the reader.

This is a textbook which is related to a subject of particular importance as seismic engineering is one of the core subjects of the Greek Polytechnics due to the significant seismicity that characterizes our country. This book seeks in an interactive way to familiarize the students and every reader with the concepts of seismic design of concrete structures with emphasis on high-rise buildings which constitute the majority of the structural fabric. An important element concerning the subject matter of the textbook is the very detailed numerical examples of application that it includes as well as the extensive commentary on each step of the analysis and dimensioning of structures. It is considered that no similar textbook is currently available in both conventional and electronic-interactive formats.

description:
The main objective of this book is the presentation of  methods of finite differences for the solution of parabolic, elliptic and hyperbolic partial differential equations. The application of these methods to the solution of various practical problems is emphasized, avoiding scholastic mathematical derivations. For this reason for several fundamental methods, computer  programs are presented in FORTRAN 90/95, which may be easily translated into a different computer language.

The material of the book was developed while teaching a relative course since 1980 in the  post graduate program of Agricultural Engineering and Water Resources in the Department of Hydraulics, Soil Science and Agricultural Engineering of the Aristotle University of Thessaloniki.

For the completeness of the material of the book the first chapter is devoted to the short description of some methods of basic numerical analysis, which are necessary for the comprehension of the main material of the book. The reader of this book can find detailed description of these methods in the book of the same author titled “Numerical Analysis”.

description: The book is a handbook on the subject of monument protection, restoration, and management. It recounts how various societies dealt with the remnants of the past from classical times to the end of the 18th century, when the modern concept of monument protection emerged, namely the realization of the need to preserve them as carriers of memory and spiritual values essential to the mental balance of present and future generations. It also recounts the spread of this new concept in Europe and its various practical applications, which gave rise to the various theoretical approaches that subsequently emerged: the classicist concept of monument protection, the 'school' of total stylistic restoration, the Movement against the Restoration of Monuments, the approaches of 'philological restoration' and 'historical restoration', the approach to the issue by A. Riegl and G. Giovannoni, and the 1931 Athens Charter. The following chapters trace the evolution of ideas after World War II, on the one hand up to the 1964 Venice Charter, the main international regulatory text on intervention in monuments still in force today, and on the other hand during the last quarter of the 20th century and the early 21st century, when new perceptions emerged as a result of the globalisation of the issue. At the same time, the history of monument protection in Greece is presented, with its three main periods (1. From the founding of the modern Greek state to World War II, 2. From the end of World War II to the dictatorship of 1967, and 3. From 1974 to the present), the main interventions, the key players, and the legislative and administrative framework. The book concludes with special chapters on the restoration of the Acropolis after 1975 and on the terminology of monumental restoration (in English, French, and Italian), as well as an extensive bibliography.

Newtonian Mechanics

uk: Математика, природничі науки

uk: Фізика, Астрономія

description: This book provides an introduction to the basic concepts of Newtonian Mechanics. Great emphasis is placed on the structure of the theory and its logical coherence. The presentation attempts to highlight Newtonian Mechanics as a comprehensive physical theory that can lead to verifiable predictions. The mathematics involved in the theory are not presented in a separate chapter, as if they were a special tool to be used in the presentation of the various topics. On the contrary, each new mathematical idea is constructed as the best way to study a new physical concept. The aim is to show as clearly as possible the direct connection between mathematics and physical reality. Despite the emergence of mathematics as a basic language in the study of nature, we recommend the use of computers in solving problems, but in such a way as to exercise physical intuition. Furthermore, the numerical calculation of a physical problem leads in a tangible way to a deeper understanding of all aspects of the corresponding topic. The book covers topics (Green's functions, delta functions, symmetries) that are not usually found in introductory engineering textbooks because they are considered technical topics that are more advanced than those covered in an undergraduate course. We believe that the use and discussion of these topics at a very basic and therefore very simple level will help students understand difficult concepts and use them to easily solve problems that are particularly challenging from a mathematical point of view. The book is supplemented with numerous exercises (most of which are original and not copies of exercises from the international literature) aimed at encouraging students to seek/develop their own ways of analyzing physical problems.

description: This book deals with a contemporary issue with technological, legal and social implications, the issue of the protection and management of Intellectual Property Rights in the Information Society. In today's digital world, even the most routine access to information inevitably involves making a copy. For example, software for viewing a web page (web browser) first creates a copy of the web page in memory and stores it in the history of addresses that the user has visited. This operation is done for better access to the information but in practice it is a reproduction that involves the concept of copyright protection. Also, when data is transferred over global networks, a repeated reproduction of the content takes place on network devices, routers and servers. The exclusive right of reproduction is the first and most basic right for the copyright owner of a work. How can this conflict between the desire to provide access and the desire to control copying be alleviated, when for a digital information access and transfer simultaneously implies the production of copies? This book proposes, designs, implements and evaluates original software development techniques and methodologies for the management, protection and exploitation of Intellectual Property Rights in the Information Society. Specifically, the current international situation is analyzed, the available solutions are presented, the shortcomings of these solutions are detected and the new proposed means to deal with the issue are highlighted. For the first time, a complete analysis of the problem of copyright protection and management of digital content is achieved, the entities and their relationships are presented, and the necessary functional and technical specifications are drawn up. Subsequently, the design and development of an information system is presented, which fully satisfies the goals and specifications set. Also, the individual components of the information system that are proposed to be implemented are analyzed and evaluated.

description: This book examines basic issues concerning the synchronic and diachronic dimension of languages, with emphasis on the Greek language. First, we briefly review linguistic and grammatical research from antiquity to the present day. Then we approach the different levels at which linguists usually analyse languages: phonological, morphological, morphophonological, syntax, vocabulary-signification. For each level the general concepts and elements of the Greek system are given. The levels are accompanied by examples (from Greek and other languages), pictures and diagrams. As far as longitudinal linguistics is concerned, a historical review of attempts to compare languages and interpret linguistic changes from antiquity to the present day is given. The main features of language evolution, namely variation and differentiation, are highlighted. The principles and methods of historical/chronological and comparative linguistics are examined. The issue of degrees of affinity between languages and their classification into language families is discussed. It then considers issues of etymology and paretymology, which can be used in understanding the spelling and meaning of words. The phenomenon of borrowing words and other elements between languages (external borrowing) and from an earlier form of the language or a variety of it to another (internal borrowing) is also presented. Finally, phonological and morphological changes in the history of Greek and in particular the changes in the vowels of roots and suffixes are examined, with emphasis on examples from ancient and modern Greek (τρέχω-trochos).

description:
The term "liquid crystal" describes the state of matter, whose properties are between the isotropic liquid and  crystalline solid. Since their discovery, at the end of the 19th century, by F. Reinitzer (1888) and O. Lehmann (1889), there have been thousands of compounds that they present this unusual and at the same time very interesting liquid crystals or mesophase state of matter. The fundamental condition for liquid crystallinity is that the molecule presents a high degree of anisotropy in its shape.
Anisotropy in shape also leads to dielectric anisotropy and optical anisotropy, which are the main features in imaging technologies. Depending on the nature of the molecular structure, a compound may pass through one or several different liquid crystalline phases, characterized by order and symmetry, before the conversion in an isotropic liquid.
There are two general categories of liquid crystals, thermotropic liquid crystals that occur through thermal transitions and lyotropic liquid crystals that occur from the solubility variation. The molecules of liquid crystals are mainly distinguished either in rod-like or calamitic or discotic.
For the past 40 years, liquid crystals have been applied in optical displays, known as liquid crystal displays or LCDs. Today, liquid crystals rule the roost in the global flat panel display market, from laptop to desktop displays to more recently, with penetration into the large television market. Because of the technological advancement in this field, researchers specializing in Liquid Crystal Science and Technology are oriented towards new applications through the characteristic and strong electro-optical properties of liquid crystals.
The book is divided in 9 chapters, including:
In the first chapter, the states of matter, a brief introduction to liquid crystals, an overview on the discovery of liquid crystals and a brief historical overview.
In the second chapter, the classification of all categories and types of liquid crystals.
In the third chapter, polymeric liquid crystals.
In the fourth chapter, a brief review regarding the chemistry of thermotropic liquid crystals and the
effects of their structural groups on the type of mesophase and the methods of their characterization.
In the fifth chapter, the main theoretical approaches in relation to the formation of liquid crystalline phases.
In the sixth chapter, the optical and other physical properties of thermotropic liquid crystals.
In the seventh chapter, the effect of electric and magnetic fields on liquid crystals.
In the eighth chapter, the factors that influence the selective reflection from cholesteric or chiral nematic mesophase.
In the ninth chapter, the applications of liquid crystals.

The hydrological components of water balance at wetlands and lakes (rainfall, runoff, evapotranspiration, groundwater and interaction of groundwater and wetlands) are described. The water quality characteristics and the changes of them in space and in time are also described using mathematical formulas. Equations and relationships which connect the water quality and the hydrological processes are also described. In two chapters the characteristics and the principles of artificial wetland design are presented. At the last chapter mathematical models that describe the water quality and the eutrophication in lakes and wetlands are described and the basic equations that used in one of these models are also presented. At the appendix a dictionary and glossary of terms that used in wetland and lake hydrology is tried to present.

description:
Much is said and written about hydroclimatic hazards: storms, floods, droughts. Such hazards have existed and will always exist, while the usual scaremongering on them is of little help to avoid them. Instead, what is needed is a cool look at risk, based on measurement data, using scientific methodology, and ultimately employing technology in the service of reducing hazards and their consequences.

This is attempted in the book. Much of it is devoted to the theory of stochastics —the mathematical language for analysing extremes. Stochastics is a scientific area broader than statistics —according to the definition adopted in the book, statistics is part of stochastics. Another part is the theory of stochastic processes, in which time has a hypostasis that is typically absent in statistics. Thus, statistics is in relation to stochastic what statics are in relation to dynamics. The commonly used classical statistics (based on the assumption of independence) is a special case of stochastics and, as the book proves, is inappropriate for the subject. This does not mean that statistics are abandoned or underrepresented in the book. On the contrary, several new developments are presented —most notably the new tool of knowable moments, which have two relevant characteristics: they are closely connected to extremes and their estimation is unbiased in the framework of classical statistics or involves small (and determinable) bias in stochastic processes with dependence in time, whilst the bias in the estimation of classical statistical moments can be huge.

The new theoretical analyses are supported by mathematical proofs, which, to improve readability, are contained in a number of appendices in each of the 10 main chapters of the book. Along with the development of the theory, the book is oriented to the application, which is supported by a variety of examples, usually standing out as parenthetical sections or Digressions, as well as by tabulations of mathematical formulae that are used for each task.

uk: Математика, природничі науки

description:
This book is addressed to undergraduate and graduate students of science and engineering schools. A main subject of teaching in these schools is the understanding of various physical phenomena through their mathematical modelling. The latter is done by formulating them as boundary or initial-boundary value problems for differential equations with partial derivatives.  In most cases, we cannot find an exact solution explicitly, therefore we rely on the implementation of numerical methods on computers to construct approximations.
Here, we consider boundary value problems for elliptic differential equations in one or two spatial variables and initial and boundary value problems for the heat equation, the wave equation and the transport equation in one or two spatial variables.
For the numerical solution of the above problems, we consider finite difference methods and finite element methods. For the discretization in space, we employ either finite difference methods or finite element methods, and for the discretization in time we use various finite difference methods.
We show various theoretical results concerning the stability, consistency and convergence of the above numerical methods. In addition, we present numerical examples supplemented by graphs and tables of results. At the end of each chapter there is a series of exercises for the prospective student to better understand the corresponding chapter.

description: The book is a publication, translation, and detailed commentary on one of Aristotle's most important texts. In the second book of "Physics," Aristotle sets out his theory of causality, which he adopts for the study of natural phenomena (the well-known four Aristotelian causes), opposes the mechanistic determinism of the Atomist philosophers, and proposes his own teleological perspective. He also touches on the question of whether there is such a thing as chance in nature. Any exposition of Aristotle's natural philosophy begins with an analysis of this text, which is also a turning point for later natural philosophy (until the emergence of modern physics in the 17th century). The book is structured as follows: 1. An extensive introduction, which places Aristotle's approach in the context of the intellectual environment of the 4th century BC. 2. Aristotle's ancient text with its modern Greek translation, accompanied by a limited number of explanatory notes. 3. A detailed interpretation of Aristotle's text, structured according to the subheadings of the ancient text. 4. Bibliography, glossary, tables, and indexes.

description: The book aims to provide an overview of the different aspects that shape contemporary theory and practice of museum education and to discuss issues relating to the nature of learning in museums. The book is based on multiple theoretical perspectives and presents multiple examples from the Greek and international museum experience. The Introduction (chapter 1) presents a general overview of museum education today and introduces the three thematic sections of the book. In the first section entitled: Theoretical approaches: Methods and Objectives (chapters 2, 3) the theoretical background of museum education is analyzed, focusing on educational theories of knowledge, learning and teaching and the specific characteristics of learning in museums. Then, museum educational aims as well methods and activities used to facilitate visitor experiences are analyzed. The second section of the book – Museum learning and audiences (chapters 4, 5, 6, 7) – is dedicated to the multiple audience groups that museums address in order to achieve their educational role. This section discusses the relationship between museums and schools, leisure activities targeting different target groups (families, children, adults, seniors, etc.) as well as strategies for reaching audiences that do not have access to museums. This section ends with a chapter on audience research and evaluation as key tools for achieving visitor-centred learning processes. The third part of the book – Media and spaces of Learning and Experience (chapters 8, 9, 10) – examines teaching resources used in museum education. In particular, it analyses museum space as a learning environment, but also the educational materials (printed materials, hands-on collections etc.) produced by museums, as well as the digital media that are increasingly used in order to provide museum-learning experiences.

description:
The book develops the Galois Theory of field extensions. The theory of polynomials and the determination of their roots is a subject widely used in all branches of mathematics and their applications. In this book, we develop the theory of polynomials over a field and the process of finding polynomial roots, based on the theory of field extensions, particularly finite-dimensional extensions. Automorphisms of fields play an extremely important role, and their extensive study precedes the proof of the Fundamental Theorem of Galois Theory. The theory of finite fields is developed, and methods for finding irreducible polynomials over such fields are presented.
We also present applications of Galois Theory to solving polynomial equations over both fields of characteristic zero and finite fields. The classical unsolved problems of constructability with a straightedge and compass from antiquity are discussed. Sufficient and necessary conditions for the constructability of regular polygons are also provided. A proof of the Fundamental Theorem of Algebra is presented. Galois Theory culminates in solvability theory, offering complete information on when algebraic formulas exist for the roots of a polynomial, i.e., when a polynomial is solvable by radicals. Throughout the text, we highlight the role of permutation groups in the solvability of polynomials and provide numerous examples.
In the appendix, we include the necessary material on Group Theory and Ring Theory. A brief historical overview is given at the beginning of the text.
Exercises play a crucial role in reinforcing the material, and extensive hints are provided. An extensive bibliography is included at the end.

description: This book is adressed to undergraduate students of Polytechnic and Geological Schools who are studying Mining Research, as well as teachers and professionals in the mining field who wish to deepen their knowledge of specific technical issues in the subject. The book covers topics such as the discovery of deposits, the calculation of the quality and quantity of reserves, and the collection of data for calculating their value, i.e., the economic benefit that will result from their exploitation. First of all, the analysis of mining exploration as an investment process with a high degree of business risk is documented, and dynamic planning is developed as a methodology for optimizing the process followed. Next, the basic types of deposits, the various systems for classifying reserves by category, and the determination of their industrial value are described. This is followed by a description of the geochemical and geophysical methods used in the initial stages of exploration, as well as the direct methods involving the direct sampling of mineral-bearing sections, either through drilling or mining. The issues of the performance of a research grid and the determination of the optimal density of research projects are analyzed. A review of reserve estimation methods is provided, and geostatistics is presented in detail as the most widely used method. Finally, reference is made to the data required for the preparation of the necessary studies, such as the technical-economic study, the feasibility study, and the environmental impact study, in order to evaluate and implement the investment plan.

Η χρήση της Μαθηματικής Λογικής ως εργαλείο αφαίρεσης για περιγραφή υπολογισμών και η εκμετάλλευση των αποδεικτικών διαδικασιών της, οδηγούν σε συμπαγή προγράμματα τα οποία βρίσκουν εφαρμογές σε πολύπλοκα και ενδιαφέροντα πεδία, όπως είναι η Τεχνητή Νοημοσύνη και το Σημασιολογίκο Ιστό. Όμως, αυτή η υψηλού επιπέδου προσέγγιση στον προγραμματισμό δημιουργεί προβλήματα σε εκείνους που πρώτη φορά έρχονται σε επαφή με τον ΛΠ , αφενός γιατί απαιτεί να υιοθετήσουν μια δηλωτική προσέγγιση στην ανάπτυξη προγραμμάτων "ξένη" προς αυτή των κυρίαρχων γλωσσών, και αφετέρου, γιατί απαιτείται η εκμάθηση τεχνικών αναπαράστασης και επίλυσης προβλημάτων που αν και είναι γενικά εφαρμόσιμες στον προγραμματισμό, δεν χρησιμοποιούνται συχνά στις υπόλοιπες σχολές, με κλασικό παράδειγμα την αναδρομή. Το παρόν βιβλίο φιλοδοξεί να καλύψει τις παραπάνω απαιτήσεις και να αποτελέσει το βασικό σύγγραμμα για οποιονδήποτε επιθυμεί να εντρυφήσει στην τέχνη και στις τεχνικές του ΛΠ.

description:
The book provides a concise yet systematic exposition of the methodologies for analysing and designing mass-transfer processes. The first part develops mass and energy balances and applies them to a variety of examples of industrial relevance. These examples serve as an informal introduction to the main physical processes. Transient balances are covered in a separate section and are combined with some preliminary ideas of automatic control. Next, the equilibrium thermodynamics of liquid/vapour mixtures are reviewed, followed by the description of mass transfer in multiphase systems. Thus, the necessary background for the analysis and design of physical processes is complete.
In the second part of the book, the main physical processes are introduced. Process equipment is classified according to the mode of contact of interacting streams, as multi-cascade or continuous. Fractional distillation of a binary mixture is analyzed as the representative example of the first category, and gas absorption in a packed column is an example of the second category. Humidification processes are considered next in significant detail because they are central to many engineering applications (cooling towers, air-conditioning, drying etc.) and serve as a paradigm of simultaneous heat and mass transfer. Finally, liquid-liquid extraction and gas adsorption to a porous solid are given introductory consideration, providing examples of additional processes that may be analyzed with similar engineering methodologies.

description: This book is a thorough and analytical presentation of Galois Theory. After recalling basic notions of ring theory, Gauss Lemma is being proved for unique factorization domais. We also present and prove a generalization of Eisenstein’s Criterion for integral domains. We study algebraic, separable and normal extensions of fields. Apart from this we prove the existence of algebraicaly closed fields and of the algebraic hull of a field and characterize Galois extensions via the Galois theory of group actions on sets and we also study finite Galois extensions.  Furthermore we prove Artin’s Lemma and present a procedure for determining fixed fields (relative to a subgroup of the Galois group) of simple finite field extensions. We also study the field of rational functions as an extension of the field of symmetric rational functions. Using the theory of symmetric polynomials, we obtain the formulas describing the roots of the cubic and biquadratic polynomials. We prove the Fundamental Theorem of Galois Theory and the Fundamental Theorem of Algebra. We study extensively the finite fields. We give and prove necessary and sufficient conditions in order to be a complex number constructible by compass and lineal. We also give and prove necessary and sufficient conditions in order to be a regular n-gon constructible by compass and lineal. We study the splitting fields of cyclotomic polynomials and of polynomials of the form x^n-a. We prove Galois Theorem of the solvability of a polynomial by radicals. We determine the Galois groups of cubic and biquadratic polynomials. Using relative resolvents, we study  the Galois group of a polynomial. Finally we present and study the Weber resolvent which gives a sufficient and necessary condition in order to be solvable by  an irreducible polynomial of fifth degree with rational coefficients. The book contais many non trivial examples and over 365 exercises.

uk: Математика, природничі науки

description:
This is a modern book covering classical Algebraic Number Theory, a branch of Number Theory originally motivated by Fermat’s conjecture.
The book begins by providing the formulations of the respective theorems and their proofs in the most simple, non-trivial setting, namely that of quadratic fields.
In the following chapters basic notions are, including for example Integral Dependence, Dedekind Rings, Norm of the Elements, Trace, Integral Basis, Norm of Ideals, Class Numbers, Law of Analysis of Prime Ideals, Minkowski’s Theorem, the Finiteness of the Class Number as well as Dirichlet’s Unit Theorem. These contents correspond to the undergraduate part of a basic course on Algebraic Number Theory.
The following chapters cover Hilbert’s Ramification Theory, the General Reciprocity Law for Abelian Extensions of Number Fields (note that for the non-Abelian case, the problem is in general open and a part of the so called “Langlands Philosophy”), the Discriminant and Different theorems and the Kronecker-Weber theorem. These are more advanced subjects and in our view suitable for an advanced undergraduate course.
Finally the last two chapters return to Fermat’s Conjecture, study the results of Kummer and describe the complete proof of the Conjecture through the results of Frey, Serre, Ribet and Wiles. This last chapter is mostly based on specific methods and techniques of the so called Arithmetic Algebraic Geometry, and contains elements from the Theory of Elliptic Curves, Modular Forms and Galois Representations.
The book contains numerous examples, a large number of exercises and extensive bibliography.
As a prerequisite we expect that the reader has some basic knowledge of Galois Theory and the contents of the Appendix (chapter XIII) of the book.
We aspire that the present book will be particularly useful not only for students but for anyone interested in getting a glimpse of the beauty of Number Theory.

The geometric properties of such sets are encoded inside the rings of functions that are naturally defined on such sets. In this book we develop both the more abstract theory of schemes and the classical approach in terms of Riemann surfaces and algebraic function fields over a field of arbitrary characteristic.

description: Based on extensive primary sources from various countries, the book tries to analyse Greece’s incorporation into Euro-American strategic planning and initiatives about the organisation of the European defence from the end of the 1940s until mid-1990s. More precisely, focuses on Greece’s efforts to accede into military alliances and treaties forged and signed from 1947 onwards with a view of shaping the defence of Western Europe (Brussels Treaty, European Defence Community, NATO, Western European Union). These efforts were viewed askance or even opposed by the European States either out of fear of any Soviet reaction or because this move was inconsistent with their own geostrategic planning for the Eastern Mediterranean region; or because they did want the extension of the transatlantic alliance so far and so close to the Warsaw Pact or, during the 1990s, because they did not want the alliance to became embroiled in the Greek-Turkish conflict. Greece’s definitive inclusion into the Western European Union in 1995 was linked to such conditions that in fact annulled the expected benefits for Greece’s defence (mainly against Turkey). Therefore, it was received by Athens lukewarm despite the fact that completed efforts undertake over many decades which had consumed huge diplomatic and political capital.
