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: Το βιβλίο αποτελεί ένα εγχειρίδιο σχετικά με το ζήτημα της μνημειακής προστασίας, αποκατάστασης και διαχείρισης. Εξιστορεί το πως οι διάφορες κοινωνίες αντιμετώπιζαν τα κατάλοιπα του παρελθόντος από τα κλασικά χρόνια έως το τέλος του 18ου αι., οπότε και αναφαίνεται η σύγχρονη αντίληψη της μνημειακής προστασίας, η συνειδητοποίηση δηλαδή της ανάγκης διατήρησής τους, ως φορέων μνήμης και πνευματικών αξιών απαραίτητων για τη ψυχική ισορροπία των συγχρόνων και μελλοντικών γενεών. Εξιστορείται επίσης η διάδοση αυτής της νέας αντίληψης στην Ευρώπη και οι διάφορες έμπρακτες εφαρμογές της, από τις οποίες απορρέουν και οι διάφορες θεωρητικές προσεγγίσεις που διαδοχικά διαμορφώνονται: η κλασικιστική αντίληψη της προστασίας των μνημείων, η ‘σχολή’ της ολικής στυλιστικής αποκατάστασης, το Κίνημα εναντίον της Αποκατάσταασης των Μνημείων, οι προσεγγίσεις της «φιλολογικής αποκατάστασης» και «ιστορικής αποκατάστασης», η προσέγγιση του ζητήματος από τους A.Riegl και G.Giovannoni, ο Χάρτης των Αθηνών του 1931. Στα επόμενα κεφάλαια παρακολουθείται η εξέλιξη των αντιλήψεων μετά τον Β΄Παγκόσμιο Πόλεμο, αφενός έως τον Χάρτη της Βενετίας του 1964, του ισχύοντος έως σήμερα κύριου διεθνούς κανονιστικού κειμένου αρχών επέμβασης στα μνημεία, αφετέρου κατά το τελευταίο τέταρτο του 20ου αι. και τις αρχές του 20ου, όταν νέες αντιλήψεις αναφύονται ως απόρροια της παγκοσμιοποίησης του ζητήματος. Παράλληλα παρατίθεται και η ιστορία της μνημειακής προστασίας στην Ελλάδα, οι τρείς κύριες περίοδοί της (1. Από την ίδρυση του νεοελληνικού κράτους έως τον Β΄Παγκόσμιο Πόλεμο, 2. Από το τέλος του Β΄ΠΠ έως τη Δικτατορία του 1967 και 3. Από το 1974 έως σήμερα), οι κυριότερες επεμβάσεις, οι πρωταγωνιστές, το νομοθετικό και διοικητικό πλαίσιο. Το βιβλίο ολοκληρώνεται με ειδικά κεφάλαια για την, μετά το 1975, αναστήλωση της Ακρόπολης και για την ορολογία της μνημειακής αποκατάστασης (και στα αγλλικά, γαλλικά και ιταλικά), καθώς και με πλούσια βιβλιογραφία.

Νευτώνεια Μηχανική

uk: Математика, природничі науки

uk: Фізика, Астрономія

description:
Στο βιβλίο αυτό γίνεται μια εισαγωγή στις βασικές έννοιες της Νευτώνειας Μηχανικής. Δίνεται μεγάλη έμφαση στη δόμηση της θεωρίας
καθώς και στη λογική συνοχή της. Η παρουσίαση προσπαθεί να αναδείξει τη Νευτώνεια Μηχανική ως μια ολοκληρωμένη φυσική θεωρία,
η οποία μπορεί να οδηγήσει σε ελέγξιμες προβλέψεις. Τα μαθηματικά που εισέρχονται στη θεωρία δεν αποτελούν ξεχωριστό κεφάλαιο,
σάν να πρόκειται για κάποιο ιδιαίτερο εργαλείο που θα χρησιμοποιηθεί στην παρουσίαση των διαφόρων θεματικών ενοτήτων.
Αντιθέτως, κάθε νέα μαθηματική ιδέα κατασκευάζεται ως ο καλύτερος τρόπος μελέτης κάποιας νέας φυσικής έννοιας. Επιχειρείται έτσι
να φανεί όσο το δυνατό πιο ανάγλυφα η άμεση συσχέτιση των μαθηματικών με τη φυσική πραγματικότητα.

Παρά την ανάδειξη των μαθηματικών σε ρόλο βασικής γλώσσας στη μελέτη της φύσης, προτείνουμε τη χρήση υπολογιστή
στην επίλυση των προβλημάτων με τρόπο όμως τέτοιο ώστε να ασκηθεί η φυσική διαίσθηση. Περαιτέρω ο αριθμητικός υπολογισμός
ενός φυσικού προβλήματος οδηγεί με απτό τρόπο στην εμβάθυνση της κατανόησης όλων των πτυχών του αντίστοιχου θέματος.

Στο περιεχόμενο του βιβλίου υπάρχουν θέματα (συναρτήσεις Green, συναρτήσεις δέλτα, συμμετρίες)
τα οποία δεν συναντώνται συνήθως σε εισαγωγικά βιβλία Μηχανικής λόγω του ότι θεωρούνται τεχνικά θέματα που αφορούν ένα
πιο προχωρημένο επίπεδο από αυτό ενός προπτυχιακού μαθήματος. Πιστεύουμε ότι η χρήση και η συζήτηση των αντικειμένων
σε ένα πολύ πρωταρχικό και άρα πολύ απλό επίπεδο θα βοηθήσει τον φοιτητή να κατανοήσει δύσκολες έννοιες, αλλά και να
τις χρησιμοποιήσει για να εξάγει εύκολα αποτελέσματα σε προβλήματα που παρουσιάζουν ιδιαίτερη μαθηματική δυσκολία.

Το βιβλίο συμπληρώνεται με πλήθος ασκήσεων (οι περισσότερες από αυτές είναι πρωτότυπες και δεν αποτελούν αντίγραφα
ασκήσεων από τη διεθνή βιβλιογραφία) που στόχο έχουν να παιδέψουν τον φοιτητή να αναζητήσει/κατασκευάσει ο ίδιος τρόπους
ανάλυσης φυσικών προβλημάτων.

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: Το βιβλίο αυτό εξετάζει βασικά θέματα σχετικά με τη συγχρονική και διαχρονική διάσταση των γλωσσών, με έμφαση στην ελληνική γλώσσα. Κατ' αρχάς αναφέρουμε συνοπτικά τη γλωσσική και γραμματική έρευνα από την αρχαιότητα μέχρι σήμερα. Στη συνέχεια προσεγγίζονται τα διάφορα επίπεδα στα οποία αναλύουν συνήθως τις γλώσσες οι γλωσσολόγοι: φωνολογικό, μορφολογικό, μορφοφωνολογικό, σύνταξη, λεξιλόγιο-σημασία. Για κάθε επίπεδο δίνονται οι γενικές έννοιες καθώς και στοιχεία του συστήματος της ελληνικής. Τα επίπεδα συνοδεύονται με παραδείγματα (από την ελληνική και άλλες γλώσσες), εικόνες και σχεδιαγράμματα. Όσον αφορά στη διαχρονική γλωσσολογία, γίνεται ιστορική ανασκόπηση των προσπαθειών για σύγκριση γλωσσών και ερμηνεία γλωσσικών μεταβολών, από την αρχαιότητα μέχρι σήμερα. Επισημαίνονται τα βασικά χαρακτηριστικά της εξέλιξης των γλωσσών, που είναι η μεταβολή και η διαφοροποίηση. Εξετάζονται οι αρχές και οι μέθοδοι της ιστορικής/διαχρονικής και συγκριτικής γλωσσολογίας. Συζητείται το θέμα των βαθμών συγγένειας μεταξύ γλωσσών και της ταξινόμησής τους σε γλωσσικές οικογένειες. Κατόπιν εξετάζονται θέματα ετυμολογίας και παρετυμολογίας, τα οποία μπορούν να αξιοποιηθούν στην κατανόηση της ορθογραφίας και της σημασίας των λέξεων. Επίσης, παρουσιάζεται το φαινόμενο του δανεισμού λέξεων και άλλων στοιχείων μεταξύ γλωσσών (εξωτερικός δανεισμός) αλλά και από παλαιότερη μορφή της γλώσσας ή ποικιλία αυτής, σε άλλη (εσωτερικός δανεισμός). Τέλος, εξετάζονται φωνολογικές και μορφολογικές μεταβολές στην ιστορία της ελληνικής και ειδικότερα οι μεταπτώσεις των φωνηέντων των ριζών και των επιθημάτων με έμφαση σε παραδείγματα από την αρχαία και τη νέα ελληνική (τρέχω-τροχός).

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.

description: The book of “Environmental hydrology of lakes and wetlands” presents the fundamental characteristic and properties of wetland and lakes and the importance and the role of them in the aquatic systems and the cycle of life. 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:
Το βιβλίο είναι έκδοση, μετάφραση και αναλυτικός σχολιασμός ενός από τα πιο σημαντικά κείμενα του Αριστοτέλη. Στο 2ο βιβλίο των "Φυσικών" ο Αριστοτέλης εκθέτει τη θεωρία της αιτιότητας που υιοθετεί για τη μελέτη των φαινομένων της φύσης (τα γνωστά 4 αριστοτελικά αίτια), αντιτίθεται στη μηχανιστική αιτιοκρατία των Ατομικών φιλοσόφων και προτείνει τη δική του τελεολογική οπτική. Θίγει επίσης το ζήτημα του κατά πόσον υπάρχει έννοια τύχης στη φύση.
Οποιαδήποτε έκθεση της φυσικής φιλοσοφίας του Αριστοτέλη εκκινεί από την ανάλυση αυτού του κειμένου, ενώ αποτελεί σημείο τομής για τη μεταγενέστερη φυσική φιλοσοφία (μέχρι την ανάδυση της σύγχρονης φυσικής κατά τον 17ο αιώνα).
Το βιβλίο θα είναι διαρθρωμένο:
1. Σε μια εκτενή εισαγωγή, όπυο τοποθετείται η προσέγγιση του Αριστοτέλη σε σχέση με τον διανοητικό περίγυρο του 40υ π.Χ. αιώνα
2. Στο αρχαίο κείμενο του Αριστοτέλη με τη νεοελληνική του μετάφραση, συνοδευμένη από έναν περιορισμένο αριθμό ερμηνευτικών σημειώσεων.
3. Αναλυτική ερμηνεία του κειμένου του Αριστοτέλη διαρθωμένη σύμφωνα με τα υποκεφάλαια του αρχαίου κειμένου
4. Βιβλιογραφία, γλωσσάρι, πίνακες και ευρετήρια.

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.

This book is addressed to IT teachers of all levels of formal education to IT teachers of technical education as well as to IT teachers aimed at people with special skills.
The book deals with the didactics of Informatics both in the context of general and in the context of special education. Using well-known learning theories and modern teaching techniques and taking into account the extensive use of the Internet by both students and teachers, we attempt to document a comprehensive guide for teaching IT using web 2.0 tools and social networking tools.
At the same time, an important reference is made to mental models and representations in the teaching of Informatics, as well as to their didactic importance in special education. Considering the importance of technological literacy (even today) and the ethical use of IT, a section of the book also refers to the development of IT skills using web 2.0 tools.
Recognizing educational scenarios as an inherent component of the educational package that accompanies a computing environment, we embrace them and emphasize their contribution to the teaching of informatics. Moreover, extensive reference is made to the utilization of teaching scenarios in both general and special education with the use of web 2.0 tools and relevant examples of the implementation of educational scenarios are given.
Finally, reference is made to the evaluation perspectives of web 2.0 tools and social networks both in terms of educational software and in terms of their satisfactory utilization in the teaching of IT in general and special education.

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:
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 presentation of Galois Theory. After recalling basic notions of ring theory, we prove Gauss Lemma 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. We prove the existence of algebraicaly closed fields and of the algebraic hull of a field. We characterize Galois extensions via the theory of group actions on sets and we also study finite Galois extensions. 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 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 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 radicals 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.

description: This book will enable general education teachers, special educators, specialist scientists and therapists, parents/guardians, carers and social partners to more effectively address the special needs of people with intellectual disabilities. In particular, it focuses on describing the developmental course of the social, emotional and communicative characteristics of people with intellectual disabilities and especially of people with Down syndrome. Extensively demonstrates appropriate social skills and targeted intervention strategies in an inclusive educational field. Emphasizes the necessary adaptations to the curriculum through evidence based practices in support of positive social behavior. The present issues are important and we believe that the present work comes to fill a gap in the field of studying the social development of children with intellectual disabilities and Down syndrome in general education. Adaptive and social skills seem to help people with intellectual disabilities to interact appropriately in their familiar environment and to generalize their social skills in new environments. During adolescence, interactions and close, quality friendships between peers become increasingly important for personal and social well-being. The role of the family in the successful inclusion of the child with intellectual disability and Down syndrome in the general school is also crucial.

description: The Handbook of Clinical Optometry has been designed to facilitate undergraduate and postgraduate students in Optics & Optometry. The aim is to present the latest developments in eye imaging equipment and the steps to be followed for a complete optometric examination. Specifically, it includes the protocol for a complete optometric examination which presents the objective examination of the refractive state of a patient through retinoscopy or automated refraction. It also analyzes the procedure of subjective refraction using a simple trial frame and trial lenses or using a phoropter. The slit lamp is presented, and its techniques for assessing the physiology of the eye and the corneal topography is analyzed with the presentation of modern topographers and its use in the detection of keratoconus. Reference is made to special imaging techniques such as optical coherence tomography (AS-OCT / POST-OCT), and modern OCT angiography. Imaging techniques also include ocular biometry, A-scan, B-scan ultrasound, UBM - IOL-Master, confocal and specular microscopy, direct and indirect ophthalmoscopy and the use of a non-mydriatic camera for retina observation. The perimetry technique used to evaluate the visual fields is described and a comparison is made between known perimeters as well as evaluation of their findings. The protocol also includes contrast sensitivity testing, color vision testing with the corresponding diagnostic tests, tonometry, gonioscopy, electrophysiological methods of vision examination with EOG, ERG, and VEP evoked potentials and finally reference is made to stereoscopic binocular vision and its testing techniques. Finally, all the necessary diagnostic tests are presented in a preoperative examination before eye surgeries and a small report on pediatric optometry. The handbook is completed with basic knowledge of ophthalmic lenses, such as aspheric, multifocal and prism.

description: The book describes fundamental concepts of bank management and new trends in the banking industry. Banks face increasing challenges from the globalization of money and capital markets, the introduction of new technologies, the emergence of financial crises, the changing climatic conditions, and the outbreak of pandemics (e.g., Covid-19), which directly affect their operation and long-term survival. These revolutionary changes directly challenge traditional banking strategies, requiring the adoption of modern crisis and risk management techniques in a rapidly changing financial landscape. The book introduces the financial system and its structure (central bank, commercial banks, investment banks, etc.), and presents the strategic role of banks. Here the basic mechanisms of banking, the intermediary nature of banks, and the evaluation of their position in the financial system are analyzed. In addition, the concepts, principles, and methodologies of banking marketing are introduced, where the traditional and modern tools for the promotion of banking services are developed. Also, the accounting statements of banking institutions, their asset and liability management techniques, and their financial ratios are presented. In addition, the policy of bank lending is analyzed, in conjecture to credit risks (“red loans”). Also, the most important strategies of banking institutions are discussed, such as the realization of acquisitions & mergers, the creation of financial groups, and the use of new technologies, where their effects on the traditional banking functions are evaluated, especially their effects on the retail banking networks. In addition, the concept of crises is explained, and it is shown how crises affect banking institutions and their strategies. Also, the phenomenon of international expansion of banks and the different forms of their internationalization are investigated. The whole analysis specializes in the Greek economy and the domestic banking system.

description: This book is intended for teaching, mainly at graduate level but it can be used at advanced undergraduate level too. At the beginning fundamental concepts of Analytical Mechanics are introduced, generalized coordinates, constraints, displacements, virtual displacements, virtual work.  Then Lagrange’s formalism follows where d’ Alembert’s principle is introduced , the constrain forces, the inverse problem of Mechanics.  Next Hamilton’s principle is described  and  elements of  the theory of  variations. Applications to General Relativity follow. Problems with boundary conditions for free boundaries are discussed. The principle of gravity wave detection  is given.   We refer to the path integral approach  of quantum mechanics. The idea of symmetries is introduced with theorems of conservation for discrete systems. Motion in a Schwarzschild  field is studied. The lagrangian formulation in special relativity follows.  We continue next to the Hamiltonian formalism, with Hamilton’s equations. We refer to Ostrogradsky’s theorem.  The canonical transformations are introduced and the generating function of the transform is given.  The Poisson brackets follow with the equations of motion with these brackets.  Then we study the infinitesimal canonical transformations together with the corresponding conservation theorems.  We say something about quantization. The concept of Dirac’s brackets is given and their relation to quantization.  The method of Hamilton-Jacobi is studied, and the concept of actions-angles as canonical variables is introduced.  The Theory of Classical Fields is the next subject together with Noether’s theorems for fields. The spontaneous symmetry breaking in classical physics is presented. The theory of disturbance is analyzed and the concept of adiabatic invariance is introduced. An introduction to Non Linear Dynamical Systems is given including parametric resonance and classical chaos. A special subject treated is self-excitation – synchronization. This is observed naturally in several phenomena. At the end, several appendices exist where a detailed analysis of various subjects is given that completes the one given in the chapters of the main book.

description: Biomimetics draws inspiration from the properties of organisms that live in nature, in various habitats, and deals with the simulation of their characteristic properties. Structures and properties from the living matter of nature (e.g., hydrophobic, optical, thigmotropic, tactile), which have been proven to be adapted to long-term environmental stress, revealed by research and used by technology, do create jobs, useful and innovative products, for the benefit of human activity. Internationally, this is a rapidly growing scientific specialization that encourages interdisciplinarity, interaction of ideas, novelties and bioinspiration. Biomimicry is linked to the deceptive imitation of an organism's characteristics by another organism for deception, attraction, or defense; for example, flowers of some plants mimic, as they open and display, certain insects in order to attract them. Also, several insects mimic the foliage of trees and shrubs in order to avoid being noticed by consumers. This e-book presents properties of living organisms that are a "cast" for technology, innovative aspects of research, technological achievements, and future technological challenges and prospects. In other words, the book "Biomimetics and Biomimics" highlights the pre-existing "information" in the “laboratories” of nature, which is currently implemented in innovative anthropogenic constructions. The technological success of Biomimetics is directly related to the properties of the living matter of nature, which are based on long scale, painstaking scientific research. Results obtained using modern infrastructures, sparked many ideas and subsequent bio-inspired applications. Within each of αabove mentioned topics, nature is conceived as a complex and technologically mediated point of departure for new ways of viewing and making the world. Finally, the topics of biomimetic and biomimicry are coordinated with human life, in an era that is characterized and/or recognized as the threshold-period of climatic change and shortage of energy resources on Earth.

description: Information Theory and Coding Theory have been deeply intertwined since their origins, marked by Claude Shannon’s famous paper “A Mathematical Theory of Communication” in 1948. In contrast, Cryptography, though closely linked to Information and Coding Theories, dates back to ancient times. The distinction among these fields is primarily for technical and educational clarity. This book, intended for both science students and self-learners, focuses exclusively on Algebraic Coding Theory. However, it also aims to illustrate the necessity, power, and elegance of Mathematics. The mathematical prerequisites are modest; a basic understanding of Linear Algebra and Probability, along with some familiarity with polynomials over a field, will suffice as a starting point. Beyond these specific requirements, a general “mathematical maturity” is essential. The material is initially accessible to readers without advanced mathematical expertise, but it gradually increases in complexity, offering opportunities for deeper exploration. Efforts have been made to structure the sections as independently as possible, allowing flexibility in the order of study, whether in a classroom setting or during self-study. For a detailed overview of each chapter, please refer to the book’s table of contents. Each section contains numerous examples and exercises. Throughout the text, you will find prompts like “we can easily see that…,” “it is not difficult to prove that…,” “the proof is left as an exercise…”, along with thought-provoking “why?” questions, encouraging active engagement. At the end of each chapter, a recommended bibliography is provided, encouraging interested readers to delve deeper into the subject matter.

description: Diseases and their treatment, substances that are in our natural environment and can work therapeutically from the beginning of history, synthetic medicines from their first administration to the present day, are the subject of this project. The concepts related to the therapeutic action of drugs, whether synthetic or natural, are mentioned in as simple a form as possible, and information is provided on how to develop new medicinal products as well as the methods used to ensure their safe and effective use. Even in the first decades of the 21st century, 80% of people (as announced by the World Health Organization) base their primary health care on herbal products. The same WHO announcement states that about 21,000 natural products are used for pharmaceutical use. Some of the categories of natural products that have biological effects such as alkaloids, glycosides, amino acids, terpenes, steroids and hormones are the chapters of this book. For reasons of completeness, but also to understand the effect of the structure of substances on their biological effectiveness, in most cases the structural chemical formula of these compounds is mentioned as well as the change in their activity that causes any modification of this structure. Briefly, at the end of the book are presented alphabetically registered and with a small development all the basic concepts and terms that were developed throughout the book.

description:
This book is called to serve the educational needs of the relevant courses within the subject of "Electrical Machines", taught in departments of Electrical & Computer Engineering, as well as other departments of polytechnics of the Higher Education Institutions. It mainly concerns the laboratory practice that accompanies the most common categories of electrical machines of direct and alternating current (D.C. and A.C.), such as single-phase and three-phase transformers, D.C. motors / generators and A.C. motors / generators.
Each laboratory application starts by setting the minimum learning objectives and continues with a brief but necessary theoretical analysis, describing the phenomenon to be examined and studied by the student. Then, the required laboratory equipment for its realization is listed and the process of connections and the necessary steps and measurements are followed in a methodical way. There are also calculations requested during the exercise. In addition, as part of the homework, the student will be asked -among other things- to draw/plot operating curves/graphs that verify the corresponding theory, but also to explain, in the judgment and knowledge gained, specific questions set about the phenomena of electric machines he studied.
Other features of this series of laboratory applications are that a) actually assembled devices of electrical machines are used and b) limited mathematics are used, resulting in greater emphasis on the physical understanding of the relevant theories. It should be noted, however, that the absence of advanced mathematics has not removed the technical rigor. The educational method is mainly experimental and has a direct application, as a result of which it offers enough flexibility to adapt to "energy" courses. In general, the content of this book was mainly guided by the simple but comprehensive analysis that a technical book for students of higher education institutions as electrical engineers towards "energy" direction, should have.

description:
The prospects of cultivation of floricultural products and the levels of their consumption are related, directly or indirectly, to sustainable management and production costs. The future of floricultural crops depends on the implementation of environmental friendly farming practices, and presupposes such practices. These practices are associated with reduced inputs of energy, fertilisers, plant protection products and water, and help reduce pollutants, toxic residues and CO2 footprints. The international protocols and directives presented by international organizations ensure the reduction of the ecological footprint of every operation of production. In this context, the above scenarios aim towards that direction as well as growers being adjusted to contemporary cultivation practices.
This is a textbook for undergraduate students. It includes information and latest research data related to the systematic cultivation and production of floricultural plants. In detail, the textbook is divided into fifteen chapters, which include bibliographic data on a) the physiology of growth and flowering, b) the propagation methods and the management of propagating material, c) the most important diseases and pests that negatively affect growth and production, d) the basic techniques that aid in faster and more qualitative flowering, e) the current status of domestic and international trade, marketing and distribution of ornamental plants and (f) the most important floricultural crops, grown domestically and on a global scale under controlled conditions, or outdoors.

description:
The present book is a textbook and, hence, has not the character of a research and does not claim to be original. For pedagogical reasons, the footnotes are rare and there are no references to non-Greek bibliography. On the contrary, it is full of internal references, from Chapter to Chapter and from Section to Section. It is structured around the interpretation of long passages from great phenomenological texts.

The title of the book is “phenomenology of intersubjectivity” and the subtitle includes four names: Husserl, Heidegger, Merleau-Ponty, and Levinas.
The “Phenomenology of Intersubjectivity” thematizes how the Others are given to us. It investigates which experiences are the most critical in order for the Others to appear as such as well as how these experiences are associated with the way in which we experience our own selves. For, as it will be demonstrated, the Others are always there before ourselves.
The four names correspond to four figures of the phenomenological movement, its two founders and two great French phenomenologists. The debts between them as well as the gaps and the changes of perspective create a unique philosophical discussion that draws readers’ full attention, on condition that they get familiar with the technical vocabulary used (that I have tried to keep to a minimum). If this is not the case, the blame is to be put on the book.

description: This book analyzes in depth a class of techniques applied to the so-called "smart antennas". Smart antennas are a class of antenna arrays, which have the ability to steer their radiation beam toward a desired user, thus enhancing the signal reception from this user, while suppressing the reception of any unwanted signals, which can be transmitted at the same time from other directions and therefore could interfere with the reception of the desired signal. This means that smart antennas have the ability to produce a dynamic radiation pattern, i.e., a radiation pattern constantly changing in real time, so as to optimize the reception of the desired signal and suppress all interference signals. The difficulty in implementing such antennas lies in the fact that users, who are served by modern wireless communication networks (such as 5G or beyond 5G wireless networks), are constantly moving in a real environment, while the need for broadband connection is growing. Therefore, a base station antenna, which receives a number of signals from several users at the same time, must properly shape its radiation pattern, so that at any given moment the main lobe is steered toward the desired signal, while at the same time radiation nulls are placed toward respective directions of arrival of unwanted signals. This process is constantly repeated in real time as users move within the geographical service area. Τhis book provides (1) the mathematical formulation and analysis of the most popular beamforming techniques applied to smart antenna arrays according to the requirements in force, and (2) the mathematical formulation and analysis of the most popular direction-of-arrival estimation techniques applied to signals received by a smart antenna array.

In Europe, Early Childhood Education and Care (ECEC) systems are organized in two basic ways:
1) The facilities are separate for younger children and older children. For children under-3s. focus is given in childcare  and in settings of pre - school education while for older children emphasis is given in educational goals.
2) Unitary settings for the whole age range, up until the start of primary education. Both care and early education form an integral part of the provision in unitary settings.
In most European countries ECEC is provided in two separate types of facilities based on children's ages. This monograph provides an up-to-date analysis of the ECEC systems in European countries, especially for children under-3s. First of all the historical trajectory, organization, and quality of  the ECEC systems in European countries are presented. Moreover the five quality dimensions of the ECEC systems in European countries such as governance and financing, access, staff, educational guidance, evaluation and monitoring are separately presented. The findings reveal that there is still some way to ensure access and quality of the ECEC systems in European countries. Universal access as well as high quality and integration of ECEC services have not been achieved so far in many European countries. The types of ECEC services and their quality differ according to children's age in most parts of Europe. Good quality ECEC for children under age 3 is not available in many European countries yet. Accessibility, availability and affordability for children is considerably better for older children than those under the age of 3. Staff qualification requirements are higher for staff working with older than for those working with younger children. Only a few of European ECEC systems have established evaluation systems for structural and process quality.

description: This monograph contributes to the literature on the development of a community and socially oriented mental health care system. Decades of psychiatric reform in Greece have significantly contributed to the promotion and protection of human rights of persons with mental disorders and to their quality of life. Recently, the community care model has been strengthened by new approaches, such as the recovery model, that places emphasis on the empowerment of persons with extreme mental experiences while acknowledging their personal experiences as sources of knowledge and meaning. This book serves these contemporary approaches, through applying this cutting-edge literature in the specific field of psychosis. The first part consists of a scientifically grounded review of contemporary literature regarding understanding and treating psychosis. The second part presents findings of an innovative research study that utilized a narrative biographical approach to bring forth the testimonies of persons with psychosis. Through the participant testimonies, we trace the life experiences before the emergence of psychosis and the social factors that possibly contributed to it. We also present the ways in which participants experienced, understood and managed their psychotic experiences. Given the dynamic integration of new scientific fields, such as community clinical psychology and the sociology of health and illness, in Undergraduate and Postgraduate Programs of study, this book provides a useful resource for students, researchers and professionals who wish to work in a person-centered direction of understanding and dealing with mental distress and to develop professional practices that support recovery, something that is the declared goal for contemporary mental health professionals.
