Numeri e Crittografia
Number Theory is one of the most classic fields of Mathematics. The numbers he deals with are those that are called natural 0, 1, 2, ... and that we use since childhood to count. Seemingly simple and harmless, they nevertheless hide some of the most difficult and exciting mysteries of the whole of mathematics. Cryptography, on the other hand, is concerned with hiding the content of confidential communications from prying eyes and corresponds to widespread needs in our society. The Theory of Numbers can help Cryptography in these needs, thanks to the mysteries that still surround it. The text gives an account of this link. It first introduces Modern Cryptography, its goals and priorities. He then goes on to expose arguments of Number Theory, with particular reference to the two problems of recognizing prime numbers, and of decomposing a natural into its prime factors; for each of the two issues it provides a vast panorama of the algorithms that deal with it and try to solve it as effectively as possible. In particular, it presents the very recent AKS procedure for recognizing prime numbers. The book then returns to Cryptography and shows how ideas and methods of Number Theory apply to the construction of reliable procedures for the secure transmission of confidential information.
Multiphase Flow Dynamics 3 : Turbulence, Gas Absorption and Release, Diesel Fuel Properties
Volume 3 is devoted to selected Chapters of the multiphase fluid dynamics that are important for practical applications. The state of the art of the turbulence modeling in multiphase flows is presented. As introduction, some basics of the single-phase boundary layer theory including some important scales and flow oscillation characteristics in pipes and rod bundles are presented. Then the scales characterizing the dispersed flow systems are presented. The description of the turbulence is provided at different level of complexity: simple algebraic models for eddy viscosity, algebraic models based on the Boussinesq hypothesis, modification of the boundary layer share due to modification of the bulk turbulence, modification of the boundary layer share due to nucleate boiling. Then the role of the following forces on the matematical description of turbulent flows is discussed: the lift force, the lubrication force in the wall boundary layer, and the dispersion force.
Modelli Matematici in Biologia = Mathematical Models in Biology
This text is addressed first of all to the students of the Specialist Degrees in Biology of the Universities, but it will also be of interest to students of Natural Sciences and Medicine. The topics covered include the most classic mathematical models of biological phenomena (population dynamics, spread of infectious diseases, simple physiology models), but a relevant part of the text is dedicated to the mathematical approach to the theory of natural evolution. The only prerequisites required of the reader are those provided by the basic courses of Mathematics of the Bachelor's Degree in Biology, Natural Sciences or Medicine.
Introduzione al Calcolo Scientifico : Esercizi e problemi risolti con MATLAB = Introduction to scientific computing : Exercises and problem solved with MATLAB
Introduces the fundamental concepts for the numerical modeling of partial differential problems. We consider the classic linear elliptic, parabolic and hyperbolic equations, but also other equations, such as those of diffusion and transport, of Navier-Stokes, and the conservation laws. Numerous physical examples underlying these equations are provided, their main mathematical properties are studied, then numerical resolution methods based on finite elements, finite differences, finite volumes and spectral methods are proposed and analyzed. In particular, the algorithmic and computer implementation aspects are discussed and some easy-to-use programs in C ++ language are provided. The text does not presuppose an advanced mathematical knowledge of partial differential equations: the strictly indispensable concepts in this regard are reported in the Appendix. THE VOLUME is therefore suitable for students of scientific degree courses (Engineering, Mathematics, Physics, Chemistry, Information Sciences) and recommended for researchers from the academic and extra-academic world who want to approach this interesting branch of applied mathematics.
I numeri nel cuore = Numbers in the heart
An extremely varied gallery of ironic reflections on the academic world, of mild anecdotes, of calm provocations, of travel notes, of portraits of famous mathematicians, suspended between joke and seriousness, between dream and reality. Two exquisite fantasies by Arthur Porges and Arthur Koestler open the collection, followed by short stories written by professional mathematicians, who have literature as a hobby, inspired by characters and facts, emotions and fantasies related to the world of mathematics.
Fabbriche, sistemi, organizzazioni : Storia dell'ingegneria industriale = Factories, systems, organizations : A history of industrial engineering
This book examines the origin of the technological and organizational challenges of industry in Europe and the United States and the stages of its theoretical formulation; the creation of the figure of the industrial engineer between the nineteenth and twentieth centuries; and the elaboration of the technological disciplines and of the language and of the fundamental concepts (system, automation, control, optimization, network) of modern industrial engineering. Divided into three chronologically organized parts, each chapter is accompanied by readings, bibliographic information for in-depth study and illustrative sheets of historical, biographical aspects (relating to some great engineers, scientists and philosophers), terminological and mathematical-technical aspects.
Esercizi di finanza matematica = Mathematical finance exercises
This is a collection of exercises that illustrates some fundamental aspects of Mathematical Finance, in particular the valuation of derivatives. It is aimed at students of master's degree courses, but can also be successfully used in first level degree courses, by students who have adequate mathematical training (degree courses in mathematics, engineering). The resolution of the exercises is addressed with the use of methods of both Probability Theory (stochastic processes) and Mathematical Analysis (Partial Derivative Equations).
Equazioni a derivate parzial I : Complementi ed esercizi
La presente raccolta di problemi ed esercizi nasce dall'esperienza maturata durante il corso di Equazioni a Derivate Parziali (EDP), tenuto nell'ambito delle lauree di primo e secondo livello presso il Politecnico di Milano. Il volume è diviso in due parti; nei primi quattro capitoli l'obiettivo è l'uso di tecniche classiche, come la separazione delle variabili, il principio di massimo o le trasformate di Laplace e Fourier, per risolvere problemi di diffusione, trasporto e vibrazione. Il quinto capitolo invita a familiarizzare con i risultati di base negli spazi di Hilbert, nella teoria delle distribuzioni (o funzioni generalizzate) di Schwartz e in quella degli spazi di Sobolev più comuni. Il sesto ed ultimo capitolo riguarda la formulazione variazionale o debole dei più importanti problemi iniziali e/o al bordo per equazioni ellittiche e di evoluzione. L'introduzione ad ogni capitolo contiene una sintesi degli strumenti teorici più utilizzati.
Difficoltà in matematica : Osservare, interpretare, intervenire = Difficulty in mathematics : Observe, interpret, intervene
In a school context, difficulties in mathematics are an important phenomenon both for its diffusion and for the consequences it has at various levels: from the personal distress experienced by many students, to the negative attitude that large sections of the population build towards our discipline, up to the drop in enrollment in scientific degree courses. Faced with these difficulties, which often manifest themselves in behaviors such as giving up trying or responding at random, the didactic action aimed at recovery is generally a local action, which arises from the identification of errors and then intervenes on knowledge deemed necessary to respond correctly. But this type of intervention generally proves to be unsuccessful, and the teacher - together with the pupil - develops a sense of helplessness and frustration.
Matematica si parte! : Nozioni di base ed esercizi per il primo anno di Ingegneria = Mathematics, let's go! : Basics and exercises for the first year of Engineering
This manual has been created to allow future engineering students to successfully face their studies. Some basic concepts in mathematics are presented, generally already learned before entering the University. It has been found that not all students have a complete mastery of this set of fundamental notions: therefore this manual provides useful support, in the form of both exercises and theoretical notions. The future student will be able to choose the chapters that interest him most, in order to verify his ability to solve problems such as "Review problems", using his own reasoning skills and knowledge.
Matematica generale con il calcolatore
By introducing mathematical objects, it teaches students how to use a computer to perform numerical and symbolic calculations, define a function and calculate its values, plot and explore graphs, and execute simple algorithms. The course is rich in examples, applications, and models, drawn from economics, physics, biology, statistics, and mathematics itself. The analysis of these models constitutes, in a certain sense, the true purpose of the mathematical theory covered. Automatic calculation tools (mathematics software, spreadsheets) are used extensively to explore and illustrate concepts and properties. Mathcad® software, in particular, was used, both as a calculation tool and as a simple yet powerful programming language. Considerable space is devoted to approximation, emphasizing the distinction between numerical and symbolic calculation; to algorithms as a synthesis of the syntactic and semantic aspects of mathematical objects; and to computer simulation, interpreted as a "physical" experiment and a source of conjecture. The ability to use a calculator marks a sort of "democratization" of mathematics: even complex results, which have always required a broad background of knowledge and laborious calculations, are now quickly accessible to anyone who understands the meaning of mathematical objects and knows how to use the syntax.
Matematica e cultura in Europa
Non è vero che la matematica susciti sempre poco interesse. Questa almeno è l'impressione che si ricava quando lo spunto per parlarne viene non solo dalla scienza e dalla tecnologia, ma anche dall'arte, dalla letteratura, dal cinema e dal teatro. Ce lo ha insegnato Michele Emmer con i suoi convegni Matematica e Cultura e lo abbiamo sperimentato a Bologna con le iniziative del 2000 per l'Anno Mondiale della Matematica e per Bologna Città Europea della Cultura. D’altra parte, negli ultimi anni abbiamo finalmente visto sullo schermo come protagonisti di film di successo dei matematici, non rappresentati come individui strani, ma come professionisti che svolgono il proprio lavoro, non necessariamente di insegnanti. Anche alcune opere teatrali di risonanza internazionale hanno parlato di matematici e questo ci ha spinto a organizzare per la prima volta in Italia, a Bologna, la rassegna Matematica e Teatro, che ha dato occasione non solo di assistere a spettacoli molto piacevoli, ma anche di parlare dei rapporti tra scienza, matematica e potere al tempo di Napoleone, di numeri primi, di teoria di Galois.
