Since the marginal revolution of the 1870s, the economic theory of decision-making has been based on the notion of utility. Utility, however, is not measurable. This book reconstructs economists' struggles with issues related to utility measurement from the 1870s to the beginning of behavioral economics in the mid-1980s.

Deals with various important aspects, both theoretical and experimental, of quantum computation and information, including quantum data compression, accessible information, entanglement concentration, limits to quantum computation due to decoherence, quantum error-correction, and the experimental implementations of quantum information protocols.

May be used as a textbook for a one semester introductory course, both for upper level undergraduate students and for graduate students. It is also useful as general education for readers who want the fundamental principles and who have the basic background acquired from their course in physics, mathematics or computers.

This book focuses on a class of uncertain systems that are called imperfect, and shows how much systems can regularly work if an appropriate control strategy is adopted.

Raccattai il diploma di conservatorio, la chitarra con la custodia rigida, il sacco da marinaio Napapijiri e me ne andai chiudendo la porta in un giorno qualsiasi, senza strappi, senza drammi, con buona pace di tutti ma col segreto rancore di non aver neanche detto 'ciao', come un figlio perso in guerra senza mai essere stato un eroe. Fabian vive una vita svagata suonando nei locali notturni di Perugia e Bologna, ma quando l'ambiente spietato della discografia cancella l'uscita del suo primo disco volta le spalle al mondo, rifugiandosi a Torre a Mare per cominciare un'altra vita. Tra le amicizie di una nuova, variopinta umanità, Fabian conosce Alberto e Cristiana, affascinanti proprietari del vecchio yacht Corinna, e con loro intraprende un avventuroso viaggio verso Istanbul che inciderà in maniera profondissima sulla sua esistenza incompiuta.

This book aims to present a pedagogical and self-consistent treatment of the canonical approach to Quantum Gravity, starting from its original formulation to the most recent developments in the field.We start with an innovative and enlightening introduction to the formalism and concepts on which General Relativity has been built, giving all the information necessary in the later analysis. A brief sketch of the Standard Cosmological Model describing the Universe evolution is also given alongside the analysis of the inflationary mechanism. After deepening the fundamental properties of constrained dynamic systems, the Lagrangian approach to the Einsteinian Theory is presented in some detail, underlining the parallelism with non-Abelian gauge theories. Then, the basic concepts of the canonical approach to Quantum Mechanics are provided, focusing on all those formulations which are relevant for the Canonical Quantum Gravity problem. The Hamiltonian formulation of General Relativity and its constrained structure is then analyzed by comparing different formulations. The resulting quantum dynamics, described by the Wheeler-DeWitt equation, is fully discussed in order to outline its merits and limits. Afterwards, the reformulation of Canonical Quantum Gravity in terms of the Ashtekar-Barbero-Immirzi variables is faced by a detailed discussion of the resulting Loop Quantum Gravity Theory. Finally, we provide a consistent picture of canonical Quantum Cosmology by facing the main features of the Wheeler-DeWitt equation for the homogeneous Bianchi models and then by a detailed treatment of Loop Quantum Cosmology, including very recent developments.

This is a book on path integrals which provides a quick and swift description of the topic. It contains original material that never before has appeared in a book. The new topics include the path integrals for the Wigner functions and for Classical Mechanics.

It is well known that FOS can be applied in control applications and systems modeling, and their effectiveness has been proven in many theoretical works and simulation routines. This book aims to propose implementations and applications of Fractional Order Systems (FOS).
