This book offers, from both a theoretical and a computational perspective, an analysis of macroscopic mathematical models for description of charge transport in electronic devices, in particular in the presence of confining effects, such as in the double gate MOSFET. The models are derived from the semiclassical Boltzmann equation by means of the moment method and are closed by resorting to the maximum entropy principle. In the case of confinement, electrons are treated as waves in the confining direction by solving a one-dimensional Schrödinger equation obtaining subbands, while the longitudinal transport of subband electrons is described semiclassically. Limiting energy-transport and drift-diffusion models are also obtained by using suitable scaling procedures. An entire chapter in the book is dedicated to a promising new material like graphene. The models appear to be sound and sufficiently accurate for systematic use in computer-aided design simulators for complex electron devices. The book is addressed to applied mathematicians, physicists, and electronic engineers. It is written for graduate or PhD readers but the opening chapter contains a modicum of semiconductor physics, making it self-consistent and useful also for undergraduate students.
The book is divided into three parts, which contain respectively recent results in the kinetic theory of granular gases, kinetic theory of chemically reacting gases, and numerical methods for kinetic systems. Part I is devoted to theoretical aspects of granular gases. Part II presents recent results on modelling of kinetic systems in which molecules can undergo binary collisions in presence of chemical reactions and/or in presence of quantum effects. Part III contains several contributions related to the construction of suitable numerical methods and simulations for granular gases.
This fourth volume in the comprehensive series “fills a gap in the existing narrative” of WWII’s Mediterranean air war (Journal of Military History). The fourth volume in this momentous series commences with the attacks on the Italian island fortress of Pantellaria, which led to its surrender and occupation achieved almost by air attack alone. The account continues with the ultimately successful, but at times very hard fought, invasions of Sicily and southern Italy as burgeoning Allied air power, now with full US involvement, increasingly dominated the skies overhead. The successive occupations of Sardinia and Corsica are also covered in detail. This is essentially the story of the tactical air forces up to the point when Rome was occupied, just at the same time as the Normandy landings were occurring in northwest France. With regards to the long-range tactical role of the Allied heavy bombers, only the period from May to October is examined, while they remained based in North Africa, with the narrative continuing in a future volume. This volume also delves into the story of “the soldiers’ air force.” Frequently overshadowed by more immediate newsworthy events elsewhere, the soldiers’ struggle was often of an equally Homeric nature. “No future publication on the Mediterranean air war will be credible without use of this series.” —Air Power History
Outstanding selection of tales include the celebrated "Cavalleria Rusticana" (Rustic Chivalry), "Nedda," "L'amante di Gramigna" (Gramigna's Mistress), "Reverie," "Jeli the Herdsman," "Nasty Redhead," and 6 others. Introduction. Notes.
The stories of Giovanni Verga (1840-1922) are wonderful evocations of ordinary Italian life, focusing in particular on his native Sicily. In an original and dynamic prose style, he portrays such eternal human themes as love, honour and adultery with rich and colourful language. The inspiration for Mascagni's opera, 'Cavalleria Rusticana' depicts a young man's triumphal return home from the army, spoilt when he learns that his beloved is engaged to another man. Verga's acute awareness of the hardships and aspirations of peasant life can be seen in stories such as 'Nedda', 'Picturesque Lives' and 'Black Bread', while others such as 'The Reverend' and 'Don Licciu Papa' show the dominance of the church and the law in the Sicilian communities he portrays so vividly.
