Book Synopsis Quantum Communications and Cryptography by : Alexander V. Sergienko
Download or read book Quantum Communications and Cryptography written by Alexander V. Sergienko and published by CRC Press. This book was released on 2018-10-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.

Download or read book The Challenge of Change written by Rebecca Hampl and published by Christian Faith Publishing, Inc.. This book was released on 2022-08-01 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the age of twenty-eight, Marty Ellis is still a bachelor who graduated with a major in journalism and a minor in photojournalism. He enjoys his life with various girlfriends while knocking back drinks in bars, going out to dinner, and rolling in the sheets. Yet inevitably, he grows tired of these surface-level-only feelings, shells out his standard goodbye speech, and moves on. However, using only his body and saying sayonara to his love lifeaEUR(tm)s revolving door is not how he wants to live for the rest of his life. How will he ever know what true love feels like if he doesnaEUR(tm)t ascertain how to actually give it? In what way will he begin to be able to discover the whole package that runs beneath the surface of a woman? Unexpectedly, Marty is blindsided when his best friend invites him to leave New Jersey for a weekend trip. Lauren Morris is a beautiful thirty-two-year-old woman who, after graduating at the age of twenty-one with a masteraEUR(tm)s degree in business, took a huge leap of faith and purchased an old farmhouse in Vermont. After ten years of hard work and sweat equity, she has transformed it into a beautiful inn that has become extremely lucrative. But winter is fast approaching, and she is dreading that feeling of loneliness that is connected to darkened afternoons and long, empty nights. Will a man ever enter her life? One that she could love and perhaps be with until death due them part? After meeting Marty, Lauren begins to consider if this man might be the one she has been waiting for her whole life. But then again, she is older than he is; long distance relationships hardly ever work out; and sudden heartbreaking unforeseen events rock both of their worlds. And if they do fall in love, which one of them will have to make the ultimate sacrifice and give up what theyaEUR(tm)ve worked so hard to achieve in order to be together? With so many changes causing so many challenges, will they get through them together, or will one push the other away?

Available in PDF, EPUB and Kindle. Book excerpt: Suitable for both individual and group learning, Engineering Acoustics focuses on basic concepts and methods to make our environments quieter, both in buildings and in the open air. The author’s tutorial style derives from the conviction that understanding is enhanced when the necessity behind the particular teaching approach is made clear. He also combines mathematical derivations and formulas with extensive explanations and examples to deepen comprehension. Fundamental chapters on the physics and perception of sound precede those on noise reduction (elastic isolation) methods. The last chapter deals with microphones and loudspeakers. Moeser includes major discoveries by Lothar Cremer, including the optimum impedance for mufflers and the coincidence effect behind structural acoustic transmission. The appendix gives a short introduction on the use of complex amplitudes in acoustics.

Book Synopsis The Political Economy of Populism by : Petar Stankov
Download or read book The Political Economy of Populism written by Petar Stankov and published by Routledge. This book was released on 2020-07-21 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Political Economy of Populism explores the interplay between identity, the economy and inequality to explain the dynamics of populist votes since the beginning of the 20th century. The book discusses the political and economic implications of populist governance using data on populist incumbencies and linking it to historical data on the macro economy and democracy. Chapters draw from the most recent political science, economics and other social science literature, as well as historical data, to explain the long-term causes and consequences of populism. Populism emerges and gains traction when political entrepreneurs exploit underlying identity conflicts for political gains. As the distributional consequences of both economic distress and economic growth typically favor the elite over the poor and the lower middle class, economic shocks usually sharpen the underlying identity conflicts between the groups. The book provides evidence of significant differences in the ways fiscal and monetary policies are conducted by incumbent populists in Latin America, Europe and the OECD. The work concludes by suggesting avenues through which a 21st century social consensus can be built, so that our society can avoid repeating the mistakes that led to wars and failed economic experiments in the 20th century. The Political Economy of Populism marks a significant contribution to the study of populism and is suited to students and scholars across the social sciences, including economics, political science and sociology.

Book excerpt: CE MEMOIRE PRESENTE LES RESULTATS THEORIQUES ET EXPERIMENTAUX OBTENUS SUR L'ETUDE DES EFFETS D'UNE BOUCLE DE CONTRE-REACTION OPTOELECTRONIQUE SUR UNE DIODE LASER SOUS INJECTION OPTIQUE. L'INJECTION OPTIQUE PERMET D'AMELIORER LES QUALITES SPECTRALES ET SPATIALES DES LASERS EN TRANSFERANT LA PURETE SPECTRALE DU LASER MAITRE VERS LE LASER ESCLAVE INJECTE. CEPENDANT, A FORTE PUISSANCE D'INJECTION, DES INSTABILITES APPARAISSENT DANS LE FONCTIONNEMENT DU LASER ESCLAVE REDUISANT LA PLAGE DE VERROUILLAGE. DE PLUS, LES LIMITES DE CETTE PLAGE DEPENDENT DE FACON CRUCIALE DU COEFFICIENT DE GAIN NON LINEAIRE ET DU FACTEUR DE COUPLAGE PHASE-AMPLITUDE. AUSSI, LA MESURE DU DOMAINE DE VERROUILLAGE PERMET DE DETERMINER LA VALEUR DE CES PARAMETRES.

UN FEED-BACK NEGATIF STABILISE LE LASER DANS LE DOMAINE INSTABLE. LES NOUVELLES LIMITES DE LA PLAGE DE VERROUILLAGE OBTENUES MONTRENT QUE L'AMORTISSEMENT EST D'AUTANT PLUS EFFICACE QUE LE RETARD DE LA BOUCLE EST FAIBLE. LE FEED-BACK POSITIF PERMET, PAR CONTRE, D'AMPLIFIER ET DE STABILISER EN FREQUENCE LA MODULATION GENEREE PAR L'INJECTION. ON OBTIENT AINSI EXPERIMENTALEMENT UNE SOURCE LASER MODULEE A PLUSIEURS GIGAHERTZ SANS ALIMENTATION EXTERIEURE. L'ACCORDABILITE DE LA FREQUENCE DE MODULATION EST OBTENUE PAR LE CONTROLE DU COURANT DES LASERS
