Book Synopsis Conception de circuits RF en CMOS SOI pour modules d'antenne reconfigurables by : Dominique Nicolas
Download or read book Conception de circuits RF en CMOS SOI pour modules d'antenne reconfigurables written by Dominique Nicolas and published by . This book was released on 2017 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans le contexte des applications mobiles, les contraintes de conception des chaînes d'émission toujours plus performantes et de taille réduite demandent de compenser la forte sensibilité des caractéristiques des antennes à leur environnement. En particulier, il est nécessaire de maîtriser l'impédance de l'antenne pour optimiser l'efficacité énergétique de la chaîne de transmission. Or, les solutions actuelles se montrent encombrantes. Dans cette thèse, plusieurs pistes basées sur l'implémentation de condensateurs variables ont été étudiées et ont conduit à la réalisation et la caractérisation de nouveaux dispositifs RF intégrés à même de participer à cet effort. Après une présentation du contexte et de l'état de l'art, nous proposons une étude de condensateurs variables basés sur la technique des capacités commutées. L'étude a permis la réalisation de deux condensateurs variables en technologie CMOS SOI 130 nm pour des applications d'adaptation d'impédance et d'antenne agile en fréquence. Un premier démonstrateur d'antenne fente agile en fréquence visant les bandes LTE situées entre 500 MHz et 1 GHz et utilisant ce type de condensateur a ensuite été réalisé puis validé. Un système d'accord permettant de corriger les désadaptations d'antenne a ensuite été étudié et a donné lieu à la réalisation de deux circuits intégrés en technologie CMOS SOI 130 nm. Le premier circuit est un détecteur d'impédance capable de fonctionner sur une gamme de puissance étendue de 0-40 dBm pour une plage de fréquences de 600 MHz-2,4 GHz. Le deuxième circuit intègre une version améliorée du détecteur avec un circuit d'adaptation variable autorisant la réalisation d'un système d'accord d'antenne autonome et compact représentant une avancée importante par rapport à l'état de l'art.

Book Synopsis TOF Range-Imaging Cameras by : Fabio Remondino
Download or read book TOF Range-Imaging Cameras written by Fabio Remondino and published by Springer Science & Business Media. This book was released on 2013-04-09 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today the cost of solid-state two-dimensional imagers has dramatically dropped, introducing low cost systems on the market suitable for a variety of applications, including both industrial and consumer products. However, these systems can capture only a two-dimensional projection (2D), or intensity map, of the scene under observation, losing a variable of paramount importance, i.e., the arrival time of the impinging photons. Time-Of-Flight (TOF) Range-Imaging (TOF) is an emerging sensor technology able to deliver, at the same time, depth and intensity maps of the scene under observation. Featuring different sensor resolutions, RIM cameras serve a wide community with a lot of applications like monitoring, architecture, life sciences, robotics, etc. This book will bring together experts from the sensor and metrology side in order to collect the state-of-art researchers in these fields working with RIM cameras. All the aspects in the acquisition and processing chain will be addressed, from recent updates concerning the photo-detectors, to the analysis of the calibration techniques, giving also a perspective onto new applications domains.

Book Synopsis The Challenge of Change by : Rebecca Hampl
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?

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.
