Algebraic Number Theory and Code Design for Rayleigh Fading Channels
ISBN: 9781933019079 / Angielski / Miękka / 2004 / 96 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Algebraic number theory is gaining an increasing impact in code design for many different coding applications, such as single antenna fading channels and more recently, MIMO systems. Extended work has been done on single antenna fading channels, and algebraic lattice codes have been proven to be an effective tool. The general framework has been developed in the last ten years and many explicit code constructions based on algebraic number theory are now available. Algebraic Number Theory and Code Design for Rayleigh Fading Channels provides an overview of algebraic lattice code designs for...

Cyclic Division Algebras: A Tool for Space-Time Coding
ISBN: 9781601980502 / Angielski / Miękka / 2007 / 108 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Cyclic Division Algebras: A Tool for Space-Time Coding provides a tutorial introduction to the algebraic tools involved in the design of codes based on division algebras. The different design criteria involved are illustrated, including the constellation shaping, the information lossless property, the non-vanishing determinant property and the diversity multiplexing tradeoff. Finally complete mathematical background underlying the construction of the Golden code and the other Perfect Space-Time block codes is given.

Harnessing Folksonomies with a Web Crawler
ISBN: 9783639243765 / Angielski / Miękka / 2010 / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Folksonomies play a central role in the
current trend of the World Wide Web design towards collaboration and information sharing. They provide a way to create metainformation in a simple, yet precise manner with little additional costs. The contribution of a large number of users creates a network effect that allow for folksonomies to annotate and categorize a vast amount of resources while including different vocabularies. Various resource sharing and social bookmarking platforms encourage ... Folksonomies play a central role in the

Devoirs Traditionnels Et Devoirs de Projet
ISBN: 9786131533976 / Francuski / Miękka / 2018 / 360 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Notre livre traite de la problA(c)matique suivante: Dans quelle mesure les devoirs traditionnels ou de projet sont-ils une aide ou non pour les A(c)lA]ves et notamment pour les A(c)lA]ves en difficultA(c)?. Pour mener A bien notre recherche, nous avons interrogA(c) des enseignants genevois et effectuA(c) une analyse comparative. Deux objectifs principaux ressortent de la dispense des TTM: la consolidation des contenus et le dA(c)veloppement de l''autonomie. Si le premier objectif n''est finalement qu''A(c)phA(c)mA]re, le second est objectivement observable par les enseignants. Les TTM de...

Coding Techniques for Repairability in Networked Distributed Storage Systems
ISBN: 9781601986764 / Angielski / Miękka / 2013 / 104 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. The most commonly deployed multi-storage device systems are RAID housed in a single computing unit. The idea of distributing data across multiple disks has been naturally extended to multiple storage nodes which are interconnected over a network and are called Networked Distributed Storage Systems (NDSS). The simplest coding techniques based on replication are often used to ensure redundancy in these systems, but given the sheer volume of data that needs to be stored and the overheads of replication, other coding techniques are being developed. Coding Techniques for Repairability in Networked...

Control Para Minimizar Las Perdidas En Convertidores CC-CC
ISBN: 9783659013638 / Hiszpański / Miękka / 2012 / 276 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. En este trabajo se analizan convertidores CC-CC bidireccionales, reductores-elevadores de tension, que tienen por objetivo controlar el flujo de potencia entre dos fuentes de tension, con alto rendimiento. Se realiza un analisis comparativo de diferentes topologias de convertidores CC-CC, concluyendose que el convertidor CC-CC con Puentes Duales Activos (CPDA) es la topologia mas adecuada para cumplir con los objetivos planteados. Se realiza un analisis del funcionamiento de la topologia seleccionada y se determinan las perdidas del convertidor, considerando las originadas en las llaves de...
