Sommario/riassunto |
|
Laser space communications is a hot topic among electrical engineers working for the government and in the defense industry, and this groundbreaking resource is the first to offer professionals a thorough, practical treatment of the subject. The book focuses on the feasibility of laser space communications between satellites, satellites and airborne platforms, and satellites and ground based stations to achieve worldwide connectivity. It covers all the critical topics that engineers working in the field need to understand such as weather avoidance, 5th Generation Internet (5-GENIN), and noise. |

Sommario/riassunto |
|
How do people learn nonnative languages? Is there one part or function of our brains solely dedicated to language processing, or do we apply our general information-processing abilities when learning a new language? In this book, an interdisciplinary collaboration of scholars and researchers presents an overview of the latter approach to adult second language acquisition and brings together, for the first time, a comprehensive picture of the latest research on this subject. Clearly organized into four distinct but integrated parts, Mind and Context in Adult Second Language Acquisition first |
