The aim of this study is to establish the co-operative communication strategies that are used in air traffic control (ATC) conversations. The research deals with the question: what kind of co-operative communication strategies do pilots and controllers employ in a speech situation with a restricted use of vocabulary, which generally does not permit any deviations from standard phraseology? The strategies in ATC speech are then compared to those used by second language learners. Faerch and Kasper's (1983) taxonomy of communication strategies will serve as a basis for this comparison. The author analyses authentic speech samples from various ATC workstations at Zurich Airport and evaluates various aspects of phraseology training of air traffic controllers.
This book attempts to present exact and approximate analytical solution methods and techniques using queueing theory in the complex multimedia traffic systems with procedures of random multiple access schemes. In particular, this book presents how to approximate the system performance of discrete-time multimedia networks, the probability distribution of the interarrival time of internetwork packets at the adjacent network and the higher moments of the transmission departure distribution and delay in wireless multimedia communication environment. In general the modeling of discrete-time multimedia communication systems are more complex than that of continuous-time systems because multiple state changes can occur from one time-unit to the next. This complicates the analysis of the model. This book also discusses numerical results that illustrate the applications of the theory and various properties.
Promptly growing demand for telecommunication services and information interchange has led to the fact that communication became one of the most dynamical branches of an infrastructure of a modern society. The book introduces to the bases of classical MDP theory; problems of a finding optimal САС in models are investigated and various problems of improvement of characteristics of traditional and multimedia wireless communication networks are considered together with both classical and new methods of theory MDP which allow defining optimal strategy of access in teletraffic systems. The book will be useful to specialists in the field of telecommunication systems and also to students and post-graduate students of corresponding specialties.
One of the first books in the timely and important area of heavy traffic analysis of controlled and uncontrolled stochastics networks, by one of the leading authors in the field. The general theory is developed, with possibly state dependent parameters, and specialized to many different cases of practical interest.
