"Introduction to Antenna Placement and Installation" introduces the characteristics of antennas and their integration on aircraft. The book covers antenna siting and placement, computational antenna modelling on structures, measurement on sub-scale models of the airframe, full-scale ground measurements and in-flight measurements.

The author addresses the different stages in the process of developing an entire antenna layout, as well as covering individual retrofits on existing platforms. She explains the physics of antenna placement qualitatively, thus obviating the requirement to understand complex mathematical equations.

Provides a reference book & guide written primarily for Antenna and Integration Engineers but which will also be of interest to Systems Engineers and Project Managers Includes chapters on aircraft systems using antennas, restrictions & trade-offs, frequency & spatial coverage considerations, effect of other antennas & obstacles, RF interoperability issues associated with radiated emissions, computer modelling software, scaled model & full-scale measurements, comparison between measurements & modelling, as well as ground tests and in-flight measurements Describes techniques that can be applied equally to antennas on other structures such as land or sea vehicles and spacecraft Illustrated throughout with figures & diagrams as well as a full colour plates

As with the introduction of x -ray computed tomography, much of the initial development of magnetic resonance applications tended to focus on the central nervous system. The development of magnetic resonance imaging applications to other organ systems such as the chest, abdomen, pelvis and extremities has lagged somewhat behind, awaiting technical improvements, and a broader user base. The past two years have seen a marked increase in imaging applications throughout the body, most notably the musculoskeletal system. It is in this regard, that MRI of the Body is a welcome arrival as a text which describes both basic principles of magnetic resonance ima ging and surveys the current status of magnetic resonance imaging applications throughout the body. The volume is concise, focused, clinically oriented, and abun dantly illustrated. In each organ system, the appropriate technical approach is discussed, the normal anatomic features are reviewed, and the range of pathologic appearances which may be encountered are described. The authors of the chapters provide a balanced overview of MR applications and describe both present limitations and future potential of magnetic resonance imaging applications in the organ system described.

This Festschrift brings together 28 invited papers surveying the state of the art in language testing. The papers, by key figures in the field of language testing, cover issues ranging from test construct definition to the design and applications of language tests, including their importance as a means of exploring larger issues in language teaching, language learning and language policy.The volume locates work in language assessment in a context of social, political and ethical issues at a time when testing is increasingly expected to be publicly accountable. It is thus particularly appropriate as a tribute to Alan Davies, whose work in this field since the 1960s has been marked by its conceptual strength and social responsiveness,seeking constantly to clarify and challengecurrent practice and new trends.

This volume focuses on the social aspects of language testing, including assessment of socially situated language use and societal consequences of language tests. The authors argue that traditional approaches to ensuring social fairness in tests go some way to addressing social concerns, but a broader perspective is necessary to examine the functions of tests on a societal scale.

Considers these issues in relation to language assessment in oral proficiency interviews, and to the assessment of second language pragmatics.Argues that traditional approaches to ensuring social fairness in tests go some way to addressing social concerns, but a broader perspective is necessary if we are to fully understand the social dimension of language assessment.
