The evolution of car radio in the past seven decades is a perfect illustration of the convergence of diverse technical fields: RF electronics, mobile wireless communications, the Internet, personal computers, consumer electronics, and automotive human machine interfaces. The early part of the radio evolution was driven by the need to improve the received audio signal quality while in the past two decades the driver has been to increase the channel capacity and to enhance the degree of personalization. Besides traditional AM/FM programming, today's radios also play a variety of media such as cassette tape, CD, MP3, DVD-A etc. as well as over 100 channels of satellite digital audio programs. Going forward, we believe that the radio will continue to be the entertainment center of the vehicle, and that the consumers are expecting to have access to personalized information anywhere and anytime.

Entertainment is the “killer application” for high value telematics services in vehicles. Entertainment does not require a new, untested consumer business model: consumers have been “paying” for entertainment in vehicles for decades. Examples include purchases of audio cassettes and CDs; listening to radio advertising; and more recently, the rental or purchase and playback of videotape movies in the rear seat. Today, technology advances in digital satellite broadcasting, digital compression, mass data storage, and broadband wireless communications are driving very dynamic business opportunities for entertainment service delivery to vehicles. Obvious examples are XM and Sirius Radio, DVD movies, rear seat video games, and MP3 audio playback from flash memory or hard disc drives. A more advanced example is the direct sale and download of compressed digital audio, video, and game software via wireless links that bypass the conventional bricks and mortar retail business.

Into the DEAP The Distributed Electrical Aerospace Propulsion project looks toward a future optimized integrated propulsion system that will allow cleaner, quieter, and more efficient performance to be incorporated into a radically innovative airframe that will feature enclosed electrically powered fans. Managing the deluge of data The model-based development (MBD) process has been a key enabler of technical advancement in the transportation industry; however, the MBD process leads to the generation of large volumes of data artifacts and work products. To maintain efficiency while continuously improving the quality of products, it is necessary to be able to manage this data in an efficient manner.

Showing how it's done Engineers are using software to better manage product development data, and applying tools to a new class of problems. NASA goes deep The agency's new long-term space exploration program starts with a return to the moon and will ultimately enable future exploration of Mars and other solar system destinations. Farnborough preview In an event that happens just once every two years, bringing the multitudes together, it is important to get as much technology as possible into the open and to find solutions to hard problems. Seats under crash loading The FAA and academia have conducted aircraft seat drop tests to compare and contrast passenger crash protection. A fluid approach Aerospace engineers have started using CFD software earlier and earlier in the design process.

The Dictionary of Metals is the authoritative reference work for terms and definitions of metals and terms relating to metals. It also includes a considerable amount of history starting with the seven metals of antiquity. Each of the metallic elements has a discussion that includes the discoverer and date, the naming of the metal and its meaning, the major applications, the significance of the discovery, and physical properties. Includes a timeline of important events in the history of metals and metallurgy.

This book describes the evolution from piston engines to gas turbines by the engineers who created those engines. Included are hundreds of archival photographs, as well as over a dozen tables listing specifications and applications. The story starts with the founding of the company in the 1920's to provide reliable air-cooled piston engines to the military and to help create coast-to-coast commercial flight service. Pratt & Whitney quickly dominated commercial and military flight in the 1930's - ultimately providing half the horsepower of American engines during WWII. Jack Connors explains how Pratt & Whitney came from behind the competition on developing gas turbines after the war with the debut of the J57, which powered the B-52 in 1952 and later the Air Force Century Series fighters (F-100, F-101, F-102) and the Navy A3D, F4D, and F-8 airplanes.

Managing Complexity is the first book that clearly defines the concept of Complexity, explains how Complexity can be measured and tuned, and describes the seven key features of Complex Systems: 1. Connectivity 2. Autonomy 3. Emergency 4. Non-equilibrium 5. Non-linearity 6. Self-organisation 7. Co-evolution The thesis of the book is that complexity of the environment in which we work and live offers new opportunities and that the best strategy for surviving and prospering under conditions of complexity is to develop adaptability to perpetually changing conditions. An effective method for designing adaptability into business processes using multi-agent technology is presented and illustrated by several extensive examples, including adaptive, real-time scheduling of taxis, see-going tankers, road transport, supply chains, railway trains, production processes and swarms of small space satellites.

The federal government and industry have moved to concurrent acquisition and development processes using integrated process teams (IPTs). These processes are supported by timely, accurate, cross functional access to data within an integrated data environment (IDE) enabled by advances in information technology (IT). Since the advent of acquisition reform in 1994, Data Management (DM) practices have evolved from being directed by a prescriptive set of standards and procedures to use of the guidance in a principles-based standard -- ANSI/EIA 859.

GEIA Handbook 859 provides implementation guidance for ANSI/EIA 859, with discussions of applications of the standard's principles, tools, examples, and case studies. Handbook 859 is organized according to the lifecycle of data management and covers activities from the pre-RFP stage through records disposition.

Many companies have successfully adopted Lean manufacturing as an operational philosophy, creating a universal understanding of value and waste which in turn provides significant advantages in the market. However, few have reached the true goal of driving this mindset throughout the organization. For many reasons, this has proven particularly difficult in environments such as engineering and development due to the iterative nature of design and test, the lack of repetition, and the over-all length of time consumed by the process. However, product development is in fact a process that can be controlled. This paper describes methods used by a group of Curtiss Wright companies to improve the overall execution of the product development cycle by first creating inter-departmental flow, tracking that flow with visual metrics, and improving performance with a variety of Lean techniques.
