A recent research report released by the U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) has stated that almost 175,000 pedestrians died on U.S roadways between 1975 and 2001. It was also noted in the report that 12% of all deaths related to motor vehicle crashes in the country are pedestrian fatalities. Most of the safety technology to date in vehicles has been applied to protect the occupants in the vehicle. What can vehicle manufacturers do to reduce pedestrian fatalities?

Optical microscopy is one of the most valuable, but under utilized, tools for analyzing fiber reinforced polymer matrix composites. This hands-on instructional book covers a wide range of topics including sample preparation, illumination and contrast techniques, methods and reagents, and applications. Studies are presented that provide insight into processing effects, toughening approaches, damage mechanisms, and environmental effects on the microstructure of composite materials. In addition, the power of optical microscopy to study the microstructure of these heterogeneous, anisotropic materials is illustrated with more than 180 full color images.

The amount of load that can be borne by the different components of the lumbar region is fairly well understood, as are resulting injuries from overloading. Less severe lumbar injuries involve a wide range of factors, including: heredity, obesity, age, occupation, sports, cardiovascular risk factors, and depression. Some of the most painful conditions that require high levels of care involve lumbar spine fracture or soft tissue injury from falls, contact sports, vehicle collisions, aircraft ejection, and underbody blasts from roadway explosions (military injuries). Each of these injury scenarios elicits a different kinematic response of the spine as a result of load direction, magnitude, and duration. Updated from a popular earlier volume, this new compendium includes landmark papers from 1994 through 2013 that focus exclusively on lumbar injuries.

Illumination is a crucial element in many applications, matching the luminance of the scene with the operational range of a camera. When luminance cannot be adequately controlled, a high dynamic range (HDR) imaging system may be necessary. These systems are being increasingly used in automotive on-board systems, road traffic monitoring, and other industrial, security, and military applications. High Dynamic Range Imaging: Sensors and Architectures provides readers with an intermediate discussion of HDR image sensors and techniques for industrial and non-industrial applications. It describes various sensor and pixel architectures capable of achieving HDR imaging, as well as software approaches to make high dynamic range images out of lower dynamic range sensors or image sets. Some methods for automatic control of exposure and dynamic range of image sensors are also introduced.

Experimental and Simulation Tools for Thin-Film Solar Cells describes the methods used for the optical characterization and design of thin-film solar cells. A description of the cells under study (CdTe, CIGS, CZTS, Perovskite, and organic) is given, followed by coupling experimental and simulation studies in order to improve solar cell performances. A detailed discussion on specific optical tools (ellipsometry, photoluminescence and photoreflectance) is included, and a link between materials and measurements is made by studying the relevant physical principles. Finally, a numerical model is provided that can be used to design the structure of a thin-film solar cell.

The last ten years have seen explosive growth in the technology available to the collision analyst, changing the way reconstruction is practiced in fundamental ways. The greatest technological advances for the crash reconstruction community have come in the realms of photogrammetry and digital media analysis. The widespread use of scanning technology has facilitated the implementation of powerful new tools to digitize forensic data, create 3D models and visualize and analyze crash vehicles and environments. The introduction of unmanned aerial systems and standardization of crash data recorders to the crash reconstruction community have enhanced the ability of a crash analyst to visualize and model the components of a crash reconstruction. Because of the technological changes occurring in the industry, many SAE papers have been written to address the validation and use of new tools for collision reconstruction.

This electronic atlas provides an in-depth understanding of the metallurgy and fracture behavior of aluminum-silicon casting alloys, which are used in a wide variety of automotive, aerospace, and consumer product applications. The atlas includes over 300 high-definition microfractographs of fracture profiles and fracture surfaces, accompanied with detailed descriptions and analysis of the fracture features and their significance in the selection, processing, properties, and performance of the alloy. The microfractographs are described and classified according to criteria described in detail in the introductory chapters in the book. The factors determining the fracture mechanism in these alloys, on the basis of their physical and mechanical properties and fracture mechanics, are described and analyzed.
