Based on the research of the CAN/LIN bus communication protocol,an automobile lamps diagnostic system based on the CAN/LIN bus is designed.After the completion of the software and hardware designs of CAN nodes,LIN nodes and CAN/LIN nodes,the faults of automobile lamps can be successfully diagnosed.LIN node collects light switches and the gateway controls the car light's status via detecting the data frame on the LIN bus.The design and complementation of CAN node,LIN node and CAN/LIN gateway was finished,which made it possible to detect failures in vehicle.

Particle emissions of a diesel car fueled with coal to liquids (CTL) on road were tested.The particle number and size distribution were mainly studied.Three typical roads were adopted in this test, including urban arterial roads, secondary roads and freeways.The results show that transient particle number of the car has a corresponding relationship with the vehicle speed.With the speed increasing, the number of both nucleation mode particles and accumulation mode particles increase continuously.With the CTL blend ratio increasing, the number of nucleation mode particles and accumulation mode particles decreases, especially accumulation mode particles whose size are more than 100nm diameter.With the CTL blend ratio increasing, the particle numbers in the three typical roads show downward trends, especially on freeways.It shows that the CTL fuel can distinctly reduce the exhaust particle number of diesel cars on road.

This paper presents an Extension theory-based approach to product design,the basic idea is to use combined qualitative and quantitative modeling in Extenics to describe the user's possible product using process as well as the corresponding internal structural,assembly and motion relationships of product, then mark the contradictory problems via the correlation between the magnitudes and characteristics of various elements, and then obtain the design scheme meeting the requirements by extension transformation method.

On February 24, 2012, NHTSA released a proposed set of Driver Distraction Guidelines covering original equipment in-vehicle device secondary tasks (where secondary tasks are defined as communications, entertainment, information gathering, and navigation tasks not required to drive) performed by the driver through visual-manual means (meaning the driver looking at a device, manipulating a device-related control with the drivers hand, and watching for visual feedback). These Guidelines will be used to identify secondary tasks that interfere with a driver's ability to safely control a vehicle (National Highway Traffic Safety Administration (NHTSA), 2012). The NHTSA Guidelines specify multiple test methods with acceptance criteria. While including a total of seven test protocols in its Notice of Proposed Federal Guidelines (NHTSA, 2012), NHTSA indicates that it prefers the following two test protocols and their associated acceptance criteria: Option EGDS: Eye Glance Testing Using a Driving Simulator, and Option OCC: Occlusion Testing. Following an approach set forth by the Alliance of Automobile Manufacturers (Alliance) and the growing body of research indicating that eye glance behavior is a prominent indicator of driver distraction, these preferred test protocols focus on eye glance behavior as a method for determining which visual or visual-manual secondary tasks are not acceptable for performance by a driver while operating a vehicle.

In this study,a 14×6JJ a-alloy automobile wheel was used as the object,the fatigue strength and lifetime of the wheel suffered from varying amplitude load were predicted with a cumulative danage theory (the modified Miner theorem),which was considered to be accurate and secure,based on the analysis of load spectrum.The predicted lifetime was verified using a reliability theory.The results showed that,the modified Miner theorem was reliable in the prediction of the lifetime of an automobile a-alloy wheel.

Anion exchange membranes (AEMs) are being developed for potential use in fuel cell systems which include portable power applications. In a fuel cell, these membranes transport hydroxide ions from the cathode to the anode. If carbon dioxide is present, carbonate and bicarbonate ions can form, displacing the hydroxide ions. Among the challenges this presents, the carbonate and bicarbonate are less mobile than the hydroxide and therefore the ionic conductivity of the membrane suffers. A procedure is outlined to take data from a permeation based water flux experiment and determine diffusion coefficients and the ionic conductivity of the membrane. The water-membrane diffusion coefficients can be measured from a water flux experiment. Using principles from kinetic theory, the water-membrane diffusion coefficient can be converted to an apropriate ion-membrane diffusion coefficient. Finally, an equation derived from the dusty fluid model can be used to calculate the ionic conductivity of the membrane in different counter ion forms. The calculated ionic conductivities have been shown to agree well with reported values for proton and anion exchange membranes.

Traditionally there has been a distinction between Combinatorial Solid Geometry (CSG) modeling systems and Sculptured Surface Design modeling systems. CSG modeling systems largely model parts which are unsculptured and consist of combinations of common shapes like spheres, prisms, ellipsoids, and the like. These shapes are represented as planar half spaces, and algebraic quadratic surfaces. The boolean combination of these surfaces is usually performed by ray-tracing. Sculptured Surface Design concerns itself with modeling the surface of an object, i.e., the boundaries of an object like an aircraft, a ship, or an automobile. The boundaries are represented by using parametric tensor-product surfaces consisting of Bezier curves and Nonuniform Rational B-spline Surfaces (NURBS). There are many times however, when both modeling approaches are needed. In particular it is often desirable to introduce free-form surfaces into the CSG system. Recent advances in ray- tracing free-form surfaces have allowed the integration of free-form objects in CSG systems. This presentation will discuss the development and integration of NURBS into the Ballistics Research Laboratory CSG modeling system.

The Smart Grid is expected to increase the efficiency of the current power grid, to cope with volatile power production based on renewable resources, to reduce the need for fossil-based energy resources, and to guarantee the stability of power supply. To achieve these objectives, today's power grid is enhanced by information and communication technology to increase the information flow and to enable a sophisticated power production and power demand management. However, as the power grid is extended to a network of networks, it does not only become smarter, but also more vulnerable to security threats. This chapter discusses the current status and future developments of the Smart Grid and its challenges. Enhancements in terms of energy efficiency and new energy management approaches are covered as well as novel security challenges in different parts of the Smart Grid architecture. In short, this chapter analyzes some of the most striking risks and threats concerning the new Smart Grid infrastructure and discusses interdependencies between energy efficiency and security in the Smart Grid.
