Optical fiber has begun replacing copper in avionic networks. So far, however, it has been mainly restricted to non-critical applications (video transmission to the flight deck, IFE?). In order to take advantage of the high-bandwidth, low weight, no EMI properties of optical fibers in all data transmission networks, it will be necessary to improve the testing. One part of the puzzle, which is still missing, is the self-test button: the possibility to check the network and detect potential failures before they occur. The typical testing tool of a technician involved in optical fiber cables is the ?light source ? optical power meter? pair. With this tool, one can measure the insertion loss of the fiber link. A second important parameter, the return loss at each optical connector, is not analysed. In addition, this is only a global measurement, which does not allow the detection of possible weak points.

In Oct. 2011, Nissan announced its new six-year environmental plan, Nissan Green Program 2016 (NGP 2016), that includes initiatives to lead fuel efficiency: 35% fuel economy improvement compared with 2005 on a corporate average for all Nissan vehicles sold in Japan, China, Europe and the United States. To achieve this target, we`re planning to launch products delivering class-leading fuel efficiency such as an all-new FWD hybrid model, Introducing a next-generation continuously variable transmission (CVT). In this session, Nissan`s apploach for fuel erfficiency is presented with internal-conbustion powered technology evolution and hybridization, referring to new FWD hybrid system.

TAUPE is a collaborative research project co-funded by the European Commission in the framework of the Seventh Framework Programme (FP7). It addresses the aeronautic sector and is composed of 17 partners from 6 European countries. The project lasts 3,5 years (September 2008 ? February 2012), is led by Safran Engineering Services (Labinal, SAFRAN Group) and has a budget of 5.5M?. The project aims to simplify the electrical architecture of aircraft and to reduce the length and mass of cabling by introducing PLC (PowerLine Communication) or PoD (Power over Data) technologies inside the aircraft. Both technologies essentially aim to supply power and data over the same cable.

Transmission of light through automotive topcoat and primer layers can lead to degradation of the underlying electrocoat layer and to topcoat delamination. In order to protect against this, it is critical that transmission of both ultraviolet wavelengths and certain visible wavelengths be effectively blocked by the topcoat and primer layers. The clearcoat, basecoat and primer each have their own role and combine to protect against light transmission. The transmittance of these combined layers is typically measured by the Integrating Sphere UV-Visible Spectrophotometer. It would both simplify measurement of the topcoat systems and allow better system modeling if these layers could be measured separately and combined mathematically. We demonstrate here that absorbing and reflecting pigments can be effectively modeled using the Beer-Lambert law while results for scattering pigments are consistent with the Kubelka-Munk theory.

The first commercially available plug-in hybrid electric vehicle (PHEV), the General Motors (GM) Volt, was introduced into the market in mid-December 2010. The Volt uses a series-split powertrain architecture, which provides benefits over the series architecture that typically has been considered for use in electric-range extended vehicles (EREVs). A specialized EREV powertrain, called the Voltec, drives the Volt through its entire range of speed and acceleration with battery power alone and within the limit of battery energy, thereby displacing more fuel with electricity than a PHEV, which characteristically blends electric and engine power together during driving. This paper assesses the benefits and drawbacks of these two different plug-in hybrid electric architectures (series versus series-split) by comparing component sizes, system efficiency, and fuel consumption over urban and highway drive cycles.

Understanding in-use fleet operating behavior is of paramount importance when evaluating the potential of advanced/alternative vehicle technologies. Accurately characterizing real world vehicle operation assists in properly allocating advanced technologies, playing a role in determining initial payback period and return on investment. In addition, this information contributes to the design and deployment of future technologies as the result of increased awareness regarding tractive power requirements associated with typical operating behavior. In this presentation, the concept of vehicle duty cycles and their relation to advanced technologies will be presented and explored. Additionally, current research attempts to characterize school bus operation will be examined, and existing computational analysis and evaluation tools associated with these efforts discussed.

Who are the people who know the most about the buses in your fleet? They are most likely the operators and the servicing technicians. They are also the key people whose knowledge, level of training and attitude can determine the success or failure of new powertrain technologies. Training and recruitment of both need to be held to a higher standard than we have seen in the past. I will argue that even the culture of those involved in fleet operations needs to be changed. The bar for technical competence and product knowledge needs to be raised for operators and technicians. In return managers should find ways to include them as stakeholders, investing them with both additional responsibility and accountability. This will require greater access to training and recognition of achievement. Where are the busses stored and serviced? Most likely in an all-purpose state/county/municipal service facility servicing a variety of equipment.
