    Our global temperature's rise is caused by our atmosphere's ever-increasing content of carbon-dioxide, most of which comes from the exhaust of transportation vehicles. This has resulted in a worldwide search for alternatives to the high-powered gasoline fueled automobiles in wide use today. Replacing gasoline-powered cars with electric and hybrid-electric vehicles has become the most popular tool for reducing carbon-dioxide emissions into our atmosphere. Evaluation of electric alternatives to gasoline-engine propulsion of cars covers such topics as the efficiency, weight, and lifetime of fuel cells, and increasing the charge/discharge life of the new lightweight lithium and nickel metal-hydride batteries. A summary of the work currently being carried out on battery and hybrid vehicles is included here View full abstract»

    The development of virtual instruments (VIs) is bringing a great revolution to the fields of automated testing and measurement. It is accelerating the integration of measurement systems and is promoting instrument standardization, modularization and generalization. A graphical programming platform for automated testing is one of the most important applications of VI technology, and it provides users with an intuitive and friendly programming environment. The visual component library (VCL) is the key part of such graphical programming platforms. The research reported in this paper makes full use of the advantages of the object-oriented methodology to develop the visual VI components for a graphical programming platform. By setting up two base classes for all the VI components, various VIs can be efficiently developed View full abstract»

  • Comparison of C- and X-band InSAR data for 3D characterization of an urban area

    In this paper we offer an overview of a number of algorithms suitable for 3D characterization of an urban environment from interferometric SAR data. By means of these algorithms we compare fine resolution C- and X-band SAR measurements over the same area to understand what useful information can be derived from these measurements. In addition we examine the similarities and differences of these data sets that are acquired with different frequency bands, bandwidths, and radar look direction. These data sets are recorded over Los Angeles, California, by the C-band NASA/JPL AIRSAR system, and by X-band Intermap Star-3i system. We analyze the original range measurements as reconstructed after the phase unwrapping procedure, the bald earth topography that we were able to retrieve, and the 3D shapes of some of the buildings in the UCLA area. Our results show that both data sets provide useful information of urban 3D characteristics. The better ground resolution of the X-band system results in better building shape extraction. Lower resolution of the C-band data, surprisingly, was not a limiting factor for extraction of large building structures. We demonstrate that it is possible to extract the terrain elevation model (bald earth topography), and the heights of large building structures by means of our algorithms View full abstract»

  • Design and applications of airborne radars in the VHF/UHF band

    The simultaneous need for ground penetration and high resolution dictates the use of frequencies less than 500 MHz for imaging ground penetrating radar (GPR) designs. It is possible to build such systems with good performance and yet not interfere with ground installations operating in the same bands. The total number of airborne GPR systems needed to saturate the market is small, (possibly less than ten), and so the buildup of noise in this spectral region occupied by these radars will be negligible. This is fortunate, since there is a clear need for such radars in such areas as humanitarian demining and unexploded ordnance (UXO) mapping. Some formal set of guidelines is needed beyond that given in Part 15 of the FCC regulations, which both recognizes the need for airborne UWB radar operations, and still protects licensed users in the band View full abstract»

  • Robotic technology integration for army ground vehicles

    This paper discusses the US Army Tank Automotive Research, Development and Engineering Center's (TARDEC's) four (4) axis strategy for integration of robotics into the legacy, interim, and objective forces. At the cornerstone of this strategy is the R&D effort concentrating on autonomous perception and navigation, intelligent tactical behavior, command and control, and man-robot interface entailed in the Demo III and Robotic Follower programs. Smart Manned Systems focuses on a systems engineering approach for robotic solutions into the interim force (Vetronics Technology Testbed and Crew Integration & Automation Testbed). In the near-term, application of robotics to the legacy force will be achieved through adapting commercial automation technologies, which address military requirements. Finally, Intelligent Mobility will investigate improving intrinsic platform mobility to lessen the burden on robotic sensing performance. The ultimate goal of this strategy is to advance the robotics technology state-of-the-art to achieve off-road full autonomous operations for military systems in support of the objective force View full abstract»

  • Achieving security in integrated circuit card applications reality or desire?

    It has always been claimed that smart cards provide a really high level of security, considering them as a tamper-proof device, with the possibility to auto-block some or all of the services it provides. Unfortunately, nowadays some hackers appear to have demonstrated the lack of security involved in some applications where Integrated Circuit Cards (ICC) have been used. This has led to the opinion that smart cards are not secure enough, and their security is only in the minds of the commercial companies involved with the technology. In this paper, the author explains the reasons why this hacking has succeeded. For example, sometimes memory cards have been used instead of smart cards, or very old smart cards have been issued and not renewed, or the development team involved has not used basic security techniques, such as diversified keys. The author also gives clues to achieve a high level of security depending on the final application, and the environment in which it is going to be used View full abstract»
