Computerized systems are becoming smaller, ubiquitous and more interconnected. Netbooks to smart highways all are expected to be more autonomous and connected to each-other. Such interconnected systems have to manage information and regulate actions on their own, with minimal external guidance. A sensor network is a typical example. With scarce resources and no ready infrastructure, it forms a ...

Since changes in trade openness are typically confounded with other factors, it has been difficult to identify the labor market consequences of increased international trade. The advent of the United States Interstate Highway System provides a unique policy experiment, which I use to identify the effect of reducing trade barriers on the relative demand for skilled labor. The Interstate Highway ...

SmartAHS is a software framework for the uniform speciication, simulation, and objective evaluation of Intelligent Vehicle Highway System (IVHS) alternatives. This paper illustrates the use of the object-oriented paradigm in its design, implementation and use. Objective comparison of proposed highway automation alternatives is achieved, when all control architectures are speciied in SmartAHS. T...

W ith the advent of the automobile as a mode of transportation late in the nineteenth century, a new phenomenon, the motor vehicle acci­ dent, appeared on the American scene. While the motor vehicle was in its early stages of development, the problem was not serious. How­ ever, as the volume of cars on the highways increased, the number of accidents increased also; the problem began to assume g...

In this paper we analyze in detail the energy consumption characteristics of the Wireless HART protocol when operated with a popular transceiver, the ChipCon CC2420. We analyze how much various factors contribute to the overall energy consumption over a longer period of 12 h. These factors include the amount of management traffic and the power levels required for various transceiver activities ...

The use of reclaimed asphalt pavement (RA) in new asphalt pavements can provide important economical savings, while reducing the negative environmental impact. The European research project PARAMIX aims to improve the techniques for hot mix recycling in plant and cold mix in situ recycling, so as to increase the amount of reclaimed asphalt and develop competitive road pavement rehabilitation te...

A controversial recreation activity is off-highway vehicle use. Off-highway vehicle use is controversial because it is incompatible with most other activities and is extremely hard on natural eco-systems. This study estimates utility theoretic incomplete demand systems for four off-highway vehicle sites. Since two sets of restrictions are equally consistent with utility theory both are imposed ...

In recent years, mixed or/and augmented reality,which aims to integrate virtual space with real space have be received a significant amount of attention in research and development. In particular, tangible interface is one of the interesting research growth areas. The hypothesis of this research project is that the introduction of a tangible interface should assist designers and planners to rec...
