Abstract Given the rapid increase in the use of operational mesoscale models to satisfy different specialized needs, it is important for the community to share ideas and solutions for meeting the many associated challenges that encompass science, technology, education, and training. As a contribution toward this objective, this paper begins a series that reports on the characteristics and performance of an operational mesogamma-scale weather analysis and forecasting system that has been developed for use by the U.S. Army Test and Evaluation Command. During the more than five years that this four-dimensional weather system has been in use at seven U.S. Army test ranges, valuable experience has been gained about the production and effective use of high-resolution model products for satisfying a variety of needs. This paper serves as a foundation for the rest of the papers in the series by describing the operational requirements for the system, the data assimilation and forecasting system characteristics, and the forecaster training that is required for the finescale products to be used effectively.

This paper concerns the local and remote use of an Integrated Circuits (IC) Automated Test Equipment (ATE) for both educational and engineering purposes. This experience was initiated in 1998 in the context of a French network (CNFM) in order to provide a distant control to industrial equipment for academic and industrial people. The actual shared resource is a Verigy V93K System on Chip (SoC) tester platform. The cost of such an equipment is close to 1Mâ?¬, without taking into account the maintenance and attached human resources expenses to make it work properly daily. Although the sharing of this equipment seems to be obvious for education, the French experience is quite a unique example in the world. Here, practical information regarding IC testing and network setup for remote access are detailed, together with the associated training program.

ABSTRACT A new integrated testing system for the validation of stochastic vehicle-snow interaction models is presented in this paper. The testing system consists of an instrumented test vehicle, vehicle-mounted laser profilometer and a snow micropenetrometer. The test vehicle is equipped on each tire with a set of 6-axis wheel transducers, and a GPS-based data logger tracks vehicle motion. Data is also simultaneously acquired from the sensors from the test vehicle’s Electronic Stability Program. The test vehicle provides measurements that include three forces and moments at each wheel center, vehicle body slip angle, speed, acceleration, yaw rate, roll, and pitch. The profilometer has a 3-D scanning laser and an Inertial Measurement Unit to compensate for vehicle motion. Depth of snow cover, profile of snow surface and wheel sinkage can be obtained from the profilometer. The snow micropenetrometer measures the strength of the snow cover before and after vehicle traversal. Preliminary results, including traction, drawbar pull, vehicle states, snow profiles and snow material properties from recent field tests on natural snow cover are presented, demonstrating the capability and potential of the testing system.

Reviews the historical background of the purchase and sketches the main developments during the next century, viz: establishment of the boundaries, exploitation of minerals and fisheries, changes induced by World War II, and statehood.
