Rapid method for sampling metals for materials identification

Nondamaging process similar to electrochemical machining is useful in obtaining metal samples from places inaccessible to conventional sampling methods or where methods would be hazardous or contaminating to specimens. Process applies to industries where metals or metal alloys play a vital role

Optimal Scheduling of Trains on a Single Line Track

This paper describes the development and use of a model designed to optimise train schedules on single line rail corridors. The model has been developed with two major applications in mind, namely: as a decision support tool for train dispatchers to schedule trains in real time in an optimal way; and as a planning tool to evaluate the impact of timetable changes, as well as railroad infrastructure changes. The mathematical programming model described here schedules trains over a single line track. The priority of each train in a conflict depends on an estimate of the remaining crossing and overtaking delay, as well as the current delay. This priority is used in a branch and bound procedure to allow and optimal solution to reasonable size train scheduling problems to be determined efficiently. The use of the model in an application to a 'real life' problem is discussed. The impacts of changing demand by increasing the number of trains, and reducing the number of sidings for a 150 kilometre section of single line track are discussed. It is concluded that the model is able to produce useful results in terms of optimal schedules in a reasonable time for the test applications shown here

Allemande Left and Do-si-do: Missouri Folk Arts Turns Corners With Rural Schools

The Missouri Folk Arts Program (MFAP) has produced educational projects for school children for several years, from traveling exhibitions to school performances. The most long-lasting project is “Tuesdays at the Capitol.” Since 1988, MFAP has partnered with the Department of Natural Resources' Missouri State Museum. Master and apprentice artists who participate in the Traditional Arts Apprenticeship Program (TAAP) perform and demonstrate at venues in and around the Capitol. In early May, emeritus Professor Howard W. Marshall taught a four-day school residency program about Missouri fiddling at two rural Shelby County R-IV elementary schools
