Status of cost, rate, and time-of-transit models for network links

Description: The dollar- and time-cost properties of characteristics of rail and highway shipments on links are investigated. The basic assumption is that shippers will alter their choice of mode or route as changes occur in the perceived characteristics or properties of these routes. It is posited that their choice is based on three properties and characteristics: the cost (price) of the shipment; the time of transit; and the variability of delivery. Calculations were made for all direct costs; this includ… more

Using a Borated Panel to Form a Dual Neutron-Gamma Detector

Description: A borated polyethylene plane placed between a neutron source and a gamma spectrometer is used to form a dual neutron-gamma detection system. The polyethylene thermalizes the source neutrons so that they are captured by {sup 10}B to produce a flux of 478 keV gamma-rays that radiate from the plane. This results in a buildup of count rate in the detector over that from a disk of the same diameter as the detector crystal (same thickness as the panel). Radiation portal systems are a potential applic… more

Algorithmic generation of railroad and highway routes

Description: A minimum-time algorithm can be used to generate realistic highway routes between specific origins and destinations. Minimizing distances on links will not produce realistic railroad routes if links bear any resemblance to physical trackage. There are also multiple routes between two points since each carrier has its own philosophy. This paper outlines a systematic method of preparing information such that a computer algorithm can generate realistic routes for single- or multiple-carrier moveme… more
