New Coatings For Bridges (Over-Coat Systems), Sudhir Palle, Theodore Hopwood Ii, Bobby W. Meade

Kentucky Transportation Center Research Report

KYTC sought to identify new coatings technologies consistent with overcoating that offer enhancements in terms of ease of application and performance. KYTC contacted paint manufacturers to obtain sample coating systems for characterization by the KYTC Division of Materials and accelerated performance testing by Kentucky Transportation Center (KTC). A total of 14 coating systems from five manufacturers underwent performance testing according to ASTM D5894.


Safety Stock Estimation Of Unit Load Devices For International Airline Operations, Hua-An Lu, Chien-Yi Chen Aug 2012

Safety Stock Estimation Of Unit Load Devices For International Airline Operations, Hua-An Lu, Chien-Yi Chen

Journal of Marine Science and Technology

Unit load devices (ULDs) are used to load air cargo and passengers’ checked baggage for wide-bodied aircraft operations. Since ULDs are reusable at the destination, airlines can invest in an appropriate fleet size for their requirements. The estimation of safety stock levels for every operating airport is a premeditated task because airlines must prepare enough devices for the outbound consignments of each flight. The variance of the number of used devices for each arrival and departure flight will influence the stock level of an airport. For scheduled international services, this study proposes an analytic method based on a cyclically time-sequenced …
