Study of crack initiation phenomena associated with stress corrosion of aluminum alloys
Study of stress corrosion cracks in aluminum alloys reveals that crack initiation is greatly influenced by boundary orientation and directionality of the structure. In all crack susceptible materials, intergranular corrosion and stress corrosion cracking started and progressed in boundaries oriented perpendicularly to the stressing direction

A Panel Test of Purchasing Power Parity Under the Null of Stationarity
Purchasing Power Parity (PPP) is tested using a sample of real exchange rate data for
twelve European countries. Acknowledging that Augmented Dickey Fuller tests have
low power, we apply a Panel test that considers the null of stationarity and corrects for
serial dependence using a non-parametric kernel based method

The specification of cross exchange rate equations used to test Purchasing Power Parity
The Article considers the speciÞcation of models used to test Pur-
chasing Power Parity when applied to cross exchange rates. SpeciÞcally,
conventional dynamic models used to test stationarity of the real exchange
rate are likely to be misspeciÞed, except when the parameters of each ex-
change rate equation are the sam
Communication Platform Payload Definition (CPPD) study. Volume 1: Executive summary
This is Volume 1 (Executive Summary) of the Ford Aerospace & Communications Corporation Final Report for the Communication Platform Payload Definition (CPPD) Study program conducted for NASA Lewis Research Center under contract No. NAS3-24235. This report presents the results of the study effort leading to five potential platform payloads to service CONUS and WARC Region 2 traffic demand as projected to the year 2008. The report addresses establishing the data bases, developing service aggregation scenarios, selecting and developing 5 payload concepts, performing detailed definition of the 5 payloads, costing them, identifying critical technology, and finally comparing the payloads with each other and also with non-aggregated equivalent services
