Although the above technologies have become firmly established in welldefined domains of applications, only few theoretical results have been obtained. Theoretical results are needed not only for explaining the successful results but also for guiding general design methodology for systems. The success of neural networks is explained by the universal approximation property (via Stone-Weierstrass...

22. lappuse - Electron-Channelling Enhanced Microanalysis of Intermetallic Compounds." Substantial increases in positron lifetime were caused in both Ti-49a%Al and Ti-56a%Al alloys by the electron irradiation, demonstrating that there are no structural vacancies on either side of the stoichiometric composition. Osaka University Y. Umakoshi, T. Nakano, and T. Yamane have reported on "Control Lamellae Structure and Plastic Behavior of TiAl Crystals Grown by a Floating Zone Method.
8. lappuse - Lake, he undertook research in clcctrorcflcctance of wide-gap semiconductors and insulators. Beginning in 1973, he participated in the establishment of the Stanford Synchrotron Radiation Laboratory and continued with the application of synchrotron radiation in research in semiconductors and semiconductor surfaces. In 1976 he initiated a research program in liquid-phase epitaxy, followed in 1984 by research in molecular-beam epitaxial growth and characterization of semiconductor materials and hctcrostructurcs.
