    Notes: Abstract Coda wave data from California microearthquakes were studied in order to delineate regional fluctuations of apparent crustal attenuation in the band 1.5 to 24 Hz. Apparent attenuation was estimated using a single back scattering model of coda waves. The coda wave data were restricted to ≤30 s following the origin time; this insures that crustal effects dominate the results as the backscattered shear waves thought to form the coda would not have had time to penetrate much deeper. Results indicate a strong variation in apparent crustal attenuation at high frequencies between the Franciscan and Salinian regions of central California and the Long Valley area of the Sierra Nevada. Although the codaQ measurements coincide at 1.5 Hz (Q c =100), at 24 Hz there is a factor of four difference between the measurements made in Franciscan (Q c =525) and Long Valley (Q c =2100) with the Salinian midway between (Q c =900). These are extremely large variations compared to measures of seismic velocities of comparable resolution, demonstrating the exceptional sensitivity of the high frequency codaQ measurement to regional geology. In addition, the frequency trend of the results is opposite to that seen in a compilation of codaQ measurements made worldwide by other authors which tend to converge at high and diverge at low frequencies, however, the worldwide results generally were obtained without limiting the coda lengths and probably reflect upper mantle rather than crustal properties. Our results match those expected due to scattering in random media represented by Von Karman autocorrelation functions of orders 1/2 to 1/3. The Von Karman medium of order 1/3 corresponding to the Franciscan codaQ measurement contains greater amounts of high wavenumber fluctuations. This indicates relatively large medium fluctuations with wavelengths on the order of 100 m in the highly deformed crust associated with the Franciscan, however, the influence of scattering on the codaQ measurement is currently a matter of controversy.

    On Chinese earthquake history — An attempt to model an incomplete data set by point process analysis (1979)

    Notes: Abstract Since the 1950s, the Academia Sinica in Peking, People's Republic of China, has carried out extensive research on the Chinese earthquake history. With a historical record dating back some 3000 years, a wealth of information on Chinese earthquakes exists. Despite this monumental undertaking by the Academia Sinica, much work is still necessary to correct the existing earthquake data for historical changes in population, customs, modes of communication, and dynasties. In this paper we report on the status of our investigation of Chinese earthquake history and present some preliminary results. By applying point process analysis of earthquakes in ‘Central China’, we found suggestions of (1) lower earthquake activity at intervals of about 175 years and 375 years, and (2) higher earthquake activity at an interval of about 300 years.

    Comparison of techniques that use the single scattering model to compute the quality factorQ from coda waves (1991)
    Springer
    Pure and applied geophysics 135 (1991), S. 77-89

    ISSN: 1420-9136
    Keywords: CodaQ ; attenuation ; scattering ; coda waves ; seismic waves

    Topics: Geosciences , Physics
    Notes: Abstract Using simulated coda waves, the resolution of the single-scattering model to extract codaQ (Q c ) and its power law frequency dependence was tested. The back-scattering model ofAki andChouet (1975) and the single isotropic-scattering model ofSato (1977) were examined. The results indicate that: (1) The inputQ c models are reasonably well approximated by the two methods; (2) almost equalQ c values are recovered when the techniques sample the same coda windows; (3) lowQ c models are well estimated in the frequency domain from the early and late part of the coda; and (4) models with highQ c values are more accurately extracted from late code measurements.

    High precision, low cost mask for deep x-ray lithography (1998)
    Springer
    Microsystem technologies 4 (1998), S. 66-69

    Notes: Abstract  The precision of transferred patterns are highly dependent on the quality of the mask in deep x-ray lithography. Many parameters, such as the critical energy of the synchrotron light, beamline optics and even the microstructure to be exposed should be considered in mask design. In this paper, the design rules and the boundary conditions for deep x-ray mask are discussed in general. The method of making a precision, multilayer mask using UV lithography technique is also described.

    Formation and properties of copper film on Tl-(Pb, Bi)-Sr-Ca-Cu-O superconductor by electrodeposition from aqueous solution (1992)
    Springer
    Journal of materials science 27 (1992), S. 5739-5744

    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract A new process of electrodeposition in saturated cupric sulphate aqueous solution was successfully developed for the formation of copper film on a high-Tc, three Cu-O layered Tl-(Bi, Pb)-Sr-Ca-Cu-O superconductor substrate surface for the first time. Scanning electron microscopy and electron micro-probe analysis were used to investigate the morphology of the substrate surface and the composition of the copper superconductor interface. After the electrodeposition process, no evident changes in the temperature dependence of electrical resistivity were found by four-point probe measurement. The difference of magnetic properties before and after electrodeposition was investigated from magnetization measurements. Almost no degradation of the bulk properties was observed from the susceptibility data. The copper-superconductor contact was confirmed to show Ohmic behaviour by two-pointI–V characterization at liquid nitrogen boiling temperature.

    Notes: Abstract Plastic yielding behaviour of three different cross-link density rubber-modified epoxy resins, at different rubber levels and temperature, were investigated. All the systems studied show decrease in Young's modulus,E, and yield stress, σY, with increasing temperature and rubber content. The deformation process was analysed using both Bowden and Argon theories. Molecular parameters from each. theory were then compared with chemical structures of the epoxy systems.
