    Description / Table of Contents: Zusammenfassung Es wurden Titan(IV)-dithiocarbamat-Komplexe vom TypCpTi(S2CNHR)Cl2 undCpTi(S2CNHR)2Cl mitR=C8H5N2S, C9H5N2SCl2 und C9H7N2S mittels der Reaktion von Monocyclopentadienyltitan(IV)trichlorid mit dem Kaliumsalz der entsprechenden Dithiocarbaminsäure in wasserfreiem Dichlormethan dargestellt. Leitfähigkeitsmessungen und IR-Untersuchungen zeigen, daß diese Komplexe Nichtelektrolyte sind, bei denen alle Dithiocarbamat-Liganden zweizähnig sind. Demnach können 5-, bzw. 6-koordinierte Strukturen für die Komplexe des TypsCpTi(S2CNHR)Cl2, bzw.CpTi(S2CNHR)2Cl angenommen werden. Die1H-NMR Spektren zeigen eine rasche Rotation des Cyclopentadienylrings um die Metall-Ring Achse an.
    Notes: Abstract Titanium(IV) dithiocarbamato complexes of the typesCpTi(S2CNHR)Cl2 andCpTi(S2CNHR)2Cl, whereR=C8H5N2S, C9H5N2SCl2 and C9H7N2S, have been prepared by the reaction of monocyclopentadienyl titanium(IV) trichloride with the potassium salt of the appropriate dithiocarbamic acid in anhydrous dichloromethane. Conductance and infrared studies indicate that these complexes are non-electrolytes in which all dithiocarbamate ligands are bidentate. Therefore, 5 and 6 coordinate structures can be assigned toCpTi(S2CNHR)Cl2 andCpTi(S2CNHR)2Cl complexes, respectively.1H-NMR spectra indicate that there is rapid rotation of the cyclopentadienyl ring about the metal ring axis.

    Notes: Summary An exact axisymmetric piezothermoelastic solution is presented for a simply-supported hybrid cylindrical shell made of cross-ply composite laminate and piezoelectric layers. Numerical results for hybrid shells are presented for sinusoidal and central band thermal and electrical loads. The effect of the loading, the radius-to-thickness ratio, the span-to-radius ratio and the number of layers of the substrate on the response is investigated. The interface between the substrate and the actuated piezoelectric layer has been found to be subjected to high shear stress. It has been shown that the maximum values of the deflection and the stresses, due to thermal load, can be appreciably reduced by appropriate application of actuation potential.

    An exact axisymmetric solution for a simply supported piezoelectric cylindrical shell (1997)
    Springer

    ISSN: 1432-0681
    Keywords: Key words piezothermoelasticity ; cylindrical shell ; piezoelectric ; axisymmetry.

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Summary Three-dimensional axisymmetric solution is presented for a simply supported piezoelectric cylindrical shell. The variables are expanded in Fourier series to satisfy the boundary conditions at the ends. The solution of the governing differential equations with variable coefficients is constructed as a product of an exponential function and a power series. The coefficients of terms of all degrees in the governing equations are set to zero, yielding a characteristic equation for the exponent and recursive relations for the coefficients of the power series. Results are presented illustrating the effect of thickness parameter of the shell. An inverse problem of inferring the applied temperature from the measured potential difference has been solved.

    A class of two-dimensional cellular automata and their applications in random pattern testing (1994)
    Springer
    Journal of electronic testing 5 (1994), S. 67-82 
    Details
    ISSN: 1573-0727
    Keywords: Built-in self-test ; cellular automata (CA) ; pseudo-random patterns ; 2-D CA
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract A basic framework to characterize the behavior of two-dimensional (2-D) cellular automata (CA) has been proposed. The performance of the regular structure of the 2-D CA has been evaluated for pseudo-random pattern generation. The potential increase in the local neighborhood structure for 2-D CA has led to better randomness of the generated patterns as compared to LFSR and 1-D CA. The quality of the random patterns generated with 2-D CA based built-in-self-test (BIST) structure has been evaluated by comparing the fault coverage on several benchmark circuits. Also a method of synthesizing 2-D CAs to generate patterns of specified length has been reported. The patterns generated can serve as a very good source of random two-dimensional sequences and also variable length parallel pattern generation having virtually nil correlation among the bit patterns.
