We found the linear complexity of quaternary sequences of period over the ring Z_4 . The sequences are based on Whiteman's generalized cyclotomic classes of order four. Also we derived the maximum nontrivial autocorrelation magnitude of the constructed sequences.

In this paper we consider boundary value problems with singularity in equation or solution. To solve these problems, we apply single exponential and double exponential transformations of sinc-Galerkin and Chebyshev cardinal functions. Numerical examples highlight efficiency of Chebyshev cardinal functions…

Gas phase displacement reactions of boron trihalides from their trimethylamine aducts show that the order of acceptor power is BBr3>BCl3>BF3>1/2(B2H6). This order agrees with recent theoretical calculations and dipole moment, calorimetric, and infrared measurements on boron trihalide complexes with other…

Measurements have been made on the angular dependence of the magnetoresistance effect and the Hall effect on oriented w-type indium antimonide samples. The measurements were taken at room temperature and liquid air temperature using a magnetic field strength of about…

The observation of delayed proton emission is reported. Bombardment of both aluminum and silicon with 97-Mev protons leads to the emission of delayed proton energy groups from to 5 Mev. They follow the beta decay of S25 (T1/2 about 0.3…

The delayed-proton precursor 33AR has been produced by proton bombardment of a lithium chloride target in the internal beam of the McGill synchrocyclotron. The Half-life of 33Ar was measure to be (178±10) msec. to explain the delayed proton spectrum, two…

Rotational energy levels of axially asymmetric nuclei have been calculated in the manner of Davydov and Filippov, and a comparison with experiment shows good quantitative agreement. It is suggested that agreement may be improved by introducing the Bohr-Mottelson vibration-rotation interaction…

Proton n.m.r. spectra of trimethylamine adducts of the boron trihalides and borane have been measured in chloroform solution. Chemical shifts of methyl protons relative to tetramethylsilane decrease in the order: BBr3 > BCl3 > BH3 > BF3, suggesting that this…

Measurements of the spin-spin relaxation time and of the effective, lattice-induced, transition probabilities are reported for magnetically dilute potassium chromicyanide in chemically analyzed concentrations ranging nfrom 0.06 to 1.5%. In these measurements the c-axis of the cobalticyanide matrix was parallel…
