Joint economic design of X̄ and R control charts for processes subject to two independent assignable causes
(IIE Transactions (Institute of Industrial Engineers), 1993-11-01) [Artigo]
A model for the joint economic design of X̄ and R control charts is developed. This model assumes that the process is subject to two assignable causes. One assignable cause shifts the process mean; the other shifts the ...
Exact solution for a three-dimensional three-body problem with harmonic interactions
(European Journal of Physics, 1993-12-01) [Artigo]
The three-dimensional three-body problem with non-equal masses interacting through pairwise harmonic forces of non-equal strengths is analysed. It is shown that the Jacobi coordinates per se do not decouple this problem ...
MAPPING CORRELATION-FUNCTIONS OF SCHWINGER AND AXIAL MODELS
(Journal of Physics G: Nuclear and Particle Physics, 1993-08-01) [Artigo]
We show that all Green's functions of the Schwinger and axial models can be obtained one from the other. In particular, we show that the two models have the same chiral anomaly. Finally it is demonstrated that the Schwinger ...
Conditionally exactly soluble class of quantum potentials
(Physical Review A, 1993-12-01) [Artigo]
We present a different class of quantum-mechanical potentials. These are midway between the exactly solvable potentials and the quasiexactly ones. Their fundamental feature is that one can find the entire s-wave spectrum ...
A diquark model for baryon spectroscopy
(Zeitschrift fur Physik C: Particles and Fields, 1993-06-01) [Artigo]
A quark-diquark approximation is used to investigate the mass spectroscopy of the spin-1/2 baryons belonging to the SU(3)-flavor group in a nonrelativistic potential approach. The baryon spectra obtained are confronted ...
A constraints generator in structural determination by microcomputer
(Computers & Chemistry, 1993-12-01) [Artigo]
We present a new expert system: a constraints generator for structure determination of natural products. The constraints that the system furnishes are: skeleton (reliability: 95%), large substructures (reliability: 98%) ...
