Lately many interactive methods to solve multiple objective problems were proposed. One of these, the method developed by S. Zionts and J. Wallenius, looks particularly interesting. This paper takes a closer look at this method and reports on the results of an experiment set up in order to test the method. 相似文献

Simultaneous production of K1o (892) and Δ++(1236) in the reaction K+p→K+π+π−p from 4.3 to 5.0 GeV/c

The reaction from a K+d experiment with the CERN 2 m bubble chamber at 4.6 GeV/c is compared with the reaction from a K+p experiment at the same energy. In addition, predictions of an absorption model, a Regge pole model and a quark model for the production and decay characteristics of the reaction are tested with the combined statistics of the K+d experiment and three K+p experiments between 4.3 and 5.0 GeV/c. 相似文献

We report the observation of double diffraction dissociation in the process p + p → (pπ+π?) + X at √s of 45 GeV and momentum transfer in the ?t range 0.15?0.53 GeV2 at the CERN ISR. The relative rates for elastic, single and double dissociation reactions measured here are found to agree with the prediction of Pomeron factorization. 相似文献

From a search for e±μ± production at the CERN ISR an upper limit of 0.92 μb (95% confidence limit) has been inferred for σ·Be·Bμ for the reaction . 相似文献

The exclusive reaction pp→Λ°K+p has been studied at 0.1<?tpp<0.6 GeV2 and energies √s=45 GeV and 53 GeV at the CERN ISR. Diffractive excitation p→Λ°K+ occurs predominantly in the mass range M(Λ°K+)≈2.1 GeV and peaks at 1.7 GeV. The cross section for pp→Λ°K+p is 10±3μb for M(Λ°K+)<2.5 GeV, and the tpp dependence is exp (bt) with b=7.0±0.5 GeV?2. 相似文献

Structural and solid-state changes of piroxicam in its crystalline form under mechanical stress were investigated using cryogenic grinding, powder X-ray diffractometry, diffuse-reflectance solid-state ultraviolet-visible spectroscopy, variable-temperature solid-state (13)C nuclear magnetic resonance spectroscopy, and solid-state diffuse-reflectance infrared Fourier transform spectroscopy. Crystalline piroxicam anhydrate exists as colorless single crystals irrespective of the polymorphic form and contains neutral piroxicam molecules. Under mechanical stress, these crystals become yellow amorphous piroxicam, which has a strong propensity to recrystallize to a colorless crystalline phase. The yellow color of amorphous piroxicam is attributed to charged piroxicam molecules. Variable-temperature solid-state (13)C NMR spectroscopy indicates that most of the amorphous piroxicam consists of neutral piroxicam molecules; the charged species comprise only about 8% of the amorphous phase. This ability to quantify the fractions of charged and neutral molecules of piroxicam in the amorphous phase highlights the unique capability of solid-state NMR to quantify mixtures in the absence of standards. Other compounds of piroxicam, which are yellow, are known to contain zwitterionic piroxicam molecules. The present work describes a system in which proton transfer accompanies both solid-state disorder and a change in color induced by mechanical stress, a phenomenon which may be termed mechanochromism of piroxicam. 相似文献
