Representation and usage of knowledge for initialization of accelerator control equipment

A knowledge based application, called SETUP, to initialize and diagnose the CERN/PS accelerators' control equipment is described. The object model and the general features of control algorithms are presented, together with their relation to the knowledge description of the setting up of the system. The different ways of the integration of the SETUP in the control system are outlined

Oxidation of n-С5-С8 hydrocarbons and cyclohexane in a reactor with barrier discharge. P. 2. Simulating cyclohexane oxidation reaction

Numerical model of hydrocarbon oxidation kinetics in a reactor with barrier discharge has been proposed by the example of cyclohexane oxidation reaction. The results of calculations with the use of barrier discharge surface model showed that electron energy and other discharge characteristics in pure oxygen and in the mixture of oxygen with cyclohexane vapors slightly differ that allowed using a simplified model of homogeneous discharge for simulating cyclohexane oxidation reaction. The results of calculation showed good fit with the experimental dat

Experimental Investigations of Changes in beta-decay rate of Co-60 and Cs-137

Results of simultaneous measurements of beta-decay rate with the aid of Ge(Li)-detectors performed at two laboratories 140km apart (INR RAS, Troitsk, Co-60, and JINR, Dubna, Cs-137) during a period from 15.03.2000 till 10.04.2000, are presented. Regular deviations of the count rate of gamma-quanta following the beta-decay of $\sim$ 0.7% (INR RAS, Co-60) and $\sim$ 0.2% (JINR, Cs-137) from the statistical average, are observed. The analysis of extremum deviations of gamma-quanta count rate shows that the set of directions of tangents to the Earth's parallels of latitude at the extremum points of trajectories of motion in the space of each laboratory clearly forms three separate compact subsets of directions which agree, for two laboratories, to an accuracy of $\pm10^\circ$. This phenomenon is shown not to be explained on the basis of traditional notion. A possible explanation is suggested basing on the hypothesis that there exists a new anisotropic interaction caused by the cosmological vectorial potential \textbf{A}$_{\rm g}$, a new fundamental constant having, according to the experiments carried out, the coordinate of right ascension $\alpha \approx 285^\circ$ in the second equatorial system. This is in agreement with earlier experiments.Comment: 13 pages, LaTeX2e, 4 PS figure

The research of uranium monoxide-oxide dissolution process in nitric acid

The kinetics of concentrates of uranium monoxide-oxide dissolution process by nitric acid solutions of 5...9 mole/l in the range of 11...90 °C has been studied. It is stated that initial nitric acid concentration increasing results in some uranium dissolution degree increasing only at the first process stage. Temperature increasing significantly raises uranium dissolution degree at the first stage as well. Uranium dissolution degree increases for all studied temperatures with increasing of the process period. The main feature of the studied process is that while dissolving uranium monoxide-oxide the behavior of iron, molybdenum, silicon additives is adequate to that of uranium. The equation of the reducing sphere describes the uranium leaching process from its nitric acid concentrate
