Inventory or material balance control is an important part of process control. In the literature, many rules have been proposed to held in designing such systems, but their justification is often unclear. The main contribution of this paper is to proposed the more general selfconsistency rule for evaluating inventory control systems. Consistency means that the steadystate mass balances (total, ...

The motion of stars in the gravitational potential of a triaxial galaxy is generically chaotic. However, the timescale over which the chaos manifests itself in the orbital motion is a strong function of the degree of central concentration of the galaxy. Here, chaotic diffusion rates are presented for orbits in triaxial models with a range of central density slopes and nuclear black-hole masses....

Even though one usually calculates capacitor losses with a complex epsilon it still oÆends the principle of a constant speed of light. Maxwell’s term c2 = 1/"·μ suggests a physically inexplicable complex speed. By such an oÆence against basic principles every physicist is asked to search and to repair the mistake in the textbooks. The contribution clearly explains how vortex losses occur instea...

This paper studies collective choice rules whose outcomes consist of a collection of simultaneous decisions, each one of which is the only concern of some group of individuals in society. The need for such rules arises in different contexts, including the establishment of jurisdictions, the location of multiple public facilities, or the election of representative committees. We define a notion ...

Effect of electronegative substituents on ring opening of [2.2.2]propellane was examined by quantum chemical calculations at CASSCF and CASPT2 level of theory. Comparison of the results with those obtained with MR-AQCC calculations indicated that calculations beyond CASSCF level were needed for reliable description of the process. Calculations show a strong effect of fluorination on the central...

Density functional calculations have been performed on the excited states of Cr(CO)6. In contrast to the generally accepted assignment of the spectrum by Gray and Beach1,2 but in agreement with recent CASSCF/CASPT2 calculations by Pierloot et al.3 we find the low-intensity absorption at the low-energy side of the first charge-transfer (CT) band not to be due to ligand-field (LF) excited states,...

We propose simple randomized strategies for sequential prediction under imperfect monitoring, that is, when the forecaster does not have access to the past outcomes but rather to a feedback signal. The proposed strategies are consistent in the sense that they achieve, asymptotically, the best possible average reward. It was Rustichini [11] who first proved the existence of such consistent predi...
