Decomposition of multi-valued logical functions and its application to threshold networks

publisherIn this paper, first, the theoretical aspects of the decomposition of an arbitrary multi-valued logical function in terms of several essentially simpler logical functions are described. Secondly, on the basis of this theory, a method for the realization of three-valued logical functions by networks of threshold gates is proposed. Lastly, examples are worked out in detail to illustrate this method.departmental bulletin pape

Lectures as Services from the viewpoint of customer delight

application/pdfAs the service-oriented economy grows, it is possible to perceive educational activities as a part of service activities too. However, though we think “educational activities = service activities”, actually how can we satisfy our students which are our customers? This paper focuses on customer delight and describes lectures as services which might make it possible to attract the delight of students which the author is actually teaching.departmental bulletin pape

Miscible viscous fingering with a chemical reaction involving precipitation

We experimentally investigated the effects of a chemical reaction involving precipitation on the miscible viscous fingering pattern formed in a Hele-Shaw cell. The precipitation concentration, the ratio of the reactant concentrations initially included in the more- and less-viscous liquids, and the Peclet number were varied. For a Peclet number at the stoichiometric ratio the precipitation had significant effects on the fingering pattern when its concentration exceeded a threshold value. Interestingly, the type of effect of the precipitation on the pattern depended on its concentration. At moderate concentration, a straight-shaped finger was observed. At high concentration, the finger was bent in an almost perpendicular direction. The effect of precipitation on the pattern also depended on the ratio of reactant concentrations.application/pdfjournal articl

Mass and size effects on the transport properties of molten salts

The mass and size dependencies of the ionic transport processes were studied by molecular dynamics calculations on the model fluid interacting through repulsive soft‐core and the Coulomb potentials. The mass difference between anion and cation significantly affects the ionic transport processes. On the contrary, the change in the time evolution of the processes due to size difference between unlike ions is comparatively small. A perturbation treatment for the mass effect was developed to describe the velocity autocorrelation function, the electrical current autocorrelation function, and corresponding transport properties.application/pdfjournal articl

Effects of Location of Baffle and Clearance between Baffle and Vessel Wall on Isolated Mixing Regions

The effects of the location of the baffle on mixing pattern in laminar mixing is shown in this study. Decolorization experiments were conducted based on an oxidation-reduction reaction to investigate the mixing pattern. As a result, isolated mixing regions (IMR) like doughnut-rings were eliminated by setting the baffle at the optimum location, where the baffle and the IMR crossed each other. The velocity profile was measured by using particle image velocimetry under the baffle condition. The IMR was dissipated due to making unstable circulation flow when the baffle was placed with clearance between the baffle and the wall. It was shown that using conventional mixing equipment can eliminate the IMR easily by placing the baffle with clearance.application/pdfjournal articl
