(Abstract) In [6] Prior proposed a modal calculus, M IP C, which is an extension of the intuitionist propositional calculus. This system, which I call S 5 IC, turns out to be the intuitionist analogue of Lewis's S 5 in the sense that 1) S 5 IC plus A ∨ ¬A is equivalent to S 5 , 2) collapsing the modal operators yields Heyting's calculus. The question as to whether S 5 IC is to be considered ana...

The diagnostic and research aspects of compressor blade fatigue detection have been elaborated in the paper. The real maintenance and overhaul problems and characteristic of different modes of metal blade fatigue (LCF, HCF, and VHCF) have been presented. The polycrystalline defects and impurities influencing the fatigue, along with their related surface finish techniques, are taken into account...

This is a review. with historical and critical comments, of a paper b) I. E. Orlov from 1928, which eivcs the oldest known axiomatization of the implicationnegation fragment of the rclcvant logic R. Orlov’s paper also l’omshadow the modal translation of systems with an intuitionistic negation into %-type extensions of systems with a classical. involutive. negation. Orlov introduces the modal po...

The modal testing has proven to be an effective and non-destructive test method for estimation of the dynamic stiffness and damping constant. The aim of the present paper is to investigate the modal response of stiffened Fiber Metal Laminated (FML) circular cylindrical shells using experimental and numerical techniques. For this purpose, three types of FML-stiffened shells are fabricated by a s...

The temperature of the bevel gear tooth surface will increase greatly because its special structure. Modal is characteristic reaction In order to design and manufacture higher quality aerial gears, it necessary study modal gears under action field. Firstly, a field calculation model established according heat transfer theory. Then, based on traditional linear theory, analysis influence was cons...

In this work, we examine experimentally the resonance of a sessile drop with a square footprint (square drop) on a flat plate. Two families of modal behaviors are reported. One family is identified with the modes of sessile drops with circular footprints (circular drop), denoted as "spherical modes." The other family is associated with Faraday waves on a square liquid bath (square Faraday waves...

It is shown how the temporal-modal system of events TM (axiomatized in Appendix) allows for avoidance logical determinism without rejection principle bivalence. The point that temporal and modal parts are so inter-related modalities in-the-real-world-inherent independently whether they concern actual or only possible events. Though formulated a tenseless language, whose interpretation does not ...

this study contains the identification of modal dynamic properties of a 3-story large-scale steel test frame structure through shaking table measurements. shaking table test is carried out to estimate the modal properties of the test frame such as natural frequencies, damping ratios and mode shapes. among many different model structures, arx (auto recursive exogenous) model structure is used fo...

The over-voltage phenomenon is usually described using the traveling wave and reflection phenomena in variable speed drive system. A voltage pulse, initiated at the inverter, being reflected at the motor terminals due to a mismatch between the surge impedance of the motor and the cable. In this paper, resistance, inductance and capacitance of the cable and the motor windings are obtained experi...
