Rule based diagnostic system with dynamic alteration capability

Abstract: Sensor based diagnostic apparatus for performing on-line realtime monitoring of an industrial or other operating system. The diagnostic apparatus has a rule network for propagation of belief leading to one or more possible malfunctions of equipment in the operating system. The propagation of belief is dynamically altered as a function of the operating conditions of the sensors themselves.

A Solution for the Finite Journal Bearing and its Application to Analysis and Design: III

Abstract: This is the concluding paper in a series. The effect of modifying the assumptions in Parts I and II to include the influence of rupture of the film is discussed in detail. Numerical solutions which account for film rupture are presented for Reynolds' equation in the form of performance curves and tabulated data for centrally-loaded bearings having arcs of 360°, 180°, 120° and 60° for L/D values of ∞ 1, 1/2 and 1/4. The method of obtaining the computer solutions is discussed in the appendix and the results compared with similar work of other investigators. Presented as an American Society of Lubrication Engineers paper at the Lubrication Conference held in Toronto, Canada, October, 1957.

Estimations on J-integral and tearing modulus T from a single specimen test record

Abstract: This paper presents methods for evaluating the J-integral and the tearing moduli from a single test record. Several different aspects of the problem have been combined in this work. An overview of the conditions for separability of the load into multiplicative functions of displacement and crack length as well as for the existence of it-factors is presented. The consequences of expressing J by a Merkle-Corten type formula are explored in terms of the crack increment, da, the tearing modulus, T, and J itself, including the case of growing cracks. A simple method is suggested to obtain the correct J for crack growth and T from nothing more than the test record itself; the procedure is applied to available experimental data and the results are compared with those obtained by other formulae. Additional physical interpretation is given on the T m a t -versus-T a p p stability criterion and the remaining compliance capacity C C R is defined.

Modification of polymer-gel structures

Abstract: In metal-organic driven systems, gelling occurs as a result of the formation of a polymeric network by simultaneous and competing chemical reactions. The resultant polymeric units consist of an inorganic network, similar to that of oxide glasses, framed by hydroxyl and organic groups. The extent of polymerization as well as the structure of the polymeric network are determined by the hydrolysis and polymerization reactions. By controlling the kinetics of these reactions, it is possible to alter the polymeric structure of the gels. The effect of these molecular-structural variations in the gel is maintained in the glass and ceramic materials derived from the gels, thus allowing property modification of ceramic materials without compositional variations.
