    EXSENSEL - a rule-based approach to selection of sensors for process variables (1996)

    Notes: A novel expert-system-based method for selection of sensors for process variables is presented. EXSENSEL (expert system based sensor selection) deals with 12 process variables and currently has 94 rules in its knowledge base. Despite its large knowledge base, users have to answer a set of only a few questions regarding a particular process variable, which is selected from a menu of 12 variables. A general description of the chosen process variable can be viewed before invoking the rules. Once a sensor has been selected, a brief write up on that particular sensor is also available on user's request. EXSENSEL is the successor to TRANSELEX, which is a single expert system for selection of transducers in the area of temperature, pressure, and flow measurement.

    Notes: A five-noded thirteen DOF horizontally curved beam element with or without an elastic base is presented. One set of fourth-degree Lagrangian polynomials in natural co-ordinates is used for interpolation of beam geometry and vertical displacement while the angles of transverse rotation and twist are interpolated by another set of third-degree polynomials. For elastic subgrade, the reactive forces offered at any point are assumed to be proportional to the corresponding displacements at that point. The effect of shear deformation is accounted for in the stiffness matrix. In mass matrix evaluation, for dynamic problems, translational as well as rotary intertias have been considered and studied separately. For numerical integration of the stiffness matrix, a four-point Gaussian scheme has been found to be adequate. Numerical results for a number of sample problems and their comparison with analytical solutions have been presented for circular as well as for non-circular curved beams. Displacements, bending moment and torque for static loading with or without elastic foundation, as well as natural frequencies and mode shapes are computed for different cases. Examples include the problem of a cantilever beam of spiral geometry with different parametric values of the spiral and the agreement with the analytical results establishes the efficacy of the element. The performance of the element has been found be be excellent in both static and dynamic conditions. Sufficient details are presented so that the formulation may be readily used. It is hoped that the large number of numerical illustrations will elucidate the validity and the range of applicability of the element and will also serve as benchmark for future researchers. © 1997 by John Wiley & Sons, Ltd.
