We present a Bayesian decision theoretic approach for developing replacament strategies. In so doing, we consider a semi-parametric model to describe the failure characteristics of systems by specifying a nonparametric form for cumulative intensity function and by taking into account effect of covariates by a parametric form. Use of a gamma process prior for the cumulative intensity function co...

Fractional Fornberg-Whitham equation has a vast application in physics. There exist various investigations for the above problem by considering the variables and parameters as crisp/exact. In practice, we may not have these parameters exactly but those may be known in some uncertain form. In the present paper, these uncertainties are taken as interval/fuzzy and the authors proposed here a new m...

Most preferred ordered weighted average (MP-OWA) operator is a new kind of neat (dynamic weight) OWA operator in the aggregation operator families. It considers the preferences of all alternatives across the criteria and provides unique aggregation characteristics in decision making. In this paper, we propose the parametric form of the MP-OWA operator to deal with the uncertainty preference inf...

In this paper, a new adaptive control law combining nonparametric and parametric estimators is proposed to control stochastic d-dimensional discrete-time nonlinear models of the form Xn+1 = f(Xn) + Un + εn+1. The unknown function f is assumed to be parametric outside a given domain of Rd and fully nonparametric inside. The nonparametric part of f is estimated using a kernel-based method and the...

This paper discusses a local parametric modeling by the use of U-divergence in a statistical pattern recognition. The class of U-divergence measures commonly has an empirical loss function in a simple form including Kullback-Leibler divergence, the power divergence and mean squared error. We propose a minimization algorithm for parametric models of sequentially increasing dimension by incorpora...

15 Parametric Curves And Surfaces 15.1 Parametric Curves Designing Curves • We don’t want only polygons. • Curves are used for design. Users require a simple set of controls to allow them to edit and design curves easily. • Curves should have infinite resolution, so we can zoom in and still see a smooth curve. • We want to have a compact representation. Parametric functions are of the form x(t)...

We review the transition now being undertaken from 2D drafting to 3D parametric modeling and the development of Building Information Modeling (BIM). We examine the functionality of BIM platforms, using an example from precast concrete structures. We formulate the development of parametric modeling of building systems from the context of SFB modeling and characterize most parametric modeling as ...

Extensions of the ML type system, based on constrained type schemes, have been proposed for languages with overloading. Type inference in these systems requires solving the following satissability problem. Given a set of type assumptions C over nite types and a type basis A, is there is a substitution S that satisses C in that A ` CS is derivable? Under arbitrary overloading, the problem is und...
