The inputioutput relationship of a class of crisp-type fuzzy logic controllers (FLCs) using parametric t-norm-sum-gravity inference method is examined. The explicit mathematical form of reasoning surface using Dubois and Prade’s parametric t-norm is addressed. Reasoning surfaces of crisp-type FLCs are proved to be composed of a two-dimensional multilevel relay and a local position-dependent non...

A composition and analysis technique was developed for investigation of infinite Petri nets with regular structure, introduced for modeling networks, clusters and computing grids, that also concerns cellular automata and biological systems. A case study of a square grid structure composition and analysis is presented. Parametric description of Petri nets, parametric representation of infinite s...

In multi-form segment synthesis, output speech is constructed by splicing waveform segments with statistically modeled and regenerated parametric speech segments. The fraction of model-derived segments is called model-template ratio. The motivation of this work is to further increase flexibility of multi-form synthesis maintaining high speech quality for high model-template ratios. An approach ...

Given A spline curves and A patch surfaces that are implicitly de ned on triangles and tetrahedra we determine their NURBS representations We provide a trimmed NURBS form for A spline curves and a parametric tensor product NURBS form for A patch surfaces We concentrate on cubic A patches providing a C continuous surface that interpolates a given triangulation together with surface normals at th...

in this article the general non-symmetric parametric form of the incremental secant stiffness matrix for nonlinear analysis of solids have been investigated to present a semi analytical sensitivity analysis approach for geometric nonlinear shape optimization. to approach this aim the analytical formulas of secant stiffness matrix are presented. the models were validated and used to perform inve...

Identification of protein complexes from proteomic experiments is crucial to understand not only their function but also the principles of cellular organization. Advances in experimental techniques have enabled the construction of large–scale protein–protein interaction networks, and computational methods have been developed to analyze high–throughput data. In most cases several parameters are ...

In the conventional approach to these questions the demand analyst chooses a parametric form for the underlying utility function and derives the associated set of parametric demand functions, which are then fitted to the data using some econometric technique. The resulting parameter estimates can then be tested to see if they conform to the restrictions imposed by the utility maximization model...

We address the existence and properties of one-dimensional solitons maintained by localized parametric gain in focusing and defocusing lossy nonlinear media. Localized parametric gain supports both fundamental and multipole solitons. We found that the family of fundamental solitons is partly stable in focusing nonlinear medium, and completely stable in defocusing medium, while all higher-order ...
