In this work, we investigate a model-order reduction scheme for polynomial systems. We begin with defining the generalized multivariate transfer functions system. Based on this, aim at constructing reduced-order system, interpolating defined given set of interpolation points. Furthermore, provide method, inspired by Loewner approach linear and (quadratic-)bilinear systems, to determine good-qua...

Accurate case predictions are essential for efficient public health management and resource allocation since the COVID-19 pandemic has had a substantial impact on economies global health. Using polynomial regression, machine learning technique that fits function to data, this research seeks create predictive model future cases. The takes into consideration elements such as population density, h...

In this work, we explore a three-dimensional formulation of the polynomial affine model gravity, which is that extends general relativity by relaxing equivalence principle through exclusion metric from set fundamental fields. particular, in an attempt to gain insight role torsion and nonmetricity gravitational models, consider homogeneous isotropic cosmological for their solutions are classifie...

one of the most valuable and important application of artificial satellites in geodetic sciences is recovery of the earth's gravity field. orbits of satellites either gravimetric or nongravimetric are analyzed to improve the earth's gravity field. gravimetric satellites are launched at low altitudes to observe gravity field in more detail. grace twin satellites are the second spacecra...

design of crystal-like lattices can be achieved by using some net operations. hypothetical networks, thus obtained, can be characterized in their topology by various counting polynomials and topological indices derived from them. the networks herein presented are related to the dyck graph and described in terms of omega polynomial and piv polynomials.

biodegradation of phenanthrene (phe) was studied in aqueous culture to demonstrate the potential of the mixed culture in degrading high concentration of phe. the experiments were conducted to monitor biodegradation of phenanthrene for duration of 6 days. biodegradation of phe was successfully achieved in low and middle concentration by the isolated mixed culture. a full factorial central compos...
