Gradient estimates and the fundamental solution for higher-order elliptic systems with lower-order terms

open access: yesAdvanced Nonlinear Studies, 2023
We establish the Caccioppoli inequality, a reverse Hölder inequality in the spirit of the classic estimate of Meyers, and construct the fundamental solution for linear elliptic differential equations of order 2m2m with certain lower order terms.

An existence result for quasilinear parabolic systems with lower order terms

open access: yesMathematical Modelling and Analysis, 2021
In this paper we prove the existence of weak solutions for a class of quasilinear parabolic systems, which correspond to diffusion problems, in the form where Ω is a bounded open domain of be given and The function v belongs to is in a moving and ...

On the Cauchy Problem for Pseudohyperbolic Equations with Lower Order Terms

open access: yesMathematics, 2023
We consider a class of strictly pseudohyperbolic equations with lower order terms. The solvability of the Cauchy problem in Sobolev spaces with special weights is established. The uniqueness of the solution is proven and estimates are obtained.

Speed and surge control for a lower order centrifugal compressor model [PDF]

open access: yesModeling, Identification and Control, 1998
A model of a variable speed centrifugal compression system is presented. The model is based on the work of Greitzer (1976), but the compressor characteristic is developed by modelling the losses in the compressor. For surge control, a close coupled valve

Lower Order Krawtchouk Moment-Based Feature-Set for Hand Gesture Recognition

open access: yesAdvances in Human-Computer Interaction, 2016
The capability of lower order Krawtchouk moment-based shape features has been analyzed. The behaviour of 1D and 2D Krawtchouk polynomials at lower orders is observed by varying Region of Interest (ROI).
