Majority of the sensors for underwater application use acoustic waves for detection, communication and navigation of submersibles. Hydrophone, used for sensing acoustic signals in water, has piezoelectric material within which responds to acoustic pr

In this paper we demonstrate the use of Bezier projection to alleviate locking phenomena in structural mechanics applications of isogeometric analysis. Interpreting the well-known B projection in two different ways we develop two formulations for loc

In this paper we develop the isogeometric Bezier dual mortar method. It is based on Bezier extraction and projection and is applicable to any spline space which can be represented in Bezier form (i.e., NURBS, T-splines, LR-splines, etc.). The approac

In this paper we develop an isogeometric Bezier dual mortar method for coupling multi-patch Kirchhoff–Love shell structures . The proposed approach weakly enforces the continuity of the solution at patch interfaces through a dual mortar method and

The skewness of the first time derivative of a pressure waveform, or derivative skewness, has been used previously to describe the presence of shock-like content in jet and rocket noise. Despite its use, a quantitative understanding of derivative ske

In this paper, we present an algorithm to construct enriched Bezier dual basis functions that can reproduce higher-order polynomials. Our construction is unique in that it is based on Bezier extraction and projection, allowing it to be used for tenso

In this paper we introduce the hierarchical B-spline complex of discrete differential forms for arbitrary spatial dimension. This complex may be applied to the adaptive isogeometric solution of problems arising in electromagnetics and fluid mechanics

Difficulties arise in attempting to discern the effects of nonlinearity in near-field jet-noise measurements due to the complicated source structure of high-velocity jets. This article describes a measure that may be used to help quantify the effects

We introduce B\'{e}zier projection as an element-based local projection methodology for B-splines, NURBS, and T-splines. This new approach relies on the concept of B\'{e}zier extraction and an associated operation introduced here, spline reconstructi
