A specific form of Grothendieck inequality for the 2-dimensional case, with applications to c-asterisk algebras. [PDF]

open access: yes, 1994
We characterize bilinear forms V on such that V(e, e) = V = 1 in terms of their matrices. For such V we prove that |V(x, y)|2≦φ(|x|2)ψ(|y|2) for all x, y, where φ(x)= V(x, e), ψ(y) = V(e, y).

Adaptive diagnosis of the bilinear mechanical systems [PDF]

open access: yes, 2009
A generic adaptive approach is proposed for diagnosis of the bilinear mechanical systems. The approach adapts the free oscillation method for bilinearity diagnosis of mechanical systems.

Bilinear Form and Two Bäcklund Transformations for the (3+1)-Dimensional Jimbo-Miwa Equation

open access: yesAbstract and Applied Analysis, 2015
With Bell polynomials and symbolic computation, this paper investigates the (3+1)-dimensional Jimbo-Miwa equation, which is one of the equations in the Kadomtsev-Petviashvili hierarchy of integrable systems.

Lax integrability and soliton solutions of the (2 + 1)- dimensional Kadomtsev– Petviashvili– Sawada–Kotera– Ramani equation

open access: yesFrontiers in Physics, 2022
In this paper, a new (2 + 1)-dimensional nonlinear evolution equation is investigated. This equation is called the Kadomtsev–Petviashvili–Sawada–Kotera–Ramani equation, which can be seen as the two-dimensional extension of the Korteweg–de Vries–Sawada ...

Determination of the bilinear stress-crack opening curve for normal- and high-strength concrete [PDF]

open access: yes, 2008
An improved version of the method proposed to ACI committee 446 and to RILEM TC 187-SOC to determine the fracture parameters of concrete is applied in this study to several mixtures of normal and high-strength concretes.

A Bilinear Form for Spin Manifolds [PDF]

open access: yesTransactions of the American Mathematical Society, 1987
Let \(M^{2j+2}\) be a closed Spin manifold, and let [, ] be the symmetric bilinear form on \(H^ j(M; {\mathbb{Z}}_ 2)\) defined by \([x,y]=\). In this paper, the authors study [, ] and the resulting cobordism invariants. For example, the rank modulo 2 of [, ] on integral cohomology is \(\) when dim M\(=8k+2\).

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Structure vs Randomness for Bilinear Maps

open access: yesDiscrete Analysis, 2022
Structure vs randomness for bilinear maps, Discrete Analysis 2022:12, 21 pp. A _tensor_ can be thought of as a higher-dimensional analogue of a matrix (where a matrix is 2-dimensional).

Dynamics of multi-solitons, multi-lumps and hybrid solutions in (2+1)-dimensional Korteweg–de Vries–Sawada–Kotera–Ramani equation

open access: yesResults in Physics, 2022
The (2+1)-dimensional Korteweg–de Vries–Sawada–Kotera–Ramani (KdVSKR) equation is proposed by extending one dimension of the (1+1)-dimensional KdVSKR equation.

Nonlinear unmixing of hyperspectral images using a generalized bilinear model [PDF]

open access: yes, 2011
Nonlinear models have recently shown interesting properties for spectral unmixing. This paper studies a generalized bilinear model and a hierarchical Bayesian algorithm for unmixing hyperspectral images. The proposed model is a generalization not only of
