A New Algorithm for Privacy-Preserving Horizontally Partitioned Linear Programs
Journal of Mathematics, 2021 In a linear programming for horizontally partitioned data, the equality constraint matrix is divided into groups of rows. Each group of the matrix rows and the corresponding right-hand side vector are owned by different entities, and these entities are ...

Gait Analysis for a Tiltrotor: The Dynamic Invertible Gait
Robotics, 2022 A conventional feedback-linearization-based controller, when applied to a tiltrotor (eight inputs), results in extensive changes in tilting angles, which are not expected in practice. To solve this problem, we introduce the novel concept of “UAV gait” to

Invertible Concept-based Explanations for CNN Models with Non-negative Concept Activation Vectors [PDF]
AAAI Conference on Artificial Intelligence, 2020 Convolutional neural network (CNN) models for computer vision are powerful but lack explainability in their most basic form. This deficiency remains a key challenge when applying CNNs in important domains.

Finding Bit-Based Division Property for Ciphers with Complex Linear Layers
IACR Transactions on Symmetric Cryptology, 2020 The bit-based division property (BDP) is the most effective technique for finding integral characteristics of symmetric ciphers. Recently, automatic search tools have become one of the most popular approaches to evaluating the security of designs against

An analogue of Serre’s conjecture for a ring of distributions
Topological Algebra and its Applications, 2020 The set 𝒜 := δ0+ 𝒟+′, obtained by attaching the identity δ0 to the set 𝒟+′ of all distributions on with support contained in (0, ∞), forms an algebra with the operations of addition, convolution, multiplication by complex scalars.

On the Inverting of a General Heptadiagonal Matrix [PDF]
British Journal of Applied Science & Technology, 2016 In this paper, we developed new numeric and symbolic algorithms to find the inverse of any nonsingular heptadiagonal matrix. Symbolic algorithm will not break and it is without setting any restrictive conditions. The computational cost of our algorithms is $O(n)$.

Degree-inverting involutions on matrix algebras [PDF]
Linear and Multilinear Algebra, 2017 Let $F$ be an algebraically closed field of characteristic zero, and $G$ be a finite abelian group. If $A=\oplus_{g\in G} A_g$ is a $G$-graded algebra, we study degree-inverting involutions on $A$, i.e., involutions $*$ on $A$ satisfying $(A_g)^*\subseteq A_{g^{-1}}$, for all $g\in G$.

On the conjecture of the norm Schwarz inequality [PDF]
, 2016 For any positive invertible matrix $A$ and any normal matrix $B$ in $M_{n}({\Bbb C})$, we investigate whether the inequality $ ||A\sharp (B^{*}A^{-1}B)||\geq ||B|| $ is true or not, where $\sharp$ denotes the geometric mean and $||\cdot||$ denotes the ...

Stochastic Stability of Lyapunov Exponents and Oseledets Splittings for Semi‐invertible Matrix Cocycles [PDF]
, 2013 We establish (i) stability of Lyapunov exponents and (ii) convergence in probability of Oseledets spaces for semi‐invertible matrix cocycles subjected to small random perturbations.

Classical R-matrix structure for the Calogero model [PDF]
, 1992 A classical R-matrix structure is described for the Lax representation of the integrable n-particle chains of Calogero-Olshanetski-Perelo\-mov. This R-matrix is dynamical, non antisymmetric and non-invertible. It immediately triggers the integrability of
