On projective and affine hyperplanes

open access: yesJournal of Combinatorial Theory, Series A, 1980
AbstractWe study projective and affine factors in 2-coverings and associate canonically a projective space of order 2 and an affine space of order 3 to each Steiner triple system and an affine space of order 2 to each Steiner quadruple system.

The Gauss-Seidel fast affine projection algorithm

open access: yes
In this paper we propose a new stable fast affine projection algorithm based on Gauss-Seidel iterations (GSFAP). We investigate its implementation using the logarithmic number system (LNS) and compare it with two other fast affine projection (FAP ...

Analysis of Transient and Steady-State Behavior of a Multichannel Filtered-x Partial-Error Affine Projection Algorithm

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2007
The paper provides an analysis of the transient and the steady-state behavior of a filtered-x partial-error affine projection algorithm suitable for multichannel active noise control.

Multichannel Active Noise Control Based on Filtered-x Affine Projection-Like and LMS Algorithms with Switching Filter Selection

open access: yesApplied Sciences, 2019
Affine projection (AP) algorithms have been demonstrated to have faster convergence speeds than the conventional least mean square (LMS) algorithms. However, LMS algorithms exhibit smaller steady-state mean square errors (MSEs) when compared with affine ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Sliding Window Generalized Kernel Affine Projection Algorithm Using Projection Mappings

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
Very recently, a solution to the kernel-based online classification problem has been given by the adaptive projected subgradient method (APSM). The developed algorithm can be considered as a generalization of a kernel affine projection algorithm (APA ...

Mixed Norm Constrained Sparse APA Algorithm for Satellite and Network Echo Channel Estimation

open access: yesIEEE Access, 2018
We propose an improved proportionate affine projection algorithm (PAPA), which is realized by integrating a hybrid-norm constraint into the affine projection algorithm (APA) to estimate the cluster sparse signals that are happened in satellite and ...

Order in Affine and Projective Geometry [PDF]

open access: yesCanadian Mathematical Bulletin, 1963
In this note we give a characterisation of ordered skew fields by certain properties of the negative elements.Properties of negative elements of a skew field K are then interpreted as statements about "betweenness" in any affine geometry over K, or as statements about "separation ...
