Chromaticity-Adaptive Generalized Spatial Modulation for MIMO VLC With Multi-Color LEDs
In this paper, we propose a chromaticity-adaptive generalized spatial modulation (CA-GSM) method for multiple-input multiple-output (MIMO) visible light communication (VLC) systems with quadrichromatic LEDs (QLEDs).

Lines in supersingular quartics
We show that the number of lines contained in a supersingular quartic surface is 40 or at most 32, if the characteristic of the field equals 2, and it is 112, 58, or at most 52, if the characteristic equals 3.

Small Extended Generalized Quadrangles
An extended generalized quadrangle (EGQ) is a connected point-block incidence structure \({\mathcal G}\) with the property that for any point P the points collinear with P (and different from P) and the blocks incident with P form a generalized quadrangle known as the (point) residue at P.

The pseudo-hyperplanes and homogeneous pseudo-embeddings of the generalized quadrangles of order (3, t) [PDF]
In the paper "as reported by De Bruyn (Adv Geom, to appear)", we introduced the notions of pseudo-hyperplane and pseudo-embedding of a point-line geometry and proved that every generalized quadrangle of order (s, t), 2 a parts per thousand currency sign ...

A Combinatorial Grassmannian Representation of the Magic Three-Qubit Veldkamp Line
It is demonstrated that the magic three-qubit Veldkamp line occurs naturally within the Veldkamp space of a combinatorial Grassmannian of type G 2 ( 7 ) , V ( G 2 ( 7 ) ) .

A spectrum result on maximal partial ovoids of the generalized quadrangle Q(4,q), q odd [PDF]
In this article, we prove a spectrum result on maximal partial ovoids of the generalized quadrangle Q(4, q), q odd, i.e. for every integer k in the interval [a, b], where a approximate to q2 and b approximate to 9/10q2, there exists a maximal partial ...

On collineations and dualities of finite generalized polygons [PDF]
In this paper we generalize a result of Benson to all finite generalized polygons. In particular, given a collineation theta of a finite generalized polygon S, we obtain a relation between the parameters of S and, for various natural numbers i, the ...

On hyperovals of polar spaces [PDF]
We derive lower and upper bounds for the size of a hyperoval of a finite polar space of rank 3. We give a computer-free proof for the uniqueness, up to isomorphism, of the hyperoval of size 126 of H(5, 4) and prove that the near hexagon E-3 has up to ...

An inequality for generalized quadrangles [PDF]
Let S \mathcal {S} be a generalized quadrangle of order (s, t). Let X and Y be disjoint sets of pairwise noncollinear points of S \mathcal {S} such that each point of X is collinear with each point of Y. If m = | X |

A power-based perspective of mechanical systems [PDF]
This paper is concerned with the construction of a power-based modeling framework for a large class of mechanical systems. Mathematically this is formalized by proving that every standard mechanical system (with or without dissipation) can be written as ...
