Collineation groups of translation planes of small dimension
International Journal of Mathematics and Mathematical Sciences, 1981 A subgroup of the linear translation complement of a translation plane is geometrically irreducible if it has no invariant lines or subplanes. A similar definition can be given for geometrically primitive.

On the equivalence of linear sets
, 2015 Let $L$ be a linear set of pseudoregulus type in a line $\ell$ in $\Sigma^*=\mathrm{PG}(t-1,q^t)$, $t=5$ or $t>6$. We provide examples of $q$-order canonical subgeometries $\Sigma_1,\, \Sigma_2 \subset \Sigma^*$ such that there is a $(t-3)$-space $\Gamma

On collineation groups of translation planes of order q4
International Journal of Mathematics and Mathematical Sciences, 1986 Let P be an affine translation plane of order q4 admitting a nonsolvable group G in its translation complement. If G fixes more than q+1 slopes, the structure of G is determined.

Multistable Soft Robots Assembled from Bistable Auxetic Building Blocks
Advanced Intelligent Systems, Volume 7, Issue 4, April 2025.Bistable and multistable structures offer solutions for enhancing shape retention and load capacity in soft robots. This study presents a multistable soft robot design using bistable auxetic building blocks. Illustrated through a manipulator with 216 discrete stable states and a tube‐crawling robot, the design demonstrates significant versatility and ...

International Journal of Mathematics and Mathematical Sciences, 1981 Let a finite projective plane be called rank m plane if it admits a collineation group G of rank m, let it be called strong rank m plane if moreover GP=G1 for some point-line pair (P,1).

On Quasi‐Hermitian Varieties in Even Characteristic and Related Orthogonal Arrays
Journal of Combinatorial Designs, Volume 33, Issue 3, Page 109-122, March 2025.ABSTRACT In this article, we study the BM quasi‐Hermitian varieties, laying in the three‐dimensional Desarguesian projective space of even order. After a brief investigation of their combinatorial properties, we first show that all of these varieties are projectively equivalent, exhibiting a behavior which is strikingly different from what happens in ...

On unitary collineation groups
, 1972 If II is a finite projective plane of order q2 over the field K = GF(q2), then 17 admits a polarity 6 which is induced on I7 by a nondegenerate hermitian form on the underlying vector space.

Canadian Geographer / Le géographe canadien, Volume 69, Issue 1, Spring / printemps 2025.Abstract North America is characterized by an expansive continental plain that has been described as platter‐flat. Yet this central continental plain includes isolated uplands that some people call mountains. The hill‐mountain muddle is a classic problem of geomorphology, arising from the challenge of discriminating continuous, attached forms.

Intensity gradient based edge detection for pixelated communication systems
The Journal of Engineering, Volume 2019, Issue 12, Page 8463-8470, December 2019., 2019 Pixelated optical communication systems transmit data using a series of encoded pixelated images. The decoding of these pixelated images is important for reliable data communication. This study proposes a novel intensity gradient‐based edge detection (IGED) method for the received pixelated images.
