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).

Collineation groups strongly irreducible on an oval in a projective plane of odd order
, 2015 Strongly irreducibile collineation groups have played an important role in the study of collineation groups of a finite projective plane. The theory of strongly irreducible collineation groups containing perspectivities is well developed, but not many ...

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.

Incremental Localization Algorithm Based on Regularized Iteratively Reweighted Least Square
Foundations of Computing and Decision Sciences, 2016 Incremental localization algorithm is a distributed localization method with excellent characteristics for wireless network. However, its estimated result is generally influenced by the heteroscedasticity arising from cumulative errors and the ...

2‐Conformal Vector Fields on the Model Sol Space and Hyperbolic Ricci Solitons
Journal of Mathematics, Volume 2025, Issue 1, 2025.In this study, we present the notion of 2‐conformal vector fields on Riemannian and semi‐Riemannian manifolds, which are an extension of Killing and conformal vector fields. Next, we provide suitable vector fields in Sol space that are 2‐conformal. A few implications of 2‐conformal vector fields in hyperbolic Ricci solitons are investigated.

A Co-Point Mapping-Based Approach to Drivable Area Detection for Self-Driving Cars
Engineering, 2018 The randomness and complexity of urban traffic scenes make it a difficult task for self-driving cars to detect drivable areas. Inspired by human driving behaviors, we propose a novel method of drivable area detection for self-driving cars based on fusing

British Journal of Plastic Surgery, 1950 Summary Two cases of Treacher Collins syndrome are reported. The family history is shown to be variable, but there appears to be a distinct familial incidence. A comparison has been drawn between the Treacher Collins syndrome and unilateral facial agenesis. The embryology is discussed, and it has been suggested that the causative factor may influence

On the system of fixed points of a collineation in noncommutative projective geometry [PDF]
, 2002 Noncommutativity of the ground field has a deep influence on the geometry of projective spaces, as shown, for instance, by the failure of Pappus’ theorem.
