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.

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 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 ...

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 ...

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

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 Theoretical Investigation of Channel Wave Multipath Propagation in a Coal Seam
Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019 This study investigates the mechanism of channel wave multipath propagation to determine features of a channel wave in a coal seam. For this purpose, deduction formulas were used for different time delays and propagation paths and, subsequently, a multipath fading channel wave pattern was built. MATLAB software was used to simulate the model.

Automorphisms and opposition in twin buildings
, 2012 We show that every automorphism of a thick twin building interchanging the halves of the building maps some residue to an opposite one. Furthermore we show that no automorphism of a locally finite 2-spherical twin building of rank at least 3 maps every ...
