On collineation groups of translation planes of order q4
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.

Collineation varieties of tensors [PDF]
In this article, we introduce the $k$-th collineation variety of a third order tensor. This is the closure of the image of the rational map of size $k$ minors of a matrix of linear forms associated to the tensor. We classify such varieties in the case of

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).

Finding the Collineation Between two Projective Reconstructions
The problem of finding the collineation between two 3-D projective reconstructions has been proved to be useful for a variety of tasks such as calibration of a stereo rig and 3-D affine and/or Euclidean reconstruction.

Incremental Localization Algorithm Based on Regularized Iteratively Reweighted Least Square
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 ...

Ovoids of PG(3,q) stabilized by a central collineation
In this paper we give a short proof that an ovoid of PG(3,q) is stabilized by a non-trivial central collineation of PG(3,q) if and only if it is an elliptic quadric. © 2003 Elsevier Science Ltd.

A Co-Point Mapping-Based Approach to Drivable Area Detection for Self-Driving Cars
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

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

Riemann Solitons and Ricci Bi-Conformal Vector Fields on 4-Dimensional Oscillator Group
We consider Riemann soliton vector fields and Ricci bi-conformal vector fields on the oscillator group. We prove that the oscillator group admits Riemann solitons. Subsequently, we provide a complete classification of all Ricci bi-conformal vector fields
