Linear Determination of a Camera's Intrinsic Parameters Using Two Intersecting Circles
International Journal of Advanced Robotic Systems, 2014 An approach using two intersecting circles is proposed as a linear approach for determining a camera's intrinsic parameters. The two intersecting coplanar circles have four intersection points in the projective plane: two real points and two circular ...

WDVV-Type Relations for Welschinger's Invariants: Applications
, 2019 We first recall Solomon's relations for Welschinger's invariants counting real curves in real symplectic fourfolds, announced in \cite{Jake2} and established in \cite{RealWDVV}, and the WDVV-style relations for Welschinger's invariants counting real ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose The aim of this study was to investigate the influence of the simultaneous multislice acceleration (SMS) technique as well as two‐dimensional (2D) and three‐dimensional (3D) tumor segmentations on radiomics features (RFs) within the parametric maps of cervical cancer, which were computed by intravoxel incoherent motion (IVIM) and ...

ScienceOpen Research, 2014 The projective representation of groups was introduced in 1904 by Issai Schur. It differs from the normal representation of groups by a twisting factor, which we call Schur function in this book and which is called sometimes normalized factor set in the ...

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose The study evaluates rapid linear accelerator (Linac) single isocenter stereotactic radiosurgery (SRS) with Hyperarc for large target numbers. We compared to Gamma Knife (GK), which suffers from long treatment times and investigated causes of differences. Methods Linac SRS and GK treatment plans for patients receiving 18 Gy to the gross

The cohomology ring away from 2 of configuration spaces on real projective spaces [PDF]
arXiv, 2015 Let R be a commutative ring containing 1/2. We compute the R-cohomology ring of the configuration space F(m,k) of k ordered points in the m-dimensional real projective space. The method uses the observation that the orbit configuration space of k ordered points in the m-dimensional sphere (with respect to the antipodal action) is a 2^k-fold covering of

The algebraic transfer for the real projective space
Comptes Rendus. Mathématique, 2019 Abstract A chain-level representation of the Singer transfer for any left A -module is constructed. We prove that the image of the Singer transfer Tr ⁎ R P ∞ for the infinite real projective space is a module over the image of the transfer Tr ⁎ for the sphere.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Current radiotherapy practices rely on manual contouring of CT scans, which is time‐consuming, prone to variability, and requires highly trained experts. There is a need for more efficient and consistent contouring methods. This study evaluated the performance of the Varian Ethos AI auto‐contouring tool to assess its potential integration into

Holomorphic projection and duality for domains in complex projective space [PDF]
arXiv, 2008 We show that the efficiency of a natural pairing between certain projectively invariant Hardy spaces on dual strongly C-linearly convex real hypersurfaces in complex projective space is measured by the norm of the corresponding Leray transform.
