Alpha-invariant of Toric Line Bundles [PDF]
Annales Polonici Mathematici, 2015 We generalize the work of Jian Song to compute the alpha invariant of any (nef and big) toric line bundle in terms of the associated polytope. We use the analytic version of the computation of the log canonical threshold of monomial ideals to give the ...

A topological invariant of line arrangements [PDF]
ANNALI SCUOLA NORMALE SUPERIORE - CLASSE DI SCIENZE, 2014 We define a new topological invariant of line arrangements in the complex projective plane. This invariant is a root of unity defined under some combinatorial restrictions for arrangements endowed with some special torsion character on the fundamental ...

World-line Quantisation of a Reciprocally Invariant System [PDF]
Journal of Physics A: Mathematical and Theoretical, 2007 We present the world-line quantisation of a system invariant under the symmetries of reciprocal relativity (pseudo-unitary transformations on ``phase space coordinates" $(x^\mu(\tau),p^\mu(\tau))$ which preserve the Minkowski metric and the symplectic ...

Development of a multi-channel classifier of rail line states [PDF]
E3S Web of Conferences, 2023 The article deals with the construction of a three-channel invariant classifier that has the properties of classifying the states of rail lines into a set of classes that are invariant to changes in the longitudinal resistance of the rail line and the ...

Evaluation of the Noise Immunity of the MIAM Communication System
Proceedings of the International Conference on Applied Innovations in IT, 2021 The article proposes a modification of the known invariant amplitude modulation that transmits the values of information elements by the ratio of the lengths of the signal vectors lying on a straight line passing through the origin of the coordinate ...

Electronic Journal of Qualitative Theory of Differential Equations, 2023 In this article we consider the class $\textbf{CSL}_7^{2r2c \infty}$ of non-degenerate real planar cubic vector fields, which possess two real and two complex distinct infinite singularities and invariant straight lines of total multiplicity 7, including

A Multi-Feature Fusion Slam System Attaching Semantic Invariant to Points and Lines
Sensors, 2021 The traditional simultaneous localization and mapping (SLAM) system uses static points of the environment as features for real-time localization and mapping. When there are few available point features, the system is difficult to implement.

Two-Particle Scattering on Non-Translation Invariant Line Lattices [PDF]
QuantumQuantum walks have been used to develop quantum algorithms since their inception, and can be seen as an alternative to the usual circuit model; combining single-particle quantum walks on sparse graphs with two-particle scattering on a line lattice is ...

Off-Line Arabic Signature Recognition Based on Invariant Moments Properties [PDF]
Engineering and Technology Journal, 2011 In this paper, a number of persons were selected to use their signature as a database for the work. Six signatures were taken from each person through two separated period of time using the same pen and paper.

Point-to-line last passage percolation and the invariant measure of a system of reflecting Brownian motions [PDF]
, 2019 This paper proves an equality in law between the invariant measure of a reflected system of Brownian motions and a vector of point-to-line last passage percolation times in a discrete random environment.
