, 2019 In this paper, we study KM-arcs in PG(2, q), the Desarguesian projective plane of order q. A KM-arc A of type t is a natural generalisation of a hyperoval: it is a set of q+t points in PG(2, q) such that every line of PG(2, q) meets A in 0, 2 or t points.

Interhemispheric Conjugacy of Multiple Transpolar Arcs
Geophysical Research Letters, 2023 Multiple transpolar arcs appearing simultaneously in the polar cap have gained much interest in recent years. By analyzing Defense Meteorological Satellite Program Special Sensor Ultraviolet Spectrographic Imagers data, we report for the first time, that

A complete (48, 4)-arc in the Projective Plane Over the Field of Order Seventeen
مجلة بغداد للعلوم, 2021 The article describes a certain computation method of -arcs to construct the number of distinct -arcs in for . In this method, a new approach employed to compute the number of -arcs and the number of distinct arcs respectively. This approach is based on

Discrete Mathematics, 1994 In \(\text{PG}(n,q)\), a \(k\)-arc is a set of \(k\) points such that \(k\geq n+1\) but not \(n+1\) points belong to a hyperplane. A normal rational curve in \(\text{PG}(n,q)\), \(2\leq n\leq q-2\) is a \(q+1\) arc projectively equivalent to the set of points \(\{(1,t, \cdots, t^ n)\mid t\in \text{GF} (q)^ +\}\) where \(\text{GF}(q)^ +\) denotes ...

Arc-consistency and arc-consistency again [PDF]
Artificial Intelligence, 1994 There is no need to show the importance of arc-consistency in Constraint Networks. Mohr and Henderson [9] have proposed AC-4, an algorithm with optimal worst-case time complexity. But it has two drawbacks: its space complexity and average time complexity.

ARC Detection in DC ARC Furnaces [PDF]
, 2014 A direct-current (DC) plasma arc furnace is a type of electric furnace used for metallurgical operations. The successful operation of DC furnaces depends to a large extent on gaining a fundamental understanding of the arc phenomenon itself, and ensuring its presence in the furnace at all times.

Existence Of (47,5)- Arcs in The Projective Plane PG (2,13) [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2004 In this work we show the existence of complete (47,5)- arcs which are unknown until now. The upper bound for the (k,5)- arcs is narrowed in the finite projective plane PG (2,13). The narrowing is fulfilled by finding complete (47,5)-arcs which are 372
