Subclasses of Normal Helly Circular-Arc Graphs [PDF]
, 2011 A Helly circular-arc model M = (C,A) is a circle C together with a Helly family \A of arcs of C. If no arc is contained in any other, then M is a proper Helly circular-arc model, if every arc has the same length, then M is a unit Helly circular-arc model,

New Arcs in PG(3,8) by Singer Group
Al-Mustansiriyah Journal of Science, 2022 In this paper, studied the types of (k, r)-arcs were constructed by action of groups on the three-dimensional projective space over the Galois field of order eight. Also, determined if they form complete arcs or not.

VERIFICATION OF THE DIFFUSION AND TRANSPORT SOLVERS WITHIN DIF3D FOR 3D HEXAGONAL GEOMETRIES [PDF]
EPJ Web of Conferences, 2021 The DIF3D code (DIFfusion 3D) has been a workhorse of fast reactor analysis work at Argonne National Laboratory for over 40 years. DIF3D was primarily built in the late 1970s as a three-dimensional multigroup diffusion equation solver operating on semi ...

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 ...

Testing of multidimensional tectonomagmatic discrimination diagrams on fresh and altered rocks
Geologica Carpathica, 2016 We evaluated 55 multidimensional diagrams proposed during 2004-2013 for the tectonic discrimination of ultrabasic, basic, intermediate, and acid magmas.

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.

Influence of System Parameters on Fuse Protection Use in Regenerative DC Drives
Energies, 2009 Current limiting fuses are widely used to protect the thyristors in DC drive systems. One very important problem is the choice of the correct voltage rating for fuses protecting regenerative DC drives, where many types of fault may occur, which makes ...
