Let S = (a1,. . . , am; b1, . . . , bn), where a1, . . . , am and b1, . . . , bn are two sequences of nonnegative integers. We say that S is a bigraphic pair if there exists a simple bipartite graph G with partite sets {x1, x2, . . . , xm} and {y1, y2, .

Evaluation of Infrared Detector Response Characteristics Drift Based on Time Sequence [PDF]
The response characteristic drift of infrared detector seriously degrades the imaging quality and system performance. Aiming at the lack of effective evaluation index and difficulty in modeling and evaluating the response characteristic drift of infrared

Finding the Zeros of a High-Degree Polynomial Sequence
A 1-parameter initial-boundary value problem for a linear spatially 1-dimensional homogeneous degenerate wave equation, posed in a space-time rectangle, in case of strong degeneracy, was reduced to a linear integro-differential equation of convolution ...

Multi-switch: A tool for finding potential edge-disjoint 1-factors
Let n be even, let π = (d1, ... , dn) be a graphic degree sequence, and let π - k = (d1-k, ... , dn-k) also be graphic. Kundu proved that π has a realization G containing a k-factor, or k-regular graph.

Realizing Degree Sequences in Parallel [PDF]
Summary: A sequence \(d\) of integers is a degree sequence if there exists a (simple) graph \(G\) such that the components of \(d\) are equal to the degree of the vertices of \(G\). The graph \(G\) is said to be a realization of \(d\). We provide an efficient parallel algorithm to realize \(d\); the algorithm runs in \(O(\log n)\) time using \(O(n+ m)\)

Empirical Likelihodd Methods for an AR(1) process with ARCH(1) errors [PDF]
For an AR(1) process with ARCH(1) errors, we propose empirical likelihood tests for testing whether the sequence is strictly stationary but has infinite variance, or the sequence is an ARCH(1) sequence or the sequence is an iid sequence.

Forcing $k$-Repetitions in Degree Sequences [PDF]
One of the most basic results in graph theory states that every graph with at least two vertices has two vertices with the same degree. Since there are graphs without $3$ vertices of the same degree, it is natural to ask if for any fixed $k$, every graph $G$ is "close" to a graph $G'$ with $k$ vertices of the same degree. Our main result in this paper

A Constructive Extension of the Characterization on Potentially Ks,t-Bigraphic Pairs
Let Ks,t be the complete bipartite graph with partite sets of size s and t. Let L1 = ([a1, b1], . . . , [am, bm]) and L2 = ([c1, d1], . . . , [cn, dn]) be two sequences of intervals consisting of nonnegative integers with a1 ≥ a2 ≥ . . . ≥ am and c1 ≥ c2

On balanced bipartitions of graphs
Bollobás and Scott conjectured that every graph G has a balanced bipartite spanning subgraph H such that for each for each In this paper, we consider the contrary side and show that every graphic sequence has a realization G which admits a balanced ...
