A strong edge coloring of a graph G is proper edges in such that any two distance at most 2 are colored with distinct colors. The chromatic index χs′(G) the smallest integer l admits using K4(t)-minor free does not contain K4(t) as contraction subgraph, where obtained from K4 by subdividing exactly t−4 times. paper shows every maximum degree Δ(G) has χs′(G)≤(t−1)Δ(G) for t∈{5,6,7} which general...

introduction: foreign body aspiration (fba) represents a life-threatening emergency .it occurs primarily in children below 3 years. generally, the most common aspirated fb is organic material such as nuts or beans. sharp foreign bodies (fbs) are of particular concern to the attending clinician, because of their potential to perforate the air passage and cause possible complications. here in, we...

The quality of case data can be an important factor for a Case Based Reasoning (CBR) system. In our research, we are facing a diagnostic problem in a product maintenance domain, where a large volume of low quality case data is collected. In this paper, we report an experimental study of whether using domain knowledge can improve the performance of either non-diversified or diversified retrieval...

In parameterized complexity each problem instance comes with a parameter k, and a parameterized problem is said to admit a polynomial kernel if there are polynomial time preprocessing rules that reduce the input instance to an instance with size polynomial in k. Many problems have been shown to admit polynomial kernels, but it is only recently that a framework for showing the non-existence of p...

We consider the Einstein-dust equations with positive cosmological constant λ on manifolds with time slices diffeomorphic to an orientable, compact 3-manifold S. It is shown that the set of standard Cauchy data for the Einstein-λ-dust equations on S contains an open (in terms of suitable Sobolev norms) subset of data that develop into solutions which admit at future time-like infinity a space-l...
