In this paper a schema of graphical parameters is proposed. Based on the parameter integrity introduced by Barefoot, Entringer and Swart, members Ψ(G) of this schema have the general form Ψ(G) = min{ |S| + ψ(G − S) : S ⊂ V (G) }, where ψ(G) is another given graphical parameter. Examples include integrity, mean integrity, connectivity and vertex cover number. General results and bounds for the s...

We show that there exists a Martin-Löf random degree which has a strong minimal cover.

Flight testing of aircraft in which new design concepts, problems, and deficiencies are examined, involves the collection of a large quantity of data or test parameters allocated onto blocks within a telemetry frame or Data Cycle Map (DCM). Individual parameters are sampled at different rates and may vary in both their word length and the number of words used to represent them. During a flight ...

In the Set Cover problem, the input is a ground set of n elements and a collection of m sets, and the goal is to find the smallest sub-collection of sets whose union is the entire ground set. The fastest algorithm known runs in time O(mn2) [Fomin et al., WG 2004], and the Set Cover Conjecture (SeCoCo) [Cygan et al., TALG 2016] asserts that for every fixed ε > 0, no algorithm can solve Set Cover...

This paper attempts to introduce readers with the concept and methodology of bootstrap in Statist ics, which is placed under a larger umbrella of resampling. Major port ion of the discussions should be accessible to any one who has had a couple of college level applied stat istics courses. Towards the end, we attempt to provide glimpses of the vast l i terature published on the topic, which sho...

Live scleractinian corals are a prime microhabitat for many recruiting coral reef fishes, yet live coral cover has exhibited widespread declines, and the impact of this loss on recruiting fishes is not well understood. Although reduced recruitment rates of parrotfishes (Scaridae) have been observed after loss of coral cover, increased juvenile parrotfish abundance observed in connection with in...

Different landscape elements, including archaeological remains, can be automatically classified when their spectral characteristics are different, but major difficulties occur when extracting and classifying archaeological spectral features, as archaeological remains do not have unique shape or spectral characteristics. The spectral anomaly characteristics due to buried remains depend strongly ...

modern computerized technology enables more complex visual stimuli and test procedures to be in-corporated into conventional perimetry resulting in several developments in automated perimetry that have contributed to more efficient diagnosis and management of eye diseases. this review will cover a number of advances in automated perimetry including frequency doubling technology perimetry, short...

Protein crystallization screens frequently yield salt crystals as well as protein crystals. A simple method for determining whether a crystal is composed of salt or macromolecules is suggested. A drop containing one or more crystals is transferred to a glass cover slip and the cover slip is then passed through the flame of a Bunsen burner. Macromolecule crystals are destroyed by this treatment,...
