As a strengthening of the concept global forcing number graph G, complete G is cardinality minimum edge subset to which restriction every perfect matching M set M. Xu et al. (J Comb Opt 29: 803–814, 2015) revealed that also antifores each matching, and obtained for catacondensed hexagonal system, equal Clar plus hexagons (Chan MATCH Commun Math Comput Chem 74: 201–216, 2015). In this paper, we ...

We propose a model order reduction approach for non-intrusive surrogate modeling of parametric dynamical systems. The reduced over the whole parameter space is built by combining surrogates in frequency only, at few selected values parameters. This, particular, requires matching respective poles solving an optimization problem. If are constructed suitable rational interpolation strategy, and pa...

many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...

In the random geometric graph G(n,rn), n vertices are placed randomly in Euclidean d-space and edges added between any pair of distant at most rn from each other. We establish strong laws large numbers (LLNs) for a class parameters, evaluated G(n,rn) thermodynamic limit with nrnd= const., also dense nrnd→∞, rn→0. Examples include domination number, independence clique-covering eternal number tr...

acquiring up-to-date information about stands is necessary for scientific management and planning of forest. remote sensing by its great capabilities in this way can be very useful. this study was done to investigate the capability of satellite data for gathering information about beech diameter specification. 21 plots of one hectare dimension were selected at experimental forest of kheyroud in...

The aim of this study was to further explore the relationship between vocational interests and intelligence. There is some evidence in literature on the stable relationships between vocational interests and intelligence (cf. Ackerman & Heggestad, 1997). It should be noted that the majority of the previous studies have only used questionnaires for the assessment of vocational interests. Thus, it...

Mobile P2P environments are emerging as a result of rapid expansion of portable terminals that are able to establish direct wireless communication links among themselves. These kinds of terminals are under the control of persons and allowing interactions between their terminals is subject to trust between the individuals and their desire to preserve and exhibit various aspects of autonomy again...

Decision making by policymakers, public health professionals, and health care providers is often guided by the extent to which individuals feel at risk for certain adverse health events. Such health risk perceptions can be assessed in surveys using different types of probability rating scales. It has recently been suggested that rating scales that offer decomposed numeric values at the lower en...

In this study, we demonstrate the use of natural language processing methods to extract, from nanomedicine literature, numeric values of biomedical property terms of poly(amidoamine) dendrimers. We have developed a method for extracting these values for properties taken from the NanoParticle Ontology, using the General Architecture for Text Engineering and a Nearly-New Information Extraction Sy...

A special case of metric-affine gauge theory of gravity (MAG) is equivalent to general relativity with Proca matter as source. We study in detail a corresponding numeric solution of the Reissner-Nordström type. It is static, spherically symmetric, and of electric type. In particular, this solution has no horizon, so it has a naked singularity as its origin.
