The physical processes in the damper system of rotor with appearance a static eccentricity for two types salient-pole synchronous machines - capsule hydrogenator SGK 538/160-70M capacity 22 MW and generator 500 kW were investigated by means mathematical modeling. A field model has been developed that takes into account combined action three fields different nature: electromagnetic, temperature ...

In this paper, we calculate the eccentric connectivity index and the eccentricity sequence of two infinite classes of fullerenes with 50 + 10k and 60 + 12k (k in N) carbon atoms.

Let G be a connected graph. The eccentricity of path P, denoted by eccG(P), is the maximum distance from P to any vertex in G. In Central (CP) problem, our aim find minimum eccentricity. This problem was introduced Cockayne et al., 1981, study different centrality measures on graphs. They showed that CP can solved linear time trees, but it known NP-hard many classes graphs such as chordal bipar...

5 To be submitted to Paleoceanography. The accuracy of geologic chronologies can, in principle, be improved through 6 orbital tuning, the systematic adjustment of a chronology to bring the as-7 sociated record into greater alignment with an orbitally derived signal. It would 8 be useful to have a general test for the success of orbital tuning, and one pro-9 posal has been that eccentricity ough...

To investigate the relationship between reaction time (RT), stimulus intensity and visual field eccentricity. We generated frequency of seeing (FOS) curves and measured RTs by testing 10 perimetrically experienced normal subjects with a Humphrey perimeter controlled by a custom program. Subjects were tested from 10 degrees to 50 degrees eccentricity along the nasal horizontal meridian in 10 deg...

The aim of this paper is to compare the static and dynamic performances two types herringbone grooved journal bearings (HGJBs), that is, pumping-out HGJB pumping-in HGJB. Firstly, based on finite control volume method principle flow balance, an equivalent Reynolds equation considering turbulence effect derived. Then, motion angular displacement analyzed with linear perturbation method. lineariz...

Abstract Analogues to multiplicative Zagreb indices in this paper two new type of eccentricity related topological index are introduced called the first and second multiplicative Zagreb eccentricity indices and is defined as product of squares of the eccentricities of the vertices and product of product of the eccentricities of the adjacent vertices. In this paper we give some upper and lower b...
