Properties of the Giant Dipole Resonance in nuclei far off stability provide information on the isospin dependence of the effective nuclear interaction [1]. Moreover, recent RPA calculations of the dipole strenght in n-rich nuclei predict the existence of a new mode of collective excitation, exhausting a considerable fraction of the sum rule strenght [2, 3]. This so called Pygmy resonance, expe...

This paper is devoted to the problem of rejecting oscillatory position-dependent disturbances with unknown frequency and unknown amplitude. The considered disturbances are here assumed to be produced by eccentricity in mechanical systems and drives. Most of the previous works on eccentricity cancellation assume a time-depending oscillation, we instead assume that the oscillatory disturbance is ...

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.

The eccentricity of a node in a graph is defined as the length of a longest shortest path starting at that node. The eccentricity distribution over all nodes is a relevant descriptive property of the graph, and its extreme values allow the derivation of measures such as the radius, diameter, center and periphery of the graph. This paper describes two new methods for computing the eccentricity d...

The eccentricity distribution of exoplanets is known from radial velocity surveys to be divergent from circular orbits beyond 0.1 au. This is particularly the case for large planets where the radial velocity technique is most sensitive. The eccentricity of planetary orbits can have a large effect on the transit probability and subsequently the planet yield of transit surveys. The Kepler mission...
