The oscillation period for moored vessels in Constanţa port
"... The present paper brings to attention the importance of the lines used to anchor the vessels in harbours. For the moored vessels, oscillation is one of the most important parameters. The elastic behaviour of the cables, made of various fibers, is difficult to determine, because it depends on materia ..."

on material, composition, loading history and environmental conditions. The natural oscillation period of the moored vessel depends on the vessels displacement, number, type and loading of the lines. Several cases were studied, in order to determine the influence of the variables on the oscillation
Spectral Oscillations, Periodic Orbits, and Scaling
, 2000
"... The eigenvalue density of a quantummechanical system exhibits oscillations, determined by the closed orbits of the corresponding classical system; this relationship is simple and strong for waves in billiards or on manifolds, but becomes slightly muddy for a Schrodinger equation with a potential, w ..."

, where the orbits depend on the energy. We discuss several variants of a way to restore the simplicity by rescaling the coupling constant or the size of the orbit or both. In each case the relation between the oscillation frequency and the period of the orbit is inspected critically; in many cases

Climate and atmospheric history of the past 420,000 years from the Vostok ice core,
 Antarctica. Nature
, 1999
"... Antarctica has allowed the extension of the ice record of atmospheric composition and climate to the past four glacialinterglacial cycles. The succession of changes through each climate cycle and termination was similar, and atmospheric and climate properties oscillated between stable bounds. Inte ..."

HOMOGENIZATION AND TWOSCALE CONVERGENCE
, 1992
"... Following an idea of G. Nguetseng, the author defines a notion of "twoscale" convergence, which is aimed at a better description of sequences of oscillating functions. Bounded sequences in L2(f) are proven to be relatively compact with respect to this new type of convergence. A corrector ..."

type theorem (i.e., which permits, in some cases, replacing a sequence by its "twoscale " limit, up to a strongly convergent remainder in L2(12)) is also established. These results are especially useful for the homogenization of partial differential equations with periodically oscillating

The Exact Distribution of the Oscillation Period in the Underdamped One Dimensional Sinai Model
, 2001
"... Abstract: We consider the Newtonian dynamics of a massive particle in a one dimemsional random potential which is a Brownian motion in space. This is the zero temperature nondamped Sinai model. As there is no dissipation the particle oscillates between two turning points where its kinetic energy bec ..."

becomes zero. The period of oscillation is a random variable fluctuating from sample to sample of the random potential. We compute the probability distribution of this period exactly and show that it has a power law tail for large period, P(T) ∼ T −5/3 and an essential singluarity P(T) ∼ exp(−1/T
INSTABILITY OF RAPIDLYOSCILLATING PERIODIC SOLUTIONS FOR DISCONTINUOUS DIFFERENTIAL DELAY EQUATIONS
"... Abstract. We study the equation (⋆) ˙x(t) =−h(x(t − 1)) + f(x(t)) for t ≥ 0, x  = x0, [−1,0] where h is an odd function defined by h(y) is equal to a if 0 <y<c, equal to b if y ≥ c, a>b>0 and c>0 and f is an odd C 1 function such that sup f(x)  <b. We first consider the equatio ..."

the equation ˙x(t) =−h(x(t − 1)), corresponding to f ≡ 0. We find the admissible shapes of rapidlyoscillating symmetric periodic solutions and we show that these periodic solutions are all unstable. We then extend these results to our general equation (⋆). 1.
