Abstract. In order to improve the steady output of micrgripper, the giant magnetostrictive micrgripper with flexure hinge is taken as the research object . Its structure and working principle are presented .the static performance experiments are done and the better linear work domain is found. On the basis of that the dynamic model of the microgripper is established and the formula of the micro...

– The multipole expansion technique is applied to one of the largest magnetic molecules, Fe30. The molecule’s dipole, toroid and quadrupole magnetic moments are equal to zero (in the absence of magnetic field) so the multipole expansion starts from the octopole moment. Probably the Fe30 molecule is the most symmetrical magnetic body synthesized so far. The magnetization process is considered th...

We consider classical string spectrum of Rt× CP, and construct a family of solutions with residual SU(2) symmetry by the dressing method on SU(4)/U(3) sigma model. All of them obey the square-root type dispersion relation, as is expected from the psu(2|2) symmetry. A single dyonic giant magnon is not found in this approach. [email protected]

Expected Bequests and their Distribution Michael D. Hurd and James P. Smith Based on a sample of actual bequests that is population-representative and on the subjective probability of bequests, we estimate the distribution of bequests that the older population will make. We find that the distribution is highly skewed, so that the typical baby-boom person will receive a very modest inheritance. ...

Using a microscopic 1 p a r t i c l e 1 hole doorway model fo r nuclear exci ted states we show that the continuous forward angle energy spectra of medium energy (p .n) react ions are mainly a resu l t of d i rec t one-step processes. The model is appl ied to the reactions Ca(p,n) at 160 MeV and to 9 0 Zr (p ,n ) at 200 MeV incident energy. In case of 9 0 Zr (p ,n ) we f i nd that a large f r a...

Big-step semantics for languages with abrupt termination and/or divergence suffer from a serious duplication problem, addressed by the novel ‘pretty-big-step’ style presented by Charguéraud at ESOP’13. Such rules are less concise than corresponding small-step rules, but they have the same advantages as big-step rules for program correctness proofs. Here, we show how to automatically derive pret...

The observed mass function for all known extrasolar giant planets (EGPs) varies approximately as M −1 for mass M between ∼ 0.2 Jupiter masses (M J) and ∼ 5 M J. In order to study evaporation effects for highly-irradiated EGPs in this mass range, we have constructed an observational mass function for a subset of EGPs in the same mass range but with orbital radii < 0.07 AU. Surprisingly, the mass...

Assume submodels are in exponential family: pm(x, z; θm) = exp { θ m ( φm(x)φ Z(z) ) −Am(θm) } for x ∈ X , z ∈ Zm and 0 otherwise Reformulation of Product EM: Aggregate parameters: b = ∑ m bm, bm = φ X m(x) θm E-step: compute expected sufficient statistics μ = E(b,∩mZm) def = Eq(z;b)φ(z) with support ∩mZm M-step: set θm to match moments φ X m(x)μ Exponential family formulation Two sources of in...

Understanding finite-size effects is one of the key open questions in solving planar AdS/CFT. In this paper we discuss these effects in the AdS5×S string theory at one-loop in the world-sheet coupling. First we provide a very general, efficient way to compute the fluctuation frequencies, which allows to determine the energy shift for very general multi-cut solutions. Then we apply this to two-c...

Optimal firm size and patterns of returns to scale among the local exchange companies in the U.S. telecommunications industry are estimated for the years: 1975, 1978, 1981, 1984, 1987 and 1990. The independent companies display increasing returns to scale, while the Baby Bells display constant or decreasing returns to scale. The independent companies operate at a scale smaller than optimal size...
