BUILDING SCOUTING ACHIEVEMENT SYSTEM (Potentials and Obstacles)

The purpose of this research is to rising up a scouting achievement system that coming from potentials and obstacles at SMA N 1 Sukoharjo and SMA N 1 Wonogiri which both of them have a really good achievement at scouting competition. The system that coming up from this research very helpful for human resource management especialy on developing organizational system for educational level. This research using qualitative method which the collective data method using interview, self-conduct observation, life history, personal experience, documents and important note deeply for certain period of time to get further information about scouting achievement system from it potentials and obstacles. This research object are schools which have achievement in scouting there are SMA N 1 Sukoharjo and SMA N 1 Wonogiri. Come after the informant for this research are scout master, scout leader, and alumni who still active for helping on scouting activities on each school. The result indicates gradually a scouting achievement system must have a good organization system and training and education system. Organization system component are recruitment and member positioning, financial and facilities management, followed by having a good relationship within scouting member in or out school. Training and education system component are routine training, leadership, competition preparation exercise followed by team competition development

Distribution of the delay time and the dwell time for wave reflection from a long random potential

We re-examine and correct an earlier derivation of the distribution of the Wigner phase delay time for wave reflection from a long one-dimensional disordered conductor treated in the continuum limit. We then numerically compare the distributions of the Wigner phase delay time and the dwell time, the latter being obtained by the use of an infinitesimal imaginary potential as a clock, and investigate the effects of strong disorder and a periodic (discrete) lattice background. We find that the two distributions coincide even for strong disorder, but only for energies well away from the band-edges.Comment: Final version with minor corrections in text, 4 pages, 2 PS figure

LDPC Codes Which Can Correct Three Errors Under Iterative Decoding

In this paper, we provide necessary and sufficient conditions for a column-weight-three LDPC code to correct three errors when decoded using Gallager A algorithm. We then provide a construction technique which results in a code satisfying the above conditions. We also provide numerical assessment of code performance via simulation results.Comment: 5 pages, 3 figures, submitted to IEEE Information Theory Workshop (ITW), 200

Resonant enhancement of Raman scattering in metamaterials with hybrid electromagnetic and plasmonic resonances

A tri-layer metamaterial perfect absorber of light, consisting of (Al/ZnS/Al) films with the top aluminium layer patterned as an array of circular disk nanoantennas, is investigated for resonantly enhancing Raman scattering from C-60 fullerene molecules deposited on the metamaterial. The metamaterial is designed to have resonant bands due to plasmonic and electromagnetic resonances at the Raman pump frequency (725 nm) as well as Stokes emission bands. The Raman scattering from C60 on the metamaterial with resonantly matched bands is measured to be enhanced by an order of magnitude more than from C60 on metamaterials with off-resonant absorption bands peaked at 1090 nm. The Raman pump is significantly enhanced due to the resonance with a propagating surface plasmon band, while the highly impedance matched electromagnetic resonance is expected to couple out the Raman emission efficiently. The nature and hybridization of the plasmonic and electromagnetic resonances to form compound resonances are investigated by numerical simulations.Comment: 9 pages, 4 figure

Diffusion at constant speed in a model phase space

We reconsider the problem of diffusion of particles at constant speed and present a generalization of the Telegrapher process to higher dimensional stochastic media ($d>1$), where the particle can move along $2^d$ directions. We derive the equations for the probability density function using the ``formulae of differentiation'' of Shapiro and Loginov. The model is an advancement over similiar models of photon migration in multiply scattering media in that it results in a true diffusion at constant speed in the limit of large dimensions.Comment: Final corrected version RevTeX, 6 pages, 1 figur
