Active mode-locking of a neodymium-doped fiber laser using intra-cavity pulse compression
No full textActive mode locking of a Nd3+doped fiber laser with piezoelectrically induced Raman-Nath diffraction modulation ie demonstrated. By using intracavity pulse compression, stable pulses of 2.4-psec length are generated at a wavelength of 1054 nm
M.E. Church exterior
No full textA monochrome postcard of the M.E. Church in Georgetown, Delaware. The church was made out of brick and had a tall tower on its corner. Writing on the right indicates that the author was having a good time. Mrs. P. H. Adkins of Milton, Delaware, received this postcard. A postmark on the back indicates that this postcard was mailed from Georgetown, Delaware. The postage stamp is a one-cent U.S. #300, Benjamin Franklin. The back of the postcard is labeled 75.00 and 0240

Cladding-pumped passive harmonically mode-locked fiber laser
No full textA passive harmonically mode-locked fiber laser cladding pumped by a broad-area diode-laser array is described. Harmonic mode locking is obtained in a frequency range from 33.3 to 128.6 MHz, where the higher frequency limit is imposed because of insufficient available pump power. The maximum pulse jitter in one cavity round-trip time is between 300 and 50ps in the whole frequency range, and the sidebands in the frequency domain are suppressed by as much as 50dB. 600-fs bandwidth-limited pulses with pulse energies of as much as 20pJ are obtained, giving rise to an average output power as great as 2.5m
On using Directional Information for Parameter Space Decomposition in Ellipse Detection
No full textIn this paper we use the parametric polar representation to extend the application of edge directional information from circle to ellipse extraction. As a result we obtain a mapping which decomposes the parameter space required for ellipse extraction into two independent sub-spaces and one final histogram accumulator. The mapping includes the tangent of the angle of the first and second directional derivatives. These tangents are computed by considering edge direction at two border points. We show that the use of gradient information for parameter space decomposition avoids the intensive point labelling imposed by geometric constraints used by other approaches
La fecondazione assistita dopo dieci anni di legge 40 : il punto di vista del costituzionalista
No full textThe Author of this paper adds the point of view of the constitutionalist to the debate on the Italian statute n.40/1994 on assisted reproduction illustrated by Flamigni and Mori in their work. The paper ends with a reflection on the recent decision n. 162/2014 issued by the Constitutional Court, which has declared the illegitimacy of the prohibition of heterologous reproduction
L'approvazione della legge Cirinnà : fra riconoscimento dei diritti e scontro ideologico
No full textThe New Italian Law on Civil Unions: Between Rights Recognition and Ideological Clash Abstract: The author examines the coming into force of the first Italian law on civil unions, which, for the first time, grants protection for both homosexual and different sex couples
La Corte costituzionale chiude la porta agli scienziati in nome della dignità dell’embrione
No full textThis essay aims to analize decision no. 84 of 2016 of the Italian Constitu-tional Court, on the matter of scientific research on embryos.
In particular the essay dwells with the problematic acknowledgement of the embryo dignity. The Author considers this aspect in the context of the relation between sci-entific evolution and legislative discretionality, taking into account the other deci-sions of the Court on the matter of medically assisted procreation
Penetration of fastener projectiles into construction materials
No full textThe normal impact, penetration of both projectile and fastener into soils, rocks, and concrete at low velocities has been investigated using theoretical, experimental, and numerical approaches under axisymmetric conditions. The projectile penetration theory is developed on the basis of the existing cylindrical cavity expansion theory with target materials approximated by compressible locking behaviour in a hydrostatic state and elastic-plastic, linear strain- hardening behaviour in a shear state. This theory is one-dimensional with respect to wave propagation in a radial direction. Impact penetration experiments have been performed using a cartridge-operated tool firing the steel fasteners into sandstone and concrete targets. The associated pull-out problem has also been studied. Damage to both fastener and target caused by the impact penetration is assessed using an optical microscope. Finite element programs have been employed to investigate the penetration process of the projectile, and eventually to simulate the process of fastener penetration. The dependency of the penetration process on impact velocity, projectile nose shape, projectile-target interfacial friction, and target material properties have been studied for a variety of impact conditions. Comparisons of results obtained from all three approaches are made for cases in which data are available. Agreements reached are reasonably good
