A Controlled Language for Semantic Annotation and Interoperability in e-Business Applications

In this paper we present the basic ideas underlying a solution for software application interoperability in a business context. Key elements of our solution are a Reference Ontology, aimed at modelling the key aspects of a business domain, and a Semantic Annotation Language, SMAIL, used to associate semantic expressions, defined in terms of the reference ontology, to business elements

L'età del ferro a Bisignano

Analisi del contesto di necropoli di Bisignano (CS), risalente al primo Ferro e proveniente sia da rinvenimenti sporadici, sia da scavi di emergenza; discussione della struttra insediativa nella media valle del Crati

Monte Cimino (Soriano nel Cimino, VT). Un centro fortificato e un complesso cultuale dell'età del bronzo finale. Rapporto preliminare.

Il contributo illustra i risultati degli scavi condotti da l 2009 al 2011 nell'insediamento del Monte Cimino in Etruria meridionale. Le evidenze mostrano la presenza di mura imponenti di fortificazione e di un'area di culto monumentale databile alla fine del Bronzo finale

Efficient fiber to waveguide coupling by a lens on the end of the optical fiber fabricated by Focus Ion Beam Milling

The purpose of this work is to demonstrate efficient optical coupling between a single, mode fiber (SMF) and a waveguide (LiNbO3-APE) using a micro-lens fabricated directly on the cleaved end of a fiber using a focused ion beam (FIB) milling process. The design, micro-fabrication and testing of diffractive optical elements (DOEs) with continuous relief fabricated on the tip of a single mode optical fiber are discussed in detail. A 30 keV focused Ga+ ion beam is used to mill a continuous relief microstructure; DOEs with diameters as small as 15 μm were fabricated. The design of the DOE-lens and the calculations related to the optical fiber-to-waveguide coupling were carried out using our own developed code. The profile of the fabricated lens was very well reproduced in ten levels each 100 nm thick. This fabricated DOE-lens was able to focus the Gaussian beam from the fiber, into a waveguide plane at a distance of 28 μm from the lens surface. The diameter of the beam leaving the fiber was of about 10.5 μm while the size of the focused waist was 5.2 μm. This led to efficient matching of the fundamental mode of the fiber to that of waveguide. We have also measured the coupling efficiency using a laser beam at 1550 nm wavelength. The optical coupling using the lens on the fiber end is 67% more efficient than with direct coupling between the fiber and the waveguide. © 2004 Elsevier B.V. All rights reserved
