Error estimates of Gaussian-type quadrature formulae for analytic functions on ellipses-a survey of recent results. ETNA - Electronic Transactions on Numerical Analysis

This paper presents a survey of recent results on error estimates of Gaussian-type quadrature formulas for analytic functions on confocal ellipses

Optical and Electron Spectrometry of Molecules of Biological Interest

Optical absorption and emission spectroscopy together with low energy electron interaction (elastic scattering, excitation, ionization, resonances) with biologically relevant molecules (nitrogen, oxygen, water, alcohols, tetrahydrofuran, tetrahydrofurfuril alcohol, 3-hydroxytetrahydrofuran, pyrimidine, glycine, alanine) are studied in order to understand radiation damage and to investigate the presence of pollutants in the atmosphere. Versatile high resolution electron spectrometers are used in the present study of electron-molecule interactions. Energy loss spectra were recorded for these molecules in order to identify electronic transitions from ground state to both allowed and optically forbidden states. Optical emission spectra have been recorded from gas discharge processes by low resolution optical spectrometer (Ocean Optics 2000). Also, electronic spectra were compared with high resolution synchrotron photoabsorption spectra where these spectra had been available. Experimental methods of absorption-based laser spectroscopy were reviewed being of the most widely used analytical tools for detection of a specific molecule and quantitative measurements, based on the Beer-Lambert absorption law

Comparison between Routing Protocols for Wide Archeological Site

The paper shows a comparison between three routing protocols for WSN. The protocols are conceived for particular scenario easily findable in archeological site and take into account energy consumptions and robustness of the transmission. This study will show which of the three protocols better meets the needs of this particular scenario

A Simple Takagi-Sugeno Fuzzy Modelling Case Study for an Underwater Glider Control System

this paper is a section of several preliminaryvstudies versus the realization of Underwater Drones of the Università degli Studi “Roma Tre” Science Department: we describe an application of Takagi-Sugeno fuzzy logic modelling to the longitudinal control for the underwater glider in order to simplify the calculation effort
