Accurate approximate closed-form solutions for the cubic-quintic Duffing oscillator are obtained in terms of elementary functions. To do this, we use the previous results obtained using a cubication method in which the restoring force is expanded in Chebyshev polynomials and…

This paper will analyse the main marked syntactic structures of thematization in English in the play Sponono, written by Alan Paton in 1965. The analysis will point out that due to the use of these thematization processes in the play,…

The Sub-Numidian Tertiary stratigraphic record of the Tunisian Tell has been updated by means of 11 stratigraphic successions belonging to the Maghrebian Flysch Basin (N-African Margin) reconstructed in the Tunisian Numidian Zone and the Triassic Dome Zone. The Sub-Numidian successions…

Video 4 from paper "BUOYANCY EFFECT ON THE ULTRAFILTRATION OF PEG10000. VISUALIZATION BY DIGITAL HOLOGRAPHIC INTERFEROMETRY", submitted to AIChe Journal, 2011. Video shows the first 15 min after the pressure ceased. The speed in the video is increased 15 times,…

We propose a new algorithm to obtain the color matching functions of any digital camera, with correct weights and white balance, from the relative scaling of their complete (3-D) spectral sensitivities obtained from real spectroradiometric data. Thanks to this algorithm,…

An algorithm is proposed for the spectral and colorimetric characterization of digital still cameras (DSC) which allows them to be
used as tele-colorimeters with CIE–XYZ color output, in cd/m2. The spectral characterization consists in the calculation of the
color-matching functions…

Purpose – The aim of the paper is to study the reasons for the adoption and certification of quality systems and the subsequent impacts on performance. Design/methodology/approach – The methodology selected is a study based on the perceptions of two…

In this research we examined the opinions of basketball stakeholders regarding several questions of special interests to valuate players. Players, coaches, agents, journalists, editors, bloggers, researchers, analysts, fans and chairs participated in this macro-research. After analysing their opinions using the…

Video 5 from paper "BUOYANCY EFFECT ON THE ULTRAFILTRATION OF PEG10000. VISUALIZATION BY DIGITAL HOLOGRAPHIC INTERFEROMETRY", submitted to AIChe Journal, 2011. Video shows the first 3 min at the beginning of experiment but it reproduces the images at three times…

We estimated the number of colors perceived by color normal and color-deficient observers when looking at the theoretic limits of object-color stimuli. These limits, the optimal color stimuli, were computed for a color normal observer and CIE standard illuminant D65,…
