No full textOmelia e Commento sul vangelo di Giovanni. /
No full textComposti da Giovanni Scoto Eriugena forse verso la fine della sua vita, l?'Omelia' e il 'Commento' sul vangelo di Giovanni' costituiscono una testimonianza preziosa della sua attività di pensatore e di esegeta. Le due opere, di fortuna diversa (diffusissima la poetica 'Omelia', bozza incompiuta il 'Commento'), a una lettura congiunta permettono di scoprire man mano, lemma dopo lemma, la fisionomia intellettuale di questo maestro irlandese del IX secolo: l'espressività del poeta, l'attenzione del filologo e traduttore dal greco, la sottigliezza speculativa del filosofo e la fantasia dell?esegeta concorrono al fascino multiforme di queste pagine. Vi si ritrovano tutti gli elementi principali della sintesi teologico-filosofica di Eriugena, operata a partire dai Padri della Chiesa sia greci che latini, con le sue tesi a volte ardite, sempre suggestive: la progressione della rivelazione divina, la natura simbolica del cosmo e del testo sacro, il problema della visione di Dio e la divinizzazione dell?uomo.0.Composti da Giovanni Scoto Eriugena forse verso la fine della sua vita, l?'Omelia' e il 'Commento' sul vangelo di Giovanni' costituiscono una testimonianza preziosa della sua attività di pensatore e di esegeta.

Short-Range Microwave Imaging Technique Based on an Inexact-Newton Method for the Nondestructive Inspection of Dielectric Objects
No full textIn this paper a short range microwave imaging algorithm is presented for non invasive diagnostic purposes related to security applications. The algorithm can be used in imaging systems where the presence of dielectric targets is detected by the "inversion" of measured samples of the scattered electric field. In particular, the proposed approach is based on the electromagnetic scattering equations in the spatial domain. In fact, despite frequency domain methods, such formulation allows a resolution which is ideally not affected by the wavelength. More specifically, an inexact Newton method is proposed and analysed as a regularizing tool to solve the nonlinear and highly ill-posed inverse scattering problem arising in imaging problems. The theory underlying these approach is provided and the results of some numerical simulations in noisy environments are reporte

A Study of Bozza\u27s Eighteen Etudes In The Form of Improvisation For Horn and New Preparatory Etudes on the Works of Bozza
No full textThis document serves as an analysis of Eugene Bozza\u27s Dix-Huit Études en Forme d\u27Improvisation pour Cor (1961), translated to Eighteen Etudes in the Form of Improvisation for Horn for the purposes of this document. I found and documented all motifs within the eighteen etudes, and categorized connections between them and Bozza\u27s compositional ouerve as displayed in Dr. Lois Kuyper-Rushing\u27s A Thematic Index of the Works of Bozza. My research takes inspiration from Dr. Kuyper-Rushing\u27s work as well as Dr. Hsing-Fang Liu\u27s research involving Bozza\u27s use of “Adoptive Transcription”, or taking old melodies from previous works and using them in new works. Involved with this document is a recording of all eighteen etudes, recorded and performed by the author at the Barth House, a local Episcopalian center in Memphis, Tennessee. A discussion of each of the 18 etudes, their connections, and the process I had taken in practicing and recording them makes up the middle section of the document. Finally, using the knowledge gained from the connections made and the recordings provided, this document will conclude with three new preparatory etudes for the horn composed by the author in the spirit of making the performance of Bozza\u27s body of work easier for future horn students. In their current state, most of Bozza\u27s Eighteen Etudes in the Form of Improvisation are simply too difficult to be played well by intermediate students
Development of a 0D multi-zone model for fast and accurate prediction of homogeneous charge compression ignition (HCCI) engine
No full textHomogeneous Charge Compression Ignition (HCCI) is a
promising advanced combustion mode, featured by both high thermal
efficiency and low emissions. In this context, a 0D multi-zone model has
been developed, where the thermal stratification in the combustion
chamber has been taken into account. The model is based on a control
mass Lagrangian multi-zone approach. In addition, a procedure based on a
tabulated approach (Tabulated Kinetic of Ignition - TKI) has been
developed, to perform an accurate and fast prediction of the air/fuel
mixture auto-ignition. This methodology allows combining the accuracy of
detailed chemistry with a negligible computational effort. The tabulated
procedure has been preliminarily verified through the comparison with the
results of a commercial software (GT-PowerTM). In this assessment, single
zone simulations have been performed comparing the TKI strategy to a
conventional chemical kinetics one, in four different cases at varying the
intake temperature and the equivalence ratio. Then, the proposed 0D multi-zone
model has been validated against experimental data available in the
literature. The analyses are carried out with reference to an HCCI engine
fuelled with pure hydrogen and working in a single operating point,
namely 1500 rpm, 2.2 bar IMEP and with a fuel/air equivalence ratio of
0.24. Three different temperatures, i.e., 373, 383, and 393 K, have been
considered for the intake air. The experimental/numerical comparisons of
pressure cycles and burn rates proved that the proposed numerical
approach can reproduce the experiments with good accuracy, without the
need for case-by-case tuning
