Il sottotitolaggio per i film festival: due esperienze pratiche

This dissertation aims to examine the field of film festival subtitling by means of the analysis of two subtitling experiences. These experiences will be approached both on a methodological and on a practical level in order to analyse how subtitlers put theory into practice. This approach will also help underline the existing differences in work methodology as far as different work experiences are concerned. The subtitling experiences examined in this dissertation are part of my internships as a subtitler in two Italian film festivals, namely “Umbria Film Festival” and “900 Fest”. In this dissertation, I chose to focus on the subtitling of two of the audiovisual products I translated. These products are a German documentary titled Befreier und Befreite and a Danish fiction film titled Stille Hjerte. This dissertation is divided into five chapters. Chapter 1 describes audiovisual translation at its most theoretical level, focusing on subtitling criteria and strategies. Chapter 2 examines the concept of film translation, focusing on the distinctive features of documentary translation as a specific genre. This chapter also presents the concept of film festival and provides information concerning the translation policies of festivals. Chapter 3 presents the festivals I worked for and details my internship experiences. Chapter 4 focuses on the German documentary and proposes a number of solutions to its main translation problems. Chapter 5 focuses on the Danish film and offers solutions to its translation problems. At the end of the dissertation, I will provide some comments on my internship experiences as well as on the practice of film festival subtitling.

Extraordinary transmission through a single coaxial aperture in a thin metal film

We investigate experimentally the transmission properties of single sub-wavelength coaxial apertures in thin metal films (t = 110 nm). Enhanced transmission through a single sub-wavelength coaxial aperture illuminated with a strongly focused radially polarized light beam is reported. In our experiments we achieved up to four times enhanced transmission through a single coaxial aperture as compared to a (hollow) circular aperture with the same outer diameter.We attribute this enhancement of transmission to the excitation of a TEM-mode for illumination with radially polarized light inside the single coaxial aperture. A strong polarization contrast is observed between the transmission for radially and azimuthally polarized illumination. Furthermore, the observed transmission through a single coaxial aperture can be strongly reduced if surface plasmons are excited. The experimental results are in good agreement with finite difference time domain (FDTD) simulations.

Thin-Film Sparse Boundary Array Design for Passive Acoustic Mapping During Ultrasound Therapy

A new 2-D hydrophone array for ultrasound therapy monitoring is presented, along with a novel algorithm for passive acoustic mapping using a sparse weighted aperture. The array is constructed using existing polyvinylidene fluoride (PVDF) ultrasound sensor technology, and is utilized for its broadband characteristics and its high receive sensitivity. For most 2-D arrays, high-resolution imagery is desired, which requires a large aperture at the cost of a large number of elements. The proposed array's geometry is sparse, with elements only on the boundary of the rectangular aperture. The missing information from the interior is filled in using linear imaging techniques. After receiving acoustic emissions during ultrasound therapy, this algorithm applies an apodization to the sparse aperture to limit side lobes and then reconstructs acoustic activity with high spatiotemporal resolution. Experiments show verification of the theoretical point spread function, and cavitation maps in agar phantoms correspond closely to predicted areas, showing the validity of the array and methodology.
