Audio Description Washes Brighter? A Study in Brand Names and Advertising

Dealing with objects in audio description, and particularly with those objects that have a clear designer imprint or branding, is a complex matter when a brand name is part of the scene in a film. Deciding whether to describe or not, and how, becomes more than a technical matter that depends on text–image synchronization: it is a complex decision-making process comparable to other forms of audiovisual translation that needs to be approached as a paradigmatic example of intersemiotic translation. Dávila-Montes and Orero address the audio description of branded objects in movies, and their intersemiotic translation from images to spoken words, a complex issue that may harbour additional insights into topics of a wider scope

Tailoring the thermal conductivity of the powder bed in Electron Beam Melting (EBM) Additive Manufacturing

Metallic powder bed additive manufacturing is capable of producing complex, functional parts by repeatedly depositing thin layers of powder particles atop of each other whilst selectively melting the corresponding part cross-section into each layer. A weakness with this approach arises when melting overhanging features, which have no prior melted material directly beneath them. This is due to the lower thermal conductivity of the powder relative to solid material, which as a result leads to an accumulation of heat and thus distortion. The Electron Beam Melting (EBM) process alleviates this to some extent as the powder must first be sintered (by the beam itself) before it is melted, which results in the added benefit of increasing the thermal conductivity. This study thus sought to investigate to what extent the thermal conductivity of local regions in a titanium Ti-6Al-4V powder bed could be varied by imparting more energy from the beam. Thermal diffusivity and density measurements were taken of the resulting sintered samples, which ranged from being loosely to very well consolidated. It was found that the calculated thermal conductivity at two temperatures, 40 and 730 °C, was more than doubled over the range of input energies explored
