TR-2015001: A Survey and Critique of Facial Expression Synthesis in Sign Language Animation

Sign language animations can lead to better accessibility of information and services for people who are deaf and have low literacy skills in spoken/written languages. Due to the distinct word-order, syntax, and lexicon of the sign language from the spoken/written language, many deaf people find it difficult to comprehend the text on a computer screen or captions on a television. Animated characters performing sign language in a comprehensible way could make this information accessible. Facial expressions and other non-manual components play an important role in the naturalness and understandability of these animations. Their coordination to the manual signs is crucial for the interpretation of the signed message. Software to advance the support of facial expressions in generation of sign language animation could make this technology more acceptable for deaf people. In this survey, we discuss the challenges in facial expression synthesis and we compare and critique the state of the art projects on generating facial expressions in sign language animations. Beginning with an overview of facial expressions linguistics, sign language animation technologies, and some background on animating facial expressions, a discussion of the search strategy and criteria used to select the five projects that are the primary focus of this survey follows. This survey continues on to introduce the work from the five projects under consideration. Their contributions are compared in terms of support for specific sign language, categories of facial expressions investigated, focus range in the animation generation, use of annotated corpora, input data or hypothesis for their approach, and other factors. Strengths and drawbacks of individual projects are identified in the perspectives above. This survey concludes with our current research focus in this area and future prospects.

Borchert und Beckmann : Biographische Berührungspunkte Wolfgang Borcherts in seinem Drama Draußen vor der Tür

Nachkriegsliteratur, oder Kahlschlags- bzw. Trümmerliteratur wurde zwischen 1945 und 1950 geschrieben. Es war die junge Schriftstellergeneration in der Westzone, die von ihren Erfahrungen mit dem Nationalsozialismus, dem Krieg, dem Leben in Trümmern schrieb. Die Themen dieser Literatur sind demnach Krieg, Tod, Untergang, Gefangenschaft, Trümmer, Heimkehr und Überlebungskampf. Wolfgang Borcherts Drama Draußen vor der Tür ist das wichtigste Beispiel für die Trümmerliteratur und eins der wenigen Dramen, das in der Nachkriegszeit großes Publikum fand. In seinem Drama Draußen vor der Tür, das Borchert einige Monate vor seinem Tod im Jahre 1947 schrieb, geht es um einen Soldaten, Beckmann, der nach 3 Jahren Gefangenschaft in Sibirien in seine zertrümmerte Heimat zurückkehrt. Das Drama wird als ein Protestschrei gegen den Krieg gesehen. Mit Wolfgang Borcherts Lebensgeschichte als Hintergrund entstand die Frage, welche biographischen Berührungspunkte sich in Borcherts Drama Draußen vor der Tür finden lassen, also welche persönlichen Erlebnisse, Erfahrungen, Eigenschaften und Werte werden in seinem Drama widergespiegelt oder zum Ausdruck gebracht.

Encurtamento pelo frio de fibras musculares oxidativas de bovinos pela técnica de NADH-TR

Carcaças bovinas resfriadas rapidamente podem apresentar uma contração muscular conhecida como encurtamento pelo frio. Esse fenômeno, prejudicial à textura da carne, ocorre principalmente nas fibras musculares oxidativas. O objetivo deste trabalho foi disponibilizar uma ferramenta analítica para distinguir essas fibras e determinar com maior precisão a contração do tecido muscular pela mensuração do comprimento dos sarcômeros. Amostras do músculo Longissimus dorsi de 12 novilhas nelore foram coletadas. As amostras obtidas de uma das meias-carcaças foram submetidas a uma refrigeração rápida, e as amostras provenientes da outra meia-carcaça à refrigeração lenta. Foi testado um método analítico, baseado na técnica de coloração por Nicotinamida Adenina Dinucleotídeo - Tetrazolium Redutase (NADH-TR), para mensurar, por microscopia, o comprimento dos sarcômeros das fibras vermelhas. Foram determinadas as velocidades de queda de pH e temperatura, a área do olho de lombo (AOL) e a força de cisalhamento. Os resultados demonstraram que a temperatura é o principal fator responsável pelo comprimento do sarcômero quando a velocidade de resfriamento é rápida, sendo essa influência menor quando a queda de temperatura é mais lenta. Desta forma, demonstrou-se que a técnica de coloração com NADH-TR é capaz de detectar a ocorrência do encurtamento pelo frio nos músculos esqueléticos de bovinos.

Comparação entre trȩs métodos para estimar lâminas de irrigação

An experiment with four treatments was carried out on the experimental area of ADEI to compare three methods of water use requirement: ETc (T1) - irrigation based on crop evapotranspiration (ETc); Tensiometers (T2 and T3) - irrigations were made through reading of tensiometers installed at 40 cm deep and, Control (T4) - only one irrigation to promote the seedlings emergence. Both Class A pan and soil water depletion methods presented good results when the crop was developed without restraint of water. The Katerji method can be utilized in conditions of water restriction. Irrigation frequency was more important than amount of applied water for higher yield.

Modulation of thyroid hormone receptors, TRα and TRβ, by using different doses of triiodothyronine (T3) at different times

Objective: To examine the effect of different doses of triiodothyronine (T3) on mRNA levels of thyroid hormone receptors, TRα and TRβ, at different times. Materials and methods: 3T3-L1 adipocytes were incubated with T3 (physiological dose: F; supraphysiological doses: SI or SII), or without T3 (control, C) for 0.5, 1, 6, or 24h. TRα and TRβ mRNA was detected using real-time polymerase chain reaction. Results: F increased TRβ mRNA levels at 0.5h. After 1h, TRα levels increased with F and SI and TRβ levels decreased with SII compared with C, F, and SI. After 6h, both genes were suppressed at all concentrations. In 24h, TRα and TRβ levels were similar to those of C group. Conclusions: T3 action with F began at 1h for TRα and at 0.5h for TRβ. These results suggest the importance of knowing the times and doses that activate T3 receptors in adipocytes.

Internazionalizzazione e traduzione: Un'esperienza presso l'azienda TR Turoni S.R.L.

This dissertation was conducted within the project Language Toolkit, which has the aim of integrating the worlds of work and university. In particular, it consists of the translation into English of documents commissioned by the Italian company TR Turoni and its primary purpose is to demonstrate that, in the field of translation for companies, the existing translation support tools and software can optimise and facilitate the translation process. The work consists of five chapters. The first introduces the Language Toolkit project, the TR Turoni company and its relationship with the CERMAC export consortium. After outlining the current state of company internationalisation, the importance of professional translators in enhancing the competitiveness of companies that enter new international markets is highlighted. Chapter two provides an overview of the texts to be translated, focusing on the textual function and typology and on the addressees. After that, manual translation and the main software developed specifically for translators are described, with a focus on computer-assisted translation (CAT) and machine translation (MT). The third chapter presents the target texts and the corresponding translations. Chapter four is dedicated to the analysis of the translation process. The first two texts were translated manually, with the support of a purpose-built specialized corpus. The following two documents were translated with the software SDL Trados Studio 2011 and its applications. The last texts were submitted to the Google Translate service and to a process of pre and post-editing. Finally, in chapter five conclusions are drawn about the main limits and potentialities of the different translations techniques. In addition to this, the importance of an integrated use of all available instruments is underlined.

Selective removal of anomeric O-acetate groups in carbohydrates using HCl04-Si02-tr

A convenient methodology has been developed for the selective removal of the anomeric acyl group of carbohydrate derivatives using HCI04-Si02 under acidic reaction conditions. Anomeric benzoyl groups can also be removed selectively following similar reaction conditions. The yields were excellent in all cases.
