Algorithms designed to translate textual content into sign language (SL) expressed through avatars have been used to reduce accessibility barriers. Our research aimed to identify whether the VLibras tool, widely adopted on Brazilian government websites, is an effective accessibility solution for automatic translation into SL. It is an exploratory and applied qualitative research project involving a bibliographic review and support from expert interpreters. We conducted two experimental studies using sequential chronological cuts and applying prescriptive and semantic analyses. We present evidence that there is no actual translation into SL in the automatic translation process performed by the VLibras translation algorithm (TA) but only a transposition of part of the SL lexicon to the Portuguese morphosyntactic structure. The automatic translation of long texts and texts with complex syntactic structures results in excessive pauses and dactylology for words that have a sign registered in the basic SL dictionary. Using human–computer interaction concepts to evaluate automatic translation into sign language by the VLibras TA expands the existing theoretical discussion. It also contributes to minimizing communication problems caused by the discrepancy between the original message and the machine translation, a practical applicability of this study.
RESUMOConsiderando que a secagem é uma das principais etapas da lenha quando esta é utilizada para a geração de vapor, este trabalho apresenta uma análise do comportamento da secagem de lenha ao longo de um ano utilizada para alimentar caldeiras de uma empresa localizada no sul do Brasil. O escopo do estudo é o tipo de eucalyptus dunnii, porém se fez um comparativo com o tipo saligna para que fosse possível calcular os ganhos energéticos entre estas duas espécies em relação ao tempo de secagem, assim como um comparativo entre o poder calorífico de ambas as espécies. O trabalho também apresenta uma relação entre pilhas de lenha cobertas com lona e pilhas não cobertas, assim como seus resultados de custo/benefício. Foi possível constatar que a melhor época do ano para realização do corte da lenha, para a região em estudo, é até o final do mês de setembro, pois assim as pilhas terão, no mínimo, cinco meses de exposição aos meses de verão. Constatou-se também que pilhas cobertas conseguem reduzir a umidade para até 20%, e têm seu custo/benefício viável.Palavras-chave: Eucalyptus dunnii. Secagem da madeira. Análise econômica. ABSTRACTConsidering that drying is one of the main stages of wood used for the generation of steam, this paper presents an analysis of the drying process of wood used to feed boilers of a company located in the south of Brazil, over the period of one year. The scope of the present study is dunnii eucalyptus type. However a comparison with the saligna type was made in order to calculate the energetic gains between these two species in relation to their drying. And a comparison between the power generated by both species was made. The paper also presents a relationship between covered piles of firewood and uncovered piles, as well as their cost/benefit results. It was possible to verify that the best time of the year for the firewood cutting in the region under study is until the end of September, so the piles will have at least five months of exposure during the summer months. It has also been found that covered piles can reduce humidity up to 20%, and have a viable cost/benefit.
