The Impact

This paper reports an experimental study on the impact of time-compressed speech on acceptability and intelligibility of utterances in Brazilian Portuguese. For the experiments, short audio sentences containing warning messages were used as stimuli. These sentences were recorded in a natural speech rate and then digitally manipulated to faster rates in a scalar fashion (from 9 to 19 syllables per second). Intelligibility and acceptability tests were then conducted with blind and sighted subjects. The results indicate that time-compressed speech has a significant impact on both acceptability and intelligibility of utterances for both groups of participants and that while blind subjects tended to give slightly higher acceptability rates across all speech rate conditions, sighted subjects performed better in the intelligibility experiment, what contradicts a trend that is often reported in the literature

Exchanger Tube

The current study experimentally investigates the heat transfer augmentation on the novel axial corrugated heat exchanger tube in which the spring tape is introduced. Air (Pr = 0.707) is used as a working fluid. In order to augment the thermohydraulic performance, a corrugated tube with inserts is offered. The experimental study is further extended by varying the important parameters like spring ratio (y = 1.5, 2.0, 2.5) and Reynolds number (Re = 10 000–52 000). The angular pitch between the two neighboring corrugations and the angle of the corrugation is kept constant through the experiments at β = 1200 and α = 600 respectively, while two different corrugations heights (h) are analyzed. While increasing the corrugation height and decreasing the spring ratio, the impact of the swirling effect improves the thermal performance of the system. The maximum thermal performance is obtained when the corrugation height is h = 0.2 and spring ratio y = 1.5. Eventually, correlations for predicting friction factor (f) and Nusselt number (Nu) are developed.

Os fenômenos de elipse são estudados a partir de duas hipóteses conflitantes: A hipótese semântica, que defende que a identifcação elipse-antecedente é de natureza semântica, não sendo necessário propor a existência de estrutura sintática; e a hipótese sintática, que argumenta a favor da existência de identifcação estrutural entre a elipse e o antecedente. Teorias alternativas têm relacionado condições de licenciamento de elipse a questões de estrutura informacional, especialmente considerando os conceitos de foco e tópico. Neste artigo, como forma de testar as hipóteses acima, realizou-se um estudo prosódico de sentenças elípticas produzidas por 12 falantes do PB do sexo feminino e com idade entre 20 e 35 anos. O teste consistiu de cinco sentenças para serem completadas pelos participantes e 28 imagens contendo duas cenas; em cada cena havia pelo menos um item diferente (ação, objeto ou sujeito). Os resultados mostraram um padrão interessante. No caso de elipse, a informação dada foi geralmente desacentuada, enquanto a informação contrastada (ação, objeto ou sujeito) foi entoacionalmente marcada por contorno alto (H) ou baixo-alto (LH). Se considerarmos que itens contrastivos são movidos para a periferia à esquerda, deixando um traço na posição original, então, pode-se deduzir que nesses casos há estrutura sintática desacentuada.

The Impact

With the extensive growth of the Internet and electronic commerce, the issue of how users behave when confronted with long download times is important. This paper investigates Web switching behavior. The paper describes experiments where users were subjected to artificially delayed Web page download times to study the impact of Web site wait times on switching behavior. Two hypotheses were tested. First, that longer wait times will result in increased switching behavior. The implication being that users become frustrated with long waiting times and choose to go elsewhere. Second, that users who switch will benefit, in terms of decreased download times, from their decision to switch.
