Colorimetric change of assai (Euterpe oleracea Mart.) after preservation and thermal processing of the fruit.

Amazonian areas is far from the consumer center. Those characteristics promote a decline in visual quality of the fruit at the time of commercialization and consequently of the beverage processed. The aim of this study was to evaluate the influence of the assai fruit conservation and heat treatment, usually applied before its transformation into a pulp or beverage by artisan processing. Assai fruits were collected in 2013 in Mazagão, Brazil, packed in polypropylene bags, vacuum sealed and refrigerated (8-10°C) during four days. The treatments consisted of i.) fruits packed under vacuum (T1), ii.) fruits softening with potable water at 45°C for 20 minutes before bleaching (T2), ii.) fruits which have not been softened before bleaching (T3), iii.) fruits bleached at 80°C for 10 seconds (T4) (Rogez et al., 1996) and iv.) packaged fruit pulps prepared in the presence (T5) and iv). absence of vacuum (T6). The instrumental color of fruits and pulps was evaluated by colorimeter CR- 400 Konica Minolta. Fruit pulp preserved in vacuum (T5) showed the darkest luminosity (L*29.39), well as a more reddish color (a*8.51) and also more blue (b*-4.10). Considering ?E 12.55, there was a significant difference between vacuum packed fruit (T1) and without vacuum fruit pulps (T6). Otherwise, pulps from vacuum packed fruits (T5) and ones with absence of vacuum packed fruits (T6) also presented statistical difference (?E 7.80). The highest value C* was observed in vacuum packed pulps (T5) (9.45), which presented with a brighter and stronger color than the fruit pulp without vacuum (T6) (C*7.01). Regarding H°hue, the pulp from fruits without vacuum (T6) showed higher values (H°78.36) when compared to the pulp from fruits under vacuum (T5) (H°73.84). Compared to thermal processing, bleaching was not statistically influenced by purity of the color (C*) of softened fruit pulps (T2) (C*8.50) and fruit pulps that were not softening (T3) (C*8.00). The highest total color difference was observed in the bleached pulps that were previously softened (T4) (?E12.85). Assai fruits vacuum packed retain the best attributes of drink produced. Softening of the fruit before bleaching also influences the change in color of the drink, which may represent significant quality loss for the product and value for the merchant and consumers.UP371

Avaliação da aderência pneu-pavimento para diferentes tipos de pavimentos utilizando o International Friction Index (IFI)

A condição superficial do pavimento é um fator importante para a avaliação da segurança viária por caracterizar diretamente os níveis de atrito, que condicionam as frenagens veiculares. No intuito de padronizar os diversos indicadores de aderência, desenvolveu-se o International Friction Index (IFI). O principal objetivo deste método é quantificar o atrito superficial, reportando-o como um índice em escala que possa ser utilizado internacionalmente. Neste contexto, o presente estudo tem como objetivo avaliar a aderência pneu-pavimento para diferentes tipos de pavimentos utilizados no Brasil. Para isso, consolidou-se um extenso banco de dados, obtidos a partir da revisão da literatura, de microtextura e de macrotextura, englobando aproximadamente dez técnicas diferentes de pavimentação. Desta análise, obtiveram-se curvas que correlacionam coeficiente de atrito e a velocidade, observando-se a preponderância da macrotextura do material no desempenho da aderência pneu-pavimento.Pavement’s surface condition is a key parameter to evaluate traffic safety because it directly characterizes friction levels, related to the quality of vehicular braking. Defined by both micro- and macrotexture, different techniques applied to determine skid resistance are documented in the literature. In order to standardized skid resistance, International Friction Index (IFI) was developed. Its main goal is to quantify frictional coefficient, reporting it as a single-scale indicator, which can be assessed worldwide. In this context, this paper’s mean objective is to assess skid resistance for different paving techniques. For that, an extent database of micro- and macrotexture was collected from the literature, counting on more than 10 different paving techniques. From this analysis, curves of frictional coefficient versus speed were plotted, observing macrotexture’s preponderance on skid resistance performance.info:eu-repo/semantics/publishedVersio

Visser's Massive Gravity Bimetric Theory Revisited

A massive gravity theory was proposed by Visser in the late nineties. This theory, based on a backgroung metric $b_{\alpha \beta}$ and on an usual dynamical metric $g_{\alpha \beta}$ has the advantage of being free of ghosts as well as discontinuities present in other massive theories proposed in the past. In the present investigation, the equations of Visser's theory are revisited with a particular care on the related conservation laws.\ It will be shown that a multiplicative factor is missing in the graviton tensor originally derived by Visser, which has no incidence on the weak field approach but becomes important in the strong field regime when, for instance, cosmological applications are considered. In this case, contrary to some previous claims found in the literature, we conclude that a non-static background metric is required in order to obtain a solution able to mimic the $\Lambda$CDM cosmology.Comment: 10 pages - Accepted for publication in Physical Review

Verification of Magnitude and Phase Responses in Fixed-Point Digital Filters

In the digital signal processing (DSP) area, one of the most important tasks is digital filter design. Currently, this procedure is performed with the aid of computational tools, which generally assume filter coefficients represented with floating-point arithmetic. Nonetheless, during the implementation phase, which is often done in digital signal processors or field programmable gate arrays, the representation of the obtained coefficients can be carried out through integer or fixed-point arithmetic, which often results in unexpected behavior or even unstable filters. The present work addresses this issue and proposes a verification methodology based on the digital-system verifier (DSVerifier), with the goal of checking fixed-point digital filters w.r.t. implementation aspects. In particular, DSVerifier checks whether the number of bits used in coefficient representation will result in a filter with the same features specified during the design phase. Experimental results show that errors regarding frequency response and overflow are likely to be identified with the proposed methodology, which thus improves overall system's reliability
