Extended models of the W-PESQ method are presented which are capable of assessing the subjective quality of noisy speech signals sampled at 48 kHz. Two methods are proposed: a version backward compatible with the W-PESQ standard, called EW-PESQ(E), and another, called EW-PESQ(R), in which the original psychoacoustic models are entirely replaced with alternative formulations available in the literature. Performance figures of both the EW-PESQ(E) and the EW-PESQ(R) in predicting the subjective quality of extrawide-band speech (sampled at 48 kHz) corrupted with broad-band and environmental noise are reported. In both cases the results obtained reveal a strong correlation (approximately 97%) with mean opinion scores.

This paper aims at establishing a global landscape by means of the technological monitoring of cyclodextrin. In order to achieve this objective, the databases of the Web of Science were used for the survey of the scientific literature and the databases of the patents for the survey of the filings of patent applications. The data were obtained using suitable keywords. The present study has examined the publications and the patent applications published from 1981 to 2011. This has allowed us to assess, among other aspects, the main inventors, depositors and the country of the depositors, the main International Patent Classifications, the year of the publication, the country of the publication, as well as discuss the importance of patents as a means of encouraging technological innovation of cyclodextrin technologies. © 2014 Elsevier Ltd.

The present paper aims at mapping the Brazilian technologies in the oil, gas and coke industries. The research was done on the basis of the patent applications filed by residents at the National Institute of Industrial Property of Brazil (INPI) in the period from 1970 to 2007. The research has shown the technologies involved in the filings of patent applications that had had the greatest interest, over the period studied, were those related to IPC subclasses C10L, C10B and C10G. The subclass C10L was the subclass with the highest number of patents applications filed, highlighting groups C10L 1, liquid carbonaceous fuels (gasoline, diesel, biodiesel and ethanol), and C10L 5, solid fuels (source mineral, non-mineral-vegetable and animal). In the subclass C10B, the group C10B 49, destructive distillation of solid carbonaceous material, showed the highest number of patent applications filed. In the Subclass C10G, the group C10G 11, processes of catalytic cracking, showed the largest number of deposits of patent applications. It is noteworthy that 40% of deposits of patent applications occurred between 2000 and 2007. © 2012 Elsevier Ltd.
