Intelligent Transport Systems use
communication technologies to offer real-time traffic
information services to road users and government
managers. Vehicular Ad Hoc Networks is an important
component of ITS where vehicles communicate
with other vehicles and road-side infrastructures,
analyze and process received information, and
make decisions according to that.
However, features like high vehicle speeds, constant
mobility, varying topology, traffic density, etc.
induce challenges that make conventional wireless
technologies unsuitable for vehicular networks. This
paper focuses on the process of designing efficient
vehicle-to-vehicle and vehicle-to road-side infrastructure
The main goal of a voice conversion system is to modify the voice of a source speaker, in order to be perceived as if it had been uttered by another specific speaker. Many approaches found in the literature convert only the features related to the vocal tract of the speaker. Our proposal is to convert those characteristics, and to process the signal passing through the vocal chords. Thus, the goal of this work is to obtain better scores in the voice conversion results.
In tasks requiring human supervision
in an industrial control room there are applied generic
disciplines like automatic control and engineering
systems. From the point of view of the human
computer interaction applied to these disciplines it is
necessary to add usability engineering and cognitive
ergonomics. This integrated framework is an example
of human-centred design on automation systems.
The main goal of this work is the application of a
cognitive ergonomic guideline for supervisory control
in order to improve the efficiency of a sugar mill
Solid phase microextraction (SPME) was applied to the analysis of a selected group of non halogenated solvents -all of them classified as volatile organic compounds (VOCs)- that may be present in diverse industrial wastewaters. Two different fibres (100-PDMS and 85-PA) were selected as SPME adsorbents. The extracted volatile organic compounds were analysed by high resolution gas chromatography coupled to mass spectrometry (GC-MS), following the EPA method 624. Calibration curves and method deletion limits obtained for these solvents using the two SPME fibres are reported. The 100-PDMS fibre provided better sensitivity, but the saturation was reached at a lower concentration than 85-PA fibre. The first fibre (100-PDMS) was applied to the analysis of several textile wastewaters. The method detection limits obtained with this fibre were: 0.1-0.3 μ/L for ethylbenzene m-xylene p-xylene toluene and diisobutyl ketone. In addition SPME and Headspace (HS) detection limits were compared.
