Combinatorial chemistry was shown to be an efficient tool for the preparation of new aroma-impact compounds. In this case, polyfunctional thiols were synthesized quickly using halide reagents or Bunte salt intermediates. They were separated by gas chromatography and then characterized using low resolution EI and CI mass spectrometry. The individual sensorial properties of the thiol products (i....

The volatile compounds present in wines are responsible for the quality of the wine aroma. The analysis of these compounds requires different analytical techniques depending on the type of compounds and their concentration. The importance at sensorial level of each compound should be evaluated by using olfactometric techniques and reconstitution and omission studies. In addition, wine aroma is ...

Operator perception could be improved by upgrading force feedback devices and adding more senses, such as audio and/or visual. This work is focused on multi-sensorial feedback such as vision, sound, and haptic. The main objective is to determine the most suitable manner to show proper information from the remote environment using devices with a bandwith lower than 30 Hz. The advantage of this d...

Sound-induced flash illusions, first described in 2000, provide a valid example of perception as a multisensorial experience where all sensorial modalities work together. Audio-visual illusions can be classified in “fission” and “fusion” illusions. Whether one flash is accompanied by two or three auditory stimuli (or beeps), it’s often perceived as multiple flashes (fission illusion), by contra...

This paper is focused on the intelligent control of vehicles with nonholonomic constraints. A new method to compute a fuzzy perception of the environment is presented, dealing with the uncertainties and imprecisions from the sensorial system and taking into account nonholonomic constraints of the vehicle. This fuzzy perception is used, both in the design of each reactive behavior and solving th...

The research in the field of Advanced Driving Assistance Systems (ADAS) is oriented towards improving the safety, quality, mobility, and efficiency of driving. The first generation of ADAS was limited to mere passive assistance through warnings; for such systems the perception of the environment through various, complementary sensors was the main objective. As the ADAS evolve and incorporate ac...

protein content and its effect on the quality of fresh pastas, obtained from dough preparedwith different formulas: semolina, wheat flour, gluten, wheat bran and soybean proteins, were evaluatedin this paper. tests were carried out in the laboratory using raw materials from the same batch nationalorigin. raw materials were mixed in an auxiliary kneading machine with a 500 g -capacity. the dough...

Yeast strains contribute to the oenological and sensorial characteristics of the wines they produce. The present study was performed to determine the influence of Saccharomyces cerevisiae strains on the composition and sensorial properties of Albariño wine. The must obtained from Albariño grapes was inoculated with 12 different yeast strains isolated from a single winery in Galicia, Spain. Chem...

The phenomenological relationship between consciousness and sleep are reviewed. Consciousness has a selfreflexive component, and while sleeping that is not working as in awakenings. The necessity of some change in narrow concepts of conscious as to be aware and self reflective as well of some aspects of Altered State of Consciousness are explained. In fact, in rapid eye movements [REM] sleep is...
