Abstract: The invention relates to a method for producing or designing a leading edge of a lifting structure, wherein starting at the midpoint of the base (0,0), a curve is applied to the profile of the structure, the length “L1” of which is according to the maximum thickness of the NACA section in the base of the profile “H0” in the base and is defined by the equation L1=0.0510H02?0.0790H0+15.5790, and the maximum height of which on the “x”-axis is located at point “L1/2” and defined by means of the relationship x=0.0137(L1)1.4944, the shape of said curve being defined by means of the equation: (y?y0)=0.0000000107x6+0.0000016382x5?0.0000794412x4+0.0010194142x3+0.0097205322x2+0.0136993913x, and the rest of the curve being calculated by means of an iterative process according to the above.

Abstract: System for detecting the level of discomfort of aquatic animals during experimental studies, with a water tank, a reference electrode placed at one of the sides of the tank, at least one recording electrode placed at another side of the tank, a bio amplifier for amplifying a received bio-signal at the recording electrode, a microprocessor for treating the signals and a low-pass filter for filtering the signals received. The system can provide a precise, quantifiable and specific indication of the level of stress/wellbeing of aquatic animals in normal living conditions as well as in experimental conditions without interfering with the animals' life.

Abstract: Method and automatic system for the determination and the classification of foods based on a high-speed manipulation robot aided by a localization system which is capable of detecting the food which comes along a transport system in a random fashion without contact between one and the other, and to classify it; the robot incorporates a manipulation grip wherein a sensor which permits the determination and classification of the food is housed.
