Abstract: A horizontal axis wind generator comprises a wind turbine with a plurality of blades, which extend between a first portion at the turbine rotational axis and a second end portion, an electric power generator coupled with the wind turbine and having a rotor adapted to be set in rotation around a rotor rotational axis, motion transmission members for transmitting the rotation energy of the wind turbine to the rotor. The motion transmission members comprise a frame associated with the second end portions of the blades and the rotor is operatively coupled with the frame with an aerodynamic profile both for the inlet and for the outlet of the air flow.

Abstract: The invention deals with an aid device for reading a printed text, comprising a data acquisition peripheral with a camera and a communication interface, said peripheral being movable by a user on a printed text to frame a portion of text, a processing unit, communication means between the peripheral and the processing unit, and a vocal reproduction device. The processing unit is programmed to acquire a sequence of images framed by the camera, to detect when the user has stopped on the text, to recognize at least one word which the user intends reading, and to reproduce the sound of said at least one word by means of vocal synthesis by means of the vocal reproduction device.

Abstract: A method to determine if an encrypted flow of packets (F) belongs to a predefined class of flows (?t), comprises the steps of giving probability density functions (p(xi|?t)) of the values of two measurable variables in a plurality of encrypted flows of packets (Fj) belonging to the predefined class of flows (?t), measuring the values (si,?t1) of the two measurable variables, apply the measured values (si,?t1) to the probability density functions (p(xi|?t)) to generate a sequence of values of probability density (p({right arrow over (x)}|?t)), process the sequence of values of probability density (p({right arrow over (x)}|?t)) to generate a reference value (S({right arrow over (x)}|?t)), and compare such reference value (S({right arrow over (x)}|?t)) to a threshold value (T) to determine whether the encrypted flow of packets (F) belongs to the predefined class of flows.

Abstract: A process for attaching a polyethylene glycol compound to a macromolecule to prepare a conjugate or adduct between the polyethylene glycol compound and the macromolecule is described. The process comprises the steps of (1) preparing an activated PEG or an activated PEG derivative by incorporating an acrylic ester, an acrylic thioester or an acrylamido group into the PEG or PEG derivative; (2) reacting the activated PEG or PEG derivative with a macromolecular material comprising one or more sulphydryl groups, primary amino groups and/or secondary amino groups and (3) recovering the conjugate of the PEG or PEG derivative and the macromolecular material.
