    Abstract: A fuzzy method for the recognition of geometric shapes in images, the particularity whereof is that it comprises the following steps: recognition of at least one edge of a curve of an image; recognition of the gradient of the edge; correction of the gradient by virtue of first fuzzy means; and determination of the number of points that belong to the curve by virtue of second fuzzy means. The process according to the present invention is performed by a fuzzy device for the recognition of geometric shapes in images that comprises: an edge detector, adapted to recognize at least one edge of a curve of an image and adapted to recognize the gradient of the edge; a fuzzy gradient corrector, adapted to correct said gradient; a fuzzy vote attributor, adapted to determine the number of points that belong to the curve.

    Abstract: Filter achieving noise reduction and digital signal image edge exaltation comprising first and second noise reduction circuit means 2 and 3 designed to elect an image edge. Said first and second noise reduction circuit means 2 and 3 comprise each a first and second comparison element (S1,S2,S3,S4) whose input terminals are designed to receive separate digital signals of an image and an inferential circuit (C1,C2) connected to said comparison elements. Each inferential circuit (C1,C2) comprises a fuzzy logic unit designed to define activation levels (Vi) dependent upon signals generated by the comparison elements. The filter (1) comprises also a noise detection circuit (4) and an image edge detection circuit (6) both connected to the noise reduction circuit means (2,3) and designed to perform operations in accordance with fuzzy logic rules on the basis of activation levels (Vi) defined in the inferential circuits (C1,C2). The filter 1 also includes a noise reduction circuit (5) connected to the noise detection circuit (6) and designed to filter the digital image signals on the basis of the operations performed by the circuit (4). In the filter (1) is also included an image edge exalting circuit (7) connected to the noise reduction circuit (5) and to the image edge detection circuit (4) designed to perform on filtered digital image signals an image edge exaltation on the basis of the operations performed by the image edge detection circuit (6).

    Abstract: Method for realising a hosting structure of nanomettric elements (A, B) comprising the steps of depositing on an upper surface (12) of a substrate (10), of a first material, a block-seed (15) having at least one side wall (18). Depositing on at least one portion of sad surface (12) and on the block-seed (15) a first layer (20), of predetermined thickness of a second material, and subsequently selectively and anisotropically etching it realising a spacer-seed (22) adjacent to the side wall (18). The method thus providing to repeat n times, with n >= 2, a step comprising a deposition on the substrate (10) of a layer (20, 30) of a predetermined material followed by a selective and anisotropic etching of the layer with realisation of at least one relative spacer (25, 35). This predetermined material being different for each pair of consecutive depositions. The above n steps defining at least one multilayer body (50, 150, 250). The method thus providing the step of selectively etching the multilayer body (50, 150, 250) removing a fraction of the spacers realising at least one plurality of nanometric hosting seats (40), the remaining fraction of the spacers realising contact terminals for a plurality of molecular transistors hosted in said hosting seats (40).

    Abstract: A method of controlling a process driven by a control signal for producing a corresponding output includes producing an error signal as a function of a state of the process and of a reference signal. A control signal is generated as a function of the error signal and of a parameter adjustment signal. The control signal is applied to the process. A derived signal representative of a quantity to be minimized is calculated by processing paired values of the state of the process and the control signal. A correction signal is calculated from a set of several different values of the control signal that minimizes the derived signal. The parameter adjustment signal is calculated by a neural network and fuzzy logic processor from the error signal and the correction signal. The correction signal is periodically calculated by a Quantum Genetic Search Algorithm that results from a merging of a genetic algorithm and a quantum search algorithm.
