Abstract: A panel for self-supporting ducts, in particular air-conditioning ducts, made up of a core of mineral wool, covered on its external face with an exterior covering joined to the external surface of the core, the exterior covering including a sheet of aluminum and the sheet of aluminum being the outermost sheet of the exterior stack, wherein the sheet of aluminum exhibits, at least on its outwardly exposed face, diffuse reflection greater than its specular reflection.

Abstract: Method for installing a hollow concrete tower comprising the following steps: a) arranging a platform on a site; b) arranging on said platform at least one partial full-segment mould in a position such that the segment axis of the segment being cast in said mould is substantially vertical; c) pouring concrete inside said arranged partial mould(s); d) allowing the poured concrete to set to working strength, generating corresponding segment(s); e) removing the arranged mould(s) with concrete set to working strength, to leave the corresponding segment(s) exposed; f) assembling said corresponding exposed segment(s); and g) optionally, repeating steps b)-f) at least once.

Abstract: A panel for self-supporting ducts, in particular air-conditioning ducts, made up of a core of mineral wool or the like, covered on its external face and on its internal face with an exterior covering and an interior covering, respectively. The interior covering includes or preferably is made up of an aluminum sheet, a layer of a glass fabric or a layer of a glass web. The exterior covering includes the succession of a first layer of plastics material, an aluminum sheet, and a second layer of plastics material. The layers of plastics material are bonded to the aluminum sheet directly or via an adhesive. The exterior covering is bonded to the external surface of the core by glue.

Abstract: The present disclosure proposes a new model engineering method and system that permits the creation of application systems without the need of program development. The system allows organizations to search for high performance development teams and methods, and develop high quality solutions. The present disclosure covers the three central areas of systems engineering: (1) a method for creating models which represent reality in a standardized way; (2) a procedure for transforming models into computable artifacts, that is, computer systems that behave as specified in the model; and (3) a collaborative method based in knowledge representations.

Abstract: The invention relates to a tongue-and-groove coupling between panels of self-supporting air-conditioning ducts and the like, of the type that is provided in order to establish an optimum fit of the canted edge corresponding to the panels that are coupled in a tongue-and-groove manner, and also, to avoid the air coming into contact with the core of the duct therein. To this end, the panels consist of a core of insulating material complemented by an outer layer and inner layer based on aluminum or some other coating, the juxtaposing canted edge or edge between the panels having an oblique cut in relation to the horizontality or longitudinal intermediate line in the joint between the two panels; the aluminum layer or coating, which determines the inner face of the duct, extending beyond the edge of the panel, and being fixed to the oblique surface that defines the coupling profile.
