Abstract: An acoustic panel for an aircraft providing noise attenuation over a wide frequency band by combining two resonators, and acoustic panel manufacturing method. The acoustic panel includes a rear skin, a cellular structure, an intermediate layer including perforations, a cellular structure, a cellular structure and a resistive skin including perforations. The acoustic panel combines quarter-wave resonators with Helmholtz resonators to provide noise attenuation over a wide frequency range.

Abstract: An assembly jig for a cellular structure made from strips of material placed adjacent to each other and joined together so as to form first and second cells, opening on the first and second faces of the cellular structure, respectively. This assembly jig includes a housing delimited by a base and first and second side faces, configured for housing the strips of material of a cellular structure to be formed, superimposed on each other, a plurality of pins configured to be positioned between the superimposed strips of material in the first and/or second cells. An assembly device comprising the jig, and a method for manufacturing a cellular structure using the jig are also provided.

Abstract: A method for manufacturing a cellular structure having first and second faces, rows of cells each alternatingly having first cells, which are open in the direction of the first face, second cells, which are open in the direction of the second face, and also third cells formed between each row of cells, each row of cells comprising first and second strips of material placed against one another. The first and second strips of material are shaped by bending. By contrast to plastic deformation, shaping by bending makes it possible to expand the choice of materials and thicknesses for the first and second strips of material. An advantageous cellular structure is thus obtained as well as an acoustic absorption coating comprising such a cellular structure.

Abstract: The present technology generally relates to a system and to a method automated resource management. The method comprises obtaining a sorted list of employees based on vacancies to be filled; wherein each vacancy of the vacancies to be filled comprises a timeslot and a responsibility. The method comprises contacting employees in the sorted list and proposing available timeslots and responsibilities; receiving timeslot and responsibility preferences of the contacted employees; and resorting list of employees based on received timeslots and responsibilities preferences.

Abstract: The present application relates to boron nitride nanotube (BNNT)-silicate glass composites and to methods of preparing such composites. The methods comprise mixing BNNTs that are coated with a glass former such as boron oxide with a silicate glass precursor to create a mixture; heating the mixture under conditions to obtain a molten silicate glass; and cooling the molten silicate glass under conditions to obtain the BNNT-silicate glass composite.

Abstract: The porous material of the present invention is produced by heating a dry powder mixture, containing mainly an organic solid binder and inorganic particles. The mixture is foamed while the organic binder is melted. Foaming comes from a foaming agent in the powder mixture. The solid foamed structure comprising inorganic particles embedded in an organic binder is then heated to eliminate the organic binder and finally to sinter the remaining inorganic tri-dimensional network into a rigid structure having interconnected porosity.
