Abstract: A method for manufacturing a box-shaped structure for aircrafts (1) is described (4), the structure (1) extending along a longitudinal direction (A) between a first longitudinal end (1a) and a second longitudinal end (1b), and comprising: a first longitudinal wall (5); a second longitudinal wall (6) facing the first wall (5) and arranged spaced from the first wall (5) by a non-zero amount; a plurality of spars (7) extending longitudinally and between said first wall (5) and second wall (6); and at least one reinforcing rib (23) arranged transversal to the spars (7) at a transversal sector (S1) interposed between the first and the second longitudinal end; each spar has a spar cavity (21) defining a lack of material extending longitudinally from an axial coordinate (X), which corresponds to the transversal sector (S1), up to the second longitudinal end, so that the reinforcing rib (23) can be easily inserted even after the integral coupling between the first wall, the second wall and the spars without compromising the structural properties of the box-shaped structure (1).

Abstract: A mandrel (300) for a molding process that includes a first portion (302) that has a first portion outer surface (306), a first portion inner surface (312), a first portion first end (303), and a first portion second end (305). A thickness (Hi) of the first portion first end (303) is greater than the first portion second end (305). A second portion (304) has a second portion outer surface (310), a second portion inner surface (308), a second portion first end (303), and a second portion second end (305). A thickness (H 2 ) of the second portion first end (303) is smaller than the second portion second end (305). The first portion inner surface (312) engages the second portion inner surface (308) to form a mandrel that has a constant cross-section.

Abstract: Methods, systems and apparatus for simulating quantum systems. In one aspect, a method includes the actions of obtaining a first Hamiltonian describing the quantum system, wherein the Hamiltonian is written in a plane wave basis comprising N plane wave basis vectors; applying a discrete Fourier transform to the first Hamiltonian to generate a second Hamiltonian written in a plane wave dual basis, wherein the second Hamiltonian comprises a number of terms that scales at most quadratically with N; and simulating the quantum system using the second Hamiltonian.

Abstract: A method, apparatus, and system for forming a composite structure. A mandrel system comprises a frame, segments, a connection system, and a seal system. The segments are connected to the frame. The segments provide an inner mold line for a composite structure. The connection system connects the segments to the frame. The seal system seals segment-to-segment joints in locations where the segments are joined to each other.
