Abstract: A method of simulating a quantum state using a quantum computer is provided. The method includes simulating a quantum state of a target molecule using the quantum computer, measuring a Hamiltonian in a simulated quantum state of the target molecule, calculating energy from the Hamiltonian measurements, and calculating a ground state and ground energy of the target molecule through an optimization process of deriving a lowest energy state by adjusting parameters that determine the quantum state of the target molecule, wherein simulating of the quantum state is performed with the configuration of a quantum circuit in which one quantum bit (qubit) is assigned to a pair of spin orbitals.

Abstract: A non-cylinder type composite pressure vessel of a vehicle is provided. The vessel includes a nozzle boss that includes a neck part having a hollow portion and a flange part that extends outward from the neck part. Additionally, a liner is engaged with the nozzle boss, thereby forming in the inside thereof a fluid filling space. The liner is formed stepped along a rim of an outer side of a reinforced area formed at an end portion of the fluid filling space.

Abstract: A method for manufacturing a pressure vessel includes blow-molding a liner vessel in a shape having at least one bulkhead and two or more separated spaces and inserting a bulkhead reinforcing plate between the separated spaces. The method further includes forming an outer layer comprising a glass fiber or a glass fiber-carbon fiber composite material on the outside of the liner vessel and forming at least one anchor site configured to couple the bulkhead reinforcing plate to the outer layer.

Abstract: A spring member of a suspension for a vehicle may include a spring provided to be supported between a lower seat disposed in the suspension and a car body to provide an elastic force, wherein an inner part of the spring is formed in a shape of a hollow corrugated tube.

Abstract: Disclosed is a corrugated plastic composite spring for a vehicle suspension and an apparatus and method for manufacturing the same. The apparatus includes a corrugated extrusion part, a braiding part, and a pultrusion part. The corrugated extrusion part forms a preform having a hollow corrugated structure. The braiding part weaves a three-dimensional woven fabric on the preform. The pultrusion part impregnates the three-dimensional woven fabric with thermosetting resin.
