Abstract: Techniques are disclosed for designing structures using a torsion-deformable spatial beam element. The beam element can be represented using the absolute nodal coordinate formulation, or any other technically feasible formulation. At each of one or more time steps, the Bishop frame is used to generate local coordinate systems along a center line of the beam element, which are used to compute a potential energy of the beam element (704). Thereafter, a derivative of the potential energy (708) is plugged into equations of motion that are solved to determine an updated state of the beam element (710). A representation of the updated beam element can also be rendered and displayed via a graphical user interface (712).

Filed: 2021-09-16
Abstract: An evaluation section (34) identifies, in a list of candidate compounds, a group of candidate compounds having the degree of reverse similarity greater than or equal to a threshold s1. When all candidate compounds in the group of candidate compounds have differences between the degrees of similarity that are greater than or equal to a threshold s2, the evaluation section (34) judges that there is a composite state. The difference between the degrees of similarity is computed by subtracting the degree of forward similarity from the degree of reverse similarity. The similarity ratio may be used in place of the difference between the degrees of similarity.

The mirror reflects the blue laser light emitted from each laser diode toward a predetermined position on the reflective phosphor plate, whereby the reflective phosphor plate emits white light. The beam-shaping lenses are disposed between a different one of the laser diodes and the mirror. The first lens receives the white emitted from the reflective phosphor plate.
