Aspects of the invention include systems and methods configured to provide hierarchical circuit designs that makes use of a color decomposition of library cells having boundary-aware color selection. A non-limiting example computer-implemented method includes placing a plurality of shapes within a hierarchical level of a chip design. The plurality of shapes can include a top boundary shape, a bottom boundary shape, one or more center boundary shapes, and one or more internal shapes. A hierarchical hand-off region is constructed by pinning the top boundary shape to a first mask, pinning the bottom boundary shape to a second mask, and pinning the one or more center boundary shapes to a same mask. The same mask is selected from one of the first mask and the second mask.

Each panel includes a first surface configured to face an exterior environment of a building and a second surface configured to face an interior of the building; at least one perforation extending between the first and second surface; rail connection elements configured to attach the panel to a rail; and interlocking elements configured for panel-to-panel assembly. The panels are configured to be assembled by a single person. The interlocking elements are configured to connect one panel of the plurality of panels to another panel forming a unit of connected panels without using additional hardware.

Processes for optimizing the geometry of a blade for use in a propeller are disclosed. In one exemplary process, an optimization routine that generates new blade geometries based on structural parameters and calculates performance parameters of each blade geometry, including aerodynamic performance parameters, farfield acoustic parameters, and/or electrical power requirements to operate a propeller having the blade geometry, is performed. The optimization routine receives design parameters and weightings from a user and can use one or more surrogate algorithms to map a design space of the weighted values of the design parameters to find their local minima. The optimization routine then determines an optimized blade geometry using a gradient-based algorithm to generate new blade geometries to explore the minima until the weighted values of the design parameters converge at an optimized blade geometry representing the global minima of the design space.

A system allows a user to create new designs for apparel and preview these designs before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. The system swaps garments in a digital asset to garments that are designed using the system. The wear pattern is created by a laser using a laser input file. Generating the preview image comprises combining first and second contributions to obtain a combined value for a pixel at the pixel location of the preview image.
