The computing device provides at least the one or more features as inputs to one or more machine learning models to determine one or more predictions of execution times. The computing device determines an optimum execution architecture based on the one or more predictions of execution times. The computing device distributes portions of the design for simulation based on the optimum execution architecture. In some embodiments, one or more machine learning models are trained to generate outputs for predicting an optimal parallel execution architecture for simulation of a design.

Abstract: In some embodiments, a non-transitory computer-readable medium is provided. The computer-readable medium has logic stored thereon that, in response to execution by one or more processors of a computing system, cause the computing system to perform actions for deriving a fabrication model for a fabrication system using an inverse design process. The actions include determining a test design for a test physical device, measuring performance of an instance of the test physical device fabricated by the fabrication system using the test design to determine an as-fabricated performance metric, optimizing the test design using a first loss function based on differences in a simulated performance metric of the test design and the as-fabricated performance metric to determine an as-fabricated design, and optimizing a fabrication model using a second loss function based on differences between the test design and the as-fabricated design.

Abstract: An object to provide a photonic crystal capable of resonating light at more resonant frequencies within a particular frequency range. A plurality of photonic crystal structure formation bodies each including a plate-like member in which cyclic refractive index distribution is formed are provided so as to be spaced apart from each other in the thickness direction of the plate-like member, and the respective refractive index distributions of the plurality of photonic crystal structure formation bodies are set such that: at least one of the plurality of photonic crystal structure formation bodies resonates with light having at least two frequencies within the frequency range; and the two frequencies are different from resonant frequencies of at least one of the other photonic crystal structure formation bodies.

Abstract: An organic light emitting device is described, having an OLED including an anode, a cathode, and at least one organic layer between the anode and cathode. At least a portion of an electrode surface includes a plurality of scattering structures positioned in a partially disordered pattern resembling nodes of a two dimensional lattice. The scattering structures are positioned around the nodes of the two dimensional lattice with the average distance between the position of each scattering structure and a respective node of the lattice is from 0 to 0.5 of the distance between adjacent lattice nodes. A method of manufacturing an organic light emitting device and a method of enhancing the light-extraction efficiency of an organic light emitting device are also described.
