We present a framework for fast synthesizing indoor scenes, given room geometry and list of objects with learnt priors. Unlike existing data-driven solutions, which often learn priors by co-occurrence analysis statistical model fitting, our method measures the strengths spatial relations tests complete randomness (CSR), learns discrete based on samples ability to accurately represent exact layout patterns. With priors, achieves both acceleration plausibility partitioning input into disjoint...

The crystal structure of poly(3-hexylthiophene) (P3HT) has been studied by first-principles calculations based on density functional theory. generalized gradient approximation is employed and van der Waals interactions are treated accurately the recently proposed local atomic potential approach. A variety different models were tested, model having lowest energy a noninterdigitated an orthorhombic cell with $a$ $=$ 17.2 \AA{}, $b$ 7.7 $c$ 7.8 where $a$, $b$, lengths lattice vectors...

In this work, a novel approach that combines artificial neural networks (ANNs) and polynomial modeling to efficiently model the behavior of nonlinear RF devices is introduced. Utilizing strengths ANNs in knowledge retention transfer, proposed effectively incorporates new operational states such as different dc biases, frequencies, dies, into existing models. This adaptive capability, addition dynamic sampling techniques only capture crucial characteristics across various states,...

A vertically integrated one transistor memory cell, in which an n-p-n bipolar access is merged with a p-n-p storage capacitor, based on the wide-bandgap semiconductor silicon carbide (SiC), results greatly reduced thermal generation rate. Extrapolation of charge recovery data obtained at elevated temperatures suggests room temperature time over 10/sup 6/ years.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Abstract This paper proposes a novel approach for modeling the nonlinear behavior of microwave devices, with particular focus on addressing challenging problem compound semiconductor transistors under large‐signal excitation. The utilizes knowledge‐based neural network (KBNN) to construct frequency‐domain behavioral model transistor, which maps incident and scattered waves from coarse fine in cases where fails match new device. network‐based method aims achieve better alignment between...

Recent studies show increasing demands and interests in automatically generating layouts, while there is still much room for improving the plausibility robustness. In this paper, we present a data-driven layout framework without model formulation loss term optimization. We achieve organize priors directly based on samples from datasets instead of sampling probabilistic models. Therefore, our method enables expressing mathematically inexpressible relations among three or more objects....
