Abstract Novel concepts are essential for design innovation and can be generated with the aid of data stimuli computers. However, current generative algorithms focus on diagrammatic or spatial that either too abstract to understand detailed early phase exploration. This paper explores uses pre-trained transformers (GPT) natural language concept generation. Our experiments involve use GPT-2 GPT-3 different creative reasonings in tasks. Both show reasonably good performance verbal

This paper focused on understanding fundamental issues leading in polymer composites and their effect dimensional accuracy manufactured components. Unlike most existing work, which use simplified geometrical and/or material models or merely cooldown process, three coupled...

Objective: To explore the application value of surface respiratory muscle electromyography and its ratio to tidal volume in assessment airway hyperresponsiveness bronchial asthma patients. Methods: A case-control study was conducted retrospectively analyze data 29 patients who visited outpatient department medicine First Affiliated Hospital Guangzhou Medical University from October 2015 May 2017 27 non-asthmatic subjects were recruited as control group.Changes [parasternal...
We present a design sensitivity analysis, which supports the shape optimization of tool used in thermoset composite manufacturing. The method provides systematic way to predict optimal geometry that leads minimum difference between desired and final shapes manufactured part. process is formalized by integrating modeling, numerical into single framework. modeling based on transient coupled thermo-chemo-viscoelastic finite element scheme, accurately capturest he evolution residual stresses...
Abstract The aim of this work is to investigate the acoustoelastic effect in a thermoplastic polymer (polyamide 6) under uniaxial compression using ultrasonic waves (longitudinal and shear). acoustic velocities varied linearly, as expected, when small strains or stresses were applied, from which Murnaghan coefficients obtained for first time type polymer. This relationship changed be nonlinear above critical strain at about 0.7%. behaviour has already been observed polymers tensile tests but...
The ultrasonic phased array total focusing method (TFM) has the advantages of high imaging resolution and sensitivity to small defects. However, it a long time cannot realize near-distance defect imaging, which limits its application for industrial detection. A sparse-TFM algorithm is adopted in this work solve problem regarding rapid near- distance defects thin plates. Green’s function reconstructed through cross-correlation diffuse full matrix captured by array. recovers scattering...
Abstract We present the temporal and spatial characterization of X-ray sources (at ~1 keV) driven by a 200 TW, 30 fs, 800 nm laser pulse on SILEX-I facility at Research Center Laser Fusion. For copper foil interaction with intensity between 6 × 10 18 W/cm 2 3 19 , images show cone-like jet structures. While yield X-rays is strongly dependent intensity, plasma expansion length weakly open angle not correlated to intensity. The formation structure attributed transverse confine self-induced...
This paper describes an imaging method for near-field defect detection in aluminum plates based on Green's function recovery and application of instantaneous phase coherence weighting factors. The directly acquired acoustic information defects is usually obscured by the nonlinear effects due to physical limitation acquisition system. Using diffuse field recover can effectively retrieve early time information. However, averaging operations finite number this process produces imperfect result....
This paper provides a comprehensive review of the NTIRE 2024 challenge, focusing on efficient single-image super-resolution (ESR) solutions and their outcomes. The task this challenge is to super-resolve an input image with magnification factor x4 based pairs low corresponding high-resolution images. primary objective develop networks that optimize various aspects such as runtime, parameters, FLOPs, while still maintaining peak signal-to-noise ratio (PSNR) approximately 26.90 dB...
Abstract High-resolution ultrasonic imaging for defects in anisotropic multilayer carbon fiber reinforced polymers (CFRPs) is challenging because of the severe attenuation and low signal-to-noise ratio (SNR) echoes. The existing delay-multiply-and-sum (DMAS) beamforming outperforms delay-and-sum (DAS) resolution, but with high computational complexity energy loss. This paper presents a novel delay-sum-and-square (DSAS) algorithm. It takes full advantage spatial coherence captured data...
