Background The demand for healthcare is increasing globally, with notable disparities in access to resources, especially Asia, Africa, and Latin America. rapid development of Artificial Intelligence (AI) technologies, such as OpenAI’s ChatGPT, has shown promise revolutionizing healthcare. However, potential challenges, including the need specialized medical training, privacy concerns, language bias, require attention. Methods To assess applicability limitations ChatGPT Chinese English...
Abstract. Relying on geological data to construct 3D models can provide a more intuitive and easily comprehensible spatial perspective. This process aids in exploring underground structures evolutionary processes, providing essential assistance for the exploration of resources, energy development, engineering decision-making, various other applications. As one methods modeling, multipoint statistics effectively describe reconstruct intricate geometric shapes nonlinear bodies. However,...
Neural Machine Translation (NMT) has shown great advantages and is becoming increasingly popular. However, in practice, NMT often produces unexpected translation failures its translations. While reference-based black-box system testing been a common practice for quality assurance during development, an critical industrial named in-vivo testing, exposes unseen types or instances of when real users are using deployed system. To fill the gap lacking test oracles systems, we propose new...
Despite getting widely adopted recently, a Neural Machine Translation (NMT) system is often found to produce translation failures in the outputs. Developers have been relying on in-house testing for quality assurance of NMT. This methodology requires human-constructed reference translations as ground truth (test oracle) example natural language inputs. The has shown benefits quickly enhancing an NMT early development stages. However, industrial settings, it desirable detect without reliance...
Neural Machine Translation (NMT) has been widely adopted recently due to its advantages compared with the traditional Statistical (SMT). However, an NMT system still often produces translation failures complexity of natural language and sophistication in designing neural networks. While in-house black-box testing based on reference translations (i.e., examples valid translations) a common practice for quality assurance, increasingly critical industrial practice, named in-vivo testing,...
In mathematics, homogenization theory considers the limitations ofthe sequences of problems and their solutions when a parametertends to zero. This parameter is regarded as ratio thecharacteristic size between micro scale macro scale.So what considered sequence in fixed domainwhile characteristic tends But inthe real physics or engineering situations, amedium can not be changed. process ofhomogenization, it which becomes largerand larger infinity. We observe that homogenizationin equivalent...
Abstract The fluid-structure interaction (FSI) program were used to simulate the condition that inflated membrane structure transport process in incoming flow. A comparison between results from numerical simulation and ground test was validate computational method. Due analysis of flow field structure’s deformation, law force variation during FSI discussed, causes deformation instability problems preliminary discussed. Possible ways reduce sensitivity envelope caused by constraint position...
Diamond back wing is subjected to large deformation while gliding, which significantly changes characteristics of the lift as well static stability. For this reason, conventional rigid aircraft assumption cannot meet requirements aerodynamic analysis such aircrafts for accuracy. In paper, based on CFD/CSD methods, aeroelasticity a small diameter bomb with diamond was studied. The results showed that aeroelastic effects cause slope line drop by 21% and centre move backwards 1.5% body length,...
