| 5 | Effect of Al_(2)O_(3) Nanoparticle on Cavitation Strengthening of Magnesium Alloys显示文摘In order to study the effect of Al_(2)O_(3) nanoparticles in the cavitation-based strengthening process of magnesium alloys,the impact of a micro-jet generated by bubble collapse has been considered.The strengthening mechanism is based on the transfer of the energy of cavitation due to bubble collapse to Al_(2)O_(3) particles,which then undergo collision with the surface of the sample.The hardness,surface morphology,element content and chemical state of the strengthened samples have been analyzed by microhardness tests,SEM(scanning electron microscopy)and XPS(X-ray photoelectron spectroscopy)techniques.The results show that:after 5 min of strengthening,nanoparticles can be found on the surface of the sample through SEM.Combined with XPS tests,the content of Al_(2)O_(3) in the sample can be significantly increased,indicating that Al_(2)O_(3) particles penetrate into the surface and increase its hardness by 29.1 HV. | Lei Liu Chuanhui Huang Xinghua Lu Ping Yu Longhai Li Huafeng Guo | 2021 | Fluid Dynamics & Materials Processing2021，17，2： | 1 |

| 7 | The domain structure and polarization retention properties of PT/PZT/PT ferroelectric thin film显示文摘The highly oriented perovskite-phase PT/PZT/PT ferroelectric thin film was pre- pared by sol-gel method. The domain structures and polarization retention proper- ties were investigated by scanning force microscopy. The amplitude and phase images of piezoresponse show complex various contrasts of dark, bright and gray. The complex variation of contrast in piezoresponse images results from the per- plexing orientation of grains and arrangement of domains in the ferroelectric films. The bright and dark areas in phase images correspond to top-to-bottom and bot- tom-to-top polarization oriented c-domain, respectively. The gray areas are c-domains with the polarization vector deviating from the direction normal to the film plane. The surface potential images of EFM are bright contrast, which is due to positive charges trapped on the film surface after being polarized by positive volt- age. And the brighter contrast is obtained from the higher electric field. The time-dependent surface potential images and line potential profiles show that the potential decays with time. And the decay in the region polarized by higher electric field is faster, especially at 15 min. This indicates that the polarization retention is related to the polarized electric field. Better retention properties may be obtained from a proper polarized electric field. | WANG LongHai Yu Jun ZHAO SuLing ZHENG ChaoDuan WANG YunBo GAO JunXiong | 2007 | Science China(Technological Sciences)2007，50，2： | 0 |
| 8 | Recommendation Algorithm Based on Probabilistic Matrix Factorization with Adaboost显示文摘A current problem in diet recommendation systems is the matching of food preferences with nutritional requirements,taking into account individual characteristics,such as body weight with individual health conditions,such as diabetes.Current dietary recommendations employ association rules,content-based collaborative filtering,and constraint-based methods,which have several limitations.These limitations are due to the existence of a special user group and an imbalance of non-simple attributes.Making use of traditional dietary recommendation algorithm researches,we combine the Adaboost classifier with probabilistic matrix factorization.We present a personalized diet recommendation algorithm by taking advantage of probabilistic matrix factorization via Adaboost.A probabilistic matrix factorization method extracts the implicit factors between individual food preferences and nutritional characteristics.From this,we can make use of those features with strong influence while discarding those with little influence.After incorporating these changes into our approach,we evaluated our algorithm’s performance.Our results show that our method performed better than others at matching preferred foods with dietary requirements,benefiting user health as a result.The algorithm fully considers the constraint relationship between users’attributes and nutritional characteristics of foods.Considering many complex factors in our algorithm,the recommended food result set meets both health standards and users’dietary preferences.A comparison of our algorithm with others demonstrated that our method offers high accuracy and interpretability. | Hongtao Bai Xuan Li Lili He Longhai Jin Chong Wang Yu Jiang | 2020 | Computers, Materials & Continua2020，，11： | 0 |
| 9 | System Energy and Efficiency Analysis of 12.5 W VRFB with Different Flow Rates显示文摘Vanadium redox flow battery(VRFB)is considered one of the most potential large-scale energy storage technolo-gies in the future,and its electrolyte flow rate is an important factor affecting the performance of VRFB.To study the effect of electrolyte flow rate on the performance of VRFB,the hydrodynamic model is established and a VRFB system is developed.The results show that under constant current density,with the increase of electrolyte flow rate,not only the coulombic efficiency,energy efficiency,and voltage efficiency will increase,but also the capacity and energy discharged by VRFB will also increase.But on the other hand,as the flow rate increases,the power of the pump also increases,resulting in a decrease in system efficiency.The energy discharged by the system does not increase with the increase in flow rate.Considering the balance between efficiency and pump power loss,it is experimentally proved that 120 mL·min-1 is the optimal working flow rate of the VRFB system,which can maximize the battery performance and discharge more energy. | Kehuan Xie Longhai Yu Chuanchang Li | 2023 | Energy Engineering2023，120，12： | 0 |
| 10 | Dual attention autoencoder for all-weather outdoor lighting estimation显示文摘Accurate outdoor illumination estimation is not easy due to extremely complicated sky appearance and the mutual interference of the sun and sky. In view of these challenges, we present a new deep approach for the estimation of all-weather outdoor illumination. The key to our approach is a novel dual attention autoencoder(DAA) with two independent branches to compress the sun and sky lighting information from an input HDR panorama, respectively. This enables more accurate lighting estimation as evidenced by our experiments since the mutual interference between the sun and sky can be precluded effectively. In DAA,we design the adaptive feature pyramid and the attention module to promote its accuracy in compression.We further develop a sun-sky predictor, a masked network, to learn the sun and sky lighting conditions from an Fo V-limited image. Comprehensive qualitative and quantitative experiments verify the effectiveness of our proposed approach and show its superiority over the state of the arts. | Piaopiao YU Jie GUO Longhai WU Cheng ZHOU Mengtian LI Chenchen WANG Yanwen GUO | 2021 | Science China(Information Sciences)2021，64，11： | 0 |
