| 1 | Solving traveling salesman problems using generalized chromosome genetic algorithm显示文摘Generalized chromosome genetic algorithm (GCGA) was proposed for solving generalized traveling salesman problems (GTSP) as reported in the authors’ earlier work. Theoretically, the GCGA could also be used to solve the classical traveling salesman problem (CTSP), which has not been reported by others. In this paper, the generalized chromosome characteristics are analyzed and the feasibility for consistently solving the GTSP and CTSP is verified. Numerical experiments show the advantages of the GCGA for solving a large- scale CTSP. | Jinhui Yang Chunguo Wu Heow Pueh Lee Yanchun Liang | 2008 | Progress in Natural Science:Materials International2008，18，7： | 15 |

| 3 | 非均匀温度场下涡旋压缩机涡旋盘数值仿真研究显示文摘基于热应力场耦合建立了汽车涡旋压缩机涡旋盘有限元模型,涡旋齿载荷边界条件设置为流场离散,在气体压力载荷单独作用、温度场载荷单独作用以及两者耦合作用这三种情况下,对涡旋盘进行受力分析和变形分析,讨论不同主轴转角的涡旋齿的刚度和强度,最后得到涡旋齿的变形规律和应力分布。分析结果表明:当涡旋盘压缩腔运动到排气孔位置时,涡旋盘处于变形与应力最大的状态,热变形是影响涡旋盘整体变形的主要因素。 | 羊玢 郑庆乾 汤勇 谢继鹏 Lee Heow Pueh | 2017 | 液压与气动2017，41，2： | 7 |
| 4 | An experimental study on shock wave mitigation capability of polyurea and shear thickening fluid based suspension pads显示文摘The present experimental study investigates shock wave mitigation capability of potentially new personal protective equipment(PPE) suspension pads made from polyurea and shear thickening fluid(STF).The shock tube test results show that when placed behind Twaron fabric systems with thickness ranging from 2 mm to 18 mm, the replacement of conventional flexible foam pad with STF and STF-infused foam pads with the same thickness of 20 mm greatly reduces the normalized peak pressure(by about 72% for each pad). However, this benefit is partially offset by a large increase in the normalized impulse(by about78% for the STF pad and 131% for the STF-infused foam pad) which may cause the shock wave mitigation performance of these two pads to become less effective. Interestingly, the use of 4 mm thick polyurea pad can greatly reduce the normalized peak pressure and impulse as well(by about 74% and 49%, respectively). These results reveal that among the potentially new suspension pads tested, the polyurea pad displays the best shock wave mitigation performance. Therefore, polyurea has potential for use as a suspension pad in personal protective equipment requiring shock wave mitigation capability such as fabric ballistic vests, bomb suits and combat helmets. | Andi Haris Heow Pueh Lee Vincent Beng Chye Tan | 2018 | Defence Technology(防务技术)2018，14，1： | 5 |

| 6 | 面部碰撞对行人创伤性脑损伤影响的生物力学研究显示文摘为预测和评判行人面部碰撞对创伤性脑损伤机理及生物力学响应,结合计算机断层扫描(CT)和磁共振(MRI)医学成像技术,建立符合中国人体特征的50百分位头颈部几何模型和有限元模型。有限元模型中颅骨与脑之间的相对运动采用切向滑动边界条件,摩擦系数定义为0.2,模拟鼻骨斜碰撞、鼻外侧软骨正面碰撞、牙齿正面碰撞、下颌骨碰撞和颧骨外侧斜碰撞等5种典型面部碰撞交通事故场景,探讨应力波在颅骨和脑内传播路径,得到颅内压力、von Mises等效应力和剪切应力等生物力学响应参数分布规律。结果显示,鼻骨斜碰撞颅内压力峰值为236.7 k Pa,von Mises应力为25.97 k Pa,超过了大脑耐受阈值;颧骨外侧斜碰撞最大横向剪切应力分别为14.56 k Pa和-18.07 k Pa,促使脑组织产生了较大的剪切变形,存在严重脑损伤风险。结论表明:面部碰撞的位置和方向是导致面部骨折严重程度的关键因素,面骨骨折的位置决定创伤性脑损伤的部位,面骨骨折都带有一定程度的创伤性脑损伤;头部受到冲击时,面部结构能够吸收大量的冲击能量来保护大脑,降低颅脑损伤的风险。 | 羊玢 曹立波 李鹏 胡敏 肖峰 袁云康 梅永存 Lee Heow Pueh | 2016 | 中国生物医学工程学报2016，35，1： | 4 |

| 20 | Studies on the sound absorption and transmission loss performances of wood-based, natural and wastematerials显示文摘The sound absorption and sound transmission loss performances of the natural woods,hard and soft processed woods with attachment of the various natural orwastematerials were investigated in the present study using impedance tube with American Society for Testing Material(ASTM)standards.The sound absorption performances of all natural and all hard processed woods were very poor.It was found that filter mat made by the coconut fibre was the best material for sound absorption improvement of the hard processed woods.The sound absorption performance of the soft processed wood(cork)was better than all natural and all hard processed woods.Among all tested woods,it was found that the cork with attached tea bag made by corn fibre is the best selection for sound absorption application.The transmission loss performances of all natural woods were good.The effects of various materials on the transmission loss performances of all hard processed woods were not very significant.For cork with and without attachment of various materials,their transmission loss performances were not as good as the hard processed woods.Among all tested woods,it was found that Pterocarpus soyauxii and Quercus spp.(natural woods)are the best woods to be used in those applications when prevention of sound transmission is needed.It is recommended that cork is the best wood to be used in those applications where sound absorption and prevention of sound transmission are needed at the same time due to its good sound absorption performance while its ability on prevention of the sound transmission is also acceptable. | Hsiao Mun Lee Wensheng Luo Jinlong Xie Guilin Wen Heow Pueh Lee | 2021 | Acta Mechanica Sinica2021，37，5： | 0 |
