| 2 | Simulation of Vortex-Induced Vibrations of A Cylinder Using ANSYS CFX显示文摘In this paper, vortex-induced vibrations of a cylinder are simulated by use of ANSYS CFX simulation code. The cylinder is treated as a rigid body and transverse displacements are obtained by use of a one degree of freedom spring damper system. 2-D as well as 3-D analysis is performed using air as the fluid. Reynolds number is varied from 40 to 16000 approx., covering the laminar and turbulent regimes of flow. The experimental results of(Khalak and Williamson, 1997) and other researchers are used for validation purposes. The results obtained are comparable. | Abu Bakar IZHAR Arshad Hussain QURESHI Shahab KHUSHNOOD | 2014 | China Ocean Engineering2014，28，4： | 5 |
| 3 | A Hybrid Quantum Inspired Particle Swarm Optimization and Least Square Framework for Real-time Harmonic Estimation显示文摘The power quality is becoming an extensively addressing aspect of the power system because of the sensitive operation of the smart grid, awareness of power quality, and the equipment of modern power systems. In this paper, we have conceived a new hybrid Quantum inspired particle swarm optimization and least square(QPSO-LS) framework for real-time estimation of harmonics presented in time-varying noisy power signals. The technique has strong, robust, and reliable search capability with powerful convergence properties. The proposed approach is applied to various test systems at different signal to noise ratio(SNR) levels in the presence of uniform and Gaussian noise. The results are presented in terms of precision, computation time, and convergence characteristics. The computation time decreases by 3-5 times as compared to the existing algorithms. The technique is further authenticated by estimating harmonics of real-time current or voltage waveforms, obtained from light emitting diode(LED) lamp and axial flux permanent magnet synchronous generator(AFPMSG). The results demonstrate the superiority of QPSO-LS over other methods such as LS-based genetic algorithm(GA), particle swarm optimization(PSO), bacterial foraging optimization(BFO), artificial bee colony(ABC), and biogeography based optimization with recursive LS(BBO-RLS) algorithms, in terms of providing satisfactory solutions with a significant amount of robustness and computation efficiency. | Abu Bakar Waqas Muhammad Mansoor Ashraf Yasir Saifullah | 2021 | Journal of Modern Power Systems and Clean Energy2021，9，6： | 3 |

| 5 | Analysis on fused deposition modelling performance显示文摘Fused deposition modelling (FDM) is one of rapid prototyping (RP) technologies which uses an additive fabrication approach.Each commercially available FDM model has different types of process parameters for different applications.Some of the desired parts require excellent surface finish as well as good tolerance.The most common parameters requiring setup are the raster angle,tool path,slice thickness,build orientation,and deposition speed.The purpose of this paper is to discuss the process parameters of FDM Prodigy Plus (Stratasys,Inc.,Eden Prairie,MN,USA).Various selected parameters were tested and the optimum condition was proposed.The quality of the parts produced was accessed in terms of dimensional accuracy and surface finish.The optimum parameters obtained were then applied in the fabrication of the master pattern prior to silicone rubber moulding (SRM).These parameters would reduce the post processing time.The dimensional accuracy and surface roughness were analyzed using coordinate measuring machine (CMM) and surface roughness tester,respectively.Based on this study,the recommended parameters will improve the quality of the FDM parts produced in terms of dimensional accuracy and surface roughness for the application of SRM. | Nur Saaidah Abu BAKAR Mohd Rizal ALKAHARI Hambali BOEJANG | 2010 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2010，11，12： | 3 |
| 6 | Interference-Aware Multipath Routing Protocol for QoS Improvement in Event-Driven Wireless Sensor Networks显示文摘The existing multipath routing protocols for wireless sensor networks demonstrate the efficacy of traffic distribution over multiple paths to fulfill the Quality of Service (QoS) requirements of different applications.However,the performance of these protocols is highly affected by the characteristics of the wireless channel and may be even inferior to the performance of single-path approaches.Specifically,when multiple adjacent paths are being used concurrently,the broadcast nature of wireless channels results in inter-path interference which significantly degrades end-to-end throughput.In this paper,we propose a Low-Interference Energy-efficient Multipath Routing protocol (LIEMRO) to improve the QoS requirements of event-driven applications.In addition,in order to optimize resource utilization over the established paths,LIEMRO employs a quality-based load balancing algorithm to regulate the amount of traffic injected into the paths.The performance gain of LIEMRO compared to the ETX-based single-path routing protocol is 85%,80%,and 25% in terms of data delivery ratio,end-to-end throughput,and network lifetime,respectively.Furthermore,the end-to-end latency is improved more than 60%. | Marjan Radi Behnam Dezfouli Kamalrulnizam Abu Bakar Shukor Abd Razak Mohammad Ali Nematbakhsh | 2011 | Tsinghua Science and Technology2011，16，5： | 3 |

| 10 | Vital roles of stem cells and biomaterials in skin tissue engineering显示文摘Tissue engineering essentially refers to technology for growing new human tissue and is distinct from regenerative medicine. Currently, pieces of skin are already being fabricated for clinical use and many other tissue types may be fabricated in the future.Tissue engineering was first defined in 1987 by the United States National Science Foundation which critically discussed the future targets of bioengineering research and its consequences. The principles of tissue engineering are to initiate cell cultures in vitro, grow them on scaffolds in situ and transplant the composite into a recipient in vivo. From the beginning, scaffolds have been necessary in tissue engineering applications. Regardless, the latest technology has redirected established approaches by omitting scaffolds. Currently, scientists from diverse research institutes are engineering skin without scaffolds. Due to their advantageous properties, stem cells have robustly transformed the tissue engineering field as part of an engineered bilayered skin substitute that will later be discussed in detail. Additionally, utilizing biomaterials or skin replacement products in skin tissue engineering as strategy to successfully direct cell proliferation and differentiation as well as to optimize the safety of handling during grafting is beneficial. This approach has also led to the cells' application in developing the novel skin substitute that will be briefly explained in this review. | Abu Bakar Mohd Hilmi Ahmad Sukari Halim | 2015 | World Journal of Stem Cells2015，7，2： | 2 |

| 13 | Toxicity evaluation of ZnO and TiO_2 nanomaterials in hydroponic red bean(Vigna angularis) plant:Physiology, biochemistry and kinetic transport显示文摘The toxicity and kinetic uptake potential of zinc oxide(Zn O) and titanium dioxide(TiO_2)nanomaterials into the red bean(Vigna angularis) plant were investigated. The results obtained revealed that Zn O, due to its high dissolution and strong binding capacity, readily accumulated in the root tissues and significantly inhibited the physiological activity of the plant. However, TiO_2 had a positive effect on plant physiology, resulting in promoted growth. The results of biochemical experiments implied that Zn O, through the generation of oxidative stress, significantly reduced the chlorophyll content, carotenoids and activity of stress-controlling enzymes. On the contrary, no negative biochemical impact was observed in plants treated with TiO_2. For the kinetic uptake and transport study, we designed two exposure systems in which Zn O and TiO_2 were exposed to red bean seedlings individually or in a mixture approach. The results showed that in single metal oxide treatments, the uptake and transport increased with increasing exposure period from one week to three weeks.However, in the metal oxide co-exposure treatment, due to complexation and competition among the particles, the uptake and transport were remarkably decreased. This suggested that the kinetic transport pattern of the metal oxide mixtures varied compared to those of its individual constituents. | Shanaz Jahan Yatimah Binti Alias Ahmad Farid Bin Abu Bakar Ismail Bin Yusoff | 2018 | Journal of Environmental Sciences2018，30，10： | 2 |
