Faculty of Engineering and Information Sciences - Papers: Part A
Well-crystallized Mn3O4-anchored reduced graphene oxide (rGO) nanocomposites have been successfully synthesized via a facile, effective, energy-saving, and scalable microwave hydrothermal technique for potential application as supercapacitor material. Integrating these nanostructures resulted in a strong synergistic effect between the two materials, consequently leading to a hybrid composite with higher specific capacitance compared to the bare Mn3O4 nanoparticles. The results from different sorts of characterization indicate that the Mn3O4 particles were deposited and anchored on graphene sheets. The capacitance value of the rGO(31.6%)–Mn3O4 nanocomposite reached 153 F/g, much higher than that of the bare Mn3O4 (87 F/g) at a scan rate of …

Wavelet Transform Based De-Noising Method For Self Mixing Interferometry Signals, Yuan Sun, Yanguang Yu, Jiangtao Xi
Faculty of Engineering and Information Sciences - Papers: Part A
Self-mixing interferometry (SMI) signals are observed from a laser diode (LD) with optical feedbacks induced by an external target. SMI signals carry information related to both of the target and parameters of the LDs. However, the noise contained in SMI signals greatly degrades the applications of the SMI systems. This paper proposes a wavelet transform based de-noising method which can effectively eliminate noise while keeping an SMI waveform less changed. The proposed method is verified by both simulations and experiments
Parallel Computing Method For Intermodal Shipping Network Design, Zhiyuan Liu, Shuaian Wang, Qiang Meng
Parallel Computing Method For Intermodal Shipping Network Design, Zhiyuan Liu, Shuaian Wang, Qiang Meng
Faculty of Engineering and Information Sciences - Papers: Part A
This study aims to improve the efficiency of design technique for intermodal shipping network design, by virtue of parallel computing system. The existing methods for maritime liner shipping network design are mainly dealing with port-to-port demand. However, a big portion of the customers of a liner shipping company locate in the inland part. Thus, a holistic analysis is necessary to deal with the inland OD pairs, where the transport mode-change from inland transportation to maritime shipping is involved. This paper first reviews a solution method for the conversion of inland OD demand to port-to-port demand. Due to the size of …
Momentum Balance Method And Estimation Of Boundary Shear Stress Distribution, Shu-Qing Yang, Nadeesha Chamini Dharmasiri, Yu Han
Momentum Balance Method And Estimation Of Boundary Shear Stress Distribution, Shu-Qing Yang, Nadeesha Chamini Dharmasiri, Yu Han
Faculty of Engineering and Information Sciences - Papers: Part A
Determination of local boundary shear stress is an important topic in hydraulic engineering. When attempting to determine this from a very thin boundary region, it is a difficult one because it requires special skills and instruments to treat the measured data. With the advent of new equipment, like the acoustic Doppler velocity profilers (ADVP), all the velocity profiles in the primary flow region can be simultaneously measured, and it is necessary to develop a new method to estimate the boundary shear stress using the primary flow data. This paper presents such a method called the momentum balance method (MBM). A …

Purpose: A real-time in vivo dosimetric verification method using metal-oxide-semiconductor field effect transistor (MOSFET) dosimeters has been developed for patient dosimetry in high-dose rate (HDR) intracavitary brachytherapy of nasopharyngeal carcinoma (NPC). Methods: The necessary calibration and correction factors for MOSFET measurements in 192Iridium source were determined in a water phantom. With the detector placed inside a custom-made nasopharyngeal applicator, the actual dose delivered to the tumor was measured in vivo and compared to the calculated values using a commercial brachytherapy planning system. Results: Five MOSFETs were independently calibrated with the HDR source, yielding calibration factors of 0.48 ± 0.007 cGymV. …

Chain-Die Forming, Is It A Right Forming Method To Make Structural Parts Of Motor Vehicles With Uhss Material, Shichao Ding, Yuankun Zhang
Faculty of Engineering and Information Sciences - Papers: Part A
Reducing the body weight of a motor vehicle is one of the most important research approaches in car manufacturing and steel making industries in order to reduce the pollution caused by motor vehicles. In this approach, ultra-high strength steel (UHSS) is developed by steel makers and has been applied more and more to motor vehicles. The UHSS materials have the required strength, but more or less the material's ductility is sacrificed to achieve this target. High strength materials are difficult to form using conventional forming methods. Forming high strength materials to parts effectively and economically is a high priority. Chain-die …
