Authors: Wei-wen Mao , Shi-wei He 
Published: October 2020

Abstract
China’s high-speed rail is already at the forefront of the world. The layout of the high-speed railway bus terminal is not only related to the construction of the high-speed rail network, but also a major strategic decision for urban development, and it is related to another leap forward development opportunity for the city. At present, the evaluation plan of the railway hub passenger transport system is not perfect, because many aspects of the plan are difficult to quantify, and it is prone to inaccurate judgments of factors that lead to more one-sided conclusion. This paper establishes a comparatively comprehensive set of layout evaluation indicators, advocates selecting or creating a corresponding index construction index system according to the characteristics of the evaluation target, and combines the entropy weighting method and the TOPSIS method to form a new rating method and applies it to the layout evaluation.

Abstract
This study reported the tribological evaluation of polyolester based lubricant synthesised from waste feedstock. The transesterification process was adopted for the formulation of lubricant from waste mango seed kernel oil. The polyols used in this formulation are neopentyl glycol, trimethylolpropane and pentaerythritol. The tribological investigation was conducted using four ball tribometer as per ASTM D4172. The frictional and wear behavior of vegetable oil-based polyolester was analysed in addition to the wear morphology of investigated balls. The results indicated that the average frictional torque and mean wear diameter of pentaerythritol ester of waste mango seed oil was 0.12 Nm and 0.403 mm respectively and also found that the pentaerythritol ester showed improved tribological results as compared with other polyolesters say neopentyl glycol ester and trimethylolpropane ester of waste mango seed oil. The waste mange seed oil is found suitable candidate for the formulation of polyolester based sustainable lubricant.

Authors: Kumar K. , Arul S. 
Published: October 2020

AbstractMetals and their alloys have been widely used in all aspects of science and engineering. However the science of nanotechnology is driving newer demands and requirements for better performance of existing materials and also at a higher level of precision. This is naturally presenting complicated demands on the surface of these metals with a need for surface modification. In the present scenario it is noteworthy that nano scaled particle coatings enhances the mechanical properties in the metals rather than the macro or micro sized particles. Hence an attempt was made to characterize the mechanical properties of cuprous oxide nano particles coated spur gear (Mild Steel). The mechanical properties such as tensile, hardness and corrosion (salt spray) were experimentally investigated at ambient condition. A deep compression had been made between the coated and uncoated gear. The results reveal that the coated gear shows better performance compared with uncoated gears.

Abstract
Thermal barrier coatings (TBC) are made from alloys such as super alloys, titanium alloys and advanced steel materials. These alloys are widely used to make parts of aircraft, and these parts are used for in corrosive environments and high temperature operations. TBCs are therefore miserably needed to improve fatigue life, creep strength and corrosion resistance of these alloys. Thermal barrier coating consists of a bond coat and a top coat. The behaviour of the coating, such as oxidation resistance, hardness, microstructure and thermal oxide formation, depends on the coating technique and the bond and top coating materials. Therefore, an attempt has been made in this paper to review recent research on the Thermal Barrier Coating Behavior. Most researchers used NiCoCrAlY as a bond coat and YSZ as a top coat. HVOF and plasma spray techniques were found to be effective than other techniques such as Electron beam physical vapor deposition in this review.

Published: October 2020

AbstractAnti-roll bars are the suspension system component in automobiles that are used to control the body roll effect. They have a strong impact on the handling functions of the engine. The design effects of the anti-roll bar are normal in different vehicles and the study is mandatory for each design change. Finite Element Analysis (FEA) is used for an accurate study of the anti-roll bar style. The finite element analysis is carried out in ANSYS. The paper comprises of pre-processing, evaluating, post-processing, and using the work bench to interpret the FEA results. Be that as it may, because of a high number of rehashed plans looks at, deciphering time and cost issues related with the utilization of general FEA bundle projects may create critical inconveniences in utilizing these bundle projects to perform against move bar structure examination. Vibration characteristics such as typical set vibration levels and frequency are varied within the automotive environment. Even if an automobile is driven, the random excitations from road inputs and intermittent vibrations from engine firing are felt by its components and structures. It can sometimes cause problems with reliability if the construction of the components is often not completely evaluated.

Abstract
The experimental work to boost forced heat transfer performance in an Al2O3, SiC-Water+ ethylene glycol nanofluid radiator was discussed in this paper. In this analysis, different volume fractions of nanofluids in the range of 0.01 to 0.1 percent were prepared and sonicated for 2 hours using an ultrasonic sonicator to achieve stable suspension with the incorporation of Al2O3, Sic nanoparticles into the water. The maxium-performable heat transfer was found to be 50 percent higher than water at a fraction of 0.1 per cent. The effective thermal conductivity of the nanofluid is increased with increased particle concentration, which helps to boost radiator heating efficiency. The rate of heat flow ranges from 3 to 12 lpm. It is noted that the efficiency of heat transfer has increased with an increase in flow rate.

Published: October 2020

Abstract
Grinding plays an essential role in obtaining high dimensional accuracy and surface finish. Three types of work pieces were used with different ratios of SiC (1%,2%,3%). When the composition of SiC increases, the G-ratio decreases. This type of material is highly used in aerospace applications due to its low density and good wear and corrosion resistance. It is genuinely believed that Al-SiC has tremendous potential for application in the aerospace industry. A critical role is played by grinding in achieving good surface finish and improved dimensional accuracy. Therefore, a strategy to improve the grinding rate and surface finish is important for economic production. In this research, the various grinding ratio was found out and results show that G-ratio is high when coolant is used and G-ratio is low when coolant is not used.

Abstract
Selecting optimal and proper cutting parameters for achieving desired results in the AWJ process is a demanding task. Therefore, the main contribution of this work is to apply a new reliable hybrid WCMFO algorithm for process optimization in the AWJ process. Based on the box-behnken design technique, 17 experimental runs were conducted and quadratic model for surface roughness was developed to fit with experimental data. Then, the WCMFO algorithm is implemented in the consideration of surface roughness as a fitness function. The key advantage of this algorithm is that it does not accumulate to any local optima, and the existence of a hybrid algorithm allows it to store the best solutions available so far. The predicted optimal settings were verified through confirmatory experiments, and the results validated.

Published: October 2020

Abstract
The oil-based lubricating system tends to produce high cutting temperatures owning to the low cooling capability of oil lubricants. The addition of lubricating additives in nanoscale could increase the tribological and lubrication performance of the water-based lubricants. In this work, nano CuO particle-filled water-based lubricants as cutting fluids were developed using ultrasonication process. The Thermophysical Properties of synthesized nano filled water-based lubricant was tested and analyzed. The tribological characteristics were fairly investigated using four-ball and pin on disc apparatus testing units. The results indicated that nano CuO filled water-based lubricant shows enhanced tribological performance in terms of coefficient of friction (COF) and wear scar diameter (WSD) compared with base coolant. The superior performance of CuO filled water-based lubricant was credited to the detail that CuO nanoparticle additives arrived the rubbing interface and made a tribo-thin layer of CuO. Water-based lubricant showed the highest surface deformation compared to nano-based lubricants which indicate that the damage was due to adhesive wear.

Published: October 2020

Abstract
The effect of retrogression re-aging treatment (RRA) on the corrosion behavior of 7055 Al-Zn-Mg alloy was studied in this paper. Results provided that corrosion resistance could be greatly improved by RRA. After the RRA treatment, the isolated precipitates occurred on grain boundaries (GBs) and the low angle grain boundaries (LAGBs) presented a larger fraction compared to that of single-stage peaking aging treatment. The samples after RRA treatment also show better corrosion resistance than that of single-stage peak aging treatment. In addition, of the electrochemical impedance spectroscopy (EIS) analysis showed that the impedance spectrum was consisted of semi-infinite layer diffusion impedance and stagnant Weber impedance. The semi-infinite layer diffusion impedance corresponded to a limited retention layer on the electrode surface while the Weber impedance represented a stagnant layer of corrosion products generated by the anode branches. The aluminum alloy after RRA treatment achieved higher Rf and low Cf, Cp values and its corrosion current density was ten times smaller compared to the single-stage peak aging samples with the 10% hardness losing.

Published: October 2020

Abstract
Previous studies on computer aided detection/diagnosis (CAD) in 4D breast magnetic resonance imaging (MRI) usually regard lesion detection, segmentation and characterization as separate tasks, and typically require users to manually select 2D MRI slices or regions of interest as the input. In this work, we present a breast MRI CAD system that can handle 4D multimodal breast MRI data, and integrate lesion detection, segmentation and characterization with no user intervention. The proposed CAD system consists of three major stages: region candidate generation, feature extraction and region candidate classification. Breast lesions are firstly extracted as region candidates using the novel 3D multiscale morphological sifting (MMS). The 3D MMS, which uses linear structuring elements to extract lesion-like patterns, can segment lesions from breast images accurately and efficiently. Analytical features are then extracted from all available 4D multimodal breast MRI sequences, including T1-, T2-weighted and DCE sequences, to represent the signal intensity, texture, morphological and enhancement kinetic characteristics of the region candidates. The region candidates are lastly classified as lesion or normal tissue by the random under-sampling boost (RUSboost), and as malignant or benign lesion by the random forest. Evaluated on a breast MRI dataset which contains a total of 117 cases with 141 biopsy-proven lesions (95 malignant and 46 benign lesions), the proposed system achieves a true positive rate (TPR) of 0.90 at 3.19 false positives per patient (FPP) for lesion detection and a TPR of 0.91 at a FPP of 2.95 for identifying malignant lesions without any user intervention. The average dice similarity index (DSI) is

0.72
±
0.15

for lesion segmentation. Compared with previously proposed lesion detection, detection-segmentation and detection-characterization systems evaluated on the same breast MRI dataset, the proposed CAD system achieves a favourable performance in breast lesion detection and characterization.
