Authors: Amer Yousef , singh Simranjeet , Doan Linh Thi Truc 
Published: January 2020

Abstract
One of the biggest concerns for every country is to look after their ageing population and provides them a safe life with safe medical equipment and technology. It is estimated that there will increase the ageing of the population in Japan, Western Europe, USA and India with 40%, 30%, 20% and 15%, respectively by the end of the year 2050. Hence, it will create a burden on aged care centres to hire more nursing staff members, which leads to increase the medication cost. One of the feasible solutions to solve this issue is to design the soft robots which will give care to patients at aged care centres. These robots can support patients by providing medicine to them without the assistance of the nursing staff during injury or illness. Therefore, this paper aims to investigate the need of the partial soft robotic arm which can look after patients like robots for interactive body assistance.

Published: January 2020

Abstract
This report presents experimental studies of electrical changes in photovoltaic sensitive elements based on a Por-Si: c-Si heterojunction during the adsorption of acetone molecules in a mixture of pure nitrogen. The porous silicon layer was formed by electrochemical etching on a p-type silicon wafer. The obtained samples were subjected to additional plasma-chemical treatment using hydrogen and fluoride ions after fabrication. Such surface treatment has a stabilizing effect on the electrical properties of the material and increases their adsorption sensitivity to polar molecules. The developed technology allows you to automatically change the sensitivity of photovoltaic sensors during the experiment, depending on the concentration of acetone. These photovoltaic sensors are able to expand the range of measured concentrations from 1 ppm to 10 vol%.

Published: January 2020

Abstract
With the increasing number of vehicles worldwide and the increasing demand for parking spaces, effective management methods are in urgent need to improve the utilization efficiency of parking spaces. In spite of many previous studies focusing on how to detect the status of parking spaces and guide vehicles, the schemes proposed by these studies can only provide certain parking information rather than effectively manage parking spaces. In this paper, a system based on intelligent parking lock is designed to realize functions of query, reservation and management, based on which, drivers can reserve the free parking space in advance. This system can ensure that the reserved parking space is not misoccupied, which can also automatically close the parking lock and perform functions such as billing after the vehicle leaves.

Published: January 2020

Abstract
This paper covers the application of the cross-correlation method for measuring the velocity of solid particles. Capacitive electrodes are used as primary sensors to measure the time required by the solid particles to cover a known distance between the electrodes. The capacitive variations of both the electrode sensors are stored in computer synchronously for offline estimation of the velocity of the solid particles. Single glass marble is used as a solid particle to conduct the performance in the lab for its good signal to noise ratio (SNR) and vivid graphs. Matlab R2018a is used as a programming tool to perform the cross-correlation algorithm. The distance between the sensors is adjusted optimally. The results were realistic to ensure the correctness of the system.

Published: January 2020

Abstract
Recently, vehicle parts such as center pillars and impact beams used in automobiles have been requiring materials that satisfy both high strength and impact absorption. Therefore, in this study, the applicability of the forming process of CR340 (cold rolled steel sheet)/CFRP Hybrid Composites which are a bonded material of cold rolled steel sheet having excellent formability and carbon fiber prepreg having high strength and high collision absorption in the vehicle parts was investigated. Hybrid composites are fabricated by stacking carbon fiber reinforced plastic (CFRP) prepreg on a cold rolled steel sheet (CR340) with Zn coating. Bonding materials were used at the interface between the CFRP prepreg and steel sheet. In addition, in the case of CR340/CFRP Hybrid composites which are made by bonding CFRP prepreg to the surface of press-formed CR340 material, it is impossible to manufacture complicated shapes due to an interfacial bonding separation phenomenon between the reinforcement and steel sheet. An adhesive agent developed by this research team was applied on the cold rolled sheet between CFRP and CR340 materials to enable the blank production of CR340/CFRP Hybrid composites. The heating time and temperature required for bending test were set similar to the curing curve of the CFRP prepreg. The surface roughness of steel materials is important in terms of their tensile strength and bending strength In this study, the steel sheet used was cold rolled 340 with Zn coating without surface roughness treatment for application to mass production in industry. This study investigates the properties of a CFRP/metal hybrid composite material. The hybrid was fabricated after spreading a developed binder on high-strength steel sheets (CR980) prepared by cold rolling and pressing. During the preparation of the CR980/CFRP hybrid composite, and its mechanical characteristics were investigated through bending, tensile, and lap shear adhesion test experiments.

Published: January 2020

Abstract
The theoretical investigation of wakefield acceleration of electrons by CO2-laser pulse with central wavelength of 10.6 μm and input peak intensity of ∼1017 W/cm2 in transient hydrogen-plasma waveguide has been conducted. The plasma waveguide is produced by the fast Z-pinch discharge inside a 3 mm inner diameter and 50 mm long capillary. The waveguide properties of the capillary Z-pinch plasma were obtained from the space and frequency dependent wave equation that combines the attenuated charged particle inertia and the light wave effects in the plasma for the ideal Gaussian laser beam. For simulation of temporal and spatial evolution of electron density and other plasma variables during the capillary discharge, we used a standard one-fluid, two-temperature one-dimensional magnetohydrodynamic (MHD) model complemented with atomic data of hydrogen. Simulations showed that the guiding channel occurs far from capillary wall and exists for a few nanoseconds. In terms of laser driven plasma wakefield accelerators (LWFA), the Z-pinch waveguide is able to extend the acceleration length over the whole capillary, assuming that a single-mode transmission takes place. To quantify such ability of the channel, a correlation coefficient was introduced and computed at different input beam spot sizes. An optimal beam spot size was determined by taking maximum of time average of the coefficient over the channel lifetime. At the end of the guiding channel existence, the repetitive focusing and defocusing patterns were observed with intensity increase at the focal points. For simulation of the wakefield acceleration of electrons in the different waveguiding regimes we used the particle-in-cell (PIC) combined with the aforementioned MHD model. Influence of the waveguiding regimes on the electron acceleration was demonstrated.

Authors: Stekolschik Alexander 
Published: January 2020

Abstract
Complexity in the product and production process in mechanical and aerospace engineering leads to the existence of a variety of structures like engineering and manufacturing bills of materials. The manual or partly automated creation of these structures leads to redundant data and quality issues. This paper describes the approach of an integrated structure management based on a reference structure. The development of an integrated reference structure management approach aims to enhance the quality of a product in combination with concurrent complexity reduction. The reference structure is customer- or order-neutral; it is utilized as a basis for other structures. This paper presents a software system-neutral approach for the customer-related configuration of this structure resulting in e- and mBOM. The implementation of the method framework (selection of use cases) in a standard product lifecycle management (PLM) system is part of the research.

Published: January 2020

Abstract
In order to effectively interfere with radar in the complex electronic countermeasure environment, this paper studies the cross-polarization interference method to the polarized integration mono-pulse array radar based on the radar antenna’s intrinsic property that it can receive the cross-polarization components. Firstly, the polarized integration mono-pulse angle measurement method of array radar is described. Then, the cross-polarization interference method for the polarized integration mono-pulse array radar is theoretically analysed, and it is proved mathematically that this interference method can bring the error term, leading to a decrease in measurement accuracy. Finally, a variant function of the singular function’s derivative is proposed to simulate the cross-polarization pattern of the sub-array. On this basis, the cross-polarization interference on the polarized array radar angle measurement performance is simulated, and the performance curve is obtained. The simulation results show that the cross-polarization interference can lead to a decrease in the angle measurement performance, and when the cross-polarization interference component is close to the echo co-polarization component, the interference effect is good. The power requirement for implementing the interference is low, so it is conveniently implemented in various confrontational situations. This provides an effective and easy-to-use smart radar polarization interference method for electronic countermeasures.

Published: January 2020

Abstract
The speed change of the press slider in the tensile region should be slower and the full load operation time should be longer to adapt to the stretching process. By analyzing structure and motion characteristics of the existing mechanical press, changing the main drive gear of the press, a new press with a slide part added near the bottom dead centre (BDC) with low speed characteristic was designed, which is very suitable for advanced manufacturing. According to the working principle and main features of the new combined press, the parametric design of the mechanical model was established by using ADAMS simulation analysis software. Through the parametric design of the pendulum length, several groups of sliding motion curves were obtained, and the influence of the rod length on the motion characteristics of the slider was compared and analyzed.

Published: January 2020

Abstract
This paper extends the theory of constraint solving and presents a method to solve logical expression constraint problems existing in the process of generating test cases automatically. It defines the concept of the logical expression constraint on the path of C programs. In order to improve solving efficiency, it also presents an algorithm of pre-processing and heuristic backtracking. Our experiment results show that the method can narrow the domain of variables from meaningless infinite intervals to a finite range and achieve better coverage, and the results also show that the algorithm can improve the testing efficiency and halve the time of generating test cases.

Authors: Khatha W , Ekarong S , Somkiat M , Jiraphon S 
Published: January 2020

AbstractIncrease in energy demand, stringent emission norms and depletion of oil resources have led the researchers to find alternative fuels for internal combustion engines. Pyrolysis oil extracted from waste plastics, by pyrolysis, as a fuel for internal combustion engines has been demonstrated to be one of the best available waste management methods. This research aimed to study and compare fuel properties, engine performance and emission of alternative fuel from pyrolysis of waste plastics, which focused on physical and chemical properties of waste plastic crude oil (WPCO) and waste plastic oil (WPO) obtained by fractional distillation process. The result shows that the physical and chemical properties of WPCO are quite diffrent from commerical diesel while the fuel properties of WPO were found to be similar to that of diesel. The experimental results showed that the use of WPO led to an increase in brake specific fuel consumption but the slightly reduction in the brake thermal efficiency was founded with respect to diesel fuel. The combustion of WPO tended to increase NOX while a reduction in smoke was obtained compared with the pure diesel fuel.

Published: January 2020

Abstract
A wearable upper limb exoskeleton for factory assembly positions was designed. The trajectory and dynamics of the worker’s arm during assembly was analysed. According to the power demand, the corresponding torque drive was designed at the shoulder joint. Then the corresponding scheme was designed. The effect on joint drive force was simulated on Adams. As shown by the result, pre-compression force and spring stiffness have a great influence on the driving effect. Finally, with the work of additional required force moment for the shoulder joint as the objective function, the two parameters of spring stiffness and pre-compression force were optimized. Compared to not wearing the exoskeleton, the energy consumption of the exoskeleton was reduced by 90%.

Numerical Investigation of Rough Micro- and Mini-channel Heat Sinks for Varying Aspect ratio
Authors: Qasim Ansari Munib , Zhou Guobing 
Published: January 2020

Abstract
Numerical simulations are performed to study the impact of aspect ratio on the micro- and mini-channel heat sink behaviours in the presence of sinusoidal surface roughness. A CFD model is first validated with the relevant reference data for laminar flow conditions using ANSYS-Fluent analysis. The found results of this validation study show that the simulation results agree well with the reference data. The considered channel height, absolute roughness height and diameter are 250 µm, 30 µm and 366 to 374 µm, respectively. The top and bottom rough walls are under constant heat flux conditions, while other walls are adiabatic with air as the working fluid. The micro- and mini-channels with long wetted perimeter and lower aspect ratio have shown more convective heat transfer but with slightly higher frictional resistance. The convective heat transfer and thermal performance factor both improve with the increase in Reynolds number where all the values are higher than 1. The maximum value of the thermal performance factor is noted up to 1.6 for the channel having aspect ratio of 0.038 (Reynolds number = 250). This study shows that micro- and mini-channel heat sinks are sensitive to surface roughness, Reynolds number where varying aspect ratio have influence on both flow and heat transfer performances in laminar regime.
