Published: March 2021

Abstract
One of the most desirable things for human beings is to own a house. Some governments, such as in the United Arab Emirates (UAE), have a system with different programs for their citizens to own the house. Generally and by applying one of the available programs, there are two ways to own a house in the UAE. The first way is to get a loan and buy a house that is already built (constructed house), and the second way is to get a loan and build a house on owned land (non-constructed house). The main purpose of this study is to define the citizens’ preferences between these two options, furthermore the issue based on these preferences and compare them with the non-citizens. Also, this study explores their perceptions of number of features that can be applied in their future house. The authors applied a Simi-structured interview targeting the current and potential house owners in Al-Ain city, UAE. The authors found that most of the participants prefer to build their own (non-constructed house) instead of buying a (constructed) one. Also, the most desirable features that the participants prefer are the ones they can benefit while occupying the house (i.e. flexibility to add or remove spaces, and flexibility to change the house elements).

Abstract
The present research goals to investigate how the preparation technique became the factor to develop materials with a good combination of properties and optimum degradation ability. PLA/CNTs nanocomposites were prepared via melt blending and solution blending that were involved of unmodified carbon nanotubes (CNTs) and modified CNTs (mCNTs) at 1.5 wt.% loading. The surface morphology of nanocomposites was viewed by Field Emission Scanning Electron Microscopy (FESEM). The effect of 5 wt.% poly (ethylene glycol) (PEG) as plasticizer on nanocomposites were determined. The weight loss in soil degradation study was run for 6 months. The morphology study by FESEM confirmed the finding through the existence of a smooth fracture surface especially when PEG was loaded. In soil degradation analysis, neat PLA exhibited a low weight loss rate after 6 months. The maximum weight loss for both techniques was shown by PLA/PEG/CNTs from melt blending technique and PLA/PEG/mCNTs from solution blending, believed from the pore occurred bring to poor properties.

Abstract
Nowadays, brazing has been widely used in many industries, especially in the automotive application. The brazing process is introduced as it can be used to join the different metals together without melting the parent material. In this present study, furnace brazing and laser brazing of Ti-6Al- 4V titanium alloy and 316 L stainless steel (SS) with silver-based, BAg 8-1.5Ti filler metal were studied. There are significantly different between furnace brazing, also known as conventional brazing method and laser brazing in terms of joining strength and microstructure reaction. Furnace brazing was performed at 870°C and 880°C with 30 minutes of heating duration. Meanwhile, laser brazing was performed using a 200Watt continuous wave laser with varying laser power. Both of brazing method was conducted with a vacuum pressure of 3×10−3 Pa. Besides, to maintain the accuracy of the temperature measurement of laser brazing, an infrared thermometer is used. The tensile test was conducted to analyse the mechanical properties. The cross-sections of the brazed joints have been examined using an optical microscope. The brazed joints of the furnace brazing show an average tensile strength of 55.89 kPa for 880°C and 43.16 kPa for 870°C. Nonetheless, the maximum tensile strength of laser brazed joints was 27.95 kPa, which is lower than furnace brazed joints.

Published: March 2021

Abstract
This paper reviews the progress on the corrosion characterization of magnesium (Mg)based material prepared by the powder metallurgy (PM) technique. In recent years, Mg alloys and composites produced by the powder metallurgy technique have been gaining interest in many industries especially in biomedical applications. Mg is also being used to improve battery electrodes and be considered for next-generation secondary batteries with remarkable energy and capacity density. Nevertheless, bare Mg is known to have poor corrosion resistance in most environments with occurrences such as non-uniform corrosion attack, high and fast reaction, microgalvanic corrosion of Mg-matrix and intermetallic particle and formation of non-protective hydroxide film after longer exposure in corrosive environment. New fabrication methods of Mg, such as the PM method are likely to benefit future Mg’s mechanical and corrosion properties. Utilizing the latest corrosion characterization method is needed to ensure accurate and precise methods for investigating corrosion behaviour. The recent approach and progress in characterizing Mg’s corrosion behaviour, specifically that have been prepared by the PM technique is considered in this paper.

Abstract
The present study evaluate the performance of SiO2 nano cutting fluid in CNC turning of AL319 Aluminium Alloy combined with MQL technique. The cutting performance namely surface roughness, cutting temperature and tool wear were investigated against feed rate and spindle speed. The spindle speed of 1000 to 1800 RPM and feed rate of 0.10 to 0.20 mm/rev were used as the input parameter. While the MQL nozzle pressure is kept constant at 0.5 MPa. The cutting performances of SiO2 nano cutting fluid with three volume concentrations (0.5, 1.0 and 1.5%) were then compared to the conventional CNC cutting fluid. Beforehand, the suspended form of SiO2 is dispersed in CNC conventional coolant base. One-step and dilutions methods were used in preparing nano cutting fluid. Response surface method (RSM) via Face centered design (FCD) was employed in designing the experimental work. The stability of SiO2 Nano cutting fluid is observed via visual sedimentation. The experimental outcome depicts lowest cutting temperature of 28.4°C and surface roughness of 1.08902 Ra when SiO2 nano cutting fluid with 1.5% volume concentration is employed. It can be concluded that the higher the SiO2 Nano fluid volume concentration, the better the surface roughness quality and lowering the cutting temperature. While no significant result shown in tool wear due to short period of experimental cutting time and relative soft material coupled with coated insert carbide used. Longer cutting time with higher concentration of SiO2 nano cutting fluid is recommended in future work in order to obtain significant result in tool wear.

Published: March 2021

Abstract
In this study, the effects of aircraft noise on the residents living nearby Sultan Ismail Petra Airport, Kelantan, Malaysia, were investigated. A questionnaire survey involving 60 participants revealed that 46.67% agreed that aircraft noise is a source of disturbance in their daily routine. On-site noise level measurements were carried out over a 2-week period at seven locations (P1–P7) surrounding the airport, where each location represents a different distance from the noise source. The daily average noise levels were within 50–65 dB(A), which exceeded the World Health Organization’s recommended maximum indoor noise level and recommended maximum outdoor noise level of 35 and 55 dB(A), respectively. However, the daily average noise levels were lower than permissible exposure limit of 90 dB(A). Based on the results, it can be concluded that exposure to the aircraft noise may affect the quality of life of nearby residents in the long term.

Authors: Sreenath S. , Sudhakar K. , Yusop AF 
Published: March 2021

Abstract
The application of solar PV is suitable in airport areas for energy generation due to the availability of vast open spaces. At the same time, there is possibility of glare from solar PV array which may affect the visibility of pilots and air traffic controllers. This paper attempts to perform glare assessment for conceptual solar PV system located in an airport of India using ForgeSolar software under four different scenarios. These four scenarios are solar PV modules with smooth glass, smooth glass with anti-reflective coating (ARC), light textured glass with ARC and different tilt & orientation angles respectively. The location of the proposed site, details of solar PV array and characteristics of observers are provided. The occurrence and duration of glare for each scenario is obtained from the software. The impact of glare is assessed based on solar glare standard set by Federal Aviation Administration (FAA). Among the studied scenarios, safe value of glare is obtained in Scenario 4 only at specific values of tilt and orientation angle. A tilt angle of 15 degrees and orientation angle of 135 degrees is the suitable value with 99.1 % of theoretical energy output. It is observed that the yellow glare impact on ATC reduced in the descending order of Scenario 1 (2122 min), Scenario 2 (296 min) and Scenario 3 (0 min). It is concluded that proper selection of tilt and orientation angle of solar PV array aids in achieving zero minutes of glare for airport conditions.

Abstract
The development of small-scale industry (SME) has increased the demand of small-scale CNC machines since the implementation of machine in production of small-scale product shown a profitable economic value. The use of machines in the fabrication of small part has been proven to increase product production efficiency as well as reduce product costs. This is able to increase the business profits of small companies and push the business development to a higher level. The main purpose of this paper is to discuss the development of 3-axis CNC machines using integration between microcontroller as main controller and spindle drill. The main application of this built machine is to cut and carve low-hard materials such as wood and acrylic material. The design product to be fabricate is sent to the microcontroller through a serial communication system. The microcontroller will control the movement of the spindle drill according to the point coordinates to perform the desired engraving or cutting according to the desired design. Three tests to determine the quality of product production are carry out. The tests are surface section, circular test and axial perpendicular test which can determine the accuracy of cutting geometry such as position, straight, roll, tone, evaporate and perpendicular to the work section under certain tool grooves and feed rate. The results of tests carried out on the products produced by the 3-axis CNC machine developed showed that this machine has a cutting and engraving accuracy of 98.5% and a depth accuracy of 100% for wood and archival materials. This machine is suitable for carving 2D and 3D objects with a maximum size of 30 cm x 30 cm.

Mathematical modeling of overhead crane under conditions of stress-strain state of metal structure as a control object
Authors: Lenivtsev A G , Dudanov I V , Fadeev A S 
Published: March 2021

Abstract
The article considers an example of the application of the existing mathematical model of an overhead crane to equipment with irreversible structural defects. The course of the solution of the problem is considered: obtaining primary data, finding the existing mathematical model of the crane, adapting it to the problem in question, building a computational model, modeling and analyzing the results obtained. The peculiarity of a crane as a control object is the non-typical state of the metal structure. The overhead crane is in this state after prolonged operation of the equipment with incorrect loading and control modes. As a result of such operating modes, significant wear of the wheels and the rail track take place. Worn elements must be replaced. The frequency of wheel replacement is very intensive, and is about twice a year. The process of replacing wheels with corner boxes is a very expensive procedure – it is necessary to buy equipment, stop the warehouse for a few days and attract staff. To eliminate such costs, it is proposed to conduct a simulation of the crane in order to identify methods of controlling it. The result of the first stage of modeling is the answer to the question: is it possible to operate the crane that is deformed using the correctly selected control mode.

Abstract
The studies assess the possibility of increasing the corrosion resistance, wear resistance of the surface of steel St3 using the method of plasma surface modification. The addition of OK 84.78 electrode coating powder in mixtures containing NiCrBSi leads to the increase of surface hardness. It is shown that the higher the content of OK 84.78 coating powder in the modifying mixture, the higher the probability of occurrence of defects in the fused surface layer (cracks, pores, heterogeneity). Studies of corrosion processes in a 3% NaCl solution show that coatings containing alloyed elements Cr, Ni have a higher passivation in a corrosive environment. NiCrBSi + 20% OK 84.78 coating is considered to be high corrosion-resistant.
Improvement of the technology for laying corrugated pipes for creating culverts under roads
Authors: Serebrennikov A A , Serebrennikov D A 
Published: March 2021

Abstract
The widespread use of polypropylene corrugated pipes for free-flow culverts requires that the construction technology ensure compliance with their physical and mechanical characteristics during their service. The use of polypropylene corrugated pipes for culverts in road construction poses greater demands on them. The paper considers the behavior of a buried pipe in interaction with the surrounding soil. The contradictions in the current building codes and regulations have been revealed. It has been proven that for polypropylene corrugated pipes, the resistance of the backfill soil, depending on the degree of compaction, is an essential factor in ensuring the long-term stability of the circular cross-section of the pipe. Theoretical calculations have confirmed that, depending on the backfill depth, the relative deformation of polypropylene corrugated pipes may exceed the maximum permissible values. An engineering solution has been proposed that provides an increase in the rigidity of the pipe bearing reaction under compressive forces and a decrease in the load from vehicles.

Authors: Korchagin A , Zaycev D 
Published: March 2021

Abstract
The purpose of the research is to assess the global quality of project design documentation for capital construction at the preliminary stage of investment projects in the context of the properties and qualities of applied construction materials. The problem of the assessment of the quality of construction and finishing materials in the subdivisions of Russian Railways, the largest Russian company, raises fundamental issues of regulatory and methodological support during the choice of engineering solutions and reasonability grounds of investments in the construction and reconstruction of transport infrastructure facilities. According to the formal indicators for the assessment of the properties of materials in the company, the authors used a method based on a separate analysis of the regulatory and methodological support of the construction preparation process. The main quality criterion was adopted in the form of deviations in documentation by the internal examination service of the company projects due to the unreliability in the determination of the physical properties of material resources. The main tool to influence the design process is the formalization of requirements for accounting construction materials, especially innovative ones, in project design documentation. These requirements are reflected in the proposed methodology for the generation of documentation at the early stages of investment project. A retrospective analysis of the verification results of infrastructure projects in the company showed that after the introduction of uniform requirements for the applied materials and the introduction of the basic provisions of materials science in the methodological documents, a positive trend has occurred during internal verification. The decrease in the number of incorrectly determined values of the need for construction materials indicate that cost certification has become more explicit and accessible to developers. It is proved that the tool for the management of the quality of construction materials by specifying the structure of documents justifying the main design decisions is the most effective. The idea is confirmed that the greatest responsibility for the efficiency of the applied material resources falls on the early stages of project development. The efforts made by the Company in this direction lead to positive changes.

Abstract
The paper considers the issues of improvement of the evaluation methods of new materials in construction. The features of regulatory control over the use of resources in Russia are characterized by the presence of a dual approach to choosing a regulatory framework, which in some cases leads to incorrect choice of materials. Engineering solutions during design are closely dependent on the cost parameters laid down in the regulatory and methodological framework. As a result, the problem of improving norms and methodologies is relevant for highly significant regulation. The property of recursivity of design solutions, normative support of construction and quantitative parameters of construction materials used in the design of structures is noted. The mutual influence of the process of developing standards and their further application in projects made it possible to use the recurrent formula tool for pre-design analysis of the possibility of using certain materials. The method allows performing a separate analysis of the possibility of application in projects for different materials, which can be useful when introducing new materials. On the basis of the proposed calculation method, conclusions on the need to improve the process of developing standards were drawn. The main problems of regulating the consumption of construction resources at the present stage are formulated. The need to design new standards based on the practice of applying new materials in construction projects was noted. The paper suggests the mechanisms to solve the problem of improving the reliability of determining a set of construction materials when designing construction works in transport construction, which would reduce the time for developing new and updating the existing standards. The assessment of the applicability of construction materials should not remain within the framework of subjective decisions of the engineering practice; on the contrary, it should improve the calculation methods to justify the applicability of materials.
