Where, a program designed using MATLAB environment has been developed to transfer these geometrical data and a technique to transfer geometrical curves to full descriptive surfaces using the UGS software as a CAM tool without any loss in their geometrical shape information also has been demonstrated, therefore the matrix of nth degree of the Bezier curves and B-spline curves and surfaces generation had been examined to use it in this work as an analyzed case to examine the suggested method and program script. It has been noticed through the implementation of the developed script and the simulation phase using the UGS system that this script can be applied to transform any free form surface profile shape from CAD module to CAM module without missing any kind of geometrical information in the final geometry of the profile, subsequently G-code for any free form geometry can be obtained. The current technique aligns conformity with the experimental result.","PeriodicalId":237887,"journal":{"name":"2020 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123439327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we investigate on material selection for tactile sensors that mainly uses conductivity information to infer deformation. Hence, flexible and conductive materials are required to allow deformation over complex 3D surfaces and to allow the flow of electric current. Conductive fabrics have gained interest in research as membranes in tactile sensors. The main advantages of employing fabric materials are an improvement in signal hysteresis and an increase in detection sensitivity through employing multi-layered fabric structures. However, this adds on the cost of fabrication and the complexity of the design. In this contribution, a technical review is provided on various types of membranes in the context of large contact area tactile sensors. Moreover, two commercially available silver-plated knitted fabrics coated with silicone and the other with nitrile rubber are investigated as single layered membranes. The experimental results demonstrate that both the weft and warp directions of the fabric and material coating have a significant effect on the materials' mechanical and electrical performance. The elastic modulus of the nitrile rubber coated fabric is in the range of 0.14 MPa and 0.30 MPa, while that of the silicone-coated is in the range of 1.36 MPa and 1.87 MPa respectively for the weft and warp directions.","PeriodicalId":237887,"journal":{"name":"2020 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124091319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The essential primary duty of any DNO is to provide uninterrupted electricity supply to their customers. So, having a deep understanding of network faults has always been principal importance for reliable and sustainable power supply. The purpose of this study is to discover the relationship between population density and low voltage (LV) faults causes in an electricity distribution network using machine learning classification models. The study aims to use different classification models and comparing the results. The results of this study should outline the ideal classification model to use in understanding the relationship between population density and LV faults causes. In this study, the correlation method has been used for feature selection to select the most suitable variables to build the classification models. It should also give more insight into how the data should be prepared before being input into a machine learning classification models. Correlation analysis has revealed the multifaceted relationships that exist among the variables in multivariate fault data. From this study results and analysis, the shows that there is a new relationship between local population density and fault causes which suggest fault causes has a strong relationship with population density. These findings may help DNOs in policy-making and network design. Also, this research may assist Smart City planning projects.","PeriodicalId":237887,"journal":{"name":"2020 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126319473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The images analyzed were phantom based using standardized NEMA ICE body phantom that consist of six fillable variable spheres sizes. A NOVA t-test was used for statistical difference studies. Using bone and abdomen/ pelvis CT windows resulted in a sphere underestimation of up to 3 mm. While using T1 and T2 MRI windows yielded an underestimation of up to 3.5 mm especially in the small spheres. Significant spheres size differences were seen with PET windows shown an overestimation of up to 7 mm using CE equal and thermal windows. Improper selection of windowing while viewing 2D displayed images can yield considerable inconsistency leading to unreliable measurement.","PeriodicalId":237887,"journal":{"name":"2020 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122496898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim is to check if dimples will improve the efficiency of the structure by increasing lift to drag ratio and stall angle or decreasing drag force on the airfoil. The surface modification was done by considering the different arrangement and location of dimples at various Reynold numbers. Dimples help in reducing pressure drag when the airfoil is at larger angles of attack, as the angle of attack is increased, the wake formation starts to occur due to boundary layer separation. Dimple effects on the airfoil surface in same manner of what vortex generator does. Both methods aim to produce turbulent boundary layer in which wake area is reduced therefore reducing pressure drag. For the design process, ANSYS FLUENT was used to computationally investigate the effects of using dimples over the airfoil surface of NACA 2412. A comparative study was conducted between a normal airfoil (no dimples) and dimpled-surface airfoil, at different angles of attacks. It has been found that lift to drag ratio was increased by an improvement of 39.9%. It has been found that the flow separation on the NACA 2412 was delayed by the dimples effect. The critical angle of attack, which the stall occurs was also increased.","PeriodicalId":237887,"journal":{"name":"2020 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127684763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the intention to improve the strength, retaining the desirable properties of aluminium, particularly its lightness and corrosion resistance, many alloys have been developed. A390 is such an aluminum alloy, which is light weight and having good wear properties. A composite is a multiphase material and having better properties. A390 alloys and silicon carbide particulates were used to fabricate particulate reinforced aluminium metal matrix composites. Squeeze casting is a fabrication technique where solidification of liquid metal is promoted under applied hydrostatic pressure. In this work, A390- Silicon carbide composites of different weight fraction of silicon carbide were fabricated by squeeze casting and gravity casting through stir casting route. Squeeze castings were done at 50 MPa and 100 MPa squeeze pressures. Specimens of the composites were prepared and characterized through microstructural and wear analysis, tensile and hardness tests. The test results obtained for squeeze casting and gravity casting composites were compared and the effect of squeeze pressure was studied.","PeriodicalId":237887,"journal":{"name":"2020 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"53 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133437262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
