Six Sigma is a well-known business strategy for continuous improvement that focuses on enhancing products, processes, and outcomes by minimizing variation in processes and avoiding product deficiencies. Six Sigma DMADV (Define-Measure-Analyze-Design-Verify) methodologies is an influential approach to designing products, processes, and services to fulfill the requirements and potential of the customer while reducing the cost of quality. DMADV uses influential and constructive statistical tools to forecast and enhance quality before prototypes are built.This paper presents the case study approach to implement a Six Sigma DMADV methodology in an auto part manufacturing company to reduce the weight of Variable Transmission Unit (VTU) Housing for H1 transmission and hydraulic common oil vehicle Models to gain a competitive benefit.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"58 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81111206","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}

Precautionary safety measures were established to contain and reduce the widespread of the virus. However, in most cases, the global pandemic countermeasures imposed restrictions on physical access to financial, health, educational, shopping, factories, public transportation, and office buildings. In addition, the process of facilitating access based on customary identity verification and temperature collection can be high risk and time-consuming, especially if performed in a close encounter. Today, many surveillance and security companies can provide a practical solution, though with a high cost. The merit of this practice is to utilize Artificial Intelligence to provide 1) remote image recognition accurately with face masks, 2) temperature recording and 3) low-cost solutions altogether. This study is developed in response to a Request for a Proposal by the UAE Ministry of Energy and Infrastructure. The study is directly related to developing low-cost system for people counting and temperature recordings using enhanced Viola-Jones algorithm with cascade objects for detection and tracking. Rudimentary analysis indicates 95% effectiveness of system, with more than 70% cost reduction, and opportunity for global implementation to ensure smoother transitions to new normal.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"12 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85440961","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}

Mourad, Saeed Al-Nuaimi","doi":"10.1109/ASET53988.2022.9734914","DOIUrl":"https://doi.org/10.1109/ASET53988.2022.9734914","url":null,"abstract":"Laminated composites with internal ply drop-off regions at specific locations, popularly known as tapered composite structures have found wide applicability, owing mainly to its weight savings and customizable mechanical properties. A detailed analysis is therefore vital to predict the mechanical response of these tapered laminates with plies terminating at specific locations. In the initial part of the study, a three-dimensional (3D) model of a flexbleam structure, which is a typical structural application of tapered composites is condensed to a two-dimensional (2D) model on certain assumptions. It is a symmetric ply-configuration structure exposed to a tensile load and analysis is carried out on a commercial finite element method (FEM) package, ANSYS 16.2. The study of induced interlaminar stress responses can aid in determining the factors influencing the strength and endurance of the laminate structure thereby, guide in the design of the ideal layout to maximize performance across various conditions and prevent delamination. The conventional 3D/2D analysis require high investment in terms of computational effort and time. Therefore, a mathematical asymptotic method, Variational Asymptotic Method (VAM) is introduced in second phase of this study in order to analyze the problem. It mainly involves decomposition of the 3D problem into a one-dimensional (1D) one, owing to the point that the thickness of rotating beams such as propellor, rotors, etc. is comparatively lower than the other two dimensions. The application of beam theory involves the introduction of variables depending only on beam axis co-ordinates. Unlike classical approaches, this is especially useful to capture non-linearities such as extension-twist coupling (trapeze effect). warping, etc. which may be dominating in thin-walled beam section found in rotor blades and turbomachinery. For this purpose, geometrically exact intrinsic beam theory derived using variational principle is adopted for the analysis. The solution obtained contains asymptotically exact static displacement and rotation variations of the structure for arbitrary loading and stacking sequence. Out of plane stresses (interlaminar) are recovered from global 3D equilibrium equations which can be further used for delamination studies.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"167 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85593900","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}

This paper aims to explore the potential for utilizing concrete blends of CEM I, blast furnace slag (GGBS) and cement kiln dust (CKD) at strategic proportions ranging from 40-75% for GGBS and 0-35% for CKSD, in order to determine optimally performing mixes at sustainable quantities. Fresh, mechanical and permeation properties of CEM I/GGBS/CKD concrete mixes were investigated and compared against a reference PC- based concrete. The results showed that moderate amounts of GGBS and CKD within concrete may not pose any risks related to the rheology of the concrete, and moreover, an optimum combination comprising of 55% GGBS and 20% CKD appears to offer promising performance aspects related to density, strength and absorption rates.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"90 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73302557","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}

However, the research on the material was hindered due to the instability of the zinc and copper in the quaternary phase, thus, resulting in secondary complex phase with defects. This led to the structural inhomogeneity, challenges in the repeatability of the synthesis procedure and degradation (especially) in the efficiency of the solar cell. Therefore, synthesis of CZTS in right phase and purity (without any stoichiometric imbalance as well as secondary phases and defects) is a challenge to overcome. Moreover, due to the presence of copper and zinc, it is an interesting material for the scientific community as gas sensor. In this report we have synthesized CZTS through chemical synthesis and examined a spin coated CZTS thin film for probable sensing application at room temperature. We utilized the CZTS thin-film for room temperature gas sensing of the volatile organic compound (ethanol) at 68 PPM. In addition, the Phase purity of the film was confirmed by the X-ray diffraction. While, the optical characterization of the film was investigated by the UV-Spectrometer.

It can be difficult to keep a cool indoor environment in a hot summer while still having a warm indoor environment during an extremely cold winter in warm summer humid continental areas. In this paper, an emphasis will be done on applying passive strategies in extreme climates; the focus will be kept on the buildings’ envelope. A sample case study of a Minneapolis educational building was chosen. Because the majority of Minneapolis' school buildings were constructed before the implementation of energy rules, the majority of them will require extensive renovations to meet the current legal requirements. This study used extensive virtual studies on an energy modeling tool to uncover passive design characteristics. The measures targeted were aimed at reducing huge heating and cooling loads in the winter and summer, respectively. To achieve the reduction in heating loads, a study was done on the indoor temperatures applying high thermal mass on the envelope construction elements. Cooling loads were reduced by focusing on the effect of natural ventilation strategies on indoor temperatures. The total effect of applying high thermal mass instead of the medium thermal mass within the building envelope can be seen in the 4-hour delay of peak temperatures inside the classroom. Moreover, to tackle the cooling loads, an emphasis was held on the use of natural ventilation strategies in summer. Applying high thermal mass and night flushing resulted in a 3 oC decrease in peak temperatures in summer. A CFD analysis was done to make sure that human comfort is maintained in terms of air velocities inside the classroom. Finally, it can be concluded that performing a thorough climatic and case study analysis to determine the best combination of passive techniques can significantly reduce energy use.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"36 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86643090","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}

These resources have intermittent nature which leads to a tradeoff between the inclusion of large shares of such sources of energy into the electricity network and their economical and environmental advantages. Therefore, it is important to study the impact of different meteorological variables on solar generation. To that end, correlation and interdependence among different meteorological variables were analyzed, and multiple linear regression was utilized to determine the significant variables that impact solar generation. Four years of hourly cumulative total solar generation of Spain has been used as a case study along with its meteorological variables. Twelve different multiple linear regression models were developed for each month and the significant variables were reported. The dependent variable was the cumulative solar generation in MW and the independent variables were the temperature, humidity, wind speed, pressure, and cloudiness. The variables with the highest influence were recorded for different months.","PeriodicalId":6832,"journal":{"name":"2022 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85168880","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}
