Fused deposition modelling (FDM) is among the widely used additive manufacturing technology to fabricate quality products with effective expenses. This investigation considered significant methodological parameters: layer layouts/ patterns (triangular and rectilinear), wall thickness (1.2,3.6,6) and infilled density (70, 85 and 100%) analyzed to check out right into their results on compression and impact mechanical behaviors of 3D-printed Poly Lactic Acid pulse (PLA+), utilizing FDM 3D printing machine. The Central Composite Face-centered (CCF)technique was conducted to design an optimal number of experiments. The compression and impact tests were applied according to ASTM guidelines. The results showed that the Rectilinear samples were mechanically weaker than the Triangle samples, as the samples with 1.2 mm outer wall and 70% or 85% infill collapsed abruptly. The outer wall thickness was the most effective parameter for all samples, as the triangle sample with 6 mm walls and 85% infill had the","PeriodicalId":159365,"journal":{"name":"Engineering Research Journal (Shoubra)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139325615","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 systematic review aims to explore the most popular topics within LSS in manufacturing over the past ten years (2014 to 2023), and to identify and analyze any gaps. Results found that LSS helps in improving quality, increasing sigma level, reducing non-added value, increasing productivity, reducing production costs, and improving customer satisfaction. Furthermore, the results can be used for a systematic literature review by researchers and manufacturing leaders before embarking on a journey of continuous improvement. Finally, this study proposed a LSS framework for the manufacturing domain, which includes 40 steps. Various tools like process mapping, KPIs, OEE, sigma level, seven quality control tools, process time analysis, value stream mapping, kaizen, 5S, brainstorming, and standard work have been used at different phases of DMAIC.","PeriodicalId":159365,"journal":{"name":"Engineering Research Journal (Shoubra)","volume":"323 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139326930","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}

Bioclimatic design is one such approach that aims to create comfortable and energy-efficient buildings by utilizing natural resources and local climate data. This paper delves into the concept of bioclimatic design in detail highlighting different bioclimatic strategies for residential buildings that help in achieving bioclimatic design goals. The aim of this paper is to provide a systematic review that explores and categorizes the bioclimatic architecture approaches, analysis and assessment methods, and strategies in a clear and concise manner. The methodology employed in this study is a literature review of bioclimatic architectural designs in residential buildings to comprehend their design approaches, analysis and assessment methods, and strategies. This study focuses on bioclimatic design, thermal comfort, and energy efficiency. Future studies on bioclimatic building design should focus on analyzing current strategies in different climate zones, testing new technologies and materials, exploring more strategies suitable for the local climate, and evaluating the integration of bioclimatic design with other sustainable approaches to create efficient and cost-effective buildings.","PeriodicalId":159365,"journal":{"name":"Engineering Research Journal (Shoubra)","volume":"145 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139331535","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}

A PV/Thermal system is used as a result to raise the output power of the PV modules by decreasing their temperatures. This work includes numerical and experimental outputs, a comparison between the electro-thermal behaviours of water and different percentages of AL 2 O 3 Nano-water (0.001 & 0.01) pass through a new back pipe structure (pancake) installed under the PV module is presented. Comsol Multiphysics and MATLAB simulators are utilized to apply the model. The experimental work runs for both Nanoparticle concentrations compared with water. The pumping power consumption is approximately 1% from the average output power of the system. The thermal results for 0.01 %wt of AL2O3 Nano-water show that the PV module temperature decreased about 14.04 % and 8.8 % compared with water and 0.001 %wt Alumina, respectively. In addition, the difference in water temperature is increased by about 21.6 % and 6.7 % for two different concentrations compared with water. That leads to enhancement in the module’s daily output power up to 14.6 % by using 0.01 wt% AL2O3 Nano fluid compared with cooling water.","PeriodicalId":159365,"journal":{"name":"Engineering Research Journal (Shoubra)","volume":"255 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139331460","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}
