Specifically, the paper proposes solutions to solve these problems in the case of urban public transport by rail (tram). The results obtained by ISIM Timisoara (implemented at public transport companies in the country) in the field of reintroduction into operation of used metal components from trams are presented. It also presents new, innovative and efficient technical ideas and solutions, from the point of view of the cost / performance ratio and in compliance with the conditions for guaranteeing traffic safety. It is proposed to design and implement a flexible, complex and high-performance automated system for the reconditioning of tram wear components.The implementation of the proposed automated solutions will ensure: significantly increasing the service life of parts subject to wear, reducing the costs of loading with functional layers by increasing productivity, improving part quality due to automation of the loading process, use of constant process parameters, established, controllable during process. Innovative solutions are also proposed for: mobile automated inspection system for determining the degree of wear of tram wheel bandages; method of real-time monitoring of the welding loading process; technical solution to protect the rubber damping elements against overheating and degradation (the solution allows the tires to be reconditioned without removing them from the wheels).Accurate and efficient uses of automated systems, process programming units are specific approaches to the development and modernization of welding and reconditioning technologies by welding.","PeriodicalId":34329,"journal":{"name":"Journal of Electrical and Computer Engineering Innovations","volume":"53 1","pages":"31 - 39"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84459049","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}

Duma","doi":"10.4028/p-4isiu8","DOIUrl":"https://doi.org/10.4028/p-4isiu8","url":null,"abstract":"Paper presents the results of factorial experiments made to establish the influence of technological parameters of 3D printing using the Fused Deposition Modeling (FDM) Technology, on the mechanical properties of the material deposited with ULTRA PLA filaments. By planning the experiments and the statistical processing of the results, mathematical relations were established regarding the dependence between the objective functions, the controllable factors and their interactions. To obtain high tensile strengths of the components made by 3D printing, regimes are required to allow the deposition of layers as thin as possible (h = 0.1 mm) and temperatures as high as possible, close to 300°C. The choice of inappropriate values of these process parameters can lead to a significant decrease in tensile strength, reaching even up to 30-40% of the maximum possible value to be reached. The experiments reveal that the printing speed does not have a major influence on the mechanical properties. Practical, the printing speed is limited by the technical characteristics of the printer used. The results of the experimental research obtained on a number of 30 process variants led to the establishment of optimal 3D printing variants that correspond to the requirements imposed on the objectively analysed functions (tensile strength, dimensional accuracy, speed of execution, surface quality).","PeriodicalId":34329,"journal":{"name":"Journal of Electrical and Computer Engineering Innovations","volume":"49 1","pages":"7 - 20"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73647670","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 its size and design, CubeSat parts like casings can be produced and assembled through 3D printing to produce inexpensive satellites. Research in this area is undeniably important to maximize the rapid development of CubeSats. While progress has been made, challenges remain in applying 3D printing technology in the development of CubeSats. In this paper, the current status regarding the advancement of 3D printing for CubeSat applications is discussed. First, important issues about the common materials for CubeSat and potentially 3D printing materials for CubeSats are addressed. Second, 3D printing CubeSat parts through the feasible structure design models by combining material and parameter designs are explored from a wide range of references. And also, 3D printing of cube satellite parts by DOST AMCen and STAMINA4Space has also been demonstrated. Lastly, an outlook on the future direction of the 3D printed CubeSat for the Philippines space program is provided.Keywords: Cube satellite, CubeSat, 3D printing, high-performance polymers","PeriodicalId":34329,"journal":{"name":"Journal of Electrical and Computer Engineering Innovations","volume":"49 1","pages":"13 - 27"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88395480","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}

Ardufarmer is a seed sowing machine that combines the emerging additive manufacturing technology and quadcopter robotics to form an alternative broadcast farming method that efficiently covers a given land area in the least amount of time through planting toolsets: seed reservoir, dispenser valve, drill, Arduino, and GPS programming. The quadcopter development includes designing the drone fuselage and seed dispenser, three-dimensional printing (3D printing) the parts under different settings, simulation and analysis of 3D-printed parts, and programming the Arduino board and GPS mechanism. The drone was tested in different land areas in terms of time spent. The study shows that the planting rate of the drone is more efficient at 36.41 seconds in 50 square meters than manual planting at 144 seconds in 50 square meters. The Ardufarmer was tested in terms of height, time spent, and spreading diameter in different land areas. The device can effectively sow seeds in 12 seconds per square meter. The study also shows that the minimum percentage relative time saving of the proposed drone technology is 74.72%.","PeriodicalId":34329,"journal":{"name":"Journal of Electrical and Computer Engineering Innovations","volume":"14 1","pages":"39 - 51"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80103823","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}
