However, optimizing resource utilization and achieving a good surface finish remain challenging tasks. Excessive tool usage and poor surface finish are common problems encountered in turning centers, which affect productivity and product quality. In this research, we propose an approach that leverages automation and machine learning techniques to maximize tool use and improve surface finish. Our objective is to investigate the relationship between tool life and surface roughness and to develop a method that can optimize cutting parameters for turning centers. We have conducted an experimental study to evaluate the proposed approach, which involves the automatic determination of cutting parameters based on machine learning algorithms, and concluded a cutting speed of 43.10[Formula: see text]m/min, the surface finish achieved for aluminum material was 1.98[Formula: see text][Formula: see text]m. In the case of mild steel material, the surface finish was 12[Formula: see text][Formula: see text]m at a cutting speed of 25.13[Formula: see text]m/min. Similarly, for cast iron material, the surface finish was 8.45[Formula: see text][Formula: see text]m at a cutting speed of 30.16[Formula: see text]m/min. Our results show that the proposed method outperforms the traditional manual method in terms of surface finish, tool usage, and machining time. Our approach can be applied to other machining systems, providing a practical and effective solution to improve the efficiency and quality of machining processes. This paper presents an experiment that explores the relationship between tool life and surface roughness. Furthermore, an automated approach is proposed for eliminating G code in machining, which can improve the efficiency of machine tools and result in a better surface finish. Objective: To maximize tool use and improve surface finish in turning centers by incorporating automation and machine learning. Idea: This research aims to explore the use of automation and machine learning in turning centers to optimize the cutting parameters and achieve a better surface finish. Description of the idea: The study was conducted by performing experiments on three different materials, i.e., aluminum, mild steel, and cast iron. The cutting parameters, including spindle speed, feed, and depth of cut, were controlled by a programmable logic controller (PLC) integrated with a tachometer and Vernier scale. The surface finish was measured using a surface roughness tester, and the data was analyzed using a supervised machine learning algorithm.","PeriodicalId":29682,"journal":{"name":"Innovation and Emerging Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75638492","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 miniaturised microstrip antenna structure based on metamaterial (MTM) is presented here. The objective of this work is to present a high-directive antenna for wireless systems utilising MTM properties. Directivity is improved by the incorporation of the MTM structure on the ground structure. In order to improve the performance parameters of the antenna for medical applications, this study provides the design and analysis of a multiband patch antenna employing split-ring MTM. The split-ring resonator (SRR) MTM structures are embedded in a unique and novel way in the ground structure of the antenna.

The reference antenna is a rectangular microstrip patch antenna exhibiting a directivity of 1.1823[Formula: see text]dB that resonates at a frequency of 2.32[Formula: see text]GHz. The optimised SRR MTM is positioned in the ground plane of the suggested antenna to increase the directivity of the antenna.

Previously considered a fast prototyping method, it offers significant benefits for use as a method of producing user-end parts that are limited in quantity, customizable, and/or complicated geometries. For AM to be considered in high-performance applications, such as automotive and aerospace, we must consider AM technology and the available and compatible printing materials. Typically only thermoset plastic resins are capable of meeting high-performance specifications, such as sufficiently high strength, stiffness, and toughness, as well as excellent chemical and environmental resistance. This review presents a broad overview of the available high-performance thermoset chemistries and formulations, i.e., resin blends. The base resin chemistries that are covered are: vinyl, epoxy, imides, cyanate ester, urethanes, benzoxazine, and click chemistries (e.g., Michael addition). Subsequently, more application-relevant blends of these base resins are discussed. Each section focuses on resin details such as reaction mechanisms, typical monomer structure, mechanical properties, and applications specific to AM. The review is organized as follows. We begin with an introduction on the state-of-the-art, the challenges still faced by the field, and a benchmark definition of “high performance.” This is followed by a discussion of the available AM technologies for thermoset printing, with a focus on their advantages and disadvantages. Next, we cover the details of different resin chemistry, followed by their blends. The following section details the difficulties in developing AM technologies that allow for the incorporation of fillers, such as rheological modifiers and reinforcements. The review ends with a perspective on the future of AM technologies that would bridge the gap between pure resin printing and the much needed composite printing for high-performance applications.","PeriodicalId":29682,"journal":{"name":"Innovation and Emerging Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135610686","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}

Despite its rapid growth over the past decade, the acceptance of hybrid AM within the industry has been limited due to various constraints. To achieve industrial acceptance, it is necessary to address the challenges and limitations of AM. As an effort to mitigate environmental concerns, manufacturers have recently started to explore integrating additional and secondary production methods into their manufacturing processes. Integrated production solutions have shown promise in overcoming present-day barriers in production systems by utilizing the best available integration technology. In this context, this article focuses on three critical points in the manufacturing sector. First, recent developments in the integration of AM processes have been significant. Second, integrated technical planning has been improved, which is essential for the successful implementation of hybrid manufacturing. Finally, there is a growing need to understand the mixed supplement production industry that combines both traditional and AM techniques.

The findings of this article indicate that the dataset utilized proposed model provides an acceptable algorithm for FACC design and optimization. In the current study of preparation of geopolymer concrete (GPC), relevant variables such as curing, fly ash, calcined clay, added water, super plasticizer, coarse aggregate, quarry stone dust, caustic soda, and water glass were used as input parameters. The ranges, mode, median, standard deviation, and other identifying details were checked using descriptive statistical analysis for the input parameters. The strength due to the compression of FACC GPC was predicted using RFR, LR, and KNN ML techniques, all based on Python coding. The ensemble ML technique, RFR outperformed the individual ML technique, KNN, in terms of prediction. The RFR indicates that the maximum amount of [Formula: see text] is 0.92, and LR provides 0.58, although the KNN was less accurate, with a coefficient of determination of 0.56. The RFR technique’s lower values of errors, mean absolute error (MAE), MSE, and root mean square error (RMSE) yield 1.99, 7.17, and 2.67[Formula: see text]MPa, respectively. The excellent accuracy of the RFR methodology is confirmed by a statistical analysis of errors. Curing temperature, curing hours, molarity of NaOH, and FACC ratio significantly affect the compressive strength (CS) of FACC GPC.

The difficulty of obtaining an accurate clinical diagnosis from radiographs rises due to the minimal mineral density change in demineralized tissue of tooth and gum disorders. Dental abnormalities may not be visible on radiographs until the demineralization is higher than 40%, according to the literature. As a result, a dental practitioner’s judgment can have a big impact on how accurately the radiography penetration depth is determined through visual inspection. To counteract this effect, image processing-based clinical diagnosis methods have become widely adopted, transforming dentistry from traditional to advance in recent years. The efforts made in the area of image processing-based digital dental diagnosis of the most challenging dental issues are outlined in the presented comprehensive literature evaluation, which also identifies any research gaps in the scope of work already done. The included studies’ quality was evaluated using Quality Assessment and Diagnostic Accuracy Tool-2 (QUADAS-2). A total of 52 out of 178 articles, published from 2012 to February 2023, were reviewed and data like image-processing approach, the size of datasets, approach results, advantages and disadvantages, name(s) of diagnosed diseases, imaging type, author, and publication year were extracted. Results show that, in 52 studies, more than 14 image-processing approaches were used on different types of radiographs for the diagnosis of a single or more than one disease by a single approach with an accuracy range from 64% to 93%. Most studies have used artificial intelligence (AI) for computer-aided diagnosis and used dental experts to label their dataset and validate the outcome of proposed methods. Efforts done by different research groups for image processing-based digital diagnosis are appreciable but still, they are lagging to meet clinically expected accuracy. There looks to be a great requirement for the development or standardization of existing methodology and it is also needed to construct standard public dental datasets to attract a greater number of research groups in the dental field.","PeriodicalId":29682,"journal":{"name":"Innovation and Emerging Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83523939","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}

Current preclinical models of GBM fail to predict clinical outcomes, thus, new translationally relevant models are urgently needed for reliable therapeutic target validation. 3D spheroid culture of cancer cells has been shown to better reflect tumour biology than 2D monolayer culture, as has culturing cells in flow-based microfluidic devices, which mimic key aspects of the tumour microenvironment. Gene knockdown by siRNA is a key preclinical target validation tool, however, siRNA-mediated knockdown of cancer spheroids in microfluidic culture has not yet been demonstrated. Here we describe a simple and robust microfluidic device that can maintain GBM spheroids (U87 cells) for at least 7 days. Via RNA sequencing analysis, we demonstrate that spheroids grown in microfluidic culture are more proliferative than spheroids grown in static plate culture and downregulate genes associated with cell adhesion, potentially offering insights into the metastatic process. Comparison of target gene (PRMT2 and RAB21) knockdown using siRNA between 2D monolayer cultured cells, static spheroid culture and spheroids maintained in the microfluidic device showed that gene expression (as measured by quantitative-PCR) was significantly reduced in all culture systems. Knockdown was most efficient in cells grown in 2D monolayer culture followed by static spheroid culture, but we also demonstrate [Formula: see text] knockdown efficiency using the microfluidic device. In summary, this study describes an easy-to-use microfluidic culture platform and provides evidence that pre-clinical siRNA-mediated target validation studies will be possible in flow systems that mimic tumour physiology.","PeriodicalId":29682,"journal":{"name":"Innovation and Emerging Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135319309","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}
