However, the data security was enforced at the attribute level, the adversaries are capable of learning the method of data encryption even there are access restrictions are enforced at an attribute level. To challenge the adversaries with more sophisticated security measures, an efficient real-time service-centric feature sensitivity analysis (RSFSA) model is proposed in this paper. The RSFSA model analyses the sensitivity of different features being accessed by any service and at multiple levels. At each level, the method checks the set of features being accessed and the number of features the user has access grant to compute the FLAG value for the user according to the profile given. Based on the value of FLAG, the user has been granted or denied service access. On the other side, the method maintains different encryption schemes and keys for each level of features. As the features are organized in multiple levels, the method maintains a set of schemes and keys for each level dedicative. Based on the service level and data, the method selects an encryption scheme and key to perform data encryption. According to that, the service access data has been encrypted at the attribute level with a specific scheme and key. Data encrypted has been uploaded to the blockchain and the method modifies the reference part of the chain to connect only the blocks to which the user has access. The chain given to the user would do not contain any reference from a specific block to which the user has no access. The proposed method improves the performance of data security and access restriction greatly.","PeriodicalId":10680,"journal":{"name":"Concurrent Engineering","volume":"41 1","pages":"249 - 257"},"PeriodicalIF":0.0,"publicationDate":"2021-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76626322","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}

Folestad","doi":"10.1177/1063293X211002169","DOIUrl":"https://doi.org/10.1177/1063293X211002169","url":null,"abstract":"Emerging research within the field of personalised medicines has aimed to enhance patient treatment through the use of pharmaceutical products that are customised to the individual needs and preferences of the patient. The currently dominant production platforms of pharmaceutical products, however, regard a mass production paradigm and are thus unfeasible for the production and provision of personalised medicines. The production platforms are not designed or are intended for a customisation context. Operating such a context with the current supply chain entails challenges such as increasing costs, time to patient and efforts in quality assurance activities. To address these challenges, this paper presents four reconfigured pharmaceutical supply chain designs. A qualitative operational performance assessment elicits the strengths and weaknesses of the respective supply chain design operating in a customisation context. The results suggest that a later point of variegation, that is, the point in the supply chain where the final customisation is achieved, can relieve the operational effort of the stakeholders in the supply chain while providing the benefits of personalised medicines, that is, an enhanced treatment outcome of the patient. A trade-off remains, however, between the supply chain’s decreased operational effort and degree of necessary reconfigurations, such as introducing new functions to stakeholder operation, reallocating activities to other stakeholders or educating stakeholders.","PeriodicalId":10680,"journal":{"name":"Concurrent Engineering","volume":"15 1","pages":"309 - 327"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89621469","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 accomplishments include prototyping a parallel three-axis robotic arm mechanism, assembling servomotors with associated encoders and gearsets, coding CANopen communication scripts for servomotor controllers and a host supervision GUI, coding forward/inverse kinematics scripts to compute the required servomotor rotations and the coordinates of a movable platform or the mechanism, coding tracking error compensation scripts for effective closed-loop griper control, and coding integration scripts to command and supervise the mechanism motion on the LabVIEW-based host GUI. During the development stage, this research designed and prototyped the parallel three-axis robotic arm mechanism based upon basic Delta robot kinematics. To control the mechanism effectively and accurately, this study implemented the CANopen communication protocol, which characterizes high speed and stable transmission. The protocol applies to the CANopen communication channels among the controllers and the host supervision GUI. On the LabVIEW development platform, the coded supervision GUI performs issuing/receiving messages to the CANopen-based controllers. The controllers excite the servomotors and actuate the parallel mechanism to track prescribed trajectories in a closed-loop control fashion. Meanwhile, an electromagnet attached to the movable platform of the robotic mechanism performs satisfactory picking/placing object actions.","PeriodicalId":10680,"journal":{"name":"Concurrent Engineering","volume":"65 1","pages":"197 - 207"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85669922","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}

Recently, a new type of social manufacturing pattern emerges and shows potential for core factories to improve their limited manufacturing capabilities by utilizing the resources from outside socialized manufacturing resource communities. However, the core factories need to analyze the resource characteristics of the socialized resource communities before making operation plans, and this is challenging due to the unaffiliated and self-driven characteristics of the resource providers in socialized resource communities. In this paper, a deep learning and complex network based approach is established to address this challenge by using socialized designer community for demonstration. Firstly, convolutional neural network models are trained to identify the design resource characteristics of each socialized designer in designer community according to the interaction texts posted by the socialized designer on internet platforms. During the process, an iterative dataset labelling method is established to reduce the time cost for training set labelling. Secondly, complex networks are used to model the design resource characteristics of the community according to the resource characteristics of all the socialized designers in the community. Two real communities from RepRap 3D printer project are used as case study.","PeriodicalId":10680,"journal":{"name":"Concurrent Engineering","volume":"101 1","pages":"236 - 248"},"PeriodicalIF":0.0,"publicationDate":"2021-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90360179","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 total volume of datasets extracted for the process were 1580 in number under four categories of 50, 100, 150 and 200 sequences. The breast cancer prediction process was carried out in three major steps such as feature extraction, machine learning classification and performance evaluation. The features were extracted with sequences as input. Ten features of DNA sequences such as ORF (Open Reading Frame) count, individual nucleobase average count of A, T, C, G, AT and GC-content, AT/GC composition, G-quadruplex occurrence, MR (Mutation Rate) were extracted from three types of sequences for the classification process. The sequence type was also included as a target variable to the feature set with values 0, 1 and 2 for classes 1, 2 and 3 respectively.

In the optimization strategy, the research first defines a length-varying hyperparameter list for the deep-learning network, and the entities in the list adjust themselves to optimize the model scales. During the optimization process, this paper adopts a two-stage training scheme that gradually augments image datasets to improve HMI control-panel recognition performances, such as recognition accuracy and recognition speed to identify the CNC machine working status. Using an open-source PyTorch platform, this research establishes a cloud-based distributed architecture to build training codes for the deep-learning network, in which an applicable optimization model is deployed to recognize the CNC control-panel working status. The optimization strategy employs minimal codes to rebuild the architecture and the least efforts to reform the manufacturing system. The optimally trained model provides up to a 99.34% CNC panel-message recognition accuracy and a high-speed recognition of 100 images in 0.6 s. Moreover, the developed optimization strategy enables the prediction of necessitated dataset augmentation to training a practically implemented CNN network.","PeriodicalId":10680,"journal":{"name":"Concurrent Engineering","volume":"6 1","pages":"35 - 48"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79123734","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}

Smart sensors and actuators are integrated into industrial machines to enhance industrial activities and business-related applications with little to no human input. The analysis of the real-time data that is obtained from this vast internetwork of machinery allows for greater streamlining in the industrial processes and thereby provides an even greater benefit to businesses which adopt the IIoT framework. This special edition focuses on analyzing the interdependence and unavoidable overlap of big data analytics and IIoT. Businesses and industrial pursuits are often shaped by dynamic demands, changing environments, and even socio-political flux. In the rapidly evolving world of today, these catalysts of change may make it difficult for businesses to keep pace. As a solution to this problem, IIoT effectively facilitates intelligent industrial and customer-level operations by using advanced data analytics to positively transform business outcomes. With the accelerated advancements in IIoT, we can soon expect billions of interconnected machines to stream unprecedented volumes of sensor data at remarkable speeds. According to a report by the International Data Corporation (IDC), the big data and analytics market, which reached $60 billion worldwide in 2018, is expected to grow at a 5-year compound annual growth rate of 12.5%. An incline of this magnitude can be attributed at large to the growing importance of automation in industrial enterprises. This explosive growth in the number devices in IIoT networks and the consequential rise in the amount of data produced and consumed is an apt reflection of how the growth of big data and IIoT are mutually beneficial to one another. Businesses are benefitted by IIoT in terms of increased revenue, reduced costs, and increased efficiency. However, merely generating a large amount of data is not the end goal. The data streamed from IIoT sensors only become useful if the data is appropriately analyzed. Considering the sheer volume of the influx of data, storing, processing, and analyzing this data is prone to become problematic due to limitations in computational power, inadequate networking capacities, and insufficient storage. Security concerns also pose a large threat to the convergence of IIoT and data analytics. Securely handling data, maintaining it, and extracting the necessary insights from it require a robust security framework to prevent mismanagement and fraudulent use. Implementing such a framework successfully has been a challenge as data analytics in the IIoT context is still at its infancy. IIoT has taken a stronghold in the industrial paradigm with the intention to simplify, streamline, and automate industrial activities to achieve maximum output.
