The novelty of this paper is a new methodology of assessing blockchains using the Unified Theory of Acceptance and Use of Technology (UTAUT) (Venkatesh et al., 2003) alongside the distinguishing characteristics of blockchain implementations: trust, utility, and support. The paper distinctly aggregates existing approaches to present a concise assessment model. The distinguishing characteristics of trust, utility, and support in the context of UTAUT are beneficial for comparing and evaluating the myriad of blockchain implementations. The research encourages the examination of existing and future solutions using the UTAUT-focused attributes. The study has broader implications for blockchain solutions by providing contextual constructs necessary for acceptance and use.","PeriodicalId":412735,"journal":{"name":"International Journal of Strategic Engineering","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126285445","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}

Using proper channel coding can enhance the data transmission over PLC systems. The purpose of using channel coding is to encode the information transmitted over communication channel in such a way that in presence of other interferences and noise, the error can be detected and possibly corrected. This paper investigates the Bit Error Rate (BER) performance of PLC systems based on Orthogonal Frequency Division Multiplexing (OFDM), in presence of Middleton class A noise, and applying Trellis Coded Modulation (TCM) / Rectangular Quadrature Amplitude Modulation (QAM) TCM as a channel coding. Simulations are undertaken in Matlab 2013b. The obtained results illustrates that although trellis codes produce improvements in the SNR in presence of Additive white Gaussian noise (AWGN), they do not perform well with multipath power line channel and Middleton class A noise. Therefore the Rectangular QAM TCM has been used to enhance the results.","PeriodicalId":412735,"journal":{"name":"International Journal of Strategic Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129744234","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 method consists of inserting the record to record travel algorithm (RRT) in the artificial bee colony (ABC) in order to ensure balance between the diversification and the intensification phases. The new technique is named RRT-ABC, and it starts by launching the standard ABC, and then the onlooker research phase is enriched by the RRT algorithm. So, the main idea of this research work is to solve the NP-hard problem of minimizing the batch dispersion using a novel metaheuristic because of the limitation of exact methods. Experimental results, carried on sausage manufacturing in a French food industry, proved the highly efficient performance of the proposed RRT-ABC metaheuristic.","PeriodicalId":412735,"journal":{"name":"International Journal of Strategic Engineering","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128080584","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}

In doing so, the Sydney Metro ITS will be used as the basis for the case study. This paper also investigates the different perceptions for diverse rail transportation projects. Ordinarily, cities are composed of complex configurations which are supported by various disparate transport systems. These transport infrastructure in turn require comprehensive system thinking as the base research methodologies. ITS provides an excellent mechanism to simplify a city's complex transport configurations. Nevertheless, the core ITS components require careful integration and detailed attention to detail in their design. The ITS integration strategy would also amalgamate crucial transportation issues, including optimized system performance through increased productivity, improved road and traffic safety, and so on. Accordingly, this integration and consolidation of ITS would result in superior overall transportation planning schemes. The resulting improved planning methods will ultimately facilitate the various transportation operators to become better acquainted with the ITS, and to support the making of safer and more synchronized ITS. A synchronized ITS requires a comprehensive process to successfully integrate its components. To assess the Sydney Metro's ITS integration, this research utilized confirmatory factor analysis as the statistical method to produce a model indicating the existence of four sub-systems and emphasized safety standard as the key attribute for a successful deployment. The very high safety benchmark is the pinnacle of the Sydney's advanced rail transportation system.","PeriodicalId":412735,"journal":{"name":"International Journal of Strategic Engineering","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121401173","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 literature review approach was used to identify this economic decision-making implications on the project's outcomes. Studies show how projects' future is associated with decision making.

Further, to maintain its position as one of the most livable cities in the world, Melbourne needs to always look at ways to optimize technology and lifestyle while being conscious of its effects on the environment in order to encourage a sustainable development agenda. Such a stance is part of Melbourne's future sustainable urban development strategy including ‘Melbourne 2017-2050.' As a part of such strategy, this article discusses the possibility of underground urban structures (UUS) to further alleviate Melbourne's continuous urban development problems. Four case studies, Lujiazui, Hongqiao, Montreal, and Helsinki, were studied. These four case studies have some comparability with Melbourne's CBD. Particularly, both Montreal and Helsinki have relevance to Melbourne which is appealing. Predominantly, these two cities' main objective of UUS matches that of Melbourne's long-term urban planning goals. Noticeably, improving the livability along with reducing building operational costs are central to Melbourne's 2017-2050 planning and beyond. According to Melbourne 2017-2050, as a sustainable urban development focus, the city's high livability needs to be maintained together with finding alternative ways to reducing building operational costs. This research would thus serve as a springboard to further investigate the UUS for Melbourne city.","PeriodicalId":412735,"journal":{"name":"International Journal of Strategic Engineering","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133215875","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}
