Grid-based approaches render an efficient framework for data clustering in the presence of incomplete, inexplicit, and uncertain data. This paper proposes an entropy-based grid approach (EGO) for outlier detection in clustered data. The given hard clusters obtained from a hard clustering algorithm, EGO uses entropy on the dataset as a whole or on an individual cluster to detect outliers. EGO works in two steps: explicit outlier detection and implicit outlier detection. Explicit outlier detection is concerned with those data points that are isolated in the grid cells. They are either far from the dense region or maybe a nearby isolated data point and therefore declared as an explicit outlier. Implicit outlier detection is associated with the detection of outliers that are perplexedly deviated from the normal pattern. The determination of such outliers is achieved using entropy change of the dataset or a specific cluster for each deviation. The elbow based on the trade-off between entropy and object geometries optimizes the outlier detection process. Experimental results on CHAMELEON datasets and other similar datasets suggested that the proposed approach(es) detect the outliers more precisely and extend the capability of outliers detection to an additional 4.5% to 8.6%. Moreover, the resultant clusters became more precise and compact when the entropy-based gridding approach is applied on top of hard clustering algorithms. The performance of the proposed algorithms is compared with well-known outlier detection algorithms, including DBSCAN, HDBSCAN, RE3WC, LOF, LoOP, ABOD, CBLOF and HBOS. Finally, a case study for detecting outliers in environmental data has been carried out using the proposed approach and results are generated on our synthetically prepared datasets. The performance shows that the proposed approach may be an industrial-oriented solution to outlier detection in environmental monitoring data.

There are several environmental and human health impacts if human hair waste is not adequately disposed of. In this study, pyrolysis of discarded human hair was carried out. This research focused on the pyrolysis of discarded human hair under controlled environmental conditions. The effects of the mass of discarded human hair and temperature on bio-oil yield were studied. The proximate and ultimate analyses and calorific values of disposed of human hair, bio-oil, and biochar were determined. Further, chemical compounds of bio-oil were analyzed using a gas chromatograph and a mass spectrometer. Finally, the kinetic modeling and behavior of the pyrolysis process were characterized through FT-IR spectroscopy and thermal analysis. Based on the optimized mass of disposed of human hair, 250 g had a better bio-oil yield of 97% in the temperature range of 210–300 °C. The different parameters of bio-oil were: pH (2.87), specific gravity (1.17), moisture content (19%), heating value (19.34 MJ/kg), and viscosity (50 CP). C (56.4%), H (6.1%), N (0.16%), S (0.01%), O (38.4%), and Ash (0.1%) were discovered to be the elemental chemical composition of bio-oil (on a dry basis). During breakdown, the release of different compounds like hydrocarbons, aldehydes, ketones, acids, and alcohols takes place. According to the GC–MS results, several amino acids were discovered in the bio-oil, 12 abundant in the discarded human hair. The FTIR and thermal analysis found different concluding temperatures and wave numbers for functional groups. Two main stages are partially separated at about 305 °C, with maximum degradation rates at about 293 oC and 400–4140 °C, respectively. The mass loss was 30% at 293 ⁰C and 82% at temperatures above 293 ⁰C. When the temperature reached 410⁰C, the entire bio-oil from discarded human hair was distilled or thermally decomposed.

A fundamental issue for industrialisation and governments is the need to support innovation and change amongst industry individuals with a specific end goal to build efficiency and upgrade the business’ competitive position.

The Namibian energy sector and other energy sectors across the globe are currently in a rapid transformation era that must respond to climate change, which directly affects energy infrastructure’s resilience to the effects of resource scarcities or extreme weather conditions. The energy sector must implement adaptation to guarantee the resilience of vital infrastructure to fulfil its regulatory commitments, which cover the elements of resilience and safety. Through investigating climate change adaptation and mitigation implementation in Namibia, this study validates the existence of these co-benefits where integration is fully observed. It employed a meta-analysis and content analysis to link the observed variables to the most recognised co-benefits. The findings suggest that integration is an efficient way to generate co-benefits that contribute positively to the climate change project. Effective leadership support is one way of realising such integration, either via public-private partnership or energy policy. Namibian energy policy, it is suggested, through voluntary tools and incentives, should create key public-private partnerships and promote management. These recommendations have application beyond the Namibian energy sector, and the lessons learned here could be implemented in scenarios outside of it.

Background: Technology and innovation were envisaged as the key to competitive advantages and have become a hallmark of business life worldwide. Without technologies and invention practically, no organisation can survive. Thus, this required a clear understanding of how managing innovation and technology influenced business survival. This was much more explicit in an unprecedented and unavoidable competition in the business world environment, and particularly in the local government authorities’ context, it can be of great significance. Objectives: The main objective of this article was to provide a framework for assessing the effects of managing competitive advantage through technology and innovation in the context of metropolitan cities. This study also helped to provide an understanding of how technological innovation factors affected the performance of organisation effectiveness. Methodology: The methodology used in this study was mainly the secondary data analysis. A complete and thoroughly secondary data analysis process has been utilised as a research design and approach to complete this research work. This section rationalised the selection of the preferred methodology, dealt with data collection and data analysis and covered how data originated from secondary data sources. Results: One of the fundamental contributions of this investigation has been the development of a pool of valuable data in relation to managing technology and innovation for sustainable competitive advantage in the City Government of Taiwan as public sector. Furthermore and based on the results of reviewing and evaluating the relevant literature and theories taken together, this study has led to the development and proposal of a model, the conceptual framework. This developed conceptual framework reflected the bond between managing competitive advantage techniques through technology and innovation and business performances, which can be applied to different business sectors of the central government. The concept can also be applied to different businesses or to different countries confronted by similar challenges and issues of managing technology and innovation. Conclusion: This article posited the importance of managing competitive advantage through technology and innovation, particularly as an essential ingredient of competitive advantage for the local government authorities or metropolitans and municipalities.
