Application of Polynomial Regression Analysis in Evaluating the Techno-Economic Performance of DSPV Transformers

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 2, Page # 458–463, 2021; DOI: 10.25046/aj060252
Abstract:

To this extent, the delineation of techno-economic evaluations for transformers becomes more intricate through a lens of Distributed Solar Photovoltaic (DSPV) market in South Africa. Essentially, the transformer price and loss evaluation techniques should be tailored for calculating the Total Ownership Cost (TOC) of transformers facilitating decentralized energy systems. In South Africa, the traditional coal…

Assessment of Transformer Cellulose Insulation Life Expectancy Based on Oil Furan Analysis (Case Study: South African Transformers)

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 6, Page # 29–33, 2021; DOI: 10.25046/aj060605
Abstract:

The ageing of oil-immersed power transformers triggers several defects and damages in the insulating materials, particularly in the cellulose insulation. The decomposition of the cellulose paper produces dissolved gases into the insulating oil, in which the Dissolved Gas Analysis (DGA) of the oil samples can provide insights to incipient faults sustained by the transformer as…

Overcome Discrimination: A Logistic Regression with 10-year Longitudinal Investigation of Emo Kids’ Facebook Posts

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 5, Page # 637–644, 2020; DOI: 10.25046/aj050578
Abstract:

This study primarily aims to identify the factors that helped emo kids in 2010 move through the emo-identity discrimination and be able to obtain a certain level of achievement. Facebook is the social network that allows users to track friends’ posts back over 10 years. Content analysis was conducted by using two coders to rate…

Modeling Watershed Health Assessment for Five Watersheds in Lampung Province, Indonesia

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 1, Page # 99–111, 2021; DOI: 10.25046/aj060111
Abstract:

A healthy watershed is important not only for the ecosystem but also for human socioeconomic activities. Therefore, a compatible assessment model is required to recognize watershed health. In Indonesia, the watershed health assessment is directed by the Ministry of Forestry regulation number 60/2014. A critic might be posed to this directive for not including the…
