Geo-tiles: manufacturing tiles from copper mine tailings using geopolymerisation by Makole, Karabo

“…Literature reports that such geopolymers were formed under similar conditions to geo-tiles but were characterised by SLRs ≈ 5.5 – 5.6. A design chart was developed to evaluate the breaking strength and MOR results for geo-tiles against limits dictated by International Organization for Standardization (ISO13006 (2018)) and South African National Standards (SANS1449 (2012)). …”

How do traditional donors respond when beneficiary countries set up their own aid agencies? : case studies of India, Brazil and South Africa by Teichmann, Christina

“…It argues that traditional donors perceive beneficiary countries with dedicated aid agencies as no longer in need of foreign assistance. In order to test this hypothesis and identify changes in the flow of aid, the research study compares official aid flow data for five selected traditional donors (France, Germany, the UK, the US and EU Institutions) to three emerging donor countries (India, Brazil and South Africa) before and after the establishment of dedicated aid agencies. …”

Non-intrusive efficiency estimation of induction machines under various power supplies by Gajjar, Chetan Sudhir

“…Coupled with vibration sensors used to determine a motor's speed, measured input voltages and currents are used to deduce a machine efficiency-load profile through the use of a modified evolutionary algorithm, the Non-Intrusive Efficiency Estimation using Population-Based Incremental Learning(NIEE-PBIL) algorithm. Five temporal load measurements are taken, centered around one thermally stable load point, to determine the machines efficiency profile from two equivalent circuit implementations; the Standard Circuit NIEE-PBIL and the Iron-Loss NIEE-PBIL.…”
