The theory of resilience has been studied in numerous disciplines as interdisciplinary research. It involved different fields of studies such as psychology, psychopathology, human development, and environmental hazard. Nevertheless, further research on the extension theory of resilience is needed in the field of the built environment. The study aims to explore the position of resilience in the built environment, specifically in urban agriculture practices. The objectives are (i) to explain the meaning of resilience, (ii) to describe the evolution of resilience concerning the built environment, and (iii) to determine the construct of resilience in urban agriculture practices. This study employs qualitative research through a scoping review and systematic literature review by three phases encompasses identification, screening, and eligibility of secondary sources. A new definition and comprehensive explanation of the evolution of resilience are proposed subject to the built environment. .....

There are many types of controllers had been used to control Autonomous Underwater Vehicle (AUV) such as Proportional Integral Derivative (PID), Linear Quadratic Regulator (LQR), state feedback linearization, integrator backstepping, and Sliding-Mode Control (SMC). However, for PID and SMC in particular, it is difficult to determine the optimal control design parameters. The objective of this study is to design and develop a responsive motion control system with optimal parameters for an AUV. The contribution of this paper is in term of introducing a filter to smooth reference signal and proposing a brute forcing technique to find optimal controller parameters. The methodology starts with modeling the AUV, estimating the unknown parameters from a real AUV model, designing a control system based on PI and SMC methods, and finally optimizing the controller parameters. The controller design was onto controlling surge speed using PI, heading using SMC, and diving using SMC. Simulation-wise.....

This article contains the results of experiments to recover gold from complex mineral raw materials containing more than 15 % arsenic. Laboratory tests showed that standard cyanidation recovers only 26,4 % of gold into the solution. Additional oxidizing reagents used increase the leaching efficiency and enable to recover more than 40 % of gold during subsequent cyanidation. The efficiency has been established for replacement of cyanide with thiourea and thiosulfate solutions. 79,5 %, i.e. the maximum recovery rate, was found in the experiment with preliminary oxidation with T. Ferrooxidans, a bacterial culture, followed by leaching with a thiourea solution. ? 2021, Faculty of Metallurgy. All rights reserved...
