In this work, Particle Swarm Optimization (PSO) based intelligent controller design technique is attempted for a nonlinear spherical tank process. The search process is guided by an objective function, which considers the minimization of some key parameters such as Integral Square Error (ISE), Integral Absolute Error (IAE), and settling time (ts) of the process under study. The proposed control...
Background and purpose: One of the solutions for sludge production is to reduce that via decreasing the yield coefficient by oxic-settling anoxic process with different oxidation reduction potential (ORP) in sequencing batch reactor (SBR) activated sludge. Materials and methods: We used 2 SBR reactors (20 L volume) that were controlled online. At a steady state in reactors, some parameters suc...
The objective of this study was to evaluate the growth of green algae Chlorella sp. on wastewaters sampled from four different points of the treatment process flow of a local municipal wastewater treatment plant (MWTP) and how well the algal growth removed nitrogen, phosphorus, chemical oxygen demand (COD), and metal ions from the wastewaters. The four wastewaters were wastewater before primary...
<p>Process industry needed a fast executed automatic control system capable of handling uncertain, vague problems and nonlinear variables. Liquid level is one the emerging getting interest technical experts in area control. This paper based on fuzzy logic strategy to maintain stabilize liquid tank that deals with pumping tanks as well regulating pushing off into another tank. Fuzzy contro...
Under the EU Directive 2004/28/EC, an environmental risk assessment of new veterinary medicinal products is required. Given the nature of risk assessment for new applications, there is a need to model exposure concentrations. Critical evaluations are essential to ensure that the use of models by regulators does not result in the propagation of misleading information. The empirical validations o...
Quentin Skinner is an intellectual historian known for his pioneering work on early-modern European political thought. He was educated at Bedford School and Gonville and Caius College, Cambridge. Author of such works as The Foundations of Modern Political Thought (1978) and Visions of Politics (2002) he served as the Regius Professor of History at the University of Cambridge, and currently as t...
