the removal of cd2+ and pb2+ ions from wastewater using p-tert-butyl-calix[4] arene was investigated in terms of initial ph, initial concentration, adsorbent dosage, contact time and temperature. the maximum adsorption occurred at the ph value of 6. the adsorbent studied exhibits high efficiency for cd (ii)and pb (ii) adsorption and the equilibrium states could be achieved in 10 min. adsorption...

Many real-world domains exhibit rich relational structure and stochasticity and motivate the development of models that combine predicate logic with probabilities. These models describe probabilistic influences between attributes of objects that are related to each other through known domain relationships. To keep these models succinct, each such influence is considered independent of others, w...

Absrract This paper presents a practical application of the conventional multi-loop control method for the temperature control of a television glass furnace. To control the temperature of the TV glass furnace, major input-output variables are selected, and simple FirstOrder-Plus-Dead-Time(F0PDT)models are established with the process experimental data. Based on the FOPDT models, a multi-loop. c...

This work carries out a comparative analysis of the stability robustness of PI and PI controllers when applied to first order plus time delay plants. An analytical result shows that both controllers have exactly the same region of feasible frequency specifications. Nevertheless, the robustness of both controllers is quite different. Depending on the set of frequency specifications and the non i...

The aim of this paper is to implement controllers based on soft computing techniques in real time for a non-linear process. The process taken up for study is to control the level in a conical tank setup using cost effective data acquisition system. The system identification of this nonlinear process is done using black box modeling and found to be First Order Plus Dead Time (FOPDT) model. Then ...
