. The aim of this work is to determine a suitable adsorbent based on the iron oxide and manganese oxide for the removal of W from molybdate solution. In addition, the effects of different experimental... separation results without preadjusting the initial solution pH, which simplifies the operation and expands applicability of processing solution. The feed concentration experiments show that this adsorption......

School of Metallurgy and Environment, Central South University, Changsha 410083, China Received 27 July 2016; accepted 21 June 2017 Abstract: A computational thermodynamics model for the oxygen bottom-blown copper smelting process (Shuikoushan, SKS process) was established, based......
variable axis and hence obtaining the structural responses. To reduce the computational effort of the evaluation of limit state function, an ANN surrogate is trained based on the sampling points from...) is performed to obtain the failure probability, based on the trained ANN surrogate. Three numerical examples are used to illustrate the accuracy and efficiency of the proposed method. Key words: high......
, the amount of solid phase in the fluid is determined using the temperature ratio. Then, based on critical solid fraction, Fs, and coherent solid fraction, FCr, the mushy zone is divided into three parts... to avoid dividing zero. Equation (10) represents the frictional dissipation in the mushy zone based on Carman–Koseny equation, which is obtained from Darcy model. In the third part, local solid fraction......
, a two-dimensional (2D) general predictive iterative learning control (2D-MGPILC) strategy based on the multi-model with time-varying weights was introduced for optimizing the tracking performance of desired temperature profile. This strategy was modeled based on an iterative learning control (ILC) algorithm for a 2D system and designed in the generalized predictive control (GPC) framework. Firstly......
for domestic and foreign scholars [3, 4]. In this process, the restoring force model is a practical mathematical model, and is based on a large number of experiments about the recovery force and deformation... of lateral displacement on the top of all frames under the cyclic loading. Based on Fig. 5 the following observations can be noted: Clearly, all specimens’ hysteresis curves show inconspicuous......
and is a kind of weighted mean that surrounding points of samples are considered in U value determination. However, it is able to separate the different anomalies based on only one variable. The main aim... based on several variables. Therefore, at the first step, the optimum p is calculated in p-norm distance and then U-statistic method is applied on p-norm distance values of the samples because p-norm......
