Abstract In this work, the biochar adsorbent carboxymethyl cellulose (CMC), was prepared from pyrolysis (600 °C, 120 min) of chicken manure for removal methyl orange (MO) aqueous solution, and its physicochemical properties were characterized by scanning electron microscopy (SEM) Fourier transform infrared spectra (FTIR). The experimental parameters including agitation speed, initial solution pH, dosage contact time on adsorption MO onto CMC investigated in batch experiments. kinetic...
As an efficient clean energy, natural gas hydrate (NGH) has become a hot topic in recent researches. Since 1990s, China made great achievements and progress NGH exploration the South Sea (SCS), including determination of favorable distribution areas strata thickness, identification dual source for accumulation, evaluation prospective contents, verification widespread existence, confirmation technical recoverability resources. However, there are three major challenges studies. First, all 24...
Efficient shelf-space allocation can provide retailers with a competitive edge. While there has been little study on this subject, is great interest in improving product the retail industry. This paper examines practicable linear model for optimizing allocation. It extends to address other requirements such as groupings and nonlinear profit functions. Besides providing network flow solution, we put forward strategy that combines strong local search metaheuristic approach space flexible...
The vehicle routing problem with time windows (VRPTW) is an important in logistics. to serve a number of customers at minimum cost without violating the customers’ time-window constraints or vehicle-capacity constraint. In this paper, we propose two-stage algorithm for VRPTW. first minimizes vehicles ejection pool hold temporarily unserved customers, which enables go through infeasible solution space. Then it total travel distance using multi-start iterated hill-climbing classical and new...
The safety and reliability of high-speed trains depend on the brake disc. In order to improve lifetime disc reduce waste resources, a coating with higher microhardness well wear resistance is urgently needed. effect chromium content microstructure, NiCr has been studied. Nano-crystalline Ni coatings superior mechanical properties were successfully prepared 30CrNiMo steel substrate by pulse current electrodeposition method. inclusion formic acid sodium citrate was found significantly expedite...
Because stochastic gradient descent (SGD) has shown promise optimizing neural networks with millions of parameters and few if any alternatives are known to exist, it moved the heart leading approaches reinforcement learning (RL). For that reason, recent result from OpenAI showing a particular kind evolution strategy (ES) can rival performance SGD-based deep RL methods large provoked surprise. This is difficult interpret in part because lingering ambiguity on how ES actually relates SGD. The...
This work investigated the pH effect on ozonation and carbon-assisted processes, where methylene blue (MB) was employed as model compound. Kinetic study quantitative description reaction pathway, i.e. molecular ozone attack hydroxyl radicals (HO) oxidation, were accomplished to evaluate of process control for ozonation. The HO route MB decolorization intensified with increasing become even comparable reached up 11 (θ=1.14), this trend can also be reflected by comparative analysis detected...
This paper addresses single and multiple container loading problems. We propose to use dynamic prioritization handle awkward box types. The type with a higher priority will be packed onto lower surfaces of the container, or in earlier containers. solution found one iteration algorithm is analyzed, priorities are updated used next iteration. Our outperformed all previous methods using standard benchmark data sets. existing test for problem deficient supplemented them by generating new...
The effect of Lanthanum content on the microstructure and mechanical properties Al–5Mg–2Si-0.6Mn alloy in squeeze casting was studied. characterized by scanning electron microscope (SEM) X-ray diffractometer (XRD). were tested tensile testing machine. results show that rare earth has a significant secondary dendrite spacing volume fraction α-Al + Mg2Si eutectic phase, both which increase at first then decrease with Lanthanum. When is 0.05 wt.%, maximum phase 45.09%. minimum 25.85 μm....
