During the development of a severe accident at nuclearpower plantwith core melting, corium is formed. One main barriers preventing outflow into environment melt localization device or trap. The trap must accept and prevent parameters from exceeding critical values, ensuring its retention in controlled volume cooling. For this reason, traps are subject to serious requirements regarding cooling m...

Microwave-assisted gas-phase conversion on structured catalysts is emerging as a promising process intensification technology in the field of heterogeneous catalysis. The combination selective heating and catalytic materials induces temperature difference between heated sample surrounding void regions to avoid non-selective reactions. This operational principle allowed inhibiting thermal cracki...

The research revealed in the paper considers improvement of secondary treatment wastewater aerobic reactor to provide removal organics and nutrients. There were five types polymer biofilm carriers taken into account initially; however, two them decided not apply due technological reasons. main part was divided three substages investigate each type carrier. According literature review, optimal e...

This study investigated the interactive effects of temperature, residence time, and carrier gas flow rate on liquid fuel production through pyrolysis waste polyethylene (WPE) in a bench-scale semi-batch reactor. To enhance production, fifteen experiments were conducted based central composite design. The adaptive neural fuzzy model was adopted to establish relationship between operating conditi...

In this paper, we present BENCH (Biclusteringdriven ENsemble of Classifiers), an algorithm to construct an ensemble of classifiers through concurrent feature and data point selection guided by unsupervised knowledge obtained from biclustering. BENCH is designed for underdetermined problems. In our experiments, we use Bayesian Belief Network (BBN) classifiers as base classifiers in the ensemble;...

Abstract Background Microbial fuel cell (MFC) technology is a promising sustainable future energy source with renewable and abundant substrate. MFC critical drawbacks are anode surface area limitations electrochemical loss. Recent studies recommend thick biofilm growth due to the synergetic effect between microbial communities. Engineering prospect of MFC. In this study, electrode jacket dish (...

The digital model of the laboratory bench parts of digging deep rootstalk crops were established through adopting the parametric model technology based on feature. The virtual assembly of the laboratory bench of digging deep rootstalk crops was done and the digital model of the laboratory bench parts of digging deep rootstalk crops was gained. The vibrospade, which is the key part of the labora...

The methanation process is discussed as one way to chemically store renewable energy in a future system. An important criterion for its application the availability of compact, low-cost reactor concepts with high conversion rates decentralized use where produced. Current research focuses on maximization methane yield through improved temperature control exothermic reaction, which attempts avoid...
