The gas-injection BF is a new iron-making technology with injecting gas instead of the traditional pulverized coal injection and recycling top through gasifier. Compare BF, there larger amount reducing such as CO H2 in BF. Effect addition on reduction kinetics iron oxides was investigated by Thermogravimetric Analysis. result shows that rate rise increase both temperature content. By contrast content increasing from 10% to 15% at 700°C 900°C, improvement more obvious when 20% same...
Self-supervised learning (SSL) is vulnerable to backdoor attacks, while the downstream classifiers based on SSL models inevitably inherit these backdoors, even when they are trained clean samples. Despite proposal of several methods defense against few remain that can be used effectively defend various attacks maintaining high performance model. In this paper, discovery unlearning any trigger enhances overall robustness model, a novel, efficient, and straightforward approach proposed address...
This paper aims to evaluate the feasibility and performances of a novel hybrid solar–gas system, which provides electric power cooling. By using Ebsilon (V15.0) software, operation, advanced exergic economic analyses this system are conducted. The analysis results show that total energy efficiency 96.0 MW 45.8%. solar contributes an 9.0 MW. maximum cooling load is 69.66 loss whole 119.1 44.6%. combustion chamber (CC) has (56.5 MW). direct steam generator (SDSG) 28.5 36.2%. For air compressor...
Rail corrugation is a serious problem in railway transportation system, aggravating the operational risk and shortening lifetime of train–track system. In order to ensure safety reliability detection rail very important. Thus, this study systematically summarizes recent research progress corrugation. First, introduces definition classification criteria. Then, formation mechanism analyzed detail, its adverse consequences are investigated. Further, several main methods, which...

In dry machining, the tool-chip interface temperature is a critical factor affecting engineering performance of WC–Co tools. As variation cutting tool in machining similar to that annealing process, effect on mechanical properties materials can be studied by means experiment. this paper, series experiments ultrafine-grained were conducted, and effects holding time materials, including flexural strength, hardness fracture toughness, investigated. The results show under experimental...
For the blast furnace iron-making process which depends on coke seriously and is largest CO2 emission source in iron steel industry, a novel technology integrated co-gasification of coal-COG-BF top gas investigated examined its potential energy conservation reduction. The mathematical model whole established based mass heat balance principles. And typical operation analyses for are demonstrated by this model. results indicate that it takes about 4 times unsteady caused recycling BF to reach...
Abstract This article investigated the effects of Ni loading on performance Ni/SiO 2 catalysts for selective hydrogenation biphenyl (BP) to cyclohexylbenzene (CHB). The were characterized by techniques thermogravimetric analysis, X‐ray powder diffraction, N ‐physisorption, scanning electron microscope, inductively coupled plasma‐atomic emission spectroscopy, transmission H temperature‐programmed reduction. It was found that under given reaction conditions, BP conversion showed an increased...
Functionally gradient WC-Co composites having a Co depleted surface zone and not comprising the h phase can be manufactured via carburizing process. During carburizing, besides process parameters, microstructural parameters of materials, such as WC grain size content, also have significant influences on formation structure. In this study, effects particle content structure within hardmetals been studied, based series experiments materials with different sizes cobalt contents. The results...
Abstract The effects of the simultaneous injection MgO and magnesite powder on combustion coals, properties primary slag, softening-melting burden were investigated. There four aspects to results that we obtained. First, showed catalytic activity for dehydrogenation carboxyl group removal from coal; as a result, with increasing MgO, ratio pyrolysis coal investigated improved. Notably, when content increased 0% 3.21%, 67.75% 75.73%. Secondly, distribution in slag sample was close standard...
The primary objective of this study is the development Cu/Nb composite materials for Superconducting Radio-Frequency (SRF) applications under extreme service conditions characterized by a strong RF electromagnetic field, extremely low temperatures, and relatively heat loss. A novel integrated manufacturing approach proposed, which combines cold-sprayed AgCuTi alloy as an intermediate coating on Nb surface electroplated Cu layer with subsequent treatment brazing effect. This strategy aims to...
The rapid development of deep learning (DL) models has been accompanied by various safety and security challenges, such as adversarial attacks backdoor attacks. By analyzing the current literature on defenses in DL, we find that ongoing adaptation between attack defense makes it impossible to completely resolve these issues. In this paper, propose situation is caused inherent flaws DL models, namely non-interpretability, non-recognizability, non-identifiability. We refer issues Endogenous...
