Abstract: With the rapid development of urbanization and modernization, people’s requirements for electric power are also consequently increasing. It is thus essential to ensure the sustainable and stable supply of power and maintain the safety performance of the power grid. Constructing a modern safety management system (SMS) can effectively improve power enterprises’ ability to respond to emergencies. To effectively evaluate the ability of electric power enterprises to resist risk impact, and the recovery and optimization ability after impact, this paper makes a systematic investigation of the SMS of power enterprises. It evaluates the safety resilience capabilities of the SMS from four basic elements of stability, redundancy, efficiency, and adaptability. A multilevel evaluation system of electric power enterprises’ safety resilience capacity consists of four first-level and 25 second-level indices. Then, an analytic hierarchy process (AHP) and matter-element extension (MEE) joint model—the AHP-MEE evaluation model of the resilience capacity of power enterprises—is proposed. A case study of electric power enterprise safety resilience evaluation is conducted using the proposed resilience evaluation index system and assessment model. The results showed that the provided model agrees with the actual situation and verified the index system and model for electric power enterprise safety reliability and applicability. Improved enterprise safety resilience recommendations are proposed accordingly based on the evaluation results. This work proposes a robust safety resilience capacity evaluation method in the face of upcoming new risks, thus building a good working foundation to construct a new power system with new energy sources.

Abstract: Thermal behavior of sulfide concentrates can give rise to many serious problems in its storage and transportation. In order to uncover the thermal behavior of sulfide concentrates, as well as obtain the kinetic parameters, four representative s les were tested using TG-DTG-DSC techniques in the presence of oxygen from 20? to 1000? and with three different heating rates of 5, 10, and 15? per minute. Meanwhile, corresponding activation energies of sulfide concentrates were also determined by the Coats-Redfern method (199.4-234.9 kJmol?1 for S le 1, 203.6-235.9 kJmol?1 for S le 2, 234.7-255.6 kJmol?1 for S le 3, and 199.7-254.9 kJmol?1 for S le 4). Results indicate that the heating rate is an important factor affecting the thermal behavior of sulfide concentrates. The peak temperature corresponding to the maximum mass loss rate of the ore s le at different heating rates is different and the sulfide concentrates at heating rate of 5? per minute is more prone to spontaneous combustion. Furthermore, this thermodynamic method was demonstrated to be effective for investigating and predicting the thermal behavior of sulfide concentrate and the activation energy index was reasonable for determining its spontaneous combustion tendency.

Abstract: Oil sludge is an organic solid waste in the petrochemical industry and improper treatment of oil sludge will cause environmental pollution. Pyrolysis is an effective way to realize its resource reuse. In order to understand the pyrolysis behavior and thermodynamic characteristics of oil sludge, four oil sludge s les from storage tanks were used as the research object, and pyrolysis experiments were carried out at heating rates of 5?, 10?, and 15? per minute under a nitrogen atmosphere. The kinetic parameters of pyrolysis of oil sludge are calculated by three equal conversion methods, Friedman method, Flynn-Wall-Ozawa method and Distributed activation energy model, and the most possible thermodynamic models for the main pyrolysis phase were analyzed and discussed by introducing the Malek method. The results show: high heating rate can promote the pyrolysis of oil sludge and in the pyrolysis stage, the apparent activation energy increases with the increase of the conversion rate. The apparent activation energy calculated by the Friedman method method is more reliable. The average apparent activation energies of the four oil sludge are 221.23, 84.71, 94.67, and 116.56 kJ/mol, respectively. The apparent activation energy and the pre-exponential factor are positively correlated, indicating that there is a kinetic compensation effect in the pyrolysis process. The thermodynamic models of the four oil sludge s les are all 3-D diffusion models, but their integral functions are different. The research results can provide theoretical support for the industrialization, harmlessness, and resource utilization of oil sludge pyrolysis.

Abstract: This study aims to analyze the scientific research progress on human fatigue assessment (HFA) by using a bibliometric method, which was conducted a systematic analyses of 28,028 scientific papers about HFA from the Web of Science database, and the results were discussed from the following perspectives: temporal distribution, geographical distribution, discipline distribution, and key words distribution. In addition, this analysis also provides the network of author co-citation and key words. The results are summarized as follows: 1) the number of papers about HFA increased rapidly since 1990s 2) The United States is a high-yield, high-cited country with 36.70% of the world's total literatures, and whose average citation index on HFA research is 47.89 per paper China is the developing country with the largest number of publications, but its total citations and average citations are backward, only with an average of 21 citations per article 3) The assessment of human fatigue shows the development trend of multidisciplinary intersecting 4) There is a relative lack of cooperation among the world's leading scholars the Dutch Gijs Bleijenberg is the most published scholar in the world, who have 108 articles on HFA research the American scholar David Cella has the most influential article, with an h-index of 36 the distribution of Chinese scholars is relatively scattered, and no one has written more than five articles 5) All of countries in the world had the same research topics, "muscle fatigue" is an important part of the HFA China needs to pay more attention to the fatigue assessment associated with cancer. The results of the analysis can be used to enhance our understanding of HFA research and support further research in this area.
