Transarterial chemoembolization (TACE) has been widely used for hepatocellular carcinoma. Reducing hypoxia in the tumor microenvironment after TACE remains a challenge as tumor progression is common in post‐TACE patients due to the hypoxic tumor microenvironment. In this study, melatonin loaded on p(N‐isopropyl‐acrylamide‐co‐butyl methylacrylate) (PIB‐M) was used for tumor embolism. Two types of human...
Mission failure evolution is a unique aspect of complex human-machine system (CHMS), which contains failure regularity and directs emergent reconfiguration measures. Oriented to all varieties of system components, an analysis of how the parts are connected and contribute to CHMS failure is necessary. Prior work paid more attention to system design with the law of system normal operation, where a single...
Recommender systems represent user preferences for the purpose of suggesting items to select or examine. In petroleum drilling safety check, there are many items (e.g. tool misused and warning signs ignored) to be checked during one day. However, existing recommender systems seldom apply time series and interaction methods for the issue. In this paper, we propose a recommender system with two techniques...
This paper presents a composite element evaluation model of urban mountain road safety. First, create multi-level indicators of road safety, which are divided into the cost, benefit, fixed and interval. Second, build evaluation matrix of composite element for mountain city road traffic safety, use information entropy theory to describe uncertainty of portray Indices in order to calculate the composite...
Prognostics and health management (PHM) is a methodology that permits the reliability of a system to be evaluated in its actual life cycle conditions in order to predict when and where failures will occur and to mitigate system risks. In this paper we discuss the benefits of prognostics in systems. These benefits relate to system design and development, reliability, safety, maintainability, logistics...
Coal mine safety management is one of the most important basic job, and related with almost all coal production systems. It analyzed characteristics of coal mine data which not only show data volume large, information sources excessively, but also is dynamic, random and fuzzy. It stressed that application of data mining technology to coal mine safety is an important way to improve mine safety work...
