However, most multivariate statistical process monitoring (MSPM) methods are based on the assumption that the process has only one nominal mode. When the process data contain different distributions, they may not function as well as in single mode processes. To address this issue, an improved partial least squares (IPLS) method was proposed for multimode process monitoring. By utilizing a novel local standardization strategy, the normal data in multiple modes could be centralized after being standardized and the fundamental assumption of partial least squares (PLS) could be valid again in multimode process. In this way, PLS method was extended to be suitable for not only single mode processes but also multimode processes. The efficiency of the proposed method was illustrated by comparing the monitoring results of PLS and IPLS in Tennessee Eastman(TE) process.展开更多

The development of forest biomass briquetting densification fuel, which has a high calorific value, can ease the energy shortage in China. But the molding technology is still at the primary stage with many questions unresolved, such as unequal distribution of resources, imperfect technology and an inadequate mechanism of market supply and demand. There are no consistent production and quality standards to refer to, which seriously hinder the industrialization of biomass molding technology. Hence, it is imperative to speed up the formulation of production standards of biomass briquetting densification fuel which not only conform to international standards, but are in accordance with national condi- tions in China. Drawing on the standards of biomass briquetting densification fuel in Europe, a standard system should be concerned with raw material collection, transport and storage of the end products, terminology, denomination and classification of molding equipment, as well as with technical conditions, testing methods, safety and environmental protection. The establishment of a stan- dard system is useful for the development of a healthy, orderly and sustainable biomass fuel industry.展开更多

Controlling robots with spoken natural language has become expectable. With the reliability problem of this kind of control in mind a confirmation process of natural language instruction should be included before carried out by the robot autonomously and the prototype dialog system was designed thus the standardization problem was raised for the natural and understandable language interaction. In the application background of remotely navigating a mobile robot inside a building with Chinese natural spoken language considering that as an important navigation element in instructions a place name can be expressed with different lexical terms in spoken language this paper proposes a model for substituting different alternatives of a place name with a standard one (called standardization). First a CRF (Conditional Random Fields) model is trained to label the term required be standardized then a trained word embedding model is to represent lexical terms as digital vectors. In the vector space similarity of lexical terms is defined and used to find out the most similar one to the term picked out to be standardized. Experiments show that the method proposed works well and the dialog system responses to confirm the instructions are natural and understandable.展开更多

The dry paste yield was utilized as the evaluation criterion, in conjunction with the actual production conditions. Thin layer chromatography was employed to identify Radix Astragali, Lycii Fructus, Herba Dendrobii, and Rhizoma Polygoni Cuspidati. Ethanol served as the solvent for the determination of ethanol-soluble extractives using the cold immersion method.[Results] The preparation process was conducted as follows: the specified quantity of medicinal materials was combined with water for extraction purposes, performed in two separate stages. In each stage, eight times the amount of water was added. The first extraction lasted for 1.5 h, while the second extraction was completed in 1.0 h. The resulting liquid was then concentrated into a thick paste with a relative density ranging from 1.25 to 1.30 at a temperature of 60 ℃. The thin-layer chromatography analysis of Radix Astragali, Lycii Fructus, Herba Dendrobii, and Rhizoma Polygoni Cuspidati demonstrated distinct spots, effective separation, and the absence of interference from negative samples. Additionally, the ethanol-soluble extractives yielded a minimum of 8.0% in terms of dry weight.[Conclusions] The preparation process for Rougan Huaxian ointment is both stable and feasible. Furthermore, the quality standards established for this preparation are unique and reproducible, thereby facilitating effective quality control.展开更多

The dry paste yield was utilized as the evaluation criterion, in conjunction with the actual production conditions. Thin layer chromatography was employed to identify Radix Astragali, Lycii Fructus, Herba Dendrobii, and Rhizoma Polygoni Cuspidati. Ethanol served as the solvent for the determination of ethanol-soluble extractives using the cold immersion method.[Results] The preparation process was conducted as follows: the specified quantity of medicinal materials was combined with water for extraction purposes, performed in two separate stages. In each stage, eight times the amount of water was added. The first extraction lasted for 1.5 h, while the second extraction was completed in 1.0 h.

The thin-layer chromatography analysis of Radix Astragali, Lycii Fructus, Herba Dendrobii, and Rhizoma Polygoni Cuspidati demonstrated distinct spots, effective separation, and the absence of interference from negative samples. Additionally, the ethanol-soluble extractives yielded a minimum of 8.0% in terms of dry weight.[Conclusions] The preparation process for Rougan Huaxian ointment is both stable and feasible. Furthermore, the quality standards established for this preparation are unique and reproducible, thereby facilitating effective quality control.
文摘With the continuous development of society, the content of accounting standards will change accordingly. In this context, relevant personnel should also pay attention to the impact of accounting standards on accounting supervision at all times, so as to effectively promote the continuous innovation of the accounting supervision system, better adapt to the changes in the content of accounting standards, and promote the further development of enterprises. Based on this, this paper first describes the positive impact of the new accounting standards on accounting supervision, and then describes the negative impact of the reform of accounting standards on accounting supervision from four aspects, which can be used as a reference for relevant people.
文摘Objective: to explore the application value of standardized nursing process of PICC in patients with tumor undergoing chemotherapy and catheterization. Methods: cases were selected from January 2019 to December 2020. Case type: PICC catheter for tumor chemotherapy;Total cases: 82;Grouping method: random envelope method;Group: reference group and observation group;Number of groups: 41;Nursing methods: routine nursing and standardized nursing process of PICC;Comparative items: nursing satisfaction, complications and phlebitis. Results: the nursing satisfaction of the observation group and the reference group was 97.56% and 8.48% respectively, with significant difference (χ2 = 6.1157). The incidence of complications in the observation group and the reference group was 7.32% and 24.39% respectively, with significant difference (χ2 = 4.4794). The incidence of phlebitis in the observation group (grade 0: 73.17%, grade 1-2: 24.39%, grade 3-4: 2.44%) was lower than that in the reference group (grade 0: 34.15%, grade 1-2: 48.78%, grade 3-4: 17.07%). there was a significant difference between the groups (χ2 = 12.5550, 5.2564, 4.9865), with statistical significance (P < 0.05). Conclusion: the implementation of PICC standardized nursing process for tumor chemotherapy patients can improve the incidence of phlebitis and reduce complications. The nursing effect is significant, which is worthy of clinical reference.
文摘Objective: to effectively improve the standardized emergency care procedures for patients with ST-segment elevation myocardial infarction. Methods: Seventy-two patients with ST segment elevation myocardial infarction who were admitted to our hospital from January 2020 to December 2020 were selected as the main subjects of this study. They were divided into the control group/observation group. Among them, the control group received routine emergency care while the observation group received standardized emergency care procedures based on the routine emergency care measures, so as to compare the differences in the care procedures and patient care quality of the two patients during the emergency treatment. The difference was large, and the condition of the observation group was better. Finally, through the analysis of two groups of patients after treatment, and then investigate the family members and patients' satisfaction with care. The clinical results showed that the efficacy of 88.9% in the observation group was significantly superior to 66.7% in the control group, and the difference was statistically significant (P < 0.05). Conclusion: through analyzing the different nursing procedures of patients in two groups, it was found that the standardized emergency nursing procedures shortened the basic treatment time of patients and improved the success rate of rescue, providing a larger space for the treatment of patients, and the families were also satisfied with it.
