Residual Minimization

The goal of model-based structural identification is to find suitable values of parameters that affect structure behaviour. To this end, measurements are often compared with predictions of finiteelement models. Although residual minimization (RM) is a prominent methodology for structural identification, it provides wrong parameter identification when flawed model classes are adopted. Error-domain model falsification (EDMF) is an alternative methodology that helps identify candidate models – models that are compatible with behaviour measurements – among an initial model population. This study focuses on the comparison between RM and EDMF for the structural identification of a steel bridge in Exeter (UK). Advantages and limitations of both methodologies are discussed with reference to parameter identification and prognosis tasks such as quantification of reserve capacity. Results show that the employment of RM may lead to wrong identification and unsafe estimations of reserve capacity.

Objective Socioeconomic Status

Based on the Reserve Capacity Model, this study investigated the associations of objective socioeconomic status and subjective social status with psychological health and the underlying psychosocial mechanisms in a population-based sample of Chinese migrants ( n = 15,999). Results showed that subjective social status was positively associated with life satisfaction and self-rated health through the mediation of psychological distress and perceived stress. Whereas education showed a very weak association with life satisfaction, income was directly associated with life satisfaction only. The findings suggest that reducing psychosocial vulnerabilities may be a potential impetus to eliminate socioeconomic health disparities among Chinese migrants.

Purpose. The aim of the work is to develop a method for estimating the capacity of garages for defrosting the transport system of an industrial enterprise. Research methods. In the course of the research methods of analysis and logic were used to evaluate scientific and technical publications related to the development and calculation of the capacity of technical devices of cargo stations and unloading complexes. Results. The method of estimating the capacity of defrosting garages of the transport system of an industrial enterprise is developed in the work. The developed method is based on the comparison of the calculated and required capacity of garages for defrosting of large unloading complexes of industrial enterprises. The need to introduce the reserve capacity of defrosting garages in connection with the influence of dynamic factors into the model is substantiated during the research. The scientific novelty lies in the development of a method for estimating the capacity of garages for defrosting the transport system of an industrial enterprise. Practical value. The developed method of capacity assessment allows to optimally, comprehensively synchronize the operation of defrost garages and unloading complex with processing capacity and thus increase the efficiency of management of the transport system of an industrial enterprise.
