SEISMIC MOTION INPUT METHODS OF VISCOUS-ELASTIC BOUNDARY AND NUMERICAL SIMULATION OF SEISMIC RESPONSE ON LARGE DIAMETER TUNNELS

Seismic motion input methods of viscous-elastic boundary and numerical simulation of seismic response on large diameter tunnels

To determine the selection of input wave field at the bottom of the viscous-elastic boundary, and study the seismic response of two parallel large-diameter shield tunnels, corresponding numerical models were established for analysis.First, through the study of wave method for seismic motion input of viscous-elastic boundary, several different wave

Dynamic magnetic resonance imaging; reliability of assessment and correlation with clinical findings of pelvic organ prolapse

Introduction: Pelvic floor dysfunction and prolapse affect about 50% of women past middle age.Failure to recognize the complex set of pelvic floor defects in individuals leads to most postsurgical failures.Diagnosis and grading of pelvic floor dysfunction is primarily done by physical examination.Imaging does not have yet an established role in the

Measurement and Influencing Factors of Economic Resilience over a Long Duration of COVID-19: A Case Study of the Yangtze River Delta, China

The COVID-19 pandemic put forward a new test for an economic resilience study.Its long-term and diffusive spatiotemporal characteristics suggest that we need to pay attention to the resilience and spatial heterogeneity of cities over a longer period.This paper applied SARIMA and the performance curve to measure the economic resilience of each city

Postmodernism and Rethinking the Concept of Crime

Defining the concept of crime is the starting point in the criminal thought.Basically, any view taken on the concept of crime formulates the other fundamental criminological concepts (such as the criminal and etiology) as well as basic concepts of Stationery criminal policy system (such as justice, criminalization and prevention).In the light of th
