Dataset for damage detection retrieved from a monitored bridge pre and post verified damage.

The Vänersborg Bridge in southwest Sweden is a single-leaf bascule bridge carrying railway traffic over a canal. The load consists of passing commuter trains, occasional freight trains and leaf openings to allow ships to pass on the canal. The bridge constructed from 1914 to 1916 was built by riveted truss members in steel. Over the years, several assessments and maintenance actions have been performed to keep the bridge in service. During autumn 2021, a long-term monitoring campaign was initiated with the installation of sensors to register the load effect and possible changes in the behaviour. In March 2023, the cloud-based service employed detected an abrupt change of behaviour. An emergency inspection revealed a large crack in one of the truss members in the counter-weight part. The published dataset contains sensor data from 64 registered bridge openings, comprising accelerations, strains, inclinations, and weather conditions. Data from before the fracture, during, and after are provided. During the bridge opening events, the data was recorded continuously with a sampling rate of 200 Hz. The evidence of damage in a real case scenario makes the dataset valuable for testing and evaluation of data-driven routines for infrastructure surveillance.

Assessing Key Linguistic Dimensions of Ruptures in the Therapeutic Alliance.

Over the past two decades, therapeutic alliance research has increasingly focused on understanding the process by which the alliance is ruptured and repaired. This paper is the first to explore how alliance rupture segments from psychotherapy sessions differ from non-rupture segments on key dimensions of the referential process. A sample of 27 psychotherapy sessions were scored using a measure designed to identify rupture from non-rupture segments. These segments were then scored for key linguistic dimensions of the referential process. During ruptures patients manifested a referential process marked by a decrease in emotional engagement, an increase in a measure of distancing, and an increase in negation as compared to non-rupture segments. Therapists show similar patterns but, in addition, manifest a language pattern that suggests that during ruptures, therapists are attempting to make sense of, and self-disclose, aspects of their inner experience. Implications for research and clinical work are explored.
