A Study on the Coastline Extraction and Coastal Change Analysis Using Sentinel-2 Imagery in Funafuti, Tuvalu

open access: yesRemote Sensing
Temporal alterations in coastlines depict the significant changes in coastal areas, driven by both natural processes and human activities. For island nations, monitoring of the coastline is essential due to their vulnerability to such impacts.

A comprehensive study on damage prediction of pile foundations of inclined high rise buildings and the effect of compaction grouting

open access: yesScientific Reports
The construction of high-rise buildings in complex soft soil layers is highly prone to uneven settlement of the foundation, which in turn induces building tilting. In severe cases, it can lead to overall collapse accidents.

Effects of probability and duration of reinforcement on choice behavior in discrete trial intervals [PDF]

open access: yes, 1975
Pigeons were trained to peck at blue or amber keys presented simultaneously in discrete trials. In the first experiment, there were seven discrete trials with reinforcement scheduled probabilistically every seventh trial in the reinforcement interval ...

Grouting uplift for structural rectification of a high-rise building

open access: yesScientific Reports
Under poor stratum conditions, buildings are particularly susceptible to uneven settlement, which constitutes a significant threat to structural safety. Foundation grouting uplift is generally recognized as an effective method for addressing such issues.

Partial reinforcement and resistance to extinction [PDF]

open access: yes, 1987
Schoenfeld (1950) proposed that manipulations of rates of reinforcement have two conflicting effects on resistance to extinction. Leaner schedules reinforce behavior less frequently, which results in less resistance to extinction.
