Comparative Analysis of Frequency Ratio, Analytical Hierarchy Process, and Logistic Regression Methods in Selecting the Location of Rural Dwellings: the Case of Keban Stream Basin (Elazığ)

Coğrafya Dergisi, 2022
Rural areas in Turkey are undergoing significant transformations, but not as much as cities. Rural areas are evolving in many aspects, including land use, economic structure, and lifestyles. Rural housing is one of the most important indicators of change.

Detecting extreme mass ratio inspirals with LISA using time-frequency methods II: search characterization [PDF]

, 2005
The inspirals of stellar-mass compact objects into supermassive black holes constitute some of the most important sources for LISA. Detection of these sources using fully coherent matched filtering is computationally intractable, so alternative ...

The X-ray Outburst of H1743-322: High-Frequency QPOs with a 3:2 Frequency Ratio

, 2004
We observed the 2003 X-ray outburst of H1743-322 in a series of 130 pointed observation with RXTE. We searched individual observations for high-frequency QPOs (HFQPOs) and found only weak or marginal detections near 240 and 160 Hz.

Identification of Dominant Controlling Factors and Susceptibility Assessment of Coseismic Landslides Triggered by the 2022 Luding Earthquake

Remote Sensing
Coseismic landslides are geological events in which slopes, either on the verge of instability or already in a fragile state, experience premature failure due to seismic shaking.

A Nonlinear Stacking Evaluation Model of Landslide Susceptibility Based on Key Geological Factors

Redai dili
Geological conditions restrict the occurrence and development of slope collapse from many aspects. The occurrence proportion of slope collapse in granite areas is 84.7%, which is a key factor in the evaluation of hill collapse susceptibility.
