A Comparison of the Predictive Validity of Self-Esteem Level and Directly Measured Self-Esteem Stability in the Temporal Prediction of Psychological Distress

Frontiers in Psychology, 2020
In contrast to the widely used assessment approach in which self-esteem stability is measured as the standard deviation of repeated measurements, direct measurements of self-esteem stability have hardly ever been implemented in longitudinal studies.

Latin Hypercube Sampling Method for Location Selection of Multi-Infeed HVDC System Terminal

Energies, 2020
Owing to the stochastic states of power systems with large-scale renewable generation, the impact of high-voltage direct current (HVDC) systems on the stability of the power system should be examined in a probabilistic manner.

Economic and fault stability analysis of geothermal field development in direct-use hydrothermal reservoirs

Geothermal Energy, 2021
The installed capacity of geothermal systems for direct use of heat is increasing worldwide. As their number and density is increasing, the their interaction with subsurface faults becomes more important as they could lead to safety risks from induced ...

Evolution of ship damage stability assessment—Transitioning designers to direct numerical simulations

Ocean Engineering, 2023
Theory and application of damage stability followed over the years two dissociated paths: static assessments and dynamic simulations. The first approach, being easy to apply and understand, has been preferred by ship designers and regulators; the second, more advanced and first-principle oriented, has been mainly reserved for research or high-level ...

Direct Method for Transient Stability Assessment of a Power System with a SSSC

Journal of Computers, 2007
This paper proposes the energy function of a power system with a Static Synchronous Series Compensator (SSSC). They make it possible for the direct method to acquire the transient stability or critical clearing time assessment of a power system. The proposed energy function of a power system with a SSSC is first derived and then it is used for SSSC ...
