Brittleness index evaluation of gas-bearing sandstone under triaxial compression conditions
Geomechanics and Geophysics for Geo-Energy and Geo-Resources, 2023 Brittleness is a critical property in gas-bearing rock excavation and reservoir fracturing. This paper analyzes the three types of brittleness indices in detail, proposes new indices, and conducts relevant conventional triaxial tests for analysis.

Physiological Parameters Variation Based on the Sensory Stimuli used by a Robot in a News Reading Task [PDF]
2018 27th IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN), 2018 Enabling robots to determine how physiological parameters vary in relation to the profile of an individual can lead to a better adaptation of the behavior of the robot to the needs of the individual it interacts with. This paper investigates how physiological parameters (i.e., blinking, galvanic skin response (GSR), facial temperature variation) vary ...

Fractional variational principle of Herglotz for a new class of problems with dependence on the boundaries and a real parameter [PDF]
Journal of Mathematical Physics, 2020 The fractional variational problem of Herglotz type for the case where the Lagrangian depends on generalized fractional derivatives, the free endpoints conditions, and a real parameter is studied. This type of problem generalizes several problems recently studied in the literature.
