The range of Inverse Kinematics has been extended by integrating the mass distribution information to embody the control of the position of the center of gravity of any articulated figure in single support (open tree structure). The underlying control architecture of main and secondary behaviors (or tasks) is used to associate the position control of the center of gravity with other behaviors. ...

This study investigates spectral characteristics of the release bursts in Korean alveolar stops in terms of intensity, center of gravity, and skewness of the spectra of the release burst across phonation types and speakers. The results showed that there was no significant difference in intensity, center of gravity, or skewness across phonation types but a significant difference across speakers....

The present study considered a fuzzy natural color system (NCS) in which triangular pyramid membership functions are constructed on the NCS color triangle. This system can process a fuzzy input to an NCS system and output to a center of gravity of three weights associated with respective grades. Triangular membership functions are applied to the hue, and triangular pyramid membership functions ...

Estimating the gravity anomaly causative bodies boundary can facilitate the gravity field interpretation. In this paper, 2D discrete wavelet transform (DWT) is employed as a method to delineate the boundary of the gravity anomaly sources. Hence, the GRACE’ satellite gravity data is decomposed using DWT. DWT decomposites a single approximation coefficients into four distinct components: the appr...

We study stability of underwater vehicle dynamics for a six-degree-of-freedom vehicle modeled as a neutrally buoyant, submerged rigid body in an ideal fluid. We consider the case in which the center of gravity and the center of buoyancy of the vehicle are noncoincident such that gravity introduces an orientation-dependent moment. Noting that Kirchhoff’s equations of motion for a submerged rigid...

ranking fuzzy numbers plays a very important role in decision making and some other fuzzy application systems. many different methods have been proposed to deal with ranking fuzzy numbers. constructing ranking indexes based on the centroid of fuzzy numbers is an important case. but some weaknesses are found in these indexes. the purpose of this paper is to give a new ranking index to rank vario...

Abstract Atmospheric gravity waves (AGWs) are low-frequency, buoyancy-driven that generated by turbulent convection and propagate obliquely throughout the solar atmosphere. Their proposed energy contribution to lower atmosphere sensitivity atmospheric parameters (e.g., magnetic fields radiative damping) highlight their diagnostic potential. We investigate AGWs near a quiet-Sun disk center regio...

Modified Newtonian dynamics, a successful alternative to the cosmic dark matter model, proposes that gravitational field deviates from the Newtonian law when the field strength g is weaker than a critical value g0. We will show that the dynamics of MOND can be derived from an induced gravity model. New dynamics is shown to be compatible with the spatial deformation of scalar fields coupled to t...

Detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. This distribution could be detected by different geophysical methods, especially gravity method. However, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. Performance of the gravity technique co...
