With the increase in coverage area of magnetotelluric data, three-dimensional modeling spherical coordinates and its differences with respect to traditional Cartesian have gradually attracted attention. To fully understand influence Earth’s curvature map projection deformations on modeling, qualitative quantitative analyses based realistic models need be examined. Combined five representative p...

Music emotion plays an important role in music retrieval, mood detection and other music-related applications. Many issues for music emotion recognition have been addressed by different disciplines such as physiology, psychology, cognitive science and musicology. We present a support vector regression (SVR) based music emotion recognition system. The recognition process consists of three steps:...

Wavefields are commonly computed in the Cartesian coordinate frame. Its efficiency is inherently limited due to spatial oversampling in deep layers, where the velocity is high and wavelengths are long. To alleviate this computational waste due to uneven wavelength sampling, we convert the vertical axis of the conventional domain from depth to vertical time or pseudo depth. This creates a nonort...

As a tool for understanding the meridional circulation of the atmosphere, a two-dimensional ( latitude – height ) numerical model is used to clarify the relationship between the Hadley circulation and large-scale motions associated with moist convection. The model is based on the primitive equations including the moist process, and two kinds of coordinates are used: the spherical coordinate and...

In this paper three-dimensional heat conduction equation in cartesian coordinate has been solved two different methods one of which depends on the separation variables and other integral transform .The results are got plotted by using Matlab. And obtained showed difference between that were used solution . That is evident illustrations According to it was concluded method best because fewer ste...

BACKGROUND Before extracting impacted lower third molars, dentists must first identify the spatial relationship between the inferior alveolar nerve (IAN) and an impacted lower third molar to prevent nerve injury from the extraction. Nevertheless, the current method for describing the spatial relationship between the IAN and an impacted lower third molar is deficient. Therefore, the objectives o...

Abstract Despite the continuous development of hardware, most construction machines are exclusively teleoperated limiting control to a single paradigm. The operators usually have move different joints machine in coordinated way solely relied on their experiences leading reduced local accuracy and work efficiency. Automation machinery can open up new possibilities improve efficiency safety durin...

In this paper, we propose a novel method for face recognition which uses the polar coordinate system instead of the conventional cartesian coordinate system. Among the central area of a face, we select a point as a pole and make a polar image of a face by evenly sampling pixels in each direction of 360 degrees around the pole. The polar coordinate system delineates near-pole area more vividly t...
