Introduction: It has long been recognized that the Gaussian diffusion tensor model is inappropriate for voxels with complex fiber architecture [1, 2]. Many groups have tried to classify voxels in terms of their diffusion complexity. The earliest studies distinguished between voxels with isotropic, single-fiber anisotropic, and multifiber anisotropic complexity and have reported clustered and sy...

Sentiment analysis of weblogs is a challenging problem. Most previous work utilized semantic orientations of words or phrases to classify sentiments of weblogs. The problem with this approach is that semantic orientations of words or phrases are investigated without considering the domain of weblogs. Weblogs contain the author’s various opinions about multifaceted topics. Therefore, we have to ...

Free vibration characteristics of continuous grading fiber orientation (CGFO) beams resting on variable Winkler and two-parameter elastic foundations have been studied. The beam is under different boundary conditions and assumed to have arbitrary variations of fiber orientation in the thickness direction. The governing differential equations for beam vibration are being solved using Generalized...

Fundamental understanding of the goaf gas distribution in a gassy coal mine is necessary for developing effective goaf gas drainage strategies in the longwall coal mine. The goaf gas was subjected to the surface and body forces that were classified depending upon whether they acted on the surface area or the volume of the gas element. Of these forces, the body forces were more predominant in di...

It is often held that the self-employed are an economically conservative, political right-wing class. Previous studies, however, have primarily dealt with self-employed workers as a relatively monolithic social class with shared interests as entrepreneurs and (potential) employers. But, with its recent rise, self-employment has developed into a heterogeneous employment type, with a growing numb...
