Existing discussions of polysemy describe the relations that extended senses may have to the most central sense of a word, but they do not explain in more detail how particular senses are generated for a given word. We propose that extended senses are initially built on the salient features of referents of core senses (and further senses may be generated from those). We provide evidence for the...

In this paper color image segmentation is accomplished using MRF model. The problem is formulated as a pixel labeling and the true labels are modeled as the MRF model. The observed color image is assumed to be the degraded version of the true labels. We assume the degradation to be Gaussian distribution. The label estimates are obtained by using Bayesian framework and MAP criterion. The (I1, I2...

The three invariants of C are key to expressing this tensor and its inverse as a polynomial in C. Simple and symmetric expressions are presented connecting the two sets of invariants {I1, I2, I3} and {i1, i2, i3} of C and C, respectively. The first result is a bivariate function relating I1, I2 to i1, i2. The functional form of i1 is the same as that of i2 when the roles of the C-invariants are...

The heat transfer characteristics of the working fluid passing through absorber a solar parabolic trough collector (SPTC) can be enhanced by creation turbulence effect. Therefore, novel idea was implemented introducing corrugated tube (CT) instead plain in collector. enhancement improved further use conical strip inserts inside SPTC. A receiver with pitch 8 mm and corrugation height 2 used thre...

We prove that almost all digraphs not embedding an independent set of size 3 consist of two disjoint tournaments, and discuss connections with the theory of homogeneous simple structures. Our main result can be stated informally as saying that almost all finite directed graphs in which any three vertices span at least one directed edge consist of two tournaments with some directed edges between...

The current sanitary crisis due to COVID-19 has further evidenced the enormous digital exclusion of older adults. Furthermore, urged adults adopt new technologies facilitate their tasks, as well provide them with an effective means against loneliness and social isolation caused by confinement. In light this, Digital Literacy is necessary for all those excluded from era, who are characterized ma...
