A refugee is a person who forced to leave his or her home country due war, violence persecution and seeks safety by crossing public borders, with no intention of returning home. The number refugees has increased major crises around the world as conflict in Syria, Afghanistan South Sudan, etc. In Mohsin Hamid’s Exit West, impact explored, focus on challenges exile such language barriers, racism,...

Abstract Railway switches and crossings constitute a small fraction of linear track length but consume large proportion the railway system maintenance budget. While switch crossing (S&C) faults rarely prevent trains from running, are source many need continual attention. On rare occasions when prevented running cost disruption is very high. Condition monitoring point operating equipment tha...

The n crossing number of a graph G, denoted crn(G), is the minimum number of crossings in a drawing of G on an orientable surface of genus n. We prove that for every a > b > 0, there exists a graph G for which cr0(G) = a, cr1(G) = b, and cr2(G) = 0. This provides support for a conjecture of Archdeacon et al. and resolves a problem of Salazar.

This paper proposes a new equation to show the time domain features of jitter: Jitter = (Ti+1-Ti)/Ti. The subjects are tonal language speakers. Jitter is extracted from EGG signals. The results show that: (1) jitter does not obey Gaussian distribution but multimodal distribution; (2) the first peak position near zero of the jitter distribution curve increases with the pitch; (3) each peak posit...

We prove an analog of the Szemerédi-Trotter theorem in the plane for definable curves and points in any o-minimal structure over an arbitrary real closed field R. One new ingredient in the proof is an extension of the well known crossing number inequality for graphs to the case of embeddings in any o-minimal structure over an arbitrary real closed field.

This paper describes a methodology, and the results stemming from it, for analysing the dynamic encoding of speaker identity and dialect in prosodic parameters. A method based on employing properties of the well known Dynamic Time Warping (DTW) algorithm’s path of best match allows the separation of purely dynamic from static properties of acoustic parameters and hence their evaluation as to dy...
