The speech enhancement techniques are often employed to improve the quality and intelligibility of the noisy speech signals. This paper discusses a novel technique for speech enhancement which is based on Singular Value Decomposition. This implementation utilizes a Genetic Algorithm based optimization method for reducing the effects of environmental noises from the singular vectors as well as t...

symmetric division deg index is one of the 148 discrete adriatic indices that showed good predictive properties on the testing sets provided by international academy of mathematical chemistry.symmetric division deg index is defined by$$sdd(g) = sume left( frac{min{d_u,d_v}}{max{d_u,d_v}} + frac{max{d_u,d_v}}{min{d_u,d_v}} right),$$where $d_i$ is the degree of vertex $i$ in graph $g$.in this pap...

objective:in this study, we assess long-term effects of vertical dome division (v.d.d) and suture techniques in patients with bulbous nose deformity and then compare the efficiency of these methods. material and methods: in this study 70 patients with bulbous nose deformity were divided into two equal groups of a and b in which group a with suture (transdomal and interdomal) technique and grou...
