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...

in 1955, the first nuclear medicine division was established in thailand by professor romsai suwannik in the department of radiology, siriraj hospil, mahidol university in bangkok. in 1959 four years later, the second nuclear medicine division was established in the department of radiology, chulalongkorn hospital in bangkok. the third nuclear medicine division was started in rajvithi hospital i...

BACKGROUND Harmful alcohol use has been linked to the spread of HIV in Kenya. It also adversely affects those on antiretroviral (ARV) treatment through poor compliance. This study using participatory research and action (PRA) methods sought to understand factors related to alcohol abuse and non-adherence and to formulate appropriate interventions in a sample of people living with HIV and AIDS (...

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...

in this work the performance of a wavelength division multiple access (wdma) system with direct detection receiver is investigated. for this purpose, the probability of error in a wdma network with ook modulation considering crosstalk, isi, photo detector noise and thermal noise is calculated and the effect of each on system performance is investigated. the system performance in presence of pin...
