This paper presents a approach for noise reduction or cancellation of noise through Least Mean Square algorithm. Filtering method is used for this approach is adaptive filtering. when the signal introduced by noise it get distorted and disturbed by the noise and hence reduced audio quality. Here to overcome this problem we use this filtering technique. This technique helps to improve audio qual...

this research has studied and ranked the service quality and its relation with customers' satisfaction in a bank in iran. in the theoretical principles section, the concepts and denitions related to services, satisfaction, banking and research background have been studied. the statistical community of the study was all the bank customers that have referred to the bankand have had interest...

introduction: we can facilitate hospital management and prevent organizational crises by applying quality management principles. gharazi hospital in isfahan set up a quality management system in 1380 and in 1381 received iso 9001 , 2000 certificates. this study compared the quality management principles and the quality management system established in this hospital. methods: it is a cross-secti...

In this paper, we examine a joint lot-sizing and process investment problem with random yield and backorders. We allow for inspection and develop stochastic models which provide the optimal inspection and lot-sizing policy as well as the optimal process investment for variance reduction. The process quality loss profile around the target is captured via a modification of the Reflected Normal lo...

Developing an objective metric, which automatically quantifies perceived image quality degradation induced by blur, is highly beneficial for current digital imaging systems. In many applications, these objective metrics need to be of the noreference (NR) type, which implies that quality prediction is based on the distorted image only. Recent progress in the development of a NR blur metric is ev...

Dimensionality reduction is a big challenge in many areas. In this research we address the problem of high-dimensional hyperspectral images in which we are aiming to preserve its information quality. This paper introduces a study stability of the non parametric and unsupervised methods of projection and of bands selection used in dimensionality reduction of different noise levels determined wit...

Modified Cetyltrimethylammonium bromide (CTAB) protocol for DNA isolation was developed from leaf tissuesof Phyllanthus emblica for obtaining high quality genomic DNA. Fresh leaves of three different maturitywere analyzed for yield and quality of DNA. Acidity was determined in three different maturity of leaves viz.tender, intermediate and mature and their influence on DNA qua...
