Abstract—Images are prone to noise induction where noise can be introduced by the medium of transfer or during image acquisition. Different filtering procedures are used for noise reduction to improve the visual quality and understandability of images. In this paper we have undertaken four types of noises and applied on a particular image. The filtering of these noises is done using four differ...

abstract   background: the x-ray machines used for radiodiagnosis should meet certain quality assurance (qa) programmes . these are necessary to have good quality radiographs at reasonably low exposure to patients.   materials and methods: dose reduction methods in abdomen x-ray examination were carried out in 10 hospitals in tehran. this paper presents the work, which was implemented on 200 pa...

BACKGROUND & OBJECTIVES The quality of life (QOL) of substance abusers is known to be severely impaired. Information on impact of opioid maintenance treatment on the QOL of opioid dependent subjects though available from the developed countries, is lacking from India. This study was carried out to assess the impact of buprenorphine maintenance treatment on the quality of life (QOL) of opioid de...

It is essential to ensure a satisfactory QoS (Quality of Service) when offering a speech communication system with a noise reduction algorithm. In this paper, we propose a new obejective test methodology for noise-reduced speech that estimates word intelligibility by using a distortion measure. Experimental results confirmed that the proposed methodology gives an accurate estimate with independ...

OBJECTIVE A total of 62,611 patients with breast hypertrophy underwent breast reduction surgery in 2013 in the United States to improve their symptoms and health-related quality of life. While multiple studies utilizing various outcome instruments demonstrate the efficacy of reductive surgery, it is presently unknown how the postoperative course affects patient satisfaction and health-related q...

bond-order conservation-morse potential (boc-mp) method is used to carry out the calculationon the co2+ h20 system. one of the best catalysts for methanol synthesis in catalytic reductionof co2 with h2o is cu/zno/a1203 whose surface is supported by with some amount of pd orga. reduction of co2 with h20 on cu will result in methanol formation; while on ni will lead tomethane formation. in the me...

one of the most important methods to produce sponge iron is coal based reduction of iron ore. direct reduction methods based on coal are being improved due to the abundance of coal sources and its lower cost in comparison with natural gas. volatile materials in coal play an important role in the reduction of iron oxides. in this study, noncoking coal with high volatile materials from iran and c...

background: health assessment in patients  with epilepsy (pwe) should  include  both  clinical outcomes and  health related quality of life (hrqol) measures. the quality of life (qol) in epilepsy-31 inventory  (qolie-31) is widely used for qol studies  in epilepsy. this study  aims to evaluate psychometrics  of the persian version of the inventory (qolie-31-p). methods:  following a  standard  ...
