Noise is an important factor that degrades the quality of medical images. Impulse noise is a common noise, which is caused by malfunctioning of sensor elements or errors in the transmission of images. In medical images due to presence of white foreground and black background, many pixels have intensities similar to impulse noise and distinction between noisy and regular pixels is difficult. In ...

introduction: traumatic eye injuries (tei) involved about 3% of cases referred to the emergency departments of developing countries. lens dislocation is one of the critical cases of ophthalmic emergencies. the present study was aimed to evaluate the diagnostic accuracy of ultrasonography in detection of traumatic lens dislocation. methods: in this cross-sectional study the findings of ultrasono...

introduction: the correlation of central venous pressure (cvp) with inferior vena cava (ivc) sonographic diameter has been reported in several studies. however, few studies have attempted to find the best anatomic location of measurement. therefore, the purpose of this study was determining the best anatomic location to find precise correlation between cvp and ivc diameter using transesophageal...

The Generalized Lambda Distribution is a popular tool for generating random numbers following a wide range of non-normal, asymmetric distributions. In this short paper we assess the accuracy of the technique in replicating moments across a range of “sample sizes.” We find that accuracy is highly dependent on sample size, particularly with respect to the third and fourth moments. Generally, acce...

We present an evaluation of our protein-protein docking approach using the ZDOCK and ZRANK algorithms, in combination with structural clustering and filtering, utilizing biological data in Rounds 6-11 of the CAPRI docking experiment. We achieved at least one prediction of acceptable accuracy for five of six targets submitted. In addition, two targets resulted in medium-accuracy predictions. In ...

Localization, an important challenge in wireless sensor networks, is the process of sensor nodes self-determining their position. The difficulty encountered is in cost-effectively providing acceptable accuracy in localization. The potential for the deployment of high density networks in the near future makes scalability a critical issue in localization. In this paper we propose Cluster-based Lo...

Background: The accuracy of reduction of ankle fractures using postoperative plain radiographies (x-ray) remainswidely controversial. Some authors have demonstrated that postoperative computed tomography (CT) scan can beuseful for these patients. In current study, the efficacy of x-rays after fixation of ankle fractures was investigated basedon the CT scan findings.Metho...
