background: we aimed to analyze the effect of nursing strategies on patients with chronic renal failure (crf) undergoing maintenance hemodialysis (mhd) treatment by puncturing on arteriovenous fistula (avf). methods: ninety-two patients with chronic renal failure undergoing maintenance hemodialysis (mhd) between jan 2014 and jan 2015 were included in the study (all undergoing avf, dialysis for ...

In this paper introduce the average outgoing quality (AOQ) and average total inspect (ATI) for single sampling plan when that proportion nonconforming items is fuzzy number. We have shown that AOQ and ATI curves of the plan are like a band having a high and low bounds. Keywords—Statistical quality control, acceptance single sampling, average outgoing quality, average total inspection, fuzzy num...

⎯ Quality control in ceramic tile manufacturing is hard, labor intensive and it is performed in a harsh industrial environment with noise, extreme temperature and humidity. It can be divided into color analysis, dimension verification, and surface defect detection, which is the main purpose of our work. Defects detection is still based on the judgment of human operators while most of the other ...

Although the 802.11e extension of the IEEE 802.11 standard for wireless local area network was concerned to provide Quality of Service, such provisioning cannot be achieved without specific traffic control mechanisms. In this paper, the use of admission control based on measurement for QoS provision in 802.11e networks is evaluated. It is shown that QoS differentiation can be obtained with the ...

Introduction: The evaluation of X-ray and light field coincidence in linear accelerators as a quality control test is often performed subjectively, involving the manual marking of films and their visual inspection following the irradiation. Therefore, the present study aimed to develop an objective method for the performance of this test leading to the increased levels...

background: quality assurance in the hematology laboratory is a must to ensure laboratory users of reliable test results with high degree of precision and accuracy. even after so many advances in hematology laboratory practice, pre-analytical errors remain a challenge for practicing pathologists. this study was undertaken with an objective to evaluate the types and frequency of preanalytical er...
