introduction: few researches have been conducted researches on the influence of the type of dental stone used for fabrication of casts on the adaptation of denture bases. the purpose of this study was to compare the effect of two types of stone casts on the accuracy of fit in complete denture bases. methods: using sixty fully replicated master casts obtained by duplicating a metal die represent...

As a widely used proliferative marker, Ki67 has important impacts on cancer prognosis, especially for breast cancer (BC). However, variations in analytical practice make it difficult for pathologists to manually measure Ki67 index. This study is to establish quantum dots (QDs)-based double imaging of nuclear Ki67 as red signal by QDs-655, cytoplasmic cytokeratin (CK) as yellow signal by QDs-585...

This paper describes how a Many Faceted Rasch Measurement (MFRM) approach can be applied to performance assessment focusing on rater analysis. The article provides an introduction to MFRM, a description of MFRM analysis procedures, and an example to illustrate how to examine the effects of various sources of variability on test takers’ performance on a writing test by means of a MFRM analysis. ...

Present power systems operate in more and more difficult conditions generated by various physical and economic factors. Pushing the power system closer to its physical limits worsens the reliability and security of the general operating conditions. Hence, a better control across the entire grid, through more intensive online analysis is needed. At present, a common point of view considers that ...

The objective of this study was to assess the precision and accuracy of a nonproprietary, optical three-dimensional (3D) motion analysis system for the simultaneous measurement of soft tissue strains and joint kinematics. The system consisted of two high-resolution digital cameras and software for calculating the 3D coordinates of contrast markers. System precision was assessed by examining the...

In this paper, the modeling for a complete scenario of a proposed wide area measurement system (WAMS) based on synchronized phasor measurement units (PMUs) technology with the access of a broadband communication capability is presented. The purpose is to increase the overall system efficiency and reliability for all power stages via significant dependence on WAMS as distributed intelligence age...
