In some statistical process monitoring applications, quality of a process or product is described by more than one ordinal factors called ordinal multivariate process. To show the relationship between these factors, an ordinal contingency table is used and modeled with ordinal log-linear model. In this paper, a new control charts based on ordinal-normal statistic is developed to monitor the ord...

Process monitoring of multivariate quality attributes is important in many industrial applications, in which rich historical data are often available thanks to modern sensing technologies. While multivariate statistical process control (SPC) has been receiving increasing attention, existing methods are often inadequate as they either cannot deliver satisfactory detection performance or cannot c...

according to the importance of positron emitters in nuclear medicine, 82mrb was produced as a member of this group of radiopharmaceuticals. after being converted into an injectable form, enough information was provided for imaging with this radiopharmaceutical. 82mrb with high radioisotopic purity and half-life of 6.5 hours, in chloride form, can be considered as a suitable positron emitter for...

MOTIVATION The process of producing microarray data involves multiple steps, some of which may suffer from technical problems and seriously damage the quality of the data. Thus, it is essential to identify those arrays with low quality. This article addresses two questions: (1) how to assess the quality of a microarray dataset using the measures provided in quality control (QC) reports; (2) how...

Control of the raw material has considerable influence on final wine quality. The objective of this work was to develop a sensor capable of assessing grape juice quality in the cellar. Sensor response was compared with conventional chemical analysis using multivariate data techniques. The aroma sensor array is composed of 14 metal oxide sensors (MOS) gas transducers plus a temperature and a rel...

This paper presents aspects related to the definition, management, and communication of data quality with application to a multivariate data set from Global Navigation Satellite System (GNSS). We stated about the quality in a context of scientific research with GNSS data presenting quality elements that can be applied to scientific research. A case study focusing on time varying quality element...

Objective: The present study aimed at examining the effectiveness of mindfulness-based cognitive therapy on psychological aspects of Quality of Life, depression, anxiety, and stress in patients with multiple sclerosis. Methods: This was a quasi-experimental research with pretest-posttest and control group design. A total of 30 members of the MS Society of Semnan City, Iran, was selected by pur...
