XBAR resonators in 128° Y-cut Lithium Niobate LiNbO3 [PDF]
The increasing demand of higher frequencies technologies in RF (Radio frequency) components, especially for telecommunication, create a need to develop wider and higher frequency bands filters, with optimal performances. Thus, constant effort are made to

Variable Control Charts using a Type-2 Interval Fuzzy Approach
, 2023 Os gráficos de controle são uma das ferramentas da qualidade mais importantes dentro do CEP (Controle Estatístico de Processos) e são utilizados no monitoramento de variáveis de processo que podem ser entendidas como características de qualidade.

A robust Xbar control chart [PDF]
, 2013 This article studies alternative standard deviation estimators that serve as a basis to determine the control chart limits used for real-time process monitoring (phase II). Several existing (robust) estimation methods are considered.

Optimal design of the double sampling X chart based on median run length
, 2012 The double sampling (DS) Xbar chart is effective in detecting small to moderate process mean shifts and reducing the sample size. The average run length (ARL) is an intuitively appealing and widely used optimization criterion in the designof a control ...

Design of the synthetic-X control chart
, 2012 The Xbar chart is widely used to monitor the mean of a quality characteristic xbar. This chart decides the process status based on the magnitude of the sample mean xbar and is effective for detecting large mean shifts.

A Unifying Concept of X Chart and X-Bar Chart when Subgroup Sizes are Equal
Journal of Mathematical and Fundamental Sciences, 2019 X chart and X-bar chart are usually seen as two techniques in SPC with different concepts. In this paper we propose two propositions as a unifying concept for those two charts; one for start-up stage and the other for process control for future ...

, 2000 Consider the random sampling of a discrete population. The observations, as they are collected one by one, are enhanced in that the probability mass associated with each observation is also observed. The goal is to estimate the population mean.
