1. Economic design of a nonparametric EWMA control chart for location
Abstract In this article, we have proposed an economic design of Exponentially Weighted Moving Average control chart based on sign statistic to control location parameter of the process. The economic performance of the chart is evaluated for different shifts in the location. It is observed that, as shift in the process location increases, sample size to dete

2. The low-level laser on acute myositis in rats
ABSTRACT PURPOSE: To analyze the effects of the low-level laser therapy in the acute myositis induced in rats. METHODS: Twelve rats were subjected to bilateral ovariectomy for inducing osteoporosis. After surgery, they were divided into two groups: Ovariectomy-control group (G1, n=6), receiving 0.5 ml distilled water by gavage for 30 days, and Ovariectomy

3. Steady-state behavior of nonparametric control charts using sign statistic
Abstract If process is running for a long period in an in-control condition, it will reach in a steady-state condition. In order to study the long term properties of a control chart, it is appropriate to investigate the steady-state average time to signal. In this article, we discussed runs rules representation of a nonparametric synthetic control chart usin

4. Análise de genes diferencialmente expressos nas vias de sinalização (Hedgehog e Wnt) em carcinomas basocelulares humanos
Hedgehog (HH) and Wingless-Int (Wnt) signaling pathway are related to the process of cellular proliferation, differentiation, angiogenesis, matrix remodeling and homeostasis of stem cells. Over the years, several mutations in HH signaling pathway have been identified, including the loss of function mutations in ptch1 and the gain of function mutations in smo

5. Uma ánalise do procedimento de controle on-line de qualidade de Taguchi baseado nos resultados de uma sequência de inspeções
In this paper, a procedure for the on-line process control of variables is proposed. This procedure consists of inspecting the m-th item from every m produced items and deciding, at each inspection, whether the process is out-of-control. Two sets of limits, warning ( bW 0 Ý ) and control ( bC 0 Ý ), are used. If the value of the monitored statistic falls b

6. An analysis of Taguchi's on-line quality monitoring procedure for variables based on the results of a sequence of inspections
In this paper, a procedure for the on-line process control of variables is proposed. This procedure consists of inspecting the m-th item from every m produced items and deciding, at each inspection, whether the process is out-of-control. Two sets of limits, warning (µ0 ± W) and control (µ0 ± C), are used. If the value of the monitored statistic falls bey

7. AVALIAÇÃO DO PROCESSO DE ENRIQUECIMENTO DE FARINHA DE TRIGO COM APOIO DO CONTROLE DE PROCESSOS / EVALUATION OF THE ENRICHMENT OF WHEAT FLOUR WITH THE SUPPORT OF PROCESS CONTROL
As políticas governamentais em saúde estão direcionadas para as medidas preventivas. Neste sentido, foi estabelecido em 2002 pelo governo federal brasileiro, e já em execução em vários países, que fossem enriquecidas com ácido fólico e ferro as farinhas de trigo e milho. O objetivo desta pesquisa foi avaliar o processo de enriquecimento de farinha

8. Estratégias de aprendizagem e de regulação emocional de estudantes dos cursos de formação de professores / Learning and emotional regulation strategies in training courses students
Learning and emotional regulation strategies are important for academic self-regulation, because they give to the student an opportunity be conscious and to control their thinking and their emotional state. The theorethical reference to this search was Cognitive Psychology based on the Theory of Information Processing and the aim was to describe learning and

9. Avaliação dos procedimentos higiênico-sanitários utilizados durante a coleta domiciliar e o transporte do leite humano ordenhado / Assessment of the hygienic-sanitary procedures used during collection and transportation of household human milk
The breastfeeding is considered one of the main strategies for child survival and the Human Milk (HM) is the ideal food for the term newborn and pre-term newborn, with the capabilities to supply essential nutrients for their development. In the absence or insufficient volumes of milk from their mother, especially for hospitalized children as newborns pre-ter

10. Application of herbicides to floating rate using predictive control / Aplicação de herbicidas a taxas variáveis utilizando controle preditivo
The objective of this project is to study a predictive controller for a herbicides injection system with variable rates where the herbicide and water are placed in different recipients and sent to a mixer. A strategy to generate the reference for the predictive controller characterizes the system as hybrid because there are two modes of operation for the her

DETERMINATION OF THE UNCERTAINTY OF MEASUREMENTS FOR API STEEL PLANT SAMPLE / Validação de métodos para as técnicas de WDXRF e OES -spark, na análise de aços. Cálculo de incerteza de medição para amostras de processo, aço classe API
The increase of gas and petroleum demanding in the national and international markets, the specification and certification of the chemical analysis results of gas and oil pipe-line have became more and more challenging. A continuous development has been outlined to improve API grade alloy steels (American Petroleum Institute). The steel properties depend on
