ABSTRACT Purpose To validate the internal structure of Speech-Language Pathology Script Concordance Test (FonoTCS), which will be developed in a virtual, open-access format, to used assessment clinical reasoning among young professionals and students speech-language pathology with generalist background, speakers Brazilian Portuguese. Methods This is study instrument. Twenty-five specialist pathologists, more than 10 years experience, 35 summoned for Enade participated. Both groups evaluated...
In this article, we focus on multi-server queueing systems in which inter-arrival and service times are exponentially distributed (Markovian). We use a Bayesian technique, the sampling/importance resampling method (SIR), to estimate parameters of these systems, making possible determination performance measures that essential evaluation important practical applications such as computer telecommunication networks, manufacturing health care, other similar real-life problems. Extensive...
Abstract This article proposes the use of coefficient determination as a statistic for hypothesis testing in multiple linear regression based on distributions acquired by beta sampling.
In many real-life situations, certain infinite queueing systems arise in which the clients arrive according to a Poisson process and are served by single server under an approximately constant service time. An example of such system includes cycle washing machine that takes fixed length time finish one service. This represents kind this article attempts describe, estimating its traffic intensity ρ, fraction is busy can be used determine other quality measures as average queue Lq expected...
In many practical circumstances, a repair can be performed when system fails to restore condition before failure. This type of is known as minimal and one the most used models power law process (PLP). It common consider equipment failure time continuous variable in this model, assuming high degree accuracy measurement tool. However, situations, failures are usually observed recorded integer numbers units, such number days hours, indicating discrete process. study, we Weibull distribution...
This paper proposes a new control chart, denoted by X¯tn, for evaluating the stability of process mean, which is based on attribute inspection. In X¯tn mean quality characteristic interest controlled go-no-go gauge device that generates five categorizations. equally-spaced times, samples n items are collected, their categories determined, and random values generated according to truncated normal distribution corresponds categories. With these values, averages estimated charts built....
Abstract The aim of this paper is to present an online economical quality‐control procedure for attributes in a process subject quality deterioration after random shift and misclassification errors during inspections. starts control (State I) and, time, it shifts out II). Once at State II, the non‐conforming fraction increases according non‐decreasing function ψ( z ), where number items produced shift. monitoring consists inspecting single item every m items, which examined r times...
ABSTRACT In this article, we present a new control chart for monitoring the covariance matrix in bivariate process. method, n observations of two variables were considered as if they came from single variable (as sample 2n observations), and variance was calculated. This statistic used to build specifically VMIX chart. The performance compared with its main competitors: generalized sampled chart, likelihood ratio test, Nagao's probability integral transformation (v t ), recently proposed...
Abstract A number of recent research studies have applied queueing theory as an approximate modeling tool to mathematically describe industrial systems, which include manufacturing, distribution, and service, for instance. Among the main observable characteristics in queues, users system can be controlled keep waiting times minimal possible. The design efficient control charts is attempt monitor such systems. Control are proposed infinite queues with Markovian arrivals, exponential service...
Abstract A control chart for the mean of a process whose quality characteristic follows Weibull distribution is evaluated. In this sense, transformation that an exponential used involving parameters scale and form distribution. Such allows to obtain analytically limits monitor using Gamma Compared with recent results in literature, lower average run lengths after change (ARL 1 ) values are measured without need use intensive Monte Carlo simulation as well calculate ARL values. numerical...
