Most control charts for variables data are constructed upon the assumption that the observations from a process are independent. In most applications however this assumption does not hold. The performance of process control schemes have to be evaluated in such circumstances. However most of the work published deal with shifts in the location of correlated processes. In this paper, the ARL perfo...

Resumen. Debido a la gran popularidad que han adquirido actualmente las redes sociales entre personas, empresas, figuras públicas etc., surge la necesidad de contar con métodos automáticos que faciliten la búsqueda, recuperación y análisis de grandes cantidades de información. Ante esto, el Analista de Reputación en Ĺınea (ARL) enfrenta el reto de identificar temas relevantes alrededor de un ev...

ADP-ribosylation factor-like (ARL) proteins are small GTPases that undergo conformational changes upon nucleotide binding, and which regulate the affinity of ARLs for binding other proteins, lipids or membranes. There is a paucity of structural data on this family of proteins in the Kinetoplastida, despite studies implicating them in key events related to vesicular transport and regulation of m...

This study investigates the statistical process control application for monitoring queue length data in M/G/1 systems. Specifically, we studied the average run length (ARL) characteristics of two different control charts for detecting changes in system utilization. First, the nL chart monitors the sums of successive queue length samples by subgrouping individual observations with sample size n....

This paper introduces adaptive reinforcement learning (ARL) as the basis for a fully automated trading system application. The system is designed to trade FX markets and relies on a layered structure consisting of a machine learning algorithm, a risk management overlay and a dynamic utility optimization layer. An existing machine-learning method called recurrent reinforcement learning (RRL) was...

At the end of the twentieth century, the year 2000 (Y2K) date change problem threatened computers and digital systems around the world. Y2K refers to computer and automated control system malfunctions that could have occurred when the year changed from 1999 to 2000. Many computers and automated systems were engineered to handle only two-digit year formats, and would have made mistakes or stoppe...

The effects of three dissolving agents on the accuracy of an electronic apex locator- (EAL-) integrated endodontic handpiece during retreatment procedures were evaluated. The true lengths (TLs) of 56 extracted incisor teeth were determined visually. Twenty teeth were filled with gutta-percha and a resin-based sealer (group A), 20 with gutta-percha and a zinc oxide/eugenol-based sealer (group B)...
