Este documento analiza diferentes estadísticos basados en los residuos para la hipótesis nula de no cointegración utilizando MCG para eliminar los componentes determinísticos. Las distribuciones asintóticas son simuladas para los casos donde un intercepto y un intercepto y una tendencia son incluidos en la ecuación de cointegración. Los resultados muestran que las distribuciones asintóticas dependen del número de regresores (variables xt), el número y clase de componentes determinísticos y un parámtro de nuisamce R2 que mide la correlación de largo plazo entre los regresores xt y la variable yt. Los resultados muestran que MCG permiten obtener más potencia que el uso de MCO. Esto es más claro para valores de R2 menores que 0:4 y un solo regresor xt. Para valores mayores de R2 los denominados estadísticos ECR son mejores para cualquier número de regresores. En particular ...

This paper involves a practical approach to perform quality-control/quality-assessment of concrete using vibration-based NDT. The first component is the analysis of compressive strength and dynamic E-modulus of concrete samples from various construction projects. The second component involves continuous measurements of E-Moduli as a function of curing time in laboratory-controlled specimens. The experimental program allowed proposing a correlation to predict the expected static and dynamic E-modulus at 28 days from their measurement at any instant of the curing process. A similar relationship is proposed to predict compressive strength at 28 days based on the dynamic E-modulus measured at earlier ages.

Particle physics emerged as a pioneer discipline in "big science"; experiments are being carried out in accelerators that are increasing in energy and complexity by the collaborations of thousands of physicists from hundreds of institutes in a few dozen countries. In "big science" a research methodology has been developed in which statistics is of great importance to interpret the results obtained from these experiments. Despite the discovery of the Higgs boson in 2012, which contributed to the success of the Standard Model and the award of the 2013 Nobel Prize in Physics. Based on these motivations, in the present work certain statistical tests based on the “likelihood” method are shown and are applied in high energy physics in the discovery of new phenomena, by making use of the construction of confidence intervals of the model parameters. We focus on properties of methods called ...

In the competition of the lighting market, LED technology has stood out for excellent characteristics, one of which is the possibility of dimming, compared to other technologies. The dimming capacity allows to find the comfort zone with respect to two parameters, illuminance and correlated colour temperature (CCT). The present work provides a methodology to find comfort with respect to two variables, the level of illumination and the CCT. A controller with a simple structure, supported by Arduino, is proposed to control the above-mentioned variables of LEDs. The LEDs are located on a tape attached to a heat sink. In addition, the use of a light box as an environment for analysis is proposed. The design of this cubicle is based on literature. The controller has the possibility to regulate 12 different channels and the linearity between the PWM output and the illuminance was verified. The ...

One of the problems in the care of coronary patients is accurately assessing the functional state of the myocardium. Contributions from Master ( 25, 26) , using the Test of electrocardiographic Effort constitute itself a doctrinal issue in evaluating the state of coronary sufficiency. However, results based seudonegativos Scherf and Schaffer ( 33 ) can be found in 20% , and even the same Master considered by over 50 % . Recent research by Simonson (34, 35, 36 ), reviews the impact should be taken into account also in seudopositivos results. Be remembered that if a Stress Test is negative , is no guarantee for exempting imminent post coronary insufficiency ( 12). With the introduction of Practice Ballistocardiography by Dock system (10 ) , ( 11) , it is possible to insist on this method to find out the exact behavior of the myocardium in patients with coronary disease.

Purpose: The technical feasibility of using Benford's law to assist internal auditors in reviewing the integrity of high-volume data sets is analysed. This study explores whether Benford's distribution applies to the set of numbers represented by the quantity of records (size) that comprise the different tables that make up a state-owned enterprise's (SOE) enterprise resource planning (ERP) relational database. The use of Benford's law streamlines the search for possible abnormalities within the ERP system's data set, increasing the ability of the internal audit functions (IAFs) to detect anomalies within the database. In the SOEs of emerging economies, where groups compete for power and resources, internal auditors are better off employing analytical tests to discharge their duties without getting involved in power struggles. Design/methodology/approach: Records of eight databases of an...

We present a simple test of spatial autocorrelation based on the skedastic structure of the spatial series. Its distribution function is known for all sample sizes. Moreover, it is very simple to obtain, specially in a case of small samples where the new GQsp test has great power, higher than other alternatives existing in the literature.

The application of different unit root statistics is by now a standard practice in empirical work. Even when it is a practical issue, these statistics have complex nonstandard distributions depending on functionals of certain stochastic processes, and their derivations represent a barrier even for many theoretical econometricians. These derivations are based on rigorous and fundamental statistical tools which are not (very) well known by standard econometricians. This paper aims to fill this gap by explaining in a simple way one of these fundamental tools: namely, the Functional Central Limit Theorem. To this end, this paper analyzes the foundations and applicability of two versions of the Functional Central Limit Theorem within the framework of a unit root with a structural break. Initial attention is focused on the probabilistic structure of the time series to be considered. Thereafter...

Bacterial cellulose has a variety of applications both in the paper, textile, food, cosmetic and medicine industries; This is due to its excellent physicochemical properties such as: high degree of purity, high crystallinity, excellent biodegradability, high Young's modulus, high water retention capacity and excellent biological affinity. The objective of this work was to evaluate cellulose production by bacteria isolated from sugarcane. The collected samples were allowed to ferment until the appearance of a thick film on the surface, from which axenic cultures were obtained on the HS medium. Isolated cultures were transferred to HS brothand incubated under static conditions until a film formed on the culture surface. Bacterial identification was carried out based on a physiological characterization of the isolated strains and their capacity to produce cellulose. FT-IR analysis of the fi...

Mycobacterium tuberculosis causes one of the diseases with the highest mortality and morbidity rate in the Americas and around the world. In developing countries, the diagnosis of tuberculosis (TB) is based on smear microscopy and bacteriological cultures. The first method has low sensitivity, and the second take several weeks to reach a confirmatory diagnosis. The lack of a rapid diagnosis compromises the efforts to control TB, favoring its transmission to the susceptible population. Currently, magnetic nanoparticles (MNPs) functionalized with biomolecules have been used in biomedicine, due the magnetic, electrical and optical properties. In this way, applying external magnetic fields, biofunctionalized MNPs are used to detect and concentrate cells and biomolecules from biological samples. In this work we present the synthesis, characterization and bio-functionalization of magnetic nano...
