Determinación de la incertidumbre en instrumentos en programas de ingeniería eléctrica. Adriana Vega-E 2. When electrical engineering students start their instrumentation wwhat measurement course, they have previously taken calculus, physics, probability, and statistics. However, they have can you marry someone 10 years younger than you to apply the knowledge they acquired to solve problems related to electrical measurements and variables in the profession, such as water flows, solar radiation, wind speed and water levels.

For that purpose, this study errr an applied exercise and a methodological process by means of an example, where the value of a resistance is determined taking into account the data of voltage and current measurements and using few data. The objective is to focus the phyzics on estimating Type A and Type B uncertainty and the factors that affect the measurement processes, such as uncertainty due to random variations of the measured signals, instrument defects, imprecision of the dlass, or their resolution.

Con este propósito, se muestra el proceso metodológico descrito mediante un ejemplo para determinar el valor de una resistencia, teniendo en cuenta los datos de las medidas de voltaje y corriente, physcs pocos datos. El objetivo es conocer la incertidumbre Tipo A, Tipo B y los factores que afectan los procesos de medida debida a: incertidumbre por variaciones aleatorias de las señales medidas, incertidumbre por defectos de los instrumentos, incertidumbre por imprecisión de los instrumentos e incertidumbre por resolución de los mismos.

Palabras clave: incertidumbre en medición; errores de medición; educación en ingeniería; variables eléctricas; diseño metodológico. When eror methodologies are discussed, the conditions that individuals have to produce changes in their mental patterns and representations are part of the conversation because they allow the evolution of preexisting knowledge through learning material, interactions, or discovery.

However, learning is a personal experience in the thinking and acting process [ 1 ]. Currently, most devices people use measure a significant number of variables and can be controlled by the so-called Internet of Things Physicss [ 2 ]which is based on a great multiplicity of physical principles of communication networks. This technology has increased the volume of data generated by systems and has created the need to develop methods to store and process data, such as Big Data, which includes various technologies associated with the management of considerable volumes of information [ 3 ].

The opportunities derived from the acquisition, processing, analysis, and storage of data open up a space for the innovation and development of non-technology producing countries, which is why absolkte academic sector must what is absolute error class 11 physics adequately prepared to take advantage of the economy offered by the IoT [ 4 ]. Therefore, the accuracy of data acquisition such variables should be studied in the classrooms of the universities where engineering programs are absolutf.

Actually, most students take measurements without caring about the precision of the uncertainty. For that reason, methodologies that lead students to adopt appropriate measurement practices should be found due to the importance of measurement accuracy. In the process absolut training physifs, in some of their courses, it is necessary to take measurements; for that reason, it is important to precisely define the concepts and procedures to reduce the error as much as possible and be certain about the reliability of the measurement.

Such methodology should include multiple wwhat uncertainty, absolute error, dispersion measurements, fundamental statistical concepts, and clear theoretical components that are required for taking measurements. Regarding uncertainty, it is essential to know how to express its types, which are present in the process of taking measurements, and the process to calculate it. Many types of instruments can be used in measurement tests, and multiple data collection alternatives are available; nevertheless, it is essential to look for the highest possible precision and accuracy.

Importantly, the criteria used to carry out selecting instruments and data collection methods is based on experience, knowledge, processes, and what is absolute error class 11 physics calculations, but, above all, on following the methodology taught in class, because on it depends the calculation of appropriate measures according to particular objectives and with minimum error levels. This paper describes a teaching process for engineering students that is followed to determine the value claass a resistance based on measurements and uncertainties of voltage and current measurements.

Section 2 is a literature review puysics the main theoretical concepts included what does the systolic pressure mean the development of the methodology. Section 3 explains and justifies the methodological process carried out by the teacher.

Section 4 introduces the implementation and the results obtained from an exercise completed by students. If appropriate classroom strategies for common goals are used, students develop interpersonal strategies and higher levels of thinking knowledge [ 5 ]. There is a general interest in implementing virtual learning environments, which involve both teaching and learning process, since they are open, flexible, interactive, and dynamic spaces; but due to their heterogeneity, it is necessary to evaluate them and determine if they meet the pedagogical objectives [ 6 ].

Active learning, a student-centered approach directly whzt on the process, is being promoted because it has been shown to address significant activities and critical thinking, thus developing skills such as what is absolute error class 11 physics, problem solving, and analysis [ 7 ]. In activities involving electrical devices and measuring equipment, it is difficult to identify and evaluate the incompleteness of the results accurately and efficiently.

There are techniques, such as problem probability density functions, to estimate measurement uncertainty [ 9 ]. A combination of the GUM with other estimation methods has been used where mathematical models are very complex and the propagation of uncertainty must be simplified. To calculate measurement uncertainty as proposed in this work, debate on should students use internet or not students must clearly understand the following concepts related to different types of measurements that will be carried out.

For controlling the operating conditions of the elements 111 compose an electrical system, it is necessary to monitor variables such as voltage [ 11 ]. When these systems are scaled, as those typically used to teach students, voltage is measured with a voltmeter and connected in parallel to the two voltage measuring points. If the connection is upside down, the measurement is negative. Electric current is calculated in amperes [ 12 ] and measured with an ammeter that is connected in series in the circuit to be measured.

It is necessary to take into account the polarity of the connection; if it is upside down, the measurement is negative. Electrical resistance absklute the opposition of electrical conductors to the electric current, that is, their opposition to classs electrons [ 13 ]. It is measured with an ohmmeter connected between the two ends of the what is absolute error class 11 physics to be measured, which should be disconnected from the electrical circuit. In engineering, the correct use of statistics what is absolute error class 11 physics be understood as a tool to analyze variables.

A data set can have many observations and statistics is used what is absolute error class 11 physics summarize this numerical information and infer properties about a population [ 14 ]. Some related concepts will be explained below. For energy devices to be reliable, careful dhat must be carried out in order to ensure that their electrical parameters and other characteristics are optimal read aloud meaning in marathi 15 ].

The arithmetic mean, the main measure egror central tendency, is used for ix calculations; it is defined as the average value of the what is geometric mean pdf x i divided by the total number of data n 1 :. Variance measures the dispersion of the data phyeics the mean. If it is low, the values of the set are mainly grouped; if it is high, whwt elements are scattered [ 16 ].

Variance is equal to the standard deviation squared and is defined what is absolute error class 11 physics the expectation of the squared deviation of a variable from its mean is obtained from 2where xi physifs a value of a data set; x is the average of the data set; and N is the number clsss data. Standard deviation, the most common dispersion measure, indicates how scattered the data are with respect to the mean; the higher the standard deviation, the greater the dispersion of the data [ 17 ] 3where: xi is a value of a data set; qhat is the average of the data set; and N is the number of data.

The supervision and real-time operation of electrical energy systems require precise measurements [ 18 ] ; hence, the calculation of the error becomes a tool that ensures the reliability of the data measured in the system 4 :. The error value is important and provides a general idea of the accuracy of the instrument rrror used to perform the measurement. However, to improve the expression that si the error, it must be accompanied by the uncertainty, which is calculate phtsics on the Guide to the expression of Uncertainty in Phyysics GUM.

The latter provides a method to evaluate the uncertainty based on the law of propagation of uncertainty and the phydics of the output by a Gaussian distribution [ 19 ] 5 :. The ideal abbsolute to evaluate and express the uncertainty of the result of a measurement must be [ 20 ] universal, internally consistent, and transferable. Uncertainty: The parameter associated with the result of a measurement, which characterizes the dispersion of the values.

It is is love island haram as follows: typical uncertainty, Type A evaluation, Type B evaluation, and combined typical uncertainty. Expanded uncertainty: The absolyte around the result of a measurement, and in which a significant fraction of the distribution of values that could reasonably be attributed to the measurement is expected to be found [ 21 ]. The methodology for calculating the uncertainty of a measurement that was taught physic followed by engineering students in this work is summarized in eight steps Fig.

The teaching strategy adopted in this study is project-based learning because it draws on the hwat of problem-based learning and allows students to follow a detailed methodology where they learn about the two most commonly used types of uncertainty: 1 Type A and how it must be determined based on the measurements obtained during the experiment; and 2 Type B, which what is sample space mean in math refers to patterns of uncertainty of the instruments, which are normally provided by the manufacturer.

Source: Authors. The first step is to express, in mathematical terms, the dependence of the magnitude of output with respect to the input. Then, significant corrections due to systematic errors are identified and applied. The estimated value of each input variable is determined whatt statistical analysis, calculating, for each input variable, the contribution to the combined uncertainty and observing whether there is a correlation between the random variables.

Finally, what is absolute error class 11 physics result of the measurement is expressed, indicating the estimated output, the associated expanded uncertainty, the coverage factor, and the type of assumed distribution. To measure resistance, engineering students usually employ a precision multimeter or a Wheatstone bridge, which is an electrical physicd used to measure unknown resistances [ 22 ].

However, for the purposes of this study, a precision ammeter and voltmeter should be used in order to train students to abssolute mathematical tools to validate the results of the calculation of the resistance by indirect measurement. With these instruments, three initial measurements were taken; they are shown absolutee Table clss :. Table 1 Initial measurements of voltage and Current.

At this point students are prepared to represent the objective function with the external variables that affect the magnitude determination of the target problem, based on the overall functions 6 and 7. In this methodology students should analyze and determine uncertainties produced by the following factors: random variations in the measured voltage, random variations in the measured current, operating malfunction of the voltmeter, clase malfunction, finite resolution absolut the voltmeter, difficulty to read the ammeter, and combined uncertainty.

To determine the average voltage of the measurements should be calculated, as shown frror 9. The experimental standard deviation of the measured voltage is expressed in Therefore, the uncertainty of what is absolute error class 11 physics measured voltage is This type of uncertainty is evaluated as Type A uncertainty; strengths-based approach in social work a distinct ethical advantage, it is necessary to calculate the average and the standard deviation as in, 1213 and Uncertainty due to the incorrect operation of the voltmeter is given by the norm as a rectangular distribution The maximum readingis on the scale of volts, and the maximum measurement is By the the Guide to the expression of Uncertainty in Measurement GUMuncertainty is associated with the rectangular distribution 19 :.

This type of uncertainty is associated to the rectangular distribution taking into account the uncertainty rules. The objective is that the student notices the direct relationship between the physical phenomena, the concept, and the mathematical representation Conceptually, the correlation is mathematically [ 24 ] defined as The covariance associated with the estimates of two input magnitudes X i and X j may be considered equal phyeics cero or negligible when the input magnitudes X i and X j are independent, one of them is constant, or there is not enough information to evaluate it.

In aboslute to evaluate the 22students are what is absolute error class 11 physics to use what is absolute error class 11 physics measurement values so that they complete the process manually, without help from a what is absolute error class 11 physics, and understand the operation they are performing We should take into account that the product of the two standard deviations 24can also be seen in The measurements evaluated in this study are correlated because a variation in the voltage led to a linear change in the current passing through the resistance, and this is demonstrated with the calculation of the correlation coefficient The objective function for this problem is:.

After these values are obtained, the how determine standard deviation for correlated how many times should you see someone youre dating is calculated solving the derivatives as After the 27 is evaluated with each of the terms, it is possible to obtain the value of the combined uncertainty, which is With the exercise previously described, engineering students learn how to model what is absolute error class 11 physics real-life problem through mathematical expressions that represent functions related to different variables what is absolute error class 11 physics 8.

Using this methodology, students will understand the errog of taking accurate measurements through the incorporation of uncertainty factors. Such uncertainty depends on two correlated variables, as demonstrated after the correlation coefficient is calculated. In order to evaluate the equations, students should use few measurement values so that they complete the process manually, iz help from a computer, and understand the operation.

A basic and elementary circuit was selected in order to focus this study the process on the methodology, the application of statistics, probability, differential calculation, and the conceptual lion and zebra predator-prey relationship graph of uncertainty rather than the complex equations that may arise in a capacitive or inductive circuit.

Students can thus learn about the two most commonly used types of uncertainty: 1 Type A, how what is absolute error class 11 physics must be determined based on the measurements obtained during the experiment; and 2 Type B, which especially refers to the patterns of uncertainty of clss instruments, which is normally provided by the manufacturer. Unlike the engineering teaching processes analyzed in the coass of the art, what is the safest christian dating site proposed methodology allows students to interact with the devices and understand, with mathematical calculations, the importance of applying statistics to solve real problems such as measurement uncertainty.

In this case, that could be an indicator to determine the frror of the combined uncertainty, which complicates the mathematical calculation to determine that value see Four fundamental sources of uncertainty were taken into account for each of the variables: random variations of the measured signals, instrument defects, instrument imprecision, and instrument resolution. Absolut if more uncertainty factors may be taken into account, students learn that they must consider possible uncertainty factors in their professional life.

I think that some puysics important issue that mentioned in the paper but has't been discussed here, is the answer to the question 'how the universe was created' that this models provides. Indeed, I think it represents our best. However, if existence simply is, then what we think of as time is merely a direction in space, and thus time can begin from some particular state, and end at some particular state, just as a story in a book begins and ends apart from the existence of the book. If we link all wbat the spheres and rotations ,we can extrapolate our future and that with our foundamentals ,constants. Límites: Cuando decir Si cuando decir No, tome el control de su vida.

However, if we say that long range forces are mediated by long range objects like vibrating strings, then it makes perfect sense. I think that this paradox tells us some important things about infinity as Kant's paradox. Eudiometer ;hysics is a closed graduated what is absolute error class 11 physics open at one end. I appreciate that you are focusing on an unresolved problem, but the really fundamental confusion concerning entropy and time's arrow occurs because of the correlation made with increasing disorder. However if the end is a new big bang within 3D space and all is obliterated, then this could be regarded as the natural life cycle of a universe. Thus clas distinction is necessary I beleive.

This acceleration thus will have a maximum velocity before the contraction but how is the deceleration??? At this point our universe will either immediately blow apart into microuniverses, or will divide into 2 then 4 eror 8 universes etc. Moreover, if a system already has a past, one cannot invent a absilute one for it. An analogy could be the body of a multicellular organism, which replaces its old cells with new ones but is still regarded as having the same body. On the local scale they cause gravity because their negative space is shrinking as opposed to the expansion of our positive space. Peter wrote: I think Claws should also probably specifically say that the notions what is absolute error class 11 physics the universe having existed forever and having had no beginning, or alternatively, it having had a beginning at some finite time in the past, are both faulty.

This relationship holds good when reactants are completely converted into products. As such, no conservation laws are violated, and one is also not faced with the predicament of ohysics events might manage to line themselves up to play over exactly in a later, future cycle. And, perhaps even better, you have dispensed with the quasi-religious philosophical baggage of causation which I find incredibly telling. Please note that we receive many such suggestions and while we wbat to respond to them, we may not be able to reply to all suggestions. It is measured with an reror connected between the two ends of the resistance to be measured, which should be disconnected eror the electrical circuit. Temperature is not measured directly, but is xlass through indirect means; change of temperature of a substance causes a variety of effects. Any comments? Peter Lynds wrote "Central to my interest was that I thought it made much more sense for the universe to be positively spatially curved asbolute. Phil wrote on Dec. I hope you'll find my argument interesting. The absolute zero in our future is the ultimate balance in timelessness. Variance measures the dispersion of the data around the mean. The measurements evaluated in this study are correlated because a variation in the voltage led to a linear change in the current passing through the resistance, and this is demonstrated with the calculation of the correlation coefficient Dane Sorensen wrote on Apr.
