Factors for teacher performance assessment for upper level students at university TecMilenio, campus ciudad Juarez

Pablo Farías (2021)

Educational evaluation is a systematic and continuous process that considers various aspects of the educational context and allows educational institutions to obtain information about student learning, the teaching-learning process, curriculum and the institution itself. TecMilenio University, like other educational institutions, seeks to address the educational needs that demand our time, through a model of learner-centered education to develop their ability to self-study, reflection and adaptation to a changing and competitive. This educational project is based on constructivist philosophy, this research demonstrates the factors involved in the evaluation process of education at the University TecMilenio by a qualitative study, and all with the aim of finding the most important biases in the ECOA survey and finally that the study can exploit a change in teacher evaluation processes in the UTM.

Un criterio integral de casualidad para procesos arma

JULIO CÉSAR CHACÓN HERNÁNDEZ (2010)

"Este trabajo trata sobre series de tiempo estacionarias en general, y procesos autorregresivos y de promedios m¶oviles (ARMA) en particular. Para una serie de tiempo estacionaria arbitraria, se estudian las propiedades de su funci¶on de autocovarianza y se analizan dos condiciones necesarias y su¯cientes para decidir si una funci¶on dada es de autocovarianza o no. Para un proceso ARMA, se desarrolla un criterio concluyente para decidir si el polinomio autorregresivo del modelo es causal. Dicho criterio involucra la integral de una funci¶on racional sobre el circulo unitario, y est¶a motivado por el teorema del residuo en la teor¶³a de funciones de variable compleja"

"This work concerns stationary time series with discrete time parameter. For a general stationary process, the properties of the corresponding autocovariance function are analyzed and two criteria for deciding if a given function is an autocovariance are studied. For the case of an ARMA process, the causality to the series with respect to the underlying white noise is studied, and a criterion is developed to decide whether or not a given polynomial is causal. Such a criterion is motivated by the residue theorem in the theory of functions of a complex variable"

Cómo incrementar la eficiencia terminal en un plantel de educación media superior

Sharo Victoria Valenzuela Izquierdo Andrea Berenice García Celestín NESTOR VALLES VILLARREAL (2021)

La eficiencia terminal permite conocer el número de alumnos que terminan un nivel educativo de manera regular. El objetivo de esta investigación es realizar un proyecto que sea útil para la evaluación de los procesos realizados en la coordinación académica del Colegio de estudios científicos y tecnológicos del estado de Tabasco plantel 7. Es importante destacar que la reprobación, el rezago y el abandono escolar son factores que impactan a la eficiencia terminal, por ende, se realiza un proyecto con la metodología FEL que sea capaz de implementar estrategias necesarias que combatan a estos factores, es muy importante identificar los contextos internos y externos de cada uno de los planteles educativos de la educación media superior, por eso cada proyecto es único dependiendo el enfoque y al plantel que va dirigido.

Deforestation processes and their negative consequences such as climatic change, soil erosion and loss of productivity and food scarcity, compromise the balance of natural systems and amplify their effect on the planet's habitability. Therefore, there is an increasing interest for developing worldwide monitoring strategies of natural areas. Since the year 1946, FAO has led a constant evaluation program of global deforestation based on information contributed by member countries; however, it has been impossible to establish a certainty level for these assessments given that each member country uses their own methodology. Recent attempts have been made for achieving a global cartography to contribute to the evaluation and monitoring of the planet's vegetated areas, but exactitude levels vary considerably. In the first part of the present work an effort is made to contribute to the validation of global land cover maps for the state of Michoacan, Mexico. To that means, five global maps and one national reference map (of the National Commission for Knowledge and Use of Biodiversity of Mexico) were compared using as criteria the surface and spatial consistencies. The comparison was first made with the original legends, later adopting a unified legend with six general classes. In the former case, inconsistencies were observed, in part due to differences in nomenclature systems and classification criteria. Using the unified legend, the overall exactitude between maps ranged from 9% to 62%. Only 2% of the pixels agree in four (mainly, urban areas and water bodies) and 88% agree in two or three of the compared maps. The main problem encountered was discrimination between croplands and natural vegetation types.

Los procesos de deforestación y los problemas derivados, como el cambio climático la erosión y la pérdida de productividad de los suelos, la escasez de alimentos, afectan el balance de los sistemas naturales y tienen una influencia más directa en la habitabilidad del planeta. De ahí el creciente interés por desarrollar estrategias de monitoreo de las superficies naturales a nivel global. Desde 1946 la FAO ha llevado a cabo evaluaciones constantes de la deforestación mundial valiéndose de la información que cada uno de los países miembros le proporciona; sin embargo, no es posible establecer un grado de certeza, ya que cada país miembro utiliza su propia metodología para reportar sus datos Recientemente se han realizado intentos de cartografía global, para contribuir a la evaluación y seguimiento de las superficies vegetales del planeta. Su exactitud a nivel local puede ser muy variable. En la primera parte del trabajo se buscó contribuir a la validación de los mapas globales para el caso particular del estado de Michoacán, México. Para ello se compararon cinco mapas globales con uno de referencia (el mapa de la Comisión Nacional para el Conocimiento y Uso de la Biodiversidad de México), tomando como criterio la consistencia de área y la espacial. La comparación se realizó primero respetando las leyendas originales y después considerando una leyenda unificada con seis clases generales. En el primer caso se observaron incoherencias, debidas en parte a las diferencias en los sistemas de nomenclatura y a los criterios de clasificación. Con la leyenda unificada, la exactitud global entre los mapas varió de 9% hasta 62%. Sólo 2% de los píxeles coincide en 4 mapas (ciudades y agua principalmente) y el 88% coincide en 2 o 3 mapas. La separación de las zonas agrícolas de otros tipos de vegetación natural fue el principal problema.

Analysis of intensified sustainable schemes for biobutanol purification

JUAN JOSE QUIROZ RAMIREZ (2020)

Butanol is an alternative fuel with characteristics competitive to petroleum-based fuels. Compared with ethanol, butanol shows less miscibility, flammability, and corrosion; while potentially replacing gasoline in car engines without modifications. However, the production cost of butanol from renewables feedstock, i.e. bio-butanol (which also contains acetone and ethanol) through fermentation remains high. This is mainly due to the low yield of butanol in fermentation. The conventional recovery of butanol by distillation is an energy-intensive

operation that has greatly restricted the industrial production of bio-butanol. This work studies ten hybrid and intensified configurations, based on the liquid-liquid extraction and dividing wall columns, to purify the butanol to the fuel grade. The study analyzes sustainability based on green metrics, including the inherent safety and control properties using singular value decomposition analysis. The results indicate that as long as the process is highly intensified, the sustainability and the inherent safety are improved and not necessarily the control properties. This is primarily due to the loss in the degrees of freedom in intensified processes.

A peak demand control algorithm for multiple controllable loads in industrial processes

JOSE LUIS MARTINEZ GODOY Fernando Martell Chávez Irma Yolanda Sánchez Chávez Francisco Antonio Castillo Velasquez Marìa del Consuelo Patricia Torres Falcòn (2021)

The peak demand or demand limit control is an important part of the actions that industries carry out to optimize their energy consumption and reduce the costs related to their electricity billing. Prioritized switching of multiple appliances is often needed in order to reduce demand and energy consumption during peak load periods. The present article describes a peak load limitation algorithm that estimates the optimal disconnection time for one or more electrical loads before the electric demand exceeds a preset limit. This algorithm uses parametric and variable load factors that vary dynamically depending on what loads are present at a given time. For its validation, a software-in-the-loop testbed was designed and developed, in which multiple electrical loads were simulated via LabVIEW software and connected to a PLC controller emulated through CODESYS software. In this environment, several test congurations were executed and evaluated to study the inuence of variables such as the nominal power and the disconnection priority of loads in the algorithm output. The results showed that the control algorithm is effective for peak load limitation, the maximum demand value reached during simulations tests did not exceed the preset demand limit at any time interval. The performance of the algorithm could be improved when prioritizing the shutdown of loads with higher nominal power or when increasing the anticipation time used for the disconnection of the controllable loads.

Dimensional analysis for tuning Selective Laser Melting parameters for near-full density of Inconel 718

ALEX ELIAS ZUÑIGA (2020)

https://orcid.org/0000-0002-5661-2802

Selective laser melting is a powder bed fusion process that allows the production of metallic pieces of high geometrical complexity. Full densification is regarded as fundamental to

achieve mechanical integrity. Nevertheless, doing so for a new material requires an intensive,

in time and resources, experimentation stage in order to set proper manufacturing parameters.

In this work, dimensional analysis is used to develop a general mathematical model on bulk

density of SLMed components taking volumetric energy density, scanning speed and powder’s thermal conductivity, specific heat capacity and average grain diameter as independent

variables. Strong relation between dependent and independent dimensionless products was

observed. Bulk density is found to be proportional to volumetric energy density and be affected by scanning speed by a factor of negative two. Inconel 718 probes were produced and

a particular expression, in the form of a first order polynomial, for its bulk density,in the independent dimensionless product π1 range from 3.17x10−8

to 4.6 x10−8 was obtained. In this

range, better densification is achieved at lower scanning speed and lower laser power. The first

is related to higher exposure time and ensuring full melt of the powder, and the second may

be due to powder particle sublimation / ejection due to improperly large laser power conditions. An average relative density of 95.218% was measured. An average error percentage of

1.6503% between experimental and predicted bulk density (and dimensionless density) was

achieved. A mathematical tool for tuning scanning speed to achieve full densification, with

respect to laser power, was developed. Moreover, particular conditions for achieving so for

Inconel 718 in the π1 range was provided.

Reactive Distillation Column Design for Tetraethoxysilane (TEOS) Production: Economic and Environmental Aspects

JUAN JOSE QUIROZ RAMIREZ (2018)

In this work, the reactive distillation (RD) is suggested to produce TEOS as an intensified technology. In general, the concept of process intensification may overcome the traditional process, since it allows design technology with reduction on equipment size, improvement in energy and mass transfer, and reduction in capital cost. Therefore, this work will approach TEOS production by means of two systems, the conventional reaction including the product separation (reaction/separation) and a reactive distillation. In order to evaluate both ways to produce TEOS, the two systems were evaluated considering the total annual cost (TAC) and return of investment (ROI) as economic indexes and the Eco-indicator 99 as an environmental index. As a result, the reactive distillation shows better performance as concern to TAC values; however, when purities above 99.5% wt are obtained, the reaction/separation system overcomes the RD as concern to ROI values. Moreover, when the environmental impact is measured, the RD showed a bigger impact near 30% in comparison with the reaction/separation system.
