Comparative analysis of the conversion performance of a grid-connected
photovoltaic system
Authors: Bueno-Rivera Raymundo
Published: April 2024

A performance study of a photovoltaic system installed in
an eco-house on the campus of the University of Calgary
in Canada is presented. The panels of the photovoltaic
array installed on the roof have different azimuth and tilt
angles, therefore, the solar energy incident on them is
different. The effects of orientation on the efficiency of
electrical energy production in individual photovoltaic
modules are analyzed. The conversion efficiency is
determined by means of measurements of the energy
produced by the modules, supported by the RETScreen
software, but also independently, it is calculated using the
radiation data from the university weather station (WRS).
These results are compared with those of a previous study,
carried out with PVSyst, where the orientation angles of
the system are simplified. Average results of energy
produced, and efficiency are shown. It is observed that the
efficiencies from the simulations are very similar,
although of lower value. The results obtained with WRS
are considered more realistic and of greater magnitude.
Energy and exergy analysis at the la joya sugar mill in Champotón,
Campeche, Mexico
Authors: Chan-Gonzalez Jorge J.
Published: April 2024

An energy and exergistic analysis was carried out on the
bagacera boiler of the sugar mill "La Joya" located in
Champotón, Campeche, making the following assumptions: the
process develops in a permanent state, the mass that flows
through the control volume does not suffer variations with
respect to time, there are no work interactions of the system with
the environment, changes in kinetic energy and potential energy
are considered negligible, thermodynamic data were provided by
the mill's operation and control center. It was found that by
increasing the mass flow of feed water (mwater) and decreasing
the temperature of the dead state (T0) there was the least
destruction of exergy. Simulations were carried out to determine
the energy and exegetical efficiencies of the mill as a whole with
the help of the Software Engineering Equation Solver (EES).
When modifying m ̇_water, with T0 at 25 ℃, and inlet water
(Twater) 90 ℃, an increase was observed both efficiencies; the
energetic reached a maximum of 88, and the exergetic of 31; It
was also observed that the maximum energy efficiency is
obtained with the Twater 45℃. On the contrary, the exergetic
efficiency at 15.3. It was concluded that it is more important to
increase the mass flow of inlet water to increase global
efficiencies in mill facilities than its temperature.

Study of psychosocial risk factors in companies in Cd. Obregón, Son. Mexico
Authors: Naranjo-Flores Arnulfo Aurelio
Published: April 2024

The study of organizational and psychosocial aspects and
their relationship with occupational health is not new,
although it has acquired importance and recognition in
recent years (Houdmont and Leka 2010; Näswall,
Hellgren, Sverke, 2008). The objective of the study was to
determine the level of exposure to severe traumatic events
and psychosocial risks in local workers. The methodology
is based on (Herrara, Medina, & Naranjo, 2010) and the
Prevention Technical Note 702 (INSST, 2005). As a
result, it was obtained that medium-sized companies
present a low risk level with 43.48% and 39.13% medium
risk, on the other hand, large-sized companies obtained
mostly low risk with 30.51% and medium risk with
25.42%. Of the people surveyed, 14.29% present severe
traumatic factors and require clinical evaluation (8.99%
men and 5.29% women). The conclusion of the study is
that the size of the company does not have a direct
influence and that the factors with the greatest influence
and highest level of risk in both cases are related to the
workload and the organization of time to carry out the
work.

NOM-037-STPS-2023 as a mixed work alternative for HEIs (Case of the Academic Unit of Accounting and Administration of the Universidad Autónoma de Nayarit
Authors: Navarrete-Méndez Adrián
Published: April 2024

The following research paper aims to investigate the partial
implementation of teleworking for the teachers in the
Department of Accounting and Administration in accordance
with NOM-037-STPS to offer an alternative solution for the lack
of installed resources (furniture, equipment, and internet
network). The situation of the Department of Accounting and
Administration is no exception. On one hand, the institution
demands an 8-hour workday and strict compliance with
academic performance indicators; however, the institution does
not have the necessary academic spaces to carry out these tasks.
The total number of cubicles is insufficient to accommodate all
the teaching staff in the morning, afternoon, and for semi-school
shifts. In addition to the fact that these cubicles do not have
computer equipment, very few have appropriate furniture, and
the quality of the Internet is very unstable, especially when the
university professors and students saturate the bandwidth. It is
important to point out that the NOM-037 establishes as an
obligation of the employer to provide their workers with all the
necessary equipment to be able to do their work in the Telework
modality, however; in this specific case the idea is to know if the
self-employed teachers have the conditions to adhere to such
modality of work.
Fuzzy Modeling of DC Motors using the stimulus-response method
Authors: González-Castolo Juan Carlos
Published: April 2024

In this paper gives a brief review of the traditional
modeling of direct current (DC) motors using the
stimulus response method is made and a method is
proposed to obtain an alternative model, using fuzzy
logic theory. The two models capture the behavior of
the DC motor in an acceptable manner. The connotation
of acceptable is because some characteristics of the DC
motor are disregarded, which do not have
repercussions, in practical terms, as error factors in its
study. The first model relates the analysis to the
classical forms of control theory, through a first-order
differential equation. The second model relates the
analysis to the principles of generalization of necessary
knowledge in reasoning and learning within the area of
Artificial Intelligence where fuzzy sets and a series of
if-then type rules are used. The fuzzy DC motor model
is very convenient, within the control context, when
using Artificial Intelligence paradigms but it not limited
to this area.

Authors: Solís-Leaños Karla
Published: April 2024

The nutritional label is a tool that helps parents to make
decisions about their eating plan, in order to make safe
purchases. The objective was to analyze the knowledge
that parents have about nutritional labeling and its impact
on food choices, for which an observational, prospective
and analytical study was used. A questionnaire made up
of 14 questions was applied to 36 settlers from a
community in the State of Zacatecas. As a result, it was
obtained that 97% do know the nutritional information
table, and of these 69% if it seems important to read and
understand the label, which influences when making the
choice of food purchases, more than half of the
population considers that the current design greatly
favors reading. It was concluded that although the
majority of the population already knows it, it is of vital
importance that the totality of this, in addition to
knowing it, fully understand it and take into account all
the nutrients or substances that may harm it and thus be
able to choose the best products for their diet and that of
the family and thus have a better nutritional status.

Authors: Enríquez-Raudy Alejandra
Published: April 2024

One of the markers to evaluate health in patients with
hemodialysis is the level of serum albumin, water overload
is a common complication in this type of people that can
affect albumin, the objective in this work was to know the
levels of serum albumin and its relationship with fluid
overload in patients with chronic renal failure on
hemodialysis. A descriptive, cross-sectional and analytical
study was carried out in a renal therapy unit of a private
hospital in the city of Zacatecas, the sample consisted of
50 patients of both sexes. The variables considered were
serum albumin, body mass index (BMI), water overload,
anthropometry and sociodemographic factors. An
intermediate negative correlation (-0.382) was found with
a p of 0.003, which suggests a significant association
between the two variables. These results are of clinical
relevance, since maintaining adequate levels of serum
albumin can contribute to the prevention or control of fluid
overload in these patients, which in turn can positively
impact their health and quality of life.

GIS as a tool to apply the universal equation of soil loss in the Sextin river basin
Authors: Servín-Prieto Alan Joel
Published: April 2024

Erosion is a process in which the superficial layer of the soil
is lost, which provides the plants with the highest
concentration of nutrients and the water they need, thanks to
its high organic matter content. According to the United
Nations Organization and Goal 2 'Zero Hunger' of the
Sustainable Development Goals, soil erosion is a factor that
restricts the ability to produce nutritious food. In this sense, it
is important to monitor this natural process, an effective
method is the implementation of the Universal Soil Loss
Equation, which is a quantitative method of indirect
evaluation that can be used through Geographic Information
Systems in a determined area, in this method variables such
as topography, land slope, land use, site geology, and average
annual rainfall. The study site of this research is the Sextín
River Basin located northwest of the State of Durango,
Mexico, with a surface area of 4,906.8 km2. The results
obtained indicate that the rate of soil loss reaches a value of
27,201 tons/ha/year, corresponding mainly to areas where the
topography presents a high percentage of its slopes.
Design of a p-i-n type inverted perovskite solar cell using SiOx as down-conversion material to improve PCE: Simulation and optimization in SCAPS-1D
Authors: Paz-Totolhua Ezequiel
Published: April 2024

In this research work, an inverted p-i-n type perovskite
solar cell: ITO/PEDOT: PSS/CH3NH3PbI3/PCBM/Au has
been simulated and optimized in SCAPS-1D. The
optimized parameters in SCAPS-1D that improved solar
performance were: perovskite thickness, the total defect
density of perovskite, the total defect density of interfaces,
series and shunt resistances, and device operating
temperature. As a result, the efficiency (PCE) increased to
18.33%. Subsequently, when the silicon-rich oxide (SiOx)
material was implemented in the simulation as downconversion energy material on the outside of the cell, a
power conversion efficiency (PCE) of 23.7% was
obtained. The SiOX film obtained experimentally by
sputtering obtained good photoluminescence, absorption
coefficient, band gap, and transmittance characteristics
before and after thermal annealing. These characteristics
have been considered for the proposed device. It is
indicated that the inverted perovskite solar cell of type pi-n: SiOx/ITO/PEDOT:PSS/CH3NH3PbI3/PCBM/Au has
better J-V output values and EQ quantum efficiency than
the perovskite solar cell without SiOx.
Fuzzy control design to pose mechanical structures used in solar farms
Authors: Castillo-Minjarez José Miguel Angel
Published: April 2024

Solar panels have problems in terms of the optimal
capture of solar energy, reducing their efficiency due to
the static position they maintain throughout the year.
This article presents the proposal for the development
of a fuzzy control to position a mechanical structure,
which supports a solar panel seeking to obtain
maximum capture in solar farms. The fuzzy control law
defines rules that together cause a nonlinear control law
by evaluating the performance of the controller through
graphics and its simulation in the MatLab Simulink®
software. The mechanical structure used has an
arrangement of photoresistors at the ends of the surface,
which determined the desired elevation angle,
generating the control setpoint. Three experiments were
developed to validate the operation of the resulting
controller, concluding that the diffuse system decreases
the position error with respect to the incidence of solar
radiation on the photovoltaic cells and the rotational
movement of the Earth.

Precision analysis of the integration rules used for transient simulation in electric networks
Authors: Galván-Sánchez Verónica Adriana
Published: April 2024

The adequate selection of the integration rule and time step is
crucial to ensure accurate results in the simulation of an
electric network. For this reason, this work has two main
objectives: to analyze the distortion of the waves due to the
integration rule and integration time step, and to provide
guidelines for new circuit simulators’ users on how to
properly choose an integration rule and a time step according
to a desired precision. When discretizing a continuous
system, the frequency response of the discrete system can be
used to evaluate the precision of the mentioned rule, since a
discrete system can be viewed as a filter. However, the
frequency response provides the accuracy of the discrete
system during the steady state; the transient-state accuracy
can be analysed by evaluating the pole distortion due the
discretization. This work focuses on the analysis of the
steady-state accuracy and the transient-state accuracy of two
discrete systems: an RL branch used as a fist order system and
an RLC branch used as a second order system. For this
analysis, two commonly used discretization rules are
considered, backward Euler and trapezoidal rules.

KINEMATIC SIMULATION AND EXPERIMENTAL ANALYSIS OF A ROLLER BRANCH PICKING MECHANISM
Authors: YANG Aiqian , LI Hui , ZHANG Junfang , YANG Xin
Published: April 2024

Apple tree branches have the physical characteristics of high cellulose content and high elasticity, and the use of traditional soft straw pickers will miss a large number of branches. It is necessary to design a picking mechanism that adapts to the physical characteristics of fruit tree branches. In the treatment of branches in modern orchards, the picking mechanism is an important part of the picking device. The success rate of picking directly affects the processing performance of the whole machine. To improve the picking rate, the roller branch picking mechanism is studied. The trajectory of the roller picking and the stress state of the branches are analyzed, and five main factors affecting the picking effect are obtained, i.e. the position relationship between the rotation center of the picking roller and the feeding roller, inclination angle of the steel teeth, the effective working length, the speed and the forward speed of the machine. A mathematical model is established to obtain the static and dynamic motion trajectories of the roller picking mechanism are obtained by using Matlab. Taking the analysis results of influencing factors as the optimization goal, the picking trajectory of the mechanism is simulated to obtain a set of non-inferior solutions. A roller branch picker is manufactured according to the parameter values and tested in the field, and the picking rate can reach 91%.
