A Sensor for Spirometric Feedback in Ventilation Maneuvers during Cardiopulmonary Resuscitation Training
Authors: Leocádio Rodolfo Rocha Vieira , Segundo Alan Kardek Rêgo , Louzada Cibelle Ferreira
Published: November 2019

This work proposes adapting an existing sensor and embedding it on mannequins used in cardiopulmonary resuscitation (CPR) training to accurately measure the amount of air supplied to the lungs during ventilation. Mathematical modeling, calibration, and validation of the sensor along with metrology, statistical inference, and spirometry techniques were used as a base for aquiring scientific knowledge of the system. The system directly measures the variable of interest (air volume) and refers to spirometric techniques in the elaboration of its model. This improves the realism of the dummies during the CPR training, because it estimates, in real-time, not only the volume of air entering in the lungs but also the Forced Vital Capacity (FVC), Forced Expiratory Volume (FEVt) and Medium Forced Expiratory Flow (FEF20–75%). The validation of the sensor achieved results that address the requirements for this application, that is, the error below 3.4% of full scale. During the spirometric tests, the system presented the measurement results of (305 ± 22, 450 ± 23, 603 ± 24, 751 ± 26, 922 ± 27, 1021 ± 30, 1182 ± 33, 1326 ± 36, 1476 ± 37, 1618 ± 45 and 1786 ± 56) × 10−6 m3 for reference values of (300, 450, 600, 750, 900, 1050, 1200, 1350, 1500, 1650 and 1800) × 10−6 m3, respectively. Therefore, considering the spirometry and pressure boundary conditions of the manikin lungs, the system achieves the objective of simulating valid spirometric data for debriefings, that is, there is an agreement between the measurement results when compared to the signal generated by a commercial spirometer (Koko brand). The main advantages that this work presents in relation to the sensors commonly used for this purpose are: (i) the reduced cost, which makes it possible, for the first time, to use a respiratory volume sensor in medical simulators or training dummies; (ii) the direct measurement of air entering the lung using a noninvasive method, which makes it possible to use spirometry parameters to characterize simulated human respiration during the CPR training; and (iii) the measurement of spirometric parameters (FVC, FEVt, and FEF20–75%), in real-time, during the CPR training, to achieve optimal ventilation performance. Therefore, the system developed in this work addresses the minimum requirements for the practice of ventilation in the CPR maneuvers and has great potential in several future applications.
A Sequential Framework for Improving Identifiability of FE Model Updating Using Static and Dynamic Data

Published: November 2019

By virtue of the advances in sensing techniques, finite element (FE) model updating (FEMU) using static and dynamic data has been recently employed to improve identification on updating parameters. Using heterogeneous data can provide useful information to improve parameter identifiability in FEMU. It is worth noting that the useful information from the heterogeneous data may be diluted in the conventional FEM framework. The conventional FEMU framework in previous studies have used heterogeneous data at once to compute residuals in the objective function, and they are condensed to be a scalar. In this implementation, it should be careful to formulate the objective function with proper weighting factors to consider the scale of measurement and relative significances. Otherwise, the information from heterogeneous data cannot be efficiently utilized. For FEMU of the bridge, parameter compensation may exist due to mutual dependence among updating parameters. This aggravates the parameter identifiability to make the results of the FEMU worse. To address the limitation of the conventional FEMU method, this study proposes a sequential framework for the FEMU of existing bridges. The proposed FEMU method uses two steps to utilize static and dynamic data in a sequential manner. By using them separately, the influence of the parameter compensation can be suppressed. The proposed FEMU method is verified through numerical and experimental study. Through these verifications, the limitation of the conventional FEMU method is investigated in terms of parameter identifiability and predictive performance. The proposed FEMU method shows much smaller variabilities in the updating parameters than the conventional one by providing the better predictions than those of the conventional one in calibration and validation data. Based on numerical and experimental study, the proposed FEMU method can improve the parameter identifiability using the heterogeneous data and it seems to be promising and efficient framework for FEMU of the existing bridge.

Published: November 2019

In this paper we propose and investigate a novel magnetic field sensor based on a Tri-microfiber coupler combined with magnetic fluid and a fiber Bragg grating (FBG) in a ring. A sensitivity of 1306 pm/mT was experimentally demonstrated in the range of magnetic fields from 0 to 15 mT. The reflection peak in the output spectrum associated with the FBG serves as a reference point allowing to avoid ambiguity in determining the spectral shift induced by the magnetic field. Due to its high sensitivity at low magnetic fields, the proposed structure could be of high interest in low field biosensing applications that involve a magnetic field, such as magnetic manipulation or separation of biomolecules.
Performance Analysis of Addressing Mechanisms in Inter-Operable IoT Device with Low-Power Wake-Up Radio
Authors: Song Taewon , Kim Taeyoon
Published: November 2019

Internet of Things (IoT) technology is rapidly expanding the use of its application, from individuals to industries. Owing to this, the number of IoT devices has been exponentially increasing. Considering the massive number of the devices, overall energy consumption is becoming more serious. From this point of view, attaching low-power wake-up radio (WUR) to the devices can be one of the candidate solutions to deal with this problem. With WUR, IoT devices can go to sleep until WUR receives a wake-up signal, which enables a significant reduction of its power consumption. Meanwhile, one concern for WUR operation is the addressing mechanism, since operational efficiency of the wake-up feature can significantly vary depending on the addressing mechanism. We therefore introduce addressing mechanisms for IoT devices equipped with WUR and analyze their performances, such as elapsed time to wake up, false positive probability and power/energy consumption, to provide appropriate addressing mechanisms over practical environments for IoT devices with WUR.

A low voltage (−20 V) operating high-energy (5.48 MeV) α-particle detector with a high charge collection efficiency (CCE) of approximately 65% was observed from the compensated (7.7 × 1014 /cm3) metalorganic vapor phase epitaxy (MOVPE) grown 15 µm thick drift layer gallium nitride (GaN) Schottky diodes on free-standing n+-GaN substrate. The observed CCE was 30% higher than the bulk GaN (400 µm)-based Schottky barrier diodes (SBD) at −20 V. This is the first report of α–particle detection at 5.48 MeV with a high CCE at −20 V operation. In addition, the detectors also exhibited a three-times smaller variation in CCE (0.12 %/V) with a change in bias conditions from −120 V to −20 V. The dramatic reduction in CCE variation with voltage and improved CCE was a result of the reduced charge carrier density (CCD) due to the compensation by Mg in the grown drift layer (DL), which resulted in the increased depletion width (DW) of the fabricated GaN SBDs. The SBDs also reached a CCE of approximately 96.7% at −300 V.
Exploring the Laplace Prior in Radio Tomographic Imaging with Sparse Bayesian Learning towards the Robustness to Multipath Fading
Authors: Wang Zhen , Guo Xuemei , Wang Guoli
Published: November 2019

Radio tomographic imaging (RTI) is a technology for target localization by using radio frequency (RF) sensors in a wireless network. The change of the attenuation field caused by the target is represented by a shadowing image, which is then used to estimate the target’s position. The shadowing image can be reconstructed from the variation of the received signal strength (RSS) in the wireless network. However, due to the interference from multi-path fading, not all the RSS variations are reliable. If the unreliable RSS variations are used for image reconstruction, some artifacts will appear in the shadowing image, which may cause the target’s position being wrongly estimated. Due to the sparse property of the shadowing image, sparse Bayesian learning (SBL) can be employed for signal reconstruction. Aiming at enhancing the robustness to multipath fading, this paper explores the Laplace prior to characterize the shadowing image under the framework of SBL. Bayesian modeling, Bayesian inference and the fast algorithm are presented to achieve the maximum-a-posterior (MAP) solution. Finally, imaging, localization and tracking experiments from three different scenarios are conducted to validate the robustness to multipath fading. Meanwhile, the improved computational efficiency of using Laplace prior is validated in the localization-time experiment as well.

Published: November 2019

African swine fever (ASF) is one of the most threatening diseases for the pig farming sector worldwide. As an effective vaccine is lacking, strict application of control measures is the only way to fight the disease in both industrial farms and backyard holdings. With generally low biosecurity standards, the latter are at particular risk for disease introduction and offer challenging conditions for disease control. In the following case report, we describe the overall course of an ASF outbreak in a Bulgarian backyard farm and the implemented control measures. Farm facilities and available data have been investigated to estimate the possible source, spread and time point of virus introduction. Contact with contaminated fomites entering the stable via human activities was regarded to be the most likely introduction route. The slow disease spread within the farm contributes to the hypothesis of a moderate contagiosity. As no further ASF outbreaks have been detected in domestic pig farms in the region, it could be demonstrated that successful disease control in small-scale farms can be reached. Thus, the report contributes to a better understanding of ASF in the backyard sector.

Pangan lebih dari sekedar komoditas yang diperjualbelikan. Ia juga lebih dari sekedar nutrisi, pangan terkait dengan budaya psikologi hinga kebutuan sosial manusia. Konsep ketahanan pangan yang berlaku tidak berbeda jauh dengan ketahanan pangan yang ada dalam Islam akan tetapi suatu perbedaan yang mendasar, ketahanan pangan dalam Islam dikaitkan dengan keimanan kepada Allah S.W.T. Terkait dengan maqashid syari’ah yaitu, menjaga agama, jiwa, akal, kehormatan dan harta benda. Bahkan pangan dalam keadaan tertentu bisa lebih menjadi prioritas dari pada ibadah itu sendiri.Dengan metode deskriptif komparatif penulis membandingkan konsep ketahanan pangan yang berlaku di Indonesia dan berbagai negara muslim lainya dengan ketahanan pangan yang pernah adadalam Islam serta pencapaian yang pernah diraihnya, seperti ketahanan pangan pada masa Umar bin Khatab, sampai masa Turki Usmani. Pencapaian ketahanan pangan yang menerapkan syari’at Islam adakalanya dicapai dengan sistim khuraj, serta kepemilikan tanah(Land Reform) yang pernah gagal diusahakan oleh Soekarno dan berhasil direalisaskian sampai berabad-abad yang dimulai pada masa Rasulullah S.A.W. Tidak hanya sampai di situ bahkan pada masa Turki Usmani, Imperium yang sudah mulai lemah ini telah memliki andil dalam menyelamatkan nyawa masyarakat Irlandia yang kelaparan.

Pendikan bertujuan mencapai pertumbuhan yang seimbang dalam kepribadian manusia secara total, melalui pelatihan spiritual, kecerdasan, rasio, perasaan dan panca indra. Oleh karena itu pendidikan memberikan pelayanan bagi pertumbuhan manusia dalam segala aspeknya;spiritual, intelektual, imaginasi, fisik, ilmiah, linguistic, baik individu maupun kolektif, kearah kebaikan dan pencapaian kesempurnaan. Al-Syaibaniy : filsafat bukanlah hikmah itu sendiri, melainkan cinta terhadap hikmah dan berusaha mendapatkannya. Juga dapat pula mencari hakikat sesuatu, berusaha menautkan sebab akibat, dan  berusaha menafsirkan pengalamanpengalaman manusia. Filsafat pendidikan adalah filsafat yang  memikirkan tentang masalah kependidikan. Oleh karena ada kaitan dengan pendidikan, maka filsafat diartikan sebagai teori pendidikan dalam semua tingkat. Filsafat mengkaji dan memikirkan tentang hakikat segala sesuatu secara menyeluruh, sistematis, terpadu,universal dan radikal yang hasilnya penjadi pedoman dan arah bagi perkembangan ilmu-ilmu yang bersangkutan. Pendidikan selalu diwarnai oleh pandangan hidup (way of life). Diantara pandangan hidup ialah rasionalisme. Rasionalisme ialah faham yang mengatakan bahwa kebenaran diperoleh melalui akal dan diukur dengan akal. Akal itulah alat pencari dan pengukur kebenaran. Maka filosofis pendidikan sangat penting, karena dalam proses pendidikan, kebenaran menjadi tujuan. Al-Attas (dalam Ahmad Tafsir) tujuan pendidikan Islam adalah menjadi manusia yang baik, maka tujuan pendidikan Islami adalah terbentuknya orang yang berkepribadian muslim, dengan demikandiperlukan pandangan hidup yang kokoh dan komprehensif, serta tidak mudah berubah.
PERKEMBANGAN JIWA KEAGAMAAN PADA USIA LANJUT

Published: November 2019

Ilmu Jiwa Agama berbeda dengan cabang-cabang Ilmu Jiwa lainnya, karena dikaitkan dengan dua bidang pengetahuan yang berlainan sama sekali, sebagian harus tunduk kepada agama dan sebagian lainnya tunduk kepada Ilmu Jiwa. Dengan kata lain Psikologi Agama atau Ilmu Jiwa Agama, meneliti pengaruh agama terhadap sikap dan tingkah orang atau mekanisma yang bekerja dalam diri seseorang karena cara seseorang berfikir, bersikap, bereaksi dan bertingkah laku, tidak dapat dipisahkan dari keyakinannya, karena keyakinan itu masuk dalam konstruksi kepribadiannya.

Sehubungan dengan kebutuhan manusia dari periode perkembangan tersebut, maka dalam kaitannya dengan perkembangan jiwa keagamaan akan dilihat bagaimana pengaruh timbal balik antara keduanya. Dengan demikian, perkembangan jiwa keagamaan akan dilihat dari tingkat usia.

Di dalam Islam perlakuan terhadap manusia usia lanjut dianjurkan seteliti dan seteladan mungkin. Perlakuan terhadap orang tua yang berusia lanjut, dibebankan pada keluarga mereka, bukan kepada badan atau panti asuhan, termasuk panti jompo. Sehingga merawat orang tua dalam usia lanjut merupakan kewajiban bagi anak-anak maupun sanak keluarganya, yakni dengan cara-cara yang diajarkan di dalam alQuran dan Sunnah Rasul.

Rhétorique et prédication selon Calvin
Authors: Peter Rodolphe
Published: November 2019

La prédication chrétienne se doit de lutter contre deux tentations inverses auxquelles elle cède si facilement : celle de verser dans la grandiloquence sous prétexte de capter l'auditoire, celle de négliger la forme sous prétexte d'inspiration. Calvin, par sa formation humaniste d'une part et sa vocation théologique d'autre part, a su éviter ce double écueil. Selon le réformateur « l'éloquence qui convient à l'Esprit de Dieu, c'est celle qui n'est point enflée d'ostentation et ne se perd point en l'air par vaines bouffées, mais est solide et pleine d'efficace, et a plus de sincérité que d'élégance » (Commentaire sur I. Cor. 1, 17 : CO XLIX, c. 322)

Published: November 2019

Les noms propres inscrits sur l'ostracon araméen de Nimroud, qui date de la fin du 8e siècle, ont été attribués, pour la plupart, à des Israélites du royaume de nord, mais l'apparition récente de sceaux ammonites amène à tempérer cette affirmation ; en effet, si les théophores de YHWH sont absents de cet ostracon, ceux de El, caractéristiques de l'onomastique ammonite, y sont par contre nombreux. La présence de 5 noms, connus à la fois en hébreu et en ammonite, et celle de 3 noms typiquement ammonites pourrait témoigner des relations entre l'Assyrie et la Transjordanie.

Published: November 2019

The conditions of production and the most relevant directions of development of technology and equipment of cold rolling mills for the production of thin flat rolled steel are investigated, analyzed and summarized. A comparative analysis of cold rolling technology is carried out, which is implemented in continuous and reversed modes of mill. The technological limitations and criteria for the development of deformation modes on cold rolling strip mills, which allow to expand the assortment towards a smaller thickness, are given. A method for determining the thickness is proposed, and a series of thicknesses of thin (1.5-1.8 mm) hot-rolled break-down are recommended for the production of tinplate of single rolling and thin strips of high quality. The method of calculation schedule drafting on a specific mill is developed. The technique of determination of the smallest thickness of a strip on a concrete mill is presented, taking into account the influence of rigidity of the working cage and features of the force load of the roller node with a decrease in the thickness and width of the strip. The use of the above materials allows to select and justify the optimal variant of cold band rolling technology, as well as to develop rational deformation modes that ensure the implementation of the cold rolling process with maximum efficiency, given the desired range and the required volume of thin cold-rolled sheet steel or tinplate. As a result of taking into account the features of the force interaction of the thin strip with the rolls during cold rolling and the rigidity of the working stands of the mill, the accuracy and reliability of determining the parameters are increased, it opens additional possibilities for expanding the range of cold rolling mills towards smaller thicknesses.

Published: November 2019

An integral component of modern technogenic activities using nuclear energy is the accumulation of radioactively contaminated metals. Solving the issues of recycling or returning these metals to reuse is inextricably linked to ensuring the radiation safety of people and the environment at all stages of the technological cycle using radioactive metal. Possible consequences of the effect of ionizing radiation on the human body are considered, the features of radioactively contaminated metal as a possible source of radiation for production personnel are investigated, as well as the analysis of radiation safety of the utilization of radioactively contaminated metal by its melting using self-deactivation effect. It is noted that an important element of the complex of measures for radiation safety of production personnel is the assessment of the radiation situation, and its main purpose and overall content is indicated. The basic principles of radiation safety are formulated. The choice of rational options for the actions of production personnel in the disposal of radioactive contaminated metal eliminates the exposure of people to radiation levels that exceed standard values. Additional radiation exposure to the environment is also excluded. It is shown that the criterion of radiation safety of a metal is the maximum dose rate of gamma radiation from its surface, which ensures that the limit of the individual annual effective radiation dose is not exceeded. It is reasonable to review the permissible levels of radiation exposure of personnel performing operations with radioactively contaminated metal in accordance with the procedure established by the Ministry of Health of Ukraine. A multistage system for cleaning ventilation emissions from a melting furnace using an electrostatic filter at the last stage, which directly cleans gas aerosol emissions from radionuclides, is proposed.
The results of the study can contribute to the return to production of large volumes of radioactively contaminated metal, significantly improve the technical and economic performance of metal production and help to prevent environmental disturbances.

Published: November 2019

Article is devoted to the questions of structuring regularities detection in sodium silicate – sand mixtures and possibility of forecasting and changing their properties determination. Studies have been performed using quartz sand and sodium silicate solute, and also quartz sand placket with sodium silicate solute. It has been discovered that sand flow ability does not depend on the size of its particles, and the largest value acquires with the content of free water (moisture) less than 0.2% by weight. It has been established that apparent density of rare and placket sand, compacted by vibration, is additive to fractional mass content in it of particles normalized fractions and increases from 1100 to 1900 kg/m3 with average size of its grains decreasing from 0.82 to 0.16 mm and with their fineness modulus increasing from 20 to 60. According to experimental data, analytical relationship between content of sodium silicate in sodium silicate solute and specific density of sodium silicate solute has been elaborated. Estimation of sodium silicate solute drying method influence on residual water content in it has been realized. It has been shown that depending on sodium silicate solute amount in mixture, its physical state up to the time of mixture structuring beginning and method of solidification, the structure of solidified sodium silicate solute in structured sodium silicate – sand mixture may vary from dense-oriented to foam-disoriented, contain or not contain residual water. Obtained data using and recording will allow not only reduce the cost of new sodium silicate – sand mixtures developing, increase prediction of their properties accuracy, but also open a new direction for methods of their implementation in foundry molds and rods production.

The use of indicators provides several benefits among which the effective evaluation in the financing of agricultural loans to borrowers and also the support to the credit manager and portfolio in making strategic decisions. Despite the relevance of using metrics to aid in the financing of agricultural credit given the diversity of the existing business model, organizations have neglected their practice. Reasons for this fact include: (i) although access to credit is an significant factor in the adoption of agricultural technologies and increased agricultural incomes among rural farmers, are generally not sufficiently mature to make use of measurements or 2) researchers are not yet widely aware of the need for exploratory studies that identifies a mechanism to propose an agricultural credit financing strategy based on indicators through the analysis of a set of metrics. In this context, this article aims to conduct a systematic review to collect evidence on the existence of metrics and indicators that are specific for financing agricultural loans to rural families. The study produced 64 articles selected from the current literature and were not repeated because they were relevant.

La metodología es de carácter empírico y se basa en la fórmula racional de Mulvaney junto con la expresión de Kieffer y Chu para las curvas IDR, siendo aplicada a 5 cuencas urbanas de Rosario, considerando un escenario base (actual) de uso del suelo y 3 escenarios futuros con/sin disponibilidad de espacios verdes. En este trabajo se valida la metodología empírica aplicando una estimación estadística convencional a las cuencas anteriores. La misma contempla la estimación de parámetros geomorfológicos e hidrológicos de las cuencas para el escenario base y los escenarios futuros, aplicando el Colorado Urban Hydrograph Procedure, CUHP. Se procesan series pluviométricas de Rosario Aero (71 años de extensión, alrededor de 7000 eventos) construyendo hietogramas de lluvia total y neta mediante un coeficiente de escorrentía por cuenca y escenario. Se generan series de caudales diarios y se seleccionan los máximos anuales, asignándoles leyes de distribución de probabilidad (Gumbel). Finalmente, para cada cuenca y escenario se obtienen los cambios de probabilidad de excedencia para las series actuales y futuras de caudales. Al comparar los resultados con la metodología empírica se alcanzan coeficientes de correlación muy altos (0.9975) y coeficientes de eficiencia de Nash-Sutcliffe elevados (0.9929). Consecuentemente la metodología denominada empírica constituye una simple y efectiva herramienta para estimar los cambios en el riesgo de inundación ante cambios de uso del suelo evaluados a través del coeficiente de escorrentía.

In this research, we focus on the study of the operating conditions that influence on suspension process for obtaining (co)polymers of styrene with polar monomers (copolymers of styrene with acrylate of butyl (S-BA) and copolymers of styrene with vinyl acetate (S-VAc)) using the technique of conventional free radical polymerization (FRP). At higher agitation speed, the reaction performance decreases. Likewise, the influence of the molecular weight of the dispersing agent, in this case polyvinyl alcohol (PVA), influences the polymerization performance was also observed. That is, at a higher molecular weight of PVAs, there is an increase in the particle size of the bead and in the polymerization yield. Finally, there is an influence of the polar part on the copolymer both for the yield and for the particle size of the bead. When obtaining copolymers of S-VAc, the yield is lower compared to the respective styrene homopolymer and higher in the S-BA.

The production of artificial polymers is, today, one of
themost important activities of the chemical industry,
polymersare widely used in everyday life, as, there are
different types of polymers, they can be used for different
uses. These polymeric materials have unique mechanical,
physical and chemical properties, which most other
materials do not possess, not to mention that its cost is
lower than the other materials. The present research work
focuses on the determination of optimal operating
conditions for the polymerization of styrene and methyl
methacrylate in a Batch reactor, as well as the influence
of inorganic salt in this case NaCl in the performance of
reaction and in the size of the material polymer, through
the process of suspension using a synthetic route of
polymerization by radical free conventional (FRP), where
viscometry to the polymeric material testing was
performed for this way characterize it, and to determine
factors of interest such as the molecular weight, etc.

This paper presents the experiments and results on the viral
and bacterial pneumonia identification, which were obtained
by means of image processing techniques and artificial
neural networks. The objective of this research is to reduce
the patient’s waiting time to obtain the result of the x-rays
diagnosis of a pulmonary disease of pneumonia. At the time
of this writing, pneumonia is considered the most common
cause of infant mortality in the world, responsible for 15%
of all deaths in children under 5 years. To obtain the
classifier model we start from the detection in the
pulmonary region through digital image processing and
obtaining the characteristics in the segmented images,
discriminating against those that provide a diagnosis
through Gray Level Co-occurrence Matrix (GLCM).
Finally, those features are used as the description in the
classification of images such as: healthy, viral pneumonia
and bacterial pneumonia. We use a total of eight features:
autocorrelation, contrast, cluster prominence, variance
cluster shade, sum of entropy, difference of entropy and
number of pixels. These characteristics were used to model
and train an artificial neural network Backpropagation,
obtaining results that are presented in their confusion matrix
along with the accuracy percentage obtained.

The characterization of wind speed in Cancun, Q. Roo Mexico, had as objectives: 1. To estimate the efficiency and energy produced by a 400W wind turbine at a height of 10 m; 2. To carry out the wind speed characterization. The methodology used was the Weibull distribution. In order to calculate the distribution of the wind speed, with the Wind Rose software we analyzed the energy in different directions and the calculation of potential wind energy based on Rayleigh's analysis. The results showed: that the power generated from the wind speed calculated in (PV) 2.8 m/s was 1.48 W, its capacity factor at 0.004 which does not reach the permissible range of 0.25 to 0.40; the energy produced annually was 14.02 kW/year, it is required to raise the wind turbine to 13.4 m, to reach 12 m/s speed and to be efficient to install a 400 W wind turbine. The paper identifies the preliminary activities and illustrates the method of calculation of wind characterization and energy produced to define the installation conditions of the wind turbine. It also contributes to the scientific advance by estimating the characterization of the wind in Cancun Quintana Roo, Mexico, for future wind turbine installations.

For centuries, humans have attempted to improve their living conditions, seeking to facilitate their daily tasks and in the industry, seeking to improve production processes, in order to be more competitive and generate greater wealth through their work, trying to avoid work risks and accidents, improve product quality and production times, as well as downtime. The design proposed for this work is that of a roller conveyor by gravity, controlled and monitored by PLC, sensors, dosers, and data matrix cameras, in order to have internal control of the manufacturing process of the Carrier piece. The automation of this conveyor line will reduce transport times between each work operation, eliminating unnecessary movements and increasing mobility in each work operation. This will help increase production, in addition to reducing mishandling of the piece caused by the wrong manipulation of the operator.
