Design of a Customized Intelligent Electronic Device for Power Circuit Safety
Authors: Ebby Darney P.
Published: September 2022

The Intelligent Electronic Devices (IEDs) are widely used to control the power circuits through an automated control device. The main motive of IEDs is to monitor the power flow, enable the control process and meter the changes. In some cases, the IEDs are employed as an electronic circuit breaker for providing a reliable operation. It is achieved by operating the relays through digital signals. The traditional methods have been using a mechanical system for operating the circuit breakers, which requires a manual operation for resting the breakers. The modern IEDs are developed to reset the operation by its own but such systems are heavily affected through data intrusions. Therefore, a programmed IED is developed in the proposed work to analyze if the decisions made by the IEDs are original or fake in a simulated observation. It is done with a mathematical averaging algorithm with respect to time for estimating a threshold. The experimental outcome indicates that the performance of the customized IED is better over the traditional IEDs. Moreover, the proposed device saves the energy distribution in a power system by avoiding the fake operations created in the IEDs through external intrusions.

Authors: Zwalbong Nimfa F. , Abubakar Hauwa L. , Ibrahim Umar Abbas
Published: September 2022

The study examined the effect of financial reforms on the performance of quoted manufacturing firms in Nigeria. The study used an expo-facto research design. The study population comprises 44 manufacturing companies quoted at [1], which include Agriculture, Conglomerates, Consumer goods, Healthcare / Pharmaceuticals, Industrial goods, and Natural Resources. Thus, using a study period of 10 years (2010 – 2019) data on financial sector reforms (financial deepening, domestic credit, liquidity, market capitalisation, exchange rate and interest rate) carried out in Nigeria, being the independent variable and on performance (capacity utilization). Panel structured secondary data were collected and analyzed using the Generalized Moment of Methods (GMM) in STATA 15. The financial reform indicators: financial deepening (FDP), domestic credit, market capitalization, liquidity and exchange rate have p-values less than 0.05 (5%) level of significance, thus implying that the financial reforms’ indicators affect the performance as proxied by the capacity utilization of the manufacturing firms in Nigeria. Although, the interest rate which is one of the indicators of financial reforms returns a p-value greater than 0.05 (5%) and thus not having significant effect on the performance of the firms. The study suggested that the manufacturing firms should put measures to optimize the use of accessible funds to ensure optimal capacity utilization, as this will translate into increased productivity, profitability, and financial stability. The government should vigorously pursue monetary policies to ensure the injection of funds into the financial sector, to enhance the capacity of deposit money banks to allocate more credit to the sector at affordable rates. This will enable the optimal operation of the manufacturing sector in Nigeria.

Authors: Bayón Arnau Luis , Río García Juan Carlos , Loredo Fernández Enrique , Suárez Rodríguez Pedro
Published: September 2022

Recientemente varios países desarrollados han reestructurado sus respectivos sistemas eléctricos , y España se ha incorporado a este nuevo proceso promulgando diversas leyes para definir la Nueva Regulación del Sistema Eléctrico Nacional. Como consecuencia el problema de la coordinación hidrotérmica atendiendo a la optimización de múltiples factores va a ser un reto fundamental con el que se tendrán que enfrentar las compañías generadoras de electricidad. A continuación se expone un sistema de optimización basado en el empleo del método de Ritz para resolver este problema, que consiste en el cálculo de las potencias generadas en las centrales, tanto térmicas como hidráulicas, de un sistema hidrotérmico, para que un funcional múltiple, sea lo más pequeño posible, teniendo en cuenta diversos factores que intervendrán en el problema en forma de restricciones que se tendrán que cumplir necesariamente. Una novedad importante de este método es que permite incluir varios factores, como el coste asociado a la contaminación y también se considera el retraso en el transporte que es el tiempo que tarda en fluir el agua de una central a otra.

Cooperación entre empresas versus cooperación Universidad-Empresa: criterios para la selección de socios en acuerdos de cooperación tecnológica
Authors: Mora Valentín Eva María
Published: September 2022

La elección del socio con el que llevar a cabo un acuerdo de cooperación tecnológica resulta un aspecto fundamental en las fases iniciales del proceso de colaboración. Teniendo en cuenta que la naturaleza de los diversos agentes con los que cooperar es muy variada (clientes, proveedores, competidores, institutos de investigación, universidades ...), parece razonable que el problema de la selección del socio se aborde considerando las características propias de cada agente. Sin embargo, la mayoría de los estudios que existen al respecto son demasiado generalistas y no tienen en cuenta las particularidades de los socios potenciales. El presente trabajo analiza los criterios que deben considerarse ante la disyuntiva de si cooperar con una empresa o con una universidad. Para ello, se parte de la hipótesis de que los factores a considerar no serán los mismos para elegir a un socio de entre varias empresas, que para elegir entre una universidad y una empresa.

La dependencia en los canales de distribución: un análisis de sus factores determinantes desde la perspectiva del fabricante
Authors: Méndez García de Paredes José Luis , Oubiña Barbolla Javier
Published: September 2022

El sector minorista de los canales de distribución de productos de gran consumo en España está experimentando un intenso proceso de concentración que afecta a las relaciones de poder existentes entre fabricantes y distribuidores. La literatura relativa al poder establece, como principal base del mismo, la dependencia que muestra una organización frente a otra debido a la necesidad de utilizar los recursos proporcionados por la segunda compañía para conseguir sus objetivos. En la presente comunicación, se analizan los factores que determinan la dependencia del fabricante respecto al distribuidor, entre los cuales destacan por su importancia, el volumen de ventas, las inversiones específicas en la transacción y el poder compensador. El estudio se completa con la realización de un trabajo empírico realizado a una muestra de fabricantes de productos de gran consumo, que tras la aplicación de la técnica estadística de la regresión múltiple, permite identificar al volumen de ventas, como principal factor explicativo de la dependencia del fabricante respecto al distribuidor. Este hecho pone de manifiesto la relevancia del proceso de concentración que está teniendo lugar en el sector minorista.

Published: September 2022

Stunting is a short or very short state that is based on height according to age. Factors that influence the occurrence of stunting consist of direct factors, indirect factors, and the root of the problem. Environmental factors are indirect factors for the incidence of stunting, where a history of infectious diseases is a link between environmental factors and stunting events. The purpose of this study is to determine the relationship between environmental factors and a history of diarrheal disease to the incidence of stunting in baduta aged 6-23 months in 2021 in the work area of the Ciawi Health Center, Tasikmalaya Regency. The research method used is a quantitative method with a case-control research design. The sample in this study was 102 Badura mothers consisting of 51 stunted baduta mothers and 51 non-stunted baduta mothers. The statistical test used is Chi-Square with (α) = 0.05. The results of the study found that there was a relationship between a history of diarrhea (p-value = 0.031, OR = 5.976), access to sanitation (p-value = 0.034, OR = 4.02) and access to drinking water (p-value = 0.006, OR = 4.453) with stunting events. Meanwhile, there is no relationship between access to sanitation (p-value = .1,000) and access to drinking water (p-value = 0.482) with a history of diarrhea. The conclusion of this study is that the variables associated with stunting events are a history of diarrhea, access to sanitation, and access to drinking water. Meanwhile, access to sanitation and access to drinking water is not related to a history of diarrhea. It is hoped that households can improve sewage channels so that access to sanitation is safe and drinking water sources are safe for consumption.Keywords: Stunting; Baduta; History of Diarrhea; Sanitation; Drinking Water

AbstractPoor maternal knowledge of nutrition and health is one of the causes of malnutrition in under-fives. Based on the research problem statement, the present work explores the effect of maternal knowledge on fish consumption in under-fives in the working area of Community Health Center Puskesmas Kabila, Bone Bolango, Regency.This study employed quantitative observation analysis that involved 251 under-fives aged 12 to 59 months selected using a quota sampling method. All univariate and bivariate data were analyzed using a chi-squared test.The result showed that most respondents have a poor understanding of the effect of parental or maternal knowledge on the dietary pattern (232 respondents, 92.4%). Furthermore, fish consumption is considered moderate, as seen in 221 respondents (88.0%). The chi-squared test revealed that the p-value of maternal knowledge is 0.000.In conclusion, maternal knowledge contributes to fish consumption in under-fives. It is expected that the research can provide information for Puskesmas Kabila Bone regarding the condition of people and fish consumption in children living in their working areas.Keywords: Knowledge, dietary pattern, fish, under-fives

While it is difficult to observe the first black hole seeds in the early universe, we can study intermediate-mass black holes (IMBHs) in local dwarf galaxies for clues about their origins. In this paper we present a sample of variability-selected active galactic nuclei (AGN) in dwarf galaxies using optical photometry from the Zwicky Transient Facility (ZTF) and forward-modeled mid-IR photometry of time-resolved Wide-field Infrared Survey Explorer (WISE) co-added images. We found that 44 out of 25,714 dwarf galaxies had optically variable AGN candidates and 148 out of 79,879 dwarf galaxies had mid-IR variable AGN candidates, corresponding to active fractions of 0.17% ± 0.03% and 0.19% ± 0.02%, respectively. We found that spectroscopic approaches to AGN identification would have missed 81% of our ZTF IMBH candidates and 69% of our WISE IMBH candidates. Only nine candidates have been detected previously in radio, X-ray, and variability searches for dwarf galaxy AGN. The ZTF and WISE dwarf galaxy AGN with broad Balmer lines have virial masses of 105

We also determined a nuclear supernova fraction of 0.05% ± 0.01% yr−1 for dwarf galaxies in ZTF. Our ZTF and WISE IMBH candidates show the promise of variability searches for the discovery of otherwise hidden low-mass AGN.
Ranking Theoretical Supernovae Explosion Models from Observations of the Intracluster Gas

Published: September 2022

The intracluster medium (ICM) is a reservoir of heavy elements synthesized by different supernovae (SNe) types over cosmic history. Different enrichment mechanisms contribute a different relative metal production, predominantly caused by different SNe type dominance. Using spatially resolved X-ray spectroscopy, one can probe the contribution of each metal-enrichment mechanism. However, a large variety of physically feasible supernova (SN) explosion models make the analysis of the ICM enrichment history more uncertain. This paper presents a nonparametric probability distribution function analysis to rank different theoretical SNe yields models by comparing their performance against observations. Specifically, we apply this new methodology to rank 7192 combinations of core-collapse SN and Type Ia SN models using eight abundance ratios from Suzaku observations of 18 galaxy systems (clusters and groups) to test their predictions. This novel technique can compare many SN models and maximize spectral information extraction, considering all the individual measurable abundance ratios and their uncertainties. We find that Type II SNe with nonzero initial metallicity progenitors in general performed better than pair-instability SN and hypernova models, and that 3D SNIa models (with a white dwarf progenitor central density of 2.9 × 109 g cm−3) performed best among all tested SN model pairs.

Purpose: While tumor volume reduction following radiation has been documented in myxoid liposarcomas, it is unclear whether large tumors experience similar volume reduction to smaller tumors. Materials and Methods: MRI studies performed before and after completion of pre-operative radiation therapy (RT) were examined. Tumor sizes were noted and categorized as large versus small based on size >10 cm. Tumor volumes were calculated, and operative duration and major wound complications were recorded.Results: The median largest tumor dimension was 12.4 cm before RT and 8.7 cm after RT. The median tumor volume was 298.9 cm3 before RT and 106.9 cm3 after RT. There was no significant difference in the mean percent tumor volume reduction between large tumors and small tumors (p = 0.11, 56.3% vs. 64.5%). Operative duration most strongly correlated to post-RT MRI volume (R2=0.674, p<0.001). Despite volume reduction, tumors that were large on presentation were more likely to experience major wound complications post-operatively.Conclusion: Radiation appears to be as effective at reducing myxoid liposarcoma tumor volume in large and small tumors. However, large tumors on presentation appear more likely to experience wound complications despite tumor volume reduction. Future studies should investigate disease-related outcomes as a factor of volume reduction in myxoid liposarcoma.
