In modern industry, electric motors are essential components in a wide range of applications, from manufacturing production to transportation and power generation. These motors are critical in industrial machinery and equipment, and their proper functioning is crucial for maintaining operational efficiency and productivity. However, motors are susceptible to various types of faults that can be costly in terms of downtime, production loss, and repair expenses. Early detection of these faults is essential to prevent unscheduled shutdowns, reduce maintenance costs, and avoid workplace accidents. This paper proposes a low-cost, real-time fault detection system for motors placed on the Non-Drive End based on neural networks, aimed at improving operational efficiency and reducing maintenance costs in the industry.

This study estimates the economic costs of mining pollution on water resources for the years 2008 and 2009 based on the conceptual framework of Environmental Efficiency. This framework identifies such costs as the mining companies’ trade-off between increasing production that is saleable at market prices (desirable output) and reducing the environmental pollution that emerges from the production process (undesirable output). These economic costs were calculated from parametric and non parametric production possibility frontiers for 28 and 37 mining units in 2008 and 2009, respectively, which were under the purview of the National Campaign for Environmental Monitoring of Effluent and Water Resources, conducted by the Energy and Mining Investment Supervisory Agency (Osinergmin) in those years. The results show that the economic cost of mining pollution on water resources rose to U.S. $ 8...

Para evaluar el efecto de los costos laborales sobre el empleo es crucial tener estimaciones confiables de la elasticidad costo laboral de la demanda de trabajo. Usándose una base de datos emparejados a nivel de firmas y trabajador, estimamos una función de demanda no condicionada de trabajo de largo plazo, explotando información sobre trabajadores para corregir la endogeneidad en la determinación de los salarios. Evaluamos los efectos sobre el empleo y la pérdida de eficiencia social de los valores observados de las aportaciones de los empleadores impuestas por la legislación laboral (seguro de salud, capacitación e impuestos) así como de las deducciones a los trabajadores (seguridad social e impuesto a la renta). Encontramos que los costos laborales no salariales reducen el empleo en 17% para los empleados y en 53% para los obreros, con pérdidas de eficiencia social asociadas ...

The study proposed an inventory policy for its products with the highest demand based on the analysis of the application of three planning techniques, which were the Silver Meal method, the minimum unit cost method and the EOQ. In addition, forecasting techniques were applied with a bimonthly historical data from the sales record that helped identify the products with the highest demand according to the ABC classification. The methodology carried out in a grocery store in Peru found that the demand behavior differed in each product; so, the standard deviation was analyzed. Then, the application of the three planning techniques was compared where a similarity in the frequency of orders and quantity between the Silver Meal and MCU was observed; on the other hand, the EOQ functioned as a preliminary step to identify a reorder point.

Compliance programs and systems of criminal or administrative liability are being increasingly adopted by different countries as measures meant to reduce the social cost of white collar criminality. However, the legal application of these measures does not always ponder correctly the impacts on common good, the levels of economic activity and the adequate functioning of markets of goods and services. Eventually, this situation can lead to undesired effects, such as the inefficiency of the criminal system, the reduction of economic activity or the arising of obstacles to competition. By taking these circumstances into account, in this paper we will utilize the Economic Analysis of Law to analyze the logic that inspires these legal institutes and the incentives they generate. Our objective is to delineate some parameters that allow legislators, judges, legal advisors and businessmen to eva...

Depression is regarded as a widespread mental condition that affects people of all ages. It has a negative impact on a variety of aspects of life, including mood, vigor, and interests in enjoying activities. In the most severe cases, depression can also result in suicide. creating the chance for collaboration between mental health professionals and the use of technical tools to enhance the assessment of the severity of depression to offer the patient with an ideal clinical diagnosis and an appropriate referral to begin treatment. The COVID-19 epidemic in Peru has decreased face-to-face interaction and quick access to medical professionals, making it more difficult for patients’ mental health to be identified or treated effectively, which results in the disease becoming chronic, psychological suffering, and high costs associated with specialized care. The implementation of a technology ...

The films can be obtained from renewable resources such as polysaccharides, proteins, and lipids. Potato starch is a polysaccharide found in abundance, low cost, biodegradable, edible, and can be obtained from agro-industrial waste. In the present study, biodegradable films were obtained from potato starch mixed with montmorillonite nanoclay (MMT) as crosslinking agent and glycerin as a plasticizer; and thus characterize properties such as: permeability to water vapor, solubility, thickness, functional groups by FTIR, analysis of the morphology by scanning electron microscopy (SEM), and mechanical properties. 9 mixtures combining different proportions of glycerol (1, 1.5 and 2 ml) with montmorillonite nanoclay (MMT) (0, 0.03 and 0.05 g) were prepared.

In 2013, there were 25.7 million stroke survivors and 6.5 million stroke-related deaths. Previous studies have indicated that approximately 40% of stroke survivors remain with functional impairments and need physical rehabilitation. However, many barriers could limit access to continuous physical rehabilitation for these patients, so devices that complement or assist in the rehabilitation process can be of great help. The quality, safety and efficacy of medical devices should be evaluated in randomized controlled trials (RCTs). However, the efficacy of many medical devices entering the market in the United States and the European Union (EU) has not been evaluated. Unproven post-stroke rehabilitation devices could be useless or even harmful to patients, thereby increasing healthcare costs. Previous studies have found that post-stroke rehabilitation devices without a rigorous evidence base...

En el Perú, la construcción de obras de ingeniería ha crecido significativamente, tanto en Lima como en provincias, con megaproyectos que superan los 3 mil millones de dólares. Sin embargo, es frecuente la aparición de daños en el concreto, los cuales suelen atribuirse únicamente a la calidad del material, sin considerar posibles fallas en el diseño estructural o en los procedimientos constructivos. Ante este escenario, los ingenieros deben estar preparados para enfrentar estos problemas mediante soluciones innovadoras que permitan reparar las estructuras de manera óptima, garantizando su funcionalidad y resistencia. En el país, no se cuenta con indicadores que reflejen el costo de reparación por fallas en proyectos, lo que genera un gasto significativo en correcciones. Entre las fallas más comunes en el concreto incluyen fisuras, cangrejeras, burbujas, juntas frías, deforma...

Correctly executing exercises during training is of vital importance to ensure adequate athletic performance. Sit-ups are among the most frequently performed exercises requiring proper evaluation. This exercise contributes to increasing abdomen strength, having better posture to reduce back problems, and improving overall physical condition and appearance, among other benefits. Existing methods for evaluating the correct execution of sit-ups are manual, subjective, and inefficient in terms of time, cost, and precision. Therefore, there is a need to have technological tools that measure and monitor core abdominal strength while simultaneously verifying, through image processing, the correct execution of the exercise. Since no solutions with these capabilities have been found in the literature, this work proposes a system that performs these functions using electromyographic (EMG) sensors,...

La estimación de funciones de vulnerabilidad se obtuvo mediante la estimación del costo medio y desviación estándar debido a daño sísmico producido por una cierta intensidad de evento sísmico, para una tipología estructural específica que caracterizan la incertidumbre del costo de daño desde el punto de vista probabilístico dado una intensidad sísmica que se asume aleatoria. El daño y su estimación se evaluaron para los elementos estructurales (columnas, vigas, losas aligeradas, placas etc.) y los no estructurales (tabiques, equipos, tuberías, instalaciones, vidrios, etc.). También se incluye los costos derivados de las pérdidas parciales o totales de funcionalidad del sistema estructural. Las curvas de vulnerabilidad son utilizadas como parte del análisis de riesgo sísmico que comprende las siguientes etapas: •Análisis del peligro sísmico •Análisis de la exposi...
