Hiring processes are intended to recruit and retain ideal candidates; those who would generate competitive value in an organization. In an increasingly global context, the challenge is often costly, inefficient, and complex. Even though artificial intelligence already solves specific tasks with greater speed, precision, and efficiency in various fields, and in different companies, in the area of human resources the desirability of the use of data science continues to be debated. By reviewing cases and research, in which the integration of artificial intelligence applications in the selection processes was tested, measuring and socializing impacts, I contribute to the current discussion aimed at overcoming the mistrust that exists by default, and that is associated with the ethical challenges and risks t assumed to solve a human problem through technology. I conclude that it is possible t...

This paper focuses on sustainable public procurements that seek to minimize negative environmental impacts and improve positive social impacts, which require significant changes within the market reality of a country. In the case of Peru, legislation establishes the requirement that sustainable criteria be integrated into public procurement suited to the needs for the procurement of goods and services. In this way, the problem that this study seeks to resolve relies on technical non-observance to verify compliance with current regulations in force within the supplier selection process that consider sustainability criteria. Therefore, the application of the Hierarchy Analytic Process (AHP) is suggested as a heuristic solution alternative. This selection model makes it possible to improve the administrative process by increasing objectivity and reducing cognitive bias. To demonstrate this,...

In any industrial operation, a major problem in the maintenance of tools, equipment and machinery is that of minimizing wear or recovering worn parts, the cost of which is less than the cost of changing them, for which it is important to recognize the problem and the way to recover them, which generally involves the application of a metallic coating by welding and machining for its finishing. But this is not everything, the most important thing is to know how and with what material to reprocess the piece; For this, it is necessary to know how to select the appropriate type of coating and its application process. The purpose of this work is to select the most suitable coating for the base metal of the worn part.

Este trabajo se enfoca en las compras públicas sostenibles que buscan aminorar impactos ambientales negativos y mejorar los impactos sociales positivos, las cuales, para funcionar, requieren de cambios significativos dentro de la realidad del mercado de un país. En el caso peruano, la legislación establece la obligación de que los criterios sostenibles integren las compras del Estado homologadas a las necesidades para la adjudicación de bienes y servicios. De esta forma, la problemática que pretende resolver esta investigación reside en la inobservancia técnica para verificar el cumplimiento de la reglamentación vigente en el procedimiento de selección de proveedores que consideren los criterios de sostenibilidad, para ello, sugerimos la aplicación del proceso analítico jerárquico (AHP) como alternativa heurística de solución. Este modelo de selección permite mejorar el p...

Image restoration consists in recovering a high quality image estimate based only on observations. This is considered an ill-posed inverse problem, which implies non-unique unstable solutions. Regularization methods allow the introduction of constraints in such problems and assure a stable and unique solution. One of these methods is Total Variation, which has been broadly applied in signal processing tasks such as image denoising, image deconvolution, and image inpainting for multiple noise scenarios. Total Variation features a regularization parameter which defines the solution regularization impact, a crucial step towards its high quality level. Therefore, an optimal selection of the regularization parameter is required. Furthermore, while the classic Total Variation applies its constraint to the entire image, there are multiple scenarios in which this approach is not the most adequat...

Teleosemantic is the theory that proposes an explanation of mental representation on the basis of the Darwinian theory of biological function. Although Darwin explains biological traits for both historical and adaptationist causes, Papineau and other proponents of teleosemantic rely only on the adaptationist dimension of the theory to account for the identity of the biological trait. This is shown in the teleosemantic response to the possibility that an exact duplicate of a human arose from non-evolutionary causes (the swampman). Clarifying the question about the homological nature of the trait identity is central to addressing the swampman argument. This argument has been renewed in the form of an empirical counterexample: the existence of functional tetrachromacy, a condition that would constitute a real case of mental representation that is not the result of a selection process. I wil...

Metal mining is one of the economic pillars of the Peruvian economy. Peru is the main producer of gold, zinc, lead, and tin in Latin America and the second largest producer of copper, silver, and zinc worldwide. Despite its economic importance, mining has also left a plethora of Mining Environmental Liabilities (MEL) whose inadequate waste management represents a risk for both the environment and human health and is a common trigger of social problems. The Cajamarca región is the second región in Peru in terms of the number of MEL sites with the majority of them located in the Hualgayoc district. The goal of the PhD project is the assessment of the environmental impact of MEL in the Peruvian Andes using as an example two post-mining sites in the Hualgayoc district. This evaluation includes the study of soils and native plant species in terms of their metal accumulation potential and th...

A major problem in water companies is to detect leaks in underground pipes as water is a limited source. For many years, acoustics techniques have been used to reduce this problem enhancing leak detection positioning estimation. The correlation of leak noise signals is one of these techniques. Moreover, using the time difference of the arrival of the leak noise at the sensors, and knowledge of the speed at which the noise propagates in the pipe, the distance of the leak from one of the sensor positions can be estimated. This paper describes the importance of the bandwidth selection in the estimation of the time delay. Experimental cases from a test rig in Brazil are shown to support.

In the construction sector, the selection of personnel for the technical office faces challenges such as the lack of structure and subjectivity in the evaluation criteria, which makes it difficult to quickly identify the most suitable candidates. This article proposes an optimized procedure to address this problem through the use of the AHP multicriteria method and Expert Choice software. The process involves applying AHP to establish priorities and evaluate candidates based on previously defined objective criteria. Through interviews and surveys, deficiencies in the traditional approach were identified, such as the lack of planning and the reliance on subjective judgments. The proposal demonstrates how the application of AHP reduces the evaluation time by 70%, improving transparency, traceability, and reliability of the process, contributing to the formation of technical teams more alig...

Nowadays, bottling industries perform inefficient maintenance and transportation sub-processes, such as: boxing, unpacking, and selecting. These functions are performed by workers during long hours, which causes delays in the general production process, risks in the safety of personnel and integrity of the bottles, a tendency to a greater number of errors and especially, severe medical problems caused in the long term. In view of the advantages of industrial automation, it is known that it makes use of the union of engineering knowledge to facilitate procedures and guarantee reliability. This is the case of industrial robots that are increasingly required to optimize numerous systematic strategies in many fields; however, it is complex to develop an autonomous artifact that adapts to variable changes in different environments. Despite the existence of interesting projects for grippers or...
