En esta región costera, el agua subterránea abastece el 100 % de demanda agrícola. El acuífero se viene explotando por más 100 años, a tasas de extracción cada vez mayores, lo que ha generado un desbalance hídrico con el consiguiente proceso de contaminación por intrusión marina. En esta investigación se busca identificar la conceptualización hidrogeológica del sistema y su efecto en el manejo sostenible del agua subterránea. Esto permitirá establecer lineamientos para el manejo sostenible del agua subterránea, planteando medidas de tipo estructural y no estructural; las primeras, orientadas a afianzar artificialmente los recursos hídricos de recarga al acuífero; y las segundas, a establecer un plan de gestión y reordenamiento de extracciones, para precisar el volumen de extracción y las medidas estructurales a adoptar. Adicionalmente se debe incorporar criterios de educación ambiental, sensibilización y divulgación, orientados a la conservación y preservación del acuífero.","PeriodicalId":41362,"journal":{"name":"Ingenieria UC","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42900882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

En cuanto en el número de granos por vaina y productividad de agua (WP) no se encontró diferencia estadística entre los tratamientos. Él déficit hídrico con el 60 % de ETc afectó todas las variables de crecimiento y rendimiento, mientras que el déficit hídrico del 80 % de ETc no afectó los órganos reproductivos ni vegetativos con un rendimiento menor que el T1, pero con diferencias mínimas, en este sentido se concluye que el T2 se puede emplear satisfactoriamente ya que se obtuvo mejor productividad del agua con respecto al T1 y T3.","PeriodicalId":41362,"journal":{"name":"Ingenieria UC","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49337126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to determine the optimal option, the hub location is compared by several parameters. Such values as passenger traffic, existing routes of urban public transport, priority directions of passenger traffic, and capital investments in construction are selected as optimization parameters. To determine the values of passenger traffic, an analysis of the existing passenger traffic was performed, with its allocation by capacity and routing. The unevenness of passenger traffic by days of the week and periods of the day is determined, the minimum and maximum values of passenger traffic are revealed, as well as its fluctuations over the considered periods. The construction of public urban transport routes allowed to identify the busiest routes and the availability of transport for different variants of the transport interchange hub location. The options of organizing the possible arrival/departure of urban public transport to/from the transport interchange hub are considered. Using the obtained data, a SWOT analysis was performed to determine the strengths and weaknesses of each hub placement option and the optimal variant was selected.","PeriodicalId":41362,"journal":{"name":"Ingenieria UC","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42025357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This tool is based on an integrated mathematical model that considers the ambient conditions, the thermal loads of the building, the pre-sizing data of each of the components of the system and the simultaneous interaction among them, to conduct a realistic, simple, and precise analysis. A demonstrative simulation example was performed. During the month of July, with a solar opening area of 704 m2 and a tank of 35200 L, a total amount of 47,5 MWh of cooling energy was obtained, with a reduced contribution of the auxiliary system (5,6 MWh) and a minimum number of solar collector system deactivation hours (0,7 %). The daily COP of the absorption machine remained above 0,69.

The suggested model can be implemented in a system for organizing the safety of rolling stock operation. The relevance of improving safety is particularly acute when operating high-tech rolling stock with a high complexity of control algorithms. The objetive is the analysis and development of solutions to improve operational efficiency using a model that provides solutions to the problems of choosing optimal and safe operating modes from the point of view of implementing rolling stock management processes. Reducing the number of violations during the operation of rolling stock can be realized with the active use of a risk-based model that takes into account the possibility of predicting factors that affect the occurrence of risks. In this regard, the issues related to the implementation of risk management in operational locomotive depots are considered. The most rational approach to the implementation of risk management for a variety of uncontrolled factors that have a significant impact on the safety and accident-free operation is given. A model for solving multi-criteria problems is suggested as one of the options for choosing the safe operation of rolling stock.","PeriodicalId":41362,"journal":{"name":"Ingenieria UC","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46058056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
