Contribution: The brix degree meter has the purpose of using it in the field and in the laboratory to collect the information corresponding to this parameter (brix degrees) to sample the crops of vegetables, fruit trees and mainly grapes that are held in the vineyards of the Technological University of North of Aguascalientes, being able to monitor the ripeness of the grapes as well as the grapevines of these vineyards through data collection and analysis, and even decide based on the results of brix grades taken and analyzed by the meter to harvest this product at the best time. Objectives: To develop a brix degree meter for both didactic and professional use, which allows us to sample this parameter in the field in the plants and mainly in the fruit of the vineyards of the Technological University of the North of Aguascalientes and in the surrounding region of the same for monitor the degree of maturity of the crops and thus determine the best seasonality of harvesting the grapes based on data analysis trying to obtain the best product for the production of table wines. Methodology: The light refraction method and also for conductivity should be considered to develop the device to measure the brix degrees, since they are a simple and commonly used methods, the electronic processing of the sample in the same device will be done a comparison of parameters according to the scale determined for the different types of grapes that you want to monitor, the data of a number of samples will be stored and the necessary statistical calculations will be made that will yield the result and will suggest in based on these the ideal time of harvest, said data may be downloaded in a database for its history and laboratory monitoring.

This research is the result of 3 investigations carried out in three of the main Industrial Parks of the state of Aguascalientes, Mexico. The industrial parks on which this research is based are the San Francisco de los Romo Park, the Industrial Park of the Aguascalientes Valley, known as PIVA and the Santa Clara Park. The purpose of this paper is to investigate which are the Management Indicators used by the Automotive companies in the Industrial Park of San Francisco de los Romo. The most important aspects of the companies they incur in implementing the management indicators of the areas of: - Administration. - Human Resources. - Production. - Logistics. - Maintenance
