Esta investigación se centra en la implementación de la reingeniería del proceso de medición de los Stock Keeping Unit (SKU) importados por un centro de distribución de una empresa especializada en la venta de productos para la mejora del hogar y materiales de construcción. Para identificar los factores que influyen en el proceso y optimizarlo, se realizó un estudio de tiempos y movimientos del proceso utilizando la herramienta conocida como diagrama de espagueti. Como resultado, se incrementó la productividad y disminuyeron los tiempos muertos, lo que permitió medir en menos tiempo el universo de SKU. El estudio también condujo a la configuración del sistema utilizando datos correctos, lo que facilitó la operación dentro del almacén.

Our location in the world makes us a country with a high seismic risk. Taking into account that the information produced during a seismic event is of vital importance for the study carried out by seismology, it is necessary to use the appropriate type of instrumentation to record these data. Currently, electronics provides the necessary technology for the study of phenomena of this type. The design and construction of a Digital Accelerograph will allow us to carry out a detailed study of a seismic movement and the effect caused on the structure of buildings. Finally, we can say that the construction of an instrument of this type at a low cost will allow repowering and increasing the CISMID accelerographic network and, in general, improve the knowledge of seismic phenomena at the national level.

A Schlumberger resistivity record was made over an area of 50 hectares. A new field of processes based on the analytical signal response of the resistivity data was tested in the presence of disturbed phosphate deposits. Geology models were successively obtained from a peak model of the 2D resistivity data. The optimization of the imaging process was based on the optimization of surface tools. The descending analytical extension of the modeled surface over a depth of 30 meters was used for optimization of the modeling. The analytical processes found were consistently useful. The optimization of the phosphate reserve was improved and better constructed.

Nowadays, the construction industry has become the main and great engine of the global economic recovery after the effects of covid-19, generating around 10.7 trillion dollars worldwide, and it is residential construction, specifically, the one in charge of driving growth in the short term, thanks to the constant demand for residential spaces. In this sense, various challenges such as new technologies, the complexity of projects, and a growing competitive environment, force the main contractor to subcontract between 80 and 90% of the activities, thus evidencing that subcontracting is an applied and necessary process in every construction project, and making subcontractors the backbone of the procurement strategy. However, one of the main risks of subcontracting is the inadequate selection of the construction subcontractor, which is often based solely on the criteria of selecting the know...

This study evaluates the implementation of the digital platform Safety Culture (iAuditor) to optimize quality assurance and control (QA/QC) processes in multifamily construction projects, reducing time requirements and errors associated with traditional methods. Using a quasi-experimental approach, manual processes (pen-and-paper) were compared with real-time digital workflows, demonstrating that the tool eliminates redundant steps such as transcriptions and scanning, saving up to 60 minutes per inspection. Results showed significant improvements in efficiency, accuracy, and data accessibility, though challenges remain in externally coordinated activities. The proposed solution included staff training and customized digital form templates, highlighting its potential as a replicable model for the construction industry.

The objective of this work, is to make an analysis of the data (dates) or information, like a right protected by the cybernetic society. All society is constructed with uses, customs and values which are importants assets to their citizens, so they must protect them. These, rights, assets are not absolute, and are changing with the course of time. Some of them because of their importance and transcendence are constituted in main paradigms of the corresponding society. From half-full of the last century, a new form to process the information (computers) has been generated, with a special language (binary), that allows the data processing (systems) in a complex and different form from the traditional one. To these high technologies, communicational triggers were added (internet), that changed the value of the information at world-wide level, and constituted them in its main paradigm
