This article develops a robust platform for remote process management.JAVA language is used as a programming language at three levels of development: Control Servers, Web Server and Web Clients. The interaction with the control servers will be through the serial port and/or parallel port depending on the requirement. Thus we can interact with any specialized control device: A microcontroller, a PLC (Programmable Logic Controller), a DSP (Digital Signal Processor) or sophisticated sensors that send data through the aforementioned ports, theLocal network of Control servers ensure the reliability and proper functioning of our processes.The exit door to the Internet will be the "Web Servers", which serve clients; Such a client does not have direct access to the system, until it has verified its privileges. The information thatjourney through the Web is encrypted. Using a microcontroller we w...

With the evolution of browsers and the implementation of new Web standards (HTML5), new tools became available that have enabled us to create more complex web applications with better user experiences. Over time, these types of applications have proven useful, but deteriorate the user experience as extended lengths of time are used load the data on each page. For this same reason, it is proven that there is a need for interaction from the server to the generation page with the hybrid applications. One such technique was to allow the use (creation and modification) of graphical user interface elements, both in the client just like the server, which is why these applications are called isomorphic. This article shows the process that was undertaken to arrive at the concept of isomorphic applications, which describes the characteristics that must have an isomorphic implementation and, finall...

This paper describes a cooperative thread scheduling mechanism, which can be used effectively on real-time java virtual machines. This scheduler is implemented using a heap-based priority queue which allows for O(log N) processing time. Since this scheduler is strictly cooperative, thread coordination is performed without the requirement of formal java thread synchronization. Though similar outcomes can be achieved through program design, this abstraction allows developers to focus on their application.

El principal problema que tiene la empresa minera ABC durante el proceso de compra de mineral aurífero a mineros artesanales es no tener la información precisa en tiempo real, no solo de los lotes de mineral que compran, sino también de los lotes rechazados. En este proceso de acopio, se validan ciertas características del material mineral que son importantes para garantizar un producto final de calidad y así obtener mayores ganancias. El desconocimiento y demora de dicha información, perjudica al área de planta ya que no se puede realizar una buena planificación de la producción. El siguiente trabajo de suficiencia profesional presenta una aplicación web para la compañía minera, que se diseñó y desarrolló como solución al problema de manejo de información del proceso de acopio y compra de mineral aurífero. La aplicación web fue desarrollada en lenguaje Java y cuenta c...

The purpose of this article is to expand the taxonomy of the most frequent ethical misconducts currently found in scientific publications. We present examples of fraud in contrast to an ethical conduct in research and publications arising from research. Then, we show the taxonomy in different stages: before, during and after the publication. Before the publication, the following ethical misconducts were found: conflicts of interest not declared by the authors, undeserved or insufficient authorship, salami slicing, plagiarism, self-plagiarism, fabrication, manipulation or impossibility of data replication, and parallel submission of articles. During the process of publication: conflicts of interest in peer review, false peer reviewers, theft of the manuscript by peer reviewers, content mishandling and undeserved authorship following peer review. After the publication: alteration of the im...

In Peru, grasslands monitoring is essential to support public policies related to the identification, recovery and management of livestock systems. In this study, therefore, we evaluated the spatial dynamics of grasslands in Pomacochas and Ventilla micro-watersheds (Amazonas, NW Peru). To do this, we used Landsat 5, 7 and 8 images and vegetation indices (normalized difference vegetation index (NDVI), enhanced vegetation index (EVI) and soil adjusted vegetation index (SAVI). The data were processed in Google Earth Engine (GEE) platform for 1990, 2000, 2010 and 2020 through random forest (RF) classification reaching accuracies above 85%. The application of RF in GEE allowed surface mapping of grasslands with pressures higher than 85%. Interestingly, our results reported the increase of grasslands in both Pomacochas (from 2457.03 ha to 3659.37 ha) and Ventilla (from 1932.38 ha to 4056.26 ha...

This proposal aims to improve the efficiency of the packaging process of a company specialized in seasonings and ground foods through the application of the Lean Manufacturing approach. To carry out this study, data was collected from a Peruvian company, which was evaluated using a simulated validation model in the Arena version 16.1 program. This process included the participation of experts in the relevant areas, ensuring significant results for potential implementation. The results obtained indicated a significant reduction from 7.5% to 0.08% in the generation of defective products per production. In addition, production times were reduced in tasks related to the packaging line of one of its products. These findings allowed us to conclude that the simulation model is highly replicable in various production lines of the company. In comparison with other related studies, it stands out t...

In the present study, the control of the pyrolysis temperature was carried out in a gasification process of eucalyptus wood, its prediction is made based on the operating parameters of the reactor to ensure the obtaining of a synthesis gas with the required quality. The results obtained from the mathematical modeling for the prediction of the pyrolysis temperature with the use of artificial intelligence techniques and the development of artificial neural networks are shown, with experimental data of the process. For this reason, an experimental statistical design of type 3n was implemented, with two additional replications, by means of which the training of an artificial neural network capable of predicting the pyrolysis temperature in a downdraft type gasifier with cogeneration was carried out. The prediction of the pyrolysis temperature has an error of 4.6 oC and an adjustment of 93.71...

This study investigates the integration of Total Productive Maintenance (TPM) and Lean methodologies within the Peruvian agricultural sector, focusing on asparagus packing operations. A model was developed to address critical challenges of low productivity, employing autonomous and preventive maintenance strategies to reduce unplanned downtime and the implementation of Standardized Work to eliminate inefficiencies. A pilot project was implemented using a sample of 72.98 kg of processed asparagus, using processing times from each activity as input data for the model’s validation. The Kolmogorov-Smirnov and Chi-square statistical tests were applied to establish time distributions. The proposed model, validated through Arena software, demonstrated a 21% increase in packing productivity, a 36 kg/man-hour improvement in labor productivity, and a 26.35% enhancement in machinery availability....

This study evaluates the application of Total Productive Maintenance (TPM) and Lean methodologies in the Peruvian agricultural sector, focusing on asparagus packing operations. To this end, it develops an innovative model with the objective of increasing the productivity of asparagus packing, one of the main problems of the Peruvian agricultural industry. Through the application of an autonomous and preventive maintenance strategy, it seeks to eliminate untimely stops in the asparagus processing line. Meanwhile, with the implementation of standardized work, the aim is to eliminate activities that do not add value and downtime. A pilot project was implemented with a sample of 72.98 kg of processed asparagus, using the processing times of each activity as input data for the validation model, using Kolmogorov- Smirnov and Chi-square statistical tests to define the distributions of the times...
