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...

There are many tools for developing applications in Java, but there are few alternatives for frameworks or specialized libraries for displaying charts in web environments. Although most of them are for desktop environments, the PrimeFaces and ChartistJSF libraries are an alternative for the web, but they are oriented to projects based on Java Server Faces. In this sense, many projects prefer to use a graphics library built-in JavaScript, which implies an additional learning curve and is more time-consuming in developing applications. Therefore, it is necessary to have a unique graphics display library or framework for Java applications in the web environment. Therefore, in this article, it is proposed to build a tool that helps develop graphical visualizations in Java web projects using the concepts of TagLibs and Webjars. The proposed tool is called EchartsTag, and it was built followin...

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.

Este artículo presenta un trabajo preliminar acerca de la implementación de un Scanlet para: (a) chequeo automático de generación de patrones relacionados con circuitos digitales basados en un modelo con interrupción en presencia de falla, (b) monitoreo y depuración in situ, (c) actualización de la arquitectura de un controlador lógico difuso, y (d) inyección de falla a nivel de pines usando Java API. Los puntos (a)-(c) son tareas de verificación. Como primera aproximación, el sistema STUD ha sido desarrollado empleando la arquitectura (incorporada) JTAG (Joint Test Action Group) y configurada por un CPLD para chequeo y operaciones de programación. Entretanto, las operaciones son ejecutadas por Scanlet, el cual puede ser corrido desde una página de Internet. Finalmente, un controlador lógico difuso, a manera de un núcleo JP, se usa como marca característica.

API REST is currently the most widely used application development approach worldwide, however, a large percentage of development is repetitive. Repetition in development generates waste of time and money. For this purpose, EasyRest is proposed, a project for automatic generation of API Rest based on Spring Framework. For the development of this proposal, a custom archetype was built in Apache Maven. In addition, the construction of templates based on Beetl is performed. The proposal generates a Rest backend project, which contains controllers, services and repositories. The results obtained with the proposal were able to significantly reduce the time required for the construction of API Rest, compared to a manual construction. As a conclusion, the EasyRest proposal allows the automatic creation of API's Rest in a minimum of development time, automating the development of backend project...

Importance of measuring the response time of web applications is transcendental for decisionmaking and/or corrections on the part of public officials involved in the departments of information systems and technologies. This research provides the conceptual framework for the development of a component J2EE (Java 2 Enterprise Edition) non-intrusive through Web Servlet filters and Interceptors of Spring Framework. It also uses the communication protocol TCP/IP for sending frames in JSON format (JavaScript Object Notation) and its subsequent reception for a stand-alone component for the record in a database. Finally, a hypothesis test between Log4j and Socket Simple technologies is performed, achieving an average record time of the plots approximately 0.05 seconds, and report that there are no statistical evidences to affirm that one is better and faster than the other.

Component identification is relevant in maintenance activities but can be hard in scenarios where the volume of source code is high and there is no architecture documentation. This work presents a technique for finding concepts as candidates of architectural components. The technique is based in the frequency of terms that follows naming patterns that are proposed in this work. Projects from Eclipse and Apache, were used for evaluating the technique. The results show terms which match with some popular component types and domain concepts of the software in treatment. The technique has used source code without any architectural documentation showing that could be applied in emergent architectures.

This work aims at discovering topics in a text corpus and classifying the most relevant terms for each of the discovered topics. The process was performed in four steps: first, document extraction and data processing; second, labeling and training of the data; third, labeling of the unseen data; and fourth, evaluation of the model performance. For processing, a total of 10,322 "curriculum" documents related to data science were collected from the web during 2018-2022. The latent dirichlet allocation (LDA) model was used for the analysis and structure of the subjects. After processing, 12 themes were generated, which allowed ranking the most relevant terms to identify the skills of each of the candidates. This work concludes that candidates interested in data science must have skills in the following topics: first, they must be technical, they must have mastery of structured query languag...
