Abstract

It is important for small growing textile companies to make key decisions based on accurate and reliable information about the present production process and how future changes could affect them. Using traditional mathematical methods it is not possible to accurately and reliably reflect the real stochastic behaviour of processes and activities carried out in this industry. There are, however, information technologies such as the computer simulation technique that allow such information to be obtained taking this behaviour into account.he research carried out a simulation study of the garment making process of a small textile company in order to propose a better distribution of resources by experimenting with a simulation model of the process, In addition, some of the quantitative information obtained with this technique is presented. The results obtained show that making changes in assigning tasks and resources reduces the production time of a batch of 100 units in one hour and reduces approximately 30 minutes the average time that a unit remains in the system. All the information was obtained by means of a simulation model verified and validated without the need to experience such changes with the real system.

Abstract

GitHub is a platform that provides hosting for software development version control using Git. It features an application programming interface to allow the software to interact with the platform. The enormous quantity of information Hosted in GitHub may be useful to make studies about the current presence of development tools in the open-source software development community. However, the search engine has restrictions that make it impossible to issue complex queries to the platform. In this report, it is described as an object-oriented and extensible solution, named QuantityEr, to obtain the number of search results of complex queries to GitHub by using the inclusion-exclusion principle. The mathematical definitions, as well as related concepts, are presented. The mathematical model is discussed. The application of general design and used development tools are presented. Also, the results of the execution examples are showed. It is concluded that the treated problem has been solved although more work may be done to improve the solution.

Abstract

The implementation of any software development process involves the consumption of critical resources. Software engineers cannot experiment with different development processes before starting them in real projects, due to the time that would entail and the amount of elements that are involved, so it is vital to have tools that allow the pre-visualization of the results of executing the software development process and how the environmental variables affect it, thus being able to anticipate under what conditions the software development process will be deployed. This paper presents the modelling and simulation of a software development process using System Dynamics (SD), which allows the graphical representation of the elements intervening in the software process, and the incorporation of as many relevant elements as possible. As a software costs estimation reference, the COCOMO estimation model was used; which beyond being reliable has a theoretical-practical foundation. As an ideal, and real, software process system, the Craig Larman Software Process model was chosen, also known as the Larman Method. The simulation model developed here, allows one to make some initial estimation of the software process and its elements’ behavior in the course of the simulation time. This is possible thanks to the observation and study of the system’s state variables, empowering one to discern about the effect of changes in the parameters on the general process, hence, carrying out relevant and interesting scenario studies. This model becomes a tool for supporting Software Project Management teams and enterprises whose business care on Technological Projects Management.

Abstract

The fingerprint orientation field is a widely used feature for developing indexing strategies. Such feature brings stability and decreases the response times during the identification process. The use of attribute relational graphs and dynamic masks can exploit the features provided by the partitioning scheme. The penetration index and the error rate for each of the proposed strategies were determined. To verify the results obtained were used the databases provided by the Fingerprint Verification Competition. Both search schemes reveal the facilities offered by the orientation field for guiding the searching process; reducing the number of comparisons in 53.24%; proving its stability against different fingerprint image qualities. Based on the results, it was proven that the adoption of such indexing strategies will reduce the response time in the identification module proposed by the Identification and Digital Security Center at the University of Informatics Sciences.

Abstract

Nowadays, there is a growing use of information technologies, contributing to the development of organizations. The difference between the success and failure of the use of information technologies does not depend much on the characteristics of this, Rather the ability of managers to use it strategically. Therefore, models of Information Technology Service Management have been developed so that organizations can offer services effectively and with a higher level of quality. These models see several aspects, one of which is configuration and change management. Changes will occur at any time so we must be prepared. A comparison of three IT service management models was made focusing on configuration management. IT Service Management models can be combined using the necessary processes and adapting them to the project.

Abstract

Nowadays, some of the most popular tools for parallel programming are Message Passing Interface (MPI) and Open Multi-Processing (OpenMP). It is of interest to compare these tools in solving the same kind of problems, because of the use of different approaches to inter-task communication. This work attempts to contribute to this goal by running trials in a centralized shared memory architecture in the case of problems with an entirely parallel solution. The selected case study was the parallel computation of Mandelbrot set. Trials were conducted for different iteration limits, processors amount, and C++ implementation variants. The results show better performance in the case of OpenMP.

Abstract

The resolution of triangular systems is a computational nucleus widely used in various scientific applications. This research performs the implementation and comparison of several parallel algorithms against an efficient sequential algorithm for solving triangular systems. The algorithms are distinguished by the way of partitioning the matrix and the allocation to the processors. The analysis of the behavior of the algorithms is performed in the solution of systems of linear superior triangular equations in a cluster of computers. For this, the arithmetic time, communication time, speed-up, and maximum efficiency metrics are taken into account. Experiments were performed for each algorithm with different matrix sizes on various processors. The algorithm with the best results was the one that blocks the rows of the matrix and applies a cyclical distribution in the cluster.

Abstract

This article presents the possibility of working on software development using not only agile methodologies for processes but also the use of Design Thinking for the planning of the Software Test Plan. Since during the software management process there is the difficulty of understanding the software, for one of the stages of the software management, in this case, the planning of the software tests, the tester needs to know what the user requires, due to Because the software product is intangible and difficult to measure, the tester must listen to the end-user and perform the tests according to the requirements requested. To improve the process of understanding what the user really requires, its pillars are used as empathy, collaboration, and prototyping for a better interpretation, which will allow obtaining an assertive attitude to the tester. On the other hand, we have to carry out the software test plan, based on this a study was carried out on the possibility of using Design Thinking to help the software test planning process.

Abstract

The University Student Federation in Cuba carries out an important number of processes that require reducing the processing time of the information that is generated, standardizing the documentation provided by the different areas in relation to the organization, and increasing the persistence of the data. This report shows the results of the implementation of the Comprehensive Student Assessment System tool. This is a computer application that ensures the quality of the student evaluation process. It focuses mainly on the process of comprehensiveness and characterization of students, recording the trajectory of each of them in a digital file through evidence. The system was developed on the Django framework, using Python as the programming language, using PostgreSQL as the database server. To guide the entire development process of the system, the AUP-UCI methodology was used, adjusting to the technological sovereignty for which Cuba advocates. It has ten subsystems that are integrated with each other and allow the correct operation, integrity, and persistence of the data that is entered and processed. As part of the investigation, the tool is validated from different tests to the system which allowed to test the correct operation of the system and the satisfactory results of the same gave validity to the present investigation, this being the basis for the system to be able to promote student processes that take place in all universities or headquarters in the country.

Abstract

When facing evaluations in the Teleinformatic subject, it is common for students to present difficulties demonstrating the fulfillment of the objectives. Frequent evaluations become an effective tool in the hands of teachers to promote the consolidation of knowledge and the development of skills. However, the teaching load and the tendency towards finalism in students cause little systematization in the study of the subject and therefore poor results in frequent evaluations. Taking into account the existing technological development and the constant linkage of students to ICT, a guide for the design and application of an evaluative instrument for frequent evaluation combined with a computer system is proposed in this work, thus involving novelty and motivation in students through gamification techniques.
