Ítem Acceso Abierto Algoritmos Murciélago Binarios para el problema de cobertura de conjuntos [Binary bat algorithms for the set covering problem](Institute of Electrical and Electronics Engineers Inc., 2015) Crawford, B.; Soto, R.; Olea C.; Johnson, F.; Paredes, F.In the present paper, we resolve the Set Covering Problem using the recently presented meta-heuristic named Binary Bat Algorithm. We use two variations of this algorithm. The Binary Bat Algorithm algorithm was created observing how the bats evade obstacles and find preys to eat, the use of echo-localization is how they do it. We made some changes using two different transfer and two discretization techniques to solve the problem. © 2015 AISTI.Ítem Acceso Abierto An open coworking space to allow engineering students to develop innovative competences: UTEC GARAGE(Institute of Electrical and Electronics Engineers Inc., 2017) Murray, V.; Bejarano, A.; Matsuno, C.Interactions between industry and academia are seen as one of the key elements of the quality of higher education and a key element of the system of innovation of the nations. However, there is a widely noted gap between industry needs and the education that new engineers receive. This manuscript presents an open coworking space implemented by the Universidad de Ingenieria y Tecnologia equipped with electrical, mechanical and industrial tools, to allow students, faculty and industry's engineers not only to build engineering projects or products that solve real problems, but also to fix and adapt personal technical products by applying and developing theirs innovative skills. We have called it the 'UTEC GARAGE' and this space is transforming every time according with the different projects developed to assure the learning and collaboration between industry -Academia - society. We are in the second version of the implementation. Started in 2014, the UTEC GARAGE is always open to the university community with a total of more than 250 projects developed in only 4 semesters, including 1 patent and 4 patent applications. We expect to have a full use of the UTEC GARAGE in the next semester to get up to 500 students, 170 engineering projects, per semester. We have started talking to close universities to replicate this model in their campuses to create a GARAGE network to provide more collaboration in engineering education and projects. © 2016 IEEE.Ítem Acceso Abierto Estrategias de enumeración para resolver problemas de satisfacción de restricciones: evaluación de desempeño [Enumeration strategies to solve constraint satisfaction problems: performance evaluation](Institute of Electrical and Electronics Engineers Inc., 2015) Soto, R.; Crawford, B.; Olivares R.; Herrera R.; Johnson, F.; Paredes, F.In constraint programming, efficiency in the resolution process can be affected by the order in which the variables of the problem and the domain values are selected. This activity is known as enumeration. At the beginning, it is difficult to determine the best choice variable-value pair that can generate potential solutions for constraint satisfaction problems. In this paper, we present an evaluation of different enumeration strategies, based on performance exhibited in a set indicators. These strategies solve different instances of constraint problems satisfactions. The results show that it is feasible to solve constraint satisfaction with at least one strategy enumeration. © 2015 AISTI.Ítem Acceso Abierto Optimización por colonia de gatos del problema de cobertura de conjuntos [Binary cat swarm optimization for the set covering problem](Institute of Electrical and Electronics Engineers Inc., 2015) Crawford, B.; Soto, R.; Berrios, N.; Johnson, F.; Paredes, F.The set covering problem belongs to the combinatorial optimization problems, whose complexity is exponential theoretically established as NP-complex problems. Consists in finding a subset of columns in a matrix of zeros and ones such that cover all rows of the matrix at minimal cost. The solution to this problem is presented using, for first time, the binary cat swarm optimization algorithm. This metaheuristic is based on the cat's behavior, where cats have curiosity by objects in motion and have a great hunting ability. Cats have two modes of behavior: seeking mode and tracing mode. The algorithm is tested on 65 instances, which are compared in a result table including a column with the relative percentage deviation. © 2015 AISTI.Ítem Acceso Abierto Problema del conjunto de cobertura resuelto mediante el algoritmo Binario de Optimización basado en Enseñanza-Aprendizaje [The set covering problem solved by the Binary Teaching-Learning-based Optimization algorithm](Institute of Electrical and Electronics Engineers Inc., 2015) Crawford, B.; Soto, R.; Leiva, F.A.; Johnson, F.; Paredes, F.The Set Covering Problem (SCP) is a representation of a kind of combinatorial optimization problem which has been applied in several problems in the real world. In this work is used the binary version of Teaching-Learning-Based Optimization algorithm (TLBO), which works with two phases known as teacher and learner phases in this way emulates the behaviour into a classroom, besides this problem is solved with eight different transfer functions and five discretization methods all of them altogether to solve The Set Covering Problem from the OR-Library. © 2015 AISTI.Ítem Acceso Abierto Representaciones del género femenino en medios de comunicación digitales vía análisis crítico del discurso: un caso de estudio [Female gender representations in digital mass media via discourse analysis: a case study](Institute of Electrical and Electronics Engineers Inc., 2015) Niklander, S.; Soto, R.; Crawford, B.The goal of this work is to reveal the discursive strategies that employ the digital platform of a Chilean mass media to represent the female gender and the corresponding people interaction on social networks with respect to the news. This is important because if we can detect the existence of male hegemony, we could conclude that it is a prevailing ideology and thus corroborate the existence of a patriarchal order in the national press. We take as a starting point that mass media constitute a privileged access platform, because through language they spread a particular world vision, even though the press - as publicly representation - intend to accommodate a wide and heterogeneous set of speeches. The mass media, as active agents in social processes, target imagined, massive, and diverse audiences, because through its discourse, they present fragments and perspectives of the 'reality' with which hide, describe, make visible, ignore or reinforce constructions and ideologies. When analyzing the modes of representation of the female gender, we observe how they refer to the women, generating an important and motivating challenge that will allow us to detect and describe how the subordination of the female gender is manifested in a particular social time. © 2015 AISTI.Ítem Acceso Abierto Reuniones efectivas: con la mirada en las emociones y conversaciones para potenciar el capital de las organizaciones [Effective meetings: With a focus on the emotions and the conversations to improve the capital in the organizations ](Institute of Electrical and Electronics Engineers Inc., 2015) Olguin E.; Crawford, B.; Soto, R.If the meetings within the organizations properly fulfill their purposes would be of a high strategic value. However, they are often considered as inefficient and ineffective. The organizations invest time and resources in improving their productions and organizational processes but not in optimizing their meetings. When they do so, usually they do not get the results expected. At first glance, it seems an issue of an easy solution but it is not, because it is connected to the complexity of human beings. The traditional conception associates a meeting with a time or physical space where issues that are in a list of topics are addressed. Through the proposal that we have successfully worked in the organizations we outline that the meetings are rites of conversational networks and organizational processes. This understanding opens a wide range of possibilities and opportunities of optimization. © 2015 AISTI.
