Intelligent control systems are dramatically changing domestic technology. The so-called smart homes are environments where technological tools provide convenience and comfort to residents and contribute to the reduction of energy consumption. The term smart is used due to high communication capability between devices and the use of algorithms that analyze the profile of each resident in order to optimize the use of resources and provide custom routines. The aim of this study is to verify the effectiveness of a control system that makes use of fuzzy logic to control the brightness level to be applied in accordance with the amount of light captured in the environment. An application which enables the automation of the lighting system has been created. The results of the experiments show that the system is efficient and the fuzzy logic allows the brightness control properly, reducing or increasing the incidence of illumination without abrupt changes.

This article aims to propose a recognition model of traffic lights which is based on biological concepts of artificial intelligence, specifically visual attention, image processing, and fuzzy. The proposed model uses information from the color histogram of the detected area as input to the fuzzy machine to classify a scene as having a red or green light. Experimental results obtained in the daytime and nighttime periods reveal the efficiency of the proposed model.

This paper presents an application that implements three load balancers using a Software Defined Network (SDN). The application was developed for the Ryu controller. First, the principles of three queueing algorithms are presented; the selected algorithms are: FIFO, Round Robin and Deficit Round Robin. Then, the main aspects of the design and implementation of load balancing modules based on each of the aforementioned algorithms are outlined. The application is able to assign a client request to a server based on the criteria associated to a given queuing algorithm. Additionally, the tests that were carried out with the application using both a virtual SDN implemented with Mininet and a physical SDN using an OpenFlow switch are discussed. Finally, the results of the tests on the physical SDN that focused on proofing the functionality and estimating the response time of the application are included.

This research paper defines challenges in the process of managing activities involved in the thesis subject, which is part of the bachelor curriculum of the Systems engineering program at the Catholic University of Colombia. Enterprise architecture (EA) is applied through TOGAF framework to propose a new process model to improve the current process model. The business domain defined in TOGAF is considered to analyze and define the current and new business process. Modelling and simulation are performed throughout Bonita Open Solution tool, which was assessed and selected from a qualitative benchmark for Business Process Management Systems (BPMNs). Besides quality tests as cyclomatic complexity, branches and functional tests were performed on the proposed process to guarantee the correct execution of it.

A new method for urban flood monitoring based on fuzzy logic for issue alerts on a geographic map was showed. The model is designed to receive information from remote sensing water level over TCP/IP protocol and operate intelligently based on fuzzy rules with inference by Mamdani model from urban open data, providing free information access containing flood alert states and flooding with georeferencing that can help cities to become smart cities. The model was validated by case studies analysis with real sensors that generate a set of pre-planned test data. The issue alerts on geographical maps in real-time corroborated presented in this work for the acceptance of fuzzy logic in the urban monitoring flood with high performance, being able to act autonomously providing information to drivers for avoid undesirable routes.

In the literature, different models are proposed to manage the Requirements Engineering, which present advantages and disadvantages when properly specified customer requirements. In order to identify good practices of these models, a literature review was conducted to assess the characteristics and potential of the most popular. The results are described in this work, and concludes that a model to manage the requirements engineering should gather good practices found, and potentiate them with contributions from other areas of knowledge, as formal methods, discrete mathematics, logic, abstraction, and other related. This is because the current problems are more complex and complicated than before, security has become a key issue, the changes are every day, and delivery times of the software products have been drastically shortened, while budgets must be adjusted to their service life.

Group formation is an important topic in Computer Supported Collaborative Learning (CSCL) because that has implications in the group performance. In this paper, we propose a genetic algorithm for automatic generation of groups considering learning styles of your members. The group formation with genetic algorithm is a permutative problem, for this reason, genetic operators were designed. We use historical data about performance of groups and we create association rules which are used in the fitness function. The algorithm proposed was analyzed with different size of groups given for the teacher. Through the experimentation we can see what kind of configuration tends to be more appropriate.

The aim of this paper is to show how the use of a fuzzy logic system associated to the amount estimation of items in stock can reduce the required amount of spare items of a purchase order, making it possible to determine with greater precision the minimum purchase lot for an order and so minimizing storage costs. Keeping lower the average stock levels without causing shortages and further decrease in service levels, companies can ensure free capital for investments in other strategic areas and have fewer losses in the case of perishable products unnecessarily stored for long periods.

The use of computers in the Collaborative Learning (AC) domain, allowed defining new scenarios for teaching and learning, creating Computer Supported Collaborative Learning (ACSC) systems focus on group dynamics to facilitate learning. Within a group effective collaboration is conditioned, among other factors, behaviors or roles that its members expressed during the working dynamics of the group. This paper aims to develop a software agent to analyze the participation of students in a group, recognize the phases evolving dynamics of group work and roles students to work collaboratively. To do this, a recognized theory of team roles was analyzed and the algorithms needed for the agent to perform the proposed monitoring are being designed. These algorithms are coded and integrated with the agent in an application, and then validate their operation through experiences made with collaborative groups of students.

Currently, due to ease of acquisition of mobile devices and their increasing processing power and storage, many applications in various areas and services have been developed. With access to information held by Internet, many data and research institutions are accessible in repositories in popular formats and they are made available for use by users and developers, such as the Brazilian Portal of Open Data. Due to the transport area is a recurring theme in the Brazilian daily, causing many disorders in big cities, we focus in the the vehicle fleet visualization of Brazilian capital. In this sense, this article aims to propose an application for mobile devices, called cARFleet, to open data visualization. In the application were incorporated features of augmented reality for better visualization and differentiation of the tool.
