Discussions on environmental issues have started years ago. In fact, recently, this issue has been discussed considerable because of the perception of the damage caused to the environment regarding the resulting pressures of social development on natural resources. Different sectors of society have adopted sustainable practices as a means to contribute to minimizing such damage. In this scenario,...
Nowadays the transportation systems show new challenges in management and supervision issues due to amount of vehicles and the variability and extension of the roads. New technologies have been developed to get information about traffic in cities. Nevertheless, new frameworks with different technologies applied to traffic monitoring have not been well defined. In this paper, a new framework with Radio...
In this short paper we present an overview of MEIO (My Environment is Outstanding), an m-learning tool for environmental education combining aspects of social networks and gamification. The conceptual design of MEIO aims to foster the objectives of environmental education according to Tbilisi Declaration, to wit, awareness, knowledge, attitudes, skills and participation, in urban communities. The...
As a result of population growth in large cities face everyday problems related to urban mobility such as congestion, quality of urban roads and inefficiency of public transport. Intelligent transport systems initiatives act as an efficient solution to improve the functioning and performance of traffic systems, reducing congestion and increasing safety for citizens. However, due to the inclusion of...
The rise of wireless technology and mobile devices has increased the number and types of resources to be integrated to the grid. As a result, the concept of grid has been enriched and new categories have emerged. One of these new categories is the mobile grid, which include mobile devices as resource providers. Many articles have been written in the past decade about mobile grids. These include surveys,...
The context of this research is the use of Unmanned Aerial Vehicles (UAV) to search and localize a target. The problem to be solved is the cooperative behavior of the UAV group to optimize the search. The focus of this research is the use of bioinspired algorithms to spread the aerial vehicles and the optimization of the time of search, comparing the application of Particle Swarm Optimization with...
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...
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...
This article proposed an econometric model ARIMA(p, d, q) is presented as a tool for controlling LAN congestion. To achieve this objective should make the revision of the time series as a way to measure, understand and analyze data networks, as well as the behavior of the shares in a stock exchange. So the concept of the time series for actions and data networks to engage with this model propouse...
Apply theory and practice is usually a difficult task to lead in undergraduate courses. Generally disciplines involving development projects are used as an attempt to minimize this difficulty. One way of conducting this kind of discipline is defining a development methodology to be applied. This paper aims to present an approach based on design thinking to develop products and services that involve...
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...
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...
Se presenta un estudio que explora la disposición de los estudiantes de los programas de Ingeniería de Sistemas, Ingeniería de Telecomunicaciones y la Especialización de Seguridad Informática de la Universidad Piloto de Colombia a participar en actividades relacionadas con delitos informáticos o una cultura hacker, teniendo en cuenta principalmente su entorno académico y la relación con los docentes.
Smart City is a concept used to describe a city that uses technology in order to improve the quality of life in the urban environment. One way to contribute to the improvement of urban life is the optimized use of resources. Given the high price of gasoline in Brazil and aiming to improve the quality of urban life, we developed a mobile application that uses fuzzy logic and data read from a OBD-II...
This paper proposes a framework, called Ubiquitous Laboratory for Practical Activities (u-LabPA), which allows students to bring in data from laboratory practices and access them retrospectively in the form of simulations or virtual environments. Simulations were conducted using Petri nets to analyze the system behavior and its application in a physical Laboratory.
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 analyze the JClic and Hot Potatoes tools and their behavior in e-learning environments. These tools are meant to create activities and exercises of the ministry contents by the teacher. Such tools have their specific characteristics and do not always meet the proposed in their concepts. It was used for this work a broad literature search in papers and publications found in repositories...
A continuación se presenta el sistema de información WEB implementado para el proyecto de investigación titulado “La circulación de la doctrina en la jurisprudencia constitucional colombiana” enmarcado en la investigación internacional sobre los Tribunales Constitucionales y Supremos en el mundo, describiendo los desarrollos implementados para estructurar un sistema de información que a través de...
In a computer supported collaborative learning environment, students are organized into groups and work together to achieve a common goal, using the computer as a communication, collaborate and coordination tool. Under the premise that every student in a group behaves in a certain way to collaborate, thus demonstrating a learning style, this research demonstrates the existence of certain relationships...
