The widespread deployment of tagging systems and sensors has resulted in huge streams of events that are automatically captured and must be processed by monitoring and reactive applications. Simple observation events are further aggregated and composed and used to derive complex events of higher level of abstraction, often by enriching the observed events with information from external sources. The...
Software architectures have emerged as a promising approach for managing, analyzing, building, integrating, reusing, and improving the quality of software systems. Specifically, early design decisions can be improved by the analysis of architectural models for different properties. This paper addresses the problem of estimating the reliability of data-flow architectures before the construction of...
As organizations become more and more process-centered and as the extended enterprise becomes more of a reality, there is an increasing need to move toward the intelligent enterprise characterized by its agility for provisioning resources and services and the adaptation and optimization of its business processes. Many are the challenges that need to be faced to equip the extended enterprise with intelligence,...
This paper focuses on the development of service-oriented information systems. One of the main challenges facing service-oriented computing is providing methodologies that support the specification and design of IS behavior, and allowing software engineers to move from the earlier stages of business analysis to its final step of implementation. Model Driven approaches provide with models, transformations...
Understanding and characterizing the nature of indoor mobility is an essential requirement for developing proper mobile technologies. Yet, a detailed study of indoor mobility in real scenarios represents a challenge as it requires intensive labor from researchers and a level of intrusion which is not always welcome by participants. Previous research in mobile environments has been based on observational...
This paper introduces an approach for adaptively brokering queries for exploiting streams produced and consumed by devices with limited computing and storage capacities. Such devices can be mobile and static and they can build networks for exploiting streams by evaluating queries in a collaborative way. Query brokering strategies are based on the notion of relevance which depends on application requirements...
The present paper proposes the use of a basic element for the infant cry analysis: the cry unit. In order to display the real possibility of the cry unit for the detection of pathological features (based on Hypoxia) in newborns, a novel combined treatment of the cry signal was implemented using an evolutionary-neural system. For that purpose the cry signal was segmented into cry units, the MFCC were...
Fuzzy cellular models (FCM) are a combination of cellular automata (CA) and fuzzy logic (FL). FCM are used to simulate complex dynamics ecological systems that involve space and time. The goal of this paper was to define a population growth model as a transition function that determines the state of each cell. The transition function involves FL to model variability of mortality, reproduction and...
The usage of e-learning tools has brought an immediate benefit to the teaching field for both academics and students, allowing them to have a better administration of time and a permanent access to the class content. Moreover, the increase in the use of mobile devices is becoming more notable as it is the need for accessing information from any place one is at is more extensive. The enormous popularity...
This paper presents an experience report on the development of a network management application in the context of a small IT Mexican firm (PyME). In this firm, whose main focus is not on software development, a development team was created specifically for the project. Although the environment of the project was not particularly ldquosoftware-engineering friendlyrdquo, the development team made an...
We present the design and implementation of a Web services orchestration engine developed to support the WebContent semantic Web framework. This framework is under development in the context of the WebContent project, whose goal is to provide a scalable and robust platform for the development of semantic content management applications for diverse domains. The WebContent framework is based on a set...
Summary form only given. Ordinary people have access to unprecedented volumes of information today. Researchers in the fields of information management (IM) and human-computer interaction (HCI) are reacting to this challenge from their own unique perspectives. Having access to a billion records is cool, but having access to a billion people is awesome. In this talk, we look at recent research from...
