Differences in prices registered in market research studies are common. Visualization of the price differences is difficult to develop and understand as several attributes are considered by the analysts. An alternative to visualization of the price differences is sonification, a kind of auditory display, in which these attributes and relations are translated into sound. In this paper we present a parameter mapping sonification for differences of prices in market research studies. As a proof of concept, we show results from an implementation of the sonification which creates four samples, one for each category of differences defined in this work. Also we describe its use and its benefits in a real market research environment.

Este artigo discute o uso de dispositivos móveis na sala de aula considerando um recorte da realidade universitária baiana. Para tanto, utilizou-se de artefatos da pesquisa qualitativa, buscando adentrar o cotidiano da sala de aula do ponto de vista discente. Ponderando vantagens e desvantagens de tal uso, percebemos que a dispersão é o grande desafio que se põe para professores e estudantes. Porém, isso não significa que para estes últimos tais dispositivos devam ser extintos da sala de aula, mas sim contextualizados de uma melhor forma. Finalmente, também notamos que o uso de dispositivos móveis pouco tem favorecido o processo de construção no âmbito coletivo, diferente do que pode ocorrer na esfera individual.

The research paper describes the development of a user friendly 3D virtual world. For the research, we modeled building number 3 of the Technological University of Panama, Victor Levi Sasso Campus. For the virtual world development we consider the use of an avatar, which becomes the user's virtual representation that interacts with certain objects in the virtual world. The tools and resources used, because they facilitate the interoperability, were the following: Computer Aided Design software (CAD), Computer Aided Architectural Design (CAAD), Virtual Reality Technology, Videogame technology and 3D game engine.

The recommendation systems aim to minimize information overload by helping user's in searching desired information. Faced with this scenario, we investigate the use of cloud factors able to have a positive influence on generating recommendations. Thus, we present a new, simple model based on cloud features which is associated with the content-based technique of recommendation. The practical applicability of data storage environments in the cloud provides the best use of cloud resources and meets user's preferences.

The larger amount of motor vehicles produces many problems to cities around the world as poor urban mobility, environment concerns and people's health. The encouragement to use alternative means of transport, such as bicycles or subways is one of the steps to solve the problem. Another way is to encouraging the optimal usage of private automobiles. In Brazil, for instance, several studies show an underused space in cars and great potential for the use of carpooling and carsharing. Unfortunately, there is not such a unified technological mean to properly support these alternatives. In this paper we propose and implement a social network to support the use of carpooling. We show that there is a favorable context for the use of this social network with the specific purpose to share rides among users. We describe the architecture of the system and implementation details. We present results about systems's accessibility and its acceptability by people around the globe.

Software Systems usually demand product customization for each client, frequently involving the creation of new components and changes to existing ones, possibly causing maintenance and evolution problems. One of the major challenges is to keep source code quality of the customized code. This is specially difficult because the revision process of the customized code can not be automated by existent tools. These tools are known as static analyzers and are important to automate the inspection of source code. However, the main Java language static analyzers lack flexibility, which makes the use of these tools impractical in some projects. Moreover, each o them has a different focus, which leads developers to use more than one. This paper presents a new tool (CodeAnalyzer) that integrates the main Java language analyzers, providing more flexibility and solving some of those problems. It is briefly compared with Sonar and SQE.

Computational efforts for Alternative and Augmented Communication (AAC) must deal with two important issues, that slow down their spread: (1) the need for specific hardware and software in order to engage each different disability and (2) the different communication languages. This paper presents the PickNClick, a hardware/software apparatus that allows for ample AAC in Brazil. The PickNClick consists of a word and sentence prediction tool for Portuguese language to help people with cerebral palsy, in particular, spastic quadriplegic children. Experiments conducted presented good values concerning KSR metric and showed the software applicability cerebral palsy and spastic quadriplegic volunteer.

A number of methods, languages, tools and techniques are widely used in Software Engineering projects even before being formally evaluated in practice. In critical phases of software life cycle, such as requirements engineering, this practice may lead to deceptions. In this paper, an evaluation of the Systems Modeling Language (SysML) diagrams and constructions when applied to requirements engineering activities is proposed. This evaluation was performed based on the Technology Acceptance Model (TAM). Three criteria were used to evaluate the acceptance of SysML as a language for requirements engineering: perceived usefulness, perceived ease of use, and perceived usage. The evaluation was performed in practice in a company that develops software-intensive systems.

In many countries, the responsibility for issuing disaster alerts to the general population lies with different local, regional, or national authorities. These disaster alert systems are usually managed independently and without any automatic co-ordination. However, it would be highly beneficial for system operators (a) to obtain an overview of the crisis communication that other actors have already undertaken, and (b), to integrate as many dissemination channels as possible to maximize the impact of alerts. This paper presents a concept for such a holistic alert solution, as well as a prototypical implementation of the system. The prototype also allows for a personalization of alert messages for different groups of recipients such as tourists or people with different types of disabilities.

Supervisory computer systems are crucial for electric utilities to monitor the performance of the power system, analyzing equipment safety and reliability, and helping system operators understand what is happening throughout the power network. Some of those systems need to be integrated in order to support the routine operations. In most cases, however, such integration is not automatic, requiring visual access to information displayed on different screens, inference about equipment status, retyping of common data between systems, and others. This study analyzed data from a large electrical power transmission company, and found that a significant number of maintenance requests, for example, are canceled due to typing errors or inconsistencies caused by the lack of context information. This paper presents the architecture of a context-aware middleware and a prototype implementation that allows the integration between a supervisory control and data acquisition system (SCADA), which monitors the power network in real time, and other power-system software applications. It is shown that the use of context awareness has enabled the handling of information in an integrated and flexible manner, helping users make consistent decisions in the planning and supervision of a power system without having to access different screens of the software applications involved.
