It is di cult to maintain legacy Fortran programs that use outdated programming constructs, especially when this maintenance requires a detailed understanding of the code (e.g., for parallelization). Initially, we want ...

"There is a general belief that the quality of Twitter data streams is generally low and unpredictable, making, in some way, unreliable to take decisions based on such data. The work presented here addresses this problem...

In spite of years of research and development, formal structured estimation of time and effort required to develop a Management Information System (MIS) is still an open problem. Usual estimation techniques applied by no...

In this work, a conceptual framework and the associated strategies for metrics and model validation are analyzed regarding website measurement and evaluation. Particularly, we have conducted three case studies in differe...

Given the central role that software development plays in the delivery and application of information technology, managers are increasingly focusing on process improvement in the software development area. This demand ha...

Framework comprehension is a very limiting factor to take full advantage of the benefits that frameworks offer to increase quality and productivity in software development. In this paper, a reverse engineering approach t...

The input of text on mobile devices has evolved from physical keyboards to virtually displayed touch keyboards. The aim of the paper is to assess and compare two mobile phone text input methods (mini-QWERTY and on-screen...

Most of the current hypermedia model life cycles focus in analysis and design issues, ignoring crucial tasks and activities of hypermedia projects. Others do not take care of basic Software Engineering concepts such as p...

The Standardization of a development process for systems of medium complexity, entirely supported by an integrated development environment, could mean a double contribution to the industry of systems development. On the ...

A social network is formed by a set of actors and the relationships established by them. SNA leads to distinct goals and perspectives of social network analysis and computer science. This paper introduces the study of so...

UML models quality is clearly a crucial issue that must be evaluated at the initial stages of object-oriented software development, in order to get software products with better quality. This fact is corroborated by the ...

Complexity metrics are useful measurements to ascertain the quality of software. However, the metrics are only applied and isolated in one specific development phase and they can not trace the quality (and the evolution)...

SUMMARY: Picante is a software package that provides a comprehensive set of tools for analyzing the phylogenetic and trait diversity of ecological communities. The package calculates phylogenetic diversity metrics, perfo...

SUMMARY: Limitations of genome sequencing techniques have led to dozens of assembly algorithms, none of which is perfect. A number of methods for comparing assemblers have been developed, but none is yet a recognized ben...

In this work we present a discrete event model to design and implement a real time system simulator. This kind of software is useful to verify and evaluate algorithms and models, and to compute performance metrics. The d...

"There is a general belief that the quality of Twitter data streams is generally low and unpredictable, making, in some way, unreliable to take decisions based on such data. The work presented here addresses this problem...

The evaluation of metric of performance is useful in the evaluation of protocols, in the improvement of applications, in the content choice, among others. The obtaining of these metrics, it continues being a complex task...

Computation technologies and computer tools offer varied resources for the implementation of applications of electronic commerce (e-commerce). The current organizational models are based on nets of associations that are ...

This survey provides an overview of higher-order tensor decompositions, their applications, and available software. A tensor is a multidimensional or N-way array. Decompositions of higher-order tensors (i.e., N-way array...

The Unified Modelling Language (UML) has become a defacto standard for software development practitioners. There are several tools that help the use of UML. Users of those tools must evaluate and compare different versio...

The development of languages allowing a proper handling of time is important in many areas of computer science because the capability to deal with the notions of change and time are essential to solve their problems. In...

Time and change are notions that seems unavoidable in some areas of work and investigation, languages that can deal with these notions are necessary. At the same time, methods for a proper time handling are quite complex...

The use of component-based software has become more and more important in state-of-the-art and state-of-the-practice of software and system development. Using COTS software promises faster time-to-market, which can yield...

In this position paper, the main steps to measure and evaluate quantitatively the quality of sites are shown. Besides, some specific models, criteria and procedures to apply in these activities are discussed by quoting c...
