Abstract
Software testing is an important component that leads to quality software production. This paper presents the results of a framework for assessing the level of maturity in Software Testing application in the context of Small and Medium-Sized Enterprises (SMEs) based on TMMi model. Our framework includes an evaluation questionnaire based on TMMi sub-practices, support tools with examples of artifacts required to ensure that the questionnaire is thoroughly completed, as well as an automated tool support for its application, enabling SMEs to carry out self-assessment. The framework was applied in ten companies and before the results presented, it can be concluded that the companies maturity in software testing is low and that the companies positively assessed the adequacy of the framework developed for the context of SMEs.

Abstract
In order to ensure the access of the visually impaired to all information provided online it is necessary to remove existing barriers on the websites through several existent approaches, from recommendations to web development to validations of existing websites. The issues on navigating through the web that are detected only during the user's interactions on the sites, creates a need to evaluate this user's interactions aiming to ensure the web accessibility. So, in this scenery, this study uses previous researches on the subject and web accessibility rates in order to identify those barriers commonly founded by these users with total visual impairment, as well as to come up with a list of recommendations in order to optimize the evaluation process.

Abstract
Due to its general usage in modern buildings, WiFi has been studied as a promising good low-cost solution to build localization services, but many other approaches are possible. Both industry and academy are putting considerable efforts in studying affordable and accurate alternatives, and no de facto standard exists yet. While technological diversity can be good in terms of flexibility, allowing distinct solutions to be used in distinct contexts according to accuracy needs or cost constraints, it is also a big obstacle to the goal of building a global positioning system. So one important requirement that has yet to be addressed is this diversity, allowing for multiple localization systems to be easily plugged into a standard and global localization service. In this paper, a solution to build a global localization service able to integrate various heterogeneous localization systems is presented and discussed. A prototype implementation built on top of DNS is proposed. The DNS subtree structure, as well as the Resource Records able to store the localization information, are presented and justified. The results obtained from prototype testing have proven that DNS is a valid and good candidate to support a global Localization Service.
