Researchers in the field of Augmentative and Alternative Communication point out the lack of instruments for assessing children and young people with a complex communication needs. This study's focus is the selection of words for creating an instrument for the vocabulary range in non-speaking children aged two to eleven years and eleven months. Three studies were performed. The first study identified and described tools available for assessing receptive vocabulary and their respective word lists. The second identified and described research that presented word inventories or word lists. The third study identified the vocabulary reported by parents and teachers. The words that were identified in the three studies were analyzed according to: the number of times they occurred; the Picture Communication Symbols system classification; and a semantic and syntactic classification. Based on these studies the following criteria for vocabulary selection were established for word selection: the 45 words which appeared in all three studies, the words that occurred five times or more, considering the three studies, representing 167 (14.14%) words; the words identified in study one or two, but that had been reported by the families - 183 (19.37% out of 945 words) - or by teachers - 108 (11.43% out of 945 words). The word list was composed of 269 items, classified in 18 semantic and syntactic topics; it represents an initial tool for professionals in the field of health and education to set goals for beginning assessment of children and teenagers who are users of Augmentative and Alternative Communication systems.

Smart grids are the focus of major study today because of the necessity of modernization in electrical systems and reduction of greenhouse gas emissions that increases global warming. Reaching the best deployment method, you must first of all know the current electrical system and how to use them for the benefit of this new technology. Preparing the action plan we should be aware of the main points of smart grids in each step of the electricity system - generation, transmission and distribution. Analyzed these topics, this work will focus on the first step in the implementation of the smart grids: the smart meters, tool which is already being implemented in Brazil. The main characteristics and applications of these devices, as well as their communication structure with the core distributors will be showed during the paper. Finally, we present a case study which will be discussed and analyzed based in the results obtained with the implementation of smart meters in the city of Vancouver, Canada, where we have a considerable savings already in the first year, with fully paying the initial investment and still have a profit
Recebimento de dados GNSS via Internet em RTCM 3 e conversão para RINEX utilizando a plataforma J2ME

Changes are occurring worldwide, including the area of positioning using Global Navigation Satellite Systems in mobile devices such as mobile phones or laptops. This is due to the great improvement and availability of Internet services to these mobile devices. The accuracy and speed of data transmission for these devices makes the technology of sending / receiving data via an internet targeted for optimization. The optimization could allow obtaining, in real-time, coordinates (latitude, longitude and altitude) of suitable quality for users of GPS (Global Positioning System) devices that have wireless Internet access, such as those used to control the eet, locomotion, navigation, agriculture, etc. . The use of the protocol NTRIP (Networked Transport of RTCM via Internet Protocol) in GPS applications is growing every day. Applications are available in C, which creates an opportunity for development with a focus on multiplatform environments. In this context, we propose an application, implemented in a multiplatform environment and the use of NTRIP, able to run on a mobile device for receiving GNSS data

Didactic texts compose communication and representation systems. By them societies communicate with their children, their youth, transmit them live representations, symbols, ways of understanding speeches and delimit their study fields. This article presents a discussion about the medias used by Portuguese language text books selected by the Ministry of Education Textbook National Program (PNDL – in Portuguese), in order to observe the foundation of actions, movements and media insertion at school. The analysis allows us to see the consolidation of an individualist profile among the strategies of using medias at school, among others aspects.

This paper presents a study based on bibliographic research on LTE technology, chosen for the fourth generation of mobile phones, and the current status of implementation of 4G network in Brazil. The change in user behavior, which now uses data over the voice services, requires transmission networks to be increasingly robust and fast to enable the viewing of videos and use of other platforms that require internet connection. The retrospective of the development of mobile technologies, from 1G up to 4G that is currently used, shows the long road until it came to appliances and how the phone is used nowadays. Finally, the popularity of smartphones and hence the growing number of people with access to 4G networks, demanded new researchs for the development of future generations technologies in order to achieve the demand for speed enabling significant changes in user experience
