Abstract
Higher education is a complex business including very different process. At its core are the teaching and research processes and along the edge of the business model are the administrative processes, targeted to the students and alumni. Some of these processes translate into services that must be available during the whole life of the users and the institutions. For example, a higher education institution is expected to issue diplomas during the whole lifetime of its former students. In this context, we've been working in order to use the current e-government infrastructure of electronic services as building blocks for some of the features of the higher education institution electronic services. This work proposes the adoption of a set of those services. We've concluded a successful testing stage and expect to deploy a full production system very soon. Copyright

Abstract
Average life expectancy of the humans has been increasing with the advancement of medicine, hence observing an aging of the population in general. Associated with aging, loss of cognitive ability and memory failure are often observed, which can have a great impact on the quality of life and autonomy of people who need to take medication on an hourly basis. In this work, we present the development of an application that helps to manage two key issues for the quality of life of the elderly: the time of medication and the time of medical consultations. The application is managed (information is added, altered or deleted) by a responsible, as a family member or health professional. After analyzing several solutions, it was verified that the biggest problem identified is the difficulty of interaction with the interface (sometimes it presents a lot of information and do not focus on functions of immediate necessity). In this context, we present a solution that focuses on two main objectives: first, to present a clear and simple list of medication and list of information of consultations; and second, to provide a simplified interface for the management of medication by a caregiver (child, nurse, and tutor). In the first development phase, we evaluated the usability of this interface, with ten health care professionals, who evidenced the potentiality of the solution presented here.

Abstract
In this paper an augmentative and alternative communication mobile application for people with language and speech impairments, called Diga Ola, is presented. With this mobile application, we aimed to assist people with speech and language impairment in their communication process, by presenting an alternative mobile solution in Portuguese language. The main results achieved on a preliminary user assessment were: first-rate performance, higher satisfaction and total autonomy in their interaction with the solution presented.

Abstract
The safety of people and spaces is of paramount importance for societies. With time, the implementation of safety measures is rapidly changing from a need to a priority. Video surveillance systems play a key role in the surveillance of crucial and critical areas as these systems help the authorities keep places safer. With the rapid growth of technology and the implementation of the smart city concept, it is becoming possible to develop and deploy wide area surveillance systems. The ease with which these systems can be installed in private and public spaces (e.g., homes, streets and parks) allow for the creation of ubiquitous monitored environments. Rapid intervention responses to any abnormal situation or the use of recorded video as evidence are some advantages of the use of this type of surveillance systems. Although ubiquitous video surveillance systems are relevant for present modern societies, their cost is still high. To solve or, at least to mitigate this problem, a low-cost smart surveillance system was developed, which is presented and described in this paper. The developed surveillance system, based on available low-cost technology, can help keep critical spaces under surveillance 24/7. The proposed solution was found to have a minimal cost, a low bandwidth, and to be scalable and adaptable to every client’s needs. Thus, the solution can be used by anybody (private and public) and applied in different contexts (e.g., residential, industrial). The system can provide still images, captured from surveillance video cameras, real time video and real time video processing, which can be used for motion detection. When this happens, the user is warned via an e-mail containing the identification of the respective surveillance camera. Only the relevant video events are sent, recorded and maintained in the cloud platform system, consequently reducing the amount of storage space required to maintain all the historical video events. The results of the tests carried out show that it is possible to stream a video from the surveillance cameras with an insignificant delay and that motion detection can be attained through real time video processing. The system presented potentiates a low-cost solution for a smart city in the surveillance field. © Springer International Publishing AG, part of Springer Nature 2018.

Abstract
The peripheral arterial disease (PAD) is characterized by leg pain during walking, and a recommended treatment for this disease is to perform supervised physical activity. In this chapter, a system that monitories the physical activity containing one application for smartwatch, one application for smartphone, and a back-end webservice is presented. The applications collect heart rate, GPS locations, step count, and altitude data. The methodology used for the development of the system was based on the agile method with the production of prototypes. In this chapter, four development cycles, which cover the users' and researchers' needs, are presented. In this work, the main objective is to evaluate the current mobile technologies on the physical activity data collection and the development of a system that assists the users to maintain an active life. © 2018, IGI Global.
