This paper presents a target-specific programming language (TSL) that was designed to improve the design cycle of code generation for an industrial embedded system. The native assembly code, the new language structure and their constructs, are presented in the paper. The proposed TSL is expressed using words and terms that are related to the target’s domain and consequently it is now easier to program, understand and to validate the desired code. It is also demonstrated the language efficiency by comparing some code described using the new language against the previous used code. The design cycle is improved with the usage of the TSL because description time and debug time are significantly reduced with this new software tool. This is also a case of university-industry partnership.

The dissemination of large displays and personal mobile computing devices has created new opportunities for the joint use of these devices. Together these devices can enrich public spaces, promoting new and more engagement interaction mechanisms, giving users relevant information and providing important resources that can promote conversations and group activities. In this paper we explore the joint use of public displays and personal mobile computing devices, as equipments for the dissemination of personalized information that is delivered to users according to their interests and expectations. Three main aspects characterize our proposal. First, it encloses in the same system two types of devices for delivering information: mobile devices and large public displays. Second, the user only receives information of his interest point of view and the information is delivered through the most proper device. Third, our proposal combines into the same system two different perspectives: informative, providing users with information about their subscriptions and socializing, i.e. presenting, in a public display, information about the place, about users’ interests and about interests of other people that visits the same place. We have developed and evaluate a partial prototype based on those principles. The results show that the system is easy-to-use, that it can support a wide range of activities and that the users recognize an added value of the system comparing to traditional approaches.

Nowadays there are a vast number of devices and technologies available for the common citizen to improve their communication with others. This fosters the design and implementation of systems that explore the available features of these devices. This paper presents a system that allows to inform, on a personalized way, the actors of an education institution on a free way using popular communication standards. Features like the system’s architecture, prototype and system’s evaluation are explained in the paper. Results show that this system can be an important complement to other popular systems in education environments (e.g. e-mail, chats, Wikis, forums, e-learning platforms etc.).
