Abstract
Rich Internet Applications (RIA) technology leads to new opportunities in Web development, adding a new level of usability and overcoming several limitations of traditional Web applications. However, there are still a few gaps in RIA development, namely the lack of methodologies enabling direct evolution of traditionally developed Web applications into this new concept. This paper describes a methodology to adapt User Interfaces (UI) from Web 1.0 into Web 2.0 introducing RIA capabilities, maintaining the business logic and data access layers legacy. The main system architecture is maintained and the new concept is achieved by adding a new Web services encapsulation layer responsible to intermediate the business logic layer and the new UI layer, providing a seamless and dynamic integration. For validating this methodology, a prototype was developed by applying and evaluating the suggested methodology. The results obtained validate that this methodology is appropriate for the given problem. © 2009 IADIS.

Abstract
The preservation of musical works produced in the past requires their digitalization and transformation into a machine-readable format. The processing of handwritten musical scores by computers remains far from ideal. One of the fundamental stages to carry out this task is the staff line detection. We investigate a general-purpose, knowledge-free method for the automatic detection of music staff lines based on a stable path approach. Lines affected by curvature, discontinuities, and inclination are robustly detected. Experimental results show that the proposed technique consistently outperforms well-established algorithms.

Abstract
Prevalent in today society mobile devices indeed come with technical capabilities offering both complex software applications and location-based services. However, seldom are the mobile-devices software and hardware potential fully exploited, seen that the navigation-aid systems are the most ordinary and significant advantages being taken from such capabilities. Furthermore, bringing environment-contextualized information and services to users through their mobile-devices seems yet to be roughly explored as an electronic business. For example, when someone is on tour and spontaneously wants to find information, or want to book/buy tickets, concerning cultural events taking place in their geographical surroundings, up to present, it is not known an available system or service capable of providing it. To overcome this problem, we propose a new ubiquitous events promotion e-business system, which enables one to search for cultural events based on geographic location, also supporting ticket-booking, ticket-selling and ticket-validation services.

Abstract
As the internet becomes the most significant source for seeking information and acquiring services, the problems raised by the lack of usability and accessibility on websites lead to problems of e-exclusion, which phenomena may potentially have a great impact on one's life. Although some groups of individuals with special needs, namely the visual disabled people, have received the help of researchers to overcome the problem of accessing the information, there are other groups, particularly intellectually disabled people, that received little attention, indicating that their ability to access information is still limited. In this paper we present a study that investigates how people with the mentioned intellectual disabilities interact with web pages, which difficulties do they have while accessing the information and we propose guidelines for the studied group. While conducting this study we have also analyzed how the guidelines (1.0 and 2.0) suggested by W3C are applied to this particular group.

Abstract
The amount of seniors in need of constant care is rapidly mint! an evident consequence of population ageing. There are already some monitorization environments which aim to monitor these persons while they remain at home This, however, although better than delocalizing the elder to some kind of in may not still be the ideal solution. as it forces them to stay inside the home more than they wished, as going out means lack of accompaniment and a consequent sensation of feat In this paper we propose EM on a monitorization device small enough to be worn by its users, although powerful enough to provide the higher level monitorization systems with vital information about the user and the environment around him We hope to allow the representation of an intelligent environment to move with its users, instead of being static, mandatorily associated to a single physical location The first prototype of EMon as presented in tills paper, provides environmental data as well as GPS coordinates and pictures that are useful to describe the context of its user

Abstract
Human collective set of experiences makes us who we are and help us delineate a path for our ongoing life. Ageing, however, progressively limits our ability to save, in our internal memory, these same experiences, or, at least, limits our capability to remember them. The capability to remember, intrinsic to our memory, is a very important one to us, as a human been, being this what deferent's us from several other species. In this paper we present a memory assistant sub module of a bigger project, the VirtualECare, which ability will be to remember us, not our past experiences, but our routine day-to-day tasks and activities, in a somehow proactive manner, thus, allowing us to have some relaxation about them, and focus the remaining of our ability in most important facts.
