An Engine Oil Replacement Timeline
Neves, José; Ferraz, Filipa; Vicente, Henrique; Novais, PauloEngine oil conditions are crucial either for the proper engine function and to calculate the oil´s lifetime. Factors like rotation per minute, temperature, trip length, clarity of the oil is important to determine the level of contamination of the engine oil. Thus, the type of engine heating cycles, the power of the engine and the components of the oil used are also factors that determine whenever oil replaceme...

Transfering data from a server to an Android Mobile application: a case study
Anacleto, Ricardo; Figueiredo, Lino; Almeida, Ana; Novais, PauloNowadays, due to the incredible grow of the mobile devices market, when we want to implement a client-server applications we must consider mobile devices limitations. In this paper we discuss which can be the more reliable and fast way to exchange information between a server and an Android mobile application. This is an important issue because with a responsive application the user experience is more enjoyable...
A web platform and a decision model for computer-interpretable guidelines
Oliveira, Tiago Gil; Novais, Paulo; Neves, JoséSituations of medical error and defensive medicine are com- mon in healthcare environments and have repercussions in the quality of care under o er. The occurrence of adverse events and the increase of healthcare expenses are some of the consequences of medical malpractice. Indeed, these situations may be prevented by encouraging the compli- ance with Clinical Guidelines (CGs). However, the current format of CG...
A statistical classifier for assessing the level of stress from the analysis of...
Carneiro, Davide; Novais, Paulo; Gomes, Marco; Oliveira, P. M.; Neves, JoséThis paper describes an approach for assessing the level of stress of users of mobile devices with tactile screens by analysing their touch patterns. Two features are extracted from touches: duration and intensity. These features allow to analyse the intensity curve of each touch.We use decision trees (J48) and support vector machines (SMO) to train a stress detection classifier using additional data collected ...

A visual analytics framework for cluster analysis of DNA microarray data
Castellanos-Garzón, José A.; García, Carlos Armando; Novais, Paulo; Díaz, FernandoProva tipográfica ; Cluster analysis of DNA microarray data is an important but difficult task in knowledge discovery processes. Many clustering methods are applied to analysis of data for gene expression, but none of them is able to deal with an absolute way with the challenges that this technology raises. Due to this, many applications have been developed for visually representing clustering algorithm result...
