Abstract
Customer relationship management is a business strategy which dynamically integrates a set of services with the purpose of creating value for the organisation and for their customers. In Portugal, the 2009/2010 edition of Simplex for Municipalities', the action plan carried by the Portuguese government through the Secretary's Office of State for Administrative Modernisation, makes a commitment to promote a set of initiatives in order to help citizens using the public services. This process intends to reduce costs of context which burden the economic activities, making way for the modernisation of administration. Customer relationship management assumes a central role in this context. This paper presents the main results of a survey that was carried out with Portuguese municipalities, aiming a general characterisation of the adoption of customer relationship management systems, covering several aspects, from the motivations for CRM adoption to the obtained results. The improvement of the relationship with citizens and a higher information quality are some of the most important results obtained by municipalities.

Abstract
This paper presents an educational tool to be used in signal processing interpolation-related subjects. Besides the consolidation of acquired theoretical knowledge, the tool allows its users to apply three error patterns geometry to the signals and test minimum dimension and maximum dimension signal reconstruction algorithms. In the specific case of minimum dimension problems it can be solved using different solvers, iterative and direct linear equations methods. The developed tool allows the problem conditioning analysis through the spectral radius of the system matrix, the condition number and others parameters available in some specific methods. This feature gives the possibility to alter the problem definitions to the desired goal before the reconstruction begins and to choose the optimal method, depending on each problem constraints The time unit that measures the algorithms performance is expressed in terms of one Fourier Transform (FFT) calculation time. In this way the data is presented not in an absolute way but in a relative measure independent from the machine's architecture.

Abstract
In clinical practice, high-resolution computed tomography (HRCT) is a reference in the diagnosis, quantification, and follow-up of lung emphysema. In this study, differential lacunarity analysis was applied to HRCT images of the chest in order to quantify the texture of healthy and emphysematous regions of the lung parenchyma. The used approach to compute lacunarity is a multiscale technique that takes advantage of the extensive scale used in the acquisition of CT images. The results show that the extracted features are discriminatory of the considered lung patterns, being suitable to integrate clinical applications for the characterization of disease patterns in HRCT images.

Abstract
Alzheimer's disease (AD) is the most common form of dementia diagnosed in people over 65 years of age. There is no cure for the disease, which worsens as it progresses, and eventually leads to death. As the disease advances, symptoms can include confusion, irritability and aggression, mood swings, trouble with language, and long-term memory loss. As the sufferer declines they often withdraw from family and society. Gradually, body functions are lost, ultimately leading to death. Current treatments only help with the symptoms of the disease. Following the vision of WHO and AD International for innovative approaches to AD, the system proposed here, namely Symbiosis, aims at creating a novel human-computer interaction (HCI) environment to facilitate, understand and incorporate the needs of the whole AD community (patients, caregivers and doctors). © 2013 Springer-Verlag Berlin Heidelberg.

Abstract
Information Systems (IS) and Technologies assume a wide variety of roles within companies, ranging from operational to strategic support of the company. This fact puts pressure on managers, who are required to manage these investments properly. This chapter presents a study conducted with several Chief Information Officers from large Iberian companies with the purpose of identifying and characterizing the roles played by IS and the motivations currently behind their adoption. The findings of this study reveal the reasons why IS and technologies are being adopted by Iberian companies are evolving and that, while the adoption of certain types of systems such as Enterprise Resource Planning systems is now consolidated, the adoption of other systems like Business Intelligence is expected to increase significantly in the near future.

Abstract
In an idea generation meeting, the facilitator role is essential to obtain good results. Also the emotional context of the meeting partially determines the (un) success of the meeting, being it of idea generation or decision selection. So the facilitator needs to obtain and process this information in order to assist the participants to reach their goals in different processes of decision making. In this paper is proposed a multi-agent framework able to be used in the support of persons in a affective context-aware and ubiquitous group decision process. Insights of the context-aware model are provided. It allows the gathering of certain typical variables of the affective context (emotions and mood) and transform those values in advises to the facilitator.
