Dissertação apresentada para obtenção do Grau de Doutor em Engenharia do Ambiente, ABSTRACT Genetic algorithms (GAs) have been used to solve difficult optimization problems in a number of fields. One of the advantages of these algorithms is that they operate well even in domains where little is known, thus giving the GA the flavor of a general purpose(More)
Pulsed Arterial Spin Labeling (PASL) techniques potentially allow the absolute, non-invasive quantification of brain per-fusion using Magnetic Resonance Imaging (MRI). This can be achieved by fitting a kinetic model to the data acquired at a number of inversion times (T I). Some model parameters such as the arterial transit time need to be estimated(More)
The aim of this study was to advance understanding of how clients construct their own process of change in effective therapy sessions. Toward this end, the authors applied a narrative methodological tool for the study of the change process in emotion-focused therapy (EFT), replicating a previous study done with narrative therapy (NT). The Innovative Moments(More)
Previous studies have used the Innovative Moments Coding System (IMCS) to describe the process of change in Narrative Therapy (NT) and in Emotion-Focused Therapy (EFT). This study aims to extend this research program to a sample of Client-Centered Therapy (CCT). The IMCS was applied to six cases of CCT for depression to track the Innovative Moments (IMs)(More)
In many longitudinal studies, the outcomes recorded on each subject include both a sequence of repeated measurements at pre-specified times and the time at which an event of particular interest occurs: for example, death, recurrence of symptoms or drop out from the study. The event time for each subject may be recorded exactly, interval censored or right(More)
Innovative moments (IMs) are exceptions to a client's problematic self-narrative in the therapeutic dialogue. The innovative moments coding system is a tool which tracks five different types of IMs-action, reflection, protest, reconceptualization and performing change. An in-depth qualitative analysis of six therapeutic cases of emotion-focused therapy(More)
Falls are considered the main cause of fear and loss of independence among the elderly population and are also a major cause of morbidity, disability and health care utilization. In the majority of fall events external support is imperative in order to avoid major consequences. Therefore, the ability to automatically detect these fall events could help(More)
Prior work has demonstrated the integration of detailed life-cycle assessment into a traditional design modeling process. While a full life-cycle assessment provides insight into a product's potential impact on the environment, it is often too time consuming for analysis during conceptual product design, where ideas are numerous and information is scarce.(More)
OBJECTIVE Dialysis is the most common renal replacement therapy for patients with end stage renal disease. This paper considers survival of dialysis patients, aiming to assess quality of renal replacement therapy at dialysis centers in Rio de Janeiro, Brazil, and to investigate differences in survival between health facilities. METHODS A Cox proportional(More)
Monitoring physical activity and energy expenditure is important for maintaining adequate activity levels with an impact in health and well-being. This paper presents a smartphone based method for classification of inactive postures and physical activities including the calculation of energy expenditure. The implemented solution considers two different(More)
