Quilombola communities are present in many Brazilian states living in precarious health conditions. This is due to geographic isolation, limitations to the access of the area in which they live in, and the lack of quality in the service when it is needed to be provided. Therefore, the aim of this study was to analyze the quality of life of women from a quilombola community in northeastern Brazil.

Until the end of 1997, governmental accounting in Portugal was characterised as essentially cash-based budgetary accounting, using singleentry as the bookkeeping method. The only compulsory accounting system was Budgetary Accounting. As many countries all over the world, nowadays Portugal is implementing a reform of the whole governmental accounting, which has as most important innovations the use of double-entry within a system compulsorily integrating accrual-based Financial and Cost Accounting ...

However, there have been criticisms of NPM, particularly over its emphasis on quantification, results orientation and the measurement of performance to the possible detriment of service delivery. The purpose of this paper is to examine an important public service – the fire service – in differing contexts: the “mature” NPM setting of the UK, and a “late adopter” of NPM – Portugal.

The inverse dynamic analysis procedures used in the study of the human gait require that the kinematics of the supporting biomechanical model is known beforehand. The first step to obtain the kinematic data is the reconstruction of human spatial motion, i.e., the evaluation of the anatomic points positions that enables to uniquely define the position of all anatomical segments. In photogrammetry, the projection of each anatomical point is described by two linear equations relating its three spatial ...

The application of model predictive control (MPC) to complex, nonlinear processes results in a non-convex optimization problem for computing the optimal control actions. This optimization problem can be solved by discrete search techniques such as the branch-and-bound method (B&B), which has been successfully applied to MPC. However, the discretization induced by B&B introduces a tradeoff between the number of discrete actions and the performance. This paper proposes a solution for non-convex optimization ...

However, the implementation of meta-heuristics is done only after a positive assessment of the performance's expectation provided by the fitness- ...

The FTC approach is based on two steps, fault detection and isolation (FDI) and fault accommodation. The fault detection is performed by a model-based approach using fuzzy modeling and fault isolation uses a fuzzy decision making approach. The information obtained on the FDI step is used to select the model to be used in fault accommodation, in a model predictive control (MPC) scheme. The fault accommodation ...
