Enhancing Classification Performance Using Attribute-oriented Functionally Expanded Data
(Elsevier Science BVAmsterdam, 2017)
Exploring the potential of functionally graded materials concept for the development of fiber cement
(ELSEVIER SCI LTD, 2010)
In this study we establish the concept of functionally graded fiber cement. We discuss the use of statistical mixture designs to choose formulations and present ideas for the production of functionally graded fiber cement ...
Balance, executive functions and falls in elderly with Alzheimer's disease (AD): A longitudinal study
(Elsevier B.V., 2012-03-01)
Elderly individuals with AD are more susceptible to falls, which might be associated with decrements in their executive functions and balance, among other things. We aimed to analyze the effects of a program of dual task ...

Effect of different exercise programs on the psychological and cognitive functions of people with Parkinson's disease
(2013-01-01)
The purpose of this study was to analyze the effect of different exercise programs on the psychological and cognitive functions in patients with Parkinson's disease (PD). Forty-five patients with PD participated in the ...
On the Green's function for the Helmholtz operator in an impedance circular cylindrical waveguide
(ELSEVIER, 2010)
This paper addresses the problem of finding a series representation for the Green's function of the Helmholtz operator in an infinite circular cylindrical waveguide with impedance boundary condition. Resorting to the Fourier ...
Computer task performance by subjects with Duchenne muscular dystrophy
(Dove Medical Press Ltd, 2016)
Aims: Two specific objectives were established to quantify computer task performance among people with Duchenne muscular dystrophy (DMD). First, we compared simple computational task performance between subjects with DMD ...
Functional vision barriers: a new concept analyzed in terms of human visual performance
(Universidad de Río de Janeiro, 2013-11)
In this work we introduce a new category of barriers that we call "functional vision barriers." This expression refers to lighting and visual elements that may complicate or hinder functional vision and may make life even ...
Performance enhancement of switched affine systems by switched quadratic Lyapunov functions: Applications in DC-DC converters
(2013-01-01)
This paper proposes design methodologies to include the convergence rate to Switched Affine Systems, intending to reduce the current overshoot in DC-DC converters. The initial step consists in finding Lyapunov matrices for ...
