This study aims to investigate the role of intonation in the perception of emotion in spoken Brazilian Portuguese (BP). Recordings of 32 BP speakers were downloaded from the internet and presented to 36 listeners divided equally into two nationality groups (Brazilian vs. English). The participants performed two perception experiments, one based on normal speech and the other on delexicalised (l...

In this article we introduce a new method to construct finite orthogonal quadrature filters using convolution kernels. We show that every filter with value 1 at the origin can be obtained using an even nonnegative kernel. We apply the method to estimate the optimal frequency localization of finite filters. The frequency localization γp of a finite filter m0 is given by the distance in L p-norm ...

One compact microstrip low-pass filter using conventional elliptical headed dumbbell shaped

The human auditory system is insensitive to phase information of the speech signal. By taking advantage of this fact data such as the transcript, some keywords, and copyright information can be embedded into the speech signal by altering the phase in a prede ned manner. In this paper, an all-pass ltering based data embedding scheme is developed for speech signals. Since all-pass lters modify on...

brain-computer interfaces (bci) record brain signals, analyze and translate them into control commands which are relayed to output devices that carry out desired actions. these systems do not use normal neuromuscular output pathways. actually, the principal goal of bci systems is to provide better life style for physically-challenged people which are suffered from cerebral palsy, amyotrophic la...

In this paper using the critical point theory of Chang [4] for locally Lipschitz functionals we prove an existence theorem for noncoercive Neumann problems with discontinuous nonlinearities. We use the mountain-pass theorem to obtain a nontrivial solution.

This paper aims to show the existence of nontrivial solutions for discrete elliptic boundary value problems by using the “Mountain Pass Theorem”. Some conditions are obtained for discrete elliptic boundary value problems to have at least two nontrivial solutions. The results obtained improve the consequences of the known literature [Guang Zhang, Existence of nontrivial solutions for discrete el...
