Aims/ Objectives: Today, the interest in brain and computer interfaces has rapidly grown owing to the possibility of providing disabled subjects with new communication channels. Despite these interests, there are some obstacles in providing applicable BCIs. One of these obstacles is the non-stationary nature of brain signals varying from trial-to-trial and subject-to-subject. To overcome this problem, we need to design dynamic systems to adapt them to this data. Methodology: In this paper, we propose a dynamic classifier-based brain emotional learning (DCBEL) for P300 based BCIs. This algorithm, by inspiration of brain emotional learning system, provides a dynamic system which is able to deal with non-stationary nature of brain signals. The application of the proposed method in P300 based BCIs is done for the first time. We test this system, on 4 able-bodied and 4 disabled subjects. Results: The results showed classification accuracy of 95.39 for disabled and 93.27 for able-bodied. Conclusion: The comparison of our results with two other algorithms multilayer perceptron and fuzzy inference system proves the superiority of our proposed algorithm.
A set of non-standard discrete models are constructed for the solution of non-homogenous second order equation. The method of non-local approximation and renormalization of the discretization functions have been applied to some examples and the result has shown that the schemes behave qualitatively like the original equation.
The paper introduces ultra-wideband (UWB) antenna for WPAN application with reduced ground plane size. This paper proposes a hexagonal antenna with microstrip feed line. The proposed antenna with small size and different ground structure is considered to reduce the surface wave and to achieves high impedance bandwidth and good gain performance for ultra wide band (UWB) range i.e. 3.1–10.6 GHz. Three variations of the antenna design by using different ground size, shape such as rectangular, semicircle, circular and two different substrates are considered. Return losses are considered satisfactory below -10 dB and VSWR considered being well if it is below 2. In last section the return loss performance of fabricated antenna is measured and it shows agreement with the simulated data with little variation.
For any 0 < δ < 1 there exists a measurable function μ(x), 0 < μ(x) ≤ 1, with | {x ∈ [0, 1]; μ(x) ≠ 1} |< δ, and a series in the Walsh system of the form
such that for any p ≥ 1 and any function one can fined subseries of above series converging
In this paper, we prove the existence of fixed points and demiclosed principle for total asymptotically nonexpansive mappings in hyperbolic spaces. As a consequence, we obtain a Δ-convergence theorem for such mappings in hyperbolic spaces. Our results improve and extend some results in the literature.
Considerable interest in this article is to introduce the sequence space derived by generalized difference Fibonacci matrix in which r,s ∈ \ {0}, also to discuss and compare with some wellknown spaces defined previously. In addition to those, after demonstrating that the spaces and bc are linearly isomorphic, we have determined the β— and γ—duals of space and have characterized some matrix classes on this space. As a conclusion, we have also found out that the space has not a Schauder basis. Lastly, we have presented the Fibonacci core of a complex-valued sequence and deal with inclusion theorems with respect to Fibonacci core type.
