In this paper, we present a new approach for improving the robustness of automatic speech recognition systems to additive noise. This approach lies on the use of a particular training procedure (based on data contamination) in a particular architecture (the multi-band paradigm). In this framework, we expect to remove the drawbacks of both the corpus contamination approach which is the dependenc...

Multiband bandpass filters (BPFs) and multiplexers are essential front-end modules in the development of multifunction, multistandard, multiband wireless communication, sensing, positioning systems that required current future intelligent electronics applications. In this paper, numerous implementation schemes topologies BPFs multiplexers, which have been proposed, studied, developed so far, ho...

Topology and geometry are essential to our understanding of modern physics, underlying many foundational concepts from high-energy theories, quantum information, and condensed-matter physics. In condensed-matter systems, a wide range of phenomena stem from the geometry of the band eigenstates, which is encoded in the matrix-valued Wilson line for general multiband systems. Using an ultracold ga...

Sierpinki gasket antennas as example of fractal antennas show multiband characteristics. The computer simulation of Sierpinksi gasket monopole with finite ground needs prohibitively large computer memory and computational time. Hybrid methods consist of surface integral equation method and physical optics or uniform geometrical theory of diffraction is expected to alleviate this computational b...

Software defined radar (SDR) is a multi-purpose radar system where most of the hardware processing is performed by software. This paper introduces a concept and technology trends of software defined radar, and addresses the advantages and limitations of the current SDR radar systems. For the advanced SDR concept, the KAU SDR Model (KSM) is presented for the multimode and multiband radar system ...

The discovery of multiband afterglows definitely shows that most γ-ray bursts are of cosmological origin. γ-ray bursts are found to be one of the most violent explosive phenomena in the Universe, in which astonishing ultra-relativistic motions are involved. In this article, the multiband observational characteristics of γ-ray bursts and their afterglows are briefly reviewed. The standard model ...

We consider the decoding of bit interleaved coded modulation (BICM) applied to both multiband and MIMO OFDM systems for typical scenarios where only a noisy (possibly very bad) estimate of the channel is provided by sending a limited number of pilot symbols. First, by using a Bayesian framework involving the channel a posteriori density, we adopt a practical decoding metric that is robust to th...

"Multiband transmission calculations for nanowires using an optimized renormalization method" (2008). The discovery of an interesting nanostructure behavior or the design of useful nanodevices requires state-of-the-art physical models. Realistic, multiband nanowire calculations especially tend to be computationally intensive and slow. Here, we develop optimizations to the renormalization method...

We report a multiband transport study of bilayer graphene at high carrier densities. Employing a poly(ethylene)oxide-CsClO4 solid polymer electrolyte gate we demonstrate the filling of the high-energy subbands in bilayer graphene samples at carrier densities |n| 2.4 × 1013 cm−2. We observe a sudden increase of resistance and the onset of a second family of Shubnikov–de Haas (SdH) oscillations a...
