The design of future multi-standard systems is very challenging. Flexible architectures exploiting processing commonalities of the different set of standards cohabiting in the device offer promising solutions. This paper presents a graphical approach for the optimization of multi-standard Software Defined Radio (SDR) systems. The potential of our approach for optimizing multi-standard SDR syste...

This paper proposes a totally multiplier-less approximate reconstruction cosine modulated filter bank. The prototype filter is designed to obtain a computationally efficient, sharp transition width, finite impulse response (FIR) filter using the frequency response masking (FRM) approach combined with the canonic signed digit (CSD) representation of the coefficients. Meta-heuristic algorithms ar...

this paper investigates the stability analysis of fuzzy relational dynamic systems. a new approach is introduced and a set of sufficient conditions is derived which sustains the unique globally asymptotically stable equilibrium point in a first-order fuzzy relational dynamic system with sumproduct fuzzy composition. this approach is also investigated for other types of fuzzy relational composit...

We propose and experimentally demonstrate a continuous wave (CW) tunable-wavelength fiber laser using self-seeding Fabry-Perot laser diode (FP-LD) without optical amplifier inside gain cavity. By employing a tunable bandpass filter (TBF) and a fiber reflected mirror (FRM) within a gain cavity, the fiber laser can lase a single-longitudinal wavelength due to the self-seeding operation. The propo...

In [11] we met the notions of a frame and a frame morphism. These form the objects and arrows of the category Frm . We saw that the universal algebra of a frame A is best done using certain operators on A, the nuclei on A. The collection NA of all these, the assembly of A, is partially ordered by the pointwise comparison. In fact, NA is a complete lattice since it is closed under pointwise infi...

Existing space-time video super-resolution (ST-VSR) methods fail to achieve high-quality reconstruction since they fully explore the spatial-temporal correlations, long-range components in particular. Although recurrent structure for ST-VSR adopts bidirectional propagation aggregate information from entire video, collecting temporal between past and future via one-stage representations inevitab...

Abstract Thermochromic materials change their optical response to temperature reversibly. This study explores the application of thermochromism road engineering, which is still incipient in this area, from two perspectives. The first one about development functionalized markings (FRM) working as thermochromic sensors alert presence ice on and, way, improve safety. second concerns functionalizat...

Abstract Flooding is an important global hazard that causes average annual loss of over 40 billion USD and affects a population 250 million globally. The complex process flooding depends on spatial temporal factors such as weather patterns, topography, geomorphology. In urban environments where the landscape ever-changing, ground cover, green spaces, drainage systems have significant impact. Un...
