In this paper we present our teamwork main results in the area of the automatic speech recognition and understanding in Romanian language using hidden Markov models (HMM), artificial neural networks (multilayer perceptron, support vector machines, Kohonen networks) and hybrid models (fuzzy HMM, fuzzy multilayer perceptron, HMM/multilayer perceptron) for different small Romanian language corpora...

Synthesis of multilayer graphene on copper wires by a chemical vapor deposition method is reported. After copper etching, the multilayer tube collapses forming stripes of graphitic films, their electrical conductance as a function of temperature indicate a semiconductor-like behavior. Using the multilayer graphene stripes, a cross junction is built and owing to its electrical behavior we propos...

We present a new security technology called the Multilayer Firewall. We argue that it is useful in some situations for which other approaches, such as cryptographically protected communications, present operational or economic difficulties. In other circumstances a Multilayer Firewall can compliment such security technology by providing additional protection against intruder attacks. We first p...

Multilayer rectangular dissections have been considered such as models of multi page books in spreadsheets, 3D floor plans and stratum maps in terrain surfaces. In this paper, we deal with a representation of the multilayer rectangular dissections that are effective for ruled line oriented operations and introduce hexadecimal grids corresponding to multilayer rectangular dissections. And we sho...

in this study, in order to constitute polyelectrolyte multilayers (pem) using layer-by-layer nanotechnology, recycled fibers were subsequently treated with cationic starch (cs) and anionic starch (as) multi-layers each layer conducted at neutral ph for 10 minutes. also, to compare with mechanical of refining, the pulp was refined for 25 minutes to the freeness of about 291 ml.csf using valley b...

OBJECTIVES (i) To evaluate the role of the adherent growth mode and extracellular polymer substance build-up in biofilm resistance to antibiotics. (ii) To re-assess various mechanisms leading to biofilm resistance to antibiotics. METHODS We compared the biofilm MICs, biofilm MBCs using the viable count method, biofilm MBCs based on broth recovery methods and minimum biofilm eradication concen...

A new broadband in-phase power divider based on multilayer technology is presented. A simple design procedure is developed for the proposed multilayer power divider. An S-band four-way multilayer power divider was designed and measured. The simulated results are compared with the measured data, and good agreement is reported. The measured 15 dB return loss bandwidth is demonstrated to be about ...

In most natural and engineered systems, a set of entities interact with each other in complicated patterns that can encompass multiple types of relationships, change in time and include other types of complications. Such systems include multiple subsystems and layers of connectivity, and it is important to take such ‘multilayer’ features into account to try to improve our understanding of compl...

Metal–dielectric multilayer metamaterials with extreme loss-anisotropy, in which the longitudinal component of the permittivity tensor has an ultra-large imaginary part, are proposed and designed. Diffraction-free deep subwavelength beam propagation and manipulation, due to the nearly flat iso-frequency contour, is demonstrated in such loss-anisotropic metamaterials. It is also shown that deep ...
