Communication system recognition can be used in some civilian and military applications. The recognition of the system is done by inspecting the received signal properties like modulation type, carrier frequency, baud rate and so on. Therefore we need Automatic Modulation Recognition (AMR) in addition to carrier and baud rate estimation methods. In this paper we introduce a new AMR method based...

A total of 342 men from both the Blue and Gold crews of the Polaris submarine USS MARIANO G. VALLEJO (SSBN-658), were surveyed periodically over a 13-month period for the causative organism of meningitis (Neisseria meningitidis). It was found that the overall carrier rate was 26 percent, with four percent chronic carriers, 28 percent always negative, and 68 percent intermittent carriers. Of all...

The UNSW node of the Hot Carrier Solar Cell project is investigating absorbers which slow the rate of carrier cooling an essential element of a successful cell. This work includes modelling the limiting efficiencies of cells using real material properties and modelling the phonon dispersions of ordered arrays of quantum dots. The object of the latter is to determine the potential to modify the ...

PURPOSE The purpose of this study was to prepare and characterize solid dispersion formulation of furosemide to enhance dissolution rate. METHODS Solid dispersions with different drug: carrier ratios were prepared by cogrinding method using crospovidone and microcrystalline cellulose as carrier. The physical state and interactions between the drug and carrier were characterized by Fourier tra...

BACKGROUND This systematic review aimed to evaluate the clinical performance of core-carrier obturation in endodontic treatment. METHODS Keywords of "(core carrier OR Thermafil) OR (cold lateral condensation OR lateral condensation) OR (warm vertical condensation OR vertical condensation) AND (obturation OR root canal filling) AND clinical study" were searched for all obtainable publications ...

in this paper, we consider a cooperative cognitive radio network in which there is an ofdm primary link and multiple single carrier secondary links.the primary link is required to maintain its secrecy rate above a predefined threshold. if the secrecy rate requirement is not satisfied, the secondary system help primary link to maintain its secrecy rate requirement. in doing so, the secondary trans...

Solute uptake by a mobile carrier me&a&m has been simulated with an analog computer for the case where the movement of the carrier across the membrane is rate-limiting. The ratio of the rate constants for the translccation of the loaded carrier to those for the translocation of the empty carrier was varied to simulate three important conditions of transport: a ratio greater than unity, which le...

We have investigated the quantum dot (QD) carrier capture mechanism using continuous wave photoluminescence as a function of the optical excitation intensity using a sample with a QD density gradient across its surface ranging from 0 to 1.8 £ 10 cm. Modelling of the carrier kinetics has been described by a set of three coupled rate equations associated with the carrier population in the GaAs ba...

The purpose of this study was to develop and evaluate the flow rate, spray pattern, and droplet spectra characteristics of an actively controlled variable-orifice nozzle at constant carrier pressures. A commercially available variable-orifice nozzle (VariTarget) was modified to allow for direct electromechanical control of the metering stem. The modified system was tested at five carrier pressu...

Objective(s): Researchers have intended to reformulate drugs so that they may be more safely used in human body. Polymer science and nanotechnology have great roles in this field. The aim of this paper is to introduce an efficient drug delivery vehicle which can perform both targeted and controlled antibiotic release using magnetic nanoparticles grafted pH-responsive polymer.<s...
