Faster-than-Nyquist (FTN) signaling is a promising non-orthogonal pulse modulation technique that can improve the spectral efficiency (SE) of next generation communication systems at expense higher detection complexity to remove introduced inter-symbol interference (ISI). In this paper, we investigate problem ultra high-order quadrature-amplitude (QAM) FTN where exploit mathematical programming...

ELECTRONIC Noses (EN), in the broadest meaning, are instruments that analyze gaseous mixtures for discriminating between different (but similar) mixtures and, in the case of simple mixtures, quantify the concentration of the constituents. ENs consists of a sampling system (for a reproducible collection of the mixture), an array of chemical sensors, Electronic circuitry and data analysis softwar...

A little over a decade ago, passive humidifiers, ¦^^ commonly called "artificial noses," were rele¬ gated to short-term use, typically less than 24 h. Improvements in design, coupled with careful clini¬ cal investigations, have proven that in select patients, passive humidifiers can be used safely for several days.15 The definition oi several is currently debat¬ able, but evidence for up to 5 d...

investigating the frequency of traumatic nasal bone fracture in patients with and without old septal deviation and possible deviation. prospective study of 105 patients with nose trauma conducted and cases were divided into two groups: a study group 35 patients with nasal fracture and a control group of 70 patients without nasal fracture. diagnosis of septal condition was made by anterior rhino...
