Experimental signatures of extreme optical fluctuations in lumped Raman fiber amplifiers
2012
International audience; In this work, we experimentally investigate several temporal and spectral methods to highlight extreme fluctuations which can develop during the Raman amplification of an ultrashort pulse train. Forward and backward pumping schemes are compared to dual pass configurations.

Disaster management in hospitals
1998
A disaster situation for a hospital occurs when the need for medical treatment overwhelms the actual hospital treatment capacity. 1 This may be defined by numerical or situational means; the threshold must always be the result of an individual assessment of the given health care unit. A disaster situation may also be defined as the point of no return to normal standard operating procedures in a certain hospital. In case of a disaster, health care units are required to have and activate a disaster management plan (DMP). In the USA the requirements of the Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) are trend-setting; in European countries, regulations are normall…
Experimental demonstration of an ultrafast all-optical bit-error indicating scheme
2010
International audience; We experimentally demonstrate an all-optical bit error monitoring scheme based on the self-phase modulation occurring during the propagation in a highly nonlinear fiber followed by an optical bandpass filter. Numerical simulations are confirmed by experimental observations performed at a repetition rate of 40 Gb/s.
MULTIBODY NUMERICAL SIMULATION FOR VEHICLE – PEDESTRIAN CRASH TEST
2009
The purpose of this paper is the simulation of vehicle – pedestrian crash test, executed by Visual Nastran. The evaluation of the damage caused to pedestrian is obtained following the EURONCAP directive. The vehicle virtual model, DIMA, follows closely the characteristics of a saloon car belonging to the small cars category. A total of 16 simulation tests are conduced; each characterized by different initial conditions. The vehicle advances with several speeds, at constant speed and in braking. The anthropomorphic model Dummy impacts with the vehicle in lateral or perfectly frontal position with respect to the front of the vehicle.
EFFICACY OF ARGENTUM-QUARTZ SOLUTION IN THE TREATMENT OF PERIANAL FISTULAS: A PRELIMINARY STUDY
2015
Objective: Nowadays, an optional and effective medical surgery remains the gold standard for perianal fistulas. Hereby we reported preliminary rsults in favor of using Argentum-Quartz solution for both primary and recurrent perianal fisrtulas. Methods: Three patients with intersphimncter and extrasphinteric fistulas were enrolled. Argentum-Quartz solution was administrated twice a week for sa period of 4 weeks, followed by a pause of 8 days and then another 4 weeks of treatment, totally 16 administrations. After treatment, all patients were monitored for 4-months follow-up. Results: Complete closures of 2 extrasphinteric fistulas and a partial closure with absence of inflammation and supera…
Maculopapular rash and fever: a diagnostic challenge to the paediatrician in the COVID-19 pandemic
2021
Introduction: Several clinical conditions can manifest with fever and a maculopapular rash in paediatric age. Although some presentations are benign, others may be medical emergencies, which demand a prompt diagnosis and treatment. Some of the more common causes of fever and maculopapular rash include infectious diseases (Sars-CoV-2, Parvovirus B19; Coxsackie; Epstein-Barr virus infection, Mycoplasma Pneumoniae, etc), hypersensitivity reactions, Autoinflammatory syndromes, vasculitis, Kawasaki disease (KD), autoimmune diseases. Objectives: In the COVID-19 pandemic era these symptoms need a well-organized hospital strategy to rapidly exclude Sars-CoV-2 infection and to distinguish severe and…
Signal reconstruction, modeling and simulation of a vehicle full-scale crash test based on Morlet wavelets
2012
Creating a mathematical model of a vehicle crash is a task which involves considerations and analysis of different areas which need to be addressed because of the mathematical complexity of a crash event representation. Therefore, to simplify the analysis and enhance the modeling process, in this paper a novel wavelet-based approach is introduced to reproduce acceleration pulse of a vehicle involved in a crash event. The acceleration of a colliding vehicle is measured in its center of gravity-this crash pulse contains detailed information about vehicle behavior throughout a collision. Three types of signal analysis are elaborated here: time domain analysis (i.e. description of kinematics of…
Physical modelling of the melt flow during large-diameter silicon single crystal growth
2003
Abstract The reported investigations concern physical modelling of Czochralski growth of silicon large-diameter single crystals. InGaSn eutectic was used as a modelling liquid, employing actual criteria of the real process (Prandtl, Reynolds, Grashof numbers, etc.) and geometric similarity. A multi-channel measuring system was used to collect and process the temperature and flow velocity data. The investigations were focused on the study of heat transfer, in particular, the instability of the “cold zone” of the melt at the crystallization front.
