Experimental investigation on the scintillation index of vortex beams propagating in simulated atmospheric turbulence
Experimental investigation scintillation index vortex beams propagating simulated atmospheric turbulence
2013/7/3
The scintillation index of vortex beam in simu-lated atmospheric turbulence is experimentally investigated.The fluctuation of the intensity can be effectively reduced by vortex beams. In particular, t...
Experimental investigation on partially coherent higher-order non-diffractive beams
physical optics higher-order non-diffractive Bessel beam axicon partially coherence
2013/7/3
We experimentally study the generation of a partially coherent non-diffractive beam by focusing a partially coherent vortex beam with an axicon. The investigation results show that when the partially ...

Experimental investigation the predictive capabilities data driven modeling techniques
2010/12/22
A comprehensive data driven modeling experiment is presented in a two-part paper. In this first part, an extensive data-driven modeling experiment is proposed. The most important concerns regarding th...
An experimental investigation for external RC shear wall applications
An experimental investigation external RC shear wall applications
2010/10/21
The strength and rigidity of most reinforced concrete (RC) buildings in Turkey, which are frequently hit by destructive earthquakes, is not at a sufficient level. Therefore, the result of earthquakes ...
Experimental investigation on steady granular flows interacting with an obstacle down an inclined channel: study of the dead zone upstream from the obstacle. Application to interaction between dense snow avalanches and defence structures
Experimental investigation steady granular flows the dead zone upstream dense snow avalanches defence structures
2009/12/9
An experimental investigation with dry granular flows passing over an obstacle down a rough inclined channel has been performed. The aim is to improve our understanding of the interaction between dens...
Experimental investigation of homogeneous freezing of sulphuric acid particles in the aerosol chamber AIDA
homogeneous freezing sulphuric acid particles aerosol chamber AIDA
2009/3/10
The homogeneous freezing of supercooled H2SO4/H2O solution droplets was investigated in the aerosol chamber AIDA (Aerosol Interactions and Dynamics in the Atmosphere) of Forschungszentrum Karlsruhe. 2...
Ozone decomposition on Saharan dust: an experimental investigation
Ozone decomposition Saharan dust experimental investigation
2009/3/10
The heterogeneous reaction between O3 and authentic Saharan dust surfaces was investigated in a Knudsen reactor at approx 296 K. O3 was destroyed on the dust surface and O2 was formed with conversion ...
Experimental Investigation of Wave Breaking Criteria Based on Wave Phase Speeds
Experimental Investigation Wave Breaking Criteria Wave Phase Speeds
2008/6/6
Experiments were performed that test the kinematic breaking criterion, which states that the horizontal fluid particle velocity at the surface of a crest exceeds the local phase speed of the crest pri...

Experimental investigation of taxon-specific response of alkaline phosphatase activity in natural freshwater phytoplankton
taxon-specific response alkaline phosphatase activity natural freshwater phytoplankton
2014/5/20
It is widely accepted that alkaline phosphatase activity (APA) is an efficient indicator of phosphate limitation in freshwater phytoplankton communities. In this study, we investigated whether the res...
Experimental Investigation of Temperature Effect on Refractive Index of Dye Laser Liquids
Temperature Effect Refractive Index Dye Laser Liquids
2010/4/13
In this work, refractive index of selected dye laser solutions were measured by fiber optic sensor. The fiber optic probe was dipped into the liquids and according to Fresnel's Reflection Law, refract...
