feel that the results we show, particularly in Figure 6, are on much more complex examples and that we have processed much larger number of buildings than reported in the previous literature ([5], [2], and [9]). We feel that our method has advantage over monocular systems such as ([5]) due to its ability to infer 3-D more directly and of having several views to validate the hypotheses. We feel ...

in the present study, modelling and vibration analysis of carbon nanotubes/ fiber/ polymer composite microplates are investigated. the governing equations of the carbon nanotubes/ fiber/ polymer composite microplates are derived based on first order shear deformation plate theory, rather than other plate theories, due to accuracy and simplicity of polynomial functions. the modified couple stres...

Extended Abstract Introduction: Iranian oak has the largest forest habitat in the country and has a high position in terms of economy and protection. Recent studies have confirmed the positive effects of carbon nanotubes on the germination and organ growth of herbaceous and woody species. Nanotechnology is an evolving field in all periods of human life and various research is done to use nanom...

Banana pith was used as precursor material to prepare carbon with and without porogens. Characterization of the carbons showed higher BET surface area (1285 m2/g) for ZnCl2-treated carbon, comparatively. Adsorption experiments were conducted to study the removal of 2,4-dichlorophenol (DCP) from aqueous solutions using the carbons under varying experimental conditions. Decrease in pH increased t...

An important parameter in composite materials is mechanical behavior and matrix-reinforcement interface interaction under applied stresses. In this investigation, bending strength of carbon-carbon composites synthesized from wood was analyzed as a measure of the composite mechanical properties. Also, densification efficiency of the products was determined by measuring the bulk density and open ...

Temperate symbiotic corals, such as the Mediterranean species Cladocora caespitosa, live in seasonally changing environments, where irradiance can be ten times higher in summer than winter. These corals shift from autotrophy in summer to heterotrophy in winter in response to light limitation of the symbiont's photosynthesis. In this study, we determined the autotrophic carbon budget under diffe...
