Semi-metric Space: A New Approach to Treat Orthogonality and Parallelism
We propose a new method to recover 3D structures of artificial objects from scene pictures using orthogonality and parallelism. A new transformation group, “semi-metric space,” is defined to describe the scene...

Infinite Homography Estimation Using Two Arbitrary Planar Rectangles
In this paper, we propose a new method to estimate an infinite homography between two views containing two arbitrary planar rectangles. The proposed method does not require metric measurements, such as rectang...

Temperature fluctuations and heat transfer in a fluidized-bed combustor of waste oil
Temperature fluctuations and heat transfer characteristics were investigated in a fluidized-bed combustor of 0.102 m ID and 2.5 m in height, which was designed for waste oil combustion. Effects of excess air (AE)...

Promotion of CO2 hydrogénation to hydrocarbons in three-phase catalytic (Fe-Cu-K-Al) slurry reactors
A three-phase slurry reactor has been employed to increase the CO2 conversion and decrease the selectivity of CO in the direct hydrogénation of CO2 to hydrocarbons, as it is beneficial for removal of the heat gen...

Decomposition characteristics of residue from the pyrolysis of polystyrene waste in a fluidized-bed reactor
Effective treatment of residue generated from the pyrolysis of polystyrene wastes has been one of the important factors in the recovery of styrene monomer and oil from polystyrene wastes. Depending on the expe...

Hydrogenation of CO2 over Fe-K based catalysts in a fixed bed reactors at elevated pressure
Catalytic hydrogenation of CO2to produce hydrocarbons was conducted in a fixed bed reactor (1.6 cm-IDx60 cm-High). Fe-K based catalysts (KRICAT-A, B) were used for more than 850 hours to maintain CO2 conversion l...

Characteristics of carbon dioxide hydrogenation in a fluidized bed reactor
Characteristics of CO2 hydrogenation were investigated in a fluidized bed reactor (0.052 m IDxl.5 m in height). Coprecipitated Fe-Cu-K-Al catalyst (dρ=75–90 Μm) was used as a fluidized solid phase. It was found t...
