Near-duplicate image detection is a necessary operation to refine image search results for efficient user exploration. The existences of large amounts of near duplicates require fast and accurate automatic near-duplicate detection methods. We have designed a coarse-to-fine near duplicate detection framework to speed-up the process and a multi-modal integration scheme for accurate detection. The...

We study the nodal set of the Steklov eigenfunctions on the boundary of a smooth bounded domain in Rn – the eigenfunctions of the Dirichlet-to-Neumann map Λ. For a bounded Lipschitz domain Ω ⊂ Rn, this map associates to each function u defined on the boundary ∂Ω, the normal derivative of the harmonic function on Ω with boundary data u. Under the assumption that the domain Ω is C2, we prove a do...

The effect of polyelectrolytes; cationic and anionic charges and coagulants have been investigated for fresh activated sludge at different concentrations and pH values in a comparative fashion. The results from the experiments indicate that the cationic polyelectrolytes have a significant effluence on the sludge characteristic, degree of flocculation and water quality such as turbidity and SVI....

UNLABELLED Congenital cystic adenomatoid malformation (CCAM), also named congenital pulmonary airway malformation (CPAM), is a congenital abnormality of lung which is uncommon in adults. Here we present 2 adult cases of CCAM with unusual clinical and pathologic findings. One case was complicated with aspergillosis which was seldom reported. The other case was suffered bilateral lesions and the ...

The appropriate pitch control is critical in many pulp and paper operations. One of the important approaches for pitch control is to use synthetic polymers. In this paper, we provide evidence from differential scanning calorimetry (DSC) analysis that the pitch deposits formed with polymers, such as polyDADMAC and CPAM, had better thermal stability than those without these polymers. Metal cation...

Palm oil mill effluent (POME) is considered the most environmentally harmful when discharged without proper treatment. In addition to conventional biological treatment methods, physicochemical techniques are alternative methods treat POME as polishing or post-treatment meet discharge water quality standards set by authorities. Recently, electroflotation (EF) has gained popularity in wastewater ...

A new synergetic flame retardant system (SFRS) using ammonium polyphosphate/melamine cyanurate (APP/MCA) core-shell particle was synthesized and applied to papermaking. Cationic polyacrylamide (CPAM) was added to improve the adsorption of SFRS in pulp. Higher amounts of SFRS led to higher adsorption by pulp. Handsheets were produced with different amounts of SFRS. Thermal gravimetric analysis (...

UNLABELLED In adults, congenital pulmonary malformations are candidates for surgery due to symptoms. A pre-natal diagnosis is simple and effective, and allows an early thoracoscopic surgical treatment. A retrospective study was performed to assess management in two different populations of adults and children to define the best strategy. SUBJECTS AND METHODS Pulmonary malformations followed a...
