The increasingly complex business environment necessitates businesses to design more effective and efficient strategies for company development, including market expansion. To understand customer behaviors, data analysis becomes crucial. One common approach used group customers is segmentation based on RFM (Recency, Frequency, Monetary). This study aims compare the performance of two clustering...

We investigate weakly-supervised image parsing, i.e., assigning class labels to image regions by using imagelevel labels only. Existing studies pay main attention to the formulation of the weakly-supervised learning problem, i.e., how to propagate class labels from images to regions given an affinity graph of regions. Notably, however, the affinity graph of regions, which is generally construct...

in this work, experimental kinetics data of methane hydrate decomposition at temperatures ranging from 272.15 to 276.15 k and at pressures ranging from 10 to 30 bars were modeled by using chemical affinity. this model proposed a macroscopic model which is independent of any intermediate mechanism like heat or mass transfer. the results show there is good agreement with experimental data. also t...

in this study escherichia coli de3 containing expression vector (pet21a) with cloned persian sturgeon growth hormone (psgh) gene was grown in 10 ml lb broth on a 150 rpm shaker, at the temperature of 37 °c. at the late log phase (determined by od standard curve) 100 μl isopropyl β-d-1-thiogalactopyranoside (iptg) was added for induction of gh synthesis. samples were taken every 2 hours and afte...

the purification of biomolecules is a necessary step in many biochemical researches. in this regard, developments of convenient, specific and low cost methods of purification are of particular interest. given the human hemoglobin (hb) affinity toward some charged carbohydrates, interaction of this molecule with human chorionic gonadotropin (hcg) which is a glycoprotein hormone containing sialic...
