Chemical modification of naturally occurring polysaccharide, guaran has been made by incorporating 5aminosalicylic hydroxamate moiety to improve its selectivity and capacity for heavy metal ions. 5Amino salicylic acid hydroxamate derivative of guaran (ASAH-G) was synthesized, characterized and its adsorption behavior with Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), U(VI), W(VI), Cr(VI) and ...

the present study was carried out to evaluate three interpolation methods including weighted moving average (wma) with the power of 2 and 3, kriging and cokriging methods. data of 23 wells in mazandaran province were collected in fall and spring 2006. seven parameters including electrical conductivity (ec), ph, total dissolved solids (tds), sodium adsorption ratio (sar), total hardness (th), ch...

This letter presents an effective data-driven anomaly detection scheme for automatically recognizing unbalanced sitting posture in a wheelchair using data from pressure sensors embedded the wheelchair. Essentially, designed approach merges desirable features of kernel principal component analysis (KPCA) as feature extractor with Kantorovich distance (KD)-driven monitoring chart to detect abnorm...

Compared with the feature-based distillation methods, logits can liberalize requirements of consistent feature dimension between teacher and student networks, while performance is deemed inferior in face recognition. One major challenge that light-weight network has difficulty fitting target due to its low model capacity, which attributed significant number identities Therefore, we seek probe e...

The presence and distribution of glial fibrillary acidic protein, vimentin, neurofilament protein, cytokeratins No. 8 (52 Kd), No. 18 (45 Kd) and No. 19 (40 Kd) and S-100 protein in pituicytes, folliculo-stellate cells, the epithelium of the Rathke's cysts and squamous cell nests of the pars tuberalis were investigated immunohistochemically by the peroxidase-antiperoxidase (PAP) method in eleve...

adhesion level for the proper running of rail wheelset on track is crucial problem in detecting slippage to avoid accidents. the slippage of rail wheels has been observed applying forward and lateral motions to slip velocity and torsion motion. the longitudinal and lateral forces behavior is watched with respect to traction force to note correlation based on angle of attack. the deriving torque...
