Multiple object tracking with partial occlusion handling using salient feature points
Naushad Ali, M.M.,Abdullah-Al-Wadud, M.,Lee, S.L. North-Holland [etc ; Elsevier Science Ltd 2014 Information sciences Vol.278 No.-
Handling occlusion has been a challenging task in object tracking. In this paper, we propose a multiple object tracking method in the presence of partial occlusion using salient feature points. We first extract the prominent feature points from each target object, and then use a particle filter-based approach to track the feature points in image sequences based on various attributes such as location, velocity and other descriptors. We then detect and revise the feature points that have been tracked incorrectly. The main idea is that, even if some feature points are not successfully tracked due to occlusion or poor imaging condition, the other correctly tracked features can collectively perform the corrections on their behalf. Finally, we track the objects using the correctly tracked feature points through a Hough-like approach, and the object bounding boxes are updated using the relative locations of these feature points. Experimental results demonstrate that our method is proficient in providing accurate human tracking as well as appropriate occlusion handling, compared to the existing methods.
Efficient finite element model for dynamic analysis of laminated composite beam
Naushad Alam, M.,Upadhyay, Nirbhay Kr.,Anas, Mohd. Techno-Press 2012 Structural Engineering and Mechanics, An Int'l Jou Vol.42 No.4
An efficient one dimensional finite element model has been presented for the dynamic analysis of composite laminated beams, using the efficient layerwise zigzag theory. To meet the convergence requirements for the weak integral formulation, cubic Hermite interpolation is used for the transverse displacement ($w_0$), and linear interpolation is used for the axial displacement ($u_0$) and shear rotation (${\psi}_0$). Each node of an element has four degrees of freedom. The expressions of variationally consistent inertia, stiffness matrices and the load vector are derived in closed form using exact integration. The formulation is validated by comparing the results with the 2D-FE results for composite symmetric and sandwich beams with various end conditions. The employed finite element model is free of shear locking. The present zigzag finite element results for natural frequencies, mode shapes of cantilever and clamped-clamped beams are obtained with a one-dimensional finite element codes developed in MATLAB. These 1D-FE results for cantilever and clamped beams are compared with the 2D-FE results obtained using ABAQUS to show the accuracy of the developed MATLAB code, for zigzag theory for these boundary conditions. This comparison establishes the accuracy of zigzag finite element analysis for dynamic response under given boundary conditions.

The main goal of this study was to evaluate the performance of two new adsorbents, ash and Fe nanoparticles loaded ash (nFe-A) for the removal of Pb(II) from aqueous solution. Batch experiments were performed as a function of various experimental parameters. The adsorption studies included both equilibrium adsorption isotherms and kinetics. Equilibrium data fitted very well with the Langmuir isotherm model. Kinetics studies showed better applicability for pseudo-second-order model for both adsorbents. The regeneration studies showed promising regeneration potential of these adsorbents. The breakthrough capacities of ash and nFe-A for Pb(II) removal was found 25 and 30 mg g 1, respectively.

EDTA-Zr(IV) iodate was prepared via the incorporation of aqueous solution of EDTA into the inorganic precipitate of Zr(IV) iodate. Distribution coefficient values for different metals showed that EDTA-Zr(IV) iodate had the highest adsorption capacity for Pb(II). The practical applicability of EDTA-Zr(IV) iodate was explored by separating Pb(II) metal from a synthetic mixture of metal ions. Dependence of adsorption on contact time, pH of the solution, exchanger dose and temperature was studied to achieve the optimum conditions. Kinetic studies showed better applicability for pseudo-second-order model. Thermodynamic parameters viz. – entropy change, enthalpy change and Gibb’s free energy change were also calculated.

Fig sawdust was used as a precursor for the production of activated carbon by chemical activation withH3PO4. The developed Fig sawdust activated carbon (FSAC) was used as a biosorbent for the removal ofPb(II) from aqueous solution. Highest adsorption of Pb(II) (95.8%) was found at pH 4. Equilibrium datafitted very well with the Langmuir isotherm model. Maximum adsorption capacity was determined80.645 mg g1 at pH 4. Kinetic studies demonstrated that the adsorption followed a pseudo second orderkinetics model. The negative value of DG8 confirmed the feasibility and spontaneity of FSAC for Pb(II)adsorption.

The present work deals with the removal of highly toxic Cd2+from wastewater using ecofriendlycurcumin (7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione) formaldehyde resin (CFR). The CFR resin was characterized using several analytical techniques. The adsorption kinetics andisotherms were well fitted by pseudo-second-order and Freundlich models, respectively. The adsorptionof Cd2+ onto CFR was increased with the ionic strength (NaCl). The regeneration studies demonstrated adecrease in the adsorption of Cd2+ from 94% to 80% after five consecutive cycles. All results illustratedthat CFR was a promising adsorbent for the environmental pollution cleanup.

In the present paper, Amberlyst-15 resin was used for the removal of malathion. Various experimentalparameters such as effect of pH, contact time, resin dose, initial malathion concentration andtemperature were studied to find the optimum conditions for malathion removal. The removal rate ofmalathion by Amberlyst-15 was rapid and equilibrium was established within 30 min. Kinetic studiesshowed better applicability for pseudo-second-order model and equilibrium data was best fitted toFreundlich isotherm model. The thermodynamic parameters showed that the adsorption of malathionwas feasible, endothermic and spontaneous. The concentration of malathion was determined usingultra-performance liquid chromatography–tandem mass spectrometry.

A mesoporous magnetic zirconium phosphate was prepared for the removal of Hg2+ from aqueous medium. The saturation magnetization of pure Fe3O4 and Fe3O4@ZrP was observed 82.9 and 62.4 emu/g, respectively. The effect of different adsorption parameters was studied. The kinetic data were fitted to the pseudo 1st and pseudo 2nd order models whereas the adsorption process was best fitted into the pseudo 2nd order model. The adsorption isotherm could be well described with Langmuir model, with the maximum adsorption capacity of 181.8 mg g1 at 25 C. Thus, the present studies suggested that Fe3O4@ZrP have remarkable potential for Hg2+ removal from contaminated water.
