Admission Control plays a remarkable role in dealing with lots of wireless heterogeneous networks which may admit new sessions for a network with most conquer aspect to supply the requested QoS. To keep off the abjection of QoS under the low priority sessions here, we nominate a QoS based Robust Call Admission Control (RCAC) Algorithm. The service classes are assorted into four major categories on the basis of class of service and type of service, which could be reacted on the real time and non real time traffics along with handover and incoming new request. The algorithm concentrates on providing priority based on transmission and space. This algorithm trying to downplays the blocked sessions that have been chosen with deficient resources around the network. With the help of simulated results and graph, we display that our suggested technique affords improve throughput along with cut down in delay. © 2005 - 2014 JATIT & LLS. All rights reserved.

In the present study, optimization of phenol adsorption onto garlic peel (GP) was conducted with process parameters such as initial pH, adsorbent dosage, agitation speed, and contact time. The percentage removal of phenol was optimized based on these process parameters. Response surface methodology was used for optimization as it has many advantages over classical optimization methods. A Box–Behnken experimental design was employed. The optimum conditions for maximum removal of phenol from an aqueous solution of 50 mg L−1 were found as follows: pH: 2, adsorbent dosage: 2.1 g L−1, contact time: 7 h, and agitation speed: 135 rpm. At these optimized conditions, batch adsorption experiments were conducted to study the effects of initial concentration and temperature on phenol removal. Thermodynamic parameters such as (Formula presented.) and (Formula presented.) were also evaluated. From the results, the sorption process was found to be spontaneous and exothermic. The equilibrium experimental data were analyzed with several isotherm models. The adsorption kinetics for phenol removal by GP follows the pseudo-second-order kinetic model. The results from the study demonstrated that more than 80% phenol removal is possible at the above-mentioned optimum conditions. © 2014 Balaban Desalination Publications. All rights reserved.

Intrusion is the primary step to conduct various kinds of network attacks. Most of the intrusion detection and intrusion prevention systems (IDPS) that make use of signature can detect only known attacks, but cannot save resources from new form of attacks like internet worms. Thus, it is necessary to collect information about unknown intrusion dynamically. Honeypots are useful security mechanism that deliberately lure intruders to probe, attack or compromise the systems. This paper presents an agent based honeymesh for protecting the network resources like servers from intrusion related attacks. In our strategy, agent programs make use of decoyports to lure intruders and redirects to honeymesh to understand attackers’ activities. Also, the agents remove malicious processes and executable files on compromised server as soon as honeypots alerts those intrusions. This novel defense mechanism detects and removes new kinds of internet worms without using signatures. © 2016 Springer Science+Business Media New York

The coagulation process using NaCl and KCl salt solution extracted protein from Moringa oleifera seeds is reported for tannery wastewater treatment in the present study. The important process parameters coagulant dosage and pH were optimized using Hessian matrix approach. Central composite design employing coagulant dose and pH as input variables was considered for developing response surface models for colour (%) and turbidity (%) removal. The dosage 45 mL and pH 7 was found to be optimum conditions for maximum 84 % colour removal by NaCl extracted coagulant, whereas for KCl extracted coagulant optimal point was 46.1 mL dosage and pH 6.9. For turbidity (%) removal using NaCl extracted coagulant the optimum condition was 40.2 mL dosage and pH 7.5. The removal efficiency of NaCl extracted coagulant was more than KCl extracted coagulant suggesting that NaCl salt solution is more effective in extracting the active agent from Moringa oleifera seeds.

Single crystals of glycinium hydrogen squarate (GHS) have been successfully synthesized and purity of the material has been increased by repeated recrystallization process. Single crystals were grown by slow evaporation solution growth technique using water and ethanol as solvents at room temperature. Then the grown crystal was characterized by different techniques for finding its suitability for device fabrications. The grown crystal was characterized by single crystal XRD, powder XRD, FT-IR, UV-Vis-NIR, 1H NMR, 13C NMR, SHG and DTA/TGA analyses respectively. From the single crystal XRD diffraction, the crystal system was identified as monoclinic. The presence of functional groups were identified by FT-IR analysis. The UV transparency cut-off wavelength of the grown crystal occurs at 342 nm. 1H NMR and 13C NMR spectroscopic studies were employed to elucidate the structure of the grown crystal. The second harmonic generation efficiency test by Kurtz-Perry technique showed positive result. The decomposition temperature of the grown crystal was studied by DTA/TGA analysis. The results observed from the characterization analyses show its suitability for NLO applications. © 2012 Elsevier B.V. All rights reserved.
