Several optical network switching paradigms have been under intensive research to support rapidly increasing bandwidth requirements. Of all these paradigms, optical burst switching (OBS) is a promising switching paradigm for the next-generation Internet infrastructure. Despite the significant contributions of OBS to high speed networks such as dynamic connection setup and strong separation between data and control plane, there are several issues that are to be resolved because the present OBS research studies have many differences and thus need further study. In this paper, some of author's own past researches have been summarized to overcome few issues of OBS; related to network architectures, contention, burst assembly, congestion, complex scheduling schemes, quality of service (QoS), burst dropping, routing etc. © 2011 SBMO/SBMag.

Densities and ultrasonic speeds have been measured over the whole composition range for binary liquid mixtures of dipropylene glycol dimethyl ether, CH3(OC3H6)2OCH3, with methyl acetate, ethyl acetate, and n-butyl acetate using an Anton Paar DSA 5000 M density and speed sound analyzer at T = (288.15, 293.15, 298.15, 303.15, and 308.15) K and atmospheric pressure in order to evaluate the behavior of these binaries. From these data excess the molar volume, V m E, and deviation in isentropic compressibility, â̂†κ S, have been calculated. These excess properties have been fitted with the Redlich-Kister type polynomial equation to get their coefficients and standard deviations which provide a base for discussing the forces operating in solutions. © 2013 Springer Science+Business Media New York.

In our paper, we prove common fixed-point theorem on the basis of control functions in FM-spaces. Using the fuzzy edition of the Banach contraction principle, the present theorem generalized the Banach contraction principle using the continuous control function. Condition of continuity for mappings P;Q; S and T is not required. Our result generalizes the accumulation of compact subsets of Y; where the assemblage HM itself is an FM-space. Here, we prove the result for two pairs of single-valued and set-valued owc mappings. Also, we give example to justify our result. © Springer Science+Business Media Singapore 2016. Source

Advancement in wireless sensor networks technology enables a wide range of applications such as health care, industrial automation, ambient conditions monitoring and security and defense systems. WSNs designers are facing many challenges in meeting application requirements e.g. reliability, fault tolerance, lifetime, throughput and responsiveness etc as application requirements and environmental conditions change over time. Failure of WSN may result catastrophic consequences like loss of life in the case of health care application and major disasters in the case of defense systems. This paper presents a probabilistic model for reliability analysis in WSNs by adding redundancy within a sensor node. © Research India Publications. Source

Aim: To assess the protective efficacy of Strobilanthes callosus against the acute and chronic inflammation on rat model. Methods: Inflammation was induced by carrageen and Freund's complete adjuvant in plantar surface of the rats. The ethanol, chloroform and petroleum ether extracts in three divided doses (100, 200 and 400 mg/kg) were administered orally. Diclofenac sodium (10 mg/kg), prednisolone (5 mg/kg) and methotrexate (0.5 mg/kg) were used as standard. The statistical significance between means was analyzed using a one-way analysis of variance followed by Tukey's multiple comparison test. A p <0.005 was considered as statistically significant. Results: Pet. ether (200 and 400 mg/kg) and ethanol extract (100 and 400 mg/kg) showed statistically significant (p < 0.001) effect in analgesic activity. In a carrageen-induced model, only pet. ether extract (100 and 400 mg/kg) confirmed statistically significant effect (p < 0.001) at every interval (four in all) of 1 h. In Freund's adjuvant model, Pet ether and ethanol extract (200 and 400 mg/kg) have shown statistically significant effect (p < 0.001) and in case of chloroform extract only single dose (400 mg/kg) were observed statistically significant results considered to be anti-arthritic effects. The histopathology pictures showed there was positive inhibition of arthritis at a certain level in different groups compared to positive control group. Conclusion: Pet. ether and ethanol extracts of S. callosus were observed to have a promising efficacy against acute and chronic inflammation. © 2012 Springer Basel AG. Source
