Kumar M. Infant Shyam,Kirupavathy S. Shahil,Shalini S. 한국탄소학회 2021 Carbon Letters Vol.31 No.4

Most recently, graphene-related composite-modifed electrode surfaces are been widely employed to improve surface interactions and electron transfer kinetics. Hydrothermally prepared strontium pyro niobate (SPN) and reduced graphene oxide/ strontium pyro niobate (RGOSPN) nanostructures reveal excellent morphology. X-ray difraction analysis of SPN and RGOSPN agree with standard data. Thermogravimetry–diferential scanning calorimetry analyses show that RGOSPN has higher thermal stability than SPN. In addition, from the polarization–electric feld (P–E) loop measurements, the estimated value of remnant polarization (Pr ) and coercive electric feld (Ec) of SPN are 0.039 µC cm−2 and −2.90 kV cm−1 and that of RGOSPN nanocomposite are 0.0139 µC cm−2 and −2.04 kV cm−1. Cyclic voltammetry measurements show that RGOSPN nanocomposite manifests the possibility of electrochemical reversibility beyond long cycles without change in performance. The redox cycle reveal that RGOSPN can be used as part of a composite electrode for hybrid capacitors dynamic conditions. Moreover, the specifc capacitance of SPN and RGOSPN was calculated using galvanostatic charge–discharge (GCD) technique. The observed energy density of 9.1 W h kg−1 in RGOSPN is higher when compared with previous reported values.

An SEIR endemic model for Monkeypox spread in united states

S. Shalini Priya,K. Ganesan 한국전산응용수학회 2023 Journal of applied mathematics & informatics Vol.41 No.5

In this paper, we construct a monkeypox model which is similar to smallpox infection. It is caused by a monkeypox virus which is related to Poxviridae family. It will occur mostly in West African communities and in remote Central. We develop a system of differential equations for an SEIR (Suspected, Exposed, Infected and Recovered) model and analyze the outbreak of monkeypox disease and its effect on United States(US) population. We establish theorems on asymptotical stability conditions for endemic equilibrium and disease-free equilibrium. The basic reproduction number $R_0$ has been determined using next generation matrix. We expect that this study will be effective at controlling monkeypox spread in United States. Our goal is to see whether monkeypox can be controlled and destroyed by smallpox vaccination. We find that monkeypox is controllable and can be fully destroyed in disease free state by vaccination. However, in the endemic state, monkeypox cannot be destroyed by vaccination alone.

On the reciprocity theorem of Ramanujan and its Generalizations

D. D. Somashekara,K. N. Murthy,S. L. Shalini 장전수학회 2012 Proceedings of the Jangjeon mathematical society Vol.15 No.3

In his lost notebook, Ramanujan has stated a beautiful two variable reciprocity theorem. In the recent past, three and four variable generalizations of the reciprocity theorem of Ramanujan were established. In this paper, we give an unified approach to the proofs of all the three reciprocity theorems. Some new q-gamma, q-beta and eta-function identities were also be deduced from the four variable reciprocity theorem.

Synthesis and microwave characterization of Bi- substituted barium lanthanum titanate

S. Bindra Narang,Shalini Bahel,Dalveer Kaur 한양대학교 세라믹연구소 2007 Journal of Ceramic Processing Research Vol.8 No.5

Bi-substituted barium lanthanum titanates with the general formula Ba4(La(1-z)Biz)9.33Ti18O54 where z = 0.0 to 0.2 in steps of 0.05 were synthesized by a conventional mixed oxide route. The composition and morphology were determined using scanning electron microscopy (SEM) and X-ray powder diffraction analysis (XRD). Two dielectric performance parameters, namely dielectric constant and loss tangent were measured with varying microwave frequency in the range 0.3 to 3 GHz at room temperature. It was observed that the dielectric constant and loss tangent both increased initially for z ≤ 0.10 and then decreased. The best properties were obtained for z = 0.20 with a dielectric constant of 91.4 and loss tangent of 0.004. This could be a promising microwave material with a high dielectric constant and low loss.

Low loss dielectric ceramics for microwave applications: a review

S. Bindra Narang,Shalini Bahel 한양대학교 세라믹연구소 2010 Journal of Ceramic Processing Research Vol.11 No.3

Microwave dielectric ceramics have been used for a wide range of applications from wireless communication (including mobile communication, ultra high speed local area networks, intelligent transport system, satellite communication) to consumer electronic products. The need for portable, light weight and multifunctional electronic components has forced scientists to search for new advanced microwave materials. During the past 25 years, a large number of dielectric materials have been developed and the properties of existing materials have been improved. However, the data on these very useful materials are scattered. The main purpose of this review is to bring together the data of low loss microwave dielectric ceramics and classify them according to their applications. This should be of immense help to researchers and technologists all over the world.

In this paper a comparison between Third Generation technology and WLAN ( both are parallel technologies first one embodied by IMT-2000 standards and the second one by ITU Standards) has been made and also a comparison between Wi-Fi and Bluetooth has been made.

Trust Based Authentication and Key Establishment for Secure Routing in WMN

( G. Akilarasu ),( S. Mercy Shalinie ) 한국인터넷정보학회 2014 KSII Transactions on Internet and Information Syst Vol.8 No.12

In Wireless Mesh Networks (WMN), an authentication technique can be compromised due to the distributed network architecture, the broadcast nature of the wireless medium and dynamic network topology. Several vulnerabilities exist in different protocols for WMNs. Hence, in this paper, we propose trust based authentication and key establishment for secure routing in WMN. Initially, a trust model is designed based on Ant Colony Optimization (ACO) to exchange the trust information among the nodes. The routing table is utilized to select the destination nodes, for which the link information is updated and the route verification is performed. Based on the trust model, mutual authentication is applied. When a node moves from one operator to another for accessing the router, inter-authentication will be performed. When a node moves within the operator for accessing the router, then intra-authentication will be performed. During authentication, keys are established using identity based cryptography technique. By simulation results, we show that the proposed technique enhances the packet delivery ratio and resilience with reduced drop and overhead.
