Topological Indices and Bounds for the Energy of Fibonacci Graph
Anitha N.,Savitha H. C.,임동규 장전수학회 2021 Proceedings of the Jangjeon mathematical society Vol.24 No.1
Fibonacci sequence of numbers plays a significant role in communication networks, coding theory, encryption and many such areas. A Fibonacci graph Fd,2n is a d regular graph where d is such that Fd is the largest Fibonacci number less than or equal to n. In this paper we present few lower and upper bounds for the energy of the Fibonacci graph in terms of n, d and the determinant of the adjacency matrix, detA. We have also investigated some topological indices for the Fibonacci graph and the obtained results are tabulated.

Anitha H.,Karunakar A. K.,Dinesh K. V. N. 대한의용생체공학회 2014 Biomedical Engineering Letters (BMEL) Vol.4 No.2
Purpose The scoliosis diagnosing system needs radio-graphicinformation in terms of spinal curvature estimated usingCobb’s definition. The evaluation process and treatmentanalysis depends on the reliability and reproducibility of thespine curvature in the frontal view. Methods Manual identification of end vertebrae and otheranatomical features required for the estimation of spinalcurvature causes variability and unreliability at higher rate. This paper proposes an automated system to extract therequired anatomical features using customized filter. Thecustomized filter used in this paper is a combination ofanisotropic, sigmoid and differential filter. Combination ofthese filters automatically extracts the anatomical features interms of required vertebral endplates. Automatic identificationof these endplates eliminates the human intervention involvedin the quantification of Cobb angle. Results and Conclusions Analysis of the results revealssignificant difference between the observer variabilitybetween manual, computer assisted and computerized imageunderstanding system in terms of inter and intra crosscorrelation coefficient ratio (ICCR).

Radiation-induced fistulas (RIF) are uncommon therapeutic complications of radiotherapy in patients treated for carcinoma of the uterine cervix. Synchronous occurrence of enterocervical and enterovesical fistulas secondary to radiation is extremely rare and previously unreported in the literature. We report a case of synchronous enterovesical and enterocervical fistulas in a patient with carcinoma of the cervix treated using chemotherapy and radiation along with a brief overview of etiopathogenesis of RIF.

V.N.Koteswara Rao. Devana,B.S.L.Mounika,B.Yamini,G.Anitha,G.BalaSaiTarun 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.5
A compact planar monopole antenna with band-notched characteristics suitable for Ultra Wideband (UWB) applications is presented. The proposed UWB microstrip-fed antenna consisting of U-shaped slots in both patch and the microstrip-feed line with a defected ground structure. This antenna is designed to cover the Federal Communication Commission (FCC) bandwidth for UWB applications (2.04-14.6 GHz), while showing tri band-notched characteristics in the frequency bands of: (3-4.3 GHz) used for WiMAX, (6.12-6.8 GHz) used for C-band uplink frequency and (8.7-9.2 GHz) used for aeronautical radio navigation. The proposed antenna is suitable for various narrow band wireless applications, satellite applications and radar applications. The proposed UWB antenna is simulated by using High Frequency Structural Simulator (HFSS).
Fibonacci Graph and its Energies
Chandrashekar Adiga,Anitha N.,Savitha H. C. 장전수학회 2021 Advanced Studies in Contemporary Mathematics Vol.31 No.1
The energy of a graph is dened as the sum of absolute values of its eigenvalues. In this paper, we compute the spectrum and energy of the Fibonacci graph. Numerous matrices can be associated with a graph and their spectrums provide useful information about the graph. In recent times, various other graph energies are studied, based on eigenvalues of several graph matrices. In the present paper, we also establish relationship between the usual energy of the Fibonacci graph and other energies like Signless Lapalcian energy, Randic energy, maximum degree energy, common-neighborhood energy, 2-distance energy and Seidal energy.
The Effect of Gender Imbalance on Housing Price in China
Xinping HAN,W,N,W,AZMAN-SAINI,Anitha ROSLAND,Yasmin BANI,Siong Hook LAW 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.7
House ownership is considered as one of the important pre-conditions for marriage in China. Given that gender imbalance is a prominent issue in the country, competition for marriage partners might motivate males to look for a house and probably bigger and more expensive house. This is believed to have caused house price hikes in recent years. This study aims to investigate the impact of gender imbalance on house prices using data from 30 provinces in China for the 2000–2017 period. The results based on the generalized method of moments (GMM) estimations show that house price is strongly influenced by gender imbalance. However, there is no evidence to support differential effects across eastern and mid-western regions. One potential reason is that pre-marriage house ownership has become a common culture for the whole community and therefore it does not vary significantly across regions. There are several important policy implications. Firstly, the issues should be addressed by the policymakers at national level and not regional level. Secondly, the government should intervene to bring back gender ratio to its normal level. Finally, the government should limit the number of houses people can buy and increase the supply of houses in the market.
Smart City IoT System Network Level Routing Analysis and Blockchain Security Based Implementation

This paper demonstrates, network-level performance analysis and implementation of smart city Internet of Things (IoT) system with Infrastructure as a Service (IaaS) level cloud computing architecture. The smart city IoT network topology performance is analyzed at the simulation level using the NS3 simulator by extracting most of the performance-deciding parameters. The performance-enhanced smart city topology is practically implemented in IaaS level architecture. The intended smart city IoT system can monitor the principal parameters like video surveillance with a thermal camera (to identify the virus-like COVID-19 infected people), transport, water quality, solar radiation, sound pollution, air quality (O3, NO2, CO, Particles), parking zones, iconic places, E-suggestions, PRO information over low power wide area network in 61.88 km × 61.88 km range. Primarily we have addressed the IoT network-level routing and quality of service (QoS) challenges and implementation level security challenges. The simulation level network topology analysis is performed to improve the routing and QoS. Blockchain technology-based decentralization is adopted to enrich the IoT system performance in terms of security.
