Murali Krishna Rao, M.,Venkateswarlu, B. The Korean Society for Computational and Applied M 2016 Journal of applied mathematics & informatics Vol.34 No.5

The notion of Γ-semiring was introduced by M. Murali Krishna Rao [8] as a generalization of Γ-ring as well as of semiring. In this paper fuzzy k-ideals, k-fuzzy ideals and fuzzy-2-prime ideals in Γ-semirings have been introduced and study the properties related to them. Let μ be a fuzzy k-ideal of Γ-semiring M with |Im(μ)| = 2 and μ(0) = 1. Then we establish that M_μ is a 2-prime ideal of Γ-semiring M if and only if μ is a fuzzy prime ideal of Γ-semiring M.

Y. Murali Krishna,K. Murali Krishna,Ch. Amaranatha Sarma 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.5

Signal processing takes an important role in genomic with enormous data available in public domain. Generally digital filters are applied to predict the protein and genes, but it needs to be redesigned when the characteristic frequency and periodic behavior is changed. In this paper proposed the novel adaptive algorithm which can identify the genes and proteins effectively from unified framework. First using the electron ion potential method the symbolic DNA sequences are converted in to digital signal. Secondly the filtering scheme for genomic signal processing with periodic behavior in biological sequence is introduced, which can predict and analyze the biological region that are interested in. finally the proposed adaptive filtering method is applied to recognize the exons of protein coding regions according to periodic-3 property. The exons prediction curves are obtained with Discrete Fourier Transform (DFT), Least mean square (LMS), and proposed Fast Recursive least Mean Square (F-RLS) algorithms. It is shown that proposed method shows efficiency in convergence of identification and precise prediction of exons regions compared to existed methods.

Impact of Inertia Emulation Based Modified HVDC Tie-Line for AGC Using Novel Cascaded Fractional Order Controller in Deregulated Hybrid Power System

Murali Sariki,Shankar Ravi 대한전기학회 2021 Journal of Electrical Engineering & Technology Vol.16 No.3

This article deals with the Automatic Generation Control (AGC) mechanism for an interconnected, deregulated hybrid power system. The physical generation constraints such as boiler dynamics, governor dead band (GDB) and generation rate constraints (GRC) are included for a more realistic approach. The integration of distributed generation (DG) systems is also considered to match with present scenario. The intermittency nature of the DGs ruins the system’s inertia and dynamic behaviour. A novel cascaded fractional order controller confi guration 2-DOF (FOPI λ DN)-PDN is proposed for the AGC mechanism and a new quasi opposition based volleyball premier league (QVPL) algorithm is employed to optimize the controller gains. On the other hand, the inertia emulation strategy (IES) based modifi ed HVDC tie-line is used parallel to the AC tie-line to retrace the power system’s inertia. The impact of the proposed controller and IES based modifi ed HVDC tie-line has been analysed by subjecting to several case studies. The eff ectiveness of the QVPL based proposed controller has also been tested by comparing it with the previously published works on the same platform.

Alcohol intoxication and driving is responsible for a high proportion of traffic accidents. Drunken driving is the act of driving a motor vehicle with blood alcohol concentration (BAC) level in excess of a legal limit. In Korea, the legal limit for BAC is 0.05 %. Even with a small amount of alcohol intake, drivers are twice likely to be involved in traffic accidents than normal drivers. Alcohol use impairs drivers’ cognition, vigilance, attention, judgment, reaction, vision, and braking behavior. This pilot study was to investigate effects of alcohol intoxication on physiological behavior and driving performance in different BAC levels in a simulated driving environment. The physiological measures were EEG (alpha and theta frequency in the frontal and occipital region), and ECG (heart rate and R-R interval). The driving performance measured were accident rate and the number of time violating the specified speed limit (50, 70, 90, 110 km/h). Participants consisted of four healthy young male drivers (Age: 31 ± 4.3 years). The BAC levels considered were 0.00 % (control), 0.03, 0.05 and 0.1 %. The scenario considered was 5 min driving in a highway with different speed limits and unexpected event. Results showed that decreased alpha and increased theta frequency was observed with increased BAC level. Heart rate was increased with increased BAC level. The accident rate and the number of time violating the speed limit were significantly (p<0.05) higher with higher BAC level. Alcohol intoxication affected drivers’ decision-making ability, vision and integrating visual information ability.

LATTICE OF KEYCHAINS

MURALI, V. 한국전산응용수학회 2006 Journal of applied mathematics & informatics Vol.20 No.1

In this paper we consider the set of all n + 1-tuples of real numbers, not necessarily all distinct, in the decreasing order from the unit interval under the usual ordering of real numbers, always including 1. Such n + 1-tuples inherently arise as the membership values of fuzzy subsets and are called keychains. An natural equivalence relation is introduced on this set and the equivalence classes of keychains are studied here. The number of such keychains is finite and the set of all keychains is a lattice under the coordinate-wise ordering. Thus keychains are subchains of a finite chain of real numbers in the unit interval. We study some of their properties and give some applications to counting fuzzy subsets of finite sets.

Comparative Experimental and Analytical Modeling of Impact Energy Dissipation of Ultra-High Performance Fibre Reinforced Concrete

Murali G,Venkatesh J.,Lokesh N.,Nava Teja Reddy,Karthikeyan K. 대한토목학회 2018 KSCE Journal of Civil Engineering Vol.22 No.8

This study examines the impact energy dissipation capacity of Ultra High Performance Fibre Reinforced Concrete (UHPFRC). Forthis purpose, nine different mixes were fabricated with hooked end and crimped steel fibres at a dosage of 0.5, 1.0, 1.5 and 2.0percentage and tested under pendulum impact test. The impact energy dissipation capacity is assessed based on test (Charpy U-notch)procedure suggested by ASTM E23. Also, an analytical model was adopted to predict the impact energy dissipation value ofUHPFRC and its performance is verified against experimental results. Based on the test results, the impact energy dissipationcapacity of the mixtures containing crimped and hooked end steel fibres were significantly higher than that of Plain Concrete (PC). The hooked end steel fibres had an increased impact energy dissipation capacity compared to crimped steel fibres, which implies thathooked end steel fibre is more appropriate for enhancing the impact energy dissipation of UHPFRC. Also, the modelling datacompared well with experimental data for the fibre volume fraction beyond 0.5%.

( Murali Subramaniyam ),( Sangho Park ),( Seung Nam Min ),( Se Jin Park ) 한국감성과학회 2015 추계학술대회 Vol.2015 No.-

The Korean population is constantly evolving. According to the National Statistical Office (NSO), people over 65 years of age will account for 38.2 percent of Korea’s population in 2050, making it the most aged society among the 30 member economies of the Organization for Economic Cooperation and Development (OECD). Lifting tasks have been shown to be a risk factors of low back injuries in young adults. As aging is related to loss of muscle strength, working elderly subjects exposed to manual handling and lifting tasks may be more prone to develop back injuries. The manual lifting strategies influenced by back and leg extensors strength. This study sought to investigate whether the isometric muscle strength and lifting capacity affected by aging. The sample consisted of a total of 45 elderly (20 male and 25 female) and 40 young (20 male and 20 female) adults. Lifting capacity was measured with the back-leg dynamometer. Isometric muscle strength was recorded simultaneously with the capture of the electrical activity of left (LT) and right (RT) side lumbar erector spinae (ES) muscle. A surface electromyography (sEMG) system was used to measure the electrical activity of the muscles. Results showed that there was a significant reduction in elderly lifting capacity than younger adults. The elderly adults had significantly lower muscle strength in the isometric muscle strength compared to younger adults.
