Scholars have argued that sound in films has not been given much theoretical attention. Without understanding the use of sound in films, a comprehensive knowledge of the meaning and ideology of movies is not possible. This paper explores how heroines’ voices are presented in Tamil movies and provides empirical evidence about gender inequality in the aural practices of Tamil movies. The data for this study came from a content analysis of 40 Tamil movies produced in India (1961–2012), 8 websites related to voice dubbing in Tamil movies, and 4 YouTube videos. The term “dubbed voice” refers to the practice of using a voice-actor or dubbing artist to deliver the dialogue while someone else acts in the movie. In Tamil movies, this trend has been common since the 1980s among female actors in lead roles but not among lead male actors. Even though the inability to speak Tamil is one of the reasons for this practice, it does not explain why female stars mostly use a dubbed voice. The male actors–including non-native speakers–often use their own voice. The use of a few select dubbing artists to lend their voices to heroines limits the type of female voices heard (from lead roles) in Tamil movies and narrowly defines the types of women’s voices that are associated with someone who is attractive or good. Therefore, Tamil movies are limiting not only the looks that are showcased on the screen but also the female voices heard in these movies.
Experimental Study on Conducted EMI Mitigation in SMPS using a Novel Spread Spectrum Technique
Premalatha, L.,Raghavendiran, T.A.,Ravichandran, C. The Korean Institute of Power Electronics 2013 JOURNAL OF POWER ELECTRONICS Vol.13 No.4
Switched mode power supplies (SMPS) are power electronic circuits extensively used in a wide range of applications. High frequency switching operation of SMPS causes electromagnetic emissions and has the potential to interfere with system operation, which in turn has an impact on system performance. This makes electromagnetic compatibility (EMC) an important concern. In this paper, a new and simple spread spectrum technique is proposed by modulating chaotic pulse position modulation (CPPM) and pulse width modulation (PWM). The resulting CPWM is implemented to reduce the conducted EMI in SMPS. The proposed method is found to be effective in reducing conduction EMI. The effectiveness and simplicity of the proposed method on spreading those dominating frequencies is compared to the EMI mitigation technique using an external chaotic generator. Finally, the levels of conductive EMI with standard PWM, CPWM with an external chaos generator and the proposed method are experimentally verified to comply with the CISPR 22A regulations. The results confirm the effectiveness of the proposed method.

The meaning of femininity varies in different societies. This study explores the meaning and understanding of femininity in everyday life. The data for this study were collected using the in-depth interview technique with twelve Malay Muslim women in Malaysia. They were selected using a purposive sampling technique. After the interviews were transcribed, the data was analyzed to identify common themes in the meaning of femininity among these women. Two main themes were identified: essentialist view of femininity and traditional gender roles and spaces. These themes showed that most participants have an essentialist view of femininity. They also expressed empowerment as an important part of femininity in contemporary society. Their understanding and experiences show how emphasized femininity can be articulated as a form of empowered or liberated femininity.

To know the impact of female pupal weight corresponding to the male cocoon shell weight upon fecundity, hatchability and percentage of non-viable eggs, the experimental multivoltine breeds namely BL67 and 96A were categorised into low, medium and high batches according to the weight of female pupae and male cocoon shells and moths emerged from low, medium and high female pupae were allowed to mate withmoths emerged from low, medium and high male cocoon shells. Both the experimental breeds of BL67 and 96A revealed a fairl trend in fecundity for high batch > medium batch > low batch. When data were statistically analysed, a significant (p < 0.05) and a highly significant (p < 0.01) increase in fecundity was observed in the medium and high batches of BL67 during November - December, 2002 whereas highly significant (p < 0.01) increase was observed in the high batches of 96A during November - December, 2002. Data revealed a highly significant (p < 0.01) increase in fecundity in medium and high batches of both the breeds during January - February, 2003. More interestingly, a significant (p < 0.05) reduction was noted in percentage of non-viable eggs in high batches of 96A during January - February, 2003. But no significant variation in hatchability was noticed due to the effect of differential female pupal weight and male cocoon shell weight.
Real Coded Biogeography-Based Optimization for Environmental Constrained Dynamic Optimal Power Flow
Kumar, A. Ramesh,Premalatha, L. The Korean Institute of Electrical Engineers 2015 Journal of Electrical Engineering & Technology Vol.10 No.1
The optimization is an important role in wide geographical distribution of electrical power market, finding the optimum solution for the operation and design of power systems has become a necessity with the increasing cost of raw materials, depleting energy resources and the ever growing demand for electrical energy. In this paper, the real coded biogeography based optimization is proposed to minimize the operating cost with optimal setting of equality and inequality constraints of thermal power system. The proposed technique aims to improve the real coded searing ability, unravel the prematurity of solution and enhance the population assortment of the biogeography based optimization algorithm by using adaptive Gaussian mutation. This algorithm is demonstrated on the standard IEEE-30 bus system and the comparative results are made with existing population based methods.

Breeding programme was initiated during November, 1995 with the main objective to breed productive multivoltine breeds/ hybrids with suitable genetic constitution to suit the fluctuating tropical climate prevailed in India. Two multivoltine breeds viz., BL-24 and BL-27 selected were as breeding resource materials from the silkworm germplasm maintained at Central Sericul-tural Research and Training Institute, Mysore. By adopting hybridization, backcrossing inbreeding and selection, a new multivoltine breed namely BL-67. This breed spins light greenish yellow cocoons and cocoon shape is oval with medium to coarse grains. The evolved breed was crossed with five tropical bivoltine breeds viz., NB4D2, CSR2, CSR5, CSR18 and CSR101 to study the combining ability, and identified a superior hybrid, BL67 ${\times}$ CSR101, named as CAUVERY, The hybrid is characterized by high pupation rate (>95%), high shell weight (> 35 cg), high cocoon shell ratio (> 20%), longer filament length (> 900 m) and high neatness (93) with a renditta of 6.5 producing 2A-3A grade silk. The hybrid is selected for Race Autho-rization test of Central Silk Board.
