    All living things have the right to live on the Earth. There should be no difference even among high-ranking people. Transgenders are human beings like male and female. They should also be treated as equals and be respected as a living being. But they are ridiculed and teased in society. People who are inferior in levels of caste, occupation, politics, sexual status, economic status can be termed as marginal. But the Dalits, black women, transgenders etc. Are always considered as the margins. Among such marginalized ranks, the social esteem of transgenders are very low. Caste-based atrocities treat women as inferior because they are women. Overall they are human beings and should be treated equally in society. This article investigates about the notes on transgenders in Tamil literary works

    3D Face Recognition using Significant Point based SULD Descriptor

    Full text link
    In this work, we present a new 3D face recognition method based on Speeded-Up Local Descriptor (SULD) of significant points extracted from the range images of faces. The proposed model consists of a method for extracting distinctive invariant features from range images of faces that can be used to perform reliable matching between different poses of range images of faces. For a given 3D face scan, range images are computed and the potential interest points are identified by searching at all scales. Based on the stability of the interest point, significant points are extracted. For each significant point we compute the SULD descriptor which consists of vector made of values from the convolved Haar wavelet responses located on concentric circles centred on the significant point, and where the amount of Gaussian smoothing is proportional to the radii of the circles. Experimental results show that the newly proposed method provides higher recognition rate compared to other existing contemporary models developed for 3D face recognition

    In this paper, the problem of direction of arrival estimation is addressed by employing Bayesian learning technique in sparse domain. This paper deals with the inference of sparse Bayesian learning (SBL) for both single measurement vector (SMV) and multiple measurement vector (MMV) and its applicability to estimate the arriving signal’s direction at the receiving antenna array; particularly considered to be a uniform linear array. We also derive the hyperparameter updating equations by maximizing the posterior of hyperparameters and exhibit the results for nonzero hyperprior scalars. The results presented in this paper, shows that the resolution and speed of the proposed algorithm is comparatively improved with almost zero failure rate and minimum mean square error of signal’s direction estimate

    Human growth hormone alters carbohydrate storage in blood and liver in both genders of an Indian bird, Acridotheres tristis (Linn.)

    Background: Growth hormone (GH) is a peptide hormone that plays vital roles in cell growth and metabolism. Aim: The study investigates the effect of GH on carbohydrate metabolism using Indian bird, Acridotheres tristis. Methods: Three different doses (0.4, 0.6, and 0.8mg/100g body weight) of human growth hormone (HGH) given once to both genders of a bird Acridotheres tristis to observe the effect on blood glucose and hepatic glycogen content in the body. Glucose and glycogen were quantitatively assayed. Results: Their effect was recorded for different time intervals (1, 4, 12, 24, 72, 96, and 144 h). Hypoglycaemic condition was recorded within an hour of hormone treatment in male and female birds. The lowest dose (0.4mg/100g body weight) was more effective than other two doses. Simultaneous depletion of hepatic glycogen was also recorded, although initially increase in glycogen level was also noticed in both genders. It was noticed that the highest dose (0.8mg/100g body weight) was most responsive. Conclusion: The effect of human growth hormone was not dose and time dependent in both male and female birds. HGH is thus hypoglycaemic and hepatic glycogenolytic in nature in A. tristis.Key words: Human growth hormone, blood glucose, hepatic glycogen, hypoglycaemia, glycogenolysis, bir

    Mass Transfer Effects on Unsteady Free Convective Flow Past an Infinite, Vertical Porous Plate with Variable Suction

    A two-dimensional unsteady flow of a viscous incompressible dissipative fluid past an infinite, vertical porous plate with variable suction, is studied. Approximate solutions to the coupled non linear equations governing the flow are derived and expressions for the fluctuating parts of the velocity, the transient velocity, temperature and concentration, the amplitude and the phase of the skin-friction, and the rate of heat transfer, are derived. The effects of w(Omega)(frequency), Gr (Grashof number), Gc (modified Grashof number), Sc (Schmidt number), P (Prandtl number) and A (variable suction parameter), on the above physical quantities are calculated numerically and presented in figures and table. Problems of this nature find place in ablative cooling, transpiration and film cooling of rocket and jet engines
