 Abstract

The modelling of wireless communication channels has been a continuous tantalizing issue while being one of the most fundamental components based on which transmitters and receivers are designed and optimized. The ultimate performance limitation of any communication system are determined by the channel it operates in, Realistic channel models are thus of utmost importance for system design and testing. In this paper we analyse the overall performance of an communication system in different channels based on various parameters such as bit error rate, signal to noise ratio and eye diagram.

According to the report of the Kothari Commission, �The destiny of India is now being shaped in her classroom.� Education inculcates civic and social responsibility. India is a land of many languages, many religions, and many communities and in order to bring them into main stream, education has been considered as the most important means. It is generally believed that education is basic to all development. The advancement of any civilization is very much influenced by the development in education which leads to human resource accomplishment comprising better health and nutrition, improved socio-economic prospective and greater congenial and more useful natural environment for all. Education in India has been considered as self-education which means -making a man, building his life and living. Education constructs the character of pupil; strength of mind .This also helps to stand on his own feet, gives strength and courage during adverse situations. Indian tribals are traditional, conservative and unprivileged people. They belong to socially and economically weaker section. They stay in very remote and inaccessible areas. In India, people belonging to various castes and tribes reside according to their own philosophy, psychology and sociology. The paper is based totally on secondary sources data. The marks of the paper is to analyse the recognition of tribal education, literacy trend of tribal from 1961 to 2011, drop-out rates in Un-divided Koraput district and circumstantially cited the cutting-edge issues and challenges.

Abstract: Twins are relatively rare events, but several studies confirm that they contribute substantially to mortality in both neonatal and post-neonatal periods. The excess infant and child mortality rates among twins calls for a need to identify the main causes behind it. In studies involving multiple individuals from the same family, the independence assumption is not plausible unless all important familial factors were measured and controlled for in the model. Hence, it is important to include random effect or frailty in the model to account for the existence of correlation or unmeasured covariates. This study, therefore, employed survival analysis using gamma frailty models. Information on twin under-five mortality was found from the birth history of women who were included in the 2016 Ethiopia Demographic and Health survey. The results of the study show that sex of child, between twins birth order, preceding birth interval, and succeeding birth interval are significantly associated with under-five twin mortality. In addition, the result of the study confirmed the significance of shared /family random effect.

Till date women have been discarding menstrual blood as an unwanted and unsanitary waste. However, a new research has found that menstrual blood is a rich source of stem cells that have the ability to multiply and differentiate into any kind of cells. Earlier, blood from umbilical cord was regarded as the ultimate reserve for stem cells. Only those who have given birth at anytime of their life were able to preserve the stem cells as they were obtained from umbilical cord. But researchers have now discovered and successfully harvested stem cells from menstrual blood making it possible for all the women including those who have never given birth to preserve stem cells for themselves. Menstrual stem cells could offer a lot of advantages over the other stem cells as the source is easy to find because every woman is a source, quantity available is more, the fear of tissue rejection is minimal and above all the question of ethical issues related to using embryonic stem cells are avoided. Menstrual Blood Banking appears to be an innovative, promising, cost effective, novel and ethically acceptable alternative concept which needs to be popularized in the field of medicine.

- Data security is, protecting data from ill- conceived get to, utilize, intrusion, change, examination, recording or destruction. Cloud computing is a network-based service that provide sharing of resources such as virtual machine, storage, network, software and applications etc. It helps to reduce capital costs since that cloud users only need to rent resources according to their requirements and pay the services they use. It is very flexible since users can access its service in any place through internet. However, a variety of security concerns such as integrity, availability and privacy act as barriers for cloud users to adopt the cloud service. The key issue in effective execution of Cloud Computing is to adequately deal with the security in the cloud applications. To secure the Cloud means secure the treatments (calculations) and storage (databases hosted by the Cloud provider). In this research paper, the proposed work plan is to eliminate the concerns regarding data privacy using two cryptographic algorithms back to back to enhance the security in cloud and provide the digital signature as per different perspective of cloud customers.

Indian Regional Navigation Satellite System (IRNSS) or Navigation with Indian Constellation (NavIC) has been developed and monitored by ISRO, India. IRNSS measurements are being affected by many residuals or biases. Differential Code Bias (DCB), is one of the main error sources to estimate the precise Total Electron Content (TEC) in the ionosphere. Differential delay biases of the dual-frequency band signals in both satellite and receiver are called satellite differential code biases (SDCBs) and receiver differential code biases (RDCBs). In this paper the combined satellite and receiver DCBs are measured. The DCB estimation of IRNSS signals is important for improving IRNSS user positioning accuracy in real-time applications.

The aim of image enhancement is to improve the interpretability or perception of information in images for human viewers, or to provide `better' input for other automated image processing techniques such as biometric based techniques that include face recognition, fingerprint matching, early detection of biological disorder like cancer etc. Image enhancement techniques can be divided into two broad categories: spatial domain techniques, which operate directly on pixels, and frequency domain techniques, which operate on the Fourier transform of an image. Frequency domain image enhancement techniques are based on modifying the Fourier transform of an image. Smoothing domain filters, sharpening domain filters, Homomorphic filters are few of them which are used for image enhancement. In the present work such filters have been designed and implemented. A comparison has been made over aforesaid frequency domain image enhancement techniques using various filters and their performances have been evaluated in terms of PSNR (peak signal to noise ratio), CNR (contrast to noise ratio), mean, variance and invariant moments. For better visual interpretation of a colour image a special technique colour image enhancement has also been successfully implemented. The results of present research work have been applied to one of the forensic science applications i.e. fingerprint matching. It has been observed that matching accuracy is improved if fingerprint image is enhanced in frequency domain before subjecting it to the matching process.
