 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.

 Abstract

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. The literacy rate has been extended gradually from 8.54% to 63.1% (1961-2011).

 Abstract

The Waiter-Bot is an exceptional autonomous robot which has the ability to follow a designated path like a path finder with the help of IR sensor arrays and reach its intended destination. It is an Arduino based robotic design implemented to seek out and detect its required destination and perform its deliberate tasks with precision and accuracy. The Waiter-Bot consists of simple mechanical design which has simple mechanism with which performing the necessary tasks becomes easier. Due to its design parameters, it also requires less power and draws less current which allows us to work with the robot safely. Moreover, it also adds to the safety to its environment and the people around it. Its light weight builds up allows us to assemble the parts without having the difficulty to carry it anywhere. Once assembled, the entire robot still remains light in its weight and can easily be moved around if necessary. Based on its complete set-up and overall parameters, the waiter-bot stands out on its own to become an important aspect to the solution of this paper. The use of robots as waiters in restaurants is on an increasing trend in the service industry. Restaurants owners have begun to look towards robots to aid in serving the customers due to shortage of waiters. Its light weight build up allows us to assemble the parts without having the difficulty to carry it anywhere. Once assembled, the entire robot still remains light in its weight and can easily be moved around if necessary. Based on its complete set-up and overall parameters, the waiter stands out on its own to become an important aspect to the solution of this thesis project

This study was on influence of social media usage on daily study time and participation in outdoor leisure activities among Faculty of Education Students, University of Calabar, Nigeria. A population of 1,950 level two students were involved. Two hundred and eighty-seven (287) students were randomly selected for the study. Expost Facto research design was adopted for the study. Two null hypotheses were formulated to guide the study. A self constructed instrument (questionnaire) titled �Social Media Usage, Daily Study Time and Participation in Outdoor Leisure Activities Questionnaire� was used to gather data from the respondents. The data collected was coded and subjected to analysis. The first hypothesis which tested social media usage and daily study time was analysed using Chi-square while the second hypothesis which tested the relationship between social media usage and participation in outdoor leisure activities was analysed using Pearson Product Moment Correlation Coefficient. The results showed that social media had significant influence on the two dependent variables. Social media usage negatively affected study time but positively influences outdoor leisure activities. This result was discussed and the researchers recommended that:

As developers while creating apps compatible on cross platforms is a tedious task and poses huge challenges before the developers, to be acquainted with cognizance specific to two or more native platforms. Besides, certain hybrid application frameworks existing in market were not able to cater similar experience to same user on all native platforms. Comprehending a solution to the underlying problem, the research work presented in this paper utilizes the advantages of React-Redux framework to create a hybrid application capable of provisioning solutions. The generated framework can be used for windows and iOS machines and the produced results are satisfactory for the users in both the platforms. The proposed methodology has been implemented using JavaScript ES6.

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.

 Abstract

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.

 Abstract

- 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.
