Determination of dielectric strength of electrical porcelain insulators from local clays using a snail shell as an additive

In this thesis, the development of electrical porcelain insulators based on local clays has been investigated. The test samples were made by varying the quantities of silica and feldspar required to form a mouldable plastic body with each clay sample. The clay samples were bisque fired to 900°C and glazed before it was fired to 1250°C after air-drying. Electrical properties such as dielectric strength (breakdown voltage) were determined for each test sample that survived the high temperature.

Coverage of dalit issues in kannada newspaper- A content analysis

The purpose of this study is to analyze the coverage of dalit issues in Kannada newspaper. This research proposes to know the major categories published in different newspapers, to examine the space given to dalit issues and to find out how dalits are portrayed in newspaper. The primary data was collected through the Content analyses method. The study included two newspapers Vijayavani and Vijayakarnataka for the period of three month i.e. January to March 2016. The newspapers were selected randomly on the basis of their highest circulation.

Effect of torque in friction stir welding of aa6061-az61

The recent trend of research on joining of dissimilar alloys leads the interest towards the study and analysis of Friction Stir welding. Joining of different steel groups and Aluminium has been on the research interest on the previous decade. Recent innovative research and development area is on with Magnesium alloy groups. The Aluminium alloys and Magnesium alloys are investigated for the weld strength with respect to the change of welding parameters including tool geometry, the tool transverse speed, and the tool angular velocity.

Using new communication technology to involve stakeholders in a strategic planning process: an social learning approach design with the delphi and gdss

The consideration of sustainable development and the governance reinvent a negotiation and consultation culture around the public stake concerns and fertilize the group animation practices. As regards development plan, policy and program evaluation, the strategic stakes negotiation process remains difficult and its success dubious.

Constraints on research productivity in Kenyan universities: case study of university of Nairobi, Kenya

Besides teaching, research has become a core function of universities around the world. Yet, like in many African countries, Kenyan universities still lag behind in terms of research productivity, due to factors many researchers refer to as constraints. This study which was conducted in the University of Nairobi sought to analyze constraints that influence research productivity in the university.

Automatic recognition of bangla sign language using artificial neural networks (anns) for deaf and dumb to bridge the communication gap

Sign Language is the mode of communication among the deaf and dumb. However, integrating them into the main stream is very difficult as the majority of the society is unaware of their language. So, to bridge the communication gap between the hearing and speech impaired and the rest in Bangladesh, we conducted a research to recognize Bangla sign language using a computer-vision based approach. To achieve our goals we used Artificial Neural Networks to train individual signs.

Health care data analytics for adaptability in e-health care networks

Health is the essential part of human that individual has to feel, perceive and act effectively. And it is required to provide correspondent ways for proper health care delivery in real time manner. The arrival of new technologies especially the Internet of Things (IoT) Strengthen the health care system through Wireless Sensor Network (WSN). In the current health care environment the IoT enables to connect different stakeholders in the health care system like patients, physicians, hospital, emergency unit and patient well-wishers etc. regardless of their current location.

An efficient design of dynamic viterbi decoder architecture

The emerging applications of wireless networks enforce new challenges in design of algorithms and communication protocols. In such scenario of challenges, coding for error control has be- come extremely important to provide robust communication and maintain quality of service. One method to improve Bit Error Rate (BER) while maintaining high data reliability, is to use an error correction technique like the Viterbi algorithm. The Viterbi algorithm provides an efficient method for Forward Error Correction (FEC) that improves channel reliability.

Water quality, quantity and accessibility assessment: volcanoes national park region experience in Rwanda

This study ‘Water Quality, quantity and accessibility Assessment: Volcanoes national park region experience in Rwanda’ established the ways in which water is used, the level of demand, the level of supply, water quality, water quantity and accessibility around Volcanoes nation park of Rwanda. It has been hypothesised that there is a very high demand for water, lower lever of access due to population pressure and limited water sources.
