The risk-cost analysis for safety critical systems of nuclear power plants (NPPs) are very useful in safe, economical and effective design and operation of such plants. The issue of risk effectiveness versus associated costs is an optimization problem where two separate cases can be considered. First one is the cost minimization while the performance or(More)
Wireless sensor networks (WSNs) consist of lightweight devices with low cost, low power, and short-ranged wireless communication. The sensors can communicate with each other to form a network. In WSNs, broadcast transmission is widely used along with the maximum usage of wireless networks and their applications. Hence, it has become crucial to authenticate(More)
With the development of internet and the coming of the post-PC era, the embedded systems is becoming the centre of interest in the current IT industry and exhibiting broad potential market. In the meantime, the access of embedded systems into the internet has become an important direction of the present internet development. By analysing the adoption of(More)
Text in video and images is an extremely valuable feature to extract brief knowledge of video or image. But sometimes those text components feel unnecessary, and so various methods have been proposed till a day to detect, and remove the text out of video. This paper performs an extensive survey of various techniques available for text detection and removal(More)
—This paper presents an architecture for the fast computation of the 8×8 two dimensional (2D) Inverse Discrete Cosine Transform. The proposed method is the permanent storage of the Basis Matrices of the 8×8 2D Discrete Cosine Transform (DCT). The sparseness property of the 2D DCT coefficient matrix, the computational time decreases as the number of nonzero(More)
The Indian Materials Database (IMDB) is a national project aiming to develop a database through compilation of materials property data available in different laboratories in India. The database contains data on mechanical, corrosion, nondestructive evaluation, thermal and optical properties of a wide variety of materials. Selecting the appropriate data(More)
Diabetic Retinopathy (DR) is a persistent disease which affects retinal blood vessels of diabetic patients leading to lack of vision. New blood vessels start appearing at the final stage of this disease termed as Proliferative Diabetic Retinopathy. There are many techniques that helps to diagnose DR and detection of new vessels in retinal fundus images.(More)
Protocols are required to optimize network performance based on energy resource due to limited battery power in Mobile Ad hoc NETwork (MANET) nodes. This paper proposes a modified Protocol for MANET to achieve energy efficiency and reliability. The probability for a sleep node is determined by the parameter metric of Packet Delivery Ratio at the destination(More)
