Induction heating is a non contact method of heating a conductive body by utilizing a strong magnetic field supply frequency 50Hz or 60Hz. Induction heaters incorporate a coil directly fed from the electric supply typically for lower power industrial application where lower surface temperatures are required. The aerospace power frequency for specialized induction heaters operated 400 Hz. Induction...
Image files contain considerable amount of redundant and irrelevant data and image compression algorithms can be used to overcome this. In this work, Wavelet Transform based compression algorithm is employed. Haar and daubechies wavelets are utilized in this proposed work for the decomposition of the medical image and the decomposed images are encoded using the schemes such as Embedded Zero wavelet,...
In cryptographic applications, the data sent to a remote host are encrypted at the source machine using an encryption key and then the encrypted data are sent to the destination machine, where it is decrypted to get the original data. Thus the attacker will not have the encryption key which is required to get the original data and so a hacker can do nothing with any cryptographic system. Reprogrammable...
Big data is a broad term for data sets so large or complex the traditional data processing applications are inadequate. Challenges include analysis, capture, data duration, search, sharing, storage, transfer, visualization, querying and information privacy. The processing and storage of big data although made efficient and easy by hadoop, there are two things to be considered, a storage part (Hadoop...
We present in this paper a single image dehazing method which is based on one dimensional linear filter. The objective of this research is to defog any type of foggy problem by using our algorithm, based on mean enhancement methodology and adaptive histogram equalization method. We are using YCbCr model in our work. The luminance image is used to remove the fog and showing the clear image objects...
Microstrip antennas generally prefer to printed antennas used for narrowband range at ultra-high frequencies and microwave communication. There are generally three basic methods of design microstrip antenna whose names are transmission line, cavity & full-wave model. This paper we use here the transmission line model for designing hexagonal shape having ground cut microstrip patch antennas. The...
Bioelectronic sensors manufactured by means of semiconductor technology have drawn attraction to the researchers as it expands its applications to many areas like defence, medical, food security, environmental and biotechnology. The basic theoretical principle of enzyme modified field effect transistor (ENFET) used as bioelectronic sensor, operating principle of ENFET, its modelling, a brief introduction...
As far as the asset reliability is concerned the Condition Based Maintenance is a major issue. The old maintenance strategies like break-down & preventive hold not good any time for many production systems. To create competitiveness & sustain in market CBM is a good tool. Rolling element bearing is a major component of machinery which is very prone to failure. Researchers have proposed many...
In this paper, a comparative study of different artificial Intelligence (AI) and hybrid AI approaches is presented. Total time of operation of directional over current relays (DOCRs) can be reduced, and also maintained the coordination constraints, and that will be done by selecting the optimum values of time multiplier setting (TMS) and plug setting (PS) of DOCRs. Towards this goal, different optimization...
The electrical industry is growing tremendously. Various types of load which are to be supplied constantly for economic growth, but the demand cannot be fulfill with limited central generation hence the distributed generators can be very beneficial option for that. Distributed generation is also an interesting topic for researchers as it gives other benefits like loss reduction, voltage profile improvement,...
This paper presents a system network analysis of a private firm having 54 MW generations and distribution level at 11kv/3.3kv/0.415kv and having an expansion of 66MW generation at the distribution level at 11kv/3.3kv/0.415kv. Load flow analysis, short circuit analysis and motor starting analysis are presented. Short circuit analysis of ETAP results is compared with manual calculation. Comparative...
Nowadays, solar power becomes one of the most suitable renewable energy source for power generation. In practice, inrush current is produced in grid connected transformer(s) during routine switching process of solar power plant. This inrush current effects to winding of transformer as well as produces harmonics and power quality issues. In this paper the calculation of inrush current and its effect...

Orthogonal...
A stable ranging localized network can be constructed by using the relative speed of the node pair, and the direction of motion of nodes. The network topology remains constant if the nodes move with same speed and in same direction. The direction of the NCS (Network Co ordinate System) by using proposed system is consistent when compared to [1]. The LRG (Local Reference Group) selection depends on...
