A novel Image Inversion based Two Level Histogram Equalization (IIBLHE) for contrast enhancement is proposed in this paper. In this method, the first level of equalization is carried out in such a way that the image is inversed first and then histogram equalization is applied; again inversed and the second level of equalization is performed by modifying the probability density function of that resultant image by introducing constraints. This technique of contrast enhancement takes control over …

The paradigm shift from 'data-centered pattern mining' to 'domain driven actionable knowledge discovery' has increased the need for considering the business yield (utility) and demand or rate of recurrence of the items (frequency) while mining a retail business transaction database. Such a data mining process will help in mining different types of itemsets of varying business utility and demand. We here present a set of algorithms for mining all types of utility and frequency based itemsets fro…

The objective of the Fuzzy Adaptive Control (FAC) is to tune the scaling factors of the direct fuzzy logic controller (FLC). In this novel approach output scaling factor of Fuzzy controller is tuned through adaptation mechanism. The idea is to have a control system that will be able to achieve improvement in tracking set point change and rejection of load disturbance. In this paper, the proposed Fuzzy Adaptive Controller is applied to a permanent magnet synchronous motor drive (PMSM). High perf…

In recent advancement in communication, it was made possible that many heterogeneous wireless networks can be made to operate in one wireless network by establishing standard for each wireless traffic. Slots allocation in such network is one of the challenges since each traffic has its own quality of service requirements. In this paper we present slot allocation algorithm for real time and none real time traffic of mobile WiMAX. Since the wireless link of the network is a function of time, the …

We present common fixed point theory for generalized weak contractive condition in symmetric spaces under strict contractions and obtain some results on Invariant Approximations.

The quality of the data being analyzed is a critical factor that affects the accuracy of data mining algorithms. There are two important aspects of the data quality, one is relevance and the other is data redundancy. The inclusion of irrelevant and redundant features in the data mining model results in poor predictions and high computational overhead. Feature extraction aims to reduce the computational cost of feature measurement, increase classifier efficiency, and allow greater classification…

Asymmetric Cascaded Multilevel Inverter (ACMLI) was widely studied. Various control strategies have been investigated. However, most of the reported control strategies not discussed how to determinate voltage levels, firing angle, switching-state and other parameters control design. This work was developed a universal algorithm to overcome the problems in the various number of H-Bridges and various DC voltages of ACMLI. The proposed algorithm based on combination theorem and matrix operation. T…

Among the Artificial Intelligent (AI) technique, Neural Network (NN) is emerging technology that is advancing rapidly and having impact on many scientific and engineering applications. In this paper, NN apply on Asymmetric Cascaded Multilevel Inverter (ACMLI), in order to improve the controller easier to construct, simpler and better performance. To verify these goals, the system simulated based on Matlab Simulink after the NN controller build using m-file program. The simulation results show t…

This paper deals with the tidings of cryptography in history, how it has played a vital role in World War -1, World War-2. It also deals with the Substitution, Transposition Cryptographic techniques and Steganography principles which can be used to maintain the confidentiality of computerized and none computerized information files.

Today search engines constitute the most powerful tools for organizing and extracting information from the Web. However, it is not uncommon that even the most renowned search engines return result sets including many pages that are definitely useless for the user. This is mainly due to the fact that the very basic relevance criterions underlying their information retrieval strategies rely on the presence of query keywords within the returned pages. Web Search Personalization is a process of …
