Music is a universal language that does not require an interpreter, where feelings and sensitivities are united, regardless of the different peoples languages, The proposed system consists two main stages: process extracting important properties using linear discrimination analysis (LDA) This step carried out after initial treatment various procedures to remove musical lines, second stage descr...

Bat algorithm (BA) has been widely used to solve optimization problems in different fields. However, there are still some shortcomings of standard BA, such as premature convergence and lack diversity. To this problem, a modified directional bat (MDBA) is proposed paper. Based on the (DBA), individual optimal updating mechanism employed update bat’s position by using its own solution. Then, an e...

the purpose of this study was to estimate relative potential hazards to birds and bats from wind developments in texas. we compiled lists of rare, threatened, or endangered species, along with their respective ranges in texas. using a geographic information system (gis), we calculated a potential hazard index (phi) for 31 bird and ten bat species based upon the percentage of known or observed s...

Nature inspired algorithms are the most popular and robust algorithms for the optimization of the real world problems like pitch control of an aircraft system. This paper introduces Bat algorithm and Differential Evolution technique for the multi-objective optimization based designing of the fractional order PID (FOPID) and integer order PID controllers. The optimized values obtained from the t...

In this research paper, an algorithm is developed to produce better contrast enhancement which is inspired from nature and calculates the upper and lower limit for each sliding window. These upper and lower limits are used to calculate the local mean and global mean. It is based on contrast objective function; this is parabolic logarithmic threshold function. The results show that, the method i...

Abstract. In this communication we suggest a formulation of the optical conductivity as a convolution of an energy resolved joint density of states and an energy-frequency labelled transition rate. Our final aim is to develop a scheme based on the augmented space recursion for random systems. In order to gain confidence in our formulation, we apply the formulation to three alkaline earth titana...

This paper proposes a novel quantum-behaved bat algorithm with the direction of mean best position (QMBA). In QMBA, the position of each bat is mainly updated by the current optimal solution in the early stage of searching and in the late search it also depends on the mean best position which can enhance the convergence speed of the algorithm. During the process of searching, quantum behavior o...
