Abstract

We consider two tree-based indexing schemes that are widely used in practical systems as the basis for both primary and secondary key indexing. We define B-tree and its features, advantages, disadvantages of B-tree. The difference between B+-tree and B-tree has also been discussed. We show the algorithm, examples and figures in the context of B+-tree.

Keywords:Indexing Schemes, Primary key, Secondary key, B-tree, B+-tree.

Abstract

The present paper describes how the microcontroller works in the transmitter section of wireless system. In last 40 years a silent but rapid revolution as far as electronics computing communication and control are concerned. Proof of this statement would be available in mobile handset, MP 3 player, automatic washing machine, microwave oven, portable digital blood pressure measurement and many more medical instruments, billing system in STD phone etc. This list is enomorous and growing exponteally. All these are possible because of usage of Microcontroller and having a PC which involves from microprocessor. Temperature is certainly among the most commonly measured parameters in industry, science, and academia. Recently, the growth of wireless instrumentation technology, along with some clever innovations, has provided new ways to apply temperature measurement sensors combined with personal computers to collect, tabulate, and analyze the data obtained

Keywords:Microcontroller, Temperature controller, CAN, flags, Buffer,ADC,Step response

Abstract

This paper presents a proposed and applicable optimization algorithm based on the evolutionary algorithm to solve an environemental and economic Dispatch (EED) problem. This problem is seen like a bi-objective optimization problem where fuel cost and gaz emission are objectives .in this method, the optimal Pareto front is found using the concept of corridor observation and the best compromised solution is obtained by fuzzy logic. The feasibility of this method is demonstrated using power systems with three generation units, and it is compared with the other evolutionary methods of Optimization Toolbox of Matlab in terms of solution quality and CPU time. The simulated results showed that the proposed method is indeed capable of obtaining higher quality solutions in shorter computational time compared to other evolutionary methods. In addition the other advantage is that our approach solve in the same time a unit commitment problem and it can used with n-generation units.

Keywords:bi-objective,corridor observations, Evolutionary algorithm, fuel cost, gaz emission, optimal PARETO front, optimization

Abstract

In this paper, methods involving derivatives and the Mellin transformation are employed in obtaining finite summations for the H -function of two variables and certain special partial derivatives for the H -function of two variables with respect to parameters.

Keywords:Derivatives, Partial derivatives, H -function of two variables, Mellin transformation. (2000 Mathematics Subject Classification: 33C99)
