An application of the simulated annealing (SA) method to solve the multi-area unit commitment problem (MAUC) is presented. The objective of the multi area unit commitment problem is to determine the optimal or near optimal strategy for generating units located in multiple areas that are interconnected via tielines and joint operation of generation resources can result in significant operational cost...
This paper presents a generalized method of as Single term Haar wavelet series (STHWS) for solving time varying singular systems. This new approach provides a better effectiveness to find discrete solutions of different order time varying singular systems for any length of time t. This is a direct method and can be easily implemented in a digital computer.
The integration of neural networks and fuzzy inference system could be formatted into three main categories: cooperative, concurrent and integrated neuro-fuzzy models namely fuzzy associative memories fuzzy rules extraction using self-organizing maps and systems capable of learning fuzzy set parameters. Mamdani and Takagi-Sugeno type integrated neuro-fuzzy systems were further introduced with a focus...
A simulator in order to calculate the rate of the reaction in the methanol oxidation to formaldehyde process is presented in this paper. Here the Radial Basis Function Network is used to model the process. To choose an optimum number of hidden neuron we use an algorithm called Minimal Resource allocation Network. It recruits hidden neuron based on the novelty of the input data. The training data were...
The flue gas monitoring plays a vital role in thermal power plants as these emissions contribute to the majority of air pollution and global warming. Hence an intelligent sensor can be used in place of gas analyzer which is economical as well as provides information regarding the flue gas emissions based on the color of the furnace flame. The intelligent sensor is capable of classifying the flame...
Cryptography is the practice and study of hiding information. Cryptanalysis is the study of how to crack encryption algorithms or their implementations. This paper describes an effortless method of a cryptanalyst for a knapsack cipher. The describing method is based on simple programming and calculations to crack the knapsack cipher.
Petri nets generating all the 2^n binary n-vectors as their marking vectors are not only of theoretical interest but also are of practical importance. In this note, we demonstrate the existence of a disconnected 1-safe Petri net whose reachability tree is homomorphic to the n-dimensional complete lattice L_n. This makes the problem of characterizing the 1-safe Petri nets that generate all the binary...
E-mail is one of the most popular and frequently used ways of communication due to its worldwide accessibility, relatively fast message transfer, and low sending cost. The flaws in the e-mail protocols and the increasing amount of electronic business and financial transactions directly contribute to the increase in e-mail-based threats. Email spam is one of the major problems of the today‟s Internet,...
A soft sensor tries to estimate difficult to measure quality parameters from the knowledge of easy to measure online process variables. Empirical approach of soft sensor development has gained much popularity recently due to availability of huge quantity of actual process data stored in the industrial database. In this work a soft sensor based on back propagation neural network has been developed...
Most of the mathematical model of industrial applications have very high order,implementation and computation of such system is complicated and time consuming so there is an increasing need for obtaining suitable low order approximations of such systems. Low order models result in several advantages such as reduction in computational complexity and easy analysis of original system structure. This...
The growing popularity of mobile and hand held devices ignited the growth of wireless networks over the past years. Wireless data communications have transformed not only the business world but also the human society by improving efficiency, flexibility, convenience, and above all productivity. Wireless Local Area Networks (WLAN) typically emulate the wired networks traditional hub-spoke configuration...
Fruit grading technique will rank the images using their shapes, color and outer look. For that we present an improved watershed segmentation method based on multi-scale edge detection. Multi-scale edge detection method which is the weighted combination of morphological operations and it applied to fruit Image. First the image is given to multi-scale edge detection method and the result is given as...
The increasing amounts of three-phase squirrel-cage induction motors over the years are fed by variable-speed drives. In such a machine high frequency generation is caused by the high carrier frequencies of the pulse-width modulation, the associated short rise times of the IGBT output, and the reflected waves from the motor terminals. EMI is also produced by the harmonics which are generated by the...
In this paper, Iterative Learning Control approach for tracking trajectory is presented. The paper includes a general introduction to ILC and a technical description of the methodology. Iterative learning control (ILC) is a learning technique used to improve the performance of systems that execute the same task multiple times. Learning transient behavior has emerged as an important topic in the design...
One of the most recent and most intense efforts in control theory deals with handling systems whose behavior of interest is determined by interacting continuous and discrete dynamics. This approach can be applied not only to intrinsic hybrid processes but also to other systems as for example continuous processes with supervisory logic, multi-model control systems, switching control, etc. In this paper,...
Image fusion is an integral part of many existing and future surveillance systems. Due to the limited depth-of-focus of optical lenses (especially such with long focal lengths) it is often not possible to get an image which contains all relevant objects in focus. One way to get an everywhere-in-focus image is to fuse the images of the same scene which are taken with different focal settings. This...
Among the Artificial Intelligent technique, Neural Network 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 , in order to improve the controller easier to construct, simpler and better performance. To verify these goals, the system simulated based on Matlab Simulink...
Image segmentation is an important step in image processing. Most of the segmentation methods are parametric and the results of segmentation depend on the correctness of the estimated parameters. In case of supervised segmentation, a priori knowledge is needed for successful segmentation. So, nonparametric and unsupervised segmentation method is used when a priori information is not available. Kohonen's...
Increasing volume of web has resulted in the flooding of huge collection of web documents in search results creating difficulty for the user to browse the necessary document. Clustering is a solution to organize search results in a better way for browsing. It is a process of combining similar web documents into groups. For web page clustering, terms (features) can be extracted from different parts...
Power consumption of nodes in ad hoc networks and fixed network is major issue in current world. The lifetime of network will be improved by suitably reducing the requirement of power for connections. There is a challenge to provide QoS solutions that operate seamlessly over wired-wireless domains and maintain end-to-end QoS with user mobility. In this paper we have proposed different QoS Multipath...
