Understanding this subject can help us to implement ERP systems properly in developing nations. This research showed that in developed and developing countries \"Change Management\" was most important factor and in developed countries \"Country-related functional requirements\" factor was less important factor and \"Fit between ERP and business/process\" was the least cited factor among developing nations. In last it concluded that national culture of developing countries has an impressive effect on ERP implementation in these countries. In other hand developing countries companies more depend on ERP vendors in compare to developed countries companies. In addition it seems developing countries underestimate business process reengineering (BPR) and fit between ERP and business/process factors in comparison with developed countries.","PeriodicalId":433032,"journal":{"name":"Int.

In this case, the secret message will be looked as plaintext with digital signature while the cover is a coloured image. Then, the results of the algorithm are submitted to many criteria in order to be evaluated that prove the sufficiency of the algorithm and its activity. Thus, the proposed algorithm for this research can be divided into two main parts: hiding the text of the sender, and extracting it by the receiver. Moreover, part can be divided into many procedures done by the program Delphi 5.","PeriodicalId":433032,"journal":{"name":"Int. J. Adv. Comp.

The main target is to find a suitable controller that minimizes the performance index of error signal under the robust stability and robust performance conditions. Different types of performance indexes are used to have optimal PID controller such as IAE, ISE, and ITAE. In this paper, all the three indexes are used to estimate the performance of the mixed H2/H∞ PID controller using PSO under the uncertainty and disturbance. The results show that the ISE was the best to use with disturbance condition to get robustness.By testing two different control systems with the typical characteristics such as time delays and system with RHS pole and zero, the proposed algorithm has been demonstrated to have good results with parameters uncertainty and disturbances.","PeriodicalId":433032,"journal":{"name":"Int.

The proposed technique minimizes largely the plant modeling errors resulted from simplification made to obtain a linear discrete time plant model. In addition, due to the repetitive control action, this digital control scheme can minimize the steady-state error and periodic distortions caused by nonlinear cyclic loads. Hence, the Total Harmonic Distortion (THD) will be reduced. This technique utilizes a switching frequency greater than the sampling frequency, yielding additional minimization in the plant modeling errors. As the sampling frequency is less than the switching frequency, it is possible to implement this controller on a low speed microcontroller. Plant model and theoretical analysis of the control scheme are discussed. Simulation results are presented to verify the performance of the proposed approach under different load conditions.","PeriodicalId":433032,"journal":{"name":"Int. J. Adv. Comp.

Conventionally, the syntactic homogeneity of the resource description in each repository is used for match making and for identification of the required resource. Of late, detecting the semantic homogeneity of the resource description is also coupled with syntactic matching for the purpose. However, detecting semantic homogeneity requires complete description of the associated resource. We propose here an approach that is based on employing complement classes to early reject those resources that lack the semantic matching, thereby yielding efficient discovery of the required resource. To the best of our knowledge, ours is the first attempt at proposing Complement Class based semantic match making algorithm for detection of the resources.","PeriodicalId":433032,"journal":{"name":"Int.
