Enterprise Resource Planning (ERP) can provide benefits of cross-organization integration through embedded business process, if successfully implemented. But it is too difficult to implement an ERP system in an organization successfully. Therefore, techniques required to increase the successful implementation rate in ERP projects. On the other hand, the MIS departments of industry sectors typically provide Decision Support System (DSS). More recently, ERP and related systems are incorporating DSS tools and technologies. In this article, a new method to create parallel flows that make different use of DSS in ERP systems is proposed. To illustrate this new method, a case of parallel flows has been shown. The use of parallel flows leads to improve the main workflow in ERP systems and it will consequently increase the percentage of success of ERP in an organization.

Control theory for linear processes often acts as a suitable scientific method with powerful techniques for designing and analyzing the controllers which its results in the optimization of energy and better function of the system. In this Paper the linear parabolic solar power plant has been modeled via system identification, and Non linear model and its equations Shiraz Solar Power Plant is a test pilot in this paper and its operational steps are studied from analytical and experimental aspects. In the proposed model the input and output have been assumed to be the entering oil flow and outgoing oil temperature. Therefore performance cycle and parameters have been analyzed, according to available data from Shiraz solar power plant.

It is generally assumed that copper rotor bars can outstand aluminium rotor bars in terms of better performance in losses reduction or money saving. This paper presents the comparison of the aluminium rotor bar and copper rotor bars designed by using FEM software to simulate the 0.5HP AC induction motor. The 0.5HP three phase induction motor is compared in terms of plot magnetic potential lines, eddy current density, magnetic flux density and lastly magnetic field strength. Analysis shows that the copper rotor bars have good performance in all the area that was investigated and thus lower the losses especially core and copper loss in the induction motor.

Infant cry is a multimodal behavior that contains a lot of information about the infant, particularly, information about the health of the infant. In this paper a new feature in infant cry analysis is presented for recognition two groups: infants with pain and normal infants, by Mel frequency multi-band entropy extraction from infant's cry. In signal processing stage we made pre-processing included silence elimination, filtering, pre-emphasizing. After taking Fourier transform, spectral entropy was computed as single feature of signal. In classifying stage, by training artificial neural network, correction rate of recognition was obtained 66.9%. In order to enhancement in results, we used Mel filter bank. Entropy of each sub-band constitutes elements of next feature vector. We used PCA analysis for reducing in dimension of the recent feature vector. After ANN training, correction rate improved to 88.5%. So multiband spectral entropy enhanced results in salient correction rate.

This work demonstrates the possibility of using the available-in-market appliances in a DC-distribution system. This demonstration also represents an alternative migration from AC-distribution to DC-distribution. DC-distribution has been shown to be more efficient and provided good power quality in a distribution system. The power supply technology in the modern appliances makes the possibility of an appliance to be used in either both AC-distribution and DC-distribution without any modification. Appliances are tested by using an AC-source as the base-line and then the test replaces the AC-source by a DC-source.

A simple inexpensive technique is presented in this paper for sensorless control of brushless DC motors (BLDCMs) based on the back emf (BEMF) measurement. Through the presented algorithm, the point at which the power is switched on or off to the phases, is calculated with accuracy in simple mathematical equations by capturing samples of the BEMF which are mapped back to reference values. The sampling utilizes the analog to digital converter (ADC) implemented in microcontrollers which eliminates using filters, comparators, and the delays called through look up tables after the detection of the zero crossing point (ZCP). Experimental results are also given to verify the proposed algorithm.

During the software development life cycle, testing is highly needed to assure the quality of the software process and product. For many years, researchers and practitioners came-up with a variety of software tools to automate the testing process. In this paper, we will classify and distribute a set of testing tools over the types of testing (testing methods) for three types of software products (web application, application software, and network protocol). However, the outcomes of this classification are dedicated to the re-searchers and practitioners in software testing to know which types of testing have no or limited automated tools.

For decades both material scientists and engineers have sought to find an artificial equivalent of muscle to help in the development of new transducer technology. A specific class of electroactive polymers (EAP) known as ‘dielectric elastomers’ have demonstrated most potential because they can undergo large deformation, have a high energy density and a relatively fast response. This contribution introduces dielectric elastomers and discusses the research challenges that need to be addressed before the full potential of the actuator technology can be realized.

A numerical simulation has been done using CFX11.0 to study the effect of an airfoil probe installed at the leading edge of first stage stator in a compressor. Combination of structured and unstructured grids has been used during the calculation. Result shows that blade loading with and without probe is obviously different at 50% height of blade, while the effect at 20% and 80% height of blade is not obvious. The result has proved that probe indeed has an effect on performance of a compressor, and especially on a compressor with a high speed, high pressure ratio .A corresponding test will be done to validate the result and for a further study.
