Measures for Evaluating the Decision Performance of A Decision Table with Variable Precision in Rough Set Theory
7-14
Abdel- Fatah. A. Azzami
Abstract:
Approximation accuracy and consistency degree were employed to evaluate the decision performance of a decision table. We noticed that these two measures cannot give elaborate depictions of the certainty and consistency of a decision table when their values are equal to zero. To overcome this shortcoming, one will use a variable precision rough set model to get a new approach for basic rough set concepts. Some examples are given and comparison between the result of new concepts and similar approximation are given.
Keywords: Rough set; variable precision; lower and upper approximations; decision rule.

Time Modeling in Educational Chat Room
27-35
Abstract:
This paper discussed a model for monitoring the student activity during the educational chat session with his colleagues about a particular topic assigned to discuss it during a particular session. Monitoring is done through time modeling by evaluating the effective use of time by the student and exploited to the largest possible period of time in the session activity. This method is used to improve the general idea of the educational Chat among students and make it formalized which will lead to make the students behave more seriously with a session chat. Experiments performed as well as previous studies have produced a mathematical equation based on the parameters calculated by recording the time periods carried out by the student activities. Equation model called time and equals to: Time Model = 46.813 + 0.574 * (Posts Count / Complete Session Time + TIDL) All these parameters are discussed in the following sections
Keywords: Time, Student, AVCM, Post, Activity.

Numerical Solution of Singularly Perturbed Two-Parameters DDE using Numerical Integration Method
36-44
Mohamed S. M. Bahgat and M. A. Hafiz
Abstract:
In this paper, we present numerical integration methods to solve singularly perturbed Two-Parameter delay differential equations (DDEs) of second-order in which the highest order derivative has multiplied by a small parameter ? and both the convection and reaction terms are with negative and positive shift. In this method, we approximate the terms containing negative and positive shifts using the Taylor series expansion. We employ the Taylor and Simpson numerical integration, which has solved easily by discrete invariant imbedding algorithm. Several test examples are considered by taking various values for the delay, advance and perturbation parameters.

Pillow Lavas of Rabat (Northwestern Moroccan Meseta): Transitional Geochemical Signature of Magmas set up in an Early Ordovician Extending Platform
45-57
Hassan EL Hadi, Abdelfatah Tahiri, Fernando Simancas, Francisco Gonzalez Lodeiro, Antonio Azor and David Martinez Poyatos
Abstract:
The Ordovician pillow lavas of Rabat (northwestern Moroccan Meseta) were emplaced in an epicontinental platform undergoing extension, related to the Gondwana breakup at Early Palaeozoic. The geochemistry of this Ordovician volcanism suggests a real homogeneity in the composition of sub-continental mantle and attests the enriched character of the mantle in LILE and LREE compared to HSFE, probably due to crustal components added during previous events of subduction. A genetic link with an Ordovician subduction is discarded, based on the geological setting, a continental extensive faulting fragmentation (continental rifting). This allow us to ascribe the negative anomalies in Nb-Ta of these pillow lavas to the partial melting of a lithospheric mantle enriched during an older subduction event, likely of Proterozoic age.

A Hybrid Technique for Persian License Plate Recognition Based on GRNN
58-68
Elham Karimi and Kaveh Kangarloo
Abstract:
Today, License Plate Recognition is used in Intelligent Transport Systems (ITS). Character recognition is the key step in license plate recognition. Mainly the Resolution of input images is low which impact on the performance of these systems. Many researches have been published in conjunction with license plate image enhancement but there is less work dealing with effective features to recognize characters in low resolution images. In this paper, a new hybrid technique for Persian license plate recognition based on Generalized Regression Neural Network (GRNN) is presented. In this method, the Local Binary Pattern (LBP) and wavelet features are extracted from high and low-resolution images. Then they are used to train the Generalized Regression Neural Network. This network is used to determine the relationship between the LBP and wavelet features of LR and HR images. LBP can present the local feature of image effectively and its computation is easy and quick. Wavelet coefficients are used to distinguish between images that have similar LBP histograms. The output of the Generalized Regression Neural Network is the features of high-resolution images. To improve the flexibility of the presented method; a similarity function is used. Performance of the presented method was evaluated using software. The experimental results indicate the effectiveness of the proposed method.
Keywords: License Plate Recognition; Generalized Regression Neural Network; Local Binary Pattern; Wavelet; feature.

The Impact of Application of Business Process Reengineering on Improvement the Institutional Performance Effectiveness A Field Study on the Jordanian Pharmaceutical Companies
81-98
Hasan Yasien Tuama and Laith Abdullah Alqhiwi
Abstract:
This study aimed to identify the applying degree of Business Process Reengineering (BPR) in the Jordanian pharmaceutical companies and the impact of this application on improvement the institutional performance effectiveness in these companies. The study population consists of all managers (high management & middle management) distribution on (38) company and factory from the mentioned companies with (240) manager. To achieve the study objectives, a questionnaire has been prepared with (30) item. The validity of the tool has been examined by being presented to a set of referees. The reliability of the tool has been examined by using Cronbach’s Alpha Coefficient, the overall reliability coefficient of the tool has been (0.93). The study findings a number of results, including: 1. The applying degree of (BPR) and it's dimensions in the Jordanian pharmaceutical companies ranged between (high & middle) from the respondents’ perspective. 2. The level of (institutional performance effectiveness) and the effectiveness standards which used in the Jordanian pharmaceutical companies ranged between (high & middle) from the respondents’ perspective. 3. There exist a statistically significant impact at the significance level (a = 0.05), in general for the (BPR) dimensions (process redesign, innovation and renovation, and offering of new products) on improvement the institutional performance effectiveness in the Jordanian pharmaceutical companies. 4. There exist a statistically significant impact at the significance level (a = 0.05), for the (BPR) dimensions (process redesign, innovation and renovation, and offering of new products) on the standard (mission and objectives) in the Jordanian pharmaceutical companies. 5. There exist a statistically significant impact at the significance level (a = 0.05), for the (BPR) dimensions (process redesign, innovation and renovation, and offering of new products) on the standard (institutional domain) in the Jordanian pharmaceutical companies. 6. There exist a statistically significant impact at the significance level (a = 0.05), for the (BPR) dimensions (process redesign, innovation and renovation, and offering of new products) on the standard (institutional resources) in the Jordanian pharmaceutical companies. Upon the foregoing results, the study reached to a number of recommendations and suggestions.
