Mehdi EL Aichar, Imen Labidi and Slim Benyacoub
A study of the community structure of dung beetles was conducted between May 2010 and April 2012 in the El Kala National Park in north-eastern Algeria, three sites were chosen according to soil type and altitude (Boumalek, Brabtiia and Djebel el Ghorra). Monthly trapping conducted according to a standardized protocol (CSR), allowed the capture of 16893 beetles belonging to 25 species.Our results show that the peak of activity during the two years sampled was observed in late spring in Brabtia and Boumlalek and early summer in Djebel el Ghorra. The three stations have almost the same composition and equitably share the food resource. Some species showed a preference for one type of soil. The abundance of dung beetles may be due to the availability and abundance of food resources but the community studied showed no pattern of response habitat selection.

A Mathematical Investigation on the Optimum Design of the Nose-Deck System in Incrementally Launched Bridges
Mohammad Reza Hirmand, Ehsan Rahimi, Amin Moghadam and H. Tajmir Riahi
Bridge construction by Incremental Launching Method (ILM) is performed by building deck segments on the ground near one of the abutments and then incrementally pushing them forward on constructed piers. Construction by this method causes temporary stresses in structural elements that are different and more critical than those in service time. Therefore, an appropriate method should be employed in order to prevent losing the advantages of this method due to overdesigned structural members. So far, researchers and engineers have proposed different methods for this purpose. Among them, using a nose-deck system, especially for prestressed concrete bridges, is now very common and has been accepted as the standard method. Geometrical and mechanical characteristics of the launching nose are determinant to the temporary stresses at the construction time. Therefore, it is necessary to use an optimal design for the nose-deck system. In this paper, a Finite Element model of the launching bridge is investigated to present a simplified model for the Nose-Deck system called as “semi-infinite beam model”. The presented model is employed to study the optimal design of Nose-Deck system based on mathematical optimization approach, indicating the simplicity and efficiency of the model for practical applications.
Keywords: Incremental bridge launching, Nose-Deck system, mathematical optimization, finite element method.
A Study of Tomato Juice Production
Tomato is considered one of the most important vegetables which grow in Jordan. Tomato is of a great nutrition value as fruits, but it differs from typical fruits in its low sugar content which makes the solid substance in it low. This paper aims at investigating the possibility of producing juice from tomato. The tests results have proved that the stability of the juice essence is possible when it is stored at room temperature of (16 to 22 oC), and at 32 oC for eight weeks as indicated by sensory, chemical, physical, and microbiological testing. The study also shows that the results of the sensory evaluation may determine the degree of admiration of tomato juice production before and after being stored which emphasizes the technical benefit of its production.
Generalized Linear Models: Choice of Appropriate Link Function and Model Selection Tools
Mudassir Ahmed and Ghausia Masood Gilani
Generalized Linear Models are the extension of the popular General Linear Models. The generalization process includes the transformation of non-linear functions into linear functions using appropriate link functions e.g. Identity, LOGIT, PROBIT and C-LOG-LOG. The selection of appropriate link function to model the binary responses still remains a challenge. The selection of inappropriate link function not only ignores the shape of the underlying tolerance distribution but also provides the regression estimates that may be inconsistent and vague. The frame work for the selection of appropriate link function using Regression Error Specification Test (RESET) for generalized linear models using real data on Maternal Health from MICS 2007-08 has been discussed keeping in view the information provided by the model selection tools like Deviance, Pearson Chi-Square, Log Likelihood and prediction power of the model.
Keywords: Generalized Linear Models, Tolerance Distribution, RESET, Link Function, LOGIT, PROBIT, C-LOG-LOG and, MICS 2007-08.

Muthana Khallil Ibrahim
In this paper, we present an optimization method based on Invasive Weed Optimization (IWO)) algorithm for uniform planar antenna array antennas to acquire a narrow beam width with minimum relative Side Lobe Level (SLL). Two different cases have been studied. The fist one is a fixed 256 (16x16) -element simulated for SLL suppression. The second one have1024 (32x32)- element. Both cases show the simulation results of the proposed IWO algorithm for uniform planar antenna array are compared with Particle Swarm Optimization (PSO) to illustrate the effectiveness of our proposed method. Comparison results show the IWO has a superior performance compared with the PSO for the antenna arrays optimization.

A Decision Support System Designed to Increase the Efficiency of Financial Institutions
Javad Poorshahriar and Mostafa Hojati Avini
There are three issues to evaluate the efficiency of financial institutions and banks clients; what should be measured? How should be measured? How can be compared the occupations together? And a model assumed to answer these questions is, it is not possible to evaluate people because they have different characteristics such asaccuracy in work, working quickly, and proper communication and etc, but their occupational characteristics will be involved. In other word, An employee who works as "IT security expert" in comparison with a employee who works as " educational expert" have significant differences in term of the sensitivity, complexity, level of knowledge and skills are required for occupation. In this article tried to first gain comprehensive model. In order to obtain the criteria used in this model, some individual criteria as well as occupational criteria can be selected after library research and then it was approved by presenting a questionnaire to experts. According to this model, compensatory decision-making methods TOPSIS have been used to evaluate individual and occupational criteria and use Fuzzy AHP to determine the criteria.
Keywords: Performance evaluation, efficiency, occupation, decision support system, TOPSIS, Fuzzy AHP.
Post-Newtonian Gravitational Radiation from Orbiting Masses
E. El-Houssieny, F. A. Abd El-Salam, M. Rassem and M. N. Ismail
Previous studies are limited to evaluate the post-Newtonian effects up to 1st order terms of the post-Newtonian approximation. When higher order terms in the post-Newtonian approximation are considered, (spin and higher multi-pole effects) it may be of significant to get results accurate enough for comparison with future observational data, especially for neutron stars and Kerr black holes. For these compact objects, it is estimated that the spin-orbit and spin-spin coupling are of second order in the post Newtonian approximation. Therefore, one of the main tools of analyzing and obtaining gravitational wave forms, generated from coalescences of compact binaries, is the post-Newtonian approximation. In the present work, the 2nd order formulae for waveform and the luminosity of gravitational waves have been derived, taking into consideration the spin effects.

The world is witnessing a growing thirst for oil. As the industrial era is evolving at a continuous rate, our existence has become more dependent on this substance as a means of survival. What has been apparent throughout this evolution of industries is the reliance on production lines in the creation of various products and services. Therefore, it comes as no surprise an industrial engineer's aim is to optimize systems within production lines in the oil industry. Several methodologies were researched in order to discern a suitable approach. The methods researched include the heuristic method, mathematical programming, computer simulation, and feasibility studies. Through computer simulation, one can easily manipulate different parameters in order to propose an advisable scenario that would optimize a company's production line. Arena®, a simulation software provided by Rockwell, will be used to design and simulate production lines in a company, along with feasibility studies to aid in the successful accomplishment of the objectives set. In this article, modelling, simulation and analysis of a Refinery’s crude oil production line was contributed for the company’s future benefit.
