Presenting a Conceptual Model for Evaluation of Economic Development Programs in Iran
The present paper aims at evaluation of the first four economic development programs of Iran during years 1992 through 2008 by use of data envelopment analysis (DEA) method. Examination of non-parametric methods indicates that selection of decision-making units (DMU) efficiency depends on nature of data either cardinal or ordinal in both inputs and outputs. In the present research, to determine inputs and outputs coefficients the Atrophy Shannon model was proposed, then, according to the research conceptual model (OCRI) , independent variables ( inputs) and outputs ( rate of relative efficiency of each program in each year) were specified. Next, based on available variables inputs and outputs, and coefficients the major research model for maximization of the goal function was designed. Finally, for expansion of model some related applications were introduced. The main purpose of the current research is application of quantitative methods and instruments (mathematics) for evaluation of the economic development programs in Iran.

The Effect of Water Content of Waste Material on Gas Generation
Tri Budi Prayogo, Yutaka Dote and Tomoo Sekito
There are several physical, chemical and physiological factors in the environment that affect biodegradation of organic materials. The effect of the water content has been widely studied as a factor that influences biodegradation. This paper deals with the effect of the water content of waste material on gas generation that indicates the level of biodegradation. The purpose of this study was to clarify the effect of water content on biodegradation considering dry season condition in Southeast Asia region.
A batch experiment with organic material as the sample was conducted in an anaerobic condition. Six materials were used; rice, carrots, bananas, meat, chicken meat and fish, as substrate material. Each sample was dried using the freeze drying method to maintain a condition of zero water content. The condition of the water content for each substrate batch experiment bottle was 30% to 80%. Liquid inocula were added up to as much as 25% of the weight of each sample. The batch bottle was stored in an incubator at 30oC.
The results show that gas generation was increased with the increase in the water content. The result shows that Maximum Gas Generation Rate in every substrate was increased with an increase in water content and different rates at a water content of 80% was found in the different substrate. The critical water content for every substrate was the same value of 50%. It was shown that the gas generation was influenced by not only the water content but also the type of the material in the substrate.

The Effect of English - Arabic Code Switching on Teaching English Language and Literature at Mu'tah University
This study investigates the functions that the phenomenon of code switching show and the reasons that students of English language and literature at Mu'tah University switch from English to Arabic. The study compromises 15 male and female students at the department of English in Mu'tah University. There ages are ranged between (18-22). Student of English language and literature were chosen because of their assumed proficiency in English. The researcher used random sampling processing in choosing participants and collecting data. The finding of the study showed that students of English language and literature tend to use code switching for many reasons such as matching the sequence of talk, also it showed that there is an emphasize a direct previous message, to improve their English proficiency, to replace Arabic words that are considered taboo as English words seem less offensive, use English habitually and to deliver message briefly when learning. To conclude this, the study recommends that further research studies be conducted to confine the findings. This study recommends that we shouldn't have negative attitude toward code switching. More researches are recommended to find another motivations for code switching or to find out whether the period of exposure to English may influences the variation in reasons towards switching.

Improvement of Performance Parameters of Microstrip Antennas with Criss-Cross Metamaterial Based Artificial Substrate
Kirti Inamdar, Y. P. Kosta and S. Patnaik
In this paper, we present the design of a metamaterial based microstrip patch antenna, optimized for bandwidth and multiple frequency operations. A Criss-Cross structure has been proposed, this shape has been inspired from the famous Jerusalem Cross. The theory and design formulas to calculate various parameters of the proposed antenna have been presented. The software analysis of the proposed unit cell structure has been validated experimentally thus giving negative response of e and µ. Following this, a metamaterial-based-microstrip-patch-antenna is designed. A detailed comparative study is conducted exploring the response of the designed patch made of metamaterial and that of the conventional patch. Finally, antenna parameters such as gain, bandwidth, radiation pattern and multiple frequency responses are investigated and optimised for the same and presented in table and response-graphs. It is also observed that the physical dimension of the metamaterial based patch antenna is smaller compared to its conventional counterpart operating at the same fundamental frequency. The challenging part was to develop metamaterial based on some signature structures and techniques that would offer advantage in terms of bandwidth and multiple frequency operation, which is demonstrated in this paper. The unique shape proposed in this paper gives improvement in bandwidth without reducing the gain of the antenna.

Performance of Different Aggregates in Concrete Structures Located in Marine, Rural and Urban Environment in Argentina
C. Priano and L. Señas
Aggregates used in concrete of several structures located in Bahía Blanca city (Province of Buenos Aires, Argentina) were analyzed. Their petrographic and mineralogical composition was determined, as well as, the relation with the alkali-aggregate reaction. The reactive components were analyzed using X-ray diffraction and scanning electron microscopy. Coarse and fine aggregates of the analyzed structures show similar lithological composition. From a petrographic point of view they can be qualified as potentially reactives with respect to the alkali-silica reaction. Despite this, most of the studied structures are not affected by this pathology. Cases where the reaction was noticed are related to the use of a concrete type with high level of alkali and the microclimate in the surroundings of the affected structure. From the use cases, it was possible to establish that in some of the constructions there was not a proper material selection since potentially reactive materials were used, considering the ASR, without measuring the level of alkali content of the concrete or/and the environmental factors.

Performance of Clustering Evaluation Measures in Massive Online Analysis Framework
P. K. Srimani and Malini M. Patil
The present study aims at generation, validation and visualization of clusters in data streams using clustering algorithms under massive online analysis framework with different instance sizes. Data stream mining using clustering approach has gained lot of scope in the recent research. Clustering is one of the important data mining problem and clustering validation is a challenging task because of the ubiquitous nature of data streams. Though the cluster evaluation or validation is not well developed, but even then it is possible to compare the evaluation measures of clusters using two different algorithms in a massive online analysis (MOA) frame work. The evaluation part of the paper mainly aims at study of the 26 cluster evaluation measures. It is found that different validation measures may be appropriate for different clustering algorithms, it is necessary to have a focused study of cluster validation measures on a specified clustering algorithm at one time. Study reveals that different validation measures have been developed for evaluating the performance of clustering algorithms but the present work provide a guide line to select the most suitable validation measures for STREAMKM and CLUSTREAM algorithms in massive online analysis framework.

Review on Routing Protocols for Mobile Ad-Hoc Network
Khalid W. Al-Ani, Salman Yussof, Hussein M. Haglan and Hothefa Shaker
Mobile Ad-hoc Network (MANET) is a collection of mobile nodes that has no fixed infrastructure and can be rapidly deployed in any environment when needed. Nodes in MANET can be organized themselves randomly and are free to move in any direction. Hence, the topology of this network is changing frequently and dynamically. Due to the attribute of dynamic topology, routing in MANET is a lot more difficult than routing in a fixed wired network. In this paper, we provide an overview of routing protocols by presenting their characteristics and functionality and also describe the limitation for each of them.

Improving the Multibiometric Recognition Based on Fuzzy Vault Scheme Using Multiple Polynomials
Gandhimathi Amirthalingam and Radhamani.G
Single modal Biometric systems stumble upon a noisy sensor acquisition, non-universality performance rate and a variety of security problems. The multimodal biometric system may be inclined to different attacks like a man-in-the-middle attack, Trojan horse attack, collision attack and replay attack. Template security and privacy are essential issues to be addressed for assuring successful biometric deployment. In this paper, a method to face and ear multimodal biometric template security is proposed. The extracted feature set of multimodal face and ear are applied to the multi biocryptosystem fuzzy vault technique using multi polynomial to avoid the possible degradation of the security. Template security and accuracy of multibiometric system fuzzy vault depends on the infeasibility of the polynomial reconstruction problem. The experimental results of the proposed method are evaluated using False Matching Rate (FMR) and Genuine Acceptance Rate (GAR) with the degree of polynomials. The performance of suggested method shows the promising growth in the multimodal biometric recognition and template security.

Investigating the Ultrasonic Vibration of Quench Environment before Cryogenic Heat Treatment
Kamran Amini, Amin Akhbarizadeh, Sirus Javadpour and Sina Matin
In this study, the effect of the ultrasonic vibration of the quench environment before the deep cryogenic heat treatment on the microstructure, hardness and wear behavior of the 1.2082 tool steel was investigated via the scanning electron microscope (SEM), X-ray diffraction (XRD), hardness and pin-on-disk wear test. For this purpose, the samples were quenched in water and oil while the quenching environment was being vibrated ultrasonically. The ultrasonic vibration affects the retained austenite percentage and subsequently changes the microstructure and hardness of the samples. Results show that the ultrasonic vibration induces a higher content of martensite into the steel structure. Hence, a more uniform carbide distribution with a higher percentage was achieved after the deep cryogenic heat treatment. These microstructural changes slightly improve the hardness of the samples but did not affect the wear behavior intensely. Furthermore, some nano-sized carbides were also produced in the structure, improving the hardness and wear resistance further.
