A New Model for Automatic Runtime Error Detection in Java Programs
Mortaza Mokhtari Nazarlou, Javad badali and Amir Omidi

In order to detect runtime errors using program monitoring, specifications are necessary. This paper presents a novel model that describes hierarchical structure of program runtime behavior. The model is composed of elements with granularities from activity, object to action. By observing program behavior as it runs, we construct hierarchical view of program executions and extract behavioral models automatically. After that we propose an automatic technique for runtime error detection for java programs with a preliminary experiment.

Abbas Karimi, Javad Sofiyabadi, Pourandokht Niroumand, Mahboubeh Ranjbar and Mohammad Karimi

Foreign Direct investment (FDI) and other investment flows are core matters in development that needs a suitable environment for political, economical, technological and cultural cooperation among countries. In this paper, first, literatures on FDI, special economic zone (SEZ) and ease of doing business, 2013 in Iran will be reviewed to specify the main factors affecting on FDI. This study, then, tries to assess and rank the 3 main determinants and 9 factors to attract FDI in Iran especially Persian Gulf area, South Pars SEZ by using an integrated approach consisting of fuzzy DEMATEL and COPRAS. Findings show that among the determinants including; economical conditions in host countries, host country policies, and investment strategies of multinational enterprises, the last one is a crucial determinant to attract FDI in SEZs. The paper also segments the 9 factors in 2 meaningful groups and found that priorities of these factors are not the same. So policy makers, SEZ top managers and officials would be better to pay attention to and focus on FDI policies, Trade & industry, and Private sector factors as the 3 most important ones. The results can be useful for the region’s policymakers and managers in order to compile suitable development strategies and policies, to improve the business environment for ease of doing business and to attract more investors.

Meledje Djedjess E. J-C, Ziao Nahossé, Boa David, Yapo Aboua Jacques and Kotchi Kouadio Pierre

This work relates to mineralization of soap factory wastewater by H202/Fe(II) system. The objective of study is to seek the optimal operating conditions to reduce the organic load defined by COD (Chemical of Oxygen Demand), based on chemical kinetics. Experimental work was realized at temperature of raw water by applying initial hydrogen peroxide amounts (3.47x10-3 to 1.74x10-2 mol.L-1 of H2O2) and a molar ratio H2O2/Fe2+ equal to 2. The abatement of COD are approximately 6 to 17% with 3.47x10-3 mol.L-1 H2O2, against 42 to 50% with 1.74x10-2 mol.L-1 H2O2. H2O2/Fe(II) system seems more effective when the pH value is equal to 3 for mineralization of organic matter. The removal of DCO is supposed to follow a second order law.

eGovernance: Government of the People, By the People and For the People
Laxmidhar Sethy, Binod Kumar Pattanayak and Gopa Krushna Pradhan

Government and governance are basically mechanisms for collective action. When the collective action is necessarily backed by policing power it is called ‘government’: in this case the totality of activities taking place is akin to rowing a boat. When the collective action is not necessarily backed by policing power it is called ‘governance’: in this instance the totality of activities taking place is akin to steering a boat. The two taken together is a broadened form of government called network version of government of networked government, in short. The western model of governance, that is, ‘government of the people, by the people and for the people’ belongs to the latter category. When we define Digital Government (as the Mexicana government has done) as ‘the continuous innovation in the delivery of services, citizen participation, and governance through the transformation of external and internal relationship by the use of information and communications technology (ICT)’, we are implicitly assuming a network type of government. In this paper we highlight the problems that may arise when we apply it to developing countries.

Preventing Session Hijacking and Phishing through Web Services
Emilin Shyni.C and S. Swamynathan

Providing secure services in commercial sites is a challenging task due to security reasons in web applications. Session hijacking is the exploitation of a valid computer session or session key to gain unauthorized access to information. Phishing is one of the major web application attacks. In order to prevent session hijacking, Session Hijacking Attack Prevention System, a web service based detection and prevention mechanism is used. It fetches and validates user request and response. To implement this mechanism every request and response will be checked for session hijacking. Session fixation will be prevented by validating session ID, IP address and hostname for every user request and invalidates any mismatched session after login. URL is generated once using Universally Unique Identifier and Time Stamp to provide security for short time living services, and handler is used as a gateway for every request. Using that session information we can detect whether the site is a phishing site or not.

Potential Bagasse Ash Utilization in the Manufacture of Hollow Concrete Block – An Experimental Study
Radhika Kowsik and S. Jayanthi

Disposal of Sugarcane bagasse ash poses serious of pollution problems in developing countries. In India every year about 300 million tons of sugarcane is produced. As a result 10 million tons of Bagasse ash is generated which in turn causes bioenvironmental problems and environmental pollutants. Reuse of sugarcane bagasse ash as an alternate binder for the replacement of cement in concrete is investigated worldwide for the recent past years. Efforts were made to study the pozzolanic activity of sugar cane bagasse ash to improve the mechanical properties of concrete. With this vision in the present study silica fume was added as admixture to the ungrounded bagasse ash based concrete and its mechanical properties on hollow concrete blocks are reported. The test result indicates that addition of silica fume by 10% as admixture substantially increases the mechanical properties on ungrounded bagasse ash based concrete at all replacement levels.
Keywords: Hollow concrete block, Bagasse ash, Silica fume, compressive strength, density, water absorption.

DTC Controller Design for IM with Wavelet Noise Reduction
Khalaf Salloum Gaeid

The algorithm of the direct torque control (DTC) involves a decoupling of both torque and flux through a two control loops. In this algorithm, the inverter switching ability is completely used as a result improves the overall system performance. Stator flux and torque estimation based on voltage model and low pass filter is used to overcome the saturation and DC drift. New method of DTC using wavelet improves the induction motor operation, such as minimizing the noise in the inner and outer operation closed loop system. The simulation results prove that the proposed control algorithm is efficient and robust in both transient and steady state regions.

Mohammad Reza Nikbakht, Seyed Ali Mahdian and Alireza Ramrouz

Though manufacturing institutions all over the world increasingly move towards using lean management systems, studies indicate that many lean institutions still use this traditional system, despite preventing the standards costing system from executing the lean one. In this article, we study how lean manufacturers use standard costing in comparison with lean theory. In addition, we offer a viewpoint that why lean manufacturers still continuously use standard costing and variances analysis. In this regard we present six arguments.

International Financial Reporting Standards (IFRS), Reality or Exaggeration
Ahmadali Yazdanpanah, Seyed Ali Mahdian, Alireza Ramrouz and Sepideh Kavand

Recently, over 100 countries have begun to execute the International Financial Reporting Standards (IFRSs) or are about to conduct them. Undoubtedly, carrying out an international modification to a prevalent branch like accounting which affects cultural, political, economical, and social aspects of human life would bring about an abundance of consequences, including economical ones. Many researches have been conducted on the economical consequences of the standards. In most cases, the positive results of executing the standards have been supported. However, there are some unclear points. Hence, the current project revises the conducted researches and discusses the vagueness.

An Analysis of Load Balancing in a Cloud Computing Environment
Ajith Singh. N and M. Hemalatha

Load balancing is implemented in the computing environment to utilize the resources efficiently and effectively, sharing of resources is common in computing world but to utilize in an efficient way is done by the load balancer. Cloud Computing is the most recent topic in IT industry due to its flexibility in using the computing system. Cloud computing provides everything as a service. The increase in web traffic and different application in the web world is increasing day by day where millions of data are created every second. Load balancing has become a very popular research field due to need of balancing the load on this heavy traffic. Cloud computing as new computing technologies use virtual machine instead of physical machine to host, store and network the different nodes for their specific purpose. The load is done on CPU load, memory capacity, and network. Load Balancing is done in such a way that the entire loads are distributed among various nodes in a distributive system. Failure of any node in the network will lead to unavailability of web resource in the web world. Load balancing should be able to provide scalability and availability. Therefore, in this paper we study the different Load Balancing algorithm which is already available for such kind of distributed environments.

M.Yuvaraju and N.Devarajan

In this paper an Improved Water Swirl Algorithm (IWSA) approach for modeling a lower order Linear Time Invariant Discrete System (LTIDS) has been dealt. A linear transformation z=p+1 is used to analyze the problem in continuous domain. A simple average scheme has been suggested for obtaining the initial lower order model in p-domain. An Improved Water Swirl Algorithm is used to obtain a better lower approximant that reflects the characteristics of the given original higher order system in p-domain. Cumulative error index computed from the integral square error is used as an objective function for selecting the best lower order model. Applying reverse transformation p=z-1, the final transfer function of the lower order model is declared. The simulation results obtained shows the application of Improved Water Swirl Algorithm for modeling of LTIDS produces a better lower order system compared to other techniques available.
Keywords: Higher order system, Transfer function, Lower order system - Linear transformation – Average scheme – Improved Water Swirl Algorithm.
