The purpose of clustering is grouping similar data together in a group, so were most similar to each other in a cluster and the difference with most other instances in the cluster are. In this paper we focus on clustering partition k-means, due to ease of implementation and high-speed performance of large data sets, After 30 year it is still very popular among the developed clustering algorithm and then for improvement problem of placing of k-means algorithm in local optimal, we pose extended PSO algorithm, that its name is ECPSO. Our new algorithm is able to be cause of exit from local optimal and with high percent produce the problem’s optima...

What strategies should be deployed to overcome the inhibitors of cloud computing? These are but few questions this paper aims to investigate. Studies have shown that, cloud computing has become a strategic direction for many government agencies and is already being deployed in many critical areas of the government's cyber infrastructure. The benefits and the challenges of cloud adoption have heightened interest of academic research in recent times. We are however uncertain, per literature factors tha...

Amin Rostami1 and Mohammad Hossin Mottar2 1Department of Computer Engineering, Ferdows Branch, Islamic Azad University, Ferdows , Iran. 2Department of Computer Engineering, Mashhad Branch, Islamic Azad  ABSTRACT  Wireless sensor networks (WSN) is composed of a large number of small nodes with limited functionality. The most important issue in this type of networks is energy constraints. In this area several researches have been done from which clustering is one of the most effective solutions. The goal of clustering is to divide network into sections each of which has a cluster head (CH). The task of cluster heads collection, data aggregation and transmission to the base station is undertaken. In this paper, we introduce a new approach for clustering sensor networks based on Particle Swarm Optimization (PSO) algorithm using the optimal fitness function, which aims to extend network lifetime. The parameters used in this algorithm are residual energy density, the dista...

Hasan Omar Al-Sakran Management Information Systems Department, King Saud University, Riyadh, Saudi Arabia ABSTRACT Due to diversity, heterogeneity and complexity of the existing healthcare structure, providing suitable healthcare services is a complicated process. This work describes the conceptual design of an e-healthcare system, which implements integration strategies and suitable technologies that will handle the interoperability problem among its essential components. The proposed solution combines intelligent agent technology and case based reasoning for highly distributed applications in healthcare environment. Intelligent agents play a critical role in providing correct information for diagnostic, treatment, etc. They work on behalf of human agents taking care of routine tasks, thus increasing speed and reliability of the information exchanges. CBR is used to generate advices to a certain e-healthcare problems by analyzing solutions given to previously solved proble...

ABSTRACT There are three stages of Enterprise Resource planning System (ERP) Implementation; which are preimplementation, mid- implementation and post-implementation. In pre-implementation stage the pervious researchers found that it fail in Organizational and Technological factors. Therefore, this research studies the Technological Factors availability and the Organizational Factor readiness at Greater Amman Municipality (GAM) Case study. The statistical results showed that there are availability of the Organizational factor (Organizational Objectives and Services, Organization culture, and Business process) for success of ERP system, and indicate the technological infrastructure is available og GAM. KEYWORDS Enterprise Resource Planning, Critical Success Factors , ERP Implementation.

Eman Al Helal and Hala Mokhtar College of Computer and Information Sciences, King Saud University, KSA, Riyadh  ABSTRACT  In the past ten years, the role of citizens to achieve smart city vision is realized and the people-centric Smart City model has been stressed. In this paper, we propose “Riyadh Wiki Information and Complaining System” for citizen engagement in Riyadh city in Saudi Arabia. The system follows the crowd sourcing approach by allowing citizens to act as sources of data to support the government and to improve their city. It also follows the co-design approach by being an open source platform that allows citizens to cooperate to build the system and add new services. The system aims at enhancing citizens’ life and solving governmental issues like transparency, trust, decision-making, and accountability in a cheap way. It is developed as a web-based wiki system, so it can be used easily by the non-skilled citizens while allowing skilled citizens to add ...

Julius Raphael Athuman Mhina , Md Gapar Md Johar Management & Science University, Faculty of Information Sciences & Engineering, Shah Alam, Selangor, Malaysia  ABSTRACT  The aim of this paper was to present factors which influence work-related adoption of social media among government employees. The study adapted the Unified Theory of Acceptance and Use of Technology (UTAUT) and integrated it with three constructs namely Hedonic Motivation (HM), Perceived Personal Image (PI) and Attitude (AT). The sample of study consisted of 600 usable responses collected using survey questionnaire from employees based in Tanzania Ministries, Departments and Agencies (MDAs) employing convenience sampling technique. The data was analyzed using Structural Equation Modelling. The results showed that, PI and HM influence attitude (AT), while PI, Social Influence (SI) and AT influence Behavior Intention (BI). Moreover, SI, PI, AT and BI showed significant effect on actual Use Beh...
