Currently speaking, lack of efficient Information Technology infrastructure makes the development of E-Commerce a lot more complicated. This relates to the fact that information required for supervisory-regulatory entities is not being updated. Insurance industry is the most important part of E-Commerce and, hence, shifting all transactions to the electronic environment in order to improve its penetration rate is inevitable. By advent of electronic insurance and its influence in all industrial sectors, rapid development of it can be expected. This paper introduces the life cycle of the insurance industry in which the development process and the role of information technology in each section of this cycle has been studied; In the form of a three-dimensional model, the effect of information technology on the key elements of the industry is analyzed, and in order to reduce costs and increase efficiency in managing large-scale insurance industry, a new approach based on virtualization is proposed in which the new arrangement of information technology infrastructure is described. Finally, by evaluating the effect of virtualization on the development and maintenance of IT infrastructure, efficiency of proposed method is displayed. Read More Read Less

Cognitive developmental theories attempt to explain cognitive activities that contribute to students’ intellectual development and their capacity to learn and solve problems. Cognitive developmental research has had a great impact on the constructivism movement in education and educational technology. In order to appreciate how cognitive developmental theories have contributed to the design, process and development of constructive e-learning environments, the author will first present Piaget’s cognitive theory and derive an inquiry-training model from it that will support a constructivist approach to teaching and learning. Second, an example developed by the author and his graduate students will be presented that uses the Web as an appropriate instructional delivery medium to apply Piaget’s cognitive theory to create e-learning environments. The result is a collection of simple, uniform, and effective inquiry-training math web sites for elementary and middle school students. The information presented can be applied to other subject areas as well. Read More Read Less

Abstract Radix Search is a searching algorithm for finding a particular value in a list by checking each one of its elements. It searches an item by processing individual digits and finally it undergoes a linear method also to make sure the presence or absence of the item in the list. The time complexity of Radix search is 2 (n+1) th... Radix Search is a searching algorithm for finding a particular value in a list by checking each one of its elements. It searches an item by processing individual digits and finally it undergoes a linear method also to make sure the presence or absence of the item in the list. The time complexity of Radix search is 2 (n+1) th of Linear Search where ‘n’ is the maximum number of digits of a number in the list. Read More Read Less

Abstract In this paper, performance of a dual particle-number Rao-Blackwellized particle filter (RBPF) for speech enhancement is evaluated. Speech is corrupted by additive white, colored and real industrial noises that degrade its intelligibility. The performance indexes are: Quality of the processed speech scored by PESQ and computation time. The simulation results indicate that the RBPF methods outperform some well known Kalman... In this paper, performance of a dual particle-number Rao-Blackwellized particle filter (RBPF) for speech enhancement is evaluated. Speech is corrupted by additive white, colored and real industrial noises that degrade its intelligibility. The performance indexes are: Quality of the processed speech scored by PESQ and computation time. The simulation results indicate that the RBPF methods outperform some well known Kalman based algorithms in the cost of more computation time. The weakness, then, is overcome by the dual particle-number RBPF that saves the quality of the processed speech while reduces remarkably the computation time. Read More Read Less
