Design and Implementation of an Object-Oriented Operating System

-- Pinaki Chakraborty

Operating systems constitute an important class of software that forms the basis for proper functioning of all other software. This paper is a commentary on the design and implementation of a new object-oriented operating system. A microkernel-based architecture has been followed to develop the operating system. The operating system has a modular and stratified design with five distinct layers comprising system components and application programs. The design of this operating system extends the concept of the reincarnation server and introduces the concept of verbose server. All important entities in the operating system have been modeled as objects of suitably designed classes. The standard objectoriented programming techniques like abstraction, inheritance, delegation and polymorphism have been used to obtain an efficient implementation. The operating system supports a character user interface and a simple graphical user interface. A preliminary testing of the behavior of the operating system has been carried out and the results have been found to be satisfactory.

Innovative ICT Through Cloud Computing

--Harman Preet Singh, Arvind Bhisikar and Jitendra Singh

Cloud computing has emerged as a revolutionary paradigm through which organizations can optimize their Information and Communication Technology (ICT) investments. In cloud computing, ICT resource requirement can be adjusted easily and quickly in response to changes in demand. It is a scalable virtualized development platform that has the potential to provide pay-per-use services to customers over the Internet/network by deploying hardware and software resources. In this paper, the evolution of cloud computing is traced in 10 phases, starting from the development of calculating machine in 1623. An ICT model for cloud computing has been presented. In order to leverage the benefits of cloud computing successfully, a SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis of cloud computing is carried out. The paper also presents the details of cloud computing innovative applications in various organizations. Lastly, a hybrid cloud computing model for Small and Medium Enterprises (SMEs) operating in the developing countries is proposed. The results obtained for the hybrid cloud model demonstrated the feasibility of the model. It appears that the research base in cloud computing and hybrid model in particular is strong and possesses potential to help in the development of effective industrial applications. However, a proper need-benefit analysis should be carried out to hedge the restrictions and challenges faced by cloud computing.

Performance Analysis of VoIP and Voice over MPLS Networks

-- J Faritha Banu and V Ramachandran

The emerging demands of multimedia communications in Internet or intranet forces the Internet service providers to provide predictable or even guaranteed Quality of Service (QoS). The major critical issue for network researchers and service providers is how to provide high quality of communication services with limited bandwidth capacity. This study addresses various issues related to Voice over IP (VoIP) and voice over MPLS networks with IP QoS techniques, and provides a performance comparison. The simulation results reported identify the pros and cons of the two networks and find the best suitable service to provide guaranteed QoS for voice transmission.

A Neural Network Approach for Cardiac Arrhythmia Classification

--R Ganesh Kumar and Y S Kumaraswamy

Rapid or slow heartbeats cause irregular rhythms resulting in Cardiac Arrhythmia, which is assessed by electrocardiogram (ECG). There are various types of arrhythmia and its detection is relevant to heart disease diagnosis. Automatic arrhythmia ECG assessment is a wellresearched area. This paper investigates ECG classification using soft computing techniques to classify arrhythmia type through the use of RR interval. Discrete Cosine Transform (DCT) is used to extract features from the time series ECG data using the distance between RR waves. The extracted beat RR interval is used as a feature extracted in the frequency domain and classified using Multi-Layer Perceptron Neural Network (MLP –NN), and proposed Feed Forward Neural Network (FNN) experiments were conducted through the MIT-BIH arrhythmia database.

Automated Teller Machines (ATMs): The Changing Face of Banking in India

Bank Management
Information and communication technology has changed the way in which banks provide services to its customers. These days the customers are able to perform their routine banking transactions without even entering the bank premises. ATM is one such development in recent years, which provides remote banking services all over the world, including India. This paper analyzes the development of this self-service banking in India based on the secondary data.

The Information and Communication Technology (ICT) is playing a very important role in the progress and advancement in almost all walks of life. The deregulated environment has provided an opportunity to restructure the means and methods of delivery of services in many areas, including the banking sector. The ICT has been a focused issue in the past two decades in Indian banking. In fact, ICTs are enabling the banks to change the way in which they are functioning. Improved customer service has become very important for the very survival and growth of banking sector in the reforms era. The technological advancements, deregulations, and intense competition due to the entry of private sector and foreign banks have altered the face of banking from one of mere intermediation to one of provider of quick, efficient and customer-friendly services. With the introduction and adoption of ICT in the banking sector, the customers are fast moving away from the traditional branch banking system to the convenient and comfort of virtual banking. The most important virtual banking services are phone banking, mobile banking, Internet banking and ATM banking. These electronic channels have enhanced the delivery of banking services accurately and efficiently to the customers. The ATMs are an important part of a bank’s alternative channel to reach the customers, to showcase products and services and to create brand awareness. This is reflected in the increase in the number of ATMs all over the world. ATM is one of the most widely used remote banking services all over the world, including India. This paper analyzes the growth of ATMs of different bank groups in India.
International Scenario

If ATMs are largely available over geographically dispersed areas, the benefit from using an ATM will increase as customers will be able to access their bank accounts from any geographic location. This would imply that the value of an ATM network increases with the number of available ATM locations, and the value of a bank network to a customer will be determined in part by the final network size of the banking system. The statistical information on the growth of branches and ATM network in select countries.

Indian Scenario

The financial services industry in India has witnessed a phenomenal growth, diversification and specialization since the initiation of financial sector reforms in 1991. Greater customer orientation is the only way to retain customer loyalty and withstand competition in the liberalized world. In a market-driven strategy of development, customer preference is of paramount importance in any economy. Gone are the days when customers used to come to the doorsteps of banks. Now the banks are required to chase the customers; only those banks which are customercentric and extremely focused on the needs of their clients can succeed in their business today.
