A device for the detection of polymers is under the development. The use of ultrasonic waves for understanding the aquatic environment is undertaken in this work. The material presented explains how the waves behave for different samples (size, shape, composition) of polymers and the observation is the signature of the species under study.
The requirement of higher data throughput in wireless communication systems is ever increasing. Exponential growth in mobile data traffic has led researchers to innovative ideas to cater for these new requirements. At present 4th generation wireless systems are being deployed. In near future, data throughput requirements will even surpass this new technology. Research on 5G has already started where,...
Cloud computing technology is known for its potential advantages which include cost reduction, enhanced flexibility, improved stability and the provision of a proven delivery platform for delivering IT services to its end users. In spite of the numerous benefits, cloud computing does attract security threats and therefore has vulnerabilities. Understanding and mitigating such threats and vulnerabilities...
Cloud computing nowadays is adopted by many organizations around the world because of its potential benefits such as cost reduction, high availability and elastic scaling. In spite of all the claimed benefits and to deal with any potential risk and vulnerability of cloud computing, risk management is becoming a critical domain that requires a fundamental review in the business strategies and can be...
The immense improvement in information and communications technologies (ICT) has motivated service providers to offer services through electronic channels. Governments also realize the widespread, cost-effective and strategic roles that ICT plays in order to serve citizens and other businesses. With the development of a greater number and variety of e-services, citizens have higher expectations and...
New technologies are affecting many different aspects of our lives. Social media is one of these, and has revolutionized communication between governments and their citizens. Both governments and citizens are benefitting through this social interaction, which has resulted in more effective services being offered to citizens.
Most of the organizations not only compete in their field of expertise, but they also compete to be the leaders and the initiators of using modern applications and advanced technologies. Therefore, as the amount of data to be stored is inevitably increasing, the demand for faster data retrieval and sharing is getting higher and the level of security is becoming more critical. Most organizations enter...
This paper presents the design of an implemented prototype of a multi-rate Continuous Phase Frequency Shift Keying (CPFSK) transmitter. In case of a fixed rate CPFSK transmitter, the input symbol rate remains constant, thus the pulse shaping filter and frequency deviation are also fixed to a certain bandwidth. Contrary to this, for a multirate CPFSK design, the input symbol rate may vary and the pulse...
For many smaller and larger entities over the last couple of decades, information systems and technologies have become an integral part of their operations and played a major role in drastically changing and often improving their business processes. As computers become more and more integrated into our business organizations, we end up leaving and storing confidential, vital business and sensitive...
Cognitive radio is a popular research topic that has attracted considerable interest in the recent past. This paper aims at carrying out a literature review on the subject thus giving an overview of the concept with special emphasis on more popular research areas. The prime consideration for the selection of the papers has been their citations in the subsequent research work. The review has been followed...
This research paper compares the result of Object based and Pixel based classification techniques for glacier change detection on Landsat Thematic mapper (TM) and Enhanced Thematic Mapper (ETM+) imageries. The objective of this study is to see which classification method performs better for change detection in mountainous regions. Northern face of Himalayan region, The study area is undergoing climate...
In early 20th century when technology evolve, the performance of systems suffered from the problems of complexity, increasing cost of maintenance and software of hardware failure caused by unpredictable behavior and poor manageability. This fostered researchers to discover new design and techniques that enable the systems to operate autonomously. In 2001, IBM introduces self-managing capabilities...
