Text classification is the task of assigning predefined categories to text documents. It is a common machine learning problem. Statistical text classification that makes use of machine learning methods to learn classification rules are particularly known to be successful in this regard. In this research project we are trying to re-invent the text classification problem with a sound methodology based...
In today's technological era, the cloud computing is the most popular because of its dynamic nature to provide the resources as per the user's need or request. The pay as per service pricing model add the strongest corner into the cloud computing. The services can be available and used anywhere, anytime makes the cloud computing more popular. But still the cloud computing has facing many issues. Task...
Cloud computing has become a popular buzzword and come out to be of great success in recent years with many advanced contributions. As cloud is storing an enormous amount of digital data engaged with third party services over the internet which raises new security concerns. Efforts are being made by researchers to make cloud secure and reliable computing environment. The technique used in this paper...
This paper present brain tumor detection and classification using discrete wavelet transform and Probabilistic neural network. The 2D Gabor wavelet (GW) analysis and Probabilistic neural network analysis has been generally used in face identification. Owing to the robustness of GW features against local distortions, variance of illumination and Probabilistic neural network give the proper results...
This paper deals with the energy saving at the data center using energy aware Virtual Machines (VMs) allocation and migration. The multi-objective based VMs allocation using Hybrid Genetic Cat Swarm Optimization (HGACSO) algorithm saves the energy consumption as well as also reduces resource wastage. Further consolidating VMs onto the minimal number of Physical Machines (PMs) using energy efficient...
HVDC transmission systems deals with bulk amount of power, therefore protection of these systems is highly important. This paper presents newly introduced voltage source converter with DC fault blocking capability, called hybrid cascaded multilevel converter. This converter has ability to prevent any uncontrolled fault current to flow from AC to DC side during DC faults, without the action of AC circuit...
Driven by the present day environmental concerns, distribution generation sources for electricity generation is increasing at a rapid pace. This makes a fundamental creation of microgrid as changing nature of distribution generation sources changes the quality of generated power. To avoid adverse effects of the unpredictable variations in RES many control concepts have been proposed in literature...
In this paper, a Flyback-Forward converter employing a non-cascading scheme is presented in discontinuous conduction mode. The converter is designed to enhance the duty ratio of over 50%. As a result, the flyback sub-converter acts in boost mode and generates stepped-up output voltage. Since the switch utilization is required to be as high as possible in a forward converter, in present case, this...
There is an increased need for scalable high performance computing systems as the amount of generated data grows. Traditional High Performance Computing (HPC) clusters built to handle big data processing have inherent weaknesses that can be overcome by migrating to a more flexible cloud computing environment. This article discusses high performance computing and the paradigm shift from traditional...
OFDM is a multicarrier modulation technique used in the 4G wireless communication which provides numerous advantages such as High speed data transmission, high spectral efficiency, robustness to multipath fading etc. Despite of all these enormous advantages one of the major drawbacks associated with the OFDM system is the high Peak to Average Power ratio value. In this paper, we have proposed various...
Underwater Communications (UWC) is a very demanding application in spite of issues like time varying multipath propagation, attenuation of the signal, underwater noise, and interference etc., Orthogonal Frequency Division Multiplexing (OFDM) is a suitable modulation technique for UWC as it has the ability to solve Inter symbol interference (ISI), Inter channel interference (ICI) and also multipath...
Cloud computing has gained much attention in recent years. In spite of several advantages, cloud computing involves a number of issues such as dynamic resource scaling and power consumption. These factors lead a cloud system to be inefficient and costly. Workload prediction is one of the factors by which the efficiency of a cloud can be improved and operational cost would be reduced. In this paper,...
Distributed scheduling is an important factor to enhance the network performance in IEEE 802.16 mesh network. The scheduling algorithm of control sub-frame was defined in IEEE 802.16 standard, but distributed scheduling of data sub-frame was not defined. In this paper, we propose a minimization of overhead using minislot allocation algorithm (MOMAA) for reducing the overhead of data sub-frame in IEEE...
