Nilamadhab Mishra and Prof. S. N. Mishra

In the last decade, virtualization technologies have become very popular. Virtualization enables a user to run multiple operating systems on the same computer concurrently, while providing a degree of isolation between OS instances. Even though virtualization is mostly used on servers, its popularity on desktop also rises, where it is mostly used in cross-platform development and execution of software available to other platforms. Since both of these use cases are performance intensive, the goal of this paper is to evaluate the performance of a couple of the most popular desktop virtualization tools on the market, i.e., VMware Player and Oracle Virtual Box. Benchmarks used in this paper evaluate the performance of the tools in both CPU intensive and GPU intensive applications, with special emphasis placed on the performance of multi-threaded applications.

Audio Codecs in Cloud Computing

Suresh Kumar Sahu

A codec is a device of computer program capable of encoding or decoding a digital data stream of signal. Now a days we are dealing with words like mp3, mp4, aac, 3gpp etc. Let us solve the mystery behind the latest technology in audio and video processing techniques and its use in Cloud computing. The perceptual audio range of a human being is 20 Hz to 20 kHz. That means the human ear can sense the sounds in this range of frequency. If we want to store the audio outcome from a source we must store the human ear perceptual range of frequency components. Generally the audio output from a source is in analog form. Before the development of digital data storage, the audio signals stored in analog form on devices like magnetic tapes and gramophone etc. the analog signals again converted to sound when we need them. In analog format the data storage is costly, bulky, power consuming and of less quality. These disadvantages can be overcome by digital signal processing techniques. Also we can use the Cloud computing for better usage of the digital techniques.

Implementing Security in Virtual Machines in Cloud during Query Phasing

Mohanty Anita and Mishra Sambit Kumar

Now-a –days virtual machines are creating interests among scientists. The main advantage with virtual machines are that even if multiple operating systems exist in a computer still they are isolated with each other. So in cloud when a query is processed data are shared and in a virtual machine number of operating systems are working. So data security is a major issue over there. Though encryption is provided but now the concern is who should manage and control the encryption key. A cloud service provider can decrypt the data without the knowledge of the data owner which is unethical. In this paper we propose a scheme to provide better security to data in cloud during query phasing.

Amit Chandra Kesh, Gouranga Charan Jena & Siddharth Swarup Rautaray

Odia is the sixth Indian language to be designated a classical language in India. Also, Odia is a predominant language of Odisha, where native speakers make up 80% of the population. The oldest evidence for Odia dates back to the 3rd century BCE. Even if, Odia language is spoken & used by over 40 million people and having such an important Indian language, as of now there is no significant translation tool available for Odia language. On the other hand although 95% Schools use Odia as the main medium for study in Odisha, still there are rarely any Digital Education Materials available for Odia Language. Today, with wealth of Educational information available in English and other languages available through social networks and World Wide Web, there is an undeniable need to formulate efficient techniques to process such data to make the digital information available in Odia Language. This paper presents a method for forming inter-lingual i.e. word-for-word or phrase-for-phrase mappings between languages for Odia Translation
