The technology of voice browsing is rapidly evolving these days. It is because the use of cellphones is increasing at a very high rate, as compared to connected PCs. Listening and speaking are the natural modes of communication and information gathering. As a result we are now heading towards a more voice based approach of browsing rather than operating on textual mode. This paper concentrates on this new technique, voice browsing, which unites speech recognition and speech synthesis that can be very fruitful in the coming years.

To secure data or information by a modified RSA cryptosystem based on ‘n’ prime. This is a new technique to provide maximum security for data over the network. It is involved encryption, decryption, and key generation. Prime number used in a modified RSA cryptosystem to provide security over the networks. In this technique we used ‘n’ prime number which is not easily breakable. ‘n’ prime numbers are not easily decompose. This technique provides more efficiency and reliability over the networks. In this paper we are used a modified RSA cryptosystem algorithm to handle ‘n’ prime numbers and provides security.
This abstract tells about a Wireless Technological Device which is popular for extremely Low Power, and Low Bit Rate Wireless PAN Technology called ZigBee. ZigBee is designed for wireless Automation and other lower data tasks, such as smart home automation and remote monitoring. ZigBee is a low-cost, low-power, wireless mesh networking standard. The low cost allows the technology to be widely deployed in wireless control and monitoring applications, the low power usage allows longer life with smaller batteries, and the mesh networking provides high reliability and larger range. Due to the low-cost and low-power usage this wireless technology is widely used in Home Automation, Smart Energy, Telecommunication Applications, Personal Home, Hospital Care. ZigBee enables new opportunities for wireless sensors and control networks. ZigBee is standard based, low cost, can be used globally, reliable and self healing, supports large number of nodes, easy to deploy, very long battery life and secure. 1. [1]
OLEDs are a great breakthrough in display technology .Also a new promising technology with high expected profitability on the display market. They show low driving voltages in combination with unrestricted viewing angles, high color-brilliance, light weight, small film-thicknesses and low production costs. Organic light-emitting devices (OLEDs) operate on the principle of converting electrical energy into light, a phenomenon known as electroluminescence. This paper focuses on structure of OLED, how it works, comparison with other display and applications.
Wi-Fi Localization using RSSI in Indoor Environment via a smartphone
Anupam Mahajan, MadhurChanana
The widespread availability of wireless networks (Wi-Fi) has created an increased interest in harnessing them for other purposes, such as localizing mobile devices. While outdoor positioning has been well received by the public, its indoor counterpart has been mostly limited to private use due to its higher costs and complexity for setting up the proper environment. In this paper, we use local Wi-Fi network to localize a mobile user in an indoor environment.Wi-Fi (or 802.11 networking) works on the basic principal that data packets are sent using radio waves. These radio waves can be received by any compatible receiver placed in a pc, mobile phone, tablet pc or any other circuit. The aim of this research paper is to explore the application of 802.11 networking for localizing the user or the receiver by using RSSI i.e. Received signal strength indication. Through Wi-Fi, one may be able to track objects or people in real time,whilst adapting to changes in both the environment, and the Wi-Fi network, in a reliable manner. Since Distance and RSSI share a inverse relationship. RSSI can be used to locate the general location of the user. An experiment is conducted in order to view the relationship b/w RSSI and Distance in an indoor environment using some basic domestic based equipment and an android phone.
