This paper examines the relevance of a fast approaching highly secure and fast data transmission technique using Li-Fi. It describes the upcoming technology Li-Fi and its applications as well as the developments made in it so far. It enlightens on the new era that will soon be used in almost all domains like health sector, school, bank and so on. An application framework design has been studied to analyze the role of Li-Fi in the process of communication.

Study on Data Transmission Using Li-Fi in Vehicle to Vehicle Anti-Collision System

Need of hiding information from intruders has been around since ancient times. Nowadays digital media is getting advanced like text, image, audio, video etc. To maintain the secrecy of information different methods of hiding have been evolved. One of them is Steganography which means hiding information under some other information without noticeable change in cover information. Video Steganography is the technique of hiding some covert message inside a video. In these paper work on improve data hiding capacity using video Steganography and use motion vector here for hiding data using LSB approach for hide text data. Using proposed system to improve images accuracy, embedding capacity. To enhance more security each bit of secret frames will be stored in covered frames. That are achieves good images quality when compared with existing method.

In the mechanical design constituent, numerical simulations method is mostly used for design instauration (or modification) and design optimisation. In the nowadays aim of work the first stage rotor leaf sword of a two-stage gas turbine has been analyzed for steady state thermal using ANSYS 16.2 an attempt has been investigated the effect of temperature on the turbine blade. A steady state thermal analysis has been carried out to investigate the focal point of the temperature flow rate which is been develops due to the thermal loading. An attempt is also made to suggest the best material for a turbine blade by comparing the results obtained for three different stuff such as Copper, Titanium and Nickel that has been considered for the analysis. The blade is modelled with SolidWorks 2015. The geometric model of the blade profile is generated with mathematically and extruded to get a solid model. In this work after finding the suitable materials, the analysis of different diam of hole also investigated. For different hole diameter, it has been pointed out that if the diameter of the hole is increased gradually with the constant number of holes, then the maximum temperature value and the total heat flux distribution decreases, then it grows again. Therefore, this present work the suitable diameter of hole also has been suggested for better performance in future.

The aim is to propose a system based on encryption of compressed video bit streams and hiding privacy information to protect videos during transmission using H.264/AVC. To maintain security and privacy video needs to be stored and processed in an encrypted format. Here, data hiding is done directly in the encrypted version of H.264/AVC which includes the following three parts i.e, H.264/AVC video encryption, data embedding and data extraction. choas encryption is used to encrypt/decrypt the secret data before/after data embedding/extraction. The simulated results shows that the methods used provide better performance interms of computation efficiency, high data security and video quality after decryption. The parameters such as mean square error, peak signal to noise ratio, correlation and structure similarity index are evaluated to measure its efficiency.

A new way of data transmission between two vehicles using light fidelity technology is proposed in this paper. A best way of avoiding accidents can be achieved by the communication between the vehicles. This system can be simplified by using LED bulbs for data transmission. The previously used data transmission technology can be overcome by the newly proposed LIFI technology. The major objective of this system is to achieve reliable communication between the vehicle using a transmitter and a receiver. The communication methods and the operations are presented in detail.

Muti-user resource allocation for cooperative OFDM systems is proposed for use in multi-user situations. The objective is to minimize the total two-stage transmission power for each user for a given transmission rate, formulate the optimization problem and proposes several algorithms for the allocation of various resources. The main aim is to allocate sub-channels for minimizing the total power of transmission.

Online object tracking plays major role in both Digital image processing and Medical image processing, where it is necessary to take an account of appearance change caused by intrinsic factors (e.g., pose variation and shape deformation) and extrinsic factors (e.g., varying illumination camera motion, and occlusions). Especially for the moving object, target is tracking by the sparse prototypes, an efficient technique which having the excellent updating capability by reducing the tracking drift, such as heavy occlusion and motion blur. The probable reduction of these drifts can be achieved by the conversion of low resolution image into high resolution image using the MAP estimation. Hence the sparse prototypes algorithm makes the moving object tracking in a wide range of applications in computer vision, such as surveillance, human computer interaction, and medical imaging. The initialized state (e.g., position and size) of the target in a frame and the goal of tracking is to estimate the states of the target in the subsequent frames.

Unfortunately, public transportation is not an easy mean to use and access by blind people in many countries. In case of buses, blind people have difficulty in recognizing and estimating the arrival of buses at the bus stations. In this paper a bus system using Radio Frequency Identification (RFID) is used. The blind people in the bus station are provided with the RFID reader which is recognized by the RFID tag in the bus. Then the blind people get the information about the arrival of the bus. The indication is made in the bus that the blind people is present in the station to the driver with the help of RF transmitter and RF receiver. So the bus stops at the particular station.
