- Manoharan S,Loganayaki .C,Mohamed Rasith.M,Mohanraj. S ,Nowshin Sadikha.s.
Abstract
In these days energy resources is important source in today’s world. Conventional energy resources is the abundant for environmental pollution. Solar energy is one of the best power source in recent days. Solar energy gains rapidly in these days. Solar energy is used for the power shortage in India. Solar cells has been used increasingly in recent days to convert solar energy to electrical energy. The earth receives 84 terawatts of power and our world consumes about 12 terawatts of power per day we are trying to consumes more energy from the sun using solar panel. The tracker generates 16% to 24%more energy comparing to fixed tilt system. To increase the conversion from solar to electrical energy, the solar panels have to be positioned perpendicular to the sun. There are more technology to track the sun position. The single axis PV tracking system gives lower energy output during sun condition. So we are using dual axis PV tracking system to get more power and to increase the efficiency of power and the panel.We used thermoelectric generator to increase the efficiency of the solar panel.The Arduino based design methodology of an automatic tracking system is presented in this paper. LDR is used as sensing element.. Keyword: Light Dependent Resistor , Arduino UNO, Photo Voltaic cell, DC motor, Thermoelectric generator, Submersible pump. ×

The Segmentation of Lumen Boundaries at Intravascular Ultrasound Images
- C.priyanka, Dr.M.vanitha
Abstract
Intravascular Ultrasound Image (IVUS) is one of the medical imaging techniques based on the catheter. These techniques are very useful for studying heart diagnose and management of arterial atherosclerosis. It produces the vessel cross sectional images of blood vessels that provide the quantitative and qualitative assessment of the vascular wall information about the nature of atherosclerosis lesions as well as plaque size and shape. The identification of lumen, medium and adventitia limitations in IVUS images is compulsory for an efficient assessment of the atherosclerotic plaques. Throughout an IVUS assessment, a catheter with an ultrasound transducer is introduce in the deceased through a blood vessel and then pulled back to picture succession of container cross sections. This paper obtainable a one of the attractive and interactive methods is the Active Contour Model (ACM) with Local Image Fitting Energy Minimization (LIFEM) method which has been widely used in medical imaging technique as it always produces computationally efficient for sub-regions with continuous boundaries. In our approach maintains and deals with the boundary regularization property and sub-pixel accuracy. ..

Securing Message Using Steganography with Pixel Value Differencing Method
- Indah Puspasari Handayani, Pinan, Carudin, Maisaroh
Abstract
Steganography is a technique used in the process of sending secret messages. A cover file is used as a medium to hide the secret message. On the use of the image medium as a cover the message hiding process is done by replacing each pixel bit of the cover image with the secret message bits. LSB (Least Significant Bit) is a method that is often used by replacing the bits in the LSB cover position with secret message bits. Increasing message capacity and reducing the level of distortion in steganography have been carried out by developing PVD (Pixel Value Differencing) techniques. In the technique before the message bits are inserted into the LSB cover, first the cover image is divided into non-overlapping pixel blocks. Each block contains two pixels that are close together. Then, the difference in the values of the two pixels is used to determine the size of the message bits that can be inserted. A large pixel difference can accommodate many such messages otherwise a small difference can only be accommodated by a small message. Keyword: Steganography, Pixel Value Differencing ×

A Survey on video indexing and Retrieval
- N.Kalaivani , Dr.K.Mahesh .
Abstract
Video data dominate a lot of accumulation for those using multimedia system and employ like analogue depository, state-supported, educational activity, telecommunication and entertainment. Such employ are useful only when video recovery systems are economic sufficiency to recover video recording and other of the essence information from large databases as quick as possible. However, it is extremely ambitious for the existent entanglement scrutiny engines to search for video over the entanglement so novel methodological analysis are required that are surefooted of influence the video recording information accordant to the self-complacent. For multimedia excavation, harvester of transmission data are accumulation and ordered using proficiency like categorization and commentary of video recording. Most of the entanglement supported video retrieval systems work by indexing and searching videos based on texts associated with them but this technique does not execute well because the texts do not incorporate enough information of the video recording. Since video retrieval is not effectual using customary scene boundary perception technique, heritage based conceptualization is considered as one of the best applicatory solutions for better recovery attribute. This natural philosophy representation is a “live” Templet and already satisfactory the constituent of your paper [statute title, textual matter, heads, etc.] in its style sheet of paper.

FACTORS AFFECTING POWER SUPPLY IN NIGERIA AND THE WAY FORWARD
- Olajuyin E,Olubakinde Eniola,Adetunmbi Adewole Oyewale
Abstract
Power supply system which is very important and critical to national, social and economy development of nation and it is composed of three stages which are generation, transmission and distribution. Power is created and generated from a location with either hydro power plant, thermal power plant or other method etc, it is transmitted to the load centers through transmission lines (Underground cables or overhead lines) and finally dispersed through distributing lines to the various consumers for uses. The power system in Nigeria has suffered major setbacks and neglects from previous and past Administrations in Nigeria and this has compounded the problems of the sector. Some of the problems are destruction of gas pipe lines by vandals ,wrong and illegal connection of electricity, over billing of the consumers, mismanagement of funds, non execution of awarded power projects or non executing it to the standard specified and bribery and corruption to mention but a few. Some suggestions were made that can actually improve sustainability, security, reliability and availability of power system if properly implement. Also alternative sources of energies such as solar, biomass, wind and hydro should be embraced to generate clean and smokeless energy to replace the convection methods of generating electricity. It was suggested that the National Control Centre (NCC) in Oshogbo should be decentralized for a stable, regular and constant power supply.
