Suspension containing 10wt%, 30wt%, and 50wt% YSZ were fabricated using the spin coating technique on silica keeping all other parameters constant such as the coating parameters and sintering temperature.The surface morphology and thickness of the films were investigated using scanning electron microscopy (SEM). Results showed porous YSZ films which become less porous as the concentration of YSZ increases. The thickness of the films was also affected by the YSZ concentration. As the concentration increases, the thickness of the films also increases. The crystal structure of the favricated films was also determined using X-Ray Diffraction (XRD) and Raman Spectroscopy. Both Techniques revealed a cubic fluorite structure independent of the concentration of YSZ.

Today's internet has the most of limitations which is important to remove. In future internet we used IPv6 protocol instead of IPv4 which have the larger address. It is important because the no. of users and system quantity are larger. In this paper we prepare the scope of future internet which will provide higher data transfer rates and high speed accessing to user. By designing new architecture and using new protocol version we can fastly access live TV and Multimedia data streaming on our computer. We can also enjoy the live video conferences because internet speed will be faster and powerful. Here we also describe the term dynamic caching which is important for accessing same data streaming on multiple places on the same time.

In order to reduce the image blur caused by the degradation, the remote sensing images were restored to give prominence to the characteristic objects in the images.the images were restored. IMAGE restoration is an important issue in high-level image processing..The purpose of image restoration is to estimate the original image from the degraded data. It is widely used in various fields of applications, such as medical imaging, astronomical imaging, remote sensing, microscopy imaging, photography deblurring, and forensic science, etc. Restoration is beneficial to interpreting and analyzing the remote sensing images. After restoration, the blur phenomenon of the images is reduced. The characters are highlighted, and the visual effect of the images is clearer. In this paper different image restoration techniques like Richardson-Lucy algorithm, Wiener filter, Neural Network,Blind Deconvolution.

The provision of fresh water is becoming an increasingly important issue in many areas of the world. Among the non-conventional methods to desalinate brackish water or seawater, is solar distillation. The solar still is the most economical way to accomplish this objective. Tamilnadu lies in the high solar radiation band and the vast solar potential can be utilized to convert saline water to potable water. Solar distillation has low yield, but safe and pure supplies of water in remote areas. The attempts are made to increase the productivity of solar still by using different absorbing materials, depths of water, heat storage medium, nanofluids and also by providing low pressure inside the still basin. Heat transfer enhancement in solar still is one of the key issues of energy saving and compact designs. The use of additives is a technique applied to enhance the heat transfer performance of water in the still basin. Recently, as an innovative material, nanosized particles have been used in suspension in conventional solar still water. The fluids with nanosized solid particles suspended in them are called "nanofluids." The suspended metallic or nonmetallic nanoparticles change the transport properties, heat transfer characteristics and evaporative properties of the base fluid. Nanofluids are expected to exhibit superior evaporation rate compared with conventional water. The aim of this paper is to analyze and compare the enhanced performance in a vacuum single basin solar still using nanofluids with the conventional water. They greatly improve the rate of evaporation and hence the rate of condensation on the cooler surface.

By ensuring that the system operates at a minimum energy for each quality point, the system can achieve both flexibility and energy efficiency, allowing the end-user to maximize system lifetime. Simulation results show that the proposed adaptive clustering protocol effectively produces optimal energy consumption for the wireless sensor networks, and resulting in an extension of life time for the network. The preparation phase is performed only once before the set-up phase of the first round. The processes of following set-up and steady-state phases in every round are the same as LEACH. Simulations show that LEACH can achieve as much as a factor of 8 reductions in energy dissipation compared with conventional routing protocols. In addition, LEACH is able to distribute energy dissipation evenly throughout the sensors, doubling the useful system lifetime for the networks we simulated

Disaster reduction is both an issue for consideration in sustainable development agenda and a cross cutting issue relating to social, economic, environmental and humanitarian sectors. These important features have to analyze and there is a need to study. Though, in recent years the Open GIS technology standards have been developed by several agencies, which provide the basis for utilization of geographic information services, also gives an opportunity for data interoperability, data integration and data sharing between different emergency management agencies, However finding suitable services and visualization of geospatial information for decision makers is still a crucial task. Objective of this paper is to assess the state of art literature review in different methodologies of utilizing geospatial technology in managing both natural and manmade disasters dedicated by different authors and also to find new direction in this important area.

We have therefore designed a new architecture called embedded concurrent computing (ECC), which is implementing on FPGA chip using VHDL. The design methodology is expected to allow scalable embedded multiprocessors for system expansion. In recent decades, two forces have driven the increase of the processor performance: Advances in very large-scale integration (VLSI) technology and Micro architectural enhancements. Therefore, we aim to design the full architecture of an embedded processor for realistic to perform arithmetic, logical, shifting and branching operations. We will be synthesize and evaluated the embedded system based on Xilinx environment. Processor performance is going to be improving through clock speed increases and the clock speed increases and the exploitation of instruction- level parallelism.We will be designing embedded multiprocessor based on Xilinx environment. These data have been gathered by synthesis. Implementation was achieved by the provision of low complexities in terms of FPGA resource usage and frequency. In addition, the design methodology allows scalable embedded multiprocessors for system expansion.

The formula is developed by considering a continuous section of the number line between P and P2. The length of this section is repeatedly divided by primes below P to obtain the number of primes in the region. The process is similar to the Sieve of Eratosthenes. However, instead of eliminating the multiples of primes below P, it eliminates the number of multiples of these primes. This reduces it to a simplifiable algebraic expression that can easily be implemented using programs.

The delivery of the proper quality of audio signals to the audience in the entertainment, public ... more The delivery of the proper quality of audio signals to the audience in the entertainment, public and other environments is of great, and sometimes critical, importance. This always requires that the audio signals be of the correct intensity to the hearing of the audience, especially if the signals come from different sources. This work presents a system which automatically fades out the main stream signal when signals from other sources are received. By arranging the circuit such that the signal from the other sources continuously drives a pair of bipolar junction transistors towards heavier saturation, the mainstream signal was attenuated by as much as 3 dB

Intrusion Detection System (I.D.S) is a component of the security infrastructure designed to detect violations of security policy. Most of the intrusions can be localized either by considering of models "pattern" of user activities (non-behavioral approach) or by considering the audit log (behavioral approach). False positives and false negatives are considered as the major disadvantages of these approaches. We consider that good I.D.S should respond to the characteristics of intelligent agents such as autonomy, distribution and communication.

Despite their outstanding characteristics, ceramic materials are not used in many cases due to high cost of machining. A major drawback to engineering applications of ceramic is due to their brittleness and fracture tough-ness, which makes them difficult and costly to machine.

This paper presents a novel approach to determine reference compensation currents of the three-phase shunt active power filter (APF) under distorted and/or imbalanced source voltages in steady state. The proposed approach is compared with three reviewed shunt APF reference compensation strategies. Results obtained by simulations with Matlab and Simulink show that the proposed approach is more effective than the reviewed approaches on compensating reactive power and harmonic/neutral currents of the load, even if the source voltages are severely distorted and imbalanced. In addition, the proposed approach yields a simpler design of the shunt APF controller.

The results showed that there were three species of bee-eaters belonging to family (Meropidae) in the considered location, European bee-eater (Merops apiaster Linnaeus, 1758); Olive bee-eater (Merops superciliosus Linnaeus, 1766) and Green bee-eater (Meropa orientalis Latham, 1802). The three species recorded were migratory and they were found in the apiaries during two seasons (spring and autumn). In spring, they were first appearance in the bird-trapping nets on March 28, 2009, and on April 02, 2010, meanwhile, they were last time in the bird-trapping nets on May 01, 2009 and April 20, 2010. In autumn season, they appeared in the considered apiaries on September 23, 2009 and October 11, 2010, meanwhile, the last time they were appeared in the apiaries on November 04, 2009 and November 01, 2010. Results suggest that the direction of bird-trapping nets significantly affected the number of trapped bee-eaters, the placing of bird-trapping nets in the east side of the apiary and above the apiary led to a significant trapping of more of bee-eaters than when placed in west, north and south directions. In addition, no significant difference was found in trapped bee-eaters during the two inspection periods, in the morning (9 am) and in the evening (5 pm).

It is really difficult to realize the problems and sorrows of a physically disabled/crippled person who is partially or fully dependent on others or confining himself in a wheel chair with limited mobility. This paper provides idea of currently available three-wheelers for disabled people and proposes a new improved design of a solar powered three-wheeler suitable for countries like Bangladesh which is an under developed country with huge disabled/crippled people from war, accidents and diseases. This three-wheeler is operated by solar power and suitable for outdoor use. Solar power option enables the disabled people to use it at any place, even in remote areas where there is no electricity. A general survey had been conducted on disabled people using wheel chairs and manual three-wheelers and the opinions of the experts working with the disabled people are also taken in to consideration to identify the needs and requirement for designing the solar three-wheeler. The proposed solar three-wheeler is meant to match and exceed the conventional three-wheeler's facilities with a more intelligent and efficient design. A solar panel to produce solar electricity, a battery system for preserving electric power, an efficient motor, cushion seat, all terrain tires are used for this solar three-wheeler. Due consideration and attention is given to better maneuverability, effective use of solar energy, biomechanics and comforts, increased suspensions, all terrain traffic ability, ease of use etc. while designing this solar three-wheeler for physically disabled people of the country.

This report examines the design, development and testing of an experimental model Bubbling fluidized bed combustor. Three unique features to enhance performance of this system were suggested and comprehensively discussed; inert bed's temperature regulating unit, an integrated unit that enable Fluidizing air pre-heating as well as Biomass feeding pipe's cooling and segmentations of the Combustor body into modules /partitioning of these modules into lower and upper section. The results of the test run with Palm kernel shell and Coconut shell show that the system performance is enhanced and that the temperature is well regulated as observed in the thermal distribution. It is therefore proposed that the present Bubbling Fluidized bed combustor could be beneficial to development of commercial sizes for power generation in Nigeria and Africa sub region.
