Role of Coating in Improving High Temperature Oxidation of Steel |
||||||||||||
Oxidation is the major degradation mechanism of failure for various components operating at high temperature. Protective coatings are used to improve the oxidation resistance of such component. In the present investigation, Al2O3 and Ni-20Cr coatings have been deposited on SAE431 boiler steel by Detonation Gun Spraying Method. The oxidation performance of Al2O3 and Ni-20Cr coated as well as uncoated SAE-431 steel has been evaluated in air under cyclic conditions at an elevated temperatures of 8000C. Al2O3 coating on SAE431 boiler steel has shown approximately 26% improvement in the oxidation resistance of SAE431 steel whereas Ni-20Cr coating on SAE431 boiler steel has indicated about 21% improvement in the oxidation resistance as compared to the uncoated SAE431 boiler steel.

Sustainable development is the thought process behind well being of humanity. It expects the sustenance of mankind on earth. As per the idea of sustainable development lays stress on encompassing all the three parameters of sustainability, meaning balance between socio-economic activities with environment ultimately, the process should enhance the quality of human life. The development should encourage human bonding in the society and feeling of neighbourhood satisfaction by fulfilling community needs. Finally sustainable development is devolvement which accompanies welfare of the society by including some design elements in the safe built environment. Some alterations in physical environment can bring in the feeling of safety for the society.

Analysis of Security Algorithms used in E-Commerce and ATM Transactions |
E-commerce is trading ofproducts or services using computer and Internet. It mainly revolves around the Internet for it‟s functioning. Virtual mall, buying selling websites or domains, providing secure business transactions, collection and use of demographic data comes under e- commerce. E-commerce security is an important part for the framework and it is applied to the components that affect the vendor and the end user through their daily payment and interaction with business. Since it involves various transactions, E-commerce offers the banking industry a great opportunity but it also creates various risks and security threats. We can say in the near future people would like to carry their transactions though mobile devices instead of carrying currency in their wallets. Due to this the security of sensitive customer information is necessary. Thereare many security protocols and algorithms used in securing credit card transactions over the Internet and we will discuss and analyze the major ones.

Expositions on the Variation of Torsional-Distortional Stresses and Deformations in Box Girder Bridges | ||||||||||||
In this work a single cell and a double cell mono symmetric box girder study profile with the same cross sectional (enclosed) area and same material thickness were used to obtain the effect of sectorial properties on the distortional bending stresses and deformation of mono-symmetric box girders. The principles of Vlasov's theory of thin walled plates were used to obtain the torsional-distortional equilibrium equation for the analysis of the study profiles. The distortional bending stresses for the profiles were obtained by numerical differentiation of the warping function to obtain the distortion diagrasm which formed the base system for evaluation of the distortional bending moments. By solving the fourth order differential equations for torsional-distortional equilibrium the deformations of the study profiles were obtained. The warping functions, the distortion diagrams, the distortional bending moments and the torsional and distortional deformations of the study profiles were critically examined and conclusions were made.

Experimental Study of Material Removal Efficiency in EDM Using Various Types of Dielectric Oil | ||||||||||||
The machining process in electrical discharge machining (EDM) consists of a melting process and a removal process. A region of the workpiece surface heated by the discharge plasma is melted and a portion of the melted region is removed from the workpiece body. The rest of the melted region remains on the workpiece surface and re-solidified as a white layer. In previous research, to evaluate the removal ability, a ratio of the removal volume to the melted volume is defined as the material removal efficiency. In this study, the material removal efficiency was investigated to develop an understanding of the machining mechanism in EDM. As a result of experiments, it is found that the material removal efficiencies show almost the same value, whereas the removal volume varies with the type of dielectric oil or the discharge duration. To advance the study about the machining mechanism in EDM, the simulation for the workpiece temperature distribution, considering the effect of the type of dielectric oil or the discharge duration, should be conducted further.

Joint State and Parameter Estimation by Extended Kalman Filter (EKF) technique | ||||||||||||
In order to increase power system stability and reliability during and after disturbances, power grid global and local controllers must be developed. SCADA system provides steady and low sampling density. To remove these limitation PMUs are being rapidly adopted worldwide. Dynamic states of power system can be estimated using EKF. This requires field excitation as input which may not available. As a result, the EKF with unknown inputs proposed for identifying and estimating the states and the unknown inputs of the synchronous machine.

Intelligent learning management system starters |
learning management system (lms) is increasingly gaining popularity in the academic community as a means of delivering e-learning contents. Simply placing lecture notes and videos among other contents on lmss do not particularly train the best. This situation could be improved with intelligent tutoring systems (itss) integration into preferred lms to make it more adaptive and effective, through enhanced student participation and learning. This work aims, therefore, to create a starter model and a model java its integrated preferred lms. The its integrated lms starter model was proposed through augmentation and a fluid iterative cycle of awareness, suggestion, development, evaluation and conclusion. Known open/inexpensive, tried and tested popular lmss were evaluated at cms matrix site, and complemented. Java its integrated moodle (preferred), employing certain architectural framework of its integrated lms, was created following the spiral model of software development.

Content Based Video Retrieval Using Integrated Feature Extraction and Personalization of Results | ||||||||||||
Traditional video retrieval methods fail to meet technical challenges due to large and rapid growth of multimedia data, demanding effective retrieval systems. In the last decade Content Based Video Retrieval (CBVR) has become more and more popular. The amount of lecture video data on the Worldwide Web (WWW) is growing rapidly. Therefore, a more efficient method for video retrieval in WWW or within large lecture video archives is urgently needed. This paper presents an implementation of automated video indexing and video search in large videodatabase. First of all, we apply automatic video segmentation and key-frame detection to extract the frames from video. At next, we extract textual keywords by applying on video i.e. Optical Character Recognition (OCR) technology on key-frames and Automatic Speech Recognition (ASR) on audio tracks of that video. At next, we also extractingcolour, texture and edge detector features from different method. At last, we integrate all the keywords and features which has extracted from above techniques for searching purpose.Finallysearch similarity measure is applied to retrieve the best matchingcorresponding videos are presented as output from database. Additionally we are providing Re-ranking of results as per users interest in original result.

Treatment of Waste Water from Organic Fraction Incineration of Municipal Solid Waste (MSW) By Evaporation-Absorption Process | ||||||||||||
Evaporation is one of treatment alternatives of waste water from condensation of vapour in flue gas or from flue gas scrubber system of an incinerator. The waste water contains tar and heavy metals which are toxic and must be separated, before discharged to environment or recycled. Due to the relatively low efficiency of the evaporation process, a combination of the evaporation-absorption process is developed to increase the efficiency. The aim of this research is to study the separation efficiency of tar from the tar-water mixture from organic fraction incineration of garbage by evaporation-absorption process, and compared it with the evaporation process. The evaporation process was performed by evaporating the waste water directly, while the evaporation-absorption process was carried out by evaporating the waste water before it had been mixed with palm oil as an absorbent. The results showed that the efficiency to separate the heavy tar of the evaporation process was 73.27% compared to the combination of evaporation-absorption that was 98.82%. Meanwhile, for the separation of the light tar, the efficiencies of both process types were almost the same. This system can be integrated with the incinerator for the treatment of flue gases and waste water generated from the burning of organic fraction of MSW.

Seismic Drift Consideration in soft storied RCC buildings: A Critical Review | ||||||||||||
Reinforced concrete frame buildings are becoming increasingly common in urban India. Many such buildings constructed in recent times have a special feature – the ground storey is left open for the purpose of parking, i.e., columns in the ground floor do not have any partition walls (of either masonry or Reinforced concrete) between them. Such buildings are often called open ground storey buildings. The relative horizontal displacement in the ground storey is much larger than storeys above it. The total horizontal earthquake force it can carry in the ground storey is significantly smaller than storeys above it. The soft or weak storey may exist at any storey level other than ground storey level. The presence of walls in upper storeys makes them much stiffer than the open ground storey. Still Multi storey reinforced concrete buildings are continuing to be built in India which has open ground storeys. It is imperative to know the behavior of soft storey building to the seismic load for designing various retrofit strategies. Hence it is important to study and understand the response of such buildings and make such buildings earthquake resistant based on the study to prevent their collapse and to save the loss of life and property.

Study of Macro level Properties of SCC using GGBS and Lime stone powder | ||||||||||||
One of the major environmental concerns is the disposal of the waste materials and utilization of industrial by products. Lime stone quarries will produce millions of tons waste dust powder every year. Having considerable high degree of fineness in comparision to cement this material may be utilized as a partial replacement to cement. For this purpose an experiment is conducted to investigate the possibility of using lime stone powder in the production of SCC with combined use GGBS and how it affects the fresh and mechanical properties of SCC. First SCC is made by replacing cement with GGBS in percentages like 10, 20, 30, 40, 50 and by taking the optimum mix with GGBS lime stone powder is blended to mix in percentages like 5, 10, 15, 20 as a partial replacement to cement. Test results shows that the SCC mix with combination of 30% GGBS and 15% limestone powder gives maximum compressive strength and fresh properties are also in the limits prescribed by the EFNARC.

Importance of Measurements in Smart Grid |
The need to get reliable supply, independence from fossil fuels, and capability to provide clean energy at a fixed and lower cost, the existing power grid structure is transforming into Smart Grid. The development of a smart energy distribution grid is a current goal of many nations. A Smart Grid should have new capabilities such as self-healing, high reliability, energy management, and real-time pricing. This new era of smart future grid will lead to major changes in existing technologies at generation, transmission and distribution levels. The incorporation of renewable energy resources and distribution generators in the existing grid will increase the complexity, optimization problems and instability of the system. This will lead to a paradigm shift in the instrumentation and control requirements for Smart Grids for high quality, stable and reliable electricity supply of power. The monitoring of the grid system state and stability relies on the availability of reliable measurement of data. In this paper the measurement areas that highlight new measurement challenges, development of the Smart Meters and the critical parameters of electric energy to be monitored for improving the reliability of power systems has been discussed.

"MS-Extractor: An Innovative Approach to Extract Microsatellites on "Y‟ Chromosome" | ||||||||||||
Simple Sequence Repeats (SSR), also known as Microsatellites, have been extensively used as molecular markers due to their abundance and high degree of polymorphism. The nucleotide sequences of polymorphic forms of the same gene should be 99.9% identical. So, Microsatellites extraction from the Gene is crucial. However, Microsatellites repeat count is compared, if they differ largely, he has some disorder. The Y chromosome likely contains 50 to 60 genes that provide instructions for making proteins. Because only males have the Y chromosome, the genes on this chromosome tend to be involved in male sex determination and development. Several Microsatellite Extractors exist and they fail to extract microsatellites on large data sets of giga bytes and tera bytes in size. The proposed tool "MS-Extractor: An Innovative Approach to extract Microsatellites on "Y‟ Chromosome" can extract both Perfect as well as Imperfect Microsatellites from large data sets of human genome "Y‟. The proposed system uses string matching with sliding window approach to locate Microsatellites and extracts them.

Moon-bounce: A Boon for VHF Dxing | ||||||||||||
Amateurs Radio operator, also known as HAM communicates with other HAMs through Radio waves. Wireless communication in which Moon is used as natural satellite is called Moon-bounce or EME (Earth -Moon-Earth) technique. Long distance communication (DXing) using Very High Frequency (VHF) operated amateur HAM radio was difficult. Even with the modest setup having good transceiver, power amplifier and high gain antenna with high directivity, VHF DXing is possible. Generally 2X11 YAGI antenna along with rotor to set horizontal and vertical angle is used. Moon tracking software gives exact location, visibility of Moon at both the stations and other vital data to acquire real time position of moon.

Simulated Analysis of Resonant Frequency Converter Using Different Tank Circuits. | ||||||||||||
LLC resonant frequency converter is basically a combo of series as well as parallel resonant ckt. For LCC resonant converter it is associated with a disadvantage that, though it has two resonant frequencies, the lower resonant frequency is in ZCS region [5]. For this application, we are not able to design the converter working at this resonant frequency. LLC resonant converter existed for a very long time but because of unknown characteristic of this converter it was used as a series resonant converter with basically a passive (resistive) load. . Here, it was designed to operate in switching frequency higher than resonant frequency of the series resonant tank of Lr and Cr converter acts very similar to Series Resonant Converter. The benefit of LLC resonant converter is narrow switching frequency range with light load[6] . Basically, the control ckt plays a very imp. role and hence 555 Timer used here provides a perfect square wave as the control ckt provides no slew rate which makes the square wave really strong and impenetrable. The dead band circuit provides the exclusive dead band in micro seconds so as to avoid the simultaneous firing of two pairs of IGBT's where one pair switches off and the other on for a slightest period of time. Hence, the isolator ckt here is associated with each and every ckt used because it acts as a driver and an isolation to each of the IGBT is provided with one exclusive transformer supply[3]. The IGBT's are fired using the appropriate signal using the previous boards and hence at last a high frequency rectifier ckt with a filtering capacitor is used to get an exact dc waveform .The basic goal of this particular analysis is to observe the wave forms and characteristics of converters with differently positioned passive elements in the form of tank circuits. The supported simulation is done through PSIM 6.0 software tool.
