Characterisation of Fly Ash and Relevance of Pozzolanic Reactivity

Abstract: It is a very well known fact that the use of fly ash in masonry and concrete make the structures durable. Properties of Fly Ash depend upon coal source. For acceptability of fly ash in cement, mortar and concrete various specifications and standards are available. The Indian standard IS 3812: 2003(Part I and Part II) expects some physical and chemical properties similar to world standards, while differs in some, like lime reactivity test. As a part of research activity the authors have collected 23 different fly ash samples from various hoppers of three power stations near Nagpur. The samples were tested as per most of the provisions of IS 3812 and tests specified in IS 1727. Test results are compared with major world standards and specifications. Gain of strength is the most important character of fly ash, especially from the usage in cement and concrete. The paper discusses comparison of various standard specifications and interpretation of pozzolanic reactivity.

Low Voltage Low Dropout Regulator with Current Splitting Technique

Abstract: Integrated regulators are used for power management in modern portable devices There are many primary regulators and post regulators which converts high dc voltages, but they are unable to work on low voltage with low quiescent current A low-voltage low-dropout regulator with current splitting technique is proposed which converts a low-voltage of 1V to an output of 06 V with 90 nm CMOS technology A power noise cancellation mechanism is formed at rail-to-rail output stage of error amplifier (EA) which minimizes the size of power MOS transistor A transient accelerator (TA) is formed to reuse the part of EA which achieves high current efficiency Keywords: Fast Transient Response, High Power Supply Rejection, Low Dropout (LDO) Regulator, Low Input Voltage

An Enhanced Approach for XSS Attack Detection on Web Applications

Abstract: Programming security vulnerabilities have prompted numerous effective assaults on applications, particularly web applications, once a day. These assaults, including cross-site scripting, have caused harms for both web site proprietors and clients. Cross-site scripting vulnerabilities are anything but difficult to misuse however hard to alleviate. Numerous arrangements have been proposed for their recognition. In any case, the issue of cross-site scripting vulnerabilities present in web applications still perseveres. In this paper, we propose to investigate a methodology dependent on hereditary calculations that will most likely distinguish cross-site scripting vulnerabilities in the source code before an application is sent. The proposed methodology is, up until this point, just actualized and approved on web applications, in spite of the fact that it tends to be executed in other programming dialects with slight adjustments. Introductory assessments have shown promising outcomes.

Performance improvement of noise content video using Raspberry Pi

Abstract: This paper proposes the implementation of a service running on Raspberry Pi which captures video from the camera and streams it to processor, which processes it and displays on the screen. Implementation of this scenario needs following topics to be addressed. For controlling and capturing the video, Raspberry provides the console application raspivid which can be executed with parameters specifying how the video shall be captured. You can specify parameters like width, height or frames per seconds as if the video be produced to a file to out. The service application implemented in this example internally uses the raspivid. For video capturing the service starts raspivid and then reads incoming video data from raspivid's out. The service executes raspivid with above specified parameters. Live video data continuously coming from raspivid's out needs to be transferred across the network to the connected client. To transfer the data for inter-process communication the implementation uses the lightweight cross-platform library. The communication is based directly on duplex channels to avoid serialization or deserialization. It means the service application running on Raspberry Pi uses input duplex channel and the .NET client running on PC as output channel. When a raspivid's out provides chunk of video data, the service uses the duplex channels to send data to connected clients. Then it uses output channel to receive the video data and to notify it for further processing.

Combustion Synthesis of YAG:Nd: Structural, Luminescent Characterization and Influence of Si Doping

Abstract: Neodymium-doped yttrium aluminum garnet (YAG:Nd) powder was prepared by solution-combustion synthesis using aluminum nitrate, yttrium nitrate, neodymium nitrate, urea, and glycine as starting materials. The characteristic near-IR emission of Nd3+ at 1067 nm was found to maximize at a Nd3+ concentration of 1 mol %. The impact of Si4+ co-doping on the crystal structure, morphology, and photoluminescence has also been studied. In the presence of the dopant, the emission intensity enhanced by 21% at an optimal Si4+ content of YAG:Nd3+ phosphor, which can be attributed to improvement in crystallinity, formation of pure phase, and creation of color centers due to mismatch in ionic radii between parent and doped ions.
