This research paper provides lossless data compression techniques and comparison between them. Data Compression is a process which reduces the size of data removing excessive information from it. It reduces the redundancy in data representation to decrease the storage required for that data and thus also reduces the communication cost by using the available bandwidth effectively. Data compression is important application in the area of file storage and distributed system. For different data formats like text, audio, video and image files there are different data compression techniques. Mainly there are two forms of data compression: - Lossy and Lossless. But in the lossless data compression, the integrity of data is to be preserved.

Basically, the term self-compacting was achieved by the use of admixtures in concrete. Admixtures introduced for SCC is different from other admixtures. Many manufactures produces varieties of SCC admixtures. In this project, Structuro 203 (Manufactured by Foscroc chemicals, India) was used as a superplasticiser. The main scope behind this study was to find out the behaviour of partial replacement of rice husk 10%, 20% & 30% by fine aggregate under the various SCC test (Slump flow test, L box test and V-funnel test) and hardened concrete test (Compression test and split tensile strength) using structuro 203 superplasticiser only. For all SCC test (Slump flow test, L box test and V-funnel test), 0% rice husk proportions gives better results when compared to other proportions of rice husk (10% and 20% and 30%). Similarly for Hardened concrete test on SCC after 28 days of curing, 0% rice husk proportions gives better strength when compared to other proportions of rice husk (10% and 20% and 30%). The dosage of structure 203 adopted was 4mL per kg of cement. This dosage was found on trial and error method in fresh concrete test of SCC.

Outlier identification previously, high-dimensional information displays Different tests coming about because of the “curse of dimensionalityâ€. An prevailing perspective may be that separation concentration, i.e., the propensity from claiming distances over high-dimensional information on turned into indiscernible, Hinders those identification about outliers by making distance-based strategies name at focuses as very nearly just as beneficial outliers. In this paper, we gatherings give proof supporting the assumption that such a see will be a really simple, toward demonstrating that distance-based strategies could. Handle All the more differentiating outlier scores previously, high-dimensional settings. Furthermore, we demonstrate that helter skelter dimensionality could have. An alternate impact, toward re-examining those ideas about opposite closest neighbours in the unsupervised outlier-detection connection. Namely, it might have been as of late watched that those dissemination about points’ reverse-neighbour tallies turns into skewed on secondary dimensions, bringing about. The wonder known as hubness. We furnish knowledge under how a few focuses (antihubs) show up extremely rarely to k-NN records about. Different points, What's more clarify those association between antihubs, outliers, and existing unsupervised outlier-detection systems .Toward.

Bug triage is a very much important step during bug fixing. Bug triage is the way toward fixing bug whose primary target is to accurately apportion a designer to another bug additionally taking care of. Many software organizations spend their too much cost in managing these bugs. To reduce the time cost in manual work and to improve the working of programmed bug triage, two procedures are connected in particular content characterization and double arrangement. In writing different papers address the issue of information diminishment for bug triage, i.e., how to lessen the scale and enhance the nature of bug information. By joining the example determination and the component choice calculations to at the same time reduce the information scale and upgrade the correctness of the bug reports in the bug triage. According to writing, need to build up a powerful model for doing information lessening on bug information set which will decrease the size of the information and increment the nature of the information, by minimizing the time and cost to get accurate result. System produces bug report and assigns that bug to appropriate developer according to his domain.

Pages: 221 - 225
We have designed this project to control the speed of a single phase induction motor by using cycloconvertor technique by thyristors. Induction motors in particular are very robust and therefore used in many domestic appliances such as washing machines, vacuum cleaners, water pumps, and used in industries as well. A.C. motors have the great advantages of being relatively inexpensive and very reliable. The induction motor is known as a constant-speed machine, the difficulty of varying its speed by a cost effective device is one of its main disadvantages. As the AC supply frequency cannot be changed, so this project uses a thyristor controlled cycloconverter which enables the control of speed in steps for an induction motor. A pair of slide switches is provided to select the desired speed range (F, F/2 and F/3) of operation of the induction motor. These switches are interfaced to the microcontroller. The status of the switches enables the microcontroller to deliver the pulses to trigger the thyristor in a dual bridge. Thus, the speed of the induction motor can be achieved in three steps i.e. (F, F/2 and F/3). This very concept can be further enhanced and implemented to control the speed of a three phase induction motor. It can also be coupled with firing angle control for any desired speed.

Pages: 226 - 231
This paper presents the design component aspect of a magnetically levitated vertical axis wind turbine. Using the effects of magnetic repulsion, spiral shaped wind turbine blades will be fitted on a rod for stability during rotation and suspended on magnets as a replacement for ball bearings which are normally used on conventional wind turbines. Maglev wind turbines have several advantages over conventional wind turbines. For instance, they’re able to use winds with starting speeds as low as 1.5 meters per second (m/s). Also, they could operate in winds exceeding 40 m/s. This type of wind setup does not require any significant land for installation, as its can be easily incorporated in rooftop, tower, and buildings. The VAWT is defined by an axis perpendicular to the unperturbed flow direction. It is considered that the blades carry their own weight leading to a reinforced root region. During operation the blades experience aerodynamic and inertia forces, which are deflecting the blades outwards, leading to an alternation of the aerodynamic loads. The interplay of load alternation and blade deflection could lead to a diverging flutter motion. After a fitting design is obtained, the blade motion has to be inspected for a safe use during operation.

Management of invasive alien insect, the papaya mealy bug, Paracoccus marginatus is of great importance because it even threatened tree species of economic importance. Secondary metabolites of the plants, including herbs and weeds are used as suitable alternative pesticide/insecticide and Calotropis gigantea is one of an ideal plant species for the extraction of pest resistant molecules. The present study focused on the exploration for an alternate ecofriendly plant based insecticide. The bioefficacy of the extracts of the flowers of Calotropis gigantea tested against papaya mealy bug infestation in Ailanthus excelsa found to have insecticidal activity (90-95%) at 2000 ppm within 24 hours of treatment. Individual phytochemical profiling of active botanicals revealed significant variation among pink and white colour flower for tannin, saponins, free fatty acids and alkaloids quantity. HPLC analysis also revealed high amounts of the bioactive compounds such as syringic acid, syringaldehyde and hydroxy benzoic. The insecticidal potential of the flower extracts of C. gigantea may be due to the presence of the individual phenolic compounds which are identified and quantified in significant amount.
