Latent Semantic Indexing Based SVM Model for Email Spam Classification

Internet plays a drastic role in part of communication nowadays but in e-mail, spam is the major problem. Email spam is unwanted, inappropriate or no longer wanted mails also known as junk email. To eliminate these spam mails, spam filtering methods are implemented using classification algorithms. Among various algorithms, Support Vector Machine (SVM) is used as an effective classifier for spam classification by various researchers. But, the accuracy level is not up to notable level so further. To improve the accuracy, Latent Semantic Indexing (LSI) is used as feature extraction method to select the suitable feature space. The hybrid model of spam mail classification can provide the effective results.

Cognitive Radio Transmission Based on Chip-level Space Time Block Coded MC-DSCDMA over Fast-Fading Channel

In this paper, a transmit diversity technique using chip level space time block coding (chip-STBC) is investigated for the downlink transmission of multicarrier direct sequence code division multiple access (MC-DS-CDMA) based cognitive radio base station. Synchronous transmission of multiple users’ signals over fast fading frequency selective Rayleigh channel is considered. Conventional symbol level space time block coding techniques cannot be applied in such channel conditions, since the coherence time of the channel will be less than the symbol period. Therefore, chip level STBC with chip level linear minimum mean square error frequency domain equalization (LMMSE-FDE) is utilized to achieve space-time diversity.

Suitability of Synthetic Fiber for Construction of Concrete Pavements

the

A pavement concrete undergoes dynamic loading and rigorous environmental conditions. Development of shrinkage cracks in plain cement concrete pavements is a major problem especially in tropical regions. To overcome this problem sometime the addition of synthetic fiber to the concrete mix is suggested. This paper briefly discusses the effects of the addition of polypropylene (PP) multifilament and fibrillated fibre on the properties of a paving grade concrete mix of compressive strength 48 MPa and flexural strength 5.4 MPa at 28-day. Concrete mixes containing different dosage of multifilament and fibrillated fiber besides one control mix were used. The important properties of the concrete relevant to its use in pavement such as flexural strength, drying shrinkage, and abrasion resistance etc. were evaluated.

Effect of ethanol blend addition on performance and emission of diesel engine operated with Jatropha & Pongamia methyl esters

This project aims at using ethanol as an alternate fuel for Direct Injection Compression Ignition engine and blending it with some lubricating oils to increase the lubricating property of ethanol. This replacement of conventional Diesel with ethanol requires some of the properties of ethanol to be altered. The corrosive nature of ethanol is very high that it may corrode the fuel pump system. In order to increase the lubricating property of ethanol, it is blended with some of the lubricating oils. Some of the preferred lubricating oils are methyl esters of Jatropha oil, Pongamia oil etc. Ethanol is blended with these lubricating oils to reduce the corrosive property of Ethanol.

Vegetable oil reverse micelle microemulsions as an alternative method for biodiesel production has been studied to eliminate transesterification reaction and avoid unpurified glycerol formation. The sorbitane oleate ester surfactants due to high solubilization capacity in oils have formed reverse micelle microemulsions with karanj oil and ethanol. The phase behavior of span 80 and 85 based Karanj oil-ethanol microemulsion have been studied with their physicochemical parameters i.e. density and viscosity for formulating optimized systems as biofuel. This review links two apparently unconnected subjects supporting strategies for sustainable biodiversity use and conservation of the Cerrado (Savannatype) biome in Brazil with the flavonoid astilbin from Dimorphandra mollis Benth. (Fabaceae) flowers. This plant is abundant in the Cerrado flowering from October to January. Larvae and hives of the honey bee Apis mellifera L., 1758 (Hymenoptera: Apidae) died after bee workers have pollinated crops of orange Citrus spp. (Rutaceae) near D. mollis in São Paulo State, Brazil, suggesting that bee workers might have collected pollen from D. mollis intoxicating themselves, other adults and the offspring. Pollen from D. mollis was collected and dried out of direct sunlight. Dichloromethane and methanol solutions were obtained from extracts of this pollen and the second was toxic to honey bees in the laboratory. In this study, an empirical relationship between the impact energy and compressive strength is developed using regression analysis. For this, simple, practical, and economical drop weight test was performed on fiber reinforced concrete which was based on the testing procedure recommended by ACI committee 544. Crimped steel fiber of 50 mm length and an aspect ratio of 50 was used as the reinforcing material in four different volume fractions such as 0%, 0.5%, 1.0% and 1.5% with water cement ratio of 0.42. The test results indicated that increasing volume fraction of fiber increased the impact resistance of concrete specimen. It is also found that the empirical relationship obtained from the regression analysis is accurate and preferable to evaluate the impact energy by using compressive strength of fiber reinforced concrete thus eliminating the drop weight test. Some new 4-{[(E)-{2-hydroxy-5-[(Z) substituted phenyldiazenyl] phenyl} methylidene] amino} benzenesulfonamides were synthesized by coupling of 4substituted phenylazo salicylaldehydes with different sulphanalamide derivatives. Electrochemical behaviour of 4-{[(E)-{2-hydroxy-5-[(Z) substituted phenyldiazenyl] phenyl} methylidene] amino} benzenesulphonamides have been studied in BrittonRobinson buffers of pH 2.5-12.0 at dropping mercury and glassy carbon electrode. All benzenesulphonamides gave 4-electron wave corresponding to the reduction of N=N- and -C=N- bonds at mercury electrode. On the basis of differential pulse polarography, cyclic voltammetry, IR, mass and 1H NMR spectral studies and product identification, a reduction mechanism has been suggested.

Ananta Saikia, Renganathan Sivabalan, Girish M Gore & Arun K Sikder

The flash powder composition is used in the fireworks industry to manufacture the firecracker which consists of pottasium nitrate, aluminium and sulphur powder in 75 microns range. During fireworks crackers bursting, more polluted gases are emitted and thus pollute the atmosphere. In this study, synthesis of flash powders and manufactured the fire crackers with the use of nano flash powders. The particle sizes of the chemicals are 139.7 nm for KNO3, 94.5 nm for Al and92.36 nm for S. The nano flash powders are mixed with micron powders in different ratios and crackers are manufactured. The residues are collected and analysed for the metal content. Also gas analysis is done for all the combination of crackers. SEM analysis of the residues is analysed. Results shows that crackers made of 100 % nano flash powder provide less quantity of sulphur dioxide and metal content. A novel and efficient method for the synthesis of various promising high energy materials (HEMs) like nitrotriazolone (NTO), 2,4,6,8,10,12-hexanitro2,4,6,8,10,12-hexaazaisowurtzitane (CL-20), bis (2,2-dinitropropyl) nitramine (BDNPN), 1,1-diamino-2,2-dinitro ethylene (FOX-7) etc. using metal nitrates/sulphuric acid as nitrating agent has been described successfully. The synthesized materials have been characterized using various spectroscopic techniques as well as thermal studies and the data obtained confirmed their structure. From the study it was revealed that this method certainly an alternative method of preparation of high energy materials (HEMs) in place of the conventional nitration mixture.

A Novel approach of the modified BET Isotherm towards continuous column study Rangabhashiyam S, Anu N, Giri Nangagopal M S and Selvaraju N *

Adsorption can be used to treat wastewater containing pollutants even at the low concentration in a very effective manner. The significance of the Langmuir, Brunauer Emmet Teller Isotherm was investigated for the perfect correlation with the experimental data. A theoretical one dimension dynamic model was proposed to understand the behavior of fixed bed with the assumption of straight through run mode of operation. The limitations associated with the application of classical Brunauer Emmet Teller to the liquid phase modeling were represented. The results were correlated using the theory and experimental observation available in the recently published literature through Mathematical derivation and MATLAB. The present study reveals that the modified Brunauer Emmet Teller isotherm posses the potential towards the applicability as Monolayer Langmuir adsorption isotherm under the condition of number of layer is equal to one.
