Abstract

Structured Query Language (SQL) injection, in present scenario, emerges as one of the most challenging fact to effect on the online business, as it can expose all of the business transaction related sensitive information which is stored in online database, inclusive of most highly secured sensitive information such as credit card passwords , usernames, login ids, credentials, phone, email id etc. Structured Query Language injection remain a responsibility that when intruder gets the ability with SQL related queries which is passed to a back-end database. The query which is passed by the intruder to the data, can allow the query to data which is an assisting element with database and required operating system. Every SQL Query that allows the inputs from the attacker sides can defect our real web application. Intruder which attempts to insert defective SQL query into an entry field to extract the query so that they can dump the database or alter the database which is known as "code injection technique" and this type of attacker is also called attack vector for websites and usually used by any type of SQL database. Through this research paper, our endeavour is to understand the methodology of SQL injection and also to propose solution to prevent SQL Injection in one of the most vulnerable field of E commerce.

Abstract

Various techniques are used for improving in-situ ground conditions among which reinforcing the ground with stone column is one of the most versatile and cost effective technique. The presence of stone column on composite ground will impart lower compressibility and higher shear strength than that of native soil. Stone columns are used to improve the poor ground like soft marine clays, cohesive soils, silty soils, loose sand etc. This is the most popular technique used in flexible structures like road embankments, railway embankments and oil storage tanks. In the present study, the floating stone columns were reinforced by introducing lateral circular discs of geo-textile sheets within the column. Silica-Manganese slag which is a byproduct from ferro-alloy industries is used as the stone column material. The circular discs were placed at two different spacing (D and D/2) over varied reinforcement depths (0.25L, 0.5L, 0.75L and L). Laboratory tests have been performed on clay bed, ordinary floating stone column and reinforced stone columns to evaluate the improvement of load carrying capacity. After performing laboratory tests, the test results indicate that load carrying capacities of the stone columns reinforced with circular discs placed at D/2 spacing shows better performance than D spacing.

Abstract

Véhiculer Traffic is an inevitable phenomenon which is directly linked with the urban developmental society and cannot be ignored as it acts as a nervous system to the society in general and individuals in particular. Urban Traffic is emerging as an incurable threat to the modern society as there is a lack of efficient intelligent traffic management system. Prior attempts to use radio frequency spectrum, ultrasonic sensors and other alternatives proved to be ineffective as they are becoming crowded, that forced to develop an alternate means like wireless communication which can accommodate the exponentially increasing traffic demand. In this proposed research initiative, a Visible Light Communication (VLC) system is analyzed on its capabilities to provide an alternative to the current standards of wireless transfer of information using light from LEDs as the communication medium. The proposed system based upon the blinking of light-emitting diodes at a rapid rate such that the human eye will not notice the change in light illumination but a highly sensitive photodiode can read the behavioral changes and decode the information embedded within it. The proposed VLC methodology is also being tried to get implemented in intelligent wireless traffic management to resolve traffic logjams that usually occur in metro cities.

Abstract

What is anharmonicity? What happens to the energy levels of an anharmonic oscillator? What is dissociation energy? Many such questions can be answered by the computational method. The computational methods used for solving the second degree differential equation (Schroedinger's equation) is by Runge- Kutta fourth order method using Microsoft-Excel. For anharmonic oscillator, the accuracy of the results is fairly good.

Abstract

Fourier series and periodogram transform of three set of temperature data measured with constructed PIC 18F4520 based temperature meter were as interpreted. Measurement of 5-minute interval temperature variation with 3 LM34DZ sensors was made. The results show that Clay has the highest average Fourier transform (32.472) followed by loam (30.624) and sand (29.428). The periodogram analysis also varied in similar manner with clay having a mean periodogram 1899.97, loam 1694.84 and sand 1561.03. These show that temperature increasing most in clay caused higher values of Fourier and periodogram transforms. The average of the absolute deviation indicated loam has highest Fourier series changes (1.497) followed by sand (0.678) and clay (0.598) while the periodogram has deviation ranging from loam 165.48, sand 71.31 to clay 0.60. This indicates that loam soil has most sensitive response to temperature variations.

Keywords: Soil Data, Fourier Transform, Temperature, Periodogram, Variation.

Abstract

Micro turbines are becoming widely used for combined power generation and heat applications. Micro turbines have many advantages over piston generators such as low emissions less moving parts, accepts commercial fuels. Steam turbine cycle and operation of micro turbine was studied and reported. Different parts (Inlet. Storage, Nozzle, Rotor, coupling, outlet, clip, housing) of turbine are designed with the help of CATIA software. The turbine is of Axial input and axial output type. ANSYS is used for thermal analysis of a steam turbine and those results are extracted and following values are shown by applying known temperature when it is in working condition.

Abstract

Composites are versatile and convenient in diverse application such as automotive and aeronaut industry, constructional materials, civil and military applications and many more. Natural fiber composites are currently being used in mostly non-structural applications [1]. Natural fibers are being widely used to substitute artificial glass and carbon fibers in polymer composites. The aim of present work was to focus on the hybridization of natural fiber (jute) and synthetic fiber (E-glass) with polyester resin for applications in the aerospace industry [1]. The mechanical properties such as tensile, impact, flexural test and water absorption rate of hybrid glass/jute fiber reinforced polyester composites were determined. Laminates were fabricated by hand lay-up technique [2]. Then the mechanical properties of lamina prepared with different compositions of natural and synthetic fibers are compared. Total fiber weight fraction was maintained at 50%. Specimen preparation and testing was carried out as per ASTM standards [1], [2].

Keywords:natural fiber, synthetic fiber, polyester resin & fiber weight fraction 50%.
