Cold Formed steel (CFS) is the products made by rolling or pressing steel into semi finished or finished steel at relatively low temperature, commonly known as cold working method of strain hardening method, is dislocation generation within the crystal structure of the material . CFS products are found in all aspects of modern life, in home, shop, office, car body, petrol pump station. For the uses of structural members of greater length, cold rolled sections are used. Cold formed steel sections are most efficiently used with structures of moderate loads and span, in which circumstances these cold formed steel sections can be cheaper than hot rolled steel members. This investigation presents the experimental study of the behaviour of the flexural strength of CFS sections by using ‘Two Point Load’ method. Here two built up I sections were fabricated by using symmetric channel section with the help of bolts provided in the web part of the section. One of the built up I section was provided with angle stiffeners. The moment in the zone between the two point loads were same and that portion is known as pure bending zone. Flexural strength was increased by providing angle stiffener throughout the length of the sections at the spacing of 40 mm between two stiffeners.

Electronics waste was the by-product of plastic industries and additionally it's collected from native space and it contains junk TVs, Radio, CDs, Computers, Chips etc. coconut shells could be a by-product of coconut industries. This treatise shows study on the results of an investigation of result of plastic waste and coconut shells as coarse combination replacement in concrete combine. Concrete mixes containing varied contents of the coconut shells and plastic waste were ready and properties material and concrete like fineness modulus, water absorption, relative density, crushing worth, impact worth, abrasion worth, workability, compressive strength and flexural strength were determined. Concrete of M-40 grade is ready containing coconut shells and plastic waste as a partial replacement of coarse combination in concrete. Plastic waste and coarse combination that passes from 20mm sieve were mixed in concrete. One of the best methods for using waste as re-uses material. The cost of cement used in concrete works is on the increase and unaffordable, yet the need for housing and other constructions requiring this material keeps growing with increasing population, thus the need to find alternative binding materials that can be used solely or impartial replacement of cement. Coconut shells, which are an environmental pollutant, are collected and burnt in the open air (uncontrolled combustion) for three hours and that product is incinerated in muffle furnace at 800oC for 6hrs to produce coconut shell ash (CSA), which in turn was used as binding in partial replacement of cement in concrete production. Reduction of cement usage will reduce the production of cement which in turn cut the carbon dioxide emissions. The time has come for the review of progress made in the field of development of binary blended cement concrete and aggregates.

Corrugated metal roof cladding sheets are widely used in the industrial, residential and other buildings. In recent times corrugated metal roof cladding sheets are used in different geometries with different colors and have a wide range of applications in industrial structures. Corrugated steel sheets are frequently used for roofing and siding in buildings because the sheets are strong, lightweight, and easy to erect. In many cases they are used as shear diaphragms to replace conventional bracing and to stabilize entire structures or individual members such as columns and beams. These roofs during windstorms are subjected to intense fluctuating external pressures at windward roof edges. Loads on these areas can be gradually increased when combined with large positive internal pressures resulting from a breached windward wall, giving a large net uplift load, that is, large negative pressure is produced. In the present work design of arc tangent corrugated metal roof cladding sheets is attempted. The sectional properties of corrugated metal roof sheets of standard sizes as specified in IS277:1992 are computed using the method suggested by Blodgett. These standard sheets are subjected to wind loads as per IS 875:1997 (part 3) considering various parameters like height and width ratio of the building, angle of roof, wind zones, etc. Design tables are proposed which give the thickness of the arc corrugated sheets to resist safely the wind pressures due to the various combinations of the above parameters. A study is also made to find the influence of parameters like height to width ratio, width of building, roof angle, and basic wind speeds on the thickness of corrugated sheets. An attempt is also made to perform a linear static analysis of corrugated metal roofing sheets using the finite element software ANSYS 12.0. ‘Quad 8 node 183’ and ‘Brick 20 node 186’ elements are used for the discretization of the corrugated metal roof sheet. Stresses and deformations are computed for various corrugated metal roofing sheets. These values are found to be within the permissible limits. The numerical analysis suggests that the values of thickness given in the design tables are found to be adequate. The proposed design tables helps the designer to readily select a suitable thickness for the corrugated sheets in any wind zone of India. These tables are simple and convenient to use, and covers wide range of parameters encountered during the design.

The internet revolution has brought about a new way of expressing an opinion. It has become a medium through which people openly express their views on various subjects. These opinions contain useful information which can be utilised in many sectors which require constant customer feedback. Analysis of the opinion and it's classification into different classes is gradually produced as a key factor in decision-making These strategies usually attempt to extract the overall sentiment revealed in a sentence or document, either positive or negative, or somewhere in between. However, a downside of those strategies is that the information is often degraded, particularly in texts wherever a loss of information may occur due to mismatch of grammar in global language. In this paper, we tackle such situation Firstly with the implementation of Autocorrect feature, Secondly by acknowledging those Aspects based words which user writes in their home language. Then we apply our limited datasets to regain such words in its standard form. This method helps us to make our sentiment analysis more efficient.

A botnet is a collection of Internet-connected user computers (bots) infected by malicious software. They can be used for many malicious purposes, including to steal user’s personal data and passwords, attack public and private networks. With web applications and mobile apps piling up, people can access these applications anytime and anywhere with various devices. This evolution brings great convenience but also increases the probability of exposing passwords to botnet attacks. To make user authentication more secure by avoiding alphanumeric string which users tend to choose passwords either short or meaningful for easy memorization. To overcome this problem, we conduct a comprehensive survey of the existing graphical password techniques and proposed a new technique, proposed a novel authentication system called random pixel selection based on graphical password. Thereby, graphical authentication system called Random Pixel Selection can be done as one-time login indicator. The server would generate an image for user from the preselected images. By using Local Directional Number pattern, the features of the image are compared with generated image whether it is the user’s preselected image or depredation. The proposed system achieves better resistance to Botnet attacks while maintaining usability.

Achieving the improved digital communication systems with the cancellation of Non-Linear Distortion Noise is difficult task. Transmitting the digital video broadcasting through air interface through the interleaved Frequency- division multiple access scheme is possible. The comparative study is need to be done with the consideration of single carrier frequency division multiple access schemes and orthogonal FDMA schemes with the satellite uplink. The High Power Amplifiers should be operated in the K Band and S Band. The multiuser environment has to be developed to demonstrate the performance of synchronous and asynchronous LFDMA, IFDMA and OFDMA. The performance results of the Frequency Division Multiple access should be evaluated. In fact the Iterative Frequency Division Multiple Access is regarded as the outperforming scheme. The Inter Block Interference is causing the most sensitive degradation for asynchronous reception. To achieve the non-linear distortion in the large envelope fluctuations OFDMA is regarded as the best scheme among the other schemes like IFDMA and LFDMA. The proposed paper is focusing on the OFDMA performance and its better advantages in comparison with other schemes. The main aim of the paper is to suggest the best technique to reduce the linear and non-linear distortion in Integrated Terrestrial and Satellite Systems.
