The basic objectives behind using of fibers are to reduce cracking in concrete and to increase its strength. This experimental work was carried out to evaluate mechanical and durability properties of concrete made of 1% sisal fiber and 1% steel fiber for M20 grade concrete. Mechanical properties were studied by performing compression test (150mm×150mm size cubes), split tensile test (150mm diameter and 300mm length cylinders) and durability properties were studied by performing acid attack test (150mm×150mm size cubes). Various tests like Compression test and Split tensile test were performed on concrete cubes and concrete cylinders. It was observed that the strength and durability parameters were enhanced by using these fibers.

Energy absorbing steering column (Collapsible steering column) is a kind of steering column which minimizes the injury of the driver during a car accident by collapse or breaking particular part of system. Up to now, Collapsible Steering Column for low budget passenger car had no way to describe these ‘Collapse’ or ‘Slip’ by the Axial and Lateral Forces from driver. In this paper, I have created a collapsible steering column from rigid steering column using a Detailed FE model which can describe such collapse behavior.

The admixtures were varied by 5%, 10%, 15% for fly ash and for rice husk ash it is 4%, 8% and 12%. Different tests will be performed to check the properties of soil like swelling pressure, Plasticity index, liquid limit, specific gravity etc. for improved pavement works. It is concluded that the properties were enhanced with stabilized soil.

The key establishment difficulty is the most important issue and we learn the trouble of key organization for secure many to many communications for past several years. The difficulty is enthused by the propagation of huge level dispersed file systems behind parallel admission to manifold storage space plans. Our task focal points on the present Internet ordinary for such file systems that is parallel Network File System [pNFS], which creates employ of Kerberos to set up similar session keys flanked by clients and storage strategy. Our appraisal of the obtainable Kerberos bottom procedure demonstrates that it has a numeral of boundaries: (a) a metadata server make possible key swap over sandwiched between the clients and the storage devices has important workload that put a ceiling on the scalability of the procedure; (b) the procedure does not make available frontward confidentiality; (c) the metadata server produces itself all the assembly keys that are used between the clients and storage devices, and this intrinsically shows the way to key escrow. In this system, we suggest a assortment of authenticated key swap over procedures that are intended to tackle the above problems. We demonstrate that our procedures are competent of plummeting up to roughly 54% of the workload of the metadata server and concomitantly at the bottom of onward confidentiality and escrow freeness. All this necessitates only a minute portion of greater than before calculation in the clouds at the client.

Food, clothing and shelter are basic human needs. Beside food & clothing, shelter is a challenging task because according to KMPG, 11 crore houses will likely be required by 2022. To achieve this figure the speed of construction should be good enough. To avail the rapid construction, the most effective way is to provide shear walls instead of masonry walls. The main focus of this work is to analyze a R.C. building frame with R.C. shear walls at different locations of a building to know its the most efficient location. Shear wall is a specially designed structural walls incorporated in building to resist lateral forces that are produced in the plane of the wall due to seismic, wind and other forces. In this work, a 6 storey R.C. building frame has been analyzed for seismic zone-lll using staad pro. v8i (series 4) package. Special moment resisting frame (SMRF) and hard rock types are used in this work. There are some parameters considered such as node displacement, Maximum reactions and total weight of reinforcement to compare the results for different models. It has been judged that the model-IV is most efficient than other models.

Spring water is the main source of water providing life in the mountain region. Spring is the natural sources of ground water. Due to human and industrial activities this ground water is contaminated. This is very serious problems now a day. The analysis of water quality is very important to preserve and perfect the natural eco system. Physicochemical characteristics of spring water and some river water in dehradun city by taking water samples from 13 different stations. The study was carried out by collecting 10 spring water samples and 3 river water sample during April 2015 to May 2015. The results were compared with standards prescribed by ISI 10500-2012. Total 16 parameters were analysed. It was found that all spring water samples location is below the permissible limit of IS 10500:2012 were some of locations are above the acceptable limit.

Steganography is the art of covered or hidden writing. The main purpose of steganography is covert communication-to hide the existence of a message from a third party. Steganography is generally used to hide important information in a visible media mostly an image. A good approach to steganography must provide two attributes: high security against the different attacks called steganalysis, which is nothing but a technique used for detecting hidden information using steganography method and second is compression. Image compression not only reduces storage but also benefits transmission. In this paper the image steganography is achieved with enhanced security due to QR code and compression using DWT transform, without affecting the actual cover image due to addition of secret information which is in form of QR codes. The process for embedding the QR codes has been carried out using Embedding and Extraction algorithm which insures secure and fast transmission of stego image. These results validate the practical feasibility of the proposed method for security applications.

The urban traffic congestion has become a global phenomenon. Rapid urbanization and industrialization have caused an unprecedented revolution in growth of vehicles all over the world. This study presents, grade separation (over bridge) is provide in place of at grade signalized intersection. Ahmedabad city of Gujarat state is taken as study city. Shivaranjani signalized intersection on 132 ft ring road in the city of Ahmedabad is selected as a case study intersection. Various types of data are collected such as classified volume counts, signal cycle length, green time, phase plan etc. and number of lanes, lane width, grade, lane groups etc as a part of geometric data. The flow rate, saturation flow rate and its adjustment factors, capacity, volume to capacity ratio, critical lane group volume to capacity ratio, delay for lane groups, approaches and intersection as whole and delay comparison with level of service are calculated. This study proves that shivaranjani intersection must be required to convert in to grade separation.

India has a high number of deaths due to road accidents. India has the world's sixth-largest car market, but is still the only country among the global top ten car markets without proper new car safety regulation or testing programs. It is estimated that vehicles in India will cost 8-15% more resulting from compliance with these norms. However, harmonizing India's vehicle safety standards with global standards is expected to help automakers export locally produced cars globally. Since 2006, India has been having more road deaths per year than any other nation, with 230,000 dying annually. Bumpers play an important role in preventing the impact energy from being transferred to the automobile and passengers. Saving the impact energy in the bumper to be released in the environment reduces the damages of the automobile and passengers.

In recent days multilevel inverter(MLI) hold attractive features, in the area of high power medium voltage energy control though multilevel inverter has a number of advantages it has drawbacks in the vein of higher levels because of using more number of semiconductor switches. So in order to overcome this problem the new multilevel inverter is proposed with reduced number of switches. Switch topologies using carrier-based PWM techniques. These pulse width modulating (PWM) techniques include the phase disposition (PD) strategy, alternate phase opposition disposition (APOD) strategy. The modulating indices are evaluated for total harmonic distortion, form factor, crest factor, VRMS (fundamental) and distortion factor. This paper proposed the different carrier arrangement in order find out the less total harmonics distortion. The results are validated using MATLAB/SIMULINK software.
