Wing is an important component of an aircraft, it helps to generate lift and also drag during take -off and landing, respectively. Wing`s vital role generating the lift above said our attempt to design a wing which has different sections i.e the wing is divided into several sections. This will increase the lift capacity of n aircraft while take off. We designed an airfoil keeping the NACA 2412 as base change some feature such as camber location. The wing is divided into five different sections. An actuator is used to change camber of a wing, and we considering the actuator responding 99%to change of the camber. A pneumatic actuator is used for varying the camber of an airfoil in each section of the wing for varying the angle of attack of the designed wing. The wing is designed by using an ANSYS& GAMBIT and the aerodynamic properties are found graphically by using FLUENT software. From the data we used, we aim at increasing the performance of an aircraft such as decreasing ground roll i.e decreasing take off distance and landing distance.

Steganography is the art and science of secret communications. It is the practice of encoding/embedding secret information in a way such that the subsistence of the information is invisible. The original documents can be referred to as cover text, cover image, or cover audio. After inserting the secret message it is referred to as stego medium. The disadvantages of the system lie in the fact that once the applicability of the system is known, it can be simply attacked. So, it is urgent to keep the application of the method to a particular dataset, secret. We have several methods of audio steganography to embed the text message in cover audio file. The main job is to send the messages to receivers by hiding the existence of the message. Due to the security issues, A new Hybrid algorithm has been used which consists of both Indian root and Reflection symmetry method in order to reduce the data and increase the security, hence making the decoding process difficult. The Proposed Hybrid Algorithm was successful in increasing the security of the particular document as it made the decoding difficult. It was also helpful to make the limited articles or sentences safe which were consumed by Indian root method. It became difficult to identify the number of bits as the encoding was done by both the processes Indian root as well as Reflection symmetry method. It helped to increase the number of hidden sentences as the decoding process was tough. As a future work, this solution can be enhanced by increasing the embedding data capacity. The work is only limited to the text data, which can be further done with multimedia data also. Some advanced steganography methods can be used to enhance the encoding decoding process.

Increased environmental awareness and depletion of resources are driving industry to develop viable alternative fuel from renewable resources that are environmentally more acceptable. Vegetable oil is a potential alternative fuel. The most detrimental properties of vegetable oils are its high viscosity and low volatility. Biodiesel is a renewable biodegradable and non-toxic fuels derived from vegetable oils and fats by trans-esterification process. As an alternative fuel biodiesel has attracted considerable attention during the past decades. The main hurdle to the commercialization of biodiesel is the cost of raw materials. Use of edible oils as biodiesel feedstock cost about 60-70% of raw materials cost. Non edible, inexpensive, low grade, high free fatty acid rice bran oil as a raw material by continuous trans-esterification process and purification of bio-active compounds from biodiesel as by-product are primary options considered to lower the cost of biodiesel. The present research is aimed to investigate experimentally the performance and exhaust emission characteristics of a direct injection diesel engine having standard piston fuelled with conventional diesel fuel, blend of diesel and rice bran oil biodiesel, and blends of diesel and rice bran oil biodiesel with varying proportions of Nano materials (Al2O3) as additives over the entire range of load on the engine. The piston in the diesel engine is replaced and then fuelled with the above said fuels. The performance parameters such as brake power, specific fuel consumption, thermal efficiencies are calculated based on the experimental analysis and engine emissions such as CO, HC, CO2, and NOx emissions are measured. The data has been analyzed and the results are presented and discussed in this project.

India is considered as one of the most disaster prone countries in the world. It has experienced several devastating earthquakes in the past which have resulted in a large number of deaths, injuries and severe property damage. There is a direct relationship between the damage of civil structures such as buildings to the number of casualties. Vulnerability of building is one of the major factors contributing to earthquake risk. As per National Building Code of India, half of the total money spent on construction is spent on buildings for various usage purposes. The frequent occurrence of damaging earthquakes clearly demonstrates the urgent need of study of earthquake risk assessment methods for disaster mitigation, disaster management, and emergency preparedness. In the present thesis seismic design of low-rise, mid-rise and high-rise buildings is carried out for zone V considering hard soil, medium soil and soft storey as per IS 1893 (Part1):2002, respectively. Pushover analysis is been performed using SAP2000 V17. Damage states are defined. Peak Ground Acceleration is taken as a hazard parameter and the demand statistics in terms of displacement are obtained for different sets of ground motion records which help to obtain a response matrix. A procedure for developing seismic fragility curves is been studied. The procedure for developing fragility curves can be explicitly performed using the Microsoft EXCEL. The fragility curves are used to represent the probabilities that the structural damages, under various level of seismic excitation, exceed specified damage states by means of earthquake intensity-damage relations and in turn will be helpful for can be utilized for prioritizing retrofit, pre-earthquake planning, and loss estimation tools such as cost-benefit analysis.

Delay Tolerant network is very large and sparse network compared to simple MANET .When two mobile node comes to each other within a range and exchange the information these scenario is called “contact” in DTN. Here in DTN end to end connectivity is not possible because of varying of contact time and very large network area. So the ordinary routing protocols of MANET like OSR, DSDV are not usable for DTN. Due to different nature of network DTN require some new protocols which can provide store and forward mechanism. Today DTN has large set of protocols like Epidemic, Spray and wit, PropHet, Fuzzy logic based and other more .In this paper we combine both the best performing protocol named Prophet and Fuzzy based routing and try to find better protocol compared to existing . Our proposed method transfers messages based on Probability and in inner logic it uses the fuzzy mechanism to priorities the message. This protocol gives good result in terms of average latency and delivery probability.
