Parametric Optimization of Hot Machining Process for Aisi4140 Material Using Grey Relational Technique.
In the industries, there is a need of materials with very high hardness and shear strength in order to satisfy industrial requirements. So many materials which satisfy the properties are manufactured. Machining of such materials with conventional method of machining was proved to be very costly as these materials greatly affect the tool life. So to decrease tool wear, power consumed and increase surface finish Hot Machining can be used. The L9 orthogonal array of a Taguchi experiment is selected for four parameters (speed, feed rate, depth of cut and temperature) with three levels (low, medium, and high) in optimizing the hot machining turning parameters on lathe.

Robust Approach of Compressing Images Using DCT and Analysis of Parameters PSNR, CR
Image compression is one of the tedious tasks in the field of image transmission via internet and to store in binary or digital form on computers and other storage devices. The necessity of bandwidth of channel relies on many aspects like data and size of file to be transferred. Compressing an image is significantly different than compressing raw binary data. If we used general or outdated technique to compression images then result would be not optimal as it should be. This is because images have definitely statistical properties which can be triggered or exploited by encoders which are implemented or design for them. In image we have to give up some fine details for the sake of saving a little more bandwidth or storage space. So we can say that lossy compression technology. In this dissertation compression of digital images are done with the help of DCT. Several encoding technique have also been used together with DCT to improve the performance of compression. A computational analysis of picture quality is also made with respect to compression ratio and PSNR.

Personality Based Indian Song Suggestions
Songs play a very important role in living beings. Dr. Jagdish Chandra Bose, the pioneer of music impact on plant growth had experimented & shown the results that even plants respond positively to the nice music. We, the people generally tend to hear only the trending songs & listen to sings under peer influence. But people should hear right kind of music suitable to their personality traits in order to bear the musical health benefits. An experiment was carried out where participants were asked to answer personality related questionnaire & were asked about their music preferences. The study shows that among the five traits each trait has got to do something with the Indian music genres. The App has been tested over 70 people. Till date we knew music has some impact but with this study which music/ song genres are suitable to what kind of personalities has been attempted.

Design and Simulation Result Analysis of Data Aggregation in Ns2 for WSN with Security
Energy efficiency is an important metric in resource constrained wireless sensor networks (WSN). Multiple approaches such as duty cycling, energy optimal scheduling, energy aware routing and data aggregation can be availed to reduce energy consumption throughout the network. This thesis addresses the data aggregation during routing since the energy expended in transmitting a single data bit is several orders of magnitude higher than it is required for a single 32 bit computation. Therefore, in the first paper, a novel nonlinear adaptive pulse coded modulation-based compression (NADPCMC) scheme is proposed for data aggregation. A rigorous analytical development of the proposed scheme is presented by using Lyapunov theory. Satisfactory performance of the proposed scheme is demonstrated when compared to the available compression schemes in NS-2 environment through several data sets. Data aggregation is achieved by iteratively applying the proposed compression scheme at the cluster heads. The second paper on the other hand deals with the hardware verification of the proposed data aggregation scheme in the presence of a Multi-interface Multi-Channel Routing Protocol (MMCR). Since sensor nodes are equipped with radios that can operate on multiple non-interfering channels, bandwidth availability on each channel is used to determine the appropriate channel for data transmission, thus increasing the throughput. MMCR uses a metric defined by throughput, end-to-end delay and energy utilization to select Multi-Point Relay (MPR) nodes to forward data packets in each channel while minimizing packet losses due to interference. Further, the proposed compression and aggregation are performed to further improve the energy savings and network lifetime. Besides this we also applied RSA security algorithm for encryption and decryption.

Design of Industrial Steel Building by Limit State Method
In this project work it is proposed to carry out the design of an industrial steel storage shed. The four requirements named as Utility, safety, economical and elegance must be fulfilled for a structural design to be satisfactory. This project presents a study on behavior and economy of roof trusses columns and purlins by comparison of limit state and working stress method. Roof trusses and purlins are integral part of an industrial building. This project presents a study on behavior and economical of fink type roof trusses, beam section purlins by comparison of limit state and working stress method. This study involves in examination of theoretical investigations of specimens in series. Overall two methods were designed and comparison of all the internal force, economical, and hence, to evaluate the co-existing moments and shear forces at the critical cross-section with same configuration area by keeping all other parameters constant. The theoretical data are calculated using Indian Standard code IS 875-1987 (part I), IS 875-1987 (part II), IS 875-1987 (part III), IS 800 – 2007 using limit state method, IS 800- 1984 using working stress method and the section properties of the specimens are obtained using steel table. The project aims to provide which method is economical, high bending strength, more load carrying capacity and high flexural strength. The studies reveal that the theoretical investigations limit state method design is high bending strength, high load caring capacity, minimum deflection and minimum local buckling& distortional buckling compare to the working stress method.

Seismic Analysis of Office Building with Prestressed Flat
High rise building structures are both a necessity and a matter of sophistication and pride for structural engineers. Buildings crossing 25 to 30 storeys are a common phenomenon these days. But what happens to a structure as it crosses these height limits? Forces of nature in the form of earthquakes and cyclones starts playing brutal games with the structures. Higher the structure goes, higher it attracts the forces and wrath of nature in the form of seismic force. Seismic force, predominantly being an inertia force depends on the mass of the structure. As the mass of the structure increases the seismic forces also increase causing the requirement of even heavier sections to counter that heavy forces. And these heavy sections further increase the mass of the structure leading to even heavier seismic forces. Structural designers are met with huge challenge to balance these contradictory physical phenomena to make the structure safe. The structure no more can afford to be rigid. This introduces the concept of ductility. The structures are made ductile, allowing it yield in order to dissipate the seismic forces. A framed structure can be easily made ductile by properly detailing of the reinforcement. But again, as the building height goes beyond a certain limit, these framed structure sections (columns) gets larger and larger to the extent that they are no more practically feasible in a structure. A flat slab is a one-way or two-way system with thickenings in the slab at the columns and load bearing walls called ‘drop panels’. Drop panels act as T-beams over the supports. They increase the shear capacity and the stiffness of the floor system under vertical loads, thus increasing the economical span range. A flat slab is a one-way or two-way system with thickenings in the slab at the columns and load bearing walls called ‘drop panels’ Figure 9. Drop panels act as T-beams over the supports. They increase the shear capacity and the stiffness of the floor system under vertical loads, thus increasing the economical span range. Here an attempt has been made to study the behaviour of different structures of reinforced concrete with different prestressed systems. Studies have been carried out on sample model structures and analysis has been carried out by ETABS software. It has been ensured to consider sample models that represent the current practices in structural design to include different structural configurations
