Abstract:
This research has been out within the field of the barriers of advanced manufacturing technology. It has been goal to investigate the barriers affecting the implementation of AMT in the organisation. the work with this paper has been carried out in cooperation with machine well with the goal to create recommendation for the company in how they could implement AMT successfully in the company in order to answer the question what should a small industry focus on to implement the AMT concept successfully, an investigation in the two middle size industries in the Rajasthan (India) were visited. One interview was carried out with managers at both the two companies and a questionnaire was handed out to workers. The aim was to see if there were any large differences in the barriers of AMT which is applying in the company. The interview and questionnaire did show that a company should know about barriers of AMT & their inter relationship if they wanted to accomplish more in the organisation with tea work and get more busy from the employees. It is important that all workers know the vision and goal why a company is implementing AMT. Advanced manufacturing technology (AMT) has been viewed strategic weapon to gain competitive advantages by manufacturing organisation . The small and medium scale industries (SMISs) are under increasing pressure to adopt advanced manufacturing technology to be competitive or simply to survive. The successful implementation of AMT will requires the companies to have a workforce with higher level of skills, a flexible organizational structure and include a new culture in managing and training a workforce in the manufacturing industries. The ability of the workers to run multiple machines, stopping production when problem occur, communication of organizational goals and participation in idea generation and decision making are important in achieving a higher benefits of AMT. The SMIs have to increase the educational and supervision needs of the workers and also have a higher understanding of the technology to realize its potential. The proposed framework has synthesized previous studies and integrated related studies through conducting a complete literature review. This paper is a theoretical construction that synthesizes previous studies .this model can provide managers with practical solutions through granting in depth understanding of whole internal external technological and environmental and awarding empirical insight into overcoming barriers to the adoption and implementation of AMT.

Abstract:
Concrete is the most important component used in the construction industry throughout the world, where the fine aggregate is generally natural sand. The use of sand in construction activities results in the excessive mining. Due to excessive mining, natural resources are getting exhausted, results in increase in scour depth and sometimes flood possibility. Thus, it is becoming inevitable to use alternative material in concrete.Marble is one of the important materials used in the construction industry. Marble powder is produced from processing plants during the sawing and polishing of marble blocks and about 20 - 25% of the processed marble is turn into powder form. Disposal of the marble powder material from the marble industry is one of the environmental problems worldwide today.The present study is aimed at utilizing Waste marble powder construction industry itself as fine aggregate in concrete, replacing natural sand. The replacement is done partially and fully in the proportion 0%, 25%, 50% and 100% and its effect on properties of concrete were investigated.

Abstract:
Present days processing of the image compression is the main protective representation with considerable data process on each image progression. Traditionally more number of techniques were introduced for during efficient progression in image compression on the data set representation process of application development. A content owner encrypts the original uncompressed image using an encryption key. Then, a data hider may compress the least significant bits of the encrypted image using a data hiding key to create a sparse space to accommodate some additional data. With an encrypted image containing additional data, if a receiver has the data hiding key, receiver can extract the additional data though receiver does not know the image content. If the receiver has the encryption key, can decrypt the received data to obtain an image similar to the original one. If the receiver has both the data hiding key and the encryption key, can extract the additional data and recover the original content.\

Abstract:
Comparative analysis of the effects of cashew and mango extracts on the rheological properties of water based mud is presented. To control corrosion of drilling materials, corrosion inhibitor is usually used as one of the drilling mud additives. Such inhibitive substance can only be applied when it improves the rheological properties of the drilling mud. In this work, the mud samples were formulated in the absence and presence of various concentrations of cashew and mango extracts. The production method of the mud and the determination of its rheological and allied properties were carried out based on the mud production standards of American Petroleum Institute. From the analysis of the experimental results, cashew and mango leaves extracts are suitable additives for the production of water based mud. Mango leaves extract shows higher improvement of the rheological properties of the drilling mud. Use of plant leaves extracts as drilling mud additives will encourage local content development.
Keywords: Cashew extract, Mango extract, Mud, Rheological properties.

Abstract:
Most information concealing strategies install messages into the spread media to create the checked media by just altering the minimum critical piece of the spread and, accordingly, guarantee perceptual transparency. we enhanced the recursive development to approach the rate–distortion bound. Numerous RDH techniques have been proposed since it was presented. Fridrich and Goljan displayed an all inclusive structure for RDH, in which the installing methodology is partitioned into three stages. we sum up the technique in our past paper utilizing a decompression calculation as the coding plan for implanting information and demonstrate that the summed up codes can achieve the rate–distortion bound as long as the layering calculation achieves entropy. By the proposed double codes, we enhance three RDH plots that utilize parallel gimmick succession as spreads, i.e., a RS plan for spatial pictures, one plan for JPEG pictures, and an example substitution plan for twofold pictures. The exploratory results demonstrate that the novel codes can fundamentally diminish the em- padding bending. Moreover, by changing the histogram shift (HS) way, we additionally apply this coding technique to one plan that uses HS, demonstrating that the proposed codes could be likewise misused to enhance number operation-based plugins

Abstract:
In present days all our basic needs are relates with electricity. As the population increases, the demand for electricity is also tremendously increases. In the past, the entire electricity industry is under the control of government and also monopolized. But now, the power industry in many countries is moving rapidly from regulated conventional setup to deregulated environment. The transmission congestion is one of the technical problems that particularly appear in the deregulated power system. If congestion is not managed we face the problems of electricity price improvement and security and stability problems. Congestion relief can be handled using FACTS device such as TCSC, TCPAR where transmission capability will be improved. These FACTS devices are optimally placed on transmission system using Sensitivity approach method. The proposed method is carried out on Modified IEEE-14 bus system and IEEE-24 bus system Using Power World Simulator17 software.

Abstract:
Utility distribution networks have sensitive industrial loads and critical commercial operations suffer from various types of outages and service interruptions which can cost significant financial losses. Because of sensitivity of consumers on power quality and advancement in power electronics. Active power filter technology is the most efficient way to compensate reactive power and cancel out low order harmonics generated by nonlinear loads. The shunt active power filter was considered to be the most basic configuration for the APF. This paper reviews the basic principle of shunt active power filter, along with the current tracking circuit based on the instantaneous reactive power theory and the main circuit performing as an inverter with PWM hysteresis control. The instantaneous active and reactive current component (id-iq) method and instantaneous active and reactive power (p-q) method are two control strategies which are extensively used in active filters. A shunt active filter based on the instantaneous active and reactive current component (id-iq) method is proposed. This method aims to compensate harmonic and first harmonic unbalance. A Comprehensive control method is analyzed and a harmonic Compensation simulation is conducted, the result of which verifies The harmonic detection algorithm is well-proposed and the power Quality of the grid is overall-enhanced. The results are obtained using MATLAB/SIMULINK software.

Abstract:
In Data Storage as a Service (STaaS) cloud computing environment, the equipment used for business operations can be leased from a single service provider along with the application, and the related business data can be stored on equipment provided by the same service provider. This type of arrangement can help a company save on hardware and software infrastructure costs, but storing the company's data on the service provider's equipment raises the possibility that important business information may be improperly disclosed to others [1]. Some researchers have suggested that user data stored on a service-provider's equipment must be encrypted [2]. Encrypting data prior to storage is a common method of data protection, and service providers may be able to build firewalls to ensure that the decryption keys associated with encrypted user data are not disclosed to outsiders. However, if the decryption key and the encrypted data are held by the same service provider, it raises the possibility that high-level administrators within the service provider would have access to both the decryption key and the encrypted data, thus presenting a risk for the unauthorized disclosure of the user data. we in this paper provides an unique business model of cryptography where crypto keys are distributed across the user and the trusted third party(TTP) with adoption of such a model mainly the CSP insider attack an form of misuse of valuable user data can be treated secured.

Abstract:
Clutch is device which is used to transmit power one component to another. It is a device used to connect the driving shaft to a driven shaft, so that the driven shaft may be started or stopped at will, without stopping the driving shaft. A clutch thus provides an interruptible connection between two rotating shafts Clutches allow a high inertia load to be stated with a small power. The engine power transmitted to the system through the clutch. The failure of such a critical component during service can stall the whole application. The objective of present project is to do analysis on driven plate of a clutch which is often fails during the operation. In this present research work analysis is conducted on driven plate of a clutch used in TATA Vehicle. There are so many complaints are noted against the failure of clutch during heavy loads. The driven main plate failed normally during its operation due to cyclic loading. For this reason we designed the driven plate and modeled in Pro-E and analyzed using FEA package in the process of designing and analyzing the actual design is changed to lower down the failure values. And the design may suggest to the company.

Abstract:
When people talk about race cars or high-performance sports cars, the topic of turbochargers usually comes up. Turbochargers also appear on large diesel engines. A turbo can significantly boost an engine's horsepower without significantly increasing its weight, which is the huge benefit that makes turbos so popular. Turbochargers are a type of forced induction system. They compress the air flowing into the engine. The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. Here in this project we are designing the compressor wheel by using Pro-E and doing analysis by using FEA package. The main aim of the project is to increase the performance of the compressor wheel for this we are changing the material and also we are changing the existing design. By comparing the results we will get the best model from this data we suggests the design modifications to the company to improve the performance of the compressor wheel.

Abstract:
In present days the wireless communications are widely increases because of this reason spectrum utilization can be rapidly increased.For efficient usage of spectrum we can implement the Vacate on demand algorithm in different networks. CR users also need to sense the spectrum and vacate the channel upon the detection of the PU‟s presence to protectPUs from harmful interference. To achieve these fundamental CR functions, CR users usually coordinate with each other by using a common medium for control message exchange ensuring a priority of PUs over CR users. This paper presents the Vacate on Demand (VD) algorithm which enables dynamic spectrum access and ensures to vacate the assigned channel in case of PU activity and move the CR user to some other vacant channel to make spectrum available to PUs as well as to CR users. The basic idea is to use a ranking table of the available channels based on the PU activity detected on each channel. To improve the spectrum efficiency we can implement the Vacate on demand algorithm in MANET Network.

Abstract:
This paper presents a videodeblurring algorithm utilizing the high resolution information of adjacent unblurredframes.First, two motion-compensated predictors of a blurred frame are derived from its neighboring unblurred frames via bidirectional motion compensation. Then, an accurate blur kernel, which is difficult to directly obtain from the blurred frame itself, is computed between the predictors and the blurred frame. Next, a residual deconvolution is employed to reduce the ringing artifacts inherently caused by conventional deconvolution. The blur kernel estimation and deconvolution processes are iteratively performed for the deblurred frame. Experimental results show that the proposed algorithm provides sharper details and smaller artifacts than the state-of-the-art algorithms.

Abstract:
This thesis presents High frequency Soft Switching DC-DC boost Converter. The circuit consists of a general Boost Converter with an additional resonant circuit which has a switch, inductor, capacitor and a diode.In general Boost Converter circuits have snubber circuits where switching losses are dissipated in external passive resistors; which is known as hard switching. As the switching frequency of PWM converters is increased its switching losses and conduction losses also increases. This restricts the use of PWM technique. New Zero Voltage Transition-Zero Current Transition (ZVT-ZCT) PWM converter equipped with the snubber provides the most desirable features of both ZVT and ZCT converters presented previously. Moreover all semiconductors devices operate with soft switching and hence losses are reduced.
Keywords: Active snubber, ZCS, ZCT, Boost Converter, ZVS and ZVT.
