In communication, data can be in any form. There are many programs that continuously keep watch on the secret information while transferring the messages from one place to other. In many cases such secret messages attacked by opponents and could be misused. So there is need to send data in concealed form. Steganography means Covered Writing. Cryptography means secret writing. Steganography conceals the data or information in such a way that nobody can see the hidden message or even its existence can’t be predicted. There are several existing techniques of data hiding like RDH-EI and LSB but all these techniques have limited amount of data hiding capacity. BPCS (Bit Plane Complexity Segmentation) Steganography is a technique that provides high data hiding capacity. In BPCS data is hidden into the bit planes of the cover image. Basically Bit Plane Complexity Segmentation algorithm is depends on the characteristics of HVS (human vision system ) in which a human not able to see any information in more complex blocks/binary patterns, So that secret data is placed into all complex blocks/binary patterns. For cryptography purpose this paper uses standard AES algorithm. The main aim of this paper is to provide the robust system which embed the secrete data into multimedia file using BPCS and gains security which avoids the attention of hackers and hacking tools from secret information which is concealed into multimedia file.

Since dentistry is a man machine system, it does require ergonomic and engineering intervention to get maximum man machine efficiency. In history dentistry was analyzed as a man machine system in pure engineering terms ignoring its ergonomic aspect. Dentistry as a field of study for ergonomics was identified by T. M. Khalil in his paper, “Dentistry: A Growing Domain for Ergonomics”. [1]. Taking inspiration from this paper a study was conducted in Indian dental scenario to access the possible possibilities of ergonomic interventions in field of dentistry. A multidisciplinary and multi directional study of dental practitioners and students, practicing in a typical day was conducted for three consecutive days. During this the workplace ergonomics, arrangement of equipment and instruments, on work videography of dental practitioners, students and patients was done with consent. The results shows that the dentists are prone to musculoskeletal hazard. Working in awkward posture with curved back, neck bent and head forward to gain clear vision and access to patient’s mouth and sitting in this posture for prolonged time increases the risk of work related musculoskeletal disorders (WMSDs).

In modern backup systems, Deduplication plays a vital role in the elimination of duplicate data in a storage system which one of the technique to reduce storage costs. Deduplication divides a backup stream into variable sized chunks of data used to map stored chunks to their physical addresses. These chunks of data are physically distributed and create a problem known as fragmentation. Primarily fragmentation categorized into sparse and out-of-order containers. The sparse container adversely affects the performance while restoring the database and garbage collection effectively, while the out-of-order container brings an adverse effect on the performance issue if the restore cache built is small. To minimize the fragmentation problem, we implement the History-Aware Rewriting algorithm (HAR) and Cache-Aware Filter (CAF). HAR will collect the historical information in backup systems to identify and reduce sparse containers, and CAF to restore cache knowledge to find the out-of-order containers that impacts restore performance. We exploit Container-Marker Algorithm (CMA) to gather valid containers instead of valid chunks which help in garbage collection. My results help to prove how HAR, CMA improves the restore performance.

Wireless communication is also referred to as the future trends that are used to communicate between transmitter and receiver. Modulation has been done once signal is generated in each multiple sub carriers to send it over the channel. OFDM, SCFDMA and other modulation schemes are being used and reviewed. OFDM is a method that uses multiple sub-carriers to transfer the data through the channel. The data is being transferred over several or different channels. The carriers of the channels are orthogonal or independent to the signals. To achieve it, carrier must be placed exactly at the nulls modulation spectra of adjacent signals. SCDMA use the STBC codes to solve the problem of ICI. STBC stands for Space Time Block Coding. STBC is used to transfer the multiple copies of data to more than one antenna. It is used in Wireless communication for achieving the transferred data at more than one receiver’s end. In the proposed system modulation of the signal is performed, addition of Cyclic prefix has been done to obtain high performance data transform and use bandwidth efficiently. Proposed method evaluates STBC code to send single data to multiple routes for the quality enhancement of the signal. Transmission has been done between the receiver and the transmitter where each side involves separately performing their operations. As in the existing system FFT block was not included due to which signal has been distort whereas in the proposed system this DFT block is added before the IDFT block that will help to retain the signal quality. Comparison has been performed through taking signal and performance is evaluated in this thesis to check the efficiency of individual approach.

Compression Springs plays vital role in industrial field. Compression spring or coil spring is used to resist axial compressive force. The available different shapes are cylindrical, conical, tapered, concave, convex. By changing spring parameters such as spring constant, spring ends, material & material finish, wire diameter, pitch, free length, outer diameter allows meeting industrial requirement. The Sheet metal industry needs 'die' for manufacturing stamped components. The stripper for the die uses a set of coiled springs sandwiched between the top plate and the stripper. It operates under high frequency of cyclic operation, typically 30 to 60 cycles per min (with a maximum of about 300 strokes per minute). High spring rate is the characteristic feature of this application. This poses a challenge for designing an appropriate spring for the given application & its predefined period. For designing proper compression spring, it needs to be considering all load, movement and available space for spring. Though this is an option of selecting the nearest available specification for the standard variety of spring. The spring is designed and modeled using CAD software. This further evaluated using FEA software for static, fatigue analysis for cyclic loading and produces the best suitable compression spring.

Now in these days the social network becomes a daily habit for all. Most of the young and teen agers are consuming their time on social media. Due to frequent reachability of users the different marketing companies are also usages this platform for publishing advertises. But not only legitimate users are available in this platform, sometimes this platform is also used for abusing someone or harshen someone. Therefore, it is need to identify the sensitive contents on the social media platforms before publishing the contents. A number of different kinds of approaches are available for scanning the contents, but all these techniques are much time consuming. Therefore, these techniques are not directly used with the social networks. In order to find an efficient technique an effort is presented in this work. The proposed technique is an enhancement over the traditional figure print scan method for sensitive content evaluation. The proposed technique incorporates the NLP (natural language processing) parsers for identifying the sensitive features. The sensitive features are considered here as the noun words in any twit, because in most of the cases the identity of person or places are used for misguiding the social network users. Additionally, in place of linear search technique, a random index scan method is introduced for improving the time consumption of the traditional approaches. Because this technique produces the results equal as the linear search in worst case. The proposed technique is evaluated over the twitter data using the Hadoop, Strom and twitter API implementation. After the successfully implementation the technique is compared with the traditional available technique over the time and space complexity. The experimental results show the performance in terms of time requirement is three times efficient than the traditional approach of sensitivity scan.

In four-server secret word verified key trade (PAKE) convention, a client uses its secret word and stores two sections of its secret key in the four servers, separately, and the four servers at that point work together to confirm the client without knowing the secret key of the client. For accomplishing the certain verification we can develop ID2S PAKE conventions. The character based encryption plot with two gathering PAKE convention have accomplishes high security. Right now one server is traded off by an adversary and the mystery key of the client is permitted to remain secure. In this paper it shows four compilers that can change any four party PAKE convention to a two-server PAKE convention on the given personality based cryptography, known as ID2S PAKE convention. By the assistance of compilers, we can manufacture ID2S PAKE conventions which satisfy undeniable validation. As whatever time frame the crucial two-party PAKE convention and character based encryption or stamp plot have certifiable security without self-assertive prophets, the ID2S PAKE conventions worked by the compilers can be ended up being secure without self-assertive prophets.
