Data Compression shrinks down a file so that it takes up less space. This is desirable for data storage and data communication. Storage space on disks is expensive so a file which occupies less disk space is "cheaper" than an uncompressed file. Smaller files are also desirable for data communication, because the smaller a file the faster it can be transferred. A compressed file appears to increase the speed of data transfer over an uncompressed file. Video compression is the last step before uploading your file online. As the name implies, compressing video reduces its file size. This is very important, because smaller files upload faster, save bandwidth and storage costs, and load quicker when played back. However, if video is compressed too much, the file can lose its detail, resolution, clarity, and much more. In this paper, the authors proposed new video compression techniques for surveillance videos and clinical medicine videos using ‘frame cut-off’ technique which is a novel approach in compression video where the movement is minimum. Also the authors implemented the proposed algorithm using Java technologies and MATLAB image processing tool and tested with CCTV and medical video processing such as EGC, Intensive Care Unit observations. The interpreted results show that the proposed algorithm compresses the videos five times better than the existing video compression techniques. The pros of the proposed algorithm are that it is well suited for the videos which have minimum movement, for example CCTV footage. The cons of this proposed solution is that the better results cannot be achieved for normal videos which have high movement such as cine movies. However, the content mining techniques are applied efficiently in order to increase the compression ratio and it can be further investigated to increase the high movement videos to compress better.

The terms Ubiquitous was first coined at the beginning of the 90's, by Xerox PARC and IBM respectively, and capture the realization that the computing focus was going to change from the PC to a more distributed, mobile and embedded form of computing. This paper will describe where software and hardware have combined to enable ubiquitous computing, where these systems have limitations and where the biggest challenges still remain.

This project presents a hybrid switching scheme for LLC series-resonant half-bridge (SRHB) dc-dc converter. The concept proposed hybrid switching scheme is changing the switching mode to improve power efficiency in a wide load range. The SRHB converter operates in three different switching modes depending on the output load condition.  This three switching schemes provides efficient operation of system at different load condition. The simulation and Digital control of the system facilitates the implementation of the proposed hybrid switching. Hence high efficiency is achieved with a constant output voltage over wide load range.

This work deals with the all the departments in steel plant steel melting shop(SMS) is one of the main department In purifying the steel. Molten pig iron(some times referred as “hot metal”) received from a blast furnace through open ladle(150T capacity) or torpedo ladle(300T capacity) is stored in “mixer” of  capacity(1300T capacity). The hot metal in open ladle can be directly poured into the mixer, where as the hot metal in the Tarpedo ladle has to be emptied into 2 No’s of open ladles. This method is called reloading of  Tarpedo ladle and this is in done in a pit (of side 7m x6m x5.85m depth) with vertical stand on either side of the open ladle in taken out from the pit and charged into mixer.

Now a days Consumers are becoming very much brand conscious and spending time and money trying out new product and services. Consumers are in seek of designer clothes, branded apparel, good quality product which not only satisfy their needs but also helps to groom their personality. Everyone prefer to wear branded clothes not only in their professional life but also in their social life. The purpose of this study is to examine the behaviour of consumer of Kota city on leading branded garments. It also helps to find out the major factors which helps the consumer to purchase branded apparel. The sample size of 100 people is going to be taken which includes both male and female of age 20 years to 40 years, this will help to study whether the consumers are really satisfied from their buying pattern, are they really loyal for their specific brand or they keep on changing. This study includes both high income group as well as low income group of consumers. This will help the branded companies to know that which segment is more brand conscious and which is not .The structured questionnaire helps to study the behaviour of consumers. The findings revealed that consumers are very much anxious to buy brand clothes but because of high price of branded clothes there is still very big segment who cannot buy branded clothes. So this study helps the branded companies to bring new strategies to low income group of consumers who are also potential buyers

The multilevel inverter collectively converters the several levels of dc voltage to a desired ac voltage. Multilevel inverter incorporates various pulse-width modulation Strategies.The unique structure of multilevel inverters allows them to reach nearer to sinusoidal i.e. with low harmonics. As the number of voltage levels increases, the harmonic content of the output voltage waveform decreases. The increase of voltage levels with low ratings of individual devices can increase the power rating. To produce a high-power, high-voltage inverter with multilevel structure is easy, as the device voltage stresses are controlled in the structure. The use of a high-voltage inverter makes possible. For the direct connection to the high-voltage distribution system, eliminating the distribution Transformers. An inverter can produce a controlled reactive current and operates as a Static VAR Compensation in steady state operation. The most common applications of multilevel inverters include Reactive power compensation, Back-to-Back inter-tie &Variable speed drives. The multilevel inverters are classified as Diode clamped, flying capacitor & cascaded multilevel inverters.

Indirect validation by comparison with a method suggested by other authors permits to conclude the effectiveness of the new method.

Trends, dimensions and issues relating to corporate governance are attracting the attention of academicians, industry experts, policy makers, researchers and others. As interest into the nitty-gritty of corporate governance gets intensified, the focus shifts to the emerging areas of corporate governance. Among the emerging areas of interest, the linkage between corporate governance and firm performance is fast assuming a significant place among researchers. Research on the linkage between corporate governance and firm performance has provided mixed and contradictory results and there is need to examine this linkage in the light of the Indian perspective. In this backdrop, the present paper tries to examine the linkage between corporate governance and firm performance of 30 companies of BSE Sensex by using latest available data. The paper starts with a discourse on corporate governance and a brief survey of existing literature on the issue has been carried out. Based on the guidelines available in existing literature, certain objective measures of corporate governance like proportion of independent directors, segregation of power between Chairman and CEO, presence of owner- managers, number of board meetings, pattern of institutional share holding etc. and measures of firm performance like net profit margin, return on net worth etc. have been considered. Data corresponding to these measures have been collected from reliable data sources. Regression analysis has been carried out to examine the nature of linkage between corporate governance and firm performance. The results have been analyzed and inference has been drawn accordingly.

This paper deals with the sensitivity analysis of 3-PRR planar parallel manipulators (PPMs). First, the sensitivity coefficients of the pose of the manipulator moving platform to variations in the geometric parameters and in the actuated variables are expressed algebraically. Moreover, two aggregate sensitivity indices are determined, one related to the orientation of the manipulator moving platform and another one related to its position. Then, a methodology is proposed to compare 3-PRR PPMs with regard to their dexterity, workspace size and sensitivity. Finally, the sensitivity of a 3-PRR PPM is analyzed in detail
