Being reversible, the original digital content can be completely restored after data extraction. Prediction-error expansion (PEE) is an important method in reversible watermarking. PEE can embed large payload with low distortion into digital images. PEE is advantageous use in image redundancy usually gives better performance. But, the correlations between prediction-errors are not regarded and not use in conventional PEE based methods. In PEE, the prediction-errors are expanded and modified individually for embedding the data.

Owing to the complexity of sampling and running environment, abnormal data such as outliers as well as patchy outliers widely appear in a variety of data from engineering to economic fields. These abnormal data have remarkable bad impact on parameter statistics, system identification, state monitoring, process control, machine learning, decision analysis, and so on. In order to avoid bad impact from abnormal data, a new idea of outlier-tolerant computation was put forward in just the past two decades.

In this paper a deterministic fuzzy inventory model for time dependent deteriorating items with lead time and stock dependent demand rate has been developed. The ordering cost, deterioration cost, holding cost and shortage cost are assumed as triangular fuzzy number. In this model shortages are allowed during the lead time and completely backlogged. An economic order quantity (EOQ) has been obtained. The derived model is illustrated by a numerical example.

The world challenge facing humanity is connected to the fourth largest disaccharide carbohydrate sugar - cane and beet, which is the only preferred sweetener connected to our daily life. Fructose declared the white poison and responsible for human metabolic imbalance, which is the established fact through many hundreds of research from the year 1970. One more challenge connected to sugar being the high glycemic index food not suitable for the huge diabetic population around the world.

The study aims to contribute to the research literature by throwing light on the relationship between Organizational Commitment of teachers in relation to their Emotional Intelligence; for the study descriptive method was applied. The study was conducted on IGNOU teachers teaching in Government and private senior secondary Schools of Arunachal Pradesh, affiliated to CBS board. Out of the total 89 secondary schools male teachers (46) and female teachers (43) were taken from the overall schools for the research work.

Conducting polyaniline/Yattrium oxide (PANI/Y2O3) composites have been synthesized by insitu deposition technique by placing fine graded Y2O3 in polymerization mixture of aniline. The PANI/ Y2O3 composites have been synthesized with various compositions viz., 10,20,30,40 and 50 wt % of Y2O3 in PANI. The ac conductivity was studied in the frequency range 102 – 106 Hz. It is observed from the ac conductivity studies that the ac conductivity is found to be constant up to 105 Hz and there after it increases steeply which is a characteristic feature of disordered materials.

Sports has a very prominent role in a modern society it is important to an individual, a group , a nation- indeed the world. The two types test balance which are in common use in physical education are test of static balance and test of dynamic balance static balance may be defined as that physical ability which enables an individual to hold a stationary position.

The purpose of this study was to estimate the CTV-PTV margin required for prostate cancer cases at the radiotherapy department of Basvatarakam Indo American Cancer Hospital and Research Institute, Hyderabad. Portal image data from patients treated at the radiotherapy departments during the period of 2013-2015 was used to estimate the set-up displacements for each prostate area. By using the acquired images the magnitude of the systematic, i.e. preparatory, and random, i.e. execution, error was determined in the anterior- posterior (AP), superior-inferior (SI) and right-left (RL) direction.

In this paper, a fuzzy logic control (FLC) is proposed for maximum power point tracking (MPPT) in wind turbine connection to Permanent Magnet Synchronous Generator (PMSG) and also a fuzzy logic controller based wind energy conversion system where total harmonic distortion is better than PI controller. A fuzzy control strategy for achieving maximum benefits from these grid-interfacing inverters when installed in single phase load connection.

The purpose of this study was to find out Investigating the Center of Percussion (COP) of Cricket Bat. To achieve the purpose of the study, cricket bat (reebok yuvi burn) was selected by the investigator. The variable selected for this study was Center of Percussion (COP). To measure the Center of Percussion (COP) accelerometer sensor was used. The collected data were statistically analyzed by the repeated measures design of ANOVA. In all the cases 0.05 level significances was fixed.
