Cavitating flows are highly complicated because it is a rapid phase change phenomenon, which often occurs in the high-speed or rotating fluid machineries. It is well known that the cavitating flows rise up the vibration, the noise and the erosion. Therefore, the research on the cavitating flows is of great interest. Numerical method is highly important approach for studying the cavitating flow. The propeller is the predominant propulsion device used in ships. The performance of propeller is conventionally represented in terms of non-dimensional coefficients, i.e., thrust coefficient (KT), torque coefficient (KQ) and efficiency and their variation with advance coefficients (J). It is difficult to determine the characteristics of a full-size propeller in open water by varying the speed of the advance and the revolution rate over a range and measuring the thrust and torque of the propeller. Therefore, recourse is made to experiments with models of the propeller and the ship in which the thrust and torque of the model propeller can be conveniently measured over a range of speed of advance and revolution rate. Experiments are very expensive and time consuming, so the present paper deals with a complete computational solution for the flow using STAR-CCM+ software. When the operating pressure was lowered below the vapor pressure of surrounding liquid it simulates cavitating condition. In the present work, STAR-CCM+ software is also used to solve advanced phenomena like cavitation of propeller. The simulation results of cavitation and open water characteristics of propeller are compared with experimental predictions, as obtained from literature [1].

This is research paper is based on organizational stressors are also called as job related stressors. Some of the important job related causes of stress are as follows Role conflict, Role ambiguity, Organizational structure, Working conditions, Rotating shifts, Work overload, Work under load , Lack of participation in Decision making, Organizational leadership, Poor performance of the organization. The stress can have effect on the individual, the group, organization and even the family members. The degree of effect depends upon: Duration – The length of period of stress, Strength - The degree of stress, Individual Characteristics – Physical and psychological features to cope up with stress. Normally, prolonged exposure to stressful produces serious physical, psychological and behavioral effects. The effects of stress are as follows: Effects on physical health, Psychological health, and Alcoholism and drug addiction, Burnout, Effect of stress on organization behavior.

The proposed work gives a method of cancer diagnosis using artificial intelligence. The method involves the use of MRI images which are processed and segmented before the display of the tumor portion. The tumor portion will be having a denser background as compared to the general image; this has been set up in our algorithm. Some image enhancement and noise reductions are done to enhance the image quality, after that some morphological operations are applied to detect the tumor in the image.

A primarily diagnostic tool for cardiovascular diseases ECG , a non invasive technique generally used during acquisition and transportation. Noises like channel noise, baseline wander noise, muscle artifacts, electrode motion, often embedded with ECG signal. In this paper a methology to overcome from channel noise embedded during the transportation of ECG signal, proposed in this methodology DFT of noisy ECG signal calculated using fast fourier transform (FFT) algorithm. The experimental result demonstrate the proposed method is superior to other with higher SNR and lower RMSE factor, performance comparison at 1.25 dB is demonstrated. Keyword: ECG, Channel noise, Gaussian function, FFT, Wavelet transform, S-Transform.

It is been a long “Time” ,it is usually the most story’s of fairy tales started and also the second most important word is “ago” all these words which give as implication of past are related to Time, in our teachings, we learn History a lot, we learn about Mohan-ja-dare, but never seen its site, don’t we known that it is the most important part of Indus Valley civilization. In the coming years, we may not be able to see it’ ,learn about it & understand the first architecture of sanitation and hygiene gifted by our own dynastic people, therefore we must protect these site’s & try to teach more about them as these site are aspiration for young Indians to make economic cost technology for future. In the coming of ages the problem remained how to remember things and also how to preserve ,make available to our coming generations at last. Hence forth we require more wide ,simple approach to understand this. We propose a need for augmentation, we call it as augmented room .In this paper we have studied conceptual of Augmentation and observed that how Augmentation “a mixed real-virtual environment technology” will help us reach our goal. Our major aim is to prevent these monuments for our future generations so that next generation will learn and live with it. Making it possible through augmented room. This paper gives introduction to new kind of perseverance of heritage site and new transit to technology.

This study examined the relationships between strategic business model, operational plans and big picture and strategic planning process among Libyan students in Malaysia. Data was collected from 204 respondents using structured questionnaire from the selected universities in Malaysia. The descriptive analysis revealed that, majority of the respondents were male who are mostly working in the tertiary institutions in Libya. Pearson correlation analysis using SEM have shown a significant positive and high relationship between strategic business model, operational plans and big picture and strategic planning process which means, higher strategic planning process is associated with these three concepts. In line with this finding the authors concluded that, strategic planning based on theory of Pfeiffer is applicable to Libyan universities due to significant and positive relationships between the concepts in Pfeiffer’s theory and strategic planning. Thus, the authors recommends that universities, particularly in Libyan should adopt the current approach of strategic planning in order to achieve the set objectives of their universities. Moreover, if this approach is implemented in the universities by the management, it will enhance in managing information and monitoring academic development.
