Information Imbalance: A Case Study of Print Media in India

The fundamental concerns of imbalances in information and communication had been discussed for a longtime globally. The American media scholar Wilbur Schramm (1964) stated that the flow of news among nations is thin, that much attention is given to developed countries and little to less-developed ones, that important events are ignored and reality is distorted. After a long discussion and debate over media representations of the developing world in UNESCO in the late 1970s and early 1980s, a new term was coined as ‘the New World Information and Communication Order (NWICO or NWIO).’ The term was widely used by the MacBride Commission, which was charged with creation of a set of recommendations to make global media representation more equitable.

Heat Source and Radiation Effects on an Unsteady MHD Free Convective Flow past a Heated Vertical Pla

In the present paper, we investigate the effects of heat source and radiation on unsteady magneto hydrodynamic free convection flow past an infinite heated vertical plate in a porous medium. The dimensionless governing equations are solved numerically using finite element method. Numerical evaluatation of the analytical results are carried out for different values of dimensionless parameters. The results are presented graphically for velocity, temperature and concentration profiles, and observed that, when the heat source and radiation parameter increases, the velocity and temperature decrease in the velocity.

Camping Tents - A House Out Of The House

You like outside, especially when you spend time and effort generally there. There's something tranquil concerning camping over night in a good looking establishing. It seems this smell of the fresh air flow. It really is this type of travel from the standard, occupied life. If you are the sort exactly who would rather go camping, subsequently camping tents are generally something you certainly will want.

DESIGN STUDY OF COOLING FIN DEVICE

In this report, basically, it has been included the analyzing of a fin of the electric water pump motor cover temperature distribution. The effect of the convective heat transfer coefficient (h) for temperature distribution when transferring heat along the fin has been analyzed. Three different ‘h’ values have been taken and temperature distributions have been taken by using the MATHCAD program. It is shown graphically the temperature distribution along the length of a fin when changing the ‘h’ value. Importance of the convective heat transfer coefficient also has been discussed. Also variation of convective heat transfer coefficient with turbulent flow and laminar flow has been discussed.

CFD Analysis of Pelton Runner
by ijsrporg 0 Comments favorite 11 Viewed Download 0 Times

This paper presents Computational Fluid Dynamics (CFD) analysis of Pelton turbine of Khimti Hydropower in Nepal. The purpose of CFD analysis is to determine torque generated by the turbine and pressure distributions in bucket for further work on fatigue analysis. The CFD analysis is carried out on model size Pelton runner reduced at 1:3.5 scale to minimize computational cost and time. The operating conditions for model size runner is selected in accordance with IEC 60193 and IEC 1116. The paper describes the methods used for CFD analysis using ANSYS CFX software. 3 buckets are used to predict the flow behavior of complete Pelton turbine. k-ε and SST turbulence model with interphase transfer method as free surface and mixture model is compared in the paper. The pressure distribution is found maximum at bucket tip and runner Pitch Circle Diameter (PCD). The torque generated by the middle bucket is replicated over time to determine total torque generated by Pelton turbine.

Zoom FFT Algorithm in Ultrasonic Blood Flow Analysis  Using MATLAB

An adequate blood supply is required for the normal functioning of all organs in the body. However this flow can be impeded due to several reasons, thrombus or clot being a major one. Detection of such clots is done with the help of an imaging technique called “DOPPLER ULTRASONOGRAPHY” by transmitting an ultrasound pulse and calculating the frequency of the received signal. If there is no clot the reception is always a homogenous signal, whereas if a certain part being sonographed has a clot the received signal shows a variance in frequency which depends upon the distance from the receiver. Hence blood clot detection in ultrasonography is based on obtaining the frequency variance and applying adaptive thresholding.In this work we propose a ZOOM FFT based technique followed by automated adaptive thresholding to detect the clot. Data files are synthesized by simulation in MATLAB. Also the entire system is developed in a Matlab environment for the system to be both simple

The media in the west (really propaganda outlets) do all they can to villify Russia.  They must stop the free flow of information if they want to manipulate us like they did our parents

The media in the west (really propaganda outlets) do all they can to villify Russia. Simply put they are not succeeding any more due to the internet and alternative media. Want proof of that? Look at the comments in any article on the US/EU/Russia/Ukraine issues. You will see many if not the majority of people defending Russia and Putin.
