Density Current is formed when a fluid with heavier density than the surrounding fluid flows down an inclined bed. These types of flows are common in nature and can be produced by; salinity, temperature inhomogeneities, or suspended particles of silt and clay. Driven by the density difference between inflow and clear water in reservoirs, density current plunges clear water and moves towards a d...

We present an imaging method that creates a map of reflection coefficients in correct one-way time with no contamination from internal multiples using purely a filtering approach. The filter is computed from the measured reflection response and does not require a background model. We demonstrate that the filter is a focusing wavefield that focuses inside a layered medium and removes all interna...

ramadan fasting during the month of ramadan is a religious obligation, practiced by millions of people around the world. ramadan fasting is essentially a fundamental change in lifestyle for one lunar month. this type of fasting may have significant effects on lipid profile. although there is no scientific consensus about the effects of fasting on cardiovascular risks such as changes in lipid pr...

Article history: Received 8 August 2012 Received in revised form 20 September 2012 Accepted 9 October 2012 Available online 3 November 2012 Many of the meteorological phenomena occurring at meso-γ require observations sufficiently close together in time and space. The multichannel microwave radiometer (MMWR) provides continuous temperature and humidity profiles. We demonstrate a method for prof...

soil compaction can occur as a result of a number of factors. one of the most important factors is soil response to pressures imposed by wheels and soil engaging tools. this research investigated the effect of tyre load and inflation pressure on soil compaction-related factors. these factors include rut width, rut depth, cone index and horizontal force in different layers of soil profile. in th...

In order to improve accuracy and convergence speed for flight trajectory optimization program in flight management computer and enhance its maintainability, an improved particle swarm optimization (PSO) algorithm with object-oriented performance database is proposed. Firstly, an object-oriented performance database is built by Microsoft Visual C++ and MATLAB/SIMULINK mixed software development ...

In order to study the wakefield effects of an electron cloud, a test bunch was placed behind a bunch train, where the cloud density rapidly varied. A currentdependent tune shift and the tune spread of the test bunch were measured as a function of the bunch current while varying the bucket position of the test bunch. The vertical tune shift indicated a strong defocusing force together with a wid...
