Computational fluid dynamics, usually abbreviated as CFD, is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial experimental validation of such software is performed using a wind tunnel with the final validation coming in full-scale testing, e.g. flight tests.
In finance, a contract for difference (or CFD) is a contract between two parties, typically described as “buyer” and “seller”, stipulating that the seller will pay to the buyer the difference between the current value of an asset and its value at contract time. (If the difference is negative, then the buyer pays instead to the seller.) In effect CFDs are financial derivatives that allow traders to take advantage of prices moving up (long positions) or prices moving down (short positions) on underlying financial instruments and are often used to speculate on those markets.
CFDs are currently available in the United Kingdom, Hong Kong, The Netherlands, Poland, Portugal, Germany, Switzerland, Italy, Singapore, South Africa, Australia, Canada, New Zealand, Sweden, Norway, France, Ireland, Japan and Spain. They are not permitted in the United States, due to restrictions by the U.S. Securities and Exchange Commission on over-the-counter (OTC) financial instruments.
“My Brain logic gates functions even faster than the fastest supercomputer more than a few hundred times, Yes/No, True/False, Up/Down I can handle anytime to find out any solutions, but forget asking me to calculate numbers, it is not trained for that. That is also the reason why nobody can built my computer, it is a super intelligent Neural Computer, and all the requirements are totally different, even the output is different. Everybody is living the age when they think the world is flat, but actually it is round.” – Contributed by Oogle.
