    The Earth's magnetic field lines and earthquake relations
    (Amer Inst Physics, 2 Huntington Quadrangle, Ste 1No1, Melville, Ny 11747-4501 USA, 2011) Ürüşan, Ahmet Yücel; 114677
    Earthquake is one of the natural disasters and very important for human life. A lot of people die every year all over the world due to earthquakes. It is very difficult to develop early warning method for earthquakes because of it has 3000 parameters. The earthquake scientists and other people involved are very hard working about this matter. Governments allocate a significant budget for earthquakes. In this study, the earth magnetic field has been researched for early warning. The questions are any tectonic plate movement is effect of the Earth magnetic field lines or changing of the Earth magnetic field lines are effect any tectonic plate. Greater than 7 M earthquakes have been chosen in this study. And 12 years period changing graphics of the earth magnetic field lines where the chosen earthquake locals have been taken.

    The neural network in coordinate transformation
    (Amer Inst Physics, 2 Huntington Quadrangle, Ste 1No1, Melville, Ny 11747-4501 USA, 2011) Ürüşan, Ahmet Yücel; 114677
    In international literature, Coordinate operations is divided into two categories. They are coordinate conversion and coordinate transformation. Coordinates converted from coordinate system A to coordinate system B in the same datum (mean origine, scale and axis directions are same) by coordinate conversion. There are two different datum in coordinate transformation. The basis of each datum to a different coordinate reference system. In Coordinate transformation, coordinates are transformed from coordinate reference system A to coordinate referance system B. Geodetic studies based on physical measurements. Coordinate transformation needs identical points which were measured in each coordinate reference system (A and B). However it is difficult (and need a big reserved budget) to measure in some places like as top of mountain, boundry of countries and seaside. In this study, this sample problem solution was researched. The method of learning which is one of the neural network methods, was used for solution of this problem.
