Ini ada berita bagus. Saya ambil dari official webnya Delft. Awalnya saya tau berita ini setelah baca2 di detik.com. karena berita yang di detik.com nggak bisa di copy maka saya pergi ke situsnya Delft.Berita versi detik.com dapat dilihat di URL dbawah: http://www.detiknews.com/indexfr.php?url=http://www.detiknews.com/ index.php/detik.read/tahun/2005/bulan/12/tgl/24/time/130429/idnews/ 505501/idkanal/10 Klo yang di detik.com disebutkan klo Yogi ini orang bekasi dan dosen ITB yang ngambil Ph.D di delft. Tapi setelah baca di web-nya delft, saya nggak ketemu keterangan itu. tapi walau bagaimanapun saya yakin klo Mas yogi ini pasti orang Indonesia. Kan nggak mungkin orang belanda ato orang jerman ada yang namanya Yogi. semoga berita ini bisa menjadi motivasi buat kita semua. ----------------------------------------------------------------- Delft mathematician simplifies the search for oil 23 December 2005 by M&C Press release - Mathematical research at Delft University of Technology is making it easier to look for oil. Yogi Ahmad Erlangga, who receives his doctorate on Thursday 22 December, has developed a method of calculation which enables computers to solve a crucial equation much faster. In the past, this stumped oil company computers. Funded by Shell and SenterNovem, Erlangga's research is pure mathematics. It all centres on the so-called Helmholtz equation. Solving this is important in interpreting the acoustic measurements taken when prospecting for oil. Sound waves are transmitted into the ground and their reflections recorded as they return to the earth's surface. Analysis of this data enables specialists to locate oil deposits. In the past, these measurements have been taken two-dimensionally. Effectively, the earth was surveyed as a series of flat layers. But the oil companies would rather use a faster method involving three- dimensional blocks. Until recently, though, their computers were not powerful enough to do that. Solving the Helmholtz equation requires huge arithmetical capacity. As part of his PhD research, Erlangga has succeeded in making the method of calculation used to solve the Helmholtz equation a hundred times faster. And that finally makes it possible for firms like Shell to use 3D calculations when prospecting for oil. So it seems highly likely that oil companies will express an interest in exploiting Erlangga's work. But other applications are also conceivable. This is because the Helmholtz equation is used to describe many kinds of wave. Not just acoustic ones, as in the oil example, but also electromagnetic waves including visible light. It is quite feasible, therefore, that Erlangga's work could be applied to lasers in data storage on a Blu- ray Disc, for example or to radar measurements in aviation. "Given the responses we have had from industry and foreign universities," says Dr Kees Vuik, Erlangga's PhD supervisor, "we believe that a thirty-year-old problem has been solved in this work."
