ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. a number of algorithms such as floating or moving cone method, floating cone method ii and the corrected forms of this method, the korobov algorithm and the corrected form of this method, dynamic programming and the lerchs and grossmann algorithm based on grap...

BACKGROUND AND AIMS Ambrosia artemisiifolia is a ruderal weed introduced from North America to Europe. It produces large amount of achenes which are highly heterogeneous in size. Due to the preponderant role of propagules in invasive plant processes, the achene mass variability related to germination, dispersal strategy and life history traits of offspring were investigated within this species....

Detection of floating-point rounding errors normally requires run-time analysis in order to be effective and software-based tools are seldom used due to the extremely high computational demands. In this paper we present a field programmable gate array (FPGA) based floating-point coprocessor which supports standard IEEE-754 arithmetic, user selectable precision and Monte Carlo Arithmetic (MCA). ...

We present a floating-point precision modeling methodology that can be used to develop application adaptive arithmetic precision models for variable bitwidth floating-point computing. We also developed optimization algorithms that minimize the total bit-width for the application such that the output accuracy meets user-defined requirements. The methodology supports different bit-widths for diff...

Due to recent technological developments, high-performance floating-point signal processing can, for the first time, be easily achieved using FPGAs. To date, virtually all FPGA-based signal processing has been implemented using fixed-point operations. This white paper describes how floating-point technology on FPGAs is not only practical now, but that processing rates of one trillion floating-p...
