On Hardware Implementation of Radix 3 and Radix 5 FFT Kernels for LTE systems

Abstract in UndeterminedThis paper treats the hardware architecture andimplementation of mixed radix FFTs with cores of radix 3 andradix 5 in addition to the standard radix 2 core. The implementationflow graphs of the higher radix cores are presentedtogether with a description of how these cores afTect a pipelinedFFT implementation. It is shown that the mixed radix FFT ismore expensive than the ra

Hyperelastic constants from a modified hardness test using energy balance obtained from FE-analysis

Manufacturing test specimens, testing them in the laboratory and evaluat- ing material parameters for finite element analysis is costly and time consum- ing. In order to simplify the hyperelastic characterisation of rubber materials an extension of the standard hardness test is here proposed. A number of indentation depths are chosen for the hardness test and the indentation forces for these depth

Sprays thermometry using two color LIF and SLIPI

Knowing the droplets temperature is of great importance in spray-assisted combustion devices as it directly affects the droplet evaporation rate. This information helps optimizing the fuel/air mixture formation for the improvement of combustion devices. To measure the temperature of spray droplets, optical techniques such as Rainbow-Refractrometry (for point-wise) and the two-color LIF ratio therm
