In this study described the use of the previously Finite Difference Time Domain method, for analyze the behavior electromagnetic with a diffractor or Perfect Electric Conductor inside of an antennas circular array of 17 elements, this array consists of one transmission antenna and 16 receiving antennas RX. The system uses a Gaussian pulse as excitation with a frequency of 7.5 GHz. The method solves...
Rheological properties of solutions prepared using xanthan (XG), locust bean (LBG) or sodium carboxymethyl cellulose (CMC) gums, and their binary mixtures were studied. The influence of shear rate, total gum content, measurement time and temperature on the apparent viscosity was investigated. In the binary mixtures, the presence of different gum ratios at several total gum content was also analysed...
This paper presents a communication scheme design with VHDL language for parallel array of processors implemented in a Field Programmable Gate Array (FPGA) for the solution of linear equation systems. The solution is performed using the division-free Gaussian elimination method. This algorithm was implemented in integrated processors in a FPGA Spartan 3 of Xilinx. The communication design uses read/write...
This paper presents a parallel array of processors implemented in a Field Programmable Gate Array (FPGA) for the solution of linear equation systems. The solution is performed using the division-free Gaussian elimination method. This algorithm was implemented in integrated processors in a FPGA Spartan 3 of Xilinx. A top-down design was used. The architecture modules were designed in VHDL language...
