Computer Graphics and Geometric Modellingtter. The experience and the real measure are still indispensable tools for the validation of the simulation results and its improvement..Our work consists of real experience of satellite transmission/reception. The experience was done in the national society of radio and television, where we measur

Computer Graphics and Geometric ModellingFR4 epoxy dielectric substrate. The global dimension of the proposed antenna is 24 × 14 × 0.8 mm.. We inserted a split ring in the radiating patch in order to reject the band 5–6 GHz to avoid interferences with other applications working in the same band..To study the performance of this antenna and

Computer Graphics and Geometric Modellinge mm-wave signal is produced using Impulse Radio Multiband On-Off Keying (IR-MBOOK) architecture. Then, we use an external modulator to modulate the optical signal that propagates to the Base Station (BS) through the optical fiber. This system is proposed as a solution to deal with the demands of mu

The frequency bands used are GSM, DCS and LTE-Wimax. The distance varies from the near field zone to the far field zone. The errors induced by the human body have been evaluated. Th

Computer Graphics and Geometric Modelling images. This method has gone through a large number of changes and adjustments in different types of applications. This paper reviews various LBP methods for facial expression analysis and proposes a new set of variants. Firstly, the principle of LBP is presented and the main variants for face reco
