By moving a commercial 2D LiDAR, 3D maps of the environment can be built, based on data LiDAR and its movements. Compared to is more economical. A series problems need solved in order for perform better, among them, improving accuracy real-time performance. In solve these problems, estimating movements identifying removing objects environment, are issues that should studied. More specifically, ...

a novel low noise trans-impedance amplifier is proposed using low cost 0.18 µm cmos technology. a resistive-capacitive feedback is used to extend the bandwidth of the amplifier. as the structure is inductor less, it is suitable for low cost integrated optical interconnects. in this paper improved particle swarm optimization have applied to determine optimal trans-resistance and noise of propose...

introduction: internet searches suggest people need to check the appropriate and correct information in the field of health. meanwhile, due to the rapid growth of new technologies such as mobile technology, which today is universally accessible to all members of society, has been created a new  and  appropriate channel to offer health services that use this technology to propose best value tail...
