Instead of acquiring the previous aberrations an optical wavefront with a sensor, sensor-less (WFSless) adaptive optics (AO) systems compensate for distortion by optimizing performance metric directly. The stochastic parallel gradient descent (SPGD) algorithm is pervasively adopted to achieve optimization. In this work, we incorporate CoolMomentum, method optimization Langevin dynamics simulate...

Network throughput and energy conservation are two conflicting important performance metrics for wireless sensor networks. Since these two objectives are in conflict with each other, it is difficult to achieve them simultaneously. In this paper, a joint duty cycle scheduling and energy aware routing approach is proposed based on evolutionary game theory which is called DREG. Making a trade-off ...

A micro-fabricated metal-oxide based conductometric pH sensor is designed and fabricated in this manuscript. pH sensors have applications in various areas from farming to food processing, human health monitoring, industrial waste products investigation, etc. Accordingly, there is a relatively high demand for a reliable, rapid and precise pH sensor in the market. Relatively precise pH sensors ha...

Wavefront sensing is a widely used non-interferometric, single-shot, and quantitative technique providing the spatial-phase of beam. The phase obtained by integrating measured wavefront gradient. Complex random wavefields intrinsically contain high density singular structures (optical vortices) associated with non-conservative gradients making this integration step especially delicate. Here, us...
