Consider detection problem for multisensor system with Gaussian measurements. According to the Neyman-Pearson criterion, the detection probability was maximized subject to an upper limit on the probability of false alarm. In this case, it is well known that the optimal test admits the likelihood-ratio test (LRT) form. However the threshold computation of LRT is generally computationally intractable...
In this paper, a novel low cost process for preparing wafer-level spherical Rb vapor cell for miniature atomic clocks is presented. The process is studied experimentally, which consists of the following steps: 1) small cavities A (for reactants) interconnected with large cavities B (working chamber) and channels are wet etched simultaneously on one side of a silicon wafer; 2) foaming agents and chemicals...
With power densities rapidly increasing in electronic devices, thermal management in microelectronic technology has become a crucial issue in maintaining the performance and reliability. Carbon nanotube (CNT) as a thermal interface material (TIM) has attracted extensive attention for its ultrahigh thermal conductivity, but not yet put into application due to its weak interfacial connect to substrate...
A glass microfluidic device integrated with ultrasonic resonators prepared by a Chemical Foaming Process is presented in this paper. The fabrication of the microfluidic device including glass micro cavities and channels with ultrasonic resonators integrated was introduced firstly. By the CFP process, micro glass cavities and channels were simultaneously shaped on a glass wafer. Then, vibration tests...
