Cavity resonators are promising resources for quantum technology, while native nonlinear interactions cavities typically too weak to provide the level of control required deliver complex targeted operations. Here we investigate a scheme engineer target Hamiltonian photonic using ancilla qubits. By off resonantly driving dispersively coupled qubits, develop an optimized approach engineering arbi...

Fetal Heart Rate signal is an objective index which reflects the physiological activity of foetus heart electricity, The abstraction and processing of the signal of foetus' rhythm of the heart enclose the key technology which the foetus guards in childbirth period. For dealing with this kind of nonsteady random signal of foetus' rhythm of the heart. Through adjusting weight value the adaptive f...

As the Internet spreads widely, it has become easier for companies to obtain and utilize valuable information on their customers. Nevertheless, many of them have difficulty in using the information effectively because of the huge amount of data from their customers that must to be analyzed. In addition, the data usually contains much noise due to anonymity of the Internet. Consequently, extract...

We present an experimental technique that permits mechanical-noise-free, cavity-enhanced frequency measurements of an atomic transition and its hyperfine structure. We employ the 532-nm frequency-doubled output from a Nd:YAG laser and an iodine vapor cell. The cell is placed in a folded ring cavity (FRC) with counterpropagating pump and probe beams. The FRC is locked with the Pound-Drever-Hall ...

In this paper, an ultra-wideband (UWB) common gate low-noise amplifier (LNA) with gm-boosted and noise-cancelling techniques is presented. In this scheme we utilize gm-boosted stage for cancelling the noise of matching device. The bandwidth extension and flat gain are achieved by using of series and shunt peaking techniques. Simulated in .13 um Cmos technology, the proposed LNA achieved 2.38-3....

Engine is the main source of vibration that generates unwanted noise and vehicle chassis. Especially, in submarine applications, radiation signatures can be detected at some distance away from using a sonar array. Thus quiet operation crucial for submarine’s survivability. This study addresses reduction force transmissibility originating engines transmitted to hull through engine mounts. An ine...

Numerous factors have been proposed to explain the home advantage in sport. Several authors have suggested that a partisan home crowd enhances home advantage and that this is at least in part a consequence of their influence on officiating. However, while experimental studies examining this phenomenon have high levels of internal validity (since only the "crowd noise" intervention is allowed to...
