Impact of the shadow banking system on monetary policy in China

The shadow banking system in China has its own characteristics compared to conventional commercial banks and the foreign shadow banking system. Its emergence is important to the economic development and financial system in China. However, it also challenges the implementation of monetary policy and regulation. China is in the economic shunt period and their monetary policy system is somewhat lagging behind the advanced economic system. This paper is therefore designed to figure out the impacts of the shadow banking system on monetary policy. After analysis of SVAR model, OLS regression, trend graph and correlation coefficient, results show that an increase in the growth rate of the shadow banking system would affect the monetary policy by increasing money supply and the value of CPI. Moreover, the implementation of easy or tight monetary policy by increasing or decreasing the benchmark interest rate would not be able to achieve the original goals due to the activities of the shadow banking system. It is suggested that the Chinese authorities should follow the market requirement to improve the monetary policy system by means of supervision and regulation on the shadow banking system which would the monetary policy effect

The result showed that the separation process was completely finished at 60th second of centrifugation time. The average of separation rate was 110 g/s for the 30th second and 82.2 g/s for the 60th second of centrifugation time, with the yield of 83.3%.Keywords: Separation, Soymilk, Centrifugatio

Sectional variable frequency and voltage regulation control strategy for energy saving in beam pumping motor systems

Despite the fact that the energy losses in the beam pumping motor systems (BPMS) utilized in oil fields represent a monumental challenge industrially, very few studies discussed the feasibility and applicability of a universal energy saving technology for such industry. This study proposes a sectional control strategy integrating variable frequency (VF) with voltage regulation (VR) based on the mechanical load characteristics of the BPMS. Main merits of the proposed strategy are as follows: 1) controlling horse-head acceleration through VF, and indirectly weakening the inertia torque of polished rod load, thereby reducing the power consumption during the up-stroke; and 2) based on monitoring load conditions in real time, auto-tracking VR is adopted to optimize the online efficiency of the system. The proposed strategy utilized the adaptive fuzzy logic control to alternate between VF and VR modes. The proposed energy saving strategy was applied to a CYJ10 BPMS driven via a 37-kW induction motor in simulation and experimental environments. Results revealed that the effectiveness of the proposed strategy to improve the load balance effects through better utilization of the counterbalance during the heavy-loading conditions in up-stroke. Furthermore, the energy consumption is reduced via the auto-tracking of VR under light-loading conditions during the down-stroke. Moreover, the energy saving ratio is more than 10% under different dynamic liquid levels and counter weights. The effectiveness of the proposed strategy is verified through comparing the calculated results with the measured data for a standard oil rig, and the generality is verified as well

Determining the optimal range of coupling coefficient to suppress decline in WPTs efficiency due to increased resistance with temperature rise

The continuous operation of the wireless power transfer system (WPTS) under high-frequency switching activity might cause a temperature rise in various system\u27s components. That temperature rise might increase the resistance of the primary and secondary coils, which will lead to a significant decline in the system\u27s efficiency. To address this problem at the design stage, we investigate the optimal range of the coupling coefficient that suppresses the efficiency drop due to the increasing resistance of the WPTS components. The proposed optimal range of the coupling coefficient can also ensure the output power requirements of the WPTS. Using four different WPTSs, the determination method for the optimal range of coupling coefficients under different system operational frequencies was developed and implemented. A 3-kW resonant experimental prototype WPTS was designed and built to validate the proposed coupling coefficients experimentally. The experimental results show that the optimized coupling range successfully suppressed the efficiency decline resulting from the increasing resistance caused by temperature rise

TU-F-CAMPUS-J-03: Elasticity functions based on 4DCT images to predict tumor and normal tissue response to radiation for patients with lung cancers

Purpose: To investigate radiotherapy outcomes by incorporating 4DCT‐based physiological and tumor elasticity functions for lung cancer patients. Methods: 4DCT images were acquired from 28 lung SBRT patients before radiation treatment. Deformable image registration (DIR) was performed from the end‐inhale to the end‐exhale using a B‐Spline‐based algorithm (Elastix, an open source software package). The resultant displacement vector fields (DVFs) were used to calculate a relative Jacobian function (RV) for each patient. The computed functions in the lung and tumor regions represent lung ventilation and tumor elasticity properties, respectively. The 28 patients were divided into two groups: 16 with two‐year tumor local control (LC) and 12 with local failure (LF). The ventilation and elasticity related RV functions were calculated for each of these patients. Results: The LF patients have larger RV values than the LC patients. The mean RV value in the lung region was 1.15 (±0.67) for the LF patients, higher than 1.06 (±0.59) for the LC patients. In the tumor region, the elasticity‐related RV values are 1.2 (±0.97) and 0.86 (±0.64) for the LF and LC patients, respectively. Among the 16 LC patients, 3 have the mean RV values greater than 1.0 in the tumors. These tumors were located near the diaphragm, where the displacements are relatively large.. RV functions calculated in the tumor were better correlated with treatment outcomes than those calculated in the lung. Conclusion: The ventilation and elasticity‐related RV functions in the lung and tumor regions were calculated from 4DCT image and the resultant values showed differences between the LC and LF patients. Further investigation of the impact of the displacements on the computed RV is warranted. Results suggest that the RV images might be useful for evaluation of treatment outcome for lung cancer patients
