With the breakthrough of mobility in quantum dot electric field transistors (Q-EFTs), the potential application in these functional devices has revealed and been paid more attentions, due to flexibility in design, low cost, facility for processing and large area. One of the most important applications of FETs is the photoconductive detector. However, these functional FETs have less been reported. In this work, colloidal PbS Q-FETs were successfully fabricated by reasonable structure design and layer-by-layer depositon technique PbS quantum-dots. The bipolar property was demonstrated by the output and transfer characteristics, as devices work in I and III quadrants simultaneously. The mobilities of electron and hole are 0.16 cm2/(V⋅s) and 0.28 cm2/(V⋅s), respectively. Q-FETs work as photoconductive detectors at both positive and negative gate bias voltages. Under constant gate bias, photocurrent increase exponentially with the intensity of light. The responding region consisted with the absorption range of PbS quantum dots. A linearity was found in drain voltage and incidence of laser power, the ratio was attributing to 0.0019 (μW⋅V)-1.

An 1 MJ/0.5 MVA high-Tc SMES has been developed by the Institute of Electrical Engineering, Chinese Academy of Sciences. It has been operating in a real power grid since February 16, 2011 in Baiyin City, Gansu Province in northwest China. The SMES magnet is immersed in liquid helium and cooled by four G-M cryo-coolers to keep zero helium vaporization. To ensure safe operation of the system, protection of the HTS magnet is a necessity, which, however, cannot be complemented by only single protection. In this paper, coordinate protection of the system is introduced by an online measuring and control system and a power conversion unit, and the control principle is described in detail. By means of the coordinate protection, the temperature and pressure inside the SMES Dewar are controlled in the range of 4.3-4.5 K and 0.01~0.025 MPa, respectively. Long term demonstration of the SMES during a period of more than two years shows that the coordinate protection can ensure a stable and reliable operation of the HTS magnet.

A 360 m/10 kA high-temperature superconducting (HTS) cable has been put into demonstration operation on September 26, 2012, which is used to supply to the electrolytic aluminum workshop 10000 A. A real-time measuring and control system for the 10 kA HTS cable is developed and completed. The critical current test and data analysis are finished before the demonstration operation of the 10 kA HTS cable. The parameters of the HTS cable are monitored in demonstration operation. The inlet and outlet temperatures of the HTS cable, which are used to calculate the loss of the HTS cable, are measured accurately.

The 75 m/1.5 kA AC high-temperature superconducting cable(75 m HTS cable) and the 360 m/10 kA DC HTS power cable (10 kA HTS cable), which are supported by Chinese State 863 projects, are both of the demonstration projects facing to industrialization application. The characteristic in structure of warm dielectric (WD) insulated HTS cable is introduced. The electric field distribution characteristic at the cryogenic envelope body, the end-point of metallic shield layer at the end of the HTS cable and the connection sections are analyzed; the controlling method for electric field stress is introduced; there is serious concentration of electric field both in the termination and the connection sections between the termination and the cryogenic envelope. It is difficult to calculate the electric field of the part with irregular or special structure by resolution analytical methods, and the numerical analysis method is effective to analyze the electric field of the shaped structural part for HTS cable. The electric analysis, simulation, the design and processing of insulation for the two cables are finished based upon these two cables run well by now.

A 10 kA HTS cable for the most transmission current in the world has been successfully demonstration developed on Sep. 26, 2012 in Gongyi, Henan Province of China. The 10 kV HTS cable is 360 meters long. This paper described the temperature measuring for the 10 kA HTS cable and the calibrated error is 0.1 K. The temperature signals of the 10 kA HTS cable conclude the high-voltage temperature signals and the low-voltage temperature signals which use the different high-precision digital voltmeters to test. Software is developed by using GENESIS 64 program.

This paper introduces a novel implementation of in-vehicle traffic signs and traffic lights recognition system based on FPGA multi-core processers. Images could be processed with multi-core parallel processor using the corresponding relationships of traffic signs’ color and shape. We implement this vehicle vision system on SOPC hardware platform.

The main compression layer of Xi’an is over-consolidated. Based on the property, the physical model is designed as a steel cylinder which is 2.5m diameter,3m high. The soil layers are inter-bedded with silty clay and medium-fine sand. The consolidation pressure and overburden pressure is 295KPa. The process of soil deformation was simulated as the water recovering by increasing the water pressure in the medium-fine sand layer. Data monitoring test reveal that the deformation of the medium-fine sand layer and the silty clay layer is piecewise consequent，the consolidation will stop when the water pressure surpass a certain threshold value; During this test, the deformation of sand have the consistency with the variation of stresses in the medium-fine sand, but the deformation of the silty clay layer lagged to the variation of stress. The increase of water pressure in medium-fine sand cause compression pressure of others soil layers to increase. Based on the study of this test, we could predict that the land subsidence of Xi’an will not stop unless the confined water pressure surpasses the threshold value. What is more, we can reduce the subsidence through spasmodic pumping without cutback of pumping.
