Abstract: Technology forecasting methods can be applied to make sure we know the potential direction, characteristic, state and effect of technology change. A good forecast can maximize gain and minimize loss from future conditions Nowadays, many companies invest a great deal in R&D to develop competitive new products and technology. Globalization and the rate of technological change in highly competitive market mean that companies need to consider increasing the R&D budgets and ensuring the money is spent efficiently and effectively. Technology forecasting is very useful for decision making in managerial issues. It can help government manage their public agendas and budgetary constraints and for business strategic direction and prioritizing R&D projects. This paper explores the technology forecasting methods and demonstrates the use of bibliographic analysis and curve fitting with Bass diffusion and exponential models for trend forecasting of titanium dioxide photocatalyst as a case example.

Abstract: Inquire into normal foot and the foot bottom of the flatfoot pressure difference to provide a reference. Carring on footprint diagraph to 206 volunteers, is divided into normal foot according to the foot bow blank width in the footprint 157, 49 flatfoots.Adopt foot bottom pressure's distributing to test system is checked the foot bottom pressure to carry on diagraph to 2 sets.Measure medium be checked request to take off shoes and socks to tread Tai to walk as usual, take three average value, dynamic state's recording 2 sets is checked foot bottom pressure.As usual fully the contact area of heel and front forefootis bigger than flatfoot, p<0.05;As usual fully the bow contact area is smaller than flatfoot, p<0.05.As usual fully bow and front the blunt quantity that forefootis subjected to is smaller than flatfoot, p<0.05;Normal heel is hurtled Be had great capacity to flatfoot, p<0.05;Under static state and dynamic state circumstance the pressures of the forefootand the foot bow acceptance are all bigger than normal foot before the flatfoot, p<0.05.Conclusion:Flatfoot the pressure center is more intensive while hitting the ground, its foot bow and front the blunt quantity been subjected to by forefootis a little bit greatly.

Abstract: The source of water in this paper is the effluent of MBR. The pressure of nanofiltration system was monitored during the conditioning phase to check the fouling of nanofiltration membrane. The morphology and distribution of polluants on the membrane surface were examined by scanning electron microscopy (SEM), with additionalenergy dispersive spectrometer (EDS) analysis. Then analyzes the main causes of membrane fouling. And the result of SEM and EDS about membrane showed that, the major foulants of membrane include organic substances and silicon dioxide. And there may be some inorganic substances, which contained magnesium (Mg) and calcium (Ca). Thought cleaning experiments with HCl, STPP (Sodium tripolyphosphate, Na₅P₃O₁₀) + Na-DDBS (sodium dodecyl benzene sulfonate, C₆H₅(CH2)₁₂-SO₃Na) about fouled membrane, cleaning efficiency is up to 87%.

Abstract: Based on finite element analysis, the structural stress of 8×8 InSb Infrared Focal Plane Array integrating with microlens arrays dependent on indium bump sizes is systemically researched. Simulation results show that as the diameters of indium bump increase from 16μm to 38μm in step of 2μm, the maximum stress existing in InSb chip first reduces, then increases, and reaches minimum with indium bump diameter 32μm. Yet the maximum stress in the indium bump array is almost unchangeable and keeps at 16.5MPa. The maximum stress in Si readout integrated circuit almost half stress in InSb chip. Besides, the stress appearing on those regions situating just on microlens array is much smaller than its surrounding regions, and the stress distribution is uniform at contacting areas between InSb chip and indium bump.

Abstract: Three kinds of rainfall results retrieved from MWRI, TMI and AMSR-E microwave imagers were compared during development of typhoon Ma-on occurred in 2011. A cloud-radiation database for MWRI was build and then used in GPROF algorithm to retrieve rainfall rate from brightness temperatures of multiple MWRI channels. The comparative results indicated that rainfall retrieved from MWRI data showed good consistency with TMI and AMSR-E rainfall products in terms of time evolution and spatial distribution. Rainfall was positively correlated with typhoon intensity, though there was time difference between the strongest precipitation and the strongest typhoon. Radial distribution of rainfall rate suggested that about 70% rainfall was concentrated within the scope of 1.5° from typhoon center. Our study is helpful for the analysis of temporal and spatial rainfall variability from different rainfall products with time- consistency.

Abstract: The automotive industry has long industry chains, supporting links and complex-round about methods of production. This article uses SWOT analysis method to analyze in detail the current situation, characteristics and prospect of Xianyang automobile industrial clusters development. Xiangyang has the definitely advantage of new energy and the biggest seat angle adjustment of Hubei. the essay points out that promote strategy advices of automobile industrial cluster rapid development in Xiangyang includes three aspects: optimize and adjust the inner industry structure, describe a refinement of the industry chain, coordinate development of automobile industry with Wuhan, Shiyan and etc.

Abstract: Three-tank liquid level system is a more typical non-linear and delay object with strong representation and background of industry. The part or whole of many objects can be abstracted into a mathematical model of three-tank liquid level system. Research on modeling and control of the system has important theoretical significance and practical value. This article describes how to use Simulink function to establish the mechanism of three-tank liquid level system model. And at the time, an improved PID control algorithm is proposed. The results show that it has more superior performance for three-tank liquid level system simulation control compared with the traditional PID control algorithm.

Abstract: Flexible smart driving mechanism is a combination of a smart actuator and flexible elements. It is an important part of the smart structure, mainly used in precise positioning and vibration control. In such application the displacement (or thrust) output and the natural frequency of the mechanism are two important design parameters. In the paper it is presented at the first that the two technical parameters (the output and the frequency) couldn’t be designed independently. Then based on static and dynamic analysis the design method of a general flexible smart driving mechanism is given. As an application, the design of a fast steering mirror, driven by a flexible smart driving mechanism is given. To verify the result, an experimental study has been done. The consistency of theoretical and experimental result is obtained.

Abstract: InGaAlAs multiple Quantum Wells (QWs) on InP substrate were designed for the loss compensation of surface plasmon polaritons (SPPs). Quantum well material, number of the quantum well, composition and other details of the wafer were discussed. The wafer was grown on n+ InP substrate by metalorganic chemical vapor deposition. Electrical-pumped device was fabricated by conventional III-V processes and e-Beam lithography (EBL) technology. When forward voltage is added on the device, it is observed that the propagation length of long-range SPPs decreases with increasing gain coefficient and the gain of the quantum wells at 1.55μm assist the propagation of SPPs.

Abstract: Referred to the protocol specification of DeviceNet, the hardware structure was set up by analysis of the physical layer and data link layer. Then it emphasized the software implementation procedure of the communication between master and slave from the view of application layer. With the software and hardware design method, a group 2 only communication node based on DeviceNet was designed through the platform of CAN controller SJA1000. Finally both IXXAT Corporation’s DNSDT protocol analysis software and RockWell’s master device were used to test the slave node. And the experimental data is detailed to verify that this slave node can fully meet the requirements specification of DeviceNet.
