36202.全球静态座椅市场报告(2014-2018年)
[信息传输、软件和信息技术服务业,仪器仪表制造业,其他制造业] [2014-08-28]
A seating system provides postural support for people. Following are the three categories of customer seating systems:A seating system plays a significant role in providing comfort to passengers during travel. Seating systems used in various user segments, including Passenger Vehicles and Commercial Vehicles, differ because of the varying needs of the respective user segments. These varying needs have prompted seat manufacturers to develop new concepts and technologies for specific types of automotive seats. In recent years, seating systems have progressed from providing only seating arrangements to offering extra comfort to passengers by adding more space, convenience, and value to the complete vehicle interior system.

[水利、环境和公共设施管理业,信息传输、软件和信息技术服务业] [2014-08-28]
The resolutions of interests in atmospheric simulations require prohibitively large computational resources. Adaptive mesh refinement (AMR) tries to mitigate this problem by putting high resolution in crucial areas of the domain. We investigate the performance of a tree-based AMR algorithm for the high order discontinuous Galerkin method on quadrilateral grids with non- conforming elements. We perform a detailed analysis of the cost of AMR by comparing this to uniform reference simulations of two standard atmospheric test cases: density current and rising thermal bubble. The analysis shows up to 15 times speed-up of the AMR simulations with the cost of mesh adaptation below 1of the total runtime. We pay particular attention to the implicit-explicit (IMEX) time integration methods and show that the ARK2 method is more robust with respect to dynamically adapting meshes than BDF2. Preliminary analysis of preconditioning reveals that it can be an important factor in the AMR overhead. The compiler optimizations provide signi cant runtime reduction and positively a ect the e ectiveness of AMR allowing for speed-ups greater than it would follow from the simple performance model.

36204.长脉冲激光探测大气的影响和测距(LIDAR)系统
[信息传输、软件和信息技术服务业,计算机、通信和其他电子设备制造业] [2014-08-28]
For conventional imaging systems, GEO space objects cannot be resolved due to their 40 Mm distance. There exists a strong need to obtain high resolution images of GEO objects and to accomplish this task, investigation into the suitability of ISAL is currently underway. A critical component in determining this suitability is to accurately model the atmospheric impacts on LADAR pulses. Conventional knowledge says that while the atmosphere churns, wind is the predominant cause of temporal evolution which simplifies all modeling and simulation into the frozen flow hypothesis. The concern is that the frozen flow hypothesis based phase screen generation techniques fail to accurately predict the temporal development of optical phase. This thesis proposes a new approach and provides a detailed derivation of a new temporally evolving Zernike polynomial based atmospheric phase screen generation model. This new model is experimentally verified, and utilized to analyze atmospheric impacts on mixing efficiencies. It is shown that this new turbulent flow model more accurately predicts mixing efficiency than that of the basic frozen flow approximation.

36206.全球离网型遥感电力系统市场报告(2014-2018年)
[信息传输、软件和信息技术服务业,电力、热力、燃气及水生产和供应业] [2014-08-28]
Growing energy demand is one of the primary causes for the increased reliance on off-grid power systems as the energy generated by on-grid power systems is not sufficient to fuel the market demand for power. Remote sensing systems, including applications such as LIDAR, SCADA, and various remote monitoring systems that use telemetry, are increasingly using off-grid power devices such as fuel cells, batteries, and alternative energy to power their systems. Endusers of this market include the Oil and Gas industry, Wind industry, and Weather Stations and Monitoring Sites. Off-grid power systems help to provide long-term and stable power supplies for remote sensing devices. An increase in demand for off-grid power systems is driving vendors to opt for alternative fuel sources such as fuel cells and advanced batteries.

36207.主成分算法AIRS在WRF4DVAR系统的直接同化应用
[信息传输、软件和信息技术服务业] [2014-08-28]
The use of Principal Component (PC) algorithm is explored for the efficient representation observations from high-resolution infrared sounders for the purposes of data assimilation into numerical weather prediction (NWP) models.A new version of the fast radiative transfer model has been developed that exploits principal component analysis and then implemented into the WRF 4D-Var data assimilation system,thus allow the investigation of the direct assimilation of PC scores from Atmospheric Infrared Sounder (AIRS).Testing of a prototype system where 119 AIRS spectra replaced by only 20 PC scores show significant computational saving with no detectable loss of skill in the resulting analyses or forecasts.The methodologies implemented in this regard are examined and the potential for future increased use of the data are explored.

This report presents a set of functions, written in C++, that can be used to calculate atmospheric conditions (temperature, pressure, air density, and speed of sound), as well as gravitational-field strength. The functions are based on the atmospheric model presented in U.S. Standard Atmosphere, 1976 (National Aeronautics and Space Administration. U.S. Standard Atmosphere, 1976; NASA-TM-X-74335; U.S. Government Printing Office: Washington, DC, October 1976).
