32381.具有时间延迟变量的非线性程序的传感器故障检测与估计
[计算机、通信和其他电子设备制造业] [2014-06-26]
Time-delayed variables is of potentially critical impact on product quality within the processes of Metallurgical industry,Aviation industry and Chemical industry.It is very important to detect the sensor fault and estimate the values of time-delayed variables immediately as soon as faults occurred.Any fault of the time-delayed variable implies that a detrimental effect on the process will go unnoticed until the next sample become available.During this time,of course,poor quality product continues to be manufactured,a situation which is clearly unacceptable from a cost-effectiveness point of view.For nonlinear process with time-delayed variables,kernel partial least squares is introduced to monitor and estimate the fault of the Tennessee Eastman benchmark.Simulation results demonstrate the effectiveness of the proposed algorithm.

32382.使用RGB-D传感器的便携浸入式手术培训系统
[计算机、通信和其他电子设备制造业] [2014-06-26]
Surgical training plays an important role in assisting residents to develop critical skills. Providing effective surgical training, however, remains as a challenging task. Existing videotaped training instructions can only show imagery from a fixed viewpoint that lacks both depth perception and interactivity. We present a new portable immersive surgical training system that is capable of acquiring and displaying high fidelity 3D reconstructions of actual surgical procedures. Our solution utilizes a set of Microsoft Kinect sensors to simultaneously recover the participants, the surgical environment, and the surgical scene itself. We then develop a space-time navigator to allow the trainees to witness and explore a prior procedure as if they were there. Preliminary feedback from residents shows that our system is much more effective than conventional videotaped system.

32383.基于非晶合金的涡流检测传感器的设计和对比试验研究
[计算机、通信和其他电子设备制造业] [2014-06-26]
After comparing the principle features of MnZn ferrite material of high permeability and amorphous alloy of FeCuNbSiB,this paper produced an improved solution to sensor performance by applying highly magnetic non-brilliant alloy of iron base to the testing windings of eddy current testing sensors and designed the two-dimensional decomposition testing circuit in terms of sensor testing signal.It ended with a comparison between new sensors and traditional ferrite winding sensors in terms of sensibility and linearity.The experiment results showed that the new eddy current sensors have much better sensibility and linearity compared with their traditional peers.

32384.基于星敏感器的捷联惯性导航系统的陀螺仪仿真
[计算机、通信和其他电子设备制造业] [2014-06-26]
In inertial navigation system,gyro is used to measure the angular velocity of carrier relative to inertial space for achieve attitude matrix updated in real time.Gyro difficult to eliminate the error,results in strapdown inertial navigation system precision decrease with time.Star sensor is a high-precision attitude measuring instrument and don't require any priori information,the attitude date can be provided by star sensor.Thus,gyro is simulated by star sensor in order to improve the precision of strapdown inertial navigation system.

32385.全球医疗IT市场报告（2014-2018年）
[计算机、通信和其他电子设备制造业,专用设备制造业] [2014-06-26]
Healthcare IT systems improve the quality and efficiency of the services delivered and reduce errors in the Healthcare industry. Despite increased investment in IT systems resulting in the high cost of healthcare services for patients, healthcare providers choose to increase their IT spending. Both Private sector and Public sector healthcare organizations are engaging in projects that depend heavily on IT. Private companies in particular are spending more on IT, and this trend is expected to continue during the forecast period. The need to maintain standard record formats and financial incentives from governments and other international welfare organizations also encourage investment in IT in the Healthcare industry.

32386.全球工业传感器市场报告（2014-2018年）
[计算机、通信和其他电子设备制造业,仪器仪表制造业] [2014-06-18]
Industrial sensors are transducers that convert a physical quantity to an electrical signal. The signals are processed through an electronic automation system and depict the physical variation or error signal of the device or instrument. Industrial sensors are of many types and are classified as proximity sensors, position or velocity sensors, temperature sensors, pressure sensors, and vibration or acceleration sensors. Proximit sensors can be mechanical, optical, inductive or capacitive in nature. Position or velocity sensors are potentiometers, encoders, tachogenerators, and LVDTs. These industrial sensors have a high degree of accuracy, reliability, range, and sensitivity, and provide better control and automation of industrial processing units.

32390.鲁棒的无线传感器网络空间范围聚集查询处理算法
[计算机、通信和其他电子设备制造业] [2014-06-15]
现有无线传感器网络环境下的空间范围聚集查询处理算法没有综合考虑节点移动、节点失效和通信链路失效等因素对查询处理的影响,导致查询成功率低和能量消耗大.本文提出了利用节点冗余保证查询处理过程鲁棒性的空间范围聚集查询处理算法RSA( Robust Spatial window aggregation query processing Algorithm),它将查询区域划分为若干个网格,沿一条路线依次收集各网格内所有节点的数据.RSA算法给出了一种自适应的网格大小设置方法和基于网格面积的网格代表节点选择策略,以减少算法的能量消耗和提高查询成功率;给出了基于目标矩形的方法以绕过不存在节点的区域,从而避免查询处理过程出现中断.仿真实验结果表明,RSA算法优于现有的IWQE算法.
