随着科学技术不断发展,教育教学理念和模式发生了很大改变,移动App是计算机科学技术发展到一定阶段的产物,在教育教学过程中App发挥的作用也越来越明显.本文对App在高校网络教育中的应用进行分析与探讨,旨在提高高校教育水平.
In this paper, RFID radio frequency identification technology advantages of the existence of a systematic analysis, according to the corresponding information management system designed specifically for the program, while the system considerations in the development process is carried out in-depth analysis. From the corresponding practice can be learned in terms of improving the level of laboratory information manage-ment, RFID technology has a unique role in promoting.
一直以来，各个高校的实验设备或者贵重物品都存在着可能失窃的风险，面对动辄几万甚至几十万的贵重实验设备被盗的情况，如果有一种在其将要失窃时能够自动报警的装置，那将会使损失大大的减少。目前很多高校实验设备的防盗报警还都跳不出需要有人值守的模式，即浪费了人力、又需要额外的开支，还很难实现全天候不间断监控。市场上针对这种情况也出现了一些报警设备。但良莠不齐。为了解决这一问题，本设计把TRIZ理论应用到远程控制自动报警装置中，自主创新，设计出符合高校需求并具有市场竞争力的防盗报警装置，对于高校实验设备远程防盗报警具有重要的指导意义。
An active anti-theft alarm system for vehicles is designed in this paper, which realizes real-time anti-theft alarm function . This system adopts SMS and MMS via GPRS as data transmission way by means of the wireless communication network data channels . The system not only uses the multi-sensors to monitor the conditions of vehicles but also adds the real-time image acquisition function and collects the data of the vehicle positions through GPS. Several experiments show that the system meets the demands of the real-time anti-theft alarm function for vehicles completely
The fixed pattern noise component of 3D noise model is used to detect blind-pixel of IRFPA as data source.It can be classified to dead pixel and over hot pixel by representable form of blind-pixel.As for dead pixel,the paper uses double-end dividing threshold value to detect dead pixel,which is determined by prior knowledge using quantity limited and low probability density characteristic of its hitstogram.But as for over hot pixel,it is regarded as abnormal pixel of Gaussian distribution noise,and then,detected by statistic distance threshold value that is determined by asymmetry coefficient of hitstogram removed dead pixel.The result of experiments shows that it is a practical method of blind-pixel detection.
