Data Quality Guarantee for Credible Caching Device Selection in Mobile Crowdsensing Systems
With the rapid development of online social networking services, the recommendation systems are facing new challenges in recommending resources to a target group of users. How to make a trade-off between group's preference and influencer's impact is one of important problems, especially in the group recommendation on learning resources. In this paper, we propose a User Topic Influence (UTI) model, which fully exploits user topic influence together with group's preference and item content for gro

硬脆材料，如玻璃、蓝宝石等，是用途广泛的材料，具有其他材料所不具备的独特性能。从物理性能来看，玻璃表面坚硬，防刮耐磨，因此，玻璃或者强化玻璃用来制作智能手机的显示屏，蓝宝石可以用来做摄像头的保护镜、手表表面和手机指纹识别模块的盖板等，还适合用于半导体和LED 的衬底；玻璃的化学性质稳定，可用来制作电子零部件和电路基板；玻璃是电气绝缘体，且透明，也可以用来做传感器的封装和窗口。
Using CO laser light incident on an InSb crystal at 12 K, we measured the output intensity from the crystal, and the nonlinear index n2 can be determined in accordance with the transmissivity curve.
