摘要：An optical readout uncooled infrared （IR） imaging detector of bimaterial cantilever array using knife-edge filter operation （KEFO） is demonstrated. The angle change of each cantilever in a focal plane array （FPA） can be simultaneously detected with a resolution of 10.5 degree. A deformation magnifying substrate-free micro-cantilever unit with multi-fold interval metaUized legs is specially designed and modeled. A FPA with 160×160 pixels is fabricated and thermal images with noise equivalent temperature difference （NETd） of 400 mK are obtained by this imaging detector.

摘要：Kirigami, the ancient Japanese paper cutting technique, has been applied to achieve high stretchability and low energy loss of designed metallic glass. despite the exploration of the underlying deformation mechanism of kirigami-inspired structures from the energy point of view, the morphable responses of the kirigami patterns and the origin of the kirigami response are yet to be fully understood. This study reveals the mechanical driven-forms of the kirigami structure with the corresponding deformation stages. Based on the beam deflection theory, the elastic buckling behavior of kirigami metallic glass is manifested and a critical force prediction model is developed. Moreover, a force concentration parameter is introduced in the rigid-plastic deformation stage, predicting the nominal ultimate force. The kirigami-inspired facture force is firstly proposed. The findings of these models are in good agreement with the experimental sizedependent kirigami responses, and expected to provide significant insights into the understanding of the deformation behavior and the design of kirigami metallic glasses.

摘要：This paper presents a design for a self-powered radio frequency identification (RFId) tag with a thin film bulk acoustic reso- nating piezoelectric power supply (PPS), which can be used for portable remote temperature monitoring. We call this system a PPS-RFId for short. The RFId systems have been found to have many applications in the internet of things (IOT) in the past decade. But semi-active RFId tags require an onboard battery which limits their applications in many fields. For these reasons, our research focuses on power sources for the RFId tags. This paper emphasizes the circuit design and simulation of PPS. In our tests, 0.283 mW was generated by PPS at 1 Hz vibration by a 650 N impact force. The results showed that the integrated PPS could supply sufficient power for the designed PPS-RFId tag. The PPS-RFId tag can be widely used for temperature monitoring during mobile transport of perishable items such as medicines or food.

摘要：Recent advances in broadband technology have caused forwarding engines to handle pack- ets with over 10 gigabit per second. In this paper, we present a high-speed forwarding pipeline which can finish all of the routing and forwarding tasks in the way of pipelining. We also establish the analysis model of the pipeline with which one can evaluate some key performance parameters of the forwarding engine such as forwarding rate and forwarding delay. We find that the pipeline is of good scalability and can forward unicast packets up to the speed of 40Gbit/s.

摘要：提出相分离冷凝管在管内悬空布置微米级金属丝网,形成"气贴近管壁,液在中心"的流动结构,在管壁形成超薄液膜,显著提高管内冷凝换热系数.然而,相分离冷凝管内气泡向丝网中的泄漏,可能影响冷凝传热强化.为避免气泡泄漏,本文基于杨-拉普拉斯方程,通过考虑惯性力、黏性力及冷凝管内特有的脉动流等因素,提出相分离管内气泡泄漏的理论判别式,发现气泡泄漏主要取决于无量纲参数G*与We数;利用VOF方法发展了相分离结构中两相层流流动的数值模型.对气泡泄漏现象进行数值分析,结果表明,气泡泄漏出现在气泡顶端,与实验吻合良好;通过对比不同G*与We数下气泡运动规律,获得了气泡泄漏临界曲线,确定了气泡泄漏理论判别式中的待定参数,最终给出垂直相分离管内气泡泄漏临界判别表达式,为相分离冷凝管的设计及运行提供了理论依据.
