The electromechanical integration design of in-piece tackling system based on the concept of generalized mechanisms is introduced. The design of the dividing equipment, the design of micro.feeding machine equipped with micro-level pressure sensor, and the realizing of computer path for patch snatching are investigated.     

试析《孙行者》中的阿新形象

阿新是美国著名华裔女作家汤亭亭的小说《孙行者》中的主人公。阿新这一反传统的华裔形象融合了中美两种文化的特征，在确认自身的美国人身份时，他对美国主流社会对东方文化和东方人存在的偏见与排斥提出了质疑。但是，作者塑造阿新形象的意图不在于彰显中美文化间的对立与冲突，暴露矛盾进而解决矛盾，最终实现两种文化的史融与平等共处才是作者的愿望。

紧凑型地波超视距雷达海杂波区目标检测影响因素研究

针对紧凑型地波超视距雷达海杂波周边及区域内目标难以检测问题，通过相关影响因素的理论及实测数据统计分析，对系统信号积累时间选取、目标航行状态与海杂波区的关联以及实测数据的联合域展开研究,分析结果为雷达相干积累时间的选取制定了取值范围。研究表明海杂波区内远距离非机动目标潜在驻留时间超过雷达积累时间，且导致的回波多普勒变化量有限，但海杂波和目标在时空及极化域具有相对较大的差异，可作为海杂波区目标检测的重要依据。     

What is mechanistic evidence,and why do we need it for evidence-based policy?

It has recently been argued that successful evidence-based policy should rely on two kinds of evidence: statistical and mechanistic. The former is held to be evidence that a policy brings about the desired outcome, and the latter concerns how it does so. Although agreeing with the spirit of this proposal, we argue that the underlying conception of mechanistic evidence as evidence that is different in kind from correlational, difference-making or statistical evidence, does not correctly capture the role that information about mechanisms should play in evidence-based policy. We offer an alternative account of mechanistic evidence as information concerning the causal pathway connecting the policy intervention to its outcome. Not only can this be analyzed as evidence of difference-making, it is also to be found at any level and is obtainable by a broad range of methods, both experimental and observational. Using behavioral policy as an illustration, we draw the implications of this revised understanding of mechanistic evidence for debates concerning policy extrapolation, evidence hierarchies, and evidence integration.

Microstructure-based multiphysics modeling for semiconductor integration and packaging

Semiconductor technology and packaging is advancing rapidly toward system integration where the packaging is co-designed and co-manufactured along with the wafer fabrication. However, materials issues, in par- ticular the mesoscale microstructure, have to date been excluded from the integrated product design cycle of electronic packaging due to the myriad of materials used and the complex nature of the material phenomena that require a multiphysics approach to describe. In the context of the materials genome initiative, we present an overview of a series of studies that aim to establish the linkages between the material microstructure and its responses by considering the multiple perspectives of the various mul- tiphysics fields. The microstructure was predicted using thermodynamic calculations, sharp interface kinetic models, phase field, and phase field crystal modeling techniques. Based on the predicted mesoscale microstruc- ture, linear elastic mechanical analyses and electromigra- tion simulations on the ultrafine interconnects were performed. The microstructural index extracted by a method based on singular value decomposition exhibits a monotonous decrease with an increase in the interconnect size. An artificial neural network-based fitting revealed a nonlinear relationship between the microstructure index and the average yon Mises stress in the ultrafine interconnects. Future work to address the randomness of microstructure and the resulting scatter in the reliability is discussed in this study.
