类金刚石薄膜的Raman光谱分析及红外光谱特性

用酒精和氢气的混合气体为工作气体 ,在不同的酒精浓度下 (1 0 % ,1 5% ,2 0 % )下利用微波等离子体化学气相沉积法在较低温度下 (450～ 50 0℃ )以单晶硅为衬底制备出类金刚石薄膜样品。 Raman光谱分析了酒精浓度对薄膜中金刚石成份的含量的影响。红外光谱分析表明薄膜的红外光透过率与薄膜的表面形貌、薄膜结构有关。酒精浓度为 1 0 %时得到的金刚石薄膜的红外光透过率最高 ,达到 62～ 72 % ,同时透过率曲线因薄膜干涉而引起的振荡也最为显著。

基于自适应多点法的sCMOS实时非均匀性校正

为改善sCMOS读出电路工艺偏差导致的非均匀性问题,本文提出了自适应多点非均匀性校正方法。算法首先以搜寻最小范数点、阈值比较的方式分别确定最优分段点的位置以及最佳分段数量,然后再根据这些分段信息在各区间段分别进行两点校正。通过该自适应方法可有效改善传统多点法中由于分段参数选择不当导致的校正性能下降。同时,为实现实时的非均匀性校正,文中根据自适应多点法的算法特点,提出了一种与之匹配的嵌入式数据串流校正方案,可在不影响现有相机采集结构以及采集速率的情况下实现非均匀性的校正。

Preface

The vision of ''Internet as a computer'' motivates many technical trends, like pervasive computing, grid computing, service computing and recently, cloud computing, as well as some business trends, like modern service industry, digital economy and smarter planet. These evolutionary changes demand that the software systems which are running on the open and dynamic Internet have to be autonomous, context-sensitive, continuous-reactive, evolutionary, and proactive, and the software entities dispersed on distributed nodes over the Internet will be turned into self-contained, autonomous and adaptive. Thus, like the information Web, i.e. the World Wide Web, these Internet-based software entities will constitute a software Web. That gives birth a new software paradigm. A portmanteau term ''Internetware'' is used to denote the future software-web. An Internetware system will be able to perceive the changes of the open and dynamic environment, respond to the changes, and exhibit the context-aware, adaptive and trustworthy behaviors. The mission of Internetware may challenge many aspects of software technologies, from the operating platforms and the programming models to the engineering approaches. Internetware 2010, the second Asia-Pacific Symposium on Internetware, aims to provide an interactive forum where researchers and professionals from multiple disciplines and domains meet and exchange ideas to explore and address the challenges brought by Internetware. The symposium was held at Suzhou, China, during the 2-4 of Nov, 2010. Thirty three papers were submitted and each of them was reviewed by at least two members of an International Program Committee. Among them, 12 have been accepted (which means an acceptance rate of 36%) for their quality as well as for their interesting terms of discussions for the symposium attendees. This special issue contains 7 revised and substantially extended papers from the 12 based on presentations at the symposium: ......
