The 4th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systemm(IEEE-NEMS) will be held in Shenzhen, China. IEEE-NEMS is a premier conference of the IEEE Nanotechnology Council to bring together world-leading researchers in the several focused topics of MEMS and Nanotechnology to disseminate their latest research results and allow cross-disciplinary exchange of knowledge to further advance both technological areas.

The exponential growth in integrated device density has yielded high-performance microprocessors containing almost 1 billion transistors per chip for the current 65 nm technology, up to now it is maybe 45nm technology. Continuous scaling of the devices and performance requires innovations in materials, processes, and designs for both back-end-of-line (BEoL) interconnects and packaging structures. Mechanical reliability has been a limiting factor for implementation of new materials and processes[1]. Electronic assemblies are the heart of all modern electronics.

Solar cells are devices that convert solar energy to electrical energy. The process in which the solar cell converts solar energy to electricity is called photovoltaic. Traditional solar cell is mostly made out of silicon, a well-known semi-conductor. When the sunlight hits the solar cell, photons from the sunlight is absorbed by the semi-conductor. The photons then hit the atoms causing electrons to be kicked out of atoms. The movement of electrons produces electricity (see figure).

功能曲面是一类具有特殊要求的曲面，它不仅要求几何形状的位置和形态精度，而且其必须满足其所要求的物理性能。在实际生产中功能曲面往往是一类复杂的自由曲面，它们不仅很难用二维图纸的方式准确表达，而且还包含了一些的物理约束和明确的物理意义。比如流曲线（stream surface）[1]，其曲面任意一点的单位切矢量和其经过的流体速度方向相同。功能曲面对产品的性能有着很大的影响, 比如发动机进气气道曲面对通过其中的气流流向和速度有很大的影响，而后者则可以直接影响到发动机中气油混合程度并决定发动机输出扭矩的大小。在实际生产实际中，采用逆向工程（reverse engineering/RE）『』的手段来重构功能曲面是一个主流的手段，因为RE方法较传统方法更加快速，灵活。整个逆向工程可以看作是一个信息的离散然后复原的过程，测量过程将目标实物离散成散乱的数据点，这是一个信息的退化过程，而重构过程就是在这些已有离散信息的基础上将原始连续的曲面信息求解出来。其中，按照通常处理的过程，又可以分为数据预处理，数据拼合，点云分割和曲面重构『』这个几个步骤。

The recognized authority for evaluating journals, Journal Citation Reports presents quantifiable statistical data that provides a systematic, objective way to evaluate the world's leading journals and their impact and influence in the global research community. In 2005, JCR Web, available via ISI Web of Knowledge, expanded its analytical capabilities beyond the journal level to include the subject category level.

 I am very honor to be a simple member of this wonderful web site,I am very earning to do something for science just before my birth,for my father is a science--sacrificing man,though he is dead now,so the rest is left to me.

I am just a college student of shangdong normal university,which is full of girls,leaving boys to be bachelors(maybe I spell it wrong).This school is very fun or funny actually.It is my third year of learning here just learning not study,for here only learning machine existing at least in my mind,I wanna study ,not just recite other man`s digest.

Multidisciplinary Design Optimization (MDO) can be defined as a formal methodology for the design of complex coupled systems in which the synergistic effects of coupling between various interacting disciplines/phenomena are explored and exploited at every stage of the design process. Why MDO?

London, United Kingdom, June 22-24, 2009, With the development of science and technology and with space exploration, hazardous environment work, and production requirements of small batch, short run and quick change-over, traditional concept of mechanisms and robots development are facing a challenge in the 21st century for adaptability and reconfigurability. Since 1990s, researchers are generating new ideas and concepts for new mechanisms and machines including robots for reconfigurability.

8-11 June 2009, Ischia Island, Italy. The objective of Coupled Problems 2009 is to present and discuss state of the art, mathematical methods, numerical methods and computational techniques for solving coupling problems of multidisciplinary character in science and engineering. Emphasis will be given on showing the potential of new computational methods for solving practical multidisciplinary problems of industrial interest.

I'm pleased to shear several websites of mechanics with mechanican, and new websites will be add continually. The names and their links are listed as following:
