The purpose of this book is to help anyone involved in small-scale geophys- ical surveys. It is not a textbook in the traditional sense, in that it is designed for use in the field and concerns itself with practical matters – with the- ory taking second place. Where theory determines field practice, it is stated, not developed or justified. For example, no attempt is made to explain why four-electrode resistivity works where two-electrode surveys do not.

The large-scale deployment of the smart grid (SG) paradigm could play a strategic role in supporting the evolution of conventional electrical grids toward active, flexible and self- healing web energy networks composed of distributed and cooperative energy resources. From a conceptual point of view, the SG is the convergence of information and operational technologies applied to the electric grid, providing sustainable options to customers and improved security. Advances in research on SGs could increase the efficiency of modern electrical power systems by: (i) supporting the massive penetration of small-scale distributed and dispersed generators; (ii) facilitating the integration of pervasive synchronized metering systems; (iii) improving the interaction and cooperation between the network components; and (iv) allowing the wider deployment of self-healing and proactive control/protection paradigms.

Design for manufacturability and statistical design encompass a number of activities and areas of study spanning the integrated circuit design and manufacturing worlds. In the early days of the planar integrated circuit, it was typical for a handful of practitioners working on a particular design to have a fairly complete understanding of the manufacturing process, the resulting semiconductor active and passive devices, as well as the resulting circuit - often composed of as few as tens of devices. With the success of semiconductor scaling, predicted and - to a certain extent even driven - by Moore’s law, and the vastly increased complexity of modern nano-meter scale processes and the billion-device circuits they allow, there came a necessary separation between the various disciplines.

This paper presents a new type of electromagnetic damper with rotating inertial mass that has been devel oped to control the vibrations of structures subjected to earthquakes. The electromagnetic inertial mass damper (EIMD) consists of a ball screw that converts axial oscillation of the rod end into rotational motion of the internal flflywheel and an electric generator that is turned by the rotation of the inner rod. The EIMD is able to generate a large inertial force created by the rotating flflywheel and a variable damping force devel oped by the electric generator. Device performance tests of reduced-scale and full-scale EIMDs were under taken to verify the basic characteristics of the damper and the validity of the derived theoretical formulae. Shaking table tests of a three-story structure with EIMDs and earthquake response analyses of a building with EIMDs were conducted to demonstrate the seismic response control performance of the EIMD. The EIMD is able to reduce story drifts as well as accelerations and surpasses conventional types of dampers in reducing acceleration responses.

实验教学一直是工科教学中不可或缺的组成部分,对培养学生的动手能力,独立思考能力,创新思维与发散思维具有重要的作用。针对目前电路教学实验中电路仿真实验与实物电路实验各自独立,无法统一问题,提出将仿真电路实验与实物电路实验有机的结合同步操作,并使用Web发布实现远程实验操作。采用Multisim作为电路实验仿真平台,NI Eiviss II作为实物电路实验硬件平台,运用LabVIEW整合Multisim电路仿真实验与实物电路实验,实现仿真与实物实验有机结合,两种实验可同步进行。学生在仿真实验中先可探索实验,然后做实物实验。同时运用LabVIEW开发出实验过程人机交互操作接口界面,使用过程中效果良好。Experimental teaching has always been an indispensable part of engineering education.And it always plays an important role in cultivating students'practical ability,independent thinking ability,innovative thinking and divergent thinking.But simulation experiment and physical experiment cannot be unified in the circuit teaching experiment at present.In order to solve this problem,this paper proposes to combine organically the simulation circuit experiment with physical circuit experiment,and synchronously operate them.This paper uses the WEB publishing to achieve remote experimental operation.Multisim is used as the circuit simulation platform,and NI Eiviss II is used as the physical circuit hardware platform.Multisim circuit simulation experiment and physical circuit experiment are implemented by LabVIEW to realize the combination of simulation experiment and physical experiment.Students do explore experiments in simulation experiment firstly,and then do physical experiment.And this paper uses LabVIEW to develop the experimental man-machine interface.

随着数字信号处理技术和数字电路工作速度的提高,以及对于系统灵敏度等要求的不断提高,对于高速、高精度的ADC、DAC的指标都提出了很高的要求。比如在移动通信、图像采集等应用领域中,一方面要求ADC有比较高的采样率以采集高带宽的输入信号,另一方面又要有比较高的位数以分辨细微的变化。因此,保证ADC/DAC在高速采样情况下的精度是一个很关键的问题。ADC/DAC芯片的性能测试是由芯片生产厂家完成的,需要借助昂贵的半导体测试仪器,但是对于板级和系统级的设计人员来说,更重要的是如何验证芯片在板级或系统级应用上的真正性能指标。ADC的主要参数ADC的主要指标分为静态指标和动态指标2大类。静态指标主要有:Differ ential Non-Li nearity(DNL)ntegral Non-Li nearity(INL)Of fset Error ull Scale Gain Error动态指标主要有:
