In the recent years, much attention has been paid to the research and development of structural control techniques with particular emphasis on alleviation of wind and seismic responses of buildings and bridges in China. Structural control in civil engineering has been developed from the concept into a workable technology and applied into practical engineering structures. The aim of this paper is to review a state of the art of researches and applications of structural control in civil engineering in China. It includes the passive control, active control, hybrid controland semiactive control. Finally, the possible future directions of structural control in civil engineering in China are presented.

Quality Control Techniques

The application of quality control theory to shipyard practices is described. The work is facilitated from the project engineering level on a contract applying a construction process which includes state-of-the-art technology employed by shipyards and other manufacturing industries throughout the world. The paper explains the benefits to be derived by using quality control methods in the production processes. The system is enhanced further when designs are configured to recognize production factors. The quality control techniques described herein have proved effective in bringing the process under control and maintaining the dimensional integrity of the subject series of vessels.

In this articles the authors present a review of non-linear structural control techniques. This is an area of growing importance in a range of engineering applications, where non-linear behaviour is encountered. Structural control is usually divided into three main areas: (a) passive (b) semi-active, and (c) active control. This article follows this convention, and highlights in each section the relevant state of the art for non-linear systems, with additional references to related linear approaches.

Metallic Contamination

ABSTRACTUltraclean semiconductor processes were developed for ULSI technologies to significantly reduce metallics, foreign materials, and to preserve silicon surface morphology. State-of-the-art detection techniques (Elymat, TXRF, VPD, and SPV) were implemented in all critical process sectors. Acceptable levels of metallic contamination were derived from previous experience and from published work on this subject relating metallic contamination levels to gate oxide reliability and retention time.A comprehensive diagnostic/characterization system was utilized in evaluating a wide variety of test structures emulating key device process interactions. Advanced techniques were employed for measurement of reliability and surface morphology. Also root causes for all integration problems are identified.

AbstractThe degree of contamination in soils, sediments and dusts can be assessed based on knowledge of a variety of factors, such as industrialization, type of contaminants, deposition conditions, contamination-control techniques, along with the characteristics of the recipient environmental compartments, which include pathways for contamination transport, depth of infiltration, and degree of groundwater contamination. The impact of contaminants also depends on the quantity, mobility and speciation of contaminants/wastes as well as on the sensitivity of the recipient compartments. With sufficient knowledge of these factors, a number of conclusions can be drawn concerning the status of contamination in industrialized areas. This literature review aims to scrutinize some of the methods used to analyse the occurrence, speciation, mobility, bioavailability and likely the toxic effects of contaminants in the environment.
