Dissymmetric warfare versus asymmetric warfare

This paper presents two concepts: asymmetric warfare and dissymmetric warfare. NATO and US Military operations in recent wars in Kosovo and Afghanistan are analysed by means of comparison with old Chinese strategic thinking. No‐Loss‐Strategy and virtual warfare as well as the transformation from asymmetric to dissymmetric and from dissymmetric to asymmetric warfare are reflected upon.

提出的遥测心电监护系统采用蓝牙无线技术监测病人的心电等生理参数,克服了使用传统的有线系统及病人不能自由活动的缺点。系统的发射机主要由蓝牙模块ROK101007和带有8通道12位A/D转换器的微控制器ADuC812组成,ADuC812主要进行心电数据的采集和控制,两者之间通过UART接口进行指令和数据的传输。接收机通过USB接口与PC机或者笔记本电脑实现高速数据通信而不需要外加工作电源。试验表明,该系统能有效地无线传输心电数据。     

Performance updating of concrete bridges using proactive health monitoring methods

Uncertainties associated with modelling of deteriorating bridges strongly affect management decisions, such as inspection, maintenance and repair actions. These uncertainties can be reduced by the effective use of health monitoring systems, through which information regarding in situ performance can be incorporated in the management of bridges.The objectives of this paper are twofold; first, an improved chloride induced deterioration model for concrete bridges is proposed that can quantify degradation in performance soon after chlorides are deposited on the bridge, rather than when initiation of corrosion at the reinforcement level takes place. As a result, the implications of introducing proactive health monitoring can be assessed using probabilistic durability criteria. Thus, the second objective of the paper is to present a methodology for performance updating of deteriorating concrete bridges fitted with a proactive health monitoring system.This methodology is illustrated via a simple example of a typical bridge element, such as a beam or a part of a slab. The results highlight the benefits from introducing ‘smart’ technology in managing bridges subject to deterioration, and quantify the reduction in uncertainties and their subsequent effect on predictions of future bridge performance.     

Mismatches in Social Support and Psychosocial Adjustment to Breast Cancer.

Emotional support is known to provide psychosocial benefits for women with breast cancer, but women can experience a mismatch between support that is wanted and support that is received from their personal supporter. The role of wanted and unwanted support in psychosocial adjustment was examined in 79 women recovering from breast cancer. Four distinct patterns of desired support actions were found using cluster analysis. Patterns of wanted support were not related to better or worse psychosocial adjustment. However, a misalignment of support between the provider and the receiver significantly influenced psychosocial adjustment, and unwanted but received support (support commission) was uniquely associated with poor psychosocial adjustment. Clinical interventions using the support instrument could help match support providers' actions to receivers' preferences. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A Six-sigma approach for benchmarking of RP&M processes

This paper presents a methodology of using six-sigma quality tools for benchmarking of rapid prototyping & manufacturing (RP&M) processes. It involves the fabrication of a geometric benchmark part and a methodology to control and identify the best performance of the process to reduce the variablity in the fabricated parts. The approach is demonstrated with a case study based on the direct laser sintering (DLS) process for prototyping using plastic powder. In the case study an identified set of six-sigma/ statistical process control tools is employed to determine and best tune factors affecting the desired outcomes of the built parts.
