Abstract: This paper presents an extension of the Coordinate Modal Assurance Criterion (COMAC) for spatial comparison of mode shapes. As is the case for the original COMAC, this enhanced COMAC helps identify degrees of freedom differences between test and analysis modes, but also overcomes some of the limitations of the original COMAC. The original COMAC cannot identify errors caused by scaling or polarity mistakes in the test data. Such mistakes are easily made during modal tests and not always easily detected since they do not affect the subjective quality of a frequency response function.

Abstract: The ultra-thin gate oxide required for the 0.13 /spl mu/m generation and beyond introduces a significant amount of gate-to-body tunneling current. The gate current modulates the body voltage and therefore the history effect. This paper discusses several methods to minimize the impact of gate current, which can cause excessive history effect in 0.10 /spl mu/m SOI CMOS. Our result demonstrates that the combination of high gate leakage and small junction capacitance can enhance circuit performance due to beneficial gate coupling. Ultra-low junction capacitance can be achieved by aggressive SOI thickness scaling, though, the proximity of source/drain extension and channel depletion to the buried oxide complicates device design and modeling.

Abstract: Background: To implement effective behaviour change interventions for men who have sex with men, qualitative information was collected about the contexts and meanings of sex and relationships between men in Ho Chi Minh City. Methods: Individual interviews and focus groups were conducted with 74 men aged 18 years or older who had had sex with another man in the previous 12 months. Results: Findings reveal that sex between men exists and is associated with two common descriptors in Vietnam: bong lo for those who are feminised in public and bong kin for those who are not, and are often married. In sexual relationships, for both groups of men, there is a trade off between sexual pleasure and risk. Condoms may not be used, particularly when having sex with a partner who was considered to be good looking or perceived as ‘clean’. Conclusions: The study highlights the need for HIV prevention programs which address issues of sexual meaning in male-to-male sexual relationships.

Abstract: As America refocuses its attention on the factory, design and manufacturing engineers must work together closely to design the appropriate products, and matching production process in a team effort. By building off the designer's CAE tools that predict product performance, the manufacturing engineer is today able to simulate the proposed production process. Process simulations for the following manufacturing processes are available or being developed: ▪Forging, ▪Machining, ▪Injection Molding, ▪Die Casting, ▪Investment Casting, ▪Metal Forming, ▪Heat Treating, ▪Assembly Tolerancing By utilizing the same 3-D solid model and finite element modeling tools used by the designer, coupled to powerful analysis simulation tools to predict the transient nonlinear heat transfer and plastic material flow found in many manufacturing processes, the manufacturing engineer is able to explore alternative processing plans, evaluate trade-offs and even influence the design to produce superior products.
