燃料添加剂对柴油机烟粒燃烧的影响

考察了燃料添加剂对降低柴油机烟粒燃点温度的效应。含金属添加剂的柴油机烟粒被收集在金属纤维过滤器上,把原状烟粒样品移入实验室反应器,用模拟柴油机排气进行燃烧试验。实验结果表明,当烟粒中含有Pd或Cu时,烟粒的燃点温度可降至430℃左右(普通柴油机烟粒的燃点温度约600℃);Pd的添加还可大大降低烟粒一次燃烧产物中CO的分率。文中还对金属(催化剂)/烟粒接触程度和添加剂溶液中可燃性部分对烟粒燃烧的影响作了讨论。     

利用DA算法实现大规模FIR滤波器

分布式算法是一种广泛地应用在可编程逻辑序列（FPCA）和ASIC设计中计算乘积和的算法。DA算法的处理速度仅与输入的位宽有关，对于大规模乘积和的运算，其计算速度有着明显的优势。当输入位宽过大时，可以将DA算法改进成并串结构以获得更快的处理速度。该文对在FPCA中利用DA算法实现大规模FIR滤波器，提出了具体的实现方案。

Functional magnetic resonance imaging of amphetamine craving

The aim of this study is to identify the brain activity associated with amphetamine craving for understanding the neurobiology of addiction by watching pictures of happy, sad or amphetamine. Brain activity was measured in 12 amphetamine addicts and 12 healthy subjects by fMRI while the subjects watched pictures designed to elicit happy feelings, sad feelings, or the desire to use amphetamine. The result demonstrated that amphetamine cues led to abnormally high cingulate and low frontal lobe activation in amphetamine addicts, who showed abnormalities in affect-related brain activation.

Estimation and testing of time-varying coefficient regression models in the presence of linear restrictions

A linear regression model with random walk coefficients is extended to allow for linear restrictions between the coefficients to be satisfied at each point in time. Estimation in this model is shown to be no more involved than estimation in the standard model. It is also demonstrated how, after a slight modification to the testing problem, classical test procedures may be applied to the problem of testing for such restrictions. The performance of the Lagrange Multiplier test for a variety of different restrictions is then investigated via simulation. An empirical application involving testing for homogeneity in a random walk coefficient version of the AIDS model is given.
