Nondestructive evaluation of pavements using spectral analysis of surface waves in the frequency wave-number domain

The potential of using Spectral analysis of surface waves (SASW) for nondestructive testing of pavement and soil sites has been demonstrated in several publications. The usual SASW field testing and data analysis procedures and the assumption of a single propagation mode yield accurate results when there are no sharp changes in the stiffness of the site with depth. When this is not the case, however, difficulties arise in the interpretation of experimental data due to the participation of more than one mode in the wave field. In an earlier study, the multiple filter/crosscorrelation technique was suggested for analyzing multi-mode SASW signals. This technique, however, may not yield accurate results when propagation modes are closely spaced. A more general method using spectral analysis in the frequency wave-number domain is presented in this paper. Formulas are presented for determining a reasonably small number of surface measurements, and the accuracy of this method in resolving experimental dispersion curves is demonstrated for a pavement site.

鄂北地区气测现场解释评价研究

鄂尔多斯盆地鄂北地区现场气测录井由于受多种因素影响,解释符合率相对较低。针对这一问题,在探讨影响气测录井显示因素、识别气测异常的基础上,分析了消除影响因素的途径和校正公式,建立了随钻全烃与全脱全烃的关系式,论述了地面和地层含气量计算方法。在初步评价气显示性质条件下,经统计分析得出了应用4参数——峰面积、校正全烃值、全烃计算值和地层含气量加权分值的解释评价标准,为鄂北地区气测录井解释评价和产能的初步预测探索了一种新模式,不但解决了鄂北地区气测解释符合率低的问题,而且对于深入开展气测录井参数与油气解释评价研究具有一定的参考意义。     

Laboratory and Field Consumer Evaluation Relationships for Menu Items Processed in Retortable Trays for Quantity Foodservice

Problems associated with provision of food in quantity foodservices prompted the development and use of prepared food items processed in retortable trays. Consumer acceptance of such foods was required so that the items could be screened for foodservice application. Consumer tests, using small portion samples and sensory testing under laboratory conditions, gave a relatively reliable prediction of acceptability of most of the items under extended-use consumer testing during a field trial. Final field acceptance of some items was influenced by external factors not accounted for in laboratory testing.
