Fouling propensities of blended coals in pulverized coal-fired power station boilers

This paper presents the experimental results on the fouling propensity of five pairs of blended coals (19 coals and blends) tested in the Australian Coal Industry Research Laboratory (ACIRL) furnace. The results showed that the coal D has the highest fouling propensity among tested coals and blends. A parameter, growth rate (mm/h), is used to numerically rank the fouling propensity based on photos of fouling deposits taken over a period of test time. The growth rate correlates the fouling propensity better than the build up rate or the fouling coefficient. Five empirical fouling indices are examined against the fouling propensities of the above 19 coals and blends, and another 10 coals and blends previously tested in the Energy and Environmental Research Cooperation (EER) furnace. The linear correlation between the flue gas exit temperature/initial deformation temperature (FGET/IDT(ox.)), a measure of the overall heat transfer in the furnace, and the Na₂O, g/GJ, is proved to be a good tool for predicting the fouling propensity of coals. There is also a relationship between the FGET and the growth rate.

基于二阶段算法的HJ-CCD数据过火区制图

利用环境减灾小卫星多光谱数据研究过火区的制图方法,并分析对比了4种植被指数对于过火区的分离性。结果表明:基于可见光和近红外的BAI(Burned Area Index)与GEMI(Global Environment Monitoring Index)指数对于过火区的分离能力较好。在此基础上,采用二阶段识别算法对实验区的过火区进行提取。首先采用严格的阈值提取燃烧较为严重的过火像元,并以此作为第二阶段过火区识别的“种子”点,该阶段以减少误判为目的;第二阶段采用区域生长提取其他过火区域,同时采取较为宽松的阈值作为生长准则,以减少漏判,最后得出过火区边界。精度验证结果表明:该方法提取的过火区误判率为5.5%,漏判率为12.7%。     

沈阳城市绿化植物综合评价分级选择

城市绿地系统是城市生态环境建设的核心内容。园林植物种类选择与配置，决定城市绿地系统生态效益与综合功能能否充分、有效发挥。对城市植物生态适应性及生态功能性相结合的综合评价，是合理应用选择城市园林植物的科学依据。通过专家咨询评价的方法，从生态适应能力、绿化生态效益、美化效果、抗病虫害性、抗污染性、经济效益等方面，全面系统地建立了沈阳市绿化树种生态功能与生态适应性评价应用的综合指标体系，对沈阳常见的230种绿化树种进行了评判与分级。评价结果表明：综合效能为一级植物有60种；二级植物为104种：三级植物50种：四级植物16种。     

Towards a System of Local House Price Indices

This paper argues that understanding of the performance and price structure of urban housing markets in the UK would be enhanced by limited investment in comprehensive systems for collecting data on housing transactions. These data would allow the construction of reliable and accurate indices at different levels of spatial aggregation. The empirical part of the paper uses data from the Western Australian Valuer General's Office to illustrate the data requirements and practical considerations in the construction of indices. The dataset provides comprehensive information on property attributes and the sales history of individual transactions and allows a comparison of the accuracy of a number of variants on the hedonic and repeat-sales index methods. The evidence suggests repeat-sales indices can be constructed on less detailed data with little loss of accuracy. The paper concludes by suggesting that repeat-sales methods, although largely ignored in the UK to date, lend themselves well to the development of a system of local price indices using the information recorded by the Land Registry.     

A comparative study of voltage stability indices in a power system

The paper compares the effectiveness of voltage stability indices in providing information about the proximity of voltage instability of a power system. Three simple voltage stability indices are proposed and their effectiveness is compared with some of the recently proposed indices. The comparison is carried out over a wide range of system operating conditions by changing the load power factor and feeder X/R ratios. Test results for the IEEE 57 bus and IEEE 118 bus system are presented.     

Severity Indices of Personality Problems (SIPP–118) in adolescents: Reliability and validity.

The Severity Indices of Personality Problems (SIPP–118; Verheul et al., 2008) is a self-report questionnaire focusing on core components of (mal)adaptive personality functioning. The SIPP–118 was developed and validated in an adult population. In adult populations, the 16 facets of the SIPP–118 fit into 5 higher order domains: self-control, identity integration, relational capacities, social concordance, and responsibility. In this study we present the 1st psychometric properties of the SIPP–118 in adolescents. We compared the SIPP–118 scores of a patient and a nonpatient sample of adolescents, and compared personality disordered and non-personality disordered adolescents. In addition, the relationship between scores on the SIPP–118 and other clinical instruments (Symptom Checklist—90–Revised; SCL–90–R; Derogatis, 1975; Dimensional Assessment of Personality Pathology—Basic Personality; DAPP–BQ; Livesley & Jackson, 2002) was investigated. The questionnaires were completed by 378 adolescent patients and 389 adolescents in the community. Facets appeared to be homogeneous, as alpha coefficients ranged from .62 to .89, indicating moderate to acceptable reliability. Also, more pathological SIPP–118 scores were found in the patient sample, and more specifically in the personality disordered sample, suggesting that the facet scores of the SIPP–118 can discriminate between various populations (divergent validity). Correlation with other clinical instruments was moderate to high (–.82 to .10). Taken together, the SIPP–118 seems to be a promising instrument measuring personality pathology in adolescents.
