Bioethanol will play a significant role in energy structure adjustment and greenhouse gas mitigation the future, especially transport sector. As bioethanol production with grain crops may become obsolete due to food security concerns, Chinese government has advocated development of non-grain bioethanol. According current actual situation China’s Liquid Biofuel Development Roadmap, we defined th...

The paper provides a logical characterisation of distributed processing of SPARQL queries. The principal notion analysed is that of a distribution scheme; a pair consisting of an evaluation rule and a distribution function. Different choices of evaluation rules and distribution functions give different federation schemes that are proved to be sound and complete wrt. different selections of RDF ...

The paper presents an investigation of agroecosystem dynamics with an application to yield data from England over the period 1885-2012. The analysis relies on a Threshold Quantile Autoregressive (TQAR) model. The model allows for lag effects to vary across quantiles of the distribution as well as with the values taken by the lagged variables. While it includes as special case the quantile autor...

Estimates of crop yield are desirable for managing agricultural lands. Remote sensing is the one technology that can give an unbiased view of large areas, with spatially explicit information distribution and time repetition, and has thus been widely used to estimate crop yield and offers great potential for monitoring production, yet the uncertainties associated with large-scale crop yield esti...

Increases in the severity and frequency of drought in a warming climate may negatively impact agricultural production and food security. Unlike previous studies that have estimated agricultural impacts of climate condition using single-crop yield distributions, we develop a multivariate probabilistic model that uses projected climatic conditions (e.g., precipitation amount or soil moisture) thr...

The dependence of the e€ective secondary electron yield on the potential distribution and the target materials was investigated by means of electron transport simulation in the sheath with the potential distribution calculated for the di€erent emission characteristics of Be (Zˆ 4), C (Zˆ 6), Mo (Zˆ 42) and W (Zˆ 74) as the target materials. For lower primary energy incidence the e€ective second...
