Soil contamination with polycyclic aromatic hydro-carbons (PAHs) is an increasing problem in China. An field survey was conducted in the industrial field and adjacent soils of Benxi Iron and Steel Group Corporation of Benxi, China to investigate the contents and distribution of the PAHs of soil, and a health risk assessment was carried out with total toxicity equivalence concentration (TTEC) of 15...
Current approaches for generating wrappers for web page extraction suffer from the requirement of huge amount of labeled training pages to obtain satisfying results. On the other hand, the quality of data extracted by fully automatic methods is not reliable. In this paper, we propose a novel method to facilitate wrapper generation by combining wrapper induction and page analysis approaches. In addition...
Most knowledge development efforts in intellectual capital and creative industries have focused on Western economies and companies. This study develops and tests empirically a theoretical model that focuses on how intellectual capital variables influence firm performance in developing countries under the conditions of knowledge economy. Based on the literature and in-depth interviews, the authors...
Many existing human detection systems are based on sub-window classification, namely detection is done by enumerating rectangular sub-images in the 2D image space. Detection rate of such approaches may be affected by perspective distortion and tilted orientation of the human in images. To overcome this problem without re-training the classifier, we develop a 3D search method. A search grid is defined...
Segmentation and tracking of multiple humans in crowded situations is made difficult by interobject occlusion. We propose a model-based approach to interpret the image observations by multiple partially occluded human hypotheses in a Bayesian framework. We define a joint image likelihood for multiple humans based on the appearance of the humans, the visibility of the body obtained by occlusion reasoning,...
