In the 21st, intangible resources such as knowledge and information have become important asset in an organization and consequently knowledge creation has emerged as an assure managers have to deal with. The creation and management of knowledge has become a central concern to business and management, both as a source of value and as an opportunity to achieve and sustain competitive advantage. This...
Pilot-scale experiment was conducted on composting of sewage sludge from urban wastewater by recycling matured compost as a bulking agent. At the given ratio of sludge to matured compost = 1∶2(v/v), and aeration rate 0.05m3/(m3·min), final product was gained and analyzed by measurement of nutrient (nitrogen, phosphorus, and Potassium), heavy metals, and polyacrylamide (PAM). As the experiment shown,...
Microwave backscattering from two-dimensional wind-driven sea is investigated by using a refined composite surface model. In this composite model, a new choice of the cutoff wave number with wind-speed dependence and incident-frequency dependence is applied to separate the sea spectrum into large and small components in different sea states with increased accuracy. Meanwhile, a newly modified probability...
Target detecting and tracking based on video is one of the significant research field of computer vision, in this paper some research has been done on the small moving target under the background of sea level. In the process of target detecting, the moving targets detecting algorithm combining the method of background subtraction with the method of symmetrical difference is proposed in this paper...
