Much waste wood causing pollution and energy waste was produced in the processing of Pinus massoniana wood. However, hemicellulose extracted from Pinus massoniana waste can be transformed into bioenergy by means of pyrolysis, gasification, liquefaction, etc. Therefore, effects of deresination technology on extracting hemicellulose from Pinus massioniana were investigated by orthogonal and the whole...
A number of protocols have been developed to mitigate the threat against wireless sensor networks of an attacker finding nodes, compromising them, and using these nodes to eavesdrop or undermine the operation of the network. A more dangerous threat that has received less attention, however, is that of replica nodes, in which the attacker compromises a node, extracts its keying materials, and produces...
Information and Communications Technology(ICT) has been widely adopted by higher education institutions (HEIs) in the UK to for example provide greater access for different target learners and become vehicles for enriched pedagogical experiences. Many studies have discussed the great impact of ICT on teaching and learning and the changes it can bring. However, as revealed in literature as well as...
As a ideal raw material in bioenergy, extractives of Cunninghamia lanceolata wood are severely wasted. Therefore, the chemical components from Cunninghamia lanceolata wood were extracted with benzene /ethanol and identified by Py- GC/MS after concentration. Relative content of each component was determined by area normalization. 83 compounds of the extractives were identified. The main constituents...
Wood extractives for bioenergy with high additional value is looked upon as a strategy task. In this paper, the chemical components in the benzene/ethanol extractives of Eucalyptus urophylla wood were isolated and identified by Py-GC/MS so as to increase economic benefits. In this paper, the chemical components in the acetic ether extractives of Eucalyptus urophylla wood were isolated and identified...
As a waste in pulp, the acetone extractives of Eucalyptus urograndis wood severely polluted the water and wasted a lot of bleaching agents. Therefore, Py-GC/MS was used to analyze high-grade bioenergy utilization of acetone extractives of Eucalyptus urograndis wood. The relative content of each component was determined by peak area normalization. 33 compounds in the extractives were identified. The...
The Web-based lecture-scene playback system using the digital picture-card show has been studied to improve the educational quality of lectures with computer-aided slide presentations in universities. In this system, fine still images of lecture scenes, containing the lecturer, the blackboard, and the presentation screen, are periodically taken by a commercial digital photo camera, and the lecturer...
Guided by the theory of activity instruction and based on the instruction platform of LAMS, this paper studies the application of the theory of activity the learning in teaching practice and puts it into practice. Firstly, there is a brief introduction of LAMS and its characteristics and correlative applications, bringing up the principles of activity instruction and its correlative teaching strategy...
This paper tries to probe the influence of the organizational culture on language classroom at a newly-established local college. It firstly reviews the knowledge of the organizational culture and finds out its features, and then discusses how the organizational culture was greatly influenced by the host educational environment. On the basis of this, the paper interprets how organizational culture...
Wood extractives for bioenergy with high additional value is looked upon as a strategy task. In this paper, the chemical components in the benzene/ethanol extractives of Eucalyptus urophylla wood were isolated and identified by Py- GC/MS so as to increase economic benefits. The relative content of each component was determined by peak area normalization. 73 compounds in the extractives were identified...
This paper provides a reflection on the potential contribution of scientific computing with a view to improving energy system efficiency. First, we will consider energy efficiency globally in order to evaluate its potential. We will then focus on electricity, since electrical energy is interpreted as the universal vector of work. This will give us the understanding we need for envisaging a more efficient...
We utilize fatigue-crack-growth and load-spectra data published in the open literature to estimate aircraft probability of failure (PoF). We show that because single flight PoF values should not exceed 10-7, the behavior of the tail of the initial defect distribution significantly affects the predicted safe life. We demonstrate that even a slight variation of initial defect distribution parameters...
This paper presents a new game community support system and shows an experimental prototype system, based on an Internet social network system. The experimental results show the validity of this system and confirm the support function. Although competition among game creators or candidates is usually severe, they can communicate comfortably and collaborate with each other, using this system. As the...
This paper presents an "ontology-based" model for the production of Learning Designs in the field of Education for sustainable energy development. An ontology of the sustainable energy development domain and an educational model, designed incompliance with IEEE LOM standard and IMS LDspecification, constitute this model, in order to disprove the vagueness of "sustainable development",and...
This paper introduced the Sakai e-learning platform and blended learning, discussed the design of blended learning based on Sakai according to writerpsilas teaching experiences, including the design of learning resources, the design of learning activities and the design of learning evaluation. We found that Sakai platform can effectively implement the blended learning and greatly improve teaching...
In this paper, the author demonstrates the significance of cultivating studentpsilas memory firstly; and then put forward memory methods, including the method of reciting, the teaching method of understanding, the method of repeating, the method of associating, the method of amusing; the method of applying.
Information on the particle size distribution (PSD) of a particulate system is contained in the turbidity measurements. To obtain the PSD from such measurements, the inversion of a Fredholm integral of the first kind is required. To solve this ill-posed problem Tikhonov regularization technique can be used. The central issue in every regularization problem is the choice of an effective regularization...
In response to the demand for educational reform, this paper aims at cultivating college studentspsila intercultural communication competence on the basis of intercultural communication theory and empirical research method. Scenario training method, assisted with specific cases, was constructed, and hypothesis test tool was applied to analyzing its effect as well. The conclusion shows that this scenario...
All kinds of studies over the network, from a rather macroscopic perspective, are considered network study. It means, in other words, that learners achieve the goals of learning activities through the medium of network. But the problem is that learners may do this intentionally or unintentionally. This kind of general concept of learning exists not only in the network era but also in any past times...
