Taking the city of Qitaihe is as an example in order to provide practical methods for the selection of leading industries for coal resource cities, this paper establishes the specific operation scheme for selection of leading industries according to the actual situation of coal resource cities based on the theory of coupling coordination together with the coupling coordination for technological innovation. The results show that the degree for coupling coordination of the technological innovation for each alternative industry differentiates with the development of coal resource cities. For example, the average degree of food processing industry from agricultural produce is 0.9. Therefore, coal resource cities should develop some industries related to coal industry, such as coking industry, some chemical and medicines industry and non-metallic mineral products manufacturing, in the near future, however, some industries with greater market and influence potentials and low carbon emissions should be attached much importance to in the future. 展开更多

In industrial processes,there exist faults that have complex effect on process variables.Complex and simple faults are defined according to their effect dimensions.The conventional approaches based on structured residuals cannot isolate complex faults.This paper presents a multi-level strategy for complex fault isolation.An extraction procedure is employed to reduce the complex faults to simple ones and assign them to several levels.On each level,faults are isolated by their different responses in the structured residuals.Each residual is obtained insensitive to one fault but more sensitive to others.The faults on different levels are verified to have different residual responses and will not be confused.An entire incidence matrix containing residual response characteristics of all faults is obtained,based on which faults can be isolated.The proposed method is applied in the Tennessee Eastman process example,and the effectiveness and advantage are demonstrated. 展开更多

The concept of research-based social work is introduced and discussed from the point of view of preconditions for its realization. Attention is paid both to the academic research of social work and to opportunities for developing a knowledge-producing social work practice. Both of these are seen as essential elements of a research-based profession. On the one hand, the academic research is necessary for development of social work as a research-based professional system, and on the other hand, a knowledge-producing practice, conducted by research-oriented practitioners, can only be realized within such a system. Historically, social work has been partly developed as a knowledge-applying instead of a knowledge-producing profession, although the central founding pioneers emphasized the importance of an own-knowledge basis and theory formation, as well as the idea of knowledge-producing practice based on a corresponding professional identity. The future of social work as a professional system in modern society may depend decisively on how it develops a research-based professional identity, not only in the sense of academic research but also through practitioners with research orientation. These are practitioners who would be capable of research-based working in terms of creative knowledge production, thus of developing social work as a credible research-based profession. This can be created only through education in which the development of necessary professional skills is linked to advanced academic meta-skills. There are good reasons to suspect that a three-year education is too short for this. 展开更多

In order to upgrade the conventional wood pellet, Japanese softwood and hardwood chips were torrefied at around 200-350℃, and pelletized. The characteristics of the torrefied material/pellets such as their calorific value, grinding energy, pelletizing energy and elemental composition, were also evaluated in this study. The calorific value rose with increasing torrefaction temperature and exceeded 25 MJ/kg (an increase of nearly 40% compared to the untreated state) for torrefaction at around 350℃. The grinding energy greatly decreased with increasing torrefaction temperature, and the reduction was larger for Japanese oak hardwood chips. The pelletization energy for the torrefied material tended to be slightly smaller than in the untreated case. People named such torrefied pellet as "hyper wood pellet". 展开更多

The field experiment was conducted at Pulses Research Centre of Bangladesh Agricultural Institute (BARI), Ishurdi, Pabna, Bangladesh during rabi season of 2009 to find out the suitable management package for better plant establishment and higher yield of lentil under relay cropping. The experiment was based on three genotypes--Rajbari local, X95S-167(4) and X95S-136; two types of rice straw height--I 0 cm and 30 cm, three seed rates (kg/ha)--e.g., 30, 50 and 60, and three levels of fertilizer--control, 30-60-20 kg/ha of N-P2Os-K20 and 30-60-30 kg/ha of N-P2Os-KzO. The experiment was laid out in a split-split-split-plot design with three replications. Genotype was placed in the main-plot, rice straw height was in the sub-plot, seed rate was in the sub-sub-plot and fertilizer level was in the sub-sub-sub-plot. From this study, it was observed that lentil genotype X95S-136X planted with a rice straw height under 30 cm, at a seed rate of 50 kg/ha, and with a fertilizer level at 30-60-30 kg/ha of N-P2Os-K20 produced the highest lentil seed yield of 2,070 kg/ha and the lowest seed yield (550 kg/ha ) was obtained from genotype Rajbari local, planted with a rice straw height under 10 cm, at a seed rate of 30 kg/ha and no fertilizer. Similar result regarding seed and straw yield was also found in the farmer's field. The accession X95S-136 along with improved production technologies produced the highest grain and straw yield, and net return but the lowest grain and straw yield as well as net return were obtained by Rajbari local in the demonstration field. It was also identified that, by the inclusion of lentil in the transplanted monsoon rice field, lands could be brought under lentil cultivation to enhance lentil production, provide human nutrition and also to ensure soil health improvement for sustainable production system. 展开更多

The network services today require extremely agile and mobile, however, the traditional IP infrastructures are so rigid that cannot fit services well. A way should be put forward to automate the network to improve responsiveness to change. SDN and network virtualization(NV) are two hottest approaches to make networking more automated and scalable to support virtualized and cloud environments. Network virtualization combines hardware and software network resources and network functionality into a single virtual network. SDN is created to simplify traffic management and achieve operational efficiencies by establish and exercising central control over packet forwarding. In this paper, we focus on the situation where SDN controller needs to connect two virtual networks temporarily. We put forward three algorithms to try to make this connection more effective and evaluate these three algorithms. 展开更多

Earthquake induced landslides are one of the most severe geo-environmental hazards that cause enormous damage to infrastructure, property, and loss of life in Nuweiba area. This study developed a model for mapping the earthquake-induced landslide susceptibility in Nuweiba area in Egypt with considerations of geological, geomorphological, topographical, and seismological factors. An integrated approach of remote sensing and GIS technologies were applied for that target. Several data sources including Terra SAR-X and SPOT 5 satellite imagery, topographic maps, field data, and other geospatial resources were used to model landslide susceptibility. These data were used specifically to produce important thematic layers contributing to landslide occurrences in the region. A rating scheme was developed to assign ranks for the thematic layers and weights for their classes based on their contribution in landslide susceptibility. The ranks and weights were defined based on the knowledge from field survey and authors experiences related to the study area. The landslide susceptibility map delineates the hazard zones to three relative classes of susceptibility: high, moderate, and low. Therefore, the current approach provides a way to assess landslide hazards and serves for geo-hazard planning and prediction in Nuweiba area. 展开更多

The writings of Soren Kierkegaard provide a theological and philosophical foundation as experienced in the life of a tragic hero and a knight of faith. It will be shown that the ethical dimensions as experienced by Abraham in "Fear and Trembling" provide a core ontology in the lives of Jan Patocka and Viktor Frankl. Jan Parocka developed a phenomenological, Kierkegaardian, existential approach in his writings and lectures that enabled him to undergo his interrogations by the Czech communist secret police. The World War II concentration camp experiences of Viktor Frankl led him to develop a Kierkegaardian, existential, noetic approach to discover meaning under inhuman living conditions. We, as humans, are searching for a spiritual core to transcendence, as seen in the writings of Kierkeggard to reach beyond ourselves in the fully human dimension of the good, the true, and the beautiful in faith and in love. Special attention will be given to the lives of Patocka, Frankl, and how Kierkegaard's theology and philosophy contribute a transhistorical, phenomenological, existential, meaning-centered approach to understanding trauma, especially in the lives of returning veterans and their families. 展开更多
