摘要：Imagination should always exist in any artistic creation, and the art can be more flawless. Similarly, vocal music teaching also needs imagination. The power of the sound production lies in breathing, and the singers can control excellent sound production only if longterm and large trainings are undergone. Imagination is one of the indispensable important means in vocal music teaching. Therefore, it should be reasonably used in the vocal music teaching. In this paper, imagination is first reviewed, and then the role and application of imagination in the vocal music teaching is analyzed and discussed, so that some references provided for the better application of imagination in the vocal music teaching.

摘要：Hemingway’s“Indian Camp”is a short story first published in 1924 in The Transatlantic Review,and then in his short story collection In Our Time in *** is considered to be one of Hemingway’s favorites and the best of the ***,it also sparked considerable controversy for the involvement of the seemingly superfluous character Uncle *** 1960s,Uncle George has always been considered to be the biological father of the newborn baby the Indian woman has delivered and has been claimed to be responsible for the suicide of the Indian husband,which has been falsified by the previous paper of the ***,it’s of great necessity to explore the role of Uncle George to manifest the significance of this *** close reading of the story,it can be found that Uncle George is a helpful assistant of Doctor Adams,a powerful foil of other protagonists and a useful supporter of the reliable narrator.

摘要：Coordination technology addresses the construction of open, flexible systems from active and independent software agents in concurrent and distributed systems. In most open distributed applications, multiple agents need interaction and communication to achieve their overall goal. Coordination technologies for the Internet typically are concerned with enabling interaction among agents and helping them cooperate with each other. At the same time, access control should also be considered to constrain interaction to make it harmless. Access control should be regarded as the security counterpart of coordination. At present, the combination of coordination and access control remains an open problem. Thus, we propose a role Dased coordination model with policy enforcement in agent application systems. In this model, coordination is combined with access control so as to fully characterize the interactions in agent systems. A set of agents interacting with each other for a common global system task constitutes a coordination group. role based access control is applied in this model to prevent unauthorized accesses. Coordination policy is enforced in a distributed manner so that the model can be applied to the open distributed systems such as Internet. An Internet online auction system is presented as a case study to illustrate the proposed coordination model and finally the performance analysis of the model is introduced.

摘要：By defining the concept of vernacular cultures,3 basic elements of vernacular cultures were refined according to different demonstration forms,specifically,vernacular materials and things,vernacular cultural context and vernacular *** Normal University,Wuhan University and Sichuan Institute of Fine Arts were taken respectively as landscape design representatives of campus in east,central and west China to elaborate application of vernacular cultures in campus landscape ***,development trend of education role of campus landscapes was discussed from the perspectives of"modeling after the nature,building according to users'needs","seeking differences on the basis of maintaining similarities,recording the history and prospecting the future","green and low-carbon,dynamic and sustainable",so as to ensure campus landscapes to develop their educational effects subtly.

摘要：Water and sediment in four-inlet river system and the water level at Chenglingji reflect the current relationship between Yangtze River and Dongting Lake. Since the flow in four-inlet river system is reduced gradually, the lake water level is also reduced, resulting in shrunk lake area, channelized lake, narrowed channel and reduced rfve beach. Facing the changed relationship the River and the Lake after the utilization of Three Gorges Project, the Chenglingji control engineering at the outlet of Dongting Lake and the dredging of four-inlet river system are car- ried out. Thus the roles of flood control （1.67x101~ m3） and water amount regulation （2.3~101~ m3） of Dongting Lake are fully played. The Dongting Lake plays compen- sating and scheduling roles in the flood control and water storage of the Three Gorges Reservoir. It can reduce a volume of 4.0x109 m3 of excess flood around Chenglingji. In addition, it can also provide a water supply of 5 000 m3/s to the lower reaches of Yangtze River during the dry season for about 30 d. The Dongt- ing Lake plays an important role in the stabilization of ecological environment in the watershed, the regional water resources security and the protection of Dongting Lake and Yangtze River.

摘要：The present study will focus on teacher's roles, while providing a description of the current "state of the art," as regards the difficulties and problems encountered. In other words, an attempt will be made to trace some of the intrinsic factors that, either positively or negatively, affect teaching and learning habits, with a view to fostering a holistic approach to education and forging constructive, interpersonal relationships in the classroom which can facilitate the educational process.

摘要：This research was performed within a software engineering workshop for Computer Science students. For addressing the soft skills issues required by the industry, the course was delivered as a workshop with various (inter and intra) team based activities. An additional objective of outlining the importance of software maintainability issues was achieved through team-based role play. There were three assignments in which each team had to continue the work performed by another team, thus creating a dependency between the teams as might happen during maintenance. The main research study objective was to examine the effect of employing this kind of a team-based role-play peer-review on the students’ learning process regarding maintainability. Data referring to the students’ perceptions is presented and analyzed in addition to student reflections on the workshop which demonstrate their expanded understanding of the design and application process.

摘要：Compared with the flat architecture in the design of sensor networks, the hierarchical architecture gains much attractive for the reason of scalability, management and energy efficiency. In order to distribute the energy evenly, nodes act the cluster head in some orders. The existing approaches don’t pay a critical attention to the overhead during the role rotations. And the duration of a round is a priori, which is very application-specific. An energy-aware hierarchical architecture design scheme is put forward in this paper, namely, Adaptive Minimum Rotational Cost (AMRC) cluster formation scheme. The decision of beginning a new round is made adaptively by the cluster head itself. It combines the dynamic and static advantages in the clustering architecture. The simulation results demonstrate AMRC outperforms some other clustering protocols in many aspects.

摘要：Given a set of requirements structured as design problems, we can apply design patterns to solve each problem individually. Much of the published literature on design patterns addresses this problem—pattern association;however, there is no systematic and practical way that shows how to integrate those individual solutions together. We propose a compositional model based on design patterns by abstracting their behavioral model using role modeling constructs. This approach describes how to transform a design pattern into a role model that can be used to assemble a software application. The role model captures the behavioral relationship between participant components in the design pattern. Our approach offers a complete practical design and implementation strategies, adapted from DCI (Data, Context, and Interaction) architecture. We demonstrate our technique by presenting a simple case study complete with design and implementation code. We also present a simple to follow process that provides guidelines of what to do and how to do it.
