Abstract: This paper introduces the weakness of small and medium-sized material enterprises first, and then analyzes the primary component of search engine marketing according to the experience of the authors and other scholars. Combined with the practical situation of small and medium-sized material enterprises, this paper proposes to do search engine marketing from the angle of search engine optimization, paid listing, search engine blog marketing and search engine community marketing. Among them, search engine optimization as the major part of search engine marketing is introduced in detail and applied with specific instructions.

Abstract: characteristics of current MIS System are massive data、diverse data and complex functions. This kind of System requires higher requirement to Storage and Computing. This paper proposes a way to resolve it by build cloud computing platform by making full use of large number of idle computers.

Abstract: The folksonomy compared with the traditional classification and thematic approach, is a completely spontaneous by the user, which using natural language, uncontrolled information organization, easier to be accepted by public users. But on the one hand, the folksonomy due to the elimination of the strict vocabulary control and hierarchical structure has too many faults, such as fuzzy semantic retrieval accuracy and low recall rate, as well as tag the abuse of information garbage. In this paper, the author uses the ontology to standardize the folksonomy, and try to improve the effect of folksonomy for information organization and retrieval.

Abstract: This paper is to explore how to apply the research achievement to the development of the real estate knowledge management system. It will give the design principle and the frame of the real estate knowledge management prototype system based on the knowledge acquisition methods based agent cooperation search model and genetic algorithm based knowledge discovery method, and the design plans of its major modules. The prototype system's objective is to verify the feasibility of the design plan of the real estate knowledge management system to develop in the future.

Abstract: QNew is different from the common Internet video, for it shares the readers with its curriculum self-timer videos. It has the spirit of the open textbook-assisted learning. It also focuses on the uploading, sharing, and expansion of the users’ information. Typically, 5 to 10 minutes is the limit, as long as the teachers and students have finished registering, they can upload their videos of teaching. Website platform is composed of the sub-platform of course classification and message board, which furnishes the teachers and students with the service of Internet Hit.. QNew is the website mentioned in this article, and after its full development, it will not only become one of the departmental remedial resources, but also as an interdisciplinary and inter-campus teaching platform.

Abstract: Since the railway bridge has many spans and long distance, it is complicated and time-consuming to model and analyze the random earthquake response of the structure with the finite element software. The dynamic frequency response equation of longitudinal vibration of simply supported girder bridge is established with the unit impulse as the input excitation, based on the motion equation of the MDF system and he transfer matrix principle. Finally, Taking seven cross-simply supported girder bridge as an example, the frequency response of the vertical displacement and axial force are computed with the Rayleigh damping. The result of the vertical displacement and axial force shows that: the mid-span displacement of spans in the middle of the bridge is slightly larger than that of the side spans while the difference between each value is small, but the mid-span axial force of spans in the ends of the bridge is significantly larger than that of the middle spans. And the corresponding Fourier amplitude spectrums under pulse loads are given. With this method, it is convenient to program and calculate the dynamic frequency response of the simply supported girder bridge by mathematical software, and it is available to provide a reference for the random seismic design of the structure.

Abstract: In the design of the rise of classical wind hot flashes, how to reference to traditional natural landscape gardening technologies, thinking method and landscape elements, symbol of the new constitutional relations, and into the modern landscape design, and create a new character space, make the classical elements, symbol and modern garden good fusion, create with regional and national characteristics of modern landscape design.

Abstract: Water conservancy project in the northern cold regions, most of the channel lining structure using polystyrene board plus the compound in the form of precast concrete panels, due to the lack of convenient and practical theoretical model for the guidance of the composite channel lining alone experience and experimental data the size of its structure, the actual cold water channels and the climate and environment in which concrete composite lining water channels necessary assumptions, the use of the theory of the mechanics of composite materials, concrete structures and other composite channel lining structure force analysis, the slope drainage board, backplane, thermal insulation board and other internal force calculation formula, combined with the relevant norms, established channels of composite lining structure failure criteria, and provides a theoretical basis for engineering design and construction of the composite lining channels.

Abstract: This paper shows the performance of multi-layer soil electric resistivity model comparing with two-layer characterizations in geotechnical investigations. In conventional model, there are inter-relationships between soil apparent electrical resistivity (ρ) and several soil physical or chemical properties. These empirical relationships show limitations to obtain specific soil characterizations of different layers with. Multi-layer true resistivity model is the improvement of conventional two-layer earth model including the criteria of four points probe method. Multi-layer soil resistivity profile shows more accuracy to obtain near surface soil characteristics including the types of soil and rocks, and to detect anomalous materials in soil profile. Alternatively, apparent resistivity in two-layer model can be used to obtain deeper profile of soil characteristics. In this multi-layer soil model, the soil resistivity and resistivity ratio corresponding to the depth in soil medium are considered for geotechnical investigations. Two-layer model includes soil apparent resistivity according to probe distances in depth corresponding resistivity profile. This paper is important for including criteria and performance of multi-layer soil resistivity model and conventional two-layer model for geotechnical characterizations.

Abstract: Suspender is an important component of through arch bridge which transfers loads from bridge deck to arch rib, and its mechanical property is closely related to the safety of whole bridge. When suspender is damaged, the change of its tension will lead to internal force redistributions of the arch bridge. In this thesis, taken Xinkai River Bridge of Harbin-Dalian high-speed railway as a case study, which is the first long-span steel-box stacked arch bridge for high-speed railway in China, a finite element model is established by using the MIDAS/Civil software. By analyzing the calculation results and comparing static performances under non-destructive conditions, the influence of damage of suspenders on steel-box stacked arch bridge is summarized, which can provide reference data for health evaluation of the bridge during service period.
