RFID complex event processing technology is the key point of RFID researching in these years. For the trend of great network application of RFID, this paper presents an RFID complex event processing model according to the features of RFID data and the disadvantage of the current models. Besides, the application in real scenario is also discussed.
News that RC frame-shear wall structure with specially shaped columns in service were severely torsional deformed and even collapsed are always reported, which is largely caused by the disadvantage layout of shear-walls. The layout of shear-walls of an actual structure of this type had been adjusted, and then methods of modal analysis and time-history analysis were used to study the seismic responses...

Asphalt concrete is a widely used paving material. Asphalt is employed as binders in the concrete while aggregate is employed as skeleton. Aggregates which can be divided into fine ones and course ones contribute the main strength of asphalt concrete. In order to ensure the strength of asphalt concrete, aggregates should be well dispersed in asphalt concrete. Therefore, evaluation of dispersion of...
Industrial symbiosis (IS) involves the inter-company exchanges of by-products, water and energy. The development of IS networks offers a potential regional platform to contribute to ensuring efficient utilization resources while minimizing the negative impacts on the environment. To illustrate the concept and potential application of IS, this paper focuses on the introduction of sulfur oriented IS...
In this paper, a novel miniaturized dual-mode ring bandpass filter is realized and studied. By using only one resonant-type left-handed unit with complementary split ring resonator to combine with a microstrip line, the ring configuration can provide two orthogonal zeroth-order resonance modes, and its occupied area can be reduced by about 82% compared with the conventional one. The filter has the...
On the basis of the field investigation of oil contamination in the Tianjin tidal flat of Bohai Sea, three representative sediments are sampled in the vertical direction of the shoreline, and their major physico-chemical properties are analyzed. In addition, dynamic curves and isotherms of aqueous oil adsorption on sediments have been measured. At last, retard coefficients (R) of aqueous oil are calculated...
Seawater pollution monitoring was conducted in a cage fish farm area and its vicinity (as control area) in Daya Bay, South China from 2001 to 2002 on a seasonal basis. The results showed that water environment factors of dissolved oxygen (DO) in summer and acid volatile sulfide(AVS) in spring both exceeded the criteria of the second class of sea water quality standards for fisheries in China with...
A high performance VLC decoder for DCT coefficients of MPEG-2 applications is proposed in this paper. Using parallel technique, a group-based approach is developed to decode a codeword within a single clock cycle. The codeword table is grouped according to the codeword prefix, so the current bitstream only needs to match with all the group prefixes instead of all possible codewords in the codeword...
In this paper, a two-dimensional statistical model for a single cathode spot of vacuum arc with copper cathode has been established to simulate its random walk and retrograde motion under external transverse magnetic field. In this preliminary work, a parameter, A, which was not yet related with the strength of applied transverse magnetic field in present work, was used to denote the different probabilities...
Predicting failures from software input is still a tough issue. Two models, namely the surface model and structure model, are presented in this paper to predict failure by applying the maximum entropy principle. The surface model forecasts a failure from the statistical co-occurrence between input and failure, while the structure model does from the statistical cause-effect between fault and failure...
