Edutainment 2006 is an international conference on research and development on e-learning and digital entertainment. The main purpose of the conference is the d- cussion, information and opinions exchange on the development and use of such s- tems. It provides a very interesting opportunity for researchers who want to attend or present communications at these events. The conference includes plenary...
This book covers various technological aspects of sustainable energy ecosystems and processes that improve energy efficiency, and reduce and sequestrate carbon dioxide (CO2) and other greenhouse emissions. Papers emphasize the need for sustainable technologies in extractive metallurgy, materials processing and manufacturing industries with reduced energy consumption and CO2 emission. Industrial energy...
The time series model is decomposed into the trend items, cycle items and random items, respectively extracted by the establishment of the various forecasting model, the model is applied to the Chahayang farm in 1956 to 2008 on-year growth period crops fitting rainfall forecast, the results show that the model can reveal the crop growth period variation of monthly rainfall, for the rational development...
Bilinear time-frequency distribution can token overall mechanical failure signal characteristics, but it's found that strong cross-terms exist which results in frequency aliasing and information loss appear. In this paper, the time-frequency analyze is used to identificate the weak winking signal in complex background. Arithmetic based on ARMA model filter is bring forward to solve cross-terms problem...
In discrete manufacturing companies, the knowledge existing throughout the product lifecycle (PL) should be managed effectively. Much explicit and implicit knowledge is produced in the different stages of product lifecycle or different production departments. In order to make the knowledge shared and reused among the workers of the enterprise, this paper focuses on: introducing the ontology into the...
The purpose of this study was to identify switching costs and examine the moderating effect of switching costs on buyer loyalty model in the B2B e-marketplace. Then a questionnaire was constructed and data were collected from 649 buyers of a Chinese B2B e-marketplace in 114 countries all over the world. Multi-group analysis was applied to examine the moderating effect of switching costs. Finally,...
Based on management experimental method, the paper studies logistics customer complaint management. There are two purposes in our research. One is to analyze the factors influencing customer complaining behaviors and the factors influencing logistics service staffs how to deal with complaints. The other is how to choose suitable logistics service staffs. The study is helpful to improve the abilities...
With high compression ratio performance, fractal image compression technology becomes a hot topic of research of image compression techniques. However, the encoding time of traditional fractal compression technique is too long to achieve real-time image compression, so it cannot be widely used. Based on the theory of fractal image compression; this paper raised an improved algorithm form the aspect...
The Physical Downlink Control Channel (PDCCH) is used to signal dynamic resource assignment information in the Long Term Evolution (LTE) system. In the presence of numerous active users, the system performance is likely to be hindered by shortage of control channel resource. In this paper, several simple algorithms are brought forward for making efficient PDCCH resource allocation. We first propose...
We present a novel MEMS application aimed at laser based gas sensing. A low-cost MEMS based external intensity modulator for a laser diode source has been realised and applied to photoacoustic spectroscopy. By using a MEMS based modulator, pure intensity modulation of the laser emission is achieved without the accompanying wavelength modulation which occurs with diode current modulation. This reduces...
A hybrid two-axis MEMS scanning mirror has been fabricated incorporating two different actuation mechanisms for its orthogonal rotation axes. The 2 mm diameter mirror is rotated about one axis using an electrostatic comb-drive for fast resonance movement and about the other axis using two out-of-plane electrothermal actuators. This hybrid actuation arrangement enables fast sweeps (at the mechanical...
Controlled synthesis of ultra-long AlN nanowire arrays in different growth density has been successfully realized by direct nitridation of Al powders for the first time. These AlN nanowires have an average diameter of about 100 nm and their mean length is over 50 μm. All the synthesized ultra-long nanowires are pure single crystalline h-AlN structures with the growth orientation of [0001]. We propose...
Cosine transform seldom applies to pattern and object recognition due to its poor capabilities in describing image and calculating efficiency. In order to resolve these problems, a Bi-discrete radial cosine transform is proposed. The new cosine transform has two particular properties. First it takes Mukundan's square-to-circular transformation to project the square to the circle grids. Second different...
Tungsten oxide nanostructures have been paid much attention because of their particular physics and chemical properties. But until now, it is difficult to realize patterned growth of tungsten oxide nanowire arrays. In this paper, we demonstrate that tungsten oxide nanowire arrays can be controllably synthesized in patterned arrays at low temperature of 550°C by a simple ceramic template method. The...
In multi-cluster sensor network, the inter-cluster interference is a factor to bring packet loss and energy cost. In this paper, a slot pre-allocation algorism to deal with the inter-cluster interference in TDMA based sensor network is proposed. The algorism is totally based on TDMA MAC, without using frequency enlarged methods such as CDMA and FDMA, can be easily implemented and not demands additional...
To improve the automatic detection efficiency of photoelectric encoder, an auto-detection system of photoelectric encoder is designed using DSP (TMS320F2812) as the core device. A 21-bit high accuracy photoelectric encoder is used as the angle standard. It is connected to the detected photoelectric encoder coaxially. They will rotate synchronously under the driving of electric motor. Data acquisition...
Reputation of the entities is very important for other entities to evaluate the trustworthiness of them. This paper analyzes the efficiency of the query in different frameworks using differential methods. In centralized framework, there is a centre to store reputations and provide them to other entities, and the number of queries is only once for every query, so the efficiency is very high, but it...
Based on the China economy data 1996-2005, two issues are addressed in this paper. First, we examine the ability of the DSGE model to describe stylized facts about China economy. The model succeeds to replicate the variability observed in 1996-2005. Second, we compare two methods of motivating money in DSGE Model. Drawing on our econometric analysis, we argue that the cash-in-advance model, closed...
The modeling and simulation of container terminal logistics system is rapidly developed and widely applied. This paper describes three parts of the modeling and simulation of container terminal logistics system, which includes Logistics system modeling technology, Verification Validation and Accreditation and screening test, and then the research approach and target, the primary coverage and the key...
By using the quarterly data of 1996-2005 in China, this paper evaluates the usefulness of a monetary policy rule designed for developed economies. Drawing on our econometric analysis, we argue that the model comes closer to the data of China ,it is an ideal framework for chinese monetary policy analysis. The paper also suggests to make modifications of the typical policy rule to explain Chinese economy...
