Robotisation of forestry harvesting in New Zealand has the potential to achieve great productivity benefits and support the timber industry in the face of global market competition. Recognition and localization of tree trunks is the first critical operation for an autonomous forestry harvesting robot and is a challenging task due to variations of illumination under normal forestry harvesting conditions...
Computational sprinting has been proposed to improve responsiveness for the intermittent computational demands of many current and emerging mobile applications by briefly activating reserve cores and/or boosting frequency and voltage to power levels that far exceed the system's sustained cooling capability. In this work, we focus on the thermal consequences of computational sprinting, studying the...
With the rapid development of mobile App advertising, how to allocate App advertising more reasonable is now need to be studied. This paper proposes an App advertising auction mechanism based on optimal keyword auctions. First, we analyze the development trend of the App advertising and obtain the result that the core competitiveness of mobile advertising lies in the precise. Next, we describe the...
How to promote the use of new information technology (IT) among employees has become a major challenge for enterprises' informatization construction. Most of the extant studies on the adoption of IT are based on the cognitive theory. By contrast, little research has been engaged in exploring the effect of emotions on the IT use. The aim of this study is to explore the relationship between emotions...
A low noise interface application-specific integrated circuit (ASIC) for capacitive accelerometer is presented in this paper. A low-noise low-offset charge integrator is proposed to improve performance of the system. Correlated double sampling, closed-loop operational mode and PID controller are employed in this circuit to minimize the noise, offset and improve stability of the system. Meanwhile,...
It's a international trend for medicine sectors to adoption e-commerce. However, majority Chinese medicine companies are still on hesitant and indecisive manner. Based on the extant researches, this paper develops a multi-dimensional model about factors influencing the adoption of e-commerce in medicine companies and presents a set of testable hypotheses. Then using data from a survey of medicine...
With computer and network technology developing, the educational resources on the Internet are also growing exponentially. To locate useful resources from the mass and diverse information is crucial. When using general search engine to search information in a specific field, the results usually cover all fields which can't provide accurate retrieval service for users. However, powerful vertical search...
Based on the theory of large scale system general optimization, a model for optimal deployment of regional water resources with multi-sources and multi-consumers was developed. A new nonlinear integrated objective function was introduced in the model, which synthetically takes economic benefit, expense of water usage and water resource's equilibrium distribution into account.With the restriction of...
Water environmental pollution is a widely attended important problem. With the development of economy and improvement of living standard, the discharge quantity of city sewage, power plant cooling water, etc. is increasing gradually. Because the discharge process is concerned with jet behavior, so it is significant to study on flow behavior near discharge outlet of sewage treated building in the theory...
Based on the input-output data , a multiple-model modeling method is suggested for the complex nonlinear system. Firstly, fuzzy partition is employed to on-line clustering for the input-output data; and then, the least-squares (LS) algorithm is employed to construct the local model for each clustering, and the parameter of each local model is updated by the new data. The proposed algorithm takes advantage...
Summary form only given. Many axisymmetric structures in engineering subjected to non-axisymmetric loads cannot be treated as an axisymmetric problem. However, they can be solved through a series of two-dimensional problem by expanding the load in terms of Fourier series in the circumferential direction based on the geometric symmetric of the structures. This work presents a harmonic element for transversely...
A novel wireless transmission method was proposed in this paper. The new method combined non-orthogonal perfect space-time block codes (NPSTBC) and orthogonal frequency division multiplexing (OFDM) together. Compared with orthogonal space-time block codes, the NPSTBC based cyclic division algebras can achieve full-diversity transmission. The low-complexity sphere decoder is used to realize the decoding...
This study focuses on the effects of pollution incidents on sensitive receptors. A classification index system for cross-border emergent atmospheric environmental risk sources has been developed which considers the environmental factors near the risk source and the potential for cross-border pollution that influence the extent of possible harm from a risk source, and evaluating criteria for indexes...
The novel and revolutionary concept of real Vacuum Laser Acceleration proof of principle is described in this paper. The simulation with the current BNL-ATF parameter shows that electron beam can get net energy from intense laser beam. The initial 20MeV electron beam with energy spread of 10-3 can get hundreds of KeV energy gain with energy spread of 10-2 by interacting with a laser a0=1. The proposal...
Pulse signal checking is one of the four Chinese traditional medical diagnosis methods. But few of doctors can use these techniques now in practical diagnosis because of difficulty of understanding. In this paper, a modern pulse signal processing system based on TMS320C6713 DSP for tumor sickness diagnosis and syndromes analysis is described. Pulse signal is sampled with 300 Hz frequency and 8 bits...
In this paper, an e-learning system model which supported the four-tier system architecture and agent technology are introduced into network education, and the construction of high-efficiency, high-performance e-learning platform is useful attempted. In addition, a remote distance learning system based on agent is constructed and at present the system has already improved the system load capacity,...
A moving-bank based intelligent control method was introduced to deal with the complex nonlinear system. Firstly, the predictive model of the nonlinear system was modeled online based on the least squares support vector machine (LS-SVM), and the linearized predictive model was acquired. Secondly, the multiple fixed model bank was dynamically updated based on the linearized predictive model. Finally,...
According to the idea of phase space reconstruction of scalar time series, phase space reconstruction of multivariate time series based on the short-term electric load is presented. The good time delay is chosen for each scalar time series by mutual information. The method to get the minimum embedding dimension is based on minimum forecasting errors. The choice of optimal neighbor points is presented...
