Business Intelligence is a concept of using information technology as a tool for achieving the competitiveness of businesses, the perception of risk that occurs in the environment within the firm, and the possibility of action. Complementary use of CRM systems and Business Intelligence, provides a holistic approach to customers which includes improvements in customer profiling, simpler detection value...
There are multiple interfaces viewed from the perspective of the interaction between brand and stakeholders and each interface has conflicts and other problems which affect the brand relationships. In this paper, the importance of stakeholders in the brand relationships is analyzed and the interfaces between major stakeholders are regarded as the most influential to the brand. The reasons for the...
This paper deals with a practical approach for planning WLAN hotspots to be underlaid within an existing 3G network. Given the number of access points (APs) and access routers (ARs), their locations, call handling capacities of ARs as well as serving GPRS Support Nodes (SGSNs), intra-WLAN handoff costs, and 3G/WLAN inter-system handoff costs, an important consideration for a mobile telecom service...
In virtue of its widespread application scenarios, especially in battlefield communication, disaster rescue, satellite and deep-space transmission, Delay-disruption Tolerant Network (hereinafter referred to as DTN) has become one of the most attractive focuses in research for future Internet. Due to the intermittent connectivity, mobility of nodes, signal interference, jamming in DTN, there exist...
For a right-invariant and controllable driftless system on SU(n), we consider a time-periodic reference trajectory along which the linearized control system generates su(n): such trajectories always exist and constitute the basic ingredient of Coron's return method. The open-loop controls that we propose, which rely on a left-invariant tracking error dynamics and on a fidelity-like Lyapunov function,...
This paper presents a formulation for fractional time-optimal control problems in terms of Riemann-Liouville fractional derivatives. For solution seeking purpose, the fractional operator is approximated using a rational approximation of the Hankel data matrix of the impulse response and the problem is reformulated. The problem is thoroughly studied for a fractional double integrator, and the solution...
Traditionally, reverse logistics has been viewed as unavoidable cost of doing business, forfeiting any chance of cost savings. In the recent past years, possible cost reductions, more rigid environmental legislations and increasing environmental concerns of consumers have led to more attention to reverse logistics. As cost pressures continue to mount in the competitive logistics industry, a growing...
For a successful real-time vision-based HCI system, inference from natural visual method is crucial. In this paper, we have aimed to provide interaction through gesture and posture recognition for alphabets and numbers. In addition, data fusion is carried out which integrates these systems to extract multiple meanings at the same time. 3D information is exploited for segmentation and detection of...
Except for daily functions, service Robot in family environment should have more intelligence, one of the most important abilities is to detect the unusual state of clients, and then be able to call for help timely. In order to achieve this, we propose an approach for the service robot to detect unusual state of the elder in a real-time way and construct a solution to the problem of the research model,...
Conceptual design is relative to customer requirements, ??taking customer demand as the direction?? has already become the dominant design concept. The framework and process model of integral conceptual design is provided, and a model of Requirement - Function - Principle - Structure is put forward. The mapping from requirement space to structure space is established by hierarchical automatic reasoning...
With the rapid development of science and technology, the integration of modern information technology and English curriculum in China universities has been an inevitable trend, which will have great effects and significance on the process of educational technology as well as foreign language teaching reform. This paper makes further exploration of main definitions, significance, characteristics as...
As the basic application of PKI (Public Key Infrastructure) theories and technologies, electronic authentication services (thereinafter referred to as EAS) is defined as to provide authentic identities and identity verification services for participants involved in network-based activities. Due to its complexity of constructing PKI, most application systems including e-business platforms need to integrate...
DFES (DFES, Design for Energy Saving) which incorporates energy-saving into the process of products design is an important part of Green Design. Aimed at the characteristics of possessing complementary advantages amongst AD (AD, Axiomatic Design), QFD (QFD, Quality Function Deployment) and TRIZ, an integration model of AD, QFD and TRIZ is set up. And this paper gives a detailed study on the structure...
In this paper, we propose an efficient method to estimate the radar cross section (RCS) mean and variance of a 2-D cylinder with random holes. This model has been applied extensively in microwave engineering, e.g., frequency selective surface (FSS). Firstly, we develop a deterministic RCS solver based on nodal Discontinuous Galerkin Finite Element Method (DG-FEM). Then, we quantify the RCS mean and...
Formulas for extremely low frequency (ELF) electromagnetic fields generated in a sea of finite depth by a submerged horizontal electric dipole (HED) are derived based on an air-water-seafloor three-layer model. Field components in seawater are computed using numerical integration technique and Euler's transform. The effects of frequency, sea depth, seabed conductivity and depth of submerged transmitting...
An accurate and efficient method to predict the shielding effectiveness (SE) of a rectangular enclosure with rectangular apertures is presented. A more accurate mathematical disposal is suggested for the calculation of slot impedance. And the point is to replace the former approximate expression by rigorous elliptical integration. Finally, the predicted results of the new method are compared with...
The RIA application of Internet constructed by integrating Hibernate, Spring, Struts and OpenLazlo to make the construction of Management Information System (MIS) faster and more effective. It is an optimal practice of constructing application of rich client based on Browser at present technique conditions.
Collaborative relationship in industrial clusters is taken as the basic unit of analysis. Relationship integration is defined as the function of transaction frequency and asset specificity. Process integration is defined as the function of process coordination, flexibility and reconfigurability. The relation of relationship integration and process integration is investigated. It is revealed that appropriate...
The scattering problem of acoustic wave by pre-fractal curvilinear rings system is considered. Making use of the integral equation technique, three dimensional mathematical model is reduce to two dimensional one. Application of the mechanical cubature method to the case of the parabolic ring is analyzed.
This paper presents a frequency domain based methodology using Walsh series, the method can be used to make a parameter identification of time-varying linear systems and time invariant linear systems. The methodology takes advantages of the operational properties available to most orthogonal series expression, i.e. integration, differentiation, product and coefficient matrices. Properties of Walsh...
