The authors' approach to intelligent marketing in smart cities uses large-scale crowdsourcing based on mobile user behavior for market planning. Unlike most work, which focuses on the client side, the proposed method is intended for market planning from a marketer perspective. The proposed system tracks and examines user trails via mobile devices. To support distributed analysis for big data, computer...
Understanding the dynamics of information spreading over social networks has been of great interest for a long time. It has been convincingly demonstrated that the topology of a network can significantly affect information spreading over it. Information spreading is often compared on small-world networks and random networks. In this paper, we find that the heterogeneity of spreading abilities of network...
Second level adaptation using multiple models for the adaptive control of linear systems with unknown parameters was introduced in [1], and its robustness properties were discussed in [2]. In both cases, the plant, the identification models, and the reference model were assumed to be described by state equations in companion form, with all state variables accessible.
RT-LAB simulation platform shows various abnormities in its application of complex electromechanical simulation system, which cause difficulty in operation. Aiming at these problems, this paper has described the abnormal phenomena, analyzed the reasons and presented the solutions. Time consumptions of communication blocks and digital IO blocks takes up a large proportion of simulation step time, which...
In Traditional process for solving performance parameters of fix-pad journal bearing, various formulas of eccentricity ratio and attitude angle are needed for different bearing types. A performance calculation model for all kinds of fix-pad journal bearing based on unified coordinate system is presented in the paper. With bearing center as the origin, this model establishes a unified coordinate system...
The paper presents nonlinear modeling study of belt conveyor system using the least square support vector machine (LS-SVM). Belt conveyor is a nonlinear, severe disturbance and time-varying system. So far, most of the existing models are based on mechanism laws, which are very useful for belt conveyor design. However, they are too complicated to be applied to control system design. To facilitate a...
This paper presents an improved cellular automaton model for symmetric two-lane traffic. Based on existing models, the modified model incorporates anticipation effects, sensitive driving technique and information interaction synthetically. Various empirically observed two-lane phenomena, like the meta-stable states, are reproduced in the modified model. An increase in traffic capacity is observed,...
In medical imaging research fields, three-dimensional (3D) shape modeling and analysis of anatomic structures with fewer parameters is one of important issues, which can be used for computer assisted diagnosis, surgery simulation, visualization and many medical applications. The 3-D object shape or surface can be expressed by spherical harmonics. In this paper, we present a spherical harmonics based...
This paper proposes a suboptimal nonlinear model predictive control (NMPC) algorithm based on Genetic Algorithm (GA). A nonlinear programming problem is solved online in NMPC. GA has been successfully applied to nonlinear programming problems where other decent-based methods have often failed. In this paper GA is used to optimize the control sequence per sampling time. In order to reduce the computational...
The prominent virtues of grey prediction are small information, few data and a little of computation. The conventional PID controller has strong robustness, sophisticated technology and simple structure, so it has been used widely in the process control. With the adjustable role of feedback response of biological immune systems, the capability of simulating non-linear functions with fuzzy rationalizing...
This paper deals with steering control problem of a computer simulated model car with fuzzy control approach. For simulating the real environment, the stochastic behavior of system is considered as multiplicative noise term. In addition, the external disturbance effect on system is also discussed for achieving attenuation performance by applying passivity theory. Through using the Takagi-Sugeno (T-S)...
The authors investigate cobweb type service price fluctuations with adaptive learning, and put forward a dynamic service pricing method based on the dynamic stochastic wealth model (DSWM). In this model, authors treat the service market as an expectation feedback system, where the current market equilibrium price of service determined by aggregated individual service providerpsilas expectations of...
