This article is based on a delay filter-x least mean square (DFxLMS) algorithm which considers secondary path as a delay and uses strong tracking filter (STF) algorithm to estimate the time delay parameter, in order to solve the noise elimination problem in active noise control (ANC) system. The key point of the proposed method is that the delay of secondary path can be seen as a state which can be...
Combined with the characteristics of this course and the authors' teaching experience, a teaching method that seeks to innovate in teaching objective, teaching concept, teaching content, and teaching resources is proposed in this paper after deep consideration into the necessity to conduct teaching reform in the era in which computer networks is highly developed.
Requirement modeling is an important procedure in software requirement engineering. Different from current requirement modeling methodology, this paper presents a new software behavior-oriented requirement description language-behavior description language (BDL) and a modeling methodology, and introduces a prototype system implementing the methodology. By using the modeling methodology, effective...
At present, vision-based illegally parked vehicles detection faces a range of issues such as narrowness of detection range, low detection precision and robustness. This paper proposed a technique for illegally parked vehicles detection. Firstly, Omni-Directional Vision Sensors (ODVS) are used to access Omni-directional images of the scene. Secondly, a method based on two backgrounds modeled by Gaussian...
Analysis model for routing protocols for wireless ad hoc networks is significant helpful, since it can be employed to investigate to highlight the most considerable ingredient, enlighten the heuristic approach, provide landmark for performance evaluations, and so forth. A fundamental issue in multicast over an ad hoc network is that what is the optimal multicast throughput in such an environment and...
