In this paper, a video vertical search engine is designed and implemented based on the theory of vertical search engine. Firstly, we introduce the vertical search engine and its research situation at home and abroad, analyze the principle of implementing the vertical search engine, and introduce the key technology used in this paper, such as subject information acquisition method, Chinese segmentation...
Study on energy consumption in wireless systems becomes attractive recently. The worldwide organization 3GPP has established a series of standards to help reduce energy consumption in wireless systems. However, the utilization of green related techniques is still in theoretical way. To reduce energy consumption in cellular networks, the effective and common method is to shut down idle base stations...
An Active Disturbance Rejection based solution is proposed for the position control of a standard inverted pendulum system, demonstrating a largely model independent design that is distinctly different from existing model-based designs from classical as well as modern control theory. The quality of the control loop is further improved with a unique double disturbance observer design, which rejects...
As the flight scheduling has always been a key technology which reduces flight delays and costs. Rational and efficient flight sorting method not only can effectively improve the utilization of the airport, reduce flight delay, but also ensure flight safety and reduce the incidence of sudden accidents. Firstly, we studied the application of ant colony algorithm in flight sorting, and proposed a new...
To improve comprehensive performance of denoising range images, an impulsive noise (IN) denoising method with variable windows is proposed in this paper. Founded on several discriminant criteria, the principles of dropout IN detection and outlier IN detection are provided. Subsequently, a nearest non-IN neighbors searching process and an Index Distance Weighted Mean filter is combined for IN denoising...
Traditional Chinese medicines (CM) topical herbs for atopic dermatitis are mainly consist of nourishing the blood, dryness-moistening, dry-dampness, skin-moisturizing and itching-relief, of which therapeutic principles are taken as dryness-moistening to relieve itching. Based on the modified mutual information, complex system entropy cluster and unsupervised hierarchical clustering, the CM recipes...
In ITS model (Intelligent Tutoring System), student model plays a significant role and its intelligence mostly decides the quality of the whole system. Various theories have been put forward to implement student modelling. On the basis of previous experiments' results, this article introduces a new quantifiable model to record and reflect students' learning processes and results. It is named the CMA...
This study extends Sheng-Jie Yang's study [5] and process long-term experiment, on the other hand, we don't have to force students to use any reading strategies because we want students to study by themselves. We investigated in detail the users' demand and using timing on visual cue map. At the end of semester, we present the final system through interviewing students for improving the visual cue...
Accelerometers-based devices provide a convenient and efficient way to measure the physical activity, but they are not convenient enough for general users. To improve the ease of use, we developed a novel accelerometer-based cloud-computing system that can automatically upload the recorded acceleration data by telemetry to a cloud end server for further analysis. This automatic cloud computing actimeter...
Model checking provides a way to automatically verify hardware and software systems, whereas the goal of planning is to produce a sequence of actions that leads from the initial state to the desired goal states. Recent research indicates that there is a strong connection between model checking and planning problem solving. In this paper, we investigate the feasibility of using different model checking...
In the oil industry, it is important to measure gas/oil/water flows produced from oil wells. To determine gas and oil production, it is necessary to measure the water-in-liquid ratio (WLR), liquid fraction and some other flow-rate related parameters. A research team from The University of Manchester and Schlumberger Cambridge Research Ltd have developed a non-radioactive gas/oil/water flow experimental...
Annotation is a frequently used learning skill. When taking note, the reader only focuses on partial content of a topic or a segment. The note would be non-organized and piecemeal. Therefore, the relationship between topic and annotation would be lost or indirect including the relationship among annotations. Thus, because of the dispersion of annotations, readers would lose the structure of the content...
Customer needs is always a hot topic in the marketing area. Under the force of competition, it is necessary for the companies to grasp the real customers needs After reviewing the classic theory models about customer needs, including Maslow hierarchy of needs theory, Herzberg's two-factor theory, McClelland Achievement Motivation Theory and Kano model, this study focuses on how customer service needs...
Model checking provides a way to automatically verify hardware and software systems, whereas the goal of planning is to produce a sequence of actions that leads from the initial state to the desired goal state. Recently research indicates that there is a strong connection between model checking and planning problem solving. In this paper, we investigate the feasibility of using a newly developed model...
A novel framework for 3D freehand tracking is put forward in this paper. Firstly, we model and investigate this problem under our virtual assembly system (VAS), so as to decrease the arbitrariness and complexity of this issue. Secondly, we put emphasis on building cognitive and behavioral model (BM) for users in VAS. Thirdly, we research on the way to track 3D freehand based on BM. Our experimental...
Traffic signal control is a challenging task for traffic systems. As fuzzy logic is proved to be well suited to control some complex systems with uncertainties and human perception, it has been widely used to control the traffic signal in recent years. This paper proposes a novel fuzzy logic controller for signalizing modern roundabouts. Different from existing fuzzy traffic-signal controllers, the...
Bridge health monitoring system (BHMS) is able to simultaneously get all kinds of information which reflect the safety conditions of bridge structure, and provide scientific proof for the analysis of bridge health. At present, the BHMS developed only for specific bridge or several long span bridges, and the monitoring information is not shared as a single island, there is also not have a unified and...
With the large enrollment of postgraduate students, many questions related with the students' education has appeared. This research takes X university as a case for the graduate satisfaction survey. During the case study, we detect that graduate students have low satisfaction in “tutor system”, “curriculum system”, “teaching situation” and “academic environment”. Therefore, we propose that instruction...
Current operational implementations of 4D-Var rely on the assumption that the numerical model representing the evolution of the atmospheric flow is perfect, or at least that model errors are small enough to be neglected compared to other errors in the system. Weak constraint 4D-Var with a model error forcing control variable has been implemented and tested within the YH4DVAR system in this paper....
The traditional theory of annuity demand thought a life-cycle consumer who pursued the maximization of consumption utility should fully annuitize all of their savings. The phenomenon that their theoretic conclusion does not accord with the reality was called “annuities puzzle”. Establishing a savings expected utility model that involves term insurance, annuity and security, we discuss the optimal...
