Aggregated Electric Water Heaters (EWHs) are ideal candidates for demand response (DR) resources considering that EWHs account for a huge percentage of energy consumption among all the home appliances and their heat storage capability. Power system reliability could be affected by the power consumption pattern of massive households. In this paper, a Binary Particle Swarm Optimization (BPSO) algorithm...
Predicting the High Intensity Radiated Field (HIRF) coupling in complex system is highly required in the aeronautic industry, which can be performed by electromagnetic simulation. But the validation of electromagnetic simulation is a difficult issue which needs proper flowchart and validation methods. In this paper, the numerical simulation by the parallel Finite-Difference Time-Domain (FDTD) method...
For the flotation process, the control target is not only to control the slurry level and pulp flow to track the set-points of the slurry level and pulp flow, but also to make the concentrate grade and tail grade within the target range. In order to achieve this goal, firstly, the model of the lower layer and the upper layer are established respectively; secondly, a multivariate PI controller is applied...
Advances in nanotechnology have made it possible to engineer nanomachines. Single nanomachine has limited abilities to accomplish target goals, so a nanonetwork, which is composed of interconnected nanomachines, is expected. To perform cooperative operations, the synchronization of the nanomachines is essential. However, one of the main challenges in synchronizing the nanomachines is the study and...
As the rapid growth of smart phones, dense and large-scale 802.11-based WLANs have become an important infrastructure to the Mobile Internet. Usually, mobile devices perform periodic scan to collect the information of surrounding APs for awareness of wireless environment. However, this kind of frequent scan severely degrades both the performance of network and client. In this paper, we first collect...
Molecular communication is a novel approach for conveying information at the nano- or micro-scale. The modulation and demodulation schemes for fixed transmitter and receiver nanomachine have been studied in previous literatures. However, it is a big challenge to perform the demodulation when the transmitter/receiver is mobile. The bit symbol will not align due to the movement of the transmitter/receiver...
As 802.11 network has become an important infrastructure for the Mobile Internet, the performance of WLAN handoff is critical to the quality of user's experience. Although it has shown that there are a large number of invalid handoffs in large-scale 802.11 networks with dense AP, the reason and seriousness still remain unclear. In this paper, we propose HandoffAnalyser, a client-network collaborative...
Cloud computing is a type of Internet-based service computing that provides computing, storage and networking services to multiple users. With the increase of data size, computing capacity runs out quickly in cloud computing services. To fill the shortage of computation capacity, we propose to adopt variable precision by implementing unum (universal number), which is a number format different from...
As the rapid growth of Wireless Local Area Network (WLAN), the densities of both Access Points (APs) and clients have dramatically increased. In the dense and crowded WLANs, the challenges of load balance become non-negligible due to the problems raised by traditional AP selection mechanism based on signal strength. To address this issue, many existing works consider the load metrics and conduct dynamic...
For many industrial applications, upgrading the machine performance by changing the rotor structure while keeping or slightly modifying the stator structure is an economic and effective solution for complying with the existing production line. Electromagnetic torque is always one of the key factors that need to be evaluated. An intuitive and universal approach applying the same principle for torque...
The SKA (Square Kilometer Array) radio telescope under construction will become the largest telescope in the world by integrating the sampled data from a huge number of small antenna nodes in the array to emulate a giant antenna. Due to the limited storage space, the SKA needs to process massive data in real-time, which makes the SKA scientific data processing become a bottleneck of the computational...
With the rapid growth of Mobile Internet, supporting different Qos for a variety of mobile applications becomes a great challenge in wireless network more and more. SDN providing huge flexibility on IP stream management in wired networks motivates considerable works on extending SDN to wireless network, but most of them are mainly focused on wireless resource abstraction and management. Different...
Objective Generalized anxiety disorder (GAD) is the most common anxiety disorder in primary care. The clinical studies on anxiety disorders have been commonly conducted, however the efficacy of acupuncture in treating GAD is uncertain. We therefore performed a systematic review to evaluate the evidence regarding acupuncture for GAD. Data Sources CBM, CAJ, CSJD, CNKI, WanFang, EMBASE, Pubmed/MEDLINE,...
Objective: To excavate the main acupoints selection for cervical radiculopathy by using statistical methods and data mining methods. Methods: CNKI, CBM, Wanfang, VIP were searched for literature published from 1978-2016. Descriptive analysis, association rules analysis was made by SPSS 17.0 software. Results: The top 5 meridian with the highest frequency of application were Du meridian, Large intestine...
Civil aviation enterprises consider emergency response efficiency as a very important factor in order to cope with all kinds of incidents. This paper proposes capability evaluation system of civil aviation emergency management to measure the emergency response efficiency, which includes 11 factors during four emergency management stages. The 11 factors include organization, response plan, risk management,...
Today's Internet mobility management is facing great challenges to satisfy the requirement of scalability and flexibility, such as heavy signaling overhead, data traffic centralization, etc. In this paper, some mobility management design principles concerning the trend of large-scale and high-density wireless network are given. A mobility management scheme is proposed according to these principles...
This paper introduces a new application of moulding technology to the installation of ferrite magnet material into the rotor flux barriers of Ferrite Magnet Assisted Synchronous Reluctance Machine (FASynRM). The feasibility of this application with respect to manufacturing process and motor performance has been demonstrated. In comparison to the conventional ferrite magnet installation approach, moulding...
Hyperspectral images (HSIs) exhibit a limited number of labeled high-dimensional training samples, which limits the performance of some classification methods on feature extraction or feature reduction. Efficient classification techniques are desirable solutions to this problem. In this paper, we propose a supervised method based on the PCA network (PCANet) and Gaussian weighted SVM (Gaussian-SVM)...
In this paper, a active and passive microwave sensing combing algorithm is proposed, which merges L-band radiometer data and L-band radar data to obtain high-resolution soil-moisture in the premise that the soil roughness effect is not considered. The algorithm uses single-frequency single-incident angle measurements, considering effect of vegetation index (VI), establishs the relationship between...
With the reduced cost of launching a satellite and the development of satellite communication technology, satellite networking is regaining people's focus both from industry and academia. Among them, GEO satellites, with the benefits of large and stable coverage area, have already been used for commercial broadband communication. However, the inherent long transmission range makes the propagation...
