Analysis of the electricity consumption habits of users is of great importance in demand response based load management. Load identification is an effective approach to analyze the electricity consumption habits based on historical/real-time load data. A non-intrusive load identification method based on active load demand in a house/office environment is proposed in this paper. The aim of the method...
Based on properties of the Kalman filter, a distributed sensor placement method is proposed for output selection in a large scale networked system with sensor location constraints and/or performance constraints. This method only utilizes parameter matrices of the subsystem and its connection matrices with other subsystems to evaluate all the possible sensor locations of the large scale networked system...
Under the room temperature (293K) and nitrogen environment, the refractive index and absorption coefficient of the organophosphorus pesticide phosmet and hexachlorobenzene were measured by using the technology of terahertz time-domain spectroscopy within 0.3–2.3 THz. At the same time, density functional theory (DFT) was applied to calculate vibrational frequencies of the phosmet molecule and the hexachlorobenzene...
A novel capacitive power transfer (CPT) structure through self-capacitance routes is proposed in this paper. Selfcapacitance is the nature property of an isolated conductor which represents the amount of charges that have to be added to a conductor to promote its potential by one unit with respect to infinity. By utilizing the self-capacitance effects, one of the two coupling capacitors for conventional...
This paper proposes a novel algorithm to detect the community structure. Based on cascading failure model, the algorithm reveals the relationship between network nodes. Then, we exploited the k-nearest neighbors algorithm to transform the relationship between the nodes into European space, and quantitatively describe the close relationship between the nodes. Consequently, the network nodes will be...

For bridge structures, the influence of concrete creep will throughout the whole operation period, which reduces the beam stiffness and even result in brittle failure of structures. Creep is affected by many factors, and it is generally accepted that ambient humidity has significant effects on concrete creep and the properties of reinforced concrete structures. Therefore, it has important engineering...

And the nonlinear problem of hardware is solved by the using of inverse function in the system, which realizes the function of reactor variable power heating control and improves the test efficiency...
This paper studies the strategy consensus of cascading finite network games with the myopic best response adjustment rule. The main tool is semi-tensor product (STP) of matrices. Firstly, the cascading finite network game is converted into an algebraic form by using STP. Secondly, based on the algebraic form, two necessary and sufficient conditions are presented for the strategy consensus of the considered...
Microseismic monitoring technology has broad application prospects in large-scale civil engineering safety monitoring fields, such as tunnels. However, due to the lack of a perfect localization method, the microseismic monitoring system has the large localization error at present. To solve this problem, firstly, we preprocess the chaotic microseismic signal, using power spectrum analysis method to...

We propose a novel personalized recommendation model for social network users based on location computing. The novelty of our model is that we deal with the location based recommendation by combing logistic regression with collaborative filtering method. The logistic regression is used to train the weights of items' features, i.e., the recommendation sort list. On the other hand, the collaborative...
