One-Class Collaborative Filtering (OCCF) is an emerging setup in collaborative filtering which only positive examples or implicit feedback can be observed. Compared with the traditional setting where data has ratings, OCCF more realistic many scenarios when no ratings are available. In this paper, we propose to improve accuracy by exploiting rich user information that often naturally available community-based interactive systems, including a user's search query history, purchasing and...
This paper addresses the adaptive synchronization for uncertain Liu system via a nonlinear input. By using single controller, approach is utilized to implement of with total parameters unknown. method simple and can be easily designed. What more, it improves existing conclusions in Ref [12]. Simulation results prove that controller effective feasible end.
Supplement 23 to DICOM (Digital Imaging and Communications for Medicine), Structured Reporting, is a specification that supports semantically rich representation of image waveform content, enabling experts share related patient information. SR the textual coded data linked images waveforms. Nevertheless, medical information technology community needs models work as bridges between relational model open object-oriented technologies. The authors assert representations Reporting standard, using...
This paper presents a modern probabilistic reliability assessment method that includes the modeling of substation configurations and simulation breaker switching operations in response to equipment failures evaluation transmission grid reliability. Such features are not generally available conventional power flow analysis tools. The has been applied study two 500 kV substations East China system as part development along-term expansion plan for EHV grid. first stage is assess impact layouts...
Nowadays the Web is being increasingly deepened by a large group of online databases. How to map uniform query corresponding database exactly critical problem integrate deep databases in same domain. The attribute may have different ranges forms, which means mapping it becomes bottle-neck solve form problem. We use fuzzy synthetic evaluation this Firstly, we analyze issue, point that data range key problem, and transfer function compute membership ranges. Then select optimal result. To...
Abstract In the current information society, dissemination mechanisms and evolution laws of individual or collective opinions their behaviors are research hot topics in field opinion dynamics. First, this paper, a two-layer network consisting an individual-opinion layer collective-opinion is constructed, model incorporating higher-order interactions (i.e. OIHOI model) proposed. Furthermore, dynamic equations for both individuals groups presented. Using Lyapunov’s first method, two...
One of the most challenging issues service-centric software engineering is automatic composition services. In academia, approaches reduce service problem to AI planning and generate a plan for user's request from scratch. However in real world there may be large amount same or similar requests, so how adapt existing solutions past requests functionally fit current ones becomes new challenge context semantic Web our study, we propose an approach automated services based on case-based...
This paper is concerned with the finite-time stochastic synchronization of a chaotic system without linear term and its application in secure communication based on synchrosqueezed wavelet transform (SWT). In order to improve anti-jamming ability systems forecast time, proper controllers are designed achieve for random perturbation. Based proposed systems, we present scheme about secondary encryption enhance level security. Moreover, novel SWT algorithm introduced correctly recover...
In order to avoid conservative results, when calculating the ability of power system accommodate renewable energy, social data need be integrated. Data cleaning is an important step in integration. Traditional methods rely only on and ignore implicit rules. This paper first analyzes requirements for energy accommodation, then proposes a technology. technology digs out associations between data, converts them into fuzzy rules form Probabilistic soft logic (PSL), builds neural network based...
The synchronisation problem of Lorenz system is further investigated in this paper. On the basis Lyapunov stability theory, some simple and useful criteria for to be delay-independent asymptotically stable are presented via combining drive Delayed Feedback Control (DFC) methods. Especially, only one controller needed obtain asymptotically. Theoretical analysis numerical simulations show effectiveness feasibility proposed schemes.
In recent years, the global climate has changed significantly, extreme weather increased, and lightning activities have become more frequent intense. How to predict activity in area covered by transmission line is key achieve effective protection power grid. Firstly, a nonlinear correlation model between meteorological information including temperature, precipitation, atmospheric pressure, wind direction, speed humidity attributes was established based on Bayesian network. Then quantitative...
Abstract The Song-era artifacts carry ideas of naturalness and moderate elegance, preserving passing them on to future generations. emerging digital opportunities initiatives allow us not only study pattern samples in detail but also create equivalents that are subject aging or destruction. This research aims obtain specific knowledge situational experience regarding the digitization Song Dynasty patterns. At preliminary stage, authors performed an online survey a popular Chinese platform....
Due to the various characteristics of smart substation, such as digitization, integration, low carbon and environmental protection, it has been widely used in recent years. But because its excessive reliance on network communications, many accidents substation secondary system have occurred. In this paper, an on-line monitoring accident inversion scheme is proposed, which could be judge health status before occurs. The research result paper can realize pre-accident warning, evaluation,...

Controlling negative sequence currents at zero is feasible in practice, which can improve the performance of voltage-source converters (VSCs) during asymmetric ac faults. VSCs are usually synchronized with grid via phase-locked loop (PLL) However, synchronization stability affected by current VSCs. Hence, this article analyses PLL transient PLL-synchronized single-phase-to-ground fault. The parametric impacts and effect positive/negative on revealed analytically, employing phase portrait...
