While Peer-to-Peer (P2P) lending is rapidly growing, it also accompanied by high credit risk due to information asymmetry. Besides conventional hard information, soft enters into the decision process. The descriptive loan texts submitted borrowers have great potential for exploiting useful factors, but pose challenges semantic sensitivity context and complexity of content representation. We propose a novel text mining method automatically extracting factors from texts. maps terms an...

Persistent type 2 endoleaks (pT2ELs) require long-term follow-up to prevent life-threatening complications. This study aimed create a model predict the outcome of pT2ELs after endovascular abdominal aortic aneurysm repair (EVAR) using deep learning (DL). We retrospectively reviewed 94 patients with treated between January 2010 and December 2019 at Zhongshan Hospital Fudan University. The median was 38.2 months, 21 (22.3%) had pT2ELs-related severe adverse events (SAEs). ITK-SNAP software...

For the LCL-type grid-connected inverter, grid voltage full feedforward scheme is an effective method to improve quality of injected current. However, in applications where a step-up transformer adopted and its leakage inductance serves as grid-side inductor, it difficult directly measure voltage. this case, capacitor feedback proposed article suppress current distortion due harmonics, function includes proportional, derivative, second-derivative components. It found that derivative...

A dielectric resonator antenna (DRA) is placed on top of a slotted cavity to form hybrid dual-band antenna. The zonal slot cut onto the fed by an embedded L-probe, whereas DRA coupling rectangular face cavity. It found that resonance frequencies and are primarily dependent DRA, respectively, which greatly facilitates design. To demonstrate idea, proposed designed for IEEE802.11a/b WLAN applications. reflection coefficient, radiation pattern, gain studied, simulation measurement in reasonable...

Reviews posted to social media are an effective source of information for helping quality managers improve product quality. However, because helpful quality-related reviews may involve various aspects quality, previous studies confusing these cannot provide targeted regarding different and production system improvement. In this paper, we propose a method multi-class classification corresponding systems. Furthermore, the efficient accurate identification remains critical challenge sparseness...

Modular multilevel converter (MMC) is a possible solution for integrating an electric vehicle (EV) fleet into the smart grid. Considering differences of initial state charge (SOC) and inherent randomness in charge/discharge demands from various EVs connected to MMC, it becomes challenging control MMC order satisfy network EV requirements. This paper proposes multi-objective power management strategy MMC-Based be integrated grid using virtual SOC model coordinated flow among arms same...

A zonal slot antenna cut onto a conducting cavity is combined with dielectric resonator (DRA) to form circularly polarized (CP) dualband hybrid antenna. The and DRA are located on the side wall top face of cavity, which responsible for lower upper bands, respectively. No external ground planes used and, thus, structure very compact. An L-probe placed inside feed directly excite indirectly through cross coupling beneath DRA. In this paper, two symmetrical cuts exciting CP fields, third...

Friction pendulum bearing (FPB) shows superior performance in reducing dynamic responses of structures under earthquakes. Though the seismic response FPB-isolated structure is well understood, its overturning resistance caused by limited permissible displacement impact rarely studied. This paper presents an evaluation and parametric study on impact, using particularly coefficient to evaluate isolated structure. The capacity as when subjected pluse-like no-pluse-like earthquake records were...

Accurate forecasting of short-term wind speed is a key technology to enable efficient and reliable operation microgrids with generators. Results prediction (WSP) methods in the current literature are subject errors due random nature limited generalization forecast algorithms. In this paper, WSP method based on model forecast, error correction, power generation, support vector machines (SVMs), algorithms proposed. proposed method, built predict original predicted speed. Subsequently,...

To have a better understanding of the torsional mechanism and influencing factors PC composite box-girder with corrugated steel webs, ultimate strength four specimens under pure torsion were analyzed Model Test Method. Monotonic acts on by eccentric concentrated loading. The experimental results show that cracks form at an angle <TEX>$45^{\circ}$</TEX> to member's longitudinal axis in top bottom concrete slabs. Longitudinal reinforcement located center cross section contributes little...

Social media provides customers with platforms on which to express usage experiences, opinions, preferences and expectations of product quality. Thus, a large number reviews available social become an effective information source for quality management. In this study, we attempt identify that are helpful from the perspective total management, called Helpful Quality-related Reviews (HQRs). First, propose definition taxonomy HQRs based attractive theory. Then, construct Review Identification...
