This study aims to analyze the factors influencing the discontinuance intention of social music APP users, to help APP operators propose platform optimization solutions. Based on the Stimulus-Organism-Response (S-O-R) theory, this study constructs a model of the factors influencing social comparison, privacy concerns, information overload, function overload, anxiety, fatigue, and discontinuance intention. This study collected 393 valid questionnaires and used the structural equation model software PLS-SEM to examine the mechanisms of motivational factors on social music APP users’ anxiety, fatigue, and users’ discontinuance intention. This study found that internal motivation (social comparison, privacy concerns) and external motivation (information overload and function overload) influence users’ discontinuance intention through anxiety and fatigue. Social music APP operators need to integrate internal and external motivational factors to alleviate users’ anxiety and fatigue, to increase community user activity.

The rotating Rayleigh-Timoshenko beam element based on B-spline wavelet on the interval (BSWI) is constructed to discrete short shaft and stiffness disc. The crack is represented by nondimensional linear spring using linear fracture mechanics theory. The wavelet-based finite element model of rotor system is constructed to solve the first three natural frequencies functions of normalized crack location and depth. The normalized crack location, normalized crack depth and the first three natural frequencies are then employed as the training samples to achieve the neural networks for crack diagnosis. Measured natural frequencies are served as inputs of the trained neural networks and the normalized crack location and depth can be identified.

Sedimentology, geological modeling and prediction of the remaining oil distribution in a complicated fault-block reservoir in the Weicheng Oilfield, Dongpu Depression, China

Jinkun Yang,Weilu Li,Siyu Gao,Jinliang Zhang,Yi Zhang,Jiawei Lu 한국지질과학협의회 2019 Geosciences Journal Vol.23 No.5

Reservoirs in the Weicheng Oilfield, which occur in Paleogene Shahejie Formation Member 4 (Es4), were formed during the initial and strongly rifting stage of the Dongpu Depression. The geometry and distribution of sands of different types have controlled the heterogeneity of the reservoirs and have resulted in exploration challenges and relatively low recoveries. Based on various static and dynamic geological data including drilling, logging, seismic and production data, the microfacies features and distribution of Es4 were analyzed. Geostatistical three-dimensional (3-D) models and an integrated numerical simulation were constructed to quantify the geometry, spatial distribution and continuity of the reservoir sands and to predict the remaining oil distribution rules. Two depositional systems were recognized in Es4: terminal fans deposits in the lower part and partial shallow-lake deposits in the upper part. The three-dimensional geological model provided insights into the external and internal geometries, distributions and physical properties of the reservoir units. A sedimentary and connectivity feature analysis suggested four types of flow units: Type I units, which are primary sands of distributary channels and bars; Type II units, which are primary sands of proximal overbank and beaches; Type III units, which are sands of distal overbank; and Type IV units, which are mud flats and inter-beach-bar. The numerical simulation reproduced the changing process of the remaining oil, and the areas that have both high remaining oil saturations and reserve abundance, which are controlled by micro-facies and influenced by the structural trend and injection-production relations, comprise the key potential reservoirs: the sand pinch-out area, the imperfect pattern area and structural highs in Type I units and most of the areas in Type II units.

Nonlinear Dynamic Analysis of a Trochoid Cam Gear with the Tooth Profile Modification

Ronggang Yang,Bo Han,Jiawei Xiang 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.21 No.12

A trochoid cam gear (TCG) is a kind of precise transmission device with high performance, such as non-backlash, high precision, low noise, etc. Generally, the tooth profile modification technique is essential to influence the dynamic performance of TCG, which has not been studied. In the present, the equations of tooth profile modification are constructed to analysis the nonlinear dynamics of the TCG. Firstly, the tooth profile modification equation is deduced according to the requirement of meshing impact reduction. Secondly, considering the time-varying principal curvature radius of tooth profile and the nonlinear relationship between forces and deformations, a translation-torsion nonlinear dynamic model is established to further construct the nonlinear model of TCG. Finally, the dynamic characteristics of the TCG with three key parameters (the damping c , the radius d r of roller and the short amplitude coefficient K ) are investigated. The tooth profile modification technique proposed herein can improve the system stability. Moreover, by increasing c and K , or decreasing d r , the performance of TCG can be improved to maintain stable motion state.

No-backlash characteristics analysis of a cycloidal ball planetary transmission under axial pre-tightening

Ronggang Yang,Naige Wang,Jiawei Xiang 국제구조공학회 2022 Structural Engineering and Mechanics, An Int'l Jou Vol.81 No.4

Cycloidal ball planetary transmission (CBPT) has many applications as precision reducer, such as precision machinery and automation drive systems etc. The traditional analytical model of CBPT cannot accurately describe the change of the normal force of meshing points, and thus cannot describe the precise transmission process of meshing pairs. In the paper, a method for deriving the normal force equation is put forward by using the non-linear relationship between force and deformation in elastic mechanics. The two-point contact analytical models of all the meshing pairs are established to obtain the micro-displacement analytical model of CBPT under axial pre-tightening. Then, the non-real-time two-point contact analytical models of all the meshing pairs are further constructed to obtain the normal force expression to determine the critical compression coefficients. Experimental investigations are performed to verify the analytical model using the critical compression coefficients.

Clinical Significance of MRI Contrast Enhancement of the Oculomotor Nerve in Ischemic Isolated Oculomotor Nerve Palsy

Yan Yang,Chuntao Lai,Fei Yan,Jiawei Wang 대한신경과학회 2020 Journal of Clinical Neurology Vol.16 No.4

Background and Purpose Contrast enhancement of the oculomotor nerve in MRI was recently noticed in patients with clinical ischemic isolated oculomotor nerve palsy (iIONP). The opinions about whether this is a sign of inflammation and whether or not to administer steroids vary between doctors. The study aimed to determine the associations between this enhancement and vascular-disease risk factors (VRFs) and inflammatory factors in iIONP patients. Methods The study recruited patients who had experienced iIONP during the previous 2 years. They were divided into groups A and B based on whether or not they exhibited an enhanced oculomotor nerve in MRI of the cavernous sinus using thin-section, fat-suppressed, and contrast-enhanced sequences. VRFs, inflammatory factors, and improvement scores were compared between the two groups. Results Most (71.1%) of the 45 included iIONP patients had enhanced oculomotor nerves in MRI. VRFs, periorbital pain, elevated C-reactive protein and erythrocyte sedimentation rate, the neutrophil-to-lymphocyte ratio, and the platelet-to-lymphocyte ratio were not significantly associated with the enhancement. Four of the five patients in group A exhibited an elevated cerebrospinal fluid (CSF) IgG synthesis rate. The improvement score of eight patients who received 80 mg of methylprednisolone in addition to the routine therapy was not significantly different from the scores of the other patients (p=0.485). Conclusions More than half of the iIONP patients had an enhanced oculomotor nerve in MRI. A few of them also had elevated CSF IgG synthesis rate, but no further evidence for inflammation was found. The administration of steroids seemed to have no benefit other than increasing the blood glucose level.

Optimization Design of the Decentralized Multi-Vehicle Cooperative Controller for Freeway Ramp Entrance

Wang Jiawei,Ma Fangwu,Yu Yang,Zhu Sheng,Gelbal Sukru Yaren,Aksun-Guvenc Bilin,Guvenc Levent 한국자동차공학회 2021 International journal of automotive technology Vol.22 No.3

This research presents a multi-vehicle control strategy combining the merging control and platoon control to deal with the merging scenario in the freeway ramp entrance. In the merging controller, a selection algorithm is presented firstly to determine the merging sequence based on the initial states of the vehicles in the cooperative area. Subsequently, the optimized longitudinal trajectory of the facilitating vehicle and on-ramp vehicle is addressed by solving the Hamiltonian function. As for the platoon controller, string stability is analyzed to attenuate the impact of merging on the mainline traffic, considering the influence of communication time delay. Smooth mode switching is achieved by introducing the tracking policy of platoon controller to determine the terminal states of the facilitating vehicle. The proposed strategy is simulated at two typical merging scenarios, where two on-ramp vehicles attempt to cut into a six-vehicular platoon, to validate its feasibility and advantage.

Augmented RBF metamodel for global sensitivity analysis enhanced by recursive evolution LHD and efficient K-fold cross-validation

Guosheng Li,Jiawei Yang,Wenjie Wang,Zixuan Zhang,Weihua Zhang,Zeping Wu 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.8

This paper proposes an enhanced augmented radial basis function (eARBF) metamodel combining radial basis function and polynomial chaos expansions for global sensitivity analysis. First, the conditions required for the augmented radial basis function are constructed from the perspective of variance decomposition, after which the analytical expressions of the Sobol’ indices are deduced. To improve the generalization performance of ARBF, an anisotropic technique is proposed based on the local density of sample points. Furthermore, the recursive evolution LHD and efficient K-fold cross-validation method are adopted to reduce computational efforts. Five cases are presented to demonstrate the performance of the proposed approach. In all cases, eARBF yields satisfactory results with lower computational effort. The results indicate that the approach proposed in this paper is promising for GSA of engineering problems.
