Noise trausmissibility of mechanical systems in a submerged elastic shell

The Journal of the Acoustical Society of America (1986)

H. Huang Yipeng Wang

The effects of fluid-structure interaction on the force transmissibility of mechanical systems elastically mounted in a submerged elastic shell are investigated. An analytical solution for the ease of a harmonic-force-excited two-degrees-of-freedom undamped system attached inside a spherical elastic shell is obtained by the separation of variable technique. The transmissibility of the internal system is computed for a broad range of excitation frequencies and compared with that of the same system mounted on a fixed base. Due to the loss of energy through the radiation of the elastic shell, the transmissibility resonance peaks of the undamped system elastically mounted in the submerged shell are reduced to finite values and, for other nonresonance frequencies, the magnitude is in general also reduced. Moreover, the fluid-structure interaction effect shifts the peaks of the transmissibility towards lower frequencies. This information could be useful for the sound isolation of systems inside a submerged vessel.

Research on the evaluation system of smart tourism projects based on user experience

International Journal of Innovative Computing and Applications (2021)

Yipeng Wang

In recent years, with the rise of smart tourism, many tourist attractions invest a lot of money to build smart tourism projects to make tourism more intelligent. In order to evaluate the problems in the use of such projects and point out the direction of improvement, this paper proposes a smart tourism evaluation index system based on user experience. The evaluation index system probes into the actual feedback data of the users in the tour process from users' sensory experience, program experience, content experience and related experience. Then, the author utilise the fuzzy comprehensive evaluation method to process the collected data to obtain the evaluation index under the framework of the index system. In the application of this evaluation index system, it is compared with the commonly used evaluation index system in industry to point out the advantages and disadvantages of smart tourism projects and the direction of improvement more directly and effectively.

Foreign aid and income inequality: a quasi-experimental evidence

Applied Economics Letters (2023)

Xiuhua Wang Yipeng Wang Pei‐Chien Lin Ho-Chuan Huang

ABSTRACTABSTRACTThis article investigates the causal effect of foreign aid on income distribution. We rely upon the fact that, starting from 1987, eligibility for aid from the International Development Association has been according partly to whether a country' per capita income is below a certain threshold, enabling a regression discontinuity design. The empirical evidence demonstrates that for those countries receiving foreign aids, their income distribution is significantly improved. In addition, we show that foreign aid lowers income inequality possibly through boosting income shares held by the lower 80% at the expense of decreasing income share held by the highest 20%.KEYWORDS: Foreign aidincome inequalityregression discontinuity designfuzzyJEL CLASSIFICATION: C21C26D31F35 Disclosure statementNo potential conflict of interest was reported by the authors.Supplementary dataSupplemental data for this article can be accessed online at https://doi.org/10.1080/13504851.2023.2217557.

Bounds on the Average Recurrence Interval of Major Earthquakes Along the Haiyuan Fault In North-Central China

Seismological Research Letters (1988)

Zhang Peizhen Péter Molnár Zhang Weigi Qidong Deng Yipeng Wang

Abstract Evidence of surface rupture has been found in trenches near Caiyuan and Shaomayin along the Haiyuan fault, where a great earthquake occurred in 1920. In addition to the 1920 earthquake, faulting occurred at least once between 2590 ± 190 years and 1525 ± 170 years B.P. in Caiyuan, and there probably was another event since 1525 ± 170 years B.P. The formation and later tilting of fault-related, scarp-derived colluvial wedges in the Shaomayin trench appear to record the occurrence of two pre-1920 events in the last 2200–3700 years, but there could have been three or more events. The average recurrence interval for great earthquakes along the Haiyuan fault probably exceeds 700 years, for the 1920 Haiyuan earthquake is the only major event to have been reported in this area in as many years of recorded history. Using a Holocene slip rate along this fault of 8 ± 2 mm/yr, and 8 m as the average amount of offset associated with past great events that have been determined by our previous studies, the resultant earthquake recurrence intervals would be from 800 to 1400 years. The results from our trenches and the historic record are consistent with this range.

Bounds on the Holocene Slip Rate of the Haiyuan Fault, North-Central China

Quaternary Research (1988)

Zhang Peizhen Péter Molnár B. C. Burchfiel L. H. Royden Yipeng Wang

We measured the offsets of six stream valleys, of 30 to 90 m, along the northwest-southeast trending, left-lateral Haiyuan strike-slip fault, in north-central China. Minimum ages of these offsets were determined to estimate lower bounds for the Holocene slip rate. The most reliable bounds are 7.6 ± 1.0 and 6.7 ± 1.0 mm/yr, with three others that are smaller (3.4 ± 0.7, 3.5 ± 0.9, and 4.1 ± 0.4 mm/yr) and one large value (16.4 ± 5.9 mm/yr) that we doubt. Thus, the average Holocene slip rate of the Haiyuan fault is larger than 6 mm/yr and probably exceeds 7 mm/yr. If the average slip rate of 5 to 10 mm/yr for the Quaternary Period is applicable to the Holocene Epoch, the average rate is 8 ± 2 mm/yr.

Variations in the Geometry and Amount of Slip on the Haiyuan (Nanxihaushan) Fault Zone, China and the Surface Rupture of the 1920 Haiyuan Earthquake

Geophysical monograph (2011)

Qidong Deng Shefa Chen Song Fangnin Zhu Shilong Yipeng Wang

The Haiyuan earthquake (M = 8.7) of December 16, 1920, in China caused strike-slip displacement along 220 km of the Haiyuan (or Nanxihaushan) Fault Zone, which lies on the northeastern margin of the Qinghai-Xizang (Tibetan) plateau. The Haiyuan fault zone, which strikes 285°–295°, apparently became an active sinistral strike-slip during Pleistocene time. The fault zone is composed of at least eight major subparallel shear fractures, most of which are arranged in a left-stepping pattern, and as many as six pull-apart basins have formed in the central segment of the fault zone. River systems of different ages have been sinistrally offset different amounts. Variations in the sense of vertical motion have occurred along segments of the fault, and pull-apart basins are commonly associated with the areas where normal components on subparallel segments prevail. Relatively young faults with oblique normal slip strike parallel to the overall trend of the fault zone and intersect the major subparallel shear faults with acute angles (10 to 15°). The earthquake fault of 1920 caused slip along the major strike-slip fault segments and along oblique normal faults within pull-apart basins. Thus segments with pure strike-slip and with oblique normal slip, were activated in 1920, each with different surficial features and with different amounts of slip.

Construction method and application of real‐time monitoring and early‐warning model for anaerobic reactor leakage

Process Safety Progress (2020)

Feng Wang Fujie Deng Yipeng Wang

Abstract The anaerobic reactor is one of the most critical reaction devices for biogas engineering, wherein is usually a large amount of flammable gas methane. Fire and explosion accidents will be easily triggered if the gas leaks, threatening the surrounding buildings, equipment, personnel, and so forth. Avoiding the significant accidents caused by CH 4 leakage has become a critical issue in the design and condition monitoring for an anaerobic reactor. This article presents a model construction method for leakage early‐warning. Incident database and hazard and operability analysis (HAZOP) can be utilized to identify the leakage risks, and computational fluid dynamics (CFD) simulation and consequence quantity calculation can be used to determine the consequence influence ranges. The calculation results can be employed to establish prediction models for abnormal situations. Process safety management (PSM) data and risk analysis results can be combined with the possible abnormal situations to assist operators in adopting the right solutions. An early‐warning system has been developed to illustrate the industrial application of the model. It can be concluded that collecting multi‐parameter values according to the real‐time changes in the actual production process, continuous monitoring and early‐warning of leakage risk, and so forth, will contribute to accident avoiding and emergency response in reactor operations.
