Wang Yuanqi and the orthodoxy of self-reflection in early Qing landscape painting

Wang, Shen University of Pennsylvania 2010 해외박사(DDOD)

This dissertation explores the life and art of Wang Yuanqi (1642-1715), one of the most influential literati artists of the Qing Dynasty (1644-1911). As a representative of the so-called "Orthodox Painting School," Wang considered himself the heir to the genuine thousand-year-old tradition of Chinese painting. Throughout his lifetime, he made every effort to establish and consolidate the authority of his school of painting. Since his early years, he had been trained as a traditional Chinese literatus. Under the direct supervision of his grandfather, he practiced landscape paintings in the style of ancient masters, especially that of the Yuan literati painter, Huang Gongwang (1269-1354). However, he was never satisfied with the facsimiles of the old masterpieces. Beyond his models, he created new theories of composition and brushwork; he introduced a new style of light color landscape with unique techniques. Moreover, benefiting from the lenient cultural policies of the Kangxi emperor (r. 1661-1722), he successfully led a movement of canon-formation in artistic circles. The research of this thesis is based on three types of sources: (1) Wang Yuanqi's published writings, (2) his paintings, and (3) publications and manuscripts by Wang's contemporaries. Different from previous scholarship which mainly focuses on the classicism of Wang Yuanqi's work, this dissertation provides a comprehensive study of Wang's life and his circle and investigates the reason and procedure of the rise of the Orthodox Painting School in the early eighteenth century.

Abstract A Study of the Composing Skill and Score Structure in Zhou Long's Orchestral Music -- Centred on ‘Daqu’, ‘Four Tang Poems’, and ‘1911 Overture’ Supervised by Prof. Woo-Chang Lee Yanbing Wang Major in Composition Graduate School of Applied Arts Department Zhou Long is one of the most distinguished contemporary composers. As a Chinese composer, Zhou embodies the pursuit of Chinese traditional culture in his composing concept, and expresses it through his exquisite composing skills. The unique composing style makes Zhou world-famous as a Chinese composer, which has inspired a new generation of music composers. This dissertation takes Zhou Long’s orchestral works Daqu, Four Tang Poems and 1911 Overture as the research objects, analyzes the composing skills like music material, timbre, sound pattern, pitch organization and structure arrangement from the perspectives of Guqin music material, poetic music performance and the Peking Opera art elements, probes into the music language of the orchestral works, and on this basis, discusses the performance of Chinese traditional culture in the works above. The dissertation is composed of three parts: introduction, main part and conclusion. Chapter one is a brief introduction to Zhou Long’s international influence, his main achievements, the composing background of his orchestral works – Daqu, Four Tang Poems and 1911 Overture, the research objectives, methods and the research background. In the main part, the author firstly analyzes the music language, music material sources and their representation forms in Zhou’s orchestral works, are explored by analyzing the music language of his orchestral works; secondly analyzes the timbre, the sound form and sound modelling involved in the Guqin music and poetry representation in his works and their influence in the overall sound tension; and thirdly analyzes the use of traditional music elements in the pitch and structure in Zhou’s works, and summarizes the cross-cultural fusion and aesthetic orientation. The last chapter is Conclusion, which is a summary of Zhou Long’s orchestral works on the basis of deep analysis above. Zhou Long is famous contemporary composer living in America. The composing skills and music thought in his orchestral works – Daqu, Four Tang Poems and 1911 Overture exhibits the excellence of the fusion of contemporary Chinese and western arts. The most outstanding of all in his works is the use, quotation, assimilation and absorbing of traditional Chinese music elements, and this is used to set off the musical imagery, and thus, to realize the virtual clashing and fusion of Chinese and western culture, and traditional and contemporary culture. As for the imagery presented, the composer makes a deep analysis of the Chinese traditional poetry and use the imagery in it into the musical composing process; as for the orchestra compilation, it is not merely a simple mixture of the full use of Chinese and western musical instruments; as for the composing skills, the composer absorbs the music material form the traditional folk, and connects it with the western modern music composing skills, and makes any single sound with the cavity features, and thus the treated sound may drift between sound image and meaning imagery, which exhibits a strong Chinese traditional music feature. Then, it comes to the change of instrumental performance by introducing western tablature, which means to use the western stringed instruments to simulate Chinese national musical instruments, and to make the music to present traditional Chinese charm. As for the score structures, the composer uses the principle of structural variable speed in traditional music composing to organize the structure in his own works, and makes appropriate adaptations on the basis, and makes a blending of the western music composing principles of juxtaposition, convolution, and representation so as to better fit the development of the musical contents. Zhou Long has accumulated a great number of musical works during his lifetime with a wide range of styles. Each of his works exhibits its unique artistic charm. However, what remains to be interlinked is the artistic concept behind his composing, which presents Zhou Long’s heartfelt salute to the traditional music culture and even to the traditional Chinese culture.

Influence of silicate modified expansion agent on engineering performance of ultra-high-strength concrete

Wang, Yi-Sheng 강원대학교 대학원 2022 국내석사

At an early age, ultra-high-strength concrete (UHSC) exhibits a large autogenous shrinkage, which easily leads to matrix shrinkage and cracking. This poses a significant threat to the service life of a building structure. In this study, the effects of silicate modified expansive agents (SMEAs) on the engineering performance of UHSC were systematically investigated. The compressive strength, ultrasonic pulse velocity, and surface resistivity were determined. Moreover, Heat of hydration, TG, Fourier transform infrared spectroscopy (FTIR) and other microscopic analyses were used to characterize the chemical composition of the UHSC. It can be seen from the test results that the compressive strength of UHSC tends to decrease with the increase of SMEA addition. The results of TG, X-ray diffraction, and other microscopic analyses indicated that the main composition of the UHSC was a mixture of calcium (aluminate) silicate hydrate, calcium hydroxide, and ettringite.

A Minkowski-type inequality for hypersurfaces in the Reissner-Nordstrom-anti-deSitter manifold

Wang, Zhuhai Columbia University 2015 해외박사(DDOD)

We prove a sharp Minkowski-type inequality for hypersurfaces in the n-dimensional Reissner-Nordstrom-Anti-deSitter (AdS) manifold for n ≥ 3. This inequality generalizes the one for hypersurfaces in the uncharged AdS-Schwarzschild manifold proved in [5]. With the Minkowski inequality, we prove a charged Gibbons-Penrose inequality for a large class of (n - 1)-dimensional spacelike surfaces in the Reissner-Nordstrom spacetime. [5] S. Brendle, P.

Economic Analyses of Business Decisions, Environmental Sustainability, and Policies

Wang, Yanbing Purdue University ProQuest Dissertations & Theses 2017 해외박사(DDOD)

This dissertation investigates the interactions among business decisions, the environment outcomes of such decisions, and environmental policies. In three essays, I address two topics regarding decisions by industrial firms and agricultural producers and the environment. The first two essays are concerned with environmental self-regulation of public firms, in which I explore the potential for financial incentives to motivate voluntary environmental abatement in the short run and the long run. In the third essay, I investigate the impact of energy policies on agricultural producers' planting decisions. The first essay addresses the financial incentives driving firm disclosure of positive environmental information and the link to environmental outcomes. I classify positive environmental disclosure by informational content, and find that forward-looking announcements and recognition by a third party bear the largest financial incentives, though only the latter has a discernible link to environmental outcomes. Beyond valuing firm financials, the stock market values firm social, environmental, and corporate governance performance as a whole. The results identify third-party recognition as a channel through which environmental information may induce self-regulation. The second essay investigates the long-term financial incentives of corporate environmental responsibility by examining whether an environmentally responsible firm benefits from a lower cost of equity capital, focusing on a particular channel: sustainable and responsible investing (SRI). Using treatment effect models, I test whether investments from SRI mutual funds with environmental screening criteria impact firm cost of equity capital. The results indicate that accounting for interactions between firms and non-shareholder stakeholders and potential agency costs associated with certain environmentally responsible activities of the firm, SRI investing can facilitate the alignment of firms' environmental and financial goals. In the third essay I assess corn planting decisions of agricultural producers in response to the increased spatial competition among ethanol plants in the Midwestern United States, following the energy policies that mandate the use of renewable fuels. I develop a spatial competition model which yields an index of spatial competition that incorporates determinants of local corn prices: the number of plants, distance between competing plants, and production capacity in local ethanol markets, considering three types of market structures: monopsony, duopsony, and oligopsony. I find that a change in the distance between two competing ethanol plants, a plant's own capacity, and a competitor's capacity all influence a plant's intensity of spatial competition. Econometric analyses further show that the intensity of spatial competition has a positive and significant effect on corn production.

Engineering Clostridium Saccharoperbutylacetonicum for Enhanced Isopropanol-Butanolethanol (IBE) Production from Lignocellulosic Biomass Through Acetic Acid Pretreatment

Wang, Pixiang Auburn University ProQuest Dissertations & Theses 2018 해외박사(DDOD)

The objective of this study was to achieve efficient biofuel production from lignocellulosic biomass through the development of a novel biomass pretreatment method in combination with the metabolic engineering of microbial strains for efficient conversion of biomass feedstock. First, an innovative biomass pretreatment method was developed using acetic acid (AA) as the treatment reagent considering its various advantages compared to the conventional dilute acid pretreatment method and the benefit of AA for biobutanol production; then, the hyper-butanol producing strain Clostridium saccharoperbutylacetonicum N1-4 was engineered for enhanced acid re-assimilation and acetone-butanol-ethanol (ABE) production from the acetic-acid-pretreated biomass; further, C. saccharoperbutylacetonicum was engineered for enhanced production of isopropanol-butanol-ethanol (IBE; which can be used directly as a fuel source rather than ABE) from the acetic-acid-pretreated biomass.For the biofuel production from lignocellulosic biomass, most biomass pretreatment processes need to use some chemical reagent as the catalyst to overcome the biomass recalcitrance barrier. Such reagents are usually severe inhibitors for the subsequence fermentation process. Therefore, in many cases, the liquid prehydrolysates fraction (LPF) after the pretreatment is discarded, which is a tremendous wasting of materials and leads to additional pollution. Biobutanol produced from ABE fermentation process has been of great interests recently due to its high value as a biofuel or biochemical. During the ABE fermentation, AA is produced and then re-assimilated as a carbon source. Thus, AA is a substrate rather than an inhibitor for biobutanol production. In this study, we employed AA as the chemical catalyst for the pretreatment of switchgrass which then be used for ABE production through simultaneous saccharification and fermentation (SSF) with hyper-butanol producing C. saccharoperbutylacetonicum N1-4. Through systematic investigation of pretreatment conditions and fermentation, we concluded that the pretreatment with 3 g/L AA at 170 oC for 20 min is the optimal conditions for switchgrass pretreatment leading to efficient biobutanol production. Both LPF and solid cellulosic fraction (SCF) of the pretreatment biomass are highly fermentable. In the fermentation with the LPF/SCF mixture, 8.6 g/L butanol (corresponding to a yield of 0.16 g/g) was obtained. Overall, here we demonstrated an innovative biomass pretreatment strategy for efficient carbon source utilization and biobutanol production.ABE fermentation generally has two phases: in the acidogenesis phase, fatty acids (acetic acid and butyric acid) are accumulated, while in the solventogenic phase, fatty acids are re-assimilated and converted into solvents. Therefore, the improvement of acid re-assimilation capability in the Clostridium host can possibly enhance the solvent production. In addition, acetic acid is often a significant component in the biomass prehydrolysates after pretreatment (especially when acid-based biomass pretreatment approach is employed). Thus, the enhancement of acid re-assimilation in Clostridium has practical significance for biofuel production from lignocellulosic biomass. Here, we overexpressed key genes of the ABE fermentation pathways in C. saccharoperbutylacetonicum to enhance the acid re-assimilation and solvent production. First, the native sol operon (ald-ctfA-ctfB-bcd) was overexpressed under the strong constitutive thiolase promoter (Pthl), generating PW2 strain. Fermentation results demonstrated that the acid re-assimilation was improved in the host strain and ABE production has been increased to 31.4 g/L (vs. 26.4 g/L in JZ100 strain as the control).

Bayesian Modeling and Adaptive Monte Carlo with Geophysics Applications

Wang, Jianyu Duke University 2013 해외박사(DDOD)

The first part of the thesis focuses on the development of Bayesian modeling motivated by geophysics applications. In Chapter 2, we model the frequency of pyroclastic flows collected from the Soufriere Hills volcano. Multiple change points within the dataset reveal several limitations of existing methods in literature. We propose Bayesian hierarchical models (BBH) by introducing an extra level of hierarchy with hyper parameters, adding a penalty term to constrain close consecutive rates, and using a mixture prior distribution to more accurately match certain circumstances in reality. We end the chapter with a description of the prediction procedure, which is the biggest advantage of the BBH in comparison with other existing methods. In Chapter 3, we develop new statistical techniques to model and relate three complex processes and datasets: the process of extrusion of magma into the lava dome, the growth of the dome as measured by its height, and the rockfalls as an indication of the dome's instability. First, we study the dynamic Negative Binomial branching process and use it to model the rockfalls. Moreover, a generalized regression model is proposed to regress daily rockfall numbers on the extrusion rate and dome height. Furthermore, we solve an inverse problem from the regression model and predict extrusion rate based on rockfalls and dome height. The other focus of the thesis is adaptive Markov chain Monte Carlo (MCMC) method. In Chapter 4, we improve upon the Wang-Landau (WL) algorithm. The WL algorithm is an adaptive sampling scheme that modifies the target distribution to enable the chain to visit low-density regions of the state space. However, the approach relies heavily on a partition of the state space that is left to the user to specify. As a result, the implementation and the use of the algorithm are time-consuming and less automatic. We propose an automatic, adaptive partitioning scheme which continually refines the initial partition as needed during sampling. We show that this overcomes the limitations of the input user-specified partition, making the algorithm significantly more automatic and user-friendly while also making the performance dramatically more reliable and robust. In Chapter 5, we consider the convergence and autocorrelation aspects of MCMC. We propose an Exploration/Exploitation (XX) approach to constructing adaptive MCMC algorithms, which combines adaptation schemes of distinct types. The exploration piece uses adaptation strategies aiming at exploring new regions of the target distribution and thus improving the rate of convergence to equilibrium. The exploitation piece involves an adaptation component which decreases autocorrelation for sampling among regions already discovered. We demonstrate that the combined XX algorithm significantly outperforms either original algorithm on difficult multimodal sampling problems.

Participatory Roles of Urban Trees in Regulating Environmental Quality

Wang, Chenghao ProQuest Dissertations & Theses Arizona State Univ 2019 해외박사(DDOD)

The world has been continuously urbanized and is currently accommodating more than half of the human population. Despite that cities cover only less than 3% of the Earth’s land surface area, they emerged as hotspots of anthropogenic activities. The drastic land use changes, complex three-dimensional urban terrain, and anthropogenic heat emissions alter the transport of mass, heat, and momentum, especially within the urban canopy layer. As a result, cities are confronting numerous environmental challenges such as exacerbated heat stress, frequent air pollution episodes, degraded water quality, increased energy consumption and water use, etc. Green infrastructure, in particular, the use of trees, has been proved as an effective means to improve urban environmental quality in existing research. However, quantitative evaluations of the efficacy of urban trees in regulating air quality and thermal environment are impeded by the limited temporal and spatial scales in field measurements and the deficiency in numerical models. This dissertation aims to advance the simulation of realistic functions of urban trees in both microscale and mesoscale numerical models, and to systematically evaluate the cooling capacity of urban trees under thermal extremes. A coupled large-eddy simulation–Lagrangian stochastic modeling framework is developed for the complex urban environment and is used to evaluate the impact of urban trees on traffic-emitted pollutants. Results show that the model is robust for capturing the dispersion of urban air pollutants and how strategically implemented urban trees can reduce vehicle-emitted pollution. To evaluate the impact of urban trees on the thermal environment, the radiative shading effect of trees are incorporated into the integrated Weather Research and Forecasting model. The mesoscale model is used to simulate shade trees over the contiguous United States, suggesting how the efficacy of urban trees depends on geographical and climatic conditions. The cooling capacity of urban trees and its response to thermal extremes are then quantified for major metropolitans in the United States based on remotely sensed data. It is found the nonlinear temperature dependence of the cooling capacity remarkably resembles the thermodynamic liquid-water–vapor equilibrium. The findings in this dissertation are informative to evaluating and implementing urban trees, and green infrastructure in large, as an important urban planning strategy to cope with emergent global environmental changes.
