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.

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.

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.

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.

Attack Resilient Pulse Based Synchronization

Wang, Zhenqian ProQuest Dissertations & Theses Clemson University 2020 해외박사(DDOD)

Synchronization of pulse-coupled oscillators (PCOs) has gained significant attention recently due to increased applications in sensor networks and wireless communications. However, most existing results are obtained in the absence of malicious attacks. Given the distributed and unattended nature of wireless sensor networks, it is imperative to enhance the resilience of pulse-based synchronization against malicious attacks. To achieve this goal, we first show that by using a carefully designed phase response function (PRF), pulse-based synchronization of PCOs can be guaranteed despite the presence of a stealthy Byzantine attacker, even when legitimate PCOs have different initial phases. Next, we propose a new pulse-based synchronization mechanism to improve the resilience of pulse-based synchronization to multiple stealthy Byzantine attackers. We rigorously characterize the condition for mounting stealthy Byzantine attacks under the proposed new pulse-based synchronization mechanism and prove analytically that synchronization of legitimate oscillators can be achieved even when their initial phases are unrestricted, i.e., randomly distributed in the entire oscillation period. Since most existing results on resilient pulse-based synchronization are obtained only for all-to-all networks, we also propose a new pulse-based synchronization mechanism to improve the resilience of pulse-based synchronization that is applicable under general connected topologies. Under the proposed synchronization mechanism, we prove that synchronization of general connected legitimate PCOs can be guaranteed in the presence of multiple stealthy Byzantine attackers, irrespective of whether the attackers collude with each other or not. The new mechanism can guarantee resilient synchronization even when the initial phases of legitimate oscillators are distributed in a half circle. Then, to relax the limitation of the stealthy attacker model and the constraint on the legitimate oscillators' initial phase distribution, we improved our synchronization mechanism and proved that finite time synchronization of legitimate oscillators can be guaranteed in the presence of multiple Byzantine attackers who can emit attack pulses arbitrarily without any constraint except that practical bit rate constraint renders the number of pulses from an attacker to be finite. The improved mechanism can guarantee synchronization even when the initial phases of all legitimate oscillators are arbitrarily distributed in the entire oscillation period. The new attack resilient pulse-based synchronization approaches in this dissertation are in distinct difference from most existing attack-resilient synchronization algorithms (including the seminal paper from Lamport and Melliar-Smith [1]) which require a priori (almost) synchronization among all legitimate nodes. Numerical simulations are given to confirm the theoretical results.

Translational Regulation Medicated by lncRNA Miat in Cardiac Hypertrophy

Wang, He ProQuest Dissertations & Theses University of Cali 2020 해외박사(DDOD)

Elevated protein synthesis is a fundamental mechanism contributing to a growing heart, during which both translation efficiency and capacity are enhanced. Translation efficiency focus on existing ribosomes in the cytosol, involving how signaling pathways regulate translation initiation, elongation, termination and ribosome recycling to affect translation in a cell. In the cardiomyocytes, mRNA of MHC loading to the polysomes, phosphorylation of ribosomal protein, S6, or of the peptide chain initiation factor, elF-4E by mTOR are well-characterized mechanisms of translation efficiency regulation. While little of translation capacity, or ribosome biogenesis in the heart has been explored. In the heart, ribosome biogenesis is vital in rapid growth conditions such as cardiac development, hypertrophy and pulmonary artery stenosis. The left ventricular weight increases 82% in 4 days following birth in the newborn pig serves as a good example illustrating that regulation of translation efficiency only cannot meet the demand of elevated protein synthesis.Biogenesis of ribosomes, the only and universal translation machinery in the cell, is a tremendous work. All three RNA polymerases, estimated 70% of mature ribosomes and more than 200 assembly factors are devoted in this tightly controlled process. It starts from rDNA transcription, the pre-ribosomal RNA 45S/47S is synthesized by Pol I, followed by ribosomal RNA processing in the nucleoli, carried out by ~150 exonucleases, processing factors and ribosomal subunit assembly factors. The rRNA stands as a scaffold to be decorated by ribosomal proteins, then exported into the cytosol as the 40S and 60S subunits. In the heart, regulation of this assembly chain is largely dark as only few studies examined the rDNA transcription level.In the thesis, we identified a long non-coding RNA Miat is associated with cardiac hypertrophy from an unbiased approach and analyzed the transcriptional change in the pressure overload mouse model to discover that Miat regulates the ribosomal genes and ribosome assembly associated genes. To confirm its impact on translation, we found that Miat is required for increased protein synthesis in cardiomyocytes. More remarkably, lack of Miat showed protective effect to the heart in multiple stress-induced cardiac growth models. Mechanistically, we found that Miat binds to nucleolin (NCL) via conserved binding motifs, and such binding is vital for ribosome biogenesis. NCL is a protein required for rDNA transcription and functions as the early processor of 45S/47S rRNA, however, how NCL mediates 45S/47S rRNA processing in the nucleoli region remained unknown. We found that Miat-NCL binding is vital for rRNA processing, nucleoli formation and ribosome biogenesis in the cardiomyocytes. Therefore, our study provided one of the first detailed examples of how ribosome biogenesis is regulated in the heart and how alteration of translation capacity affects cardiac function in pathological growth.

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.

Resource Allocation for Energy Harvesting Communications

Wang, Zhe Columbia University ProQuest Dissertations & These 2015 해외박사(DDOD)

With the rapid development of energy harvesting technologies, a new paradigm of wireless communications that employs energy harvesting transmitters has become a reality. The renewable energy source enables the flexible deployment of the transmitters and prolongs their lifetimes. To make the best use of the harvested energy, many challenging research issues arise from the new paradigm of communications. In particular, optimal resource (energy, bandwidth, etc.) allocation is key to the design of an efficient wireless system powered by renewable energy sources. In this thesis, we focus on several resource allocation problems for energy harvesting communications, including the energy allocation for a single energy harvesting transmitter, and the joint energy and spectral resource allocation for energy harvesting networks. More specifically, the resource allocation problems discussed in this thesis are summarized as follows. •We solve the problem of designing an affordable optimal energy allocation strategy for the system of energy harvesting active networked tags (EnHANTs), that is adapted to the identification request and the energy harvesting dynamic. We formulate a Markov decision process (MDP) problem to optimize the overall system performance which takes into consideration of both the system activity-time and the communication reliability. To solve the problem, both a static exhaustive search method and a modified policy iteration algorithm are employed to obtain the optimal energy allocation policy. •We develop an energy allocation algorithm to maximize the achievable rate for an access-controlled energy harvesting transmitter based on causal observations of the channel fading states. We formulate the stochastic optimization problem as a Markov decision process (MDP) with continuous states and define an approximate value function based on a piecewise linear fit in terms of the battery state. We show that with the approximate value function, the update in each iteration consists of a group of convex problems with a continuous parameter and we derive the optimal solution to these convex problems in closed-form. Specifically, the computational complexity of the proposed algorithm is significantly lower than that of the standard discrete MDP method. •We propose an efficient iterative algorithm to obtain the optimal energy-bandwidth allocation for multiple flat-fading point-to-point channels, maximizing the weighted sum-rate given the predictions of the energy and channel state. For the special case that each transmitter only communicates with one receiver and the objective is to maximize the total throughput, we develop efficient algorithms for optimally solving the subproblems involved in the iterative algorithm. Moreover, a heuristic algorithm is also proposed for energy-bandwidth allocation based on the causal energy and channel observations. •We consider the energy-bandwidth allocation problem in multiple orthogonal and non-orthogonal flat-fading broadcast channels to maximize the weighted sum-rate given the predictions of energy and channel states. To efficiently obtain the optimal allocation, we extend the iterative algorithm originally proposed for multiple flat-fading point-to-point channels and further develop the optimal algorithms to solve the corresponding subproblems. For the orthogonal broadcast channel, the proportionally-fair (PF) throughput maximization problem is formulated and we derive the equivalence conditions such that the optimal solution can be obtained by solving a weighted throughput maximization problem. The algorithm to obtain the proper weights is also proposed. •We consider the energy-subchannel allocation problem for energy harvesting networks in frequency-selective fading channels. We first assume that the harvested energy and subchannel gains can be predicted and propose an algorithm to efficiently obtain the energy-subchannel allocations for all links over the scheduling period based on controlled water-filling. The proposed algorithm is shown to be asymptotically optimal when the bandwidth of the subchannel goes to zero. A causal algorithm is also proposed based on the Q-learning technique that makes use of the statistics of the energy harvesting and channel fading processes.
